  sub-command that could also be aliased `try-add`. try-load attempts to load
  modulefile(s) but does not raise error (message or code) if module(s) cannot
  be found (does not exist or forbidden).  Error is still raised if an
  evaluation error occurs.  The `try_modulefile` internal state is added to
  transmit the information that the load (or unload when load is proccessed
  during an unload evaluation) is performed in *try* mode or not.  Fixes #392

2021-06-25  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Rework display key for variant  Use a single global
  array '::g_used_va' to track usage of the different variant report form
  (var=val, +var, ...).  Use the {variant=value} syntax to explain enabled or
  disabled boolean variant in display key: {+variant}={variant=on}.  As a
  consequence of last point, '{variant=value}' is added to display key to
  explain the {variant=on} or {variant=off} part of boolean variant key entry.

  * modulecmd.tcl.in: Translate var=val boolean value in canonical boolean
  When variant is specified with the variant=value form, translate any boolean
  value in boolean canonical form (0 or 1).  Specifications are parsed prior
  knowing if variant is defined as a boolean or not. Thus boolean value are
  forbidden on non-boolean variant (see previous commit).

  * modulecmd.tcl.in: Raise error when bool val set on non-bool variant  Raise
  an error when a non-boolean variant defines a boolean value in its accepted
  value list. Integers which also are boolean (0 and 1) are yet accepted on
  non-boolean variant.  As boolean value are translated in canonical form (0
  or 1) when the module specification is parsed, boolean value cannot be
  defined as accepted value of non-boolean variant since it would never get
  matched.

  * modulecmd.tcl.in: Accept + char at end of module name  Accept any number
  of plus (+) character at the end of module name to be part of this module
  name instead of being parsed as a boolean variant character.  '+' character
  should not be followed by alpha character otherwise it will be treated as
  part of boolean variant specification.  Thus 'name+' or 'name++' are

  * modulecmd.tcl.in: Avoid variant collect when not reporting them  Adapt

  report in case these variant information should not be reported.

  * modulecmd.tcl.in: Allow -* arg on cmdline for bool variant  Accept any

  * modulecmd.tcl.in: Add --boolean option to variant mfcmd  Add the --boolean

  is checked against any value accepted as boolean by Tcl as described in Tcl
  manual:  "If string is any of 0, false, no, or off, then Tcl_GetBoolean
  stores a zero value at *boolPtr. If string is any of 1, true, yes, or on,

  state of variant is preserved to end with the exact same loaded module
  properties once reloading is finished.  getVariantList procedure is adapted
  to pass the '2' value to the excl_dflval argument, which means that we want
  to exclude the default value that have been automatically set (so when
  reloading they will be this time also automatically set).

  * modulecmd.tcl.in: Unset variant in collection means default value set  In
  a collection when a variant is not specified (no value set) on the module
  load line it means this variant is set at the default value for variant.
  Code is adapted here in getVariantList and modEq to transmit the is-default
  hint for each variant set on the loaded module against which the module
  specification defined in collection is compared to.  The *missmeandfl*
  option is added to the modVariantCmp procedure to add a specific comparison
  when enabled: if the variant set on loaded module is not the default version
  but this variant is not set on the collection definition, it means module
  specification in collection and loaded module differ.

  * modulecmd.tcl.in: Too soon to rely on autosym on
  getLoadedAltAndSimplifiedName  Autosymbols are not yet ready be used to
  fetch simplified default names when saving/restoring collection. Currently a
  module gets loaded with the default auto-symbol even if there is an explicit
  default set for this module in another enabled modulepath.  Also some
  environment gets loaded and then after user enables the implicit_default and
  advanced_version_spec options, the autosymbols will not be set but modulecmd
  will expect them when saving/restoring collection.

  getMovementBetweenList procedure to compare element in provided lists with
  the modEq procedure when lists are composed of module specifications. Call
  modEq with a comparison of alternative and simplified names of loaded
  modules.  The module restore process in cmdModuleRestore procedure only need
  one call to getMovementBetweenList to get the list of module to unload, then
  another call to get the list of module to load, in order to restore the
  collection. Whether collection is version-pinned or not the modEq call made
  during collection and loaded module comparison will also check collection
  module name against loaded module simplified names.

  * modulecmd.tcl.in: Compute list of alt and simplified names for loaded mods
  Add the getLoadedAltAndSimplifiedName procedure that compute for designated
  loaded module passed as argument the list of its alternative names and
  simplified names (in case this module name version is the implicit default).
  This information is only fetched from the alternative names in case the
  automated symbols are generated: simplified names are part of the
  alternative names in this case. Otherwise the parent module name is resolve
  against currently set modulepath to determine if parent module resolves to
  currently loaded module version.  Add the ability on modEq procedure to
  compare a module pattern against these alternative and simplified names of a
  loaded module: ismodlo argument should be set to '3'.

  * modulecmd.tcl.in: No variant comparison on modEqStatic proc  As specified
  variant is currently only useful for module specification comparison with

  the variant specified for `modspec` as this procedure is only called on
  non-loaded modules contexts

  * modulecmd.tcl.in: Treat alt names of load{ed,ing} mods on modEq  Add the
  `ismodlo` argument to the modEq procedure to determine is passed `mod` is a
  non-loaded module (0), a loaded module (1) or a loading module (2). If `mod`
  is loaded or loading comparison against `pattern` is also performed over the
  alternative names of mod.  This with one call to modEq, all module name and
  its alternatives are tested against pattern: pattern properties are fetched
  and comparison is prepared only once instead of calling modEq procedure over
  each alternative name of module.

  configuration options useless. Thus these 2 options are removed as it was

  * modulecmd.tcl.in: Split reloading_mod state  Split reloading_mod state in
  reloading_sticky and reloading_supersticky states to get the accurate
  information to report in case a module is both sticky and super-sticky and
  one of these stickyness declaration is not honored during a reload attempt.

2020-12-22  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Swap sticky module if stickyness definition is preserved
  Allow a sticky or super-sticky module to be swapped by another modulefile
  version as soon as stickyness definition is still satisfied. For instance,
  if a sticky tag is applied over *foo* module, *foo/1.0* can be swapped by
  *foo/2.0* as *foo* stickyness is preserved. If the sticky tag applies to
  *foo/1.0*, this module cannot be replaced by another version of *foo*
  module.  Such swap may occur when processing a `restore` or a `switch`
  sub-command.

  loading module as the hidden state concerns the `avail` report only.

  module name is displayed on this mode currently.

  Record in user environment the tags applying to loaded modules. Making this

  Consolidate tags set for the modules returned by getModules procedure only
  if called from an avail sub-command, as these informations are only useful
  for this context (list sub-command does not rely on getModules).

  * modulecmd.tcl.in: Record loaded/auto-loaded tags for loaded modules  When
  parsing loaded environment, record a loaded tag for each loaded module or an
  auto-loaded tag if this module has been automatically loaded by another
  module.  Load these tags information at phase #5 of getModules prior
  fetching the tags found from getModules search.  If current user environment
  state is inconsistent do not stop the whole avail process on this error.

  * modulecmd.tcl.in: Allow to recover from cacheCurrentModules error  In case
  the current user environment is stated inconsistent, allow to only report
  this error and not terminate execution.  An exitonerr argument is added to
  cacheCurrentModules procedure to just call reportError procedure instead of
  reportErrorAndExit.

2020-10-25  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Add global/user rc def to module symbol list in any
  cases  When building the module symbol list in phase #1 of getModules
  procedure, also add the definitions coming from global or user rc files even
  if rc definitions should not be part of the result. As these symbolic names
  may match query and make their targetted module from the currently searched
  directory included in result.

2020-10-24  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Output tags along module on avail subcmd  Output the
  tags of the modules returned by the avail sub-command. Adapt module listing
  regular, terse and json output styles to include these tags. These tags are
  enclosed in <> to distinguish them from symbolic versions.  Tags are sorted
  when printed.  No tag report for long output style not to exceed 80 columns.

  * modulecmd.tcl.in: Collect tags for each elt returned by getModules  Add a
  fifth stage for getModules to gather all the tags applying to resulting
  modules. These tags are stored in a g_tagHash global array to be used to
  output these tags along the module they belong to.

  * modulecmd.tcl.in: Refactor eltsuffix mngt on formatListEltToDisplay

  * modulecmd.tcl.in: Rename tag_list var into sym_list for clarity

  * modulecmd.tcl.in: Remove useless tag_list var in findModules

  Thus time taken to fetch a given tag applying to a module is reduced.
  Record module tag specification in an array where key is module root name
  and each tag has its own list of module specification/associated properties
  couplet applying to it. When looking if a given module matches a given tag,
  the associated properties to the tag from first matching module
  specification is returned.

  early filtering for basic searches (non wild, non contains and no wildcard
  character in searched module root name).

  * modulecmd.tcl.in: Optimize hidden property search  Optimize internal
  recording of hidden module specification when parsing modulerc files in

  Record hidden module specification in an array where key is module root
  name. So it can be easy to check if there is some hidden specification to
  test for a given module (based on root name). Within each array entry hidden
  module specifications are sorted by hidden level to be able to search these
  specifications from strongest to weakest hidding level.

  * modulecmd.tcl.in: Save/get module root name from module name and vers spec
  When parsing module version specifiers compute the module root name and
  record it in module version spec structure.  Add the
  getModuleRootFromVersSpec procedure to fetch module root name from a module
  version spec.

  As LOADEDMODULES and MODULEPATH are defined empty in cmdModuleAutoinit

  accessing undefined variable on Windows platform (as setting these variables
  to an empty string means to unset these variables on this platform).

  * modulecmd.tcl.in: unset env var when setting it to empty val on Win  When
  an empty string is set to an environment variable on Windows platform, this
  variable is unset yet still seen defined by 'info exists' command on Tcl,
  which leads to errors when trying to access variable content. So when trying
  to set an empty string to an environment variable on Windows platform, call
  for variable unset instead to reflect underlying OS behavior.

  specific additionnal error message when an attempt to evaluate a *nearly
  forbidden* module is made.  When defined, record message as a property of
  the nearly-forbidden tag.

  * modulecmd.tcl.in: Warn when evaluate a nearly-forbidden module  Produce a
  warning message when a module with *nearly-forbidden* is evaluated. Message
  produced indicate the date time starting when module will effectively be
  forbidden.

  * modulecmd.tcl.in: Set nearly-forbidden tag if in range  Update
  parseApplicationCriteriaArgs procedure to get a *near range in seconds* as
  first argument, then determine in this procedure if the *after* criteria is
  near. Add this information and the *after* criteria value to the list of
  returned values.  With these new informations, the *nearly-forbidden* tag is
  set in module-forbid for module specification that are close to reach the
  *after* limit defined.

  * modulecmd.tcl.in: Introduce '--soft' option to module-hide modfile cmd
  Soften level of camouflage with new option --soft of module-hide Tcl
  modulefile command. Modules targeted by such hide directive are made visible
  as soon as their root name is part of search query.  A '0' hiding level is
  applied to soft hide.

  * modulecmd.tcl.in: Cache isModuleHidden test result

  * modulecmd.tcl.in: Record a hiding level of module  Rather querying if
  module has been declared hidden or not with isModuleDeclHidden procedure,
  query the hiding level of module with getModuleHidingLevel procedure. -1
  means module is not hidden. any value above -1 means module is hidden.

  * modulecmd.tcl.in: Test search query match directly in isModuleHidden  Move
  test that determine if a dot-named module or a declared hidden module is
  matching search query, which renders it visible, into the isModuleHidden
  procedure. Thus this procedure directly tells if module is effectively
  hidden based on search query.

  ensure all module entries have been processed prior setting these symbols.
  If some alias are defined in global or user modulerc, their relative module
  name will automatically be part of names analyzed for auto symbol
  definition. However if available module searched does not match this alias,
  auto symbol were previously defined without all the module entries evaluated
  to know if these symbols should be defined and how.

  * modulecmd.tcl.in: Unhide default symbol on res ctx matching bare mod name
  On a resolution context, like a load sub-command, unhide any default
  symbolic version if search query matches bare module name.

  * modulecmd.tcl.in: Hide mod root name from alt names if default sym hidden
  When loading module, if it matches default version but this symbolic version
  is set hidden, also remove module parent name from the list of alternative
  names to record in environment.

  specifically referred in search query.  As side effect, symbol prefixed by a
  dot character are also made hidden from avail sub-command with this change.

  * modulecmd.tcl.in, testsuite/modules.20-locate/067-hidden.exp: No record of
  hidden alt names  When loading module has alternative names declared hidden
  (alias or symbolic version), withdraw these names from the alternative names
  to record in environment (in MODULES_LMALTNAME) unless they precisely match
  search query used to load module.  Applies to both module declared hidden or
  whose name starts with a dot character.

  * modulecmd.tcl.in: Keep hidden tgt of default sym in resolve context  When
  getModules procedure is called in a resolution context (when it is called by
  getPathToModule proceudre), keep the hidden target of the default symbol if
  search query is equivalent to module name. As during a resolution context
  'mod' query is equivalent to 'mod/default' query.

  * modulecmd.tcl.in, testsuite/modules.20-locate/067-hidden.exp: No specific
  res for sym ver target in cmdModuleSearch  Modulefile targeted by symbolic
  version should be included in getModules result along with symbolic version
  entry. So there is no need to specifically resolve by default symbolic
  version target in cmdModuleSearch procedure.  If symbol's target is found in
  error, record it if search query matches symbol. And if symbol's target has
  not been found in directory where symbol is defined, add this symbol target
  to the list of element to resolve in other modulepath directories later on
  cmdModuleSearch procedure.

  * modulecmd.tcl.in: Resolve icase symver target in getModules  When looking

  * modulecmd.tcl.in: Refactor hversmod_list in getModules  Rather testing if
  symbol target is hidden in phase #1 of getModules procedure when building
  list of symbolic versions, build at this first stage the list of symbols for
  each module having at least one symbol targeting it.  Use this array list,
  named versmod_list, at stage #2 when withdrawing hidden modules unless if
  they are directly targeted by search query or the symbolic versions
  targeting them.

  * modulecmd.tcl.in: Exclude declared hidden mods from getModules res  Adapt
  phase #2 of getModules procedure to withdraw all modules declared hidden
  unless if they match search query. Hidden elements should exactly match
  search query to be retained.

  * modulecmd.tcl.in: Add 'eqspec' test on modEq proc  Add the `eqspec` test
  on modEq procedure to check equality against precise version specification,
  even when extended_default configuration is enabled, and precisely match

  extension library in case this library cannot be found at its main location.
  It adds the ability on specific architecture (e.g., x86_64) to use the
  library build for another architecture compatible with current machine
  (e.g., i686).  When this option is enabled, modulecmd.tcl is produced in a
  way that make it identical whether built from 32bit or 64bit systems. This
  way no conflict happen on EL/Fedora systems when installing both 64bit and
  32bit RPM packages.

  every Unices and its `-G -n` arguments operate the same way.  An error will
  be obtained on Windows platform as `id` command is not known there.
  initStateUsergroups procedure is recorded in modulecmd.tcl as
  __initStateUsergroups and renamed if initStateUsergroups procedure is not
  found from Modules Tcl extension library. A more efficient version of
  initStateUsergroups will be provided in the library later on (not to depend
  on an external command call).

  * modulecmd.tcl.in: Add 'username' sub-cmd to module-info command  Be able
  to fetch current username through `module-info` modulefile command. With no
  extra argument, username is returned. If a name is provided as argument,
  true is returned if this name matches current username, false is returned
  otherwise.

  * modulecmd.tcl.in: Add 'username' state  Create `username` state to collect
  the name of the user running modulecmd.tcl process. Add an initStateUsername
  procedure to initialize this state, which calls `id -u -n` to fetch
  username. This external command is available on every Unices and its `-u -n`
  arguments operate the same way.  An error will be obtained on Windows
  platform as `id` command is not known there.  initStateUsername procedure is
  recorded in modulecmd.tcl as __initStateUsername and renamed if
  initStateUsername procedure is not found from Modules Tcl extension library.
  A more efficient version of initStateUsername will be provided in the
  library later on (not to depend on an external command call).

  Redirect stderr onto stdout when sourcing script in sh-to-mod sub-command in
  order to avoid a warning message put on stderr by script were taken as an
  error by Tcl exec command.  Also mix stdout and stderr messages of script to
  be able to provide all of them to user in case an error occurs during script
  source by shell (exit code found different than 0).  An error returned by
  shell execution is reported and ends sh-to-mod processing.

  * modulecmd.tcl.in: Format string and list for output  Add the strTo and
  listTo procedures to format a string or a list of string making it compliant
  with the destination language. Add support for Tcl and shell output,
  enclosing strings if they are empty or if they contain a space character
  respectively with curly braces or single quotes. And escaping those
  character if used in strings.  Use the new procedures in sh-to-mod to
  enclose/escape script name and its argument to source in shell command. Also
  use listTo in reportCmd, which was previously doing the same enclosing work.
  Make use of reportCmd to output result of sh-to-mod sub-command, in order to
  get the same formatted output than when doing a module display (with tabs
  and colors if enabled).  Add a -nativeargrep argument to reportCmd procedure
  to use (when called for sh-to-mod result) Tcl native string representation
  of list, which automatically enclose string if needed and escape special
  characters if present. Do not make this behavior a default as output made
  for module display should not automatically enclose strings using variable
  value reference (eg. $VAR).

  * modulecmd.tcl.in: Add 'sh-to-mod' procedure  Add the `sh-to-mod' procedure
  that executes script with args through shell and converts environment
  changes the script performs into corresponding modulefile commands.
  Environment changes made by script are found by making shell first outputing
  environment state, then sourcing script and after that outputing resulting
  environment state. Shell full output is after this execution parsed and
  analyzed, comparing environment state prior script source with state after
  script source.  Add support for Bash shell and track changes over
  environment variables, shell functions, shell aliases and current working
  directory.  Result is returned as a list of modulefile commands. Procedure
  is called by cmdModuleShToMod which outputs the modulefile commands with
  modulefile header '#%Module'.

  * modulecmd.tcl.in: Refactor 'reportfd' state initialization  Transform the
  startPager procedure into initStateReportfd to have it automatically called
  first time value of 'reportfd' state is queried (so first time a message has
  to be outputed).  initStateReportfd procedure embeds the output of document
  start in case of structured output mode. This output is done there to avoid
  an infinite loop of reportfd state initialization.  Initialization of the
  'reportfd' state is triggered in initErrorReport if debug mode is enabled to
  have its reportDebug calls processed in buffer mode to get processed in
  correct order (otherwise reportfd initialization will appear first, before
  debug messages stored in buffer).  'already_report' state is removed as it
  is now useless.

  * modulecmd.tcl.in: Refactor 'paginate' state initialization  Transform
  initPager procedure into initStatePaginate and set this procedure as the
  initialization one for the 'paginate' state. Keep a specific call to
  'paginate' state to get it set prior pager initialization.  'pager_started'

  Unsetting the whole `env` array makes Tcl stop monitoring env accesses and

  * modulecmd.tcl.in: Record auto symbol in loaded environment  Once a module,
  which benefits from automatically defined symbolic versions, is loaded, the
  associated auto symbols are recorded in loaded environment among all the
  alternative names applying to the loaded module (in `MODULES_LMALTNAME`
  environment variable).  Auto symbols are distinguished from regular symbols
  by the `as|` prefix which is applied to them.

  * modulecmd.tcl.in: Auto define default/latest symbol when adv_vers_spec
  enabled  When `advanced_version_spec` is enabled, automatically define a
  `default` and `latest` symbolic version for each module (at each module
  depth for deep modules) if those symbols or alias or regular modules with
  these names are not defined.  In case `implicit_default` configuration is
  disabled, these automatic symbolic versions are not defined.  Design
  principles are described in *Default and latest version specifiers*
  document.  Fixes #210.

  avail result order also change when JSON format output is enabled due to
  this code refactoring (as JSON output is not sorted).  It also fix non-wild
  searches (performed during whatis or paths sub-commands) that previously
  matched partial alias, symbolic version or virtual module names. Fully
  matching names for these kind of modules are not only retained for these
  non-wild searches. Test results in 70/190, 70/240 and 70/290 have been
  adapted.

2020-03-23  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Refactor getModules procedure  Rework the full
  getModules procedure to simplify its processing and apply the same match
  tests to every kind of modules (regular modulefile, symbolic, version, alias
  or virtual module).  getModules procedure acts now in 4 phases. First every
  kind of modules are gathered. Then a second phase is set to filter-out
  modules dynamically hidden or forbidden (this filter will be deployed later
  on). Third phase is the elaboration of each directory content to determine
  especially their default and latest versions. At last the fourth phase
  process all gathered results to only keep those matching search query.  As
  the procedure now applies the same mechanisms for all kind of modules, this
  code refactoring has solved several issues:  * An `avail` search over a
  symbolic version targeting a directory now correctly returns the special
  modules (alias and virtual module) lying in this directory.  * `whatis` and
  `paths` searches only return special modules (symbolic version, alias and
  virtual modules) that fully match search query not those that partially
  match it.  * alias and virtual module whose name mention a directory that
  does not exists are correctly handled.  Fixes #168, #327 and #328

  * modulecmd.tcl.in: Rework error stack filtering  Improve error stack output

  procedures. If procedure or caller name in the stack is only known by
  modulecmd.tcl Tcl interpreter (and not modulefile or modulerc Tcl
  interpreter) then this element in the error stack is discarded.

  * modulecmd.tcl.in: Encourage unknown issue report to GitHub project

  * modulecmd.tcl.in: Catch modulefile known errors with error codes  Use
  specific error code (MODULES_ERR_SUBFAILED, MODULES_ERR_GLOBALTOP and
  MODULES_ERR_GLOBAL) rather prepending error message with a specific string
  to throw known errors occurring during modulefile evaluation.

  * modulecmd.tcl.in, testsuite/modules.00-init/120-siteconfig.exp,
  testsuite/modules.00-init/140-color.exp: Report err stack trace for
  siteconfig eval errors  Add to the error message the error stack trace for
  errors occuring during site-specific configuration evaluation. Error stack
  is expunged from the modulecmd.tcl internals to only report information
  relevant to site-specific configuration file.  Introduce the
  `formatErrStackTrace` procedure to tailor error stack trace to filter and
  only keep informations that are relevant to users to understand what code is
  broken.

  * modulecmd.tcl.in: Report err stack trace if error is unknown  Add to the
  error message the error stack trace on a global error when this error is
  unknown.

2020-02-25  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Throw known error with a specific error code  Use
  `MODULES_ERR_KNOWN` error code to throw errors that are known to the module
  system. `knerror` procedure is introduced to throw error with this new
  specific error code set.

  * modulecmd.tcl.in: Render error in main's catch  Define
  `MODULES_ERR_RENDERED` error code, used in `reportErrorAndExit` procedure to
  express that generated error has been rendered (error count increased and
  false value returned on stdout).  If an error is caught in main procedure
  catch, render its error if not done yet (if obtained errorCode is not
  `MODULES_ERR_RENDERED`).  So there is no more need to catch error around
  main call to `module` or `ml` procedure has it will be now correctly handled
  by main catch. Thus in this situation error will only be rendered once.

  with a 2-space padding. As a result error messages appear clearly separated

  * testsuite/modules.00-init/006-procs.exp: ts: adapt perl code which sets
  _mlstatus

  * modulecmd.tcl.in: Lift perl variable strictness for _mlstatus  Declaration
  of $_mlstatus (evaluation status variable) cannot be done as part of
  generated code passed to `eval` statement. If $_mlstatus is declared or
  re-declared as part of evaluated code, defined value cannot be retrieved
  afterward in `module` subroutine.  To be able to retrieve the value of
  $_mlstatus set within generated code evaluation yet avoiding warnings of a
  'use strict;' mode, temporarily disable variable strictness.

  or not from the 'ml' command. A slightly different processing is applied in
  this case as module name may be prefixed by a '-' character when specified
  over the 'ml' command to indicate this module should be unloaded.  When
  mlspec is enabled two lists are returned by parseModuleVersionSpecifier: one
  for the list of the module to load and another for the modules to unload.

  it reduces the number of characters to type to trigger module.  Enablement
  is managed throught a new configuration option named `ml` (which defines
  `MODULES_ML` environment variable when set). It may be enabled by default in
  `modulecmd.tcl` script with option `--enable-ml` passed to `./configure`
  script.

  Introduce a memory cache for the results build up by getModules procedure.
  Done in order to reuse these results if next searches are identical, which
  happens in whatis/search context.  As a side effect a module resolution
  cannot be changed by the evaluation of a modulefile sharing same root name,
  as the initial module resolution to find this modulefile to evaluation has
  cached resolution result.  This side effect should not however impact more
  than the project testsuite as module resolution should not be defined within
  a modulefile but within modulerc files.

  and returning a boolean.

  * modulecmd.tcl.in: Hardwire modMatchAtDepth procedure  Redefine the
  modMatchAtDepth to hardwire indepth and test argument directly at procedure
  definition time to optimize performances.

  * modulecmd.tcl.in: Introduce modEqStatic procedure  Introduce the
  modEqStatic procedure, a more static version of the modEq procedure to use
  in repetitive comparison contexts like done in getModules and
  modMatchAtDepth. In modEqStatic, search query is hard wired which removes
  the need to call getModuleVersSpec each time the procedure is called.
  Instead getModuleVersSpec is called when the modEqStatic procedure is
  defined to get the hard wire elements. Doing so saves a lot of time in the
  getModules routine.

  mod/), fix query processing to correctly return latest or default element in
  case --latest/-L or --default/-d flags are set.  Add an ext_filter argument
  to getModules procedure to indicate that directories of elements matching
  query should be part of the result list even if these directories does not
  match query. This ext_filter argument is enabled by listModules procedure
  when latest or default filters are enabled. These directories are used when
  filtering is enabled to determine what element should be displayed.

  express *greater or equal* (ex: `1.2:`), *lower or equal* (ex: `:1.2`) or
  *between or equal* (ex: `1.1:1.2`) conditions.  Adapt procedures that parse
  module version specifier or compare module version. Error is raised if
  version specified for range are not versions or higher version is lower than
  lower version.  Non 'xdigit' character in higher part of version number is
  considered as a non version number. It avoids symbols like `default`, `new`
  and so on to get in the version range way.

  module version specification toward modMatch procedure to translate it there
  for module matching. modMatch procedure is adapted to apply the translation
  only if a 'trspec' argument is set to 1.  A pattern suffix 'psuf' argument
  is also added to give the ability to append a suffix string to translated
  module name version.

  * modulecmd.tcl.in: Add isModuleSpecHidden to translate vers spec  Introduce

  which is there translated to check if corresponding module names are hidden
  or not.

  * modulecmd.tcl.in: Translate vers spec directly in modMatchAtDepth  Pass

  option  Add the ability to select a module when its version is partially
  specified. Enable this behavior through a new configuration option named
  `extended_default` (which defines `MODULES_EXTENDED_DEFAULT` environment
  variable when set).  When extended_default mechanism is enabled a module
  version may be specified by its starting portion, part separated from the
  rest of the version string by a `.` or `-` character.  When multiple
  versions match partial version specified and only one module should be
  returned, default version (implicit or explicit) among matches is returned.
  In case `implicit_default` is disabled and no explicit default is found
  among matches, an error is returned.  Mechanism may be enabled by default in
  `modulecmd.tcl` script with option `--enable-extended-default` passed to
  `./configure` script.

  conf opt  Introduce the wa_277 configuration option to workaround an issue
  with Tcsh history described on ticket #277.  When option is enabled (which
  sets the MODULES_WA_277 environment variable to 1), an alternative module
  alias is defined which fixes the history mechanism issue. However the
  alternative definition of the module alias weakens shell evaluation of the
  code produced by modulefiles. Characters with special meaning for Tcsh shell
  (like { and }) may not be used anymore in shell alias definition elsewhere
  the evaluation of the code produced by modulefiles will return a syntax
  error.  Fixes #277.

  * modulecmd.tcl.in: Force implicit_default enablement during 'restore'  When
  performing a 'module restore', forcibly enable the implicit_default option
  to correctly match current state against the collection to restore, even if
  this collection was saved with implicit_default enabled and current setup at
  restore time has this option disabled.  implicit_default is then restored to
  its defined value once the match is over. So the load of a module to restore
  from the collection may fail when implicit_default is disabled if this
  module is an implicit default and collection was saved with implicit_default
  enabled.

  should be defined for modules with no default version explicitly defined.
  When enabled, which stays the default behavior, a module version is
  automatically selected (latest one) when the generic name of the module is
  passed. When implicit default selection is disabled, the name of modules to
  evaluate should be fully qualified elsewhere an error is returned. This
  option is set at `./configure` time with the `--enable-implicit-default` and
  `--disable-implicit-default` options. It could be superseded with the
  `MODULES_IMPLICIT_DEFAULT` environment variable, that could be set with
  `config` module sub-command throught the `implicit_default` option.  When
  implicit_default is disabled: - module implicit default versions are
  excluded from 'module avail -d' results. - false is returned when argument
  passed to the 'is-avail' sub-command is a directory without an explicit
  default set in it. - and auto_handling is enabled, the requirement load
  mechanism will fail on requirement relying on module implicit default
  version  Fixes #179.

  order  Add the ability to configure when unloading a module and multiple
  loaded modules match request if firstly loaded module should be choosen or
  lastly loaded module. Default behavior is set at the `./configure` time with
  the `--with-unload-match-order` switch. This default could be superseded
  with the `MODULES_UNLOAD_MATCH_ORDER` environment variable, that could be
  set with `config` module sub-command throught the `unload_match_order`
  option.  This change allows to restore behavior of Modules compatibility
  version where first matching module in loaded module list were unloaded in
  such situation.  By default, lastly loaded module is set for unload (like it
  was before this change) to limit impact on the loaded module list when
  dependencies are woven between these loaded modules.  Even if this change
  enables to change the default behavior, it is highly recommanded to keep it
  as soon your modulefiles express dependencies between each other.  Fixes

2019-01-05  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * init/bash_completion.in, init/fish_completion, init/tcsh_completion.in,
  init/zsh-functions/_module, modulecmd.tcl.in: Report and set 'rcfile' on
  'config' sub-command  Report and be able to set the 'rcfile' configuration,
  linked to the MODULERCFILE environment variable, on the 'config'
  sub-command.

  * init/bash_completion.in, init/fish_completion, init/tcsh_completion.in,
  init/zsh-functions/_module: init: add 'config' sub-cmd to shell comp scripts

  * modulecmd.tcl.in: Rework cmdModuleConfig argument parsing  To handle the
  definition of empty value.

  * modulecmd.tcl.in: Add the ability to report one config on 'config' sub-cmd
  When just a configuration key name is passed to the 'config' sub-command
  (and no value associated to it) just report this configuration key value
  rather reporting all configuration keys.

  * modulecmd.tcl.in: Add ability to unset conf from 'config' sub-cmd  When
  the '--reset' command-line switch and a configuration key name is passed to
  the 'config' sub-cmd, unset the relative environment variable. Ensure this
  configuration key could be altered.

  * modulecmd.tcl.in: Reword cmdModuleConfig data structure  Split details in
  multiple arrays for modularity.

  * modulecmd.tcl.in: Rework displayConfig procedure  Pass configuration value
  directly and re-order arguments.

  * modulecmd.tcl.in: Add ability to set conf from 'config' sub-cmd  When a
  configuration key name and value is passed to the 'config' sub-command, set
  the relative environment variable with passed value. Ensure on the way that
  configuration key name can be altered with an environment variable and that
  passed value is valid.

  loaded  Track if a site configuration has been sourced and if the Tcl
  extension library has been loaded. This information is reported on a
  'config' sub-command among the current state information.

  * modulecmd.tcl.in: Dump Modules state on 'config' sub-cmd with --dump-state
  Add the --dump-state command-line switch to the 'config' module sub-cmd. Add
  a second report table that displays each state value of the current
  modulecmd.tcl execution.  Take this opportunity to move 'path_separator',
  'term_columns', 'debug', 'force' and 'paginate' from the config table to the
  state table.

  Introduce a displayConfig helper procedure that checks if a given
  configuration parameter has been overridden from its default value by
  command-line switch or environment variable. Report configuration value and
  from where it has eventually been overridden.

  * modulecmd.tcl.in: Register use_pager as a global variable  To get access
  to this value, on which the paginate option is based, when reporting
  configuration.

  * modulecmd.tcl.in: Also register colors as a global list  To get access to
  this value, on which the color table is based, when reporting configuration.

2019-01-02  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Introduce 'config' sub-command  Add the 'config'
  sub-command to report all the different parameter set for the tool.

  respectively.  Terminal background color kind can be defined to 'light' or
  'dark'. This value can be set at configure time with the
  --with-terminal-background option or with the environment variable
  MODULES_TERM_BACKGROUND.  If the default color set is not superseded by the
  MODULES_COLORS environment variable, the dark background colors will apply
  if terminal background is set to dark. If the terminal background is set to
  light, the light background colors will apply instead.

  * modulecmd.tcl.in: Color modfile cmd reported by 'display' cmd  Graphically
  enhance the modulefile commands reported on a 'module display' command.
  Introduce the 'cm' SGR key for these modulefile commands.

  * modulecmd.tcl.in: Highlight modfile/collfile name on
  display/help/test/saveshow  Hightlight the modulefile header name reported
  on the display, help and test commands. Following the same trend, highlight
  the collection file header name reported on the saveshow command.

  * modulecmd.tcl.in: Hightlight matched module whatis/search query string

  whatis string result the substring matching the search query string
  following the same process than for module avail search query hightlight.

  * modulecmd.tcl.in: Hightlight matched module avail search query string
  Hightlight in each module avail result the substring matching the search
  query string in which the wildcard characters have been right trimmed off.
  No hightlight is performed if color mode is disabled or if some wildcard
  characters persist after the right trim.

  * modulecmd.tcl.in: Graphically represent 'default' symbol  Instead of
  outputing the 'default' symbol among the whole symbol list, represent it
  graphically with the 'de' SGR key applied to the module name.  If color mode
  is disabled or no specific 'de' SGR key is defined, output 'default' symbol
  like any other symbol.

  * modulecmd.tcl.in: Color sym and its separator differently  Use 'sy' sgr
  key to color symbols and 'se' sgr key to color the separator characters
  surrounding these symbols '(', ':' and ')'.

  * modulecmd.tcl.in: No '@' tag added to aliases when they are colored  Do
  not add a '@' tag, to indicate element reported is an alias, when alias are
  colored (which already indicates the entry is an alias)

  * init/bash_completion.in, init/fish_completion, init/tcsh_completion.in,
  init/zsh-functions/_module: init: run module in --color=never mode in shell
  comp scripts  Ensure color mode is disabled when calling module command in
  the bash, fish, tcsh and zsh completion scripts.

  * modulecmd.tcl.in: Color sym reported by 'list' cmd  Graphically enhance
  symbols on 'module list' command like done for 'module avail'.  Make use of
  formatListEltToLongDisplay and formatListEltToDisplay procedure to format
  the elements to output in the same way than 'module avail'.

  * modulecmd.tcl.in: Color alias/sym reported by 'aliases' cmd  Graphically
  enhance aliases and symbols on 'module aliases' command like done for
  'module avail'.

  * modulecmd.tcl.in: Color dir/alias/syms reported by 'avail' cmd
  Graphically enhance directories, aliases and symbols on 'module avail'
  reports (regular, terse and long). Introduce the 'di', 'al' and 'sy' SGR
  keys respectively for directories, aliases and symbols).

2018-12-28  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Pass elts length to displayElementList proc  Externalize
  from the displayElementList procedure the computation of the length of each
  element to display. This is done to prepare the output of graphically
  enhanced elements from this procedure. Element lengths are computed in each
  procedure building the display list. This is where the graphical enhancement
  will take place so it is the right spot to learn the real length (without
  SGR code) of these elements to output.  Take this opportunity to also change
  displayElementList procedure to pass it the display list as a list argument
  rather as "args" which requires to 'eval' the procedure call.

  * modulecmd.tcl.in: Highlight displayed list header  When reporting list
  elements, hightlight passed header, mainly with the 'hi' sgr key except if
  header is a modulepath, in this case 'mp' sgr key is used.

  * modulecmd.tcl.in: Color modulepaths reported by module use  Graphically
  render modulepaths reported on 'module use' and 'module unuse' with 'mp' sgr
  key.

  * modulecmd.tcl.in: Highlight named element of msg record  Highlight named
  element passed as header to reportMsgRecord procedure (using 'hi' sgr key).

  * modulecmd.tcl.in: Color DEBUG/ERROR/Module ERROR/WARNING/INFO msgs  Make
  use of sgr procedure to graphically render header of ERROR, Module ERROR,
  WARNING and INFO messages (respectively with 'er', 'me', 'wa' and 'in' sgr
  keys).  Graphically render the whole DEBUG message (header + message text)
  with 'db' sgr key.

  * .travis.yml, Makefile, Makefile.inc.in, configure, modulecmd.tcl.in,
  site.exp.in: Introduce colored output  Add the ability to graphically
  enhance some part of the produced output to improve result readability.
  Colored output enablement could be controlled at configure time with the
  --enable-color option, or with the MODULES_COLOR environment variable or
  with the command-line switch --color. MODULES_COLOR variable and --color
  switch accepts the following values: never, auto and always. With the
  --enable-color configure option, the 'auto' color mode is applied. When
  color mode is set to 'auto', output is colored if a terminal is attached to
  stderr.  Colors to apply to each elements can be controlled at configure
  time with the --with-colors option or with the MODULES_COLORS environment
  variable. A color set consists of a list of key=value separated by colon
  where each key represents an output element that can be colored and each
  value represents a SGR code applied to this element to color it.  Thanks to

  still searched in depth, as they can produce virtual modules and in the
  future they may invalidate modulefiles. All files at the search query depth
  level are analyze. And for the directories below this depth level
  modulefiles are analyzed until one is found valid (other modulefiles are

  * modulecmd.tcl.in: Adapt getModules/listModules to --no-indepth mode
  Remove in getModules the result entries collected within the procedure where
  more filename path separator are found than in search query string. This way
  entries related to the content of directories matching query are removed.
  Only entries matching search query at its very same depth level are kept +
  the matching directories holding those entries.  This or these matching
  directories holding entries matching search query are kept to get access to
  the default or the latest entries in these directories if -d (default) or -L
  (latest) filters are enabled.  The directories holding entries are then
  excluded from display output in listModules procedure to keep this
  --no-indepth mode displaying only entries lying at the same directory depth
  level.  When the -d (default) or -L (latest) filters are enabled and the
  --no-indepth mode is enabled too, if search query targets the root content
  of the modulepath, do not apply the output filter. In this situation every
  elements at the root of a modulepath can be considered a default of a latest
  entry.

  * .travis.yml, INSTALL.rst, Makefile, Makefile.inc.in, configure,
  modulecmd.tcl.in, site.exp.in: Introduce --indepth/--no-indepth avail mode
  Add the ability to perform non-recursive avail search by limiting results to
  the elements matching search query and not including elements contained in
  the directories part of the result.  Default behavior is unchanged: in depth
  search is performed. --indepth and --no-indepth command-line switches are
  introduced to control behavior as well as an environment variable:
  MODULES_AVAIL_INDEPTH. Default behavior may also be controlled at
  ./configure time with the --enable-avail-indepth and --disable-avail-indepth
  switches.  The --no-indepth mode is pretty useful to provide an efficient
  glance at the available packages when a lot of different versions exist for
  each of them. Shell completion scripts also benefit from the non-recursive
  view to propose choices corresponding to the current depth level only.
  Moreover I/O operations are reduced on this --no-indepth mode as the full
  modulefile tree is not entirely walked through.  This commit introduces the
  new configure script and modulecmd options and it lays the ground for the
  changes on the module find and the result display that will be made in the
  next commits.  Fixes #150.

  fetch_dotversion argument is added to the getFilesInDirectory Tcl procedure
  and its libtclenvmodules counterpart. This argument is disabled when looking
  at modulepath root content to avoid returning eventual .version file stored
  there.  Shorthand version notation (ex: /1.0) cannot be used in a modulepath

  provides a more IO-optimized way than native Tcl commands perform by
  avoiding specific additional queries to get hidden files like .modulerc and

  * lib/envmodules.c, lib/envmodules.h: Introduce Modules Tcl extension
  library  Introduce Modules Tcl extension library (written in C) to extend
  Tcl language in order to provide more optimized I/O commands than native Tcl
  commands do.  This library first provides a 'readFile' command which
  performs an open, read, close of a given modulefile to fetch its content.
  Compared to the Tcl native open, read, close commands it saves 1 ioctl + 1
  fcntl + N lstat system calls per modulefile.

2018-11-25  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Introduce readFile proc to read a file  Adapt all
  procedures reading file (modulefile, shell init file, collection file) to
  use the readFile procedure for that reading job.  This readFile command is
  defined as a Tcl procedure if not found defined (by the load of the upcoming
  C extension).

  * modulecmd.tcl.in: Always read full modfile on most module cmds  Except for
  path, paths, list, avail and aliases module commands always fully read a
  modulefile whether its full content is needed or just its header to verify
  its validity. Proceed this way to only read file once on commands that first
  just check modulefile validity then read again valid files to get their full
  content.  The path, paths, list, avail and aliases module commands are
  excluded from this 'always read full modulefile' mechanism as they never
  need to get the full modulefile content.  Most files found within
  modulepaths are intended to be modulefiles so always reading full file
  content even for invalid modulefiles should not harm much performances
  compared to the gain of reading every valid modulefiles only once instead of
  two.

  * modulecmd.tcl.in: Cache modfile content read to minimize file ops  If
  modulefile is fully read, cache the content read and the file header
  computed to avoid another file read if the same modulefile need to be read
  multiple times.

2018-11-24  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Call readModuleContent in checkValidModule proc  To read
  a modulefile so the code to read file and analyze its header to check it is
  a valid modulefile is just written once.  readModuleContent procedure has
  been adapted to proceed like checkValidModule did when it is called in a
  only_check_validity mode. In this mode, only the first line of the file is
  read as we just want to parse the header of the file (as it was done
  previously in checkValidModule procedure).

  catch mech for prereq report  When attempting to unload a module, if this
  module has dependent loaded it cannot be unloaded if auto_handling mode is
  disabled. Treat that situation through the cmdModuleUnload error catch
  rather just with a reportError call.  In case this situation happens through
  a 'module unload' command in a modulefile evaluated in load mode, no error
  return code should be set. However in other situations, cmdModuleUnload
  command should return an error code.  So this change fixes 'switch'
  sub-command when the switched-off module cannot be unloaded as it has some
  dependent module loaded. Now it fails the whole switch process and no load
  of the switched-on module is not tried.  Fixes #251.

  * modulecmd.tcl.in: Register and report each evaluation and assoc context
  Better track each module evaluation and the context associated to it in
  order to report a more accurate information on the additional modules loaded
  or unloaded when proceeding the main evaluation request.  When calling for a
  module load or unload, pass a context name to either the cmdModuleLoad or
  cmdModuleUnload procedure called to let it register the module evaluation
  and its associated context into a global structure gathering all these
  informations per top-level evaluation.  Report messages on the additional
  evaluation occuring during a main one are now based on these registered
  information rather on computed list of elements passed to the cmdModuleLoad
  or cmdModuleUnload procedures. As a result a more reliable information is
  obtained, especially during a main load evaluation, where previously some
  unload/load additional evaluation were not seen or were reported against
  another automated mechanism.  Additional evaluation messages are only
  reported if the main evaluation goes to its end, which means that if some
  event forces it to rollback the summary list of actions will not be seen to
  let users better understand the resulting situation (nothing was unloaded or
  loaded) and focus on the error message. Previously finished auto mechanisms
  were immediatly reported which confused people as an error occuring after
  the mechanism leads to a full rollback.  In case an additional evaluation
  fails, the corresponding module is removed from the list of modules on which
  the auto mechanism triggered a load or an unload evaluation.  When unloading
  useless requirements in no-auto mode, these unloads are now reported in
  their correct evaluation order (order of definition found in modulefiles).

  one to the requiring module is selected instead of the farest one.  This
  change makes dependency selection consistent with loaded module selection
  which selects lastly loaded module when multiple modules match search.

  * modulecmd.tcl.in: Add a 'isModuleUnloadable' helper procedure
  isModuleUnloadable checks whether a given loaded module could be
  automatically unloaded or not (it can if it has been automatically loaded
  and no other loaded module requires it).  Use this new procedure in
  getUnloadableLoadedModuleList and cmdModuleUnload procedures. For the latter
  it simplifies the treatment when 'onlyureq' argment is enabled

  * modulecmd.tcl.in, testsuite/modules.50-cmds/375-order.exp,
  testsuite/modules.50-cmds/376-switch.exp: Correct unloadable mod search when
  reverting 'module load/switch'  Select unload candidate from loaded module
  list excluding modules loaded after the current unloading module. So only
  module loaded prior dependent module are taken into account.  Then pass this
  candidate, if any, to cmdModuleUnload and rely on this procedure to unload
  module only if it is unloadable.  Previous commit was relying on the list of
  unloadable modules, obtained from getUnloadableLoadedModuleList procedure,
  which sometimes led to corner cases especially if dependency information
  were not set somehow (no module would be unloaded in that case as
  getUnloadableLoadedModuleList relies only on these dependency information).
  As the candidate is selected to be the closest one from the module requiring
  it, it changes unloading result when multiple candidates are found prior
  requiring module (previously firstly loaded module was unloaded).

  required module should be unloaded if it has been automatically loaded.
  This commit fixes the selection of this module to unload automatically when
  evaluating in unload mode the 'module load' or 'module switch' commands used

  switch' statement but was loaded after the module making these statements,

  revert what has been set at load time.  During an unload evaluation, a
  'module switch' command is converted to a 'module unload' of the switched-on

  * modulecmd.tcl.in: Use NPO deps struct to compute DepUn/DepRe on unload
  Use the No Particular Order dependency structures to get the modules to
  handle via the Dependent Unload and the Dependend Reload mechanisms at
  unload time.  Using these No Particular Order dependency structures help to
  "heal" the loaded environment after an unload batch as some dependent
  modules loaded before their requirements could be reloaded to get an
  unloaded requirement replaced by another loaded after dependent.  This
  change mainly adds the 'nporeq' argument to the getDependentLoadedModuleList
  procedure to use the NPO structures rather the order-dependent ones. Then
  the sortModulePerLoadedAndDepOrder, areModuleConstraintsSatisfied and
  getDirectDependentList procedures are updated in turns to use these NPO
  structures when called by getDependentLoadedModuleList in nporeq mode.

  * modulecmd.tcl.in: Add structs to manipulate NPO requirements  In addition
  to the g_moduleDepend, g_dependHash and g_prereqViolation structures that

  structures that hold requirements between loaded modules whatever their
  loading order (No Particular Order taken into account), which means a
  requirement loaded after its dependent module will be found in the *NPO*
  structures but not in the regular ones.

  no change to the output shell code (output order may vary as some rollback
  may occur after a load tentative if a conflict violation is detected
  afterward).  Also some stderr output messages may change since a load
  tentative is made (so messages outputed within modulefile will be seen).  If
  evaluation attempt fails on something else than a conflict violation, this
  error will take precedence over the conflict error (prereq not found,
  modulefile syntax error, etc).  If modulefile declares multiple conflicts
  which are currently violated, there will be an error message for each of
  them as evaluation is going through the whole modulefile before raising
  conflict errors.

2019-01-15  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Evaluate mod then check conflict violation  Give the
  chance to the 'module unload' statements in modulefile to solve conflict
  that were registered prior the load attempt of this modulefile by evaluating
  modulefile then check afterward if a conflict violation is there rather
  checking if a conflict violation exists (and shout error if there is) before
  evaluating modulefile.  So modulefile is evaluated even if a conflict is
  registered against him prior its evaluation. If a conflict is still set
  after its evaluation (and the evaluation of its requirements) everything is
  rolled back.  The 'module unload' commands could solve these already
  registered conflicts. 'conflict' commands used in the loading modulefile
  will however still break the load immediately if the conflict is seen
  violated to maintain same behavior.  With this change, behavior of these
  'module unload' modulefile commands is restored to what it was able to do
  prior conflict consistency changes, yet this consistency is maintained as
  everything is rolled back in the end if conflict is still there.
  doesModuleConflict procedure has also been changed to look at loading
  modules in addition to loaded modules, since the conflict check triggered by
  'module unload' will not raise an error (error is now raised based on the
  result of the doesModuleConflict call.  Fixes #216

  * modulecmd.tcl.in: Compute loaded mod dependency relations without cycle
  When computing dependency relations between loaded modules and a freshly
  loaded one, do not launch a refresh of those unmet relations for an already
  loaded module with the new one if this relation closes a dependency cycle.
  When parsing the already loaded environment, the loaded module dependency
  relations are computed giving each module only the visibility of modules
  loaded prior it. Modules loaded after one module are not taken into account
  as they have not taken part of its requirements.

  * modulecmd.tcl.in: Inhibit DepRe load phase on load if switch ongoing  If a

  list from the unload action of the switched out module.

  * modulecmd.tcl.in: Report additional load/unload during a module switch
  Report for the top level module switch all the additional modules that have
  been automatically unloaded or loaded during this main switch.  Report
  record is still enabled on the top unload/load actions part of switch
  action, but additional unload/load sumup information is recorded against
  switch report. This way errors popping during these main unload or load
  actions are reported against their relative unload/load record like if an
  unload or load has just occured.

  unload process (due to module load commands in modulefile) then report these
  extra unloads as Useless Requirement Unload (UReqUn)

  * modulecmd.tcl.in: Report additional load/unload during a module load  On a
  top level module load (main load action), report all the additional modules
  that have been unload or loaded for this main load process to succeed.

  A recording ID is set when preparing a load or an unload evaluation. If a
  recording ID is found when running reportError, the message is recorded in a
  global structure rather reported immediately. Once evaluation is finished,
  all messages are rendered under a block.  Improve this way readability of
  those messages when evaluating mode may cascade a lot of stuff.

  * modulecmd.tcl.in: From warn/nuasked to onlyureq/onlyndep args on
  cmdModuleUnload  Change warn and nuasked arguments previously added to
  cmdModuleUnload procedure by onlyureq and onlyndep to better cope needs.
  'onlyureq' indicates only the not required anymore modules should be
  unloaded (not user asked modules or those not required by another loaded
  module). This flag is enabled when dealing with 'module load' commands in
  modulefiles interpreted in unload mode. If a module cannot be unloaded
  because it is required, then no error message is produced.  So 'onlyureq'
  argument replaces both 'warn' and 'nuasked' arguments.  'onlyndep' indicates
  that only modules not required by other modules should be unloaded. It is
  used when dealing with 'module unload' commands in modulefiles interpreted
  in load mode. This is useful when force mode is enabled to avoid breaking
  the dependency of a loaded module when trying to load a module declaring
  this dependency as a module to unload (acts like for conflicts).

  'module load' auto/no-auto handling  More test case adaptation to follow the

  enabled or disabled.  The tests changed here show different behavior whether
  auto_handling is enabled or not. Due to the fact that module unloads is not
  cascaded when auto_handling is enabled and UReqUn modules ares unloaded in
  reverse loaded order, not in the order specified within modulefile. These 2
  behavior changes lead to different result: command order change, unwind
  process when a module to unload is erroneous, or variable resulting value
  when unloading modules compete over same variable to set.

2018-09-15  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Auto handling and 'module unload' commands in modulefile
  'module unload' commands in modulefiles may impact the auto handling mode,
  so a few things need to be adapted:  - on 'load' mode, proceed with the
  unload which may raise error if the module is required by another loaded
  module.  - on 'load' mode, set a conflict toward modules to unload to ensure
  they will not be loaded afterward. If module has not been correctly unloaded
  prior the conflict definition, modulefile defining the 'module unload'
  command will not be loaded.  - on 'unload' mode, does nothing as the defined
  conflict ensure environment consistency and will forbid conflicting module
  load. If conflicting module has been loaded, it means this situation has
  been forced so there is no expectation this module who defines a 'module
  unload' effectively unloads this module which is required by the user.

  auto handling

  * modulecmd.tcl.in: Auto handling and 'module load' commands in modulefile
  'module load' commands in modulefiles may impact the auto handling mode, so
  a few things need to be adapted:  - on a 'load' mode, register each module
  passed to the module load command as a prereq of evaluated modulefile. This
  way the dependency will correctly be tracked  - on an 'unload' mode, proceed
  to the unload action when evaluating the 'module load' statement only if
  auto handling is disabled. Do nothing when evaluating the statement if auto
  handling is enabled, as these modules will be unloaded as part of the UReqUn
  mechanism. This way all unload/reload are triggered from the top unload
  action to ensure nothing will get in the way of the DepUn/DepRe/UReqUn
  processed from there.  Note that on an unload mode, modules are unloaded
  only if no other loaded modules require them and they have not been asked by
  user, elsewhere no unload is made to ensure the consistency of the loaded
  environment (as these modules are explicitely required by user or by another
  loaded module)  Treating these modules to unload through UReqUn mechanism
  leads to some behavior changes:  - unload interpretation is not cascaded
  anymore in this case and every module to unload are processed sequentially -
  a consequence of the previous point is that an error happening when
  processing the unload of a UReqUn module, will not unwinds the whole unload
  process as it does when auto_handling is disabled - unload happens in the
  reverse loaded order, not in the order defined by the 'module load' commands
  in the modulefile - as a consequence of this previous point, environment
  change after the whole unload may be different if the unloaded modules
  compete over a variable to set when unloading (last module to be unloaded
  will not be the same)

  * modulecmd.tcl.in: Remove useless global var in cmdModuleUnload

  * modulecmd.tcl.in: Add 'warn' arg to cmdModuleUnload proc  Add a 'warn'
  argument to the cmdModuleUnload procedure to control whether or not display
  the warning message when a module cannot be unloaded because it is still
  required by other loaded module.  This argument is equal to true every time
  except for the interpretation of 'module load' commands in modulefile when
  mode is 'unload'. In this situation module unload may not be performed if
  module is still required but it is a normal situation like the UReqUn
  mechanism (only the useless modulefiles are automatically unloaded).

  * modulecmd.tcl.in: Avoid unloading mods from getDependentLoadedModuleList
  res  Excludes modules currently being unloaded from the result of
  getDependentLoadedModuleList procedure. This situation may appear when
  unloading a module containing itself a "module load" commands, which is
  translated into a "module unload" command on unload module. When in turns
  this modulefile targetted by the "module load" command is unloaded, it
  should not found its dependent modulefile who is currently being unloaded
  into its dependent result list to avoid UReqUn/DepUn infinite loop.

  * modulecmd.tcl.in: Register loaded module alt names in MODULES_LMALTNAME  A
  module may have alternate names resulting from the module alias or symbolic
  version set through the resolution of its modulefile.  Here we start to keep
  track of these alternative names for every loaded modules by using an
  environment variable: MODULES_LMALTNAME. It follows the same tracking
  principle than used for keeping track of conflicts or prereqs between
  modules.  Helper procedures are introduced to get/set module alternative
  names. Right after loading modulefile, its alternative names are retrieved
  from the ::g_resolvedHash resolving array and set to the
  g_loadedModuleAltname array wich is then used to get and set alternative
  names value without dependency to the alias/symbol global resolving process.

  testsuite/modules.50-cmds/375-deps6.exp: Introduce "Dependent Unload" (DU)
  mechanism  Add the ability when auto handling is enabled to unload modules
  requiring the module asked for unload rather shouting an error.  Dependent
  Unload (DU) mechanism builds list of all modules actively requiring (not
  optionaly requiring it) the module set for unload or actively requiring
  modules part of this DU batch.  These DU modules are then unloaded prior
  main module unload, not to be there anymore once module asked for unload is
  in turn unloaded.  These DU modules also contributes to determine the list
  of Useless Requirement Unload (URU) modules. As unloading the DU modules may
  also add new URU modules.  These DU modules also contributes to determine
  the list of Dependent Reload (DR) modules. As unloading the DU modules may
  also add new DR modules.  Take this opportunity to clarify comments around
  Dependent Reload (DR) and Useless Requirement Unload (URU) mechanisms in
  cmdModuleUnload procedure.  Update "deps" test expectations now the DU
  mechanism is in place.

  * modulecmd.tcl.in: Pass a module list to getUnloadableLoadedModuleList
  Like for getDependentLoadedModuleList procedure makes
  getUnloadableLoadedModuleList able to process a module list passed as
  argument.

  * modulecmd.tcl.in: Compute 'drmodlist' only if auto enabled in
  cmdModuleLoad

  * modulecmd.tcl.in: Rename 'depmod' in 'drmodlist' in cmdModule{Load,Unload}
  Rename local variable 'depmod' into 'drmodlist' (dependent reload module
  list) for clarification.

  * modulecmd.tcl.in: Treat list of elt in appendNoDupToList  Adapt
  appendNoDupToList to treat list of elements rather just a single element

  * modulecmd.tcl.in: Work over 1 list in getDependentLoadedModuleList  Only
  use 'fulllist' as 'testlist' could be merged into 'fulllist'.

  * modulecmd.tcl.in: Work over 1 list in getUnloadableLoadedModuleList  Only
  use 'fulllist' as 'unmodlist' could be deduced from it in the end.

  * modulecmd.tcl.in: Add appendNoDupToList helper proc  Add procedure to
  append to a list an element if this element is not already part of this list

  * modulecmd.tcl.in: Add isInList/notInList helper procs  Introduce two
  helper procedures to check existence of an element in a list: isInList and
  notInList.  When this script compatibility will moved from Tcl>=8.4 to
  Tcl>=8.5, will change these helper procs in 'in' and 'ni'.

  * modulecmd.tcl.in: Add getDirectDependentList helper procedure  Add a
  getDirectDependentList procedure in charge of querying ::g_dependHash array
  to return list of dependent modules, stronly or weakly attached to passed
  mod.

  to get a module list as argument rather a single module name.  Helps to get
  in one call all the dependent modules of those passed as argument.  Also
  improve correctness as sometimes multiple modules may violate constraint of
  another one. To get this module freed, all conflicting modules may set
  unloaded. So if all of these conflicting modules are passed as argument to
  getDependentLoadedModuleList, the dependent module will be seen freed and
  will be part of the procedure result list.

  from main unload  Call from the main unload action the automatic unload of
  prereq modules that became useless due to main module unload.  To achieve
  that, getUnloadableLoadedModuleList procedure now returns to the tree of
  unloadable modules. Then cmdModuleUnload calls over this unloadable module
  list is made in a --no-auto mode not to deviate from what was computed
  before unload/load processing.

  Compute list of unloadable required modules prior unload  When unloading a
  module, its requirements that have been automatically loaded and are not
  required by any other module will automatically be unloaded when their
  dependent module is unloaded.  Compute the list of these unloadable required
  modules prior to the unload of their dependent module, not to be confused by
  currently being reloaded dependent module that may hold a requirement on
  these potentially unloadable modules.  Merge getRequiredLoadedModuleList
  procedure into getUnloadableLoadedModuleList that now takes the name of the
  module being unloaded as argument. Call getUnloadableLoadedModuleList prior
  any module change so determine that a required module will be useless after
  module unload if this required module has only one dependent (module
  currently being unloaded)

  * modulecmd.tcl.in: Add 'direct' arg to getDependentLoadedModuleList proc
  Split meaning of 'strong' argument into a new argument named 'direct'. Now
  strong means active dependency (not an optional one). And direct means only
  first-level dependent, when equals to 0 it means the full dependency tree
  should be returned.

  around main action  When reloading dependent module during a module load or
  a module unload, split this reload process into an unload phase, prior main
  action, than a load phase after main action.  Performing this way helps
  dependent module to get refreshed accurately with an unload phase in same
  situation than their last load. Then load phase of the reload process will
  be able to correctly adapt with new dependency loaded or unloaded.
  Proceeding this way enables modulefiles to adapt their variable definitions
  based on their loaded requirements. However when prereq or conflict
  violation constraint appear, unload stage of a dependent module may not
  correctly unset variable as described in nonreg tests.

2018-08-08  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Add reloadModuleList{Unload,Load}Phase procs  Split

  unloads module list and reloadModuleListLoadPhase that load it again after.
  Adapt cmdModuleReload and cmdModuleSwitch to take advantage of these new
  procedures.

2018-08-06  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Handle uasked flag on cmdModuleSwitch proc  Add a

  module to load during the switch action is asked by user (called on the
  command line or in a first level sourced file) or not.

  * modulecmd.tcl.in: Take disapearing prereq in account on
  getDependentLoadedModuleList  When 'being_unload' argument is set, which
  means passed mod is currently being unloaded, exclude from result list the
  loaded modules requiring passed mod. As this module is being unloaded, these
  dependend modules are entering in a violation state, so they cannot be
  reloaded.  This is achieved by temporarily defining the dependent modules in
  prereq violation state, for the time of the getDependentLoadedModuleList
  procedure execution.

2018-07-09  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Change sortPerModuleLoadedOrder into
  sortModulePerLoadedAndDepOrder  Rename sortPerModuleLoadedOrder proc into
  sortModulePerLoadedAndDepOrder. Sort is now refined to take dependencies
  into account: a dependent module should be placed prior the loaded module
  requiring it.  This refinement is made to avoid reloading multiple times the
  same loaded module when dependent module is set after module requiring it in
  list.

2018-07-08  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Add 'being_unload' arg to getDependentLoadedModuleList
  Indicate to getDependentLoadedModuleList procedure that targeting module is
  being unloaded. In this case the procedure will return loaded modules
  conflicting with passed mod and the dependent modules of these conflicting
  module.  These loaded modules are added to the dependent loaded module list
  since passed mod is being unloaded, they can be reloaded now the conflict
  violation is fixed. This reload garanties the modules previously in conflict
  are now correctly loaded and in an expected loaded order.

2018-07-05  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Introduce a 'force' arg to cmdModuleUnload  Add the
  ability to by-pass requiring modules check when unloading a module with an
  argument on the cmdModuleUnload procedure.  This new 'force' argument is
  enabled when reloading modules as the requirement by-pass will immediately
  be fixed once the required modules are loaded again.  Happens when reloading
  dependent modules on load, unload and switch actions. Some of the dependent
  modules may be excluded from reloading module list as they are in a
  prereq/conflict violation state so the remaining modules to reload may face
  some requiring modules still loaded, thus their reload need to be forced.
  Also enabled when purging loaded modules as all modules should be unloaded
  even if some violations make unloading prereqs before the module requiring
  them.

  * modulecmd.tcl.in: No collection save if mod constraints unsatisfied  Raise

  * modulecmd.tcl.in: Update getDependentLoadedModuleList to return sane deps
  Add a sat_constraint argument to getDependentLoadedModuleList procedure to
  ask for dependent loaded modules whose constraints are satisfied. This
  argument is enabled when reloading dependent modules in load, unload and
  switch actions.  A areModuleConstraintsSatisfied procedure is introduced and
  getDependentLoadedModuleList relies on it to determine if a given loaded
  module has its constraints (prereq and conflict) satisfied as well as all
  loaded modules whose given loaded module depends on.  When no module name is
  passed to areModuleConstraintsSatisfied, this procedure returns if all
  loaded module satisfy their loading constraints.

2018-06-29  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Track loaded mod violating their prereq/conflict def
  Update setModuleDependency and unsetModuleDependency procedures to
  register/unregister in a ::g_prereqViolation array loaded modules violating
  their prereq definition (means they have been loaded in force mode or their
  prereq was unloaded in force mode).  Proceed in a similar way for conflicts
  with a ::g_conflictViolation array, still in setModuleDependency and
  unsetModuleDependency procedures.  For prereq violation, updates of
  dependent loaded module eventual violation is obtained by the re-compute of
  the dependency chain performed in setModuleDependency and
  unsetModuleDependency.  For conflict violation, updates of violation state
  is done for loaded modules conflicting with module processed by
  setModuleDependency or unsetModuleDependency. To achieve that list of
  conflicting-with loaded modules is set in ::g_conflictViolation array. This
  array is handled by setModuleConflictViolation and
  unsetModuleConflictViolation procedures.  doesModuleConflict procedure is
  updated on the way to skip from its result eventual own reflexive conflict,
  as this procedure is now called once mod is effectively loaded and not
  anymore prior mod load (as when it is called from cmdModuleLoad). Also check
  conflicting modules declared by current module are loaded or not.

  getModuleFromLoadingModulefile, getLoadingModuleFileList and
  getLoadingModuleList procedures are introduced to be called instead of their

  modules that have not been asked by user (modules that have been
  automatically loaded as dependency of another loaded module) instead of
  tracking those loaded modules directly asked by user.  As a consequence
  MODULES_LMUASKED is transformed in MODULES_LMNOTUASKED and modulecmd.tcl
  code is adapted to determine the 'user asked' state from this negated
  record.  Adapt the whole testsuite consequently.

  * modulecmd.tcl.in: Rely on isModuleUserAsked rather
  getLoadedModuleUserAskedList  Use isModuleUserAsked procedure rather
  checking list result returned by getLoadedModuleUserAskedList procedure to
  determine a loaded module has been asked by user.

  * modulecmd.tcl.in: Replace reloadDepLoadedModuleList by cmdModuleReload
  Drop reloadDepLoadedModuleList procedure to make use of cmdModuleReload in
  cmdModuleLoad and cmdModuleUnload to reload dependent modules.  Adapt
  cmdModuleReload procedure to pass it a module list. If no list provided,
  proc falls back to the full currently loaded module list.

  * modulecmd.tcl.in: Unload/load dep mod one by one in cmdModuleSwitch  Like
  for reload command, change cmdModuleSwitch to unload then reload dependent
  module list one by one rather unloading/loading user asked modules only and
  rely on the dependency mechanism.  Doing so, the loaded module list that
  need to be reloaded is kept as it is exactly reloaded one by one.

  * modulecmd.tcl.in: No auto unload/load on restore/purge/reload  Call

  behavior (processing each module one by one in specified order) whatever the
  auto_handling state.  Then reload module one by one on restore and reload
  commands whatever the auto_handling state to follow the same principle.

  automatic unload attempt of leaf requirements, once mod has been unloaded,
  with an 'autounload' argument on cmdModuleUnload proc.

  * modulecmd.tcl.in: Add sortPerModuleLoadedOrder proc  Add
  sortPerModuleLoadedOrder procedure to sort passed module list following the
  module loaded order.

  * modulecmd.tcl.in: Rework code to get unload autoloaded mods when no more
  req  Add getRequiredLoadedModuleList proc to return all loaded modules in
  the requirement list of passed mod. This proc is called once mod has been
  unloaded, prior to the deletion of these requirement info in
  cmdModuleUnload.  Add getUnloadableLoadedModuleList proc, to return the
  modules that have been automatically loaded and could now be automatically
  unloaded, as no more modules requires them (mandatory or optionaly). This
  proc takes the result of getRequiredLoadedModuleList as input.

2018-06-01  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Gets dep modules with getDependentLoadedModuleList proc
  Introduce the 'getDependentLoadedModuleList' procedure to retrieve the
  currently loaded modules that require the mod passed as argument. By default
  only strong dependencies are returned (loaded modules directly depending on
  passed mod and not having an alternative module loaded to satisfy their
  prereq). When non-strong dependencies are asked, 'depended by' dependencies
  are searched recursively to return all loaded modules linked to passed
  module.  This new 'getDependentLoadedModuleList' procedure relies on the
  global arrays managed by setModuleDependency procedure. It replaces both
  getDepLoadedModuleList and getActiveDepLoadedModuleList procedures.

2018-05-30  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Move deps-related procs near similar oth procs

  * modulecmd.tcl.in: Build and maintain dep chain between loaded mod
  Introduce setModuleDependency and unsetModuleDependency procedures to build
  and maintain global arrays representing the dependency chain between loaded
  modulefiles based on the prereqs defined by each of these modules.
  setModuleDependency is called when module is loaded or current environment
  state is analyzed (called by setLoadedModule). unsetModuleDependency is
  called when module is unloaded (called by unsetLoadedModule).  The
  g_moduleDepend array is set for each loaded module as a mirror of their
  relative definition in g_loadedModulePrereq, where module reference in the
  prereq definition is replaced by the name of the actual loaded modulefile
  matching the module reference.  When a module reference of a prereq
  definition has no match among the currently loaded modulefiles, this unmet
  dependency is registered instead in the g_moduleUnmetDep global array. This
  situation happens when an optional dependency is not satisfied or if the
  load of a module has been forced (no dependency loaded prior to the load of
  the asked module).  Reverse arrays are also set (g_dependHash and
  g_unmetDepHash) to easy the search of registered elements.  When a new
  module is loaded, setModuleDependency looks if this new module was
  previously set as an unmet dependency. If it is the case, update dependent
  loaded modules dependency definition now the unmet dep is satisfied.

  * modulecmd.tcl.in: No uasked found on current env means all are uasked
  When looking at the current environement state in cacheCurrentModules
  procedure, if no user asked modules are found then all loaded modules are
  user asked modules.  Helps transition between a Modules version not knowing
  about 'user asked' modules and a newer Modules version introducting this
  tracking feature. Environment setup on the previous Modules version will
  still be functionnal if newer Modules version is upgraded live.

  * modulecmd.tcl.in: Ignore '--notuasked' flag in case it is passed on module
  load  --notuasked flag enables to keep track of the user asked state in
  saved collection (by flagging those not directly asked by user). Ignore it
  if passed directly to a 'module load' command (do not raise error) in case a
  collection file is sourced like a shell script.  Do not advertise this new
  flag as it has no effect and should be kept internal as user asked mechanism
  is automatically controlled from the location the module load command is
  issued.

  * modulecmd.tcl.in: No uasked found in collection means all are usaked  If
  none of the loaded modules found in collection is marked 'user asked', this
  means all modules saved are user asked to make collections saved prior to
  the user asked change still valid on new Modules version.

  * modulecmd.tcl.in: Track user asked loaded modules whatever auto_handling
  state  Keep track of the loaded modules asked by user whether the
  auto_handling option is enabled or disabled. A loaded module has been asked
  by user when its load order is coming from the user not from the evaluation
  of a modulefile.  Keeping track of this state in any cases will help to
  introduce per-module command automatic handling. Also saved collections do
  not break when auto_handling is enabled or disabled on Modules installation
  afterward.  An 'uasked' first position argument is set on cmdModuleLoad
  procedure to pass the user asked state. cmdModuleReload is reworked to
  correctly restore the user asked state for each module unloaded in its first
  operation phase.  cmdModuleSwitch always sets the module it loads as user
  asked. Should be discussed later on in conjunction with the behavior of this
  sub-command when called from a modulefile.  Collections sub-commands and
  related utility procedures have been reworked to save and restore the
  non-'user asked' state of the loaded modules. Non-'user asked' state is
  recorded rather 'user asked' state to fit collection saved prior to this
  change were every modules mentionned in collection are considered 'user
  asked'. When restoring a collection currently loaded modules are unloaded to
  be loaded again even if they got same loading position than in collection
  but a different user asked state. Non-user asked state is saved in
  collection by adding the '--notuasked' argument on recorded module load
  lines.

  * modulecmd.tcl.in: Register conflict/prereq/usaked whatever auto_handling
  state  Get, set and export in environment loaded modules declared conflicts,
  prereqs and their 'user asked' state whether the auto_handling option is
  enabled or not.  Keep g_auto_handling to control automated actions but
  information registering is perfomed in any cases.  Will help to introduce
  per-module command automatic handling and by-pass mechanism, still keeping a
  consistent intel.

  * modulecmd.tcl.in: Initial rework of mod prereq internal handling  Change
  module prereq internal handling (registering/unregistering in global
  structures) to get similar handling than loaded module list.  Rename
  g_lmPrereq into g_loadedModulePrereq.  Remove ModulesCurrentPrereq global
  list, that were registering the prereq list of the currently evaluated
  module. Now directly registers into g_loadedModulePrereq. If evaluation goes
  wrong and is aborted, then prereqs registered in g_loadedModulePrereq are
  unregistered to correctly restore state prior evaluation.  Introduce set,
  unset and get accessors for the g_modulesPrereq array. getLoadedPrereq is
  also able to return its result serialized to manage MODULES_LMPREREQ
  environment variable.

  * modulecmd.tcl.in: Rework mod conflict internal handling  Change module
  conflict internal handling (registering/unregistering in global structures)
  to get similar handling than loaded module list.  Rename g_lmConflict into
  g_loadedModuleConflict.  Remove ModulesCurrentConflict global list, that
  were registering the conflict list of the currently evaluated module. Now
  directly registers into g_loadedModuleConflict, to be able to check only one
  structure to get both loaded and loading defined conflicts. If evaluation
  goes wrong and is aborted, then conflicts registered in
  g_loadedModuleConflict are unregistered to correctly restore state prior
  evaluation.  Introduce set, unset and get accessors for the
  g_loadedModuleConflict array. getLoadedConflict is also able to return its
  result serialized to manage MODULES_LMCONFLICT environment variable.  A
  doesModuleConflict procedure is also added to return whether or not passed
  module conflicts with currently defined rules.

  * modulecmd.tcl.in: Register module asked for load in MODULES_LMUASKED
  Change name of the environment variable used to register the names of
  modules explicitely asked for load by user (not loaded automatically as
  dependency): from _LMSTICKY_ to MODULES_LMUASKED in order to get a MODULES_
  common prefix for all Modules-specific environment variables.

2014-05-13  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Introducing automatic module dependency resolution
  Introduce an automatic module dependency resolution by attempting during a
  "module load" to load modules declared as prereq and attempting during a
  "module unload" to unload modules declared as prereq if they have been
  loaded automatically.  To distinguish between modules loaded upon user
  request or automatically for dependency resolution, module load requested by
  user are registered as "sticky" in _LMSTICKY_ environment variable.
  Additionnally all switched modules are considered sticky.  Module commands
  managing the whole set of loaded modules (save, restore, purge and reload)
  have been adapted to only work over the sticky modules to take benefit from
  the dependency resolution. Moreover, when reloading modules declaring a
  prereq during a switch, load or unload action, only sticky modules are
  reloaded.  Original dependency management behavior is preserved by default.
  Automatic dependency resolution can be enabled by setting to 0 the
  g_auto_resolve_dep variable in modulecmd.tcl script.

  * modulecmd.tcl.in: Registering prereq of loaded modules to ensure they are
  satisfied  When defining a prereq with module "b" in module "a", this prereq
  is not satisfied when module "b" is unloaded whereas module "a" is still
  loaded. It seems interesting to guaranty that prereq modules cannot be
  unloaded if modules requiring them are still loaded.  To do so, this patch
  introduces the registration of the prereq declared by loaded modules in
  _LMPREREQ_ environment variable. Checks have been added to cmdModuleUnload
  procedure to forbid the unload of modules targeted by a registered prereq.
  In case of a switch action, all modules declaring a prereq on the switched
  module are reloaded. cmdModuleSwitch procedure first unloads the modules
  declaring prereq, then proceed switch as usual and after that loads again
  the modules declaring prereq.  Similarly to switch action, modules declaring
  an optional prereq on a module are reloaded when this module is loaded or
  unloaded. cmdModuleLoad and cmdModuleUnload procedures reload the modules
  declaring prereq after their main load/unload process to avoid reloading
  modules whereas prereq-module fails to load/unload.  Original load control
  behavior is preserved by default. New behavior can be enabled by setting to
  0 the g_orig_load_control variable in modulecmd.tcl script.

  * modulecmd.tcl.in: Registering conflict of loaded modules to ensure they
  are satisfied  When defining a conflict with module "b" in module "a", this
  conflict is not satisfied when loading module "b" unless this module defines
  a conflict with "a". Since it happens that modules "a" and "b" are not
  managed by the same people, it seems interesting to guaranty that conflicts
  defined by loaded modules are always satisfied.  To do so, this patch
  introduces the registration of the conflict declared by loaded modules in
  _LMCONFLICT_ environment variable. Checks have been added to cmdModuleLoad
  procedure to forbid the load of modules targeted by a registered conflict.
  Since modulefile may directly call module load, an is-loading procedure has
  been introduced to also ensure that current module will not be loaded if it
  defines a conflict toward a module which is currently loading.  Original
  load control behavior is preserved by default. New behavior can be enabled
  by setting to 0 the g_orig_load_control variable in modulecmd.tcl script.

  determine calling shell name.  Doing so will avoid some external command
  call when running bash or zsh. Also if people source /etc/profile script in
  their own bash or zsh script it will correctly determine calling shell name,
  as parent process in this case is the script name.  Cannot determine shell
  name on ksh with a variable due to the lack of a consistent detection
  mechanism across all ksh flavors [1].  Fixes #173  [1]

  to val in interp context  Interpreting a setenv modulefile order during an
  unload evaluation, variable is still set to be unset in generated shell code
  but it is set to the value defined on the setenv order in the interpreter
  context instead of being cleared.  This change is made to recover and
  improve behavior of compat version and previous version of modulecmd.tcl
  where variable's value found in environment were not touch in interpreater
  context.  This is useful when using environment variable value to
  append/prepend-path another variable. This change enables to correctly unset
  this other variable on an unload evaluation. Was previously not unset since
  the first variable used to edit the second was found cleared.  This change
  is currently limited to the setenv order and does not apply to the
  prepend-path and append-path, where during an unload evaluation variable
  value part is removed from variable also in interpreter context. Need to
  distinguish value in interpreter context from value to set in shell output
  code to also apply this mechanism to path edition modulefile orders.

  * modulecmd.tcl.in: Pass cur itrp ref in initInterpCommands to aliases
  needing it  Sets in initInterpCommands procedure interpreter reference as
  first argument to interpreter alias requiring it, rather doing it in
  initModfileModeAliases where actual interpreter reference is not known (as
  this procedure is called at first time a mode-specific interp is created,
  but not on subsequent times when another interp of same mode but working in
  a nested level is build up).  Now initModfileModeAliases defines a specific
  __itrp__ keyword to let initInterpCommands know that the argument to pass to
  the alias to define is the actual interp reference.

  getEvalModuleStackDepth to learn nb of mod in eval  Get the number of either
  modulerc/modulefile currently being evaluated (nested evaluation) with a new
  procedure called getEvalModuleStackDepth, relying on the number of element
  of the g_moduleNameStack global list.  Use this new procedure rather [info
  level] to determine if module procedure is called at top level or not and to
  determine the slave interpreter to use (an interpreter is reused to evaluate
  a modulefile from same evaluation nested level).  Gives a more precise
  information on modulefile evaluation depth level than [info level] which

  this result. For instance searching for modules 'foo' in '/path/to/dir' may
  use the cache result saved after the search of '*' modules in 'path/to/dir'.
  This superset result is then filtered-out whithin the getModules procedure.

  This procedure checks the environment variable targeted by the command and
  initialize it as an empty string if undefined.  Proceed this way to reduce

  if undefined to avoid 'undefined variable' errors during evaluation if
  environment variable value are referred to later in modulefile.  Value set
  to variable are not the correct one (no value set if variable defined, empty
  string set if variable is undefined) but it should not affect the whatis

  reportCmd on a display evaluation mode.  As a side effect of this change,
  commands are reported even if their execution raise an error (helps to see

  existing reference counter variable when running setenv/unsetenv commands.
  Adapt and add tests to put in light behaviors when unloading a
  standardly-set variable going through append-path/prepend-path. The
  standardly-set variable is transformed into a path-like variable through the
  evaluation, resulting in the end in the definition of a reference counter
  variable (if variable is not setenv/unsetenv during evaluation) or in the
  deletion of this reference counter variable (if setenv/unsetenv during
  evaluation).

  deletion with unset-env  Make use of the 'unset-env' procedure to delete an
  environment variable and propagate deletion to the running shell (outputing
  deletion command to stdout).  Deletion is propagated only if currently in
  'load' or 'unload' evaluation mode.  unset-env procedure distinguishes
  environment variables from those set for Modules internal use, like path
  reference counter variables. Internal variables are purely unset whereas
  other environment variables are just cleared, not unset, to avoid breaking
  later reference to these variables in modulefiles.  In case of environment
  variable for internal use, variable deletion is propagated to shell only if
  variable was found set. Aligning all unsets on this rule gives no unset of
  reference counter variable on unload mode if the variable is not found
  defined at that time.  Adapt expected test results for the above side
  effect.

  function for Python to accept being called with no argument.

  argument list (after command name) is cleared in this situation to always
  get the general usage message rather triggering the help mode of an
  arbitrary modulefile.

  general pager configuration not compatible with Modules pager handling.
  This change makes Modules pager implementation moving away from Git pager
  implementation (which was taken as reference to model configuration behavior
  of Modules pager). Git is able to withstand any pager configuration,
  especially to quit pager if content fits in one screen. Not the case with
  our implementation currently, so it is safer to only take into account pager
  configuration that is specific to Modules.  Adapt doc and tests accordingly.
  Fixes #146

2018-02-10  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Start pager only if some text has to be printed  Start
  pager if enabled at first message to print on stderr. No pager is started
  anymore when nothing need to be outputted on stderr.  To achieve that pager
  setup is split on a configuration and enablement initialization (initPager
  procedure) and startup (startPager procedure). Split in two procedures is
  required to report debug messages on pager configuration that will be
  printed through the started pager.  Partially fix #146.

  * modulecmd.tcl.in: Split report procedures in pre and post init err report
  Define 2 procedures for reportDebug, reportErrorAndExit and report. First to
  use before error report being initialized, to bufferize messages. The second
  one to be used to effectively report messages once error report being
  initialized.  initErrorReport procedure handles the procedure switch by use
  of 'rename' Tcl command.  g_init_errreport variable is removed as the
  procedure split make it useless.  No performance change is observed.

  module alias target, to correctly handle virtual modules. Modulepath
  directory is retrieved, when detecting a virtual module, from the modulerc
  file that has defined this virtual module.

  * modulecmd.tcl.in: Handle loaded virtual modules on 'list' cmd  Introduce
  'isModuleVirtual' procedure to detect a module is virtual based on its name
  and modulefile. A module is stated virtual if its name cannot be found at
  end of its modulefile name.  When looking at loaded modules during a 'list'
  command, treat specifically virtual modules, almost like full path modules.
  Tags on loaded virtual module are not search as once loaded we do not know
  anymore from what modulepath directory the virtual module was coming from.

  not possible as relative paths were dependent of the location from where the
  module command was executed.  If ModulesCurrentModulefile variable is not

  is gathered in the execute-modulefile and execute-modulerc procedures to

  * modulecmd.tcl.in: Introduce 'module-virtual' modulefile command  Introduce
  the virtual module concept with the 'module-virtual' modulefile command.
  This new command takes a module name as first argument and a modulefile
  location as second argument.  A virtual module stands for this module name
  associated to a modulefile. The modulefile is the script interpreted when
  loading or unloading the virtual module which appears or can be found with
  its virtual name.  Like a module aliases, virtual modules are expected to be
  defined within modulerc files (at whatever rc level). Virtual modules can be
  targeted by aliases or symbolic versions. They also compete with aliases and
  regular modules for the implicit default version of a module.  Multiple
  virtual modules may target the same modulefile, which can distinguish
  between these various virtual names by use of the "[module-info name]"
  command.  A virtual module cannot be loaded using a full path name (merge of
  its module path and its module name) as this file does not exist.  Based on
  a proof of concept made by Bert Wesarg [1].  [1]

  By not relying on an environment variable we ensure this etc/rc will always
  be read, if it exists, whatever the current environment state.  Location of
  this etc/rc is based on @prefix@ defined at configure time which is also the
  basis for the MODULESHOME value, so this change should not have an impact if
  MODULESHOME variable were not manipulated afterward.  This change is useful
  when using module through commands resetting the environment like 'sudo'
  (see RH#1443124, RH#1139165 [1])  module.1 man page is already mentionning
  @prefix@/etc/rc, no change needed there.  Adapt testsuite to provide a way
  to test the use of a @prefix@/etc/rc file for the whole 'make test'
  duration, with 'make install-testetcrc'.  [1]

  MODULES_COLLECTION_PIN_VERSION  Add the ability to always record module name
  + version even if this version corresponds to the default one.  By default,
  version number is omitted if it corresponds to the implicit or explicitly
  set default version. If MODULES_COLLECTION_PIN_VERSION environment variable
  is set to 1, version number is always recorded.  When restoring a
  collection, we do not know for sure if it was saved with pinned versions or
  not, so module load and unload movements are determined on both simplified
  or raw module list. Results with less module to load or unload (means with
  more matches between module lists) are kept.  Acknowledgment: this
  development has been made and funded within the framework of the PRACE Fifth
  Implementation Phase (PRACE-5IP) project (http://www.prace-ri.eu/).

  without any specific assignment.  Prior to modulecmd.tcl execution, the

  run with an ok statement when everything goes well. It was the case for
  avail, aliases, list, apropos/search/keyword, save*, init* and help (without
  arg). However when some errors occurred on these commands, they were
  returning an error statement.  To apply same behavior to all commands
  whatever the result is (error occurred or not) a call to renderSettings is
  made after all commands which will produce a true or false statement sent to
  stdout.  As a consequence the return value of all module sub-command call
  can be checked against a true/false value.  Even if modulecmd.tcl should now
  return a true/false statement, keep checks on the intermediate variable
  required on python and cmake shells to guaranty a false boolean return in
  case very bad stuff happened within modulecmd.tcl not producing the
  intermediate variable statement.  Adapt all non-reg tests to get correct
  return code (OK or ERR).  Note that when apropos/search/keyword hit a
  modulefile error when interpreting, it will return a 'false' statement even
  if result output seem correct (as these kind of error are not hidden to
  better read obtained result).

  testsuite/modules.70-maint/070-display.exp: Make shells return 'false'
  rather raising exception  Use an expression for each supported shell to say
  'false' when error occurred during modulecmd.tcl process. This was already
  the behavior for the sh/csh/fish shells but a change is made to the other
  lang shells where previously an exception was raised in case of error.
  Moving from a raised exception to a boolean return seem to be more
  appropriate for the calling scripts, which will not explode anymore each
  time a modulefile is not found for instance.  Boolean return opens the path
  to a return value check on all supported shells (was only possible on
  sh/csh/fish before that).  Now all shells are aligned with a 'true' value
  returned in case of success rendering and a 'false' value returned in case
  of error.

  'renderOk' procedure is added following same principle than 'renderError'.
  These code additions keep the ability for the rendering to be called from
  the shell module function or from a direct execution. To achieve that
  instead of using a 'return true' statement, which would had no meaning
  outside of a module function, a true statement is expressed. Most of the
  shells will return the result from the last evaluated statement.  For shells
  not returning result from the last evaluated statement (python, cmake), a
  variable is set to true. This variable will be used in module function to
  return the status value.  For the sh/csh/fish shells, no code is rendered if
  something has already been sent to stdout, as in this case the last lines
  will return 'true' by itself.

  variable to silent the xtrace and verbose output on sh-kind shells.  When
  set (means MODULES_SILENT_SHELL_DEBUG=1), current xtrace and verbose flags
  are saved then these shell properties are disabled. Once execution is
  finished, saved setup is restored.  This mechanism is defined on
  initialization scripts, at the beginning to silent, at the end to restore
  defined behavior. It is also defined within the module function following
  exact same principle.  By default, xtrace and verbose shell properties are
  applied to module function and initialization script if enabled in calling
  shell script or interactive session. These properties are disabled in module
  context only if MODULES_SILENT_SHELL_DEBUG is set to '1'.  Notice that if
  xtrace/verbose properties are set, shell code that leads to disable them
  when MODULES_SILENT_SHELL_DEBUG is set will be outputed as debugging is set
  during these operations.  The mechanism only applies to the SH-shell family.

  * modulecmd.tcl.in: Introduce quarantine runtime (sh shells only)  Introduce
  a mechanism set within module function definition to modify modulecmd.tcl
  runtime environment in order to protect it from side-effect coming from the
  current user environment definition.  For instance, if modulecmd.tcl is
  installed to work with a tclsh version 8.4 but current environment has
  enabled a libtcl8.6.so in LD_LIBRARY_PATH, this environment will not be able
  to run modulecmd.tcl anymore. Quarantine runtime mechanism helps to define a
  sane LD_LIBRARY_PATH value which will be set for modulecmd.tcl to guaranty
  correct operations.  The mechanism is piloted by environment variables.
  First of all MODULES_RUN_QUARANTINE, a space-separated list of environment
  variable names. Every variable found in MODULES_RUN_QUARANTINE will be set
  in quarantine during the modulecmd.tcl runtime. Their value will be set
  empty or set to the value of the corresponding MODULES_RUNENV_<VAR>
  environment variable if defined. The initial value these variables have will
  be passed to modulecmd.tcl via the '<VAR>_modquar' variable. Then once
  modulecmd.tcl is started it restores <VAR> to the content found in
  <VAR>_modquar (its original value).  This commit adds the feature for the
  SH-kind shells only (sh, bash, ksh and zsh). Some complex shell code was
  required to distinguish an unset variable from a variable set empty: `eval
  'echo ${'$var'+x}'`.  Code is also slightly different for sh shell than
  other sh-kind shells due to a different supported syntax to define local
  variable. No 'typeset' builtin is found on a pure sh shell, like dash. 'ksh'
  on its side does not understand 'local' builtin. So code for 'sh' shell uses
  'local' builtin and other sh-kind shells use 'typeset'.  Zsh code has a
  difference compared to the other sh shells, as word splitting need to be
  explicitly enabled with a '${=var}' syntax.  Space is used as variable name
  separator in MODULES_RUN_QUARANTINE variable, as it is the most convenient
  separator to work with in SH-kind shells (no need to adapt IFS).

2017-10-29  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Add '-K' option to less pager  Quit less pager on
  interupt (^C typed) instead of trapping it. As module is set as a shell
  function, SIGINT signal is first send to this function and its underlying
  children (modulecmd + less pager). If less trap this interput it will remain
  alone after end of module function and modulecmd process, but not in direct
  interaction with terminal. So it seems preferable to end pager at the same
  time its parent process vanish.  Without option '-K', less continues until
  reading all its remaining stdin buffer.  An alternative would be to trap
  signal within modulecmd, but it implies using the TclX extension to get
  access to the 'signal' procedure. Moreover, after effect will quite be the
  same, as shell function is terminated and remaining processed are not in
  direct interaction with terminal.  For the record, trapping signal in
  modulecmd makes this process able to finish right after the pager command.
  Procedure designated to trap signal will be run once currently blocking IO
  is processed. Then close of pipe descriptor will finished once pager finish
  in turns to process it remaining stdin buffer.  Instead of using TclX,
  Expect extension may be used to trap signal but with exact same handling
  behavior than TclX.  Another lead would be to trap/untrap signal within
  shell function, but signal is then completely ignored.

  * modulecmd.tcl.in: Increase pager fd buffer size to 64k  More aligned with
  the buffer size 'less' is setting-up. Should be sufficent to handle most
  kind of output content in one pass.

  * modulecmd.tcl.in: Handle case when pager is ended (killed or quit)  Catch
  cases when pager is ended before all messages are reported to it ('q'
  pressed or process killed).  Error raised from 'puts' call are ignored with
  'catch'. As we handle here informational messages, do not end the full
  modulecmd process when message channel is dead.  Also protect pager fd
  operations in cleanupAndExit, in case pipe is not operational anymore.

  overhead of the pager setup.

2017-10-27  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * doc/source/module.rst, modulecmd.tcl.in: Introduce pager support  Paginate
  stderr output into paging command, using 'less' by default, following the
  same fashion and behavior than 'git' command.  Pager is enabled by default
  in modulecmd script. New global variables 'g_use_pager', 'g_pager' and
  'g_pager_opts' control default behavior of module command.  Pager is enabled
  only if stderr stream is attached to a terminal.  Pager setup can then be
  superseeded by environment variables. If LESS variable is set and paging
  command is set to 'less', default pager options are cleared to use those
  defined in LESS variable.  If MODULES_PAGER variable is defined, its value
  superseeds paging activation, command and options. If this variable is
  empty, paging is disabled.  If PAGER variable is defined and MODULES_PAGER
  is unset, PAGER value superseeds paging activation, command and options. If
  this variable is empty, paging is disabled.  Default behavior and
  MODULES_PAGER or PAGER environment variables can be superseeded by
  command-line options: --paginate to enable paging and --no-pager to disable
  it.  When pager is enabled, a pipe file descripted is ignited to the paging
  command and option for stderr stream. Once set, this file descriptor is used
  by all report procedures to output message content, rather using stderr.
  modulecmd command-line parse has been revised not to output message during
  argument treatment. Debug, warning and error messages are saved to then be
  displayed once pager setup is achieved.  An 'initPager' procedure is
  introduced to configure then start paging. A 'cleanupAndExit' is added to
  close pager before exiting if pager has been started.

  testsuite/modules.70-maint/120-autoinit.exp: testsuite: check various
  autoinit setup  Add example modulerc and .modulespath configuration and test
  autoinit behavior when these examples are installed in init directory.

  * modulecmd.tcl.in: Deprecated @prefix@/modulerc in autoinit  Keep behavior
  of init script where only one modulerc file is sourced if it exists (in
  @initdir@).

  init/sh.in, init/tcl.in, init/zsh.in: init: shell scripts now rely on
  autoinit command  Make use of autoinit module command to initialize module
  command and its initial surrounding environment (default value for
  MODULESHOME, MODULEPATH, LOADEDMODULES and parse of init/.modulespath).
  Then if compatibility version is currently activated redefined the module
  command to point to the compat binary. But the compat version will benefit
  from the surrounding environment initialization made by autoinit.  With this
  change, activated compatibility version will also get its environment
  initialized by the init/modulerc file whereas before this change only the
  main version was affected by this setup file.

  * modulecmd.tcl.in, site.exp.in,
  testsuite/modules.70-maint/120-autoinit.exp: Use configure tags to set dir
  locations in autoinit  Define in autoinit command the value of MODULESHOME
  based on @prefix@ configure tag and initialization directory based on
  @initdir@ rather guessing them from modulecmd.tcl location.  Same location
  approach that initialization scripts this way.

2017-10-19  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * Makefile, modulecmd.tcl.in: Parse init/.modulespath in autoinit  Parse
  init/.modulespath like done in initialization script. Call cmdModuleUse for
  each path entry. This way, relative paths are solved before being registered
  in MODULEPATH variable. Now reference counter for MODULESPATH is also set
  when enabling the configured paths.

  * modulecmd.tcl.in: Define empty MODULEPATH/LOADEDMODULES in autoinit  If
  not previously defined, set an empty MODULEPATH and LOADEDMODULES like done
  in init script. Do not source modulerc scripts if MODULEPATH or
  LOADEDMODULES are non-empty.

  * modulecmd.tcl.in: Define autoinit surrounding env vars in
  cmdModuleAutoinit  Rather in renderSettings where only the module command is
  defined depending of current shell. Enables to make use of 'setenv' to
  define surrounding variables like MODULESHOME and call to 'module source'
  before the rendering stage.

  * modulecmd.tcl.in, testsuite/modules.70-maint/120-autoinit.exp: Make
  autoinit shell code fit init script definitions  Use contribution from
  Thomas Zeiser for CSH autoinit code (Thomas Zeiser).

  * modulecmd.tcl.in, testsuite/modules.70-maint/120-autoinit.exp: Produce
  redirect function code on autoinit for sh/fish  Integrate the generation of
  the _moduleraw function on sh-kind and fish shells when calling 'autoinit'
  command.  As for initialization scripts, stderr output redirection is set
  when a terminal is attached to stderr channel. A 'isATty' procedure is
  introduced to detect terminal attachement.

2017-10-17  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * init/bash.in, init/fish.in, init/ksh.in, init/sh.in, init/zsh.in: init:
  redirect stderr msg on stdout if terminal  Change from previous behavior
  where redirection were set if shell was interactive. With this change, a 'sh
  script' command launched from a terminal session will setup module stderr
  redirection whereas previously it was not the case as script was not ran in
  interactive mode.  Shell interactive mode is useful to know that interaction
  will occur on stdin (interesting for completion setup). Knowing session is
  attached to a terminal seems to be the good pivot to adapt stdout or stderr
  functioning (help to determine if PAGER mode can be enabled or not on 'git')

  of alias is reintroduced to switch between main and compatibility version
  based on the state of the MODULE_USE_COMPAT_VERSION environment variable.

  to build compat vers  Introduce '--enable-compat-version' configure argument
  to configure and build compatibility (C) version in addition to main
  version.  This compatibility version is located in the 'compat' directory,
  which is automatically populated with 'c-master' git branch if we work in
  the git repository.  'configure' script is adapted to run the compatibility
  version relative configure script. Unknown command-line arguments are passed
  down to this script, which raise error if these arguments are not known
  there either. Some compatibility version configure script argument are also
  incompatible in this dual installation mode, so an error is raised
  (--enable-versioning for instance).  Build process will generate and install
  modulecmd-compat, module-compat.1 and modulefile-compat.4 from this
  compatibility version. 'compat' suffix enables clear distinction with main
  version files.  Acknowledgment: this development has been made and funded

  load/unload fails  When a modulefile loads or unloads another modulefile,
  load or unload issue did not previously led to upper module load or unload
  failure. As a result, the upper modulefile appeared loaded or unloaded
  whereas its dependent sub-modulefile were not loaded or respectively still
  loaded.  This commit makes cmdModuleLoad and cmdModuleUnload procedure
  return an exit code to let know if load or unload action performed
  correctly. In case of a 'module load' or 'module unload' call within a
  modulefile, the module procedure will raise an error with the dummy message
  'SUB_FAILED'. This message is caught at the result of the modulefile
  interpretation to return an error code, without raising error count or
  message as it has already been handled at the root of the issue.

  occurs in interp mod  Previously an internal error occurring during the
  interpretation of a modulefile (like broken Tcl code) was leading to an
  immediate exit of the whole module execution. So the end of the ongoing
  command was skipped (like printing separator line '---' on display command
  or interpreting next modulefile passed argument on load command).  With this
  change, an internal error occurring during the interpretation of a
  modulefile will be treated as any other error raised by modulefile Tcl
  commands (like prereq, conflict, append-path, etc). Interpretation will be
  considered as failed but ongoing command will get this failed status and
  will continue.  As a result, when this kind of error occurs now display,
  help, load, unload, whatis and source commands will end treatment of the
  failed modulefile and then proceed with the following modulefiles passed as
  arguments.  Add 140-multiargs non-regression tests in 70-maint suite to
  check behavior of module commands running with multiple modulefiles passed
  as argument.

  ERROR' prefix.  To achieve this improvement, modulefile is passed to
  reportInternalBug procedure as a separate argument. Procedures getting and
  manipulating error information have been adapted to add modulefile as an
  element of the error information to be able to transmit it to
  reportInternalBug.  In addition, this commit change error reporting kind
  when facing access error on readModuleContent. Previously access issues were
  reported with reportInternalBug whereas these issues were not relative to
  modulefile content. reportError is now used to report access issue as when
  this kind of error is encountered when checking file is valid modulefile.
  Adapt relative non-regression tests and take opportunity to centralize
  common error messages at start of the testsuite.

  modulefiles  Modulefiles with part of their name starting with a '.' dot
  character are considered as hidden modulefiles, like dot files on Unix-kind
  filesystems. After introduction of the getModules/findModules procedures
  hidden modulefiles where automatically discarded. So this commit
  re-introduce the support to locate these dot modulefiles.  Add a
  'fetch_hidden' argument to the findModules procedure to enable an extra
  lookup on walked directories to gather the dot modulefiles. The getModules
  procedures now looks at the passed mod and if named module correspond to a
  dot modulefile findModules 'fetch_hidden' argument is turned on. Since
  getPathToModule call to getModules for broad search (with just passed mod
  root name), this procedure also makes the 'is hidden module' test to order
  getModules to do the hidden search.  A hidden modulefile does not appear in
  case of wild search, it is only returned when search is about its exact
  name. When a symbolic version targets a hidden modulefile, this modulefile
  will also be returned in case search is about symbol exact name. A module
  alias targeting a hidden modulefile is returned as any other aliases.  Add
  067-hidden non-regression tests in 20-locate suite.

2017-08-27  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Look for alias/sym tgt in all path on cmdModuleSearch
  Introduce a second search round in cmdModuleSearch to solve module alias or
  symbolic version that were not solved by looking at modules in the
  modulepath where they have been defined.  During initial search round across
  modulepaths, these aliases or symbols which return an 'Unable to locate'
  issue from getPathToModule are stored in an extra_search array which gathers
  all elements to look at during the extra search round.  Extra search round
  will attempt to solve these aliases or symbol in all defined modulepaths,
  except the path already looked at.  Due to this second search round, results
  are not processed immediately for each modulepath but once when all location
  searches are finished. So user will get one full output rather progressive
  results modulepath after modulepath. This behavior change in outputing
  results is required as an alias or symbol solved globally may alter the
  result list of a modulepath already processed. So when these kind of alias
  or symbol are searched, their target modulefile will be appended to the list
  of files to interpret of the modulepath they are coming from.  To optimize
  alias/symbol resolution process the 'full_list' array is introduced to store
  all the module names added to each modulepath arrays, so before asking
  getPathToModule for resoltution, look if defined target has not already been
  found and saved in 'full_list'.

2017-08-26  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl.in: Look for alias/sym tgt in all path on cmdModulePaths
  Resolve alias or symbolic version by looking in all modulepaths, rather just
  current modulepath, in order to match alias or symbol targeting a module in
  a different modulepath.  Resolution is made first in current modulepath
  directory, if not solved there the other modulepaths will be looked at
  following their precedence order.  Previously only alias and symbolic
  version targeting module in same modulepath were found.

  * doc/source/modulefile.pod, modulecmd.tcl.in: Handle alias/sym pt. to
  another path in getPathToModule  When searching for a module in a given
  modulepath directory, if a module alias or a symbolic version matches
  searched module but the target of this alias or symbol is not found in
  current modulepath directory, search for this target restarting search from
  the first modulepath in list to ensure modulepath priority.  Previously this
  kind of alias or symbol targeting a module in a different modulepath were
  only found if this path was set after the modulepath where the alias or
  symbol is defined.  Clarify alias and symbolic version modulepath resolution
  steps in modulefile man page.

  is set to 'match' look at matching loaded modules to get result (unload
  behavior). Enable to return the closest loaded modules (not module expressed
  in mod but sharing at least the same root name) by setting look_loaded
  argument to 'close'.  With this change, cmdModuleUnload is adapted to call
  getPathToModule in 'match' look_loaded mode most of the time, but in case of
  'module switch' with a single argument, cmdModuleUnload will call
  getPathToModule in 'close' look_loaded mode.  As a consequence,
  cmdModuleSwitch does not need anymore to work on module resolution and rely

  * modulecmd.tcl.in, testsuite/modules.50-cmds/180-unload.exp: Remove dummy
  code on cmdModuleUnload  Clean code in cmdModuleUnload procedure that were
  used as fallback treatment in case a module loaded were not found by
  getPathToModule (relative modulepath unconfigured?).  Nowadays
  getPathToModule procedure also look at the loaded module information and
  return in case of an 'unload' action registered loaded modulefile, whatever
  configured modulepath.  Take this opportunity to add 180-unload tests in
  50-cmds suite to check unload behavior with different name condition and
  when the modulepath relative to the loaded module to unload is not set
  anymore.

  testsuite/modules.20-locate/038-defcontext.exp: Locate module using loaded
  context only on 'unload'  When searching for a modulefile corresponding to a
  given name, the getPathToModule procedure was previously looking by default
  at the list of loaded modulefiles to find a match. This behavior lead to
  different result depending on the loaded environment context for all module
  commands relying on modulefile location.  For instance, if 'mod' had 2
  versions '1' and '2', the latter being default version, if 'mod/1' were
  loaded it was this version that were answered when asking for 'mod'.  This
  commit restore a predictable and idempotent behavior where the loaded
  modules context is only use when working on this loaded context. Same
  behavior than C-version is now encountered.  As a result, only the 'unload'
  command now looks at loaded modules to find location of modules passed as
  argument. Load, display and help commands do not look anymore at loaded
  modules to locate their module arguments.  Non-regression tests
  038-defcontext in 20-locate have been introduced to ensure correct behavior
  will persist over time.

  be returned.  Adapt non-regression tests in 060-rc of 20-locate suite and in

  command. It was previously possible to match these symbols only if they were
  explicitely defined on a 'module-version' statement and were not about the
  'default' symbol. Symbols inherited by transitivity are now also registered
  in g_moduleVersion and resolution structure by recursive call to

  * modulecmd.tcl: Rework error handling in cmdModuleSearch  Take benefit of
  changes made on getPathToModule to return error information through the
  result list to avoid extra call to getPathToModule in cmdModuleSearch if
  nothing was found.  Now through the parsing of getModules results and
  getPathToModule alias resolution results, all the error information are
  gathered and registered if element name matches search string. At the end of
  the cmdModuleSearch procedure, all the registered errors are printed.  Add a
  'reportIssue' procedure to help reporting error messages depending of their
  kind, useful for getPathToModule and cmdModuleSearch procedures.

  * modulecmd.tcl: Rework registering of access/invalid file error  Integrate
  modulefile or directory access issue or invalidity directly in the result
  array produced by findModules/getModules procedures. By doing so access to

  achieve this integration, the checkValidModule procedure has been revised to
  return any error message in addition to the check status.

2017-07-14  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl, testsuite/modules.20-locate/060-rc.exp: Same res for
  version than alias on getPath/search/paths  Take symbolic version into
  accounts like done for alias when attempting to find out the modulefile
  targeted by a given module name. Symbolic versions were until now left away
  from this resolution treatment as their modulefile target were automatically
  part of the mod_list result returned by getModules procedure. But in some
  cases, a symbolic version may be hold on an alias, so the target modulefile
  of this symbol does not hold the same module name than this symbolic module
  and thus is not part of the result list.  This change is useful for
  resolution procedures like getPathToModule, cmdModuleSearch and
  cmdModulePaths. It also helps to localize the element in error, if any, as
  the availability of the symbolic version information will help to determine
  if the error concerns the search made by the user or not.  Add relative
  non-regression tests in 060-rc of 20-locate suite.

  * modulecmd.tcl, testsuite/modules.20-locate/060-rc.exp: Include global/user
  rc defs in search/whatis/paths  Ask getModules procedure to include global
  or user RC definitions when called in cmdModuleSearch and cmdModulePaths. By
  doing so aliases or symbolic versions defined in these global or user RC
  will be found and solved if specified as module to search on these commands.
  To do so, make 'search' argument of getModules procedure a list rather a
  string to be able to precise multiple search keywords like done by
  cmdModuleSearch.  Add non-regression tests in 060-rc of 20-locate suite.

  * modulecmd.tcl, testsuite/modules.20-locate/050-locrc.exp: Look at loaded
  mods in getPathToModule if asked only  Add 'look_loaded' argument to
  getPathToModule procedure in order to look at the loaded modules to get path
  for specified 'mod' only if this new argument is enabled. 'look_loaded'
  argument is enabled by default.  Disable this behavior when getPathToModule
  recursively call itself to solve aliases or when cmdModuleSearch or
  cmdModulePaths also attempt to solve alias in the middle of their own
  search.  Add non-regression tests in 050-locrc of 20-locate suite.

  * modulecmd.tcl: Constraint module resolution to specific dir if set  If
  'indir' argument is set for getPathToModule procedure, look to find
  modulefile corresponding to 'mod' argument only in modulepath directory
  specified.  Rely on this feature in cmdModuleSearch and cmdModulePaths for

  * modulecmd.tcl: Rework getPathToModule to fully rely on getModules

  * modulecmd.tcl: Rework handling of global/user rc defs in getModules
  Introduce a 'g_rcVersion' array to handle symbolic versions set from a
  global or a user RC the same way than aliases with the 'g_rcAlias' array.
  Then in getModules procedure treat these definitions from global or user RC
  with a 'add_rc_defs' flag. If set and if aliases or symbolic versions match
  passed mod, these aliases or versions from global or user RC are added to
  the result array.  If search in getModules is set to 'rc_defs_included', the
  aliases and symbolic versions set from global or user RC added to the result
  array in addition to the search result from the passed directory.

  * modulecmd.tcl, testsuite/modules.91-sort/020-avail.exp: Register in
  getModules dir default even if broken  Register a default set for a given
  module in the corresponding 'directory' entry in the result consolidated by
  the getModules procedure, even if this default does not correspond to a
  valid entry. This way it is up to the procedure treating the result provided
  by getModules to handle the verification of the default correctness and
  display any error.  As a consequence, a bad default will lead to no result
  displayed for the corresponding module in case of 'onlydefault' avail
  display.  Add tests in 020-avail of 91-sort suite to check behavior.

  * modulecmd.tcl: Register sym versions in getModules result array  Add
  tracking of the source file that defined a given symbolic module version in
  order to add in getModules these symbloc versions to the 'mod_list' result
  array if they match searched modulepath directory and module.  Symbolic
  versions are added to 'mod_list' array as 'version' entries so they can be
  ignored by treatment not requiring them (like display procedures that get
  symbols not independently but through the relative modulefile).

2017-07-09  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Take benefit of new dir handling in getPathToModule  Rework
  code in getPathToModule procedure to use the information that is now stored
  in the mod_list structure (result of the getModules procedure call). With
  this information it is now easier to get directory default element. Also
  empty directories are not part of mod_list result, so less tests are
  required in getPathToModule.

  consolidation  When consolidating directory content information in
  getModules procedure, handle empty directories so they are removed from the
  result array. When an empty directory is removed and its parent directory
  becomes empty after child removal, remove also this directory and so on.
  Moreover when an empty directory is removed and if it was the default
  version of this parent directory, default is changed to last element in
  parent directory.  Add and adapt tests in 020-avail of 91-sort suite.

  * modulecmd.tcl, testsuite/modules.91-sort/020-avail.exp: Rework
  default/latest avail version search  Improve getModules procedure to
  register for each directory the default element in this dir (implicitly or
  explicitly set) and the list of all elements dictionarily sorted.  Then base
  the code in listModules procedure that look for default or latest versions
  only on the information stored in getModules array result rather than
  comparing every result names between each other.  As a side effect, default
  or latest available version printing does not confuse output anymore when at
  a given level a sub-directory element is last element in directory among
  modulefiles. Previously sub-directory was printed but last file among
  modulefiles was also printed (2 latests version at the same level).  Also to
  simplify behavior, and understand a directory tagged "default" does not
  appear anymore in default listing result as its content (the default version
  found in that dir) will be displayed.  Remove stringDictionaryCompare
  procedure that is not used anymore due to the code rework.  Add and adapt
  tests in 020-avail of 91-suite.

  * modulecmd.tcl, testsuite/modules.90-avail/030-multiple.exp: Correct

  source path and search path were similar, aliases were wrongly included in
  results.  Add test in 030-multiple of 90-avail to check correct behavior.

  existence and readability were tested in a single call. To be able to
  distinguish an exist issue from a read issue these two procedures now only
  test existence and readability is tested by the readCollectionContent
  procedure.  As a result, if a collection exists but is not readable a
  different message will now appear.

  re-write by first consolidating new file content in a list variable, then
  when shell init file read is finished and new content is established, the
  shell init file is opened in write mode and its content is replaced with the
  new content.  In addition new behavior only re-writes shell init file if its
  content need to be altered.  Take this opportunity to also change name of
  some local variables to make them shorter.

  to another  When creating interpreter, dump its variable and procedure
  content so before each usage of this interpreter for another modulerc or

  spread of definitions from one interpretation to another.  Variables are
  removed if they are not part of the initial state or restored if their value
  has changed. Procedures are removed if they are not part of the initial
  state. Nothing is done if procedures part of the initial state have been
  changed during an interpretation as there is no vital procedure in this
  list. Interpreter aliases are redefined before each interpretation to clear
  any potential override of these aliased procedures.  dumpInterpState and
  resetInterpState procedures are introduced to handle the dump/reset
  mechanism of the interpreter.  Non regression tests 300-interp in 50-cmds
  suite have been added to test the correct behavior of interpreters when
  running a list of modulerc and modulefiles.

2017-06-06  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Reuse interp rather creating new one each time  Make use of
  the same Tcl interp for each modulefile interpreation and use another one
  for each modulerc (but the same for each modulerc). By doing so we proceed
  like on C-version where same interpreter is used across modulefile or
  modulerc interpretation. Huge performance improvement is achievied with this
  change on commands making intensive use of interp like 'avail'.  Change code
  to use a static name for those interpreter: '__modulefile' for the interp
  dedicated to modulefile interpretation and '__modulerc' for the interp
  dedicated to the RC interpretation.

  * modulecmd.tcl: Workaround 'glob -nocomplain' for perms issue on Tcl8.4  On
  Tcl 8.4, 'glob -nocomplain' also silent permission errors. So to handle
  access issue to directory in findModules we workaround that by not using the
  '-nocomplain' option of glob but handling case where glob raise an error
  when directory is empty.

  * doc/source/diff_with_c-version.pod, modulecmd.tcl,
  testsuite/modules.20-locate/047-symerrs.exp: Revise alias and symbolic
  version internal registering  Register alias and symbolic version deep
  resolution at definition time through a new 'setModuleResolution' procedure
  called by 'module-version' and 'module-alias' procedures. Make use of new
  global array 'g_moduleResolved' and its reverse structure 'g_resolvedHash'
  to keep registered resolution at hand. Also introduce 'g_symbolHash' global
  array to register and easily get the list of all symbols for a given module.
  As resolution is now computed at definition time, the 'getVersAliasList' and
  'resolveModuleVersionOrAlias' procedures can be greatly simplified and just
  need to return the value of the 'g_symbolHash' or 'g_moduleResolved' arrays
  for the module name passed as argument. This change saves lot of time
  especially on commands heavily relying on these procedures like 'avail'.
  The global arrays 'g_versionHash', 'g_moduleDefault' and 'g_aliasHash'
  become useless with this change so they have been removed.  As a side effect
  of resolving alias and symbolic version at definition time, resolution loop
  are not registered anymore and produce an error message when spotted.

  * modulecmd.tcl: Try/catch rather test/try in findModules  When reading the
  content of a modulefile directory, try access then catch any issue rather
  testing access before trying. By doing so we reduce the number of 'access'
  system call. Getting an access error at the 'open' time is a bit more costly
  than at 'stat' time but most modulefile directories should not raise access
  issue, only some.  If any issue occur, register it in the g_access_mod_info
  global array as done in checkValidModule procedure. A unified procedure
  called registerAccessIssue has been setup for both checkValidModule and
  findModules procedures to share same code.

  procedure in target modulefile following same kind of mechanism than 'module
  help'.  If ModulesTest procedure is missing from modulefile, a 'Unable to
  find ModulesTest proc' message is displayed but no error code is set. If
  ModulesTest procedure returns 1 (true), test is considered successful and
  message 'Test result: PASS' is displayed. If ModulesTest returns no or any
  other value, test is considered failed and message 'Test result: FAIL' is
  displayed. In this case, module command exit in error.  Adapt bash and tcsh
  completion scripts for the new command. Describe new command and new mode in
  docs.  Adapt existing non-regression tests and relative test modulefiles for
  new command and new mode in 00-init, 50-cmds and 70-maint suites. Add
  085-test tests in 70-maint to check coherent behavior of new command.

  80-deep suite  Add non-regression tests in 080-access of 80-deep suite to
  guaranty correct behavior when some access issues happen on modulefile or
  modulerc or directory in case of deep modulefiles.

  * modulecmd.tcl: Mention not found alias target in cmdModuleSearch  For a
  given mod search, if an alias corresponds to this search but the associated
  modulefile cannot be located, report locate error on this not found target.

  * modulecmd.tcl: Stop mod dir resolution as soon as we get an issue  When
  looking to a directory content in order to resolve a modulefile in the
  getPathToModule procedure, stop this resolution as soon as we get an issue
  on a mod to return (invalid or access issue).

2017-04-23  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Adapt cmdModuleSearch to raise access error message  If
  searching for a given mod and no modulefile to interpret found, call for a
  resolution of this mod after re-enabling error report. If there are some
  access issues, they will be echoed via this call to getPathToModule.

  * modulecmd.tcl: Add indir arg to getPathToModule proc  Be able to
  optionally precise in what module directory to search for mod instead of
  looking for mod in every directory set in MODULEPATH. If 'indir' arg is set,
  do not raise the 'cannot locate mod' error.  Also build return list with
  module found status when a modulefile cannot be returned. Modulefile is then
  empty string and instead of module name boolean is set depending if a module
  has been found for search or not.

  * modulecmd.tcl, testsuite/modules.70-maint/060-apropos.exp: Display all
  whatis line when search matches one  Instead of displaying only the whatis
  line matching the apropos search, all whatis line are now displayed to get
  the full description of the module.  Add non-regression test in 060-apropos
  of 70-maint suite to check this specific behavior.

  testsuite/modules.91-sort/030-whatis.exp: Match alias but report modulefile
  on whatis/apropos cmds  As whatis/apropos commands make interpretation of
  modulefiles like load/unload, always report the module under their
  modulefile name not their alias name. Of course, alias and symbolic version
  may still be used to query whatis content, but displayed result will mention
  the relative modulefile targetted by this alias or symbol.  Adapt existing
  non-regression tests in 20-locate, 80-deep and 91-sort suites.

2017-04-20  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Plug cmdModuleSearch on getModules rather listModules
  Change cmdModuleSearch procedure to make use of getModules rather calling
  for listModules then running getPathToModule on each result return.  With
  getModules, getPathToModule only need to be called on alias result, not on
  modulefile, which saves a lot of time.

  * modulecmd.tcl, testsuite/modules.50-cmds/190-load.exp: Rely more on
  checkValidModule for full pathname module  Rather checking existence and
  readability within getPathToModule procedure, better rely on the
  checkValidModule procedure then analyse global arrays for error information.

2017-04-19  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Register then display modulefile access issue  When
  checking validity of a modulefile in checkValidModule procedure, register
  any access issue within a new global array g_access_mod_info.  Then when
  looking for a specific module, if an access issue occured during its check,
  display returned error code message.

  * modulecmd.tcl: Check found vers valid before using in getPathToModule
  Last element in a directory may be an alias whose target modulefile may be
  not be readable, so we need to check this target is available on our list of
  valid modulefiles before using it.

  * modulecmd.tcl: Check last elt in dir before use in getPathToModule  Handle
  cases where directory is empty or none of its elements can be accessed.

  20-locate suite  Add non-regression tests in 080-access of 20-locate suite
  to guaranty correct behavior when some access issues happen on modulefile or
  modulerc or directory.  As a loc_rc6/0.9 module is added for the purpose of
  the new tests, adapt non-regression tests working with loc_rc6 in 90-avail
  suite.

  * modulecmd.tcl, testsuite/modulefiles/module/meta,
  testsuite/modules.50-cmds/150-module.exp: Reverse load command mod list on
  unload mode  When mode is set to unload, 'module load' commands in
  modulefile are interpreted as 'module unload' commands. To guaranty correct
  behavior regarding requirements, the module list passed to the load command
  is reversed to get and unload of the modulefiles in the reverse order than
  load.  This is the same behavior than applied on purge or restore commands,
  where loaded module list is reversed to be unloaded.  Add non-regression
  tests in 150-module of 50-cmds suite to check load and unload of meta-module
  works correctly over time.

  * init/modulerc.in, modulecmd.tcl, testsuite/home/rcnomagic,
  testsuite/home/rctosource, testsuite/modules.70-maint/090-source.exp: Relax
  magic cookie constraint on source command  As files sourced by a 'module
  source' command may be managed outside of the modulefile environment, relax
  the constraint of having a specific magic cookie at the start of the file to
  get required clearance before evaluation. This is typicaly helpful for the
  initialization modulerc file that may loose its magic cookie after some
  manual edits.  Add non-regression tests in 090-source of 70-maint suite.

  * INSTALL-win.txt, doc/howto/using_on_windows.pdf, doc/readme.txt,
  windows/module-tcl-win.chm: doc: Transform windows how-to from CHM to PDF
  Change "Using modules-tcl on Windows" how-to document from a CHM format to a
  PDF format, as CHM is a proprietary format that does not cope well with
  open-source project.  Document has been moved to 'doc' directory, a new
  'howto' sub-directory has been created to host this file.

  on display-mode  Introduce a g_inhibit_dispreport global variable to be able
  to inhibit the report of command set within a modulerc file when mode is set
  to 'display'.  This way a 'display' of a modulefile only outputs stuff from
  this modulefile and not from the various .modulerc on the path toward this
  modulefile.  Adapt most display-related non-regression tests to correctly
  check returned output from start to end.

  add the modulefile target of these symbolic version to the result list if
  found in path previously but not yet added to the result list.  With this

  search (elt1/elt2/) sharing same module root.  Add isSameModuleRoot
  procedure on the way to be able to check two modules share the same base
  name.  Add non-regression tests in 020-load and 030-display of 80-deep suite
  to guaranty that sub or upper aliases are correctly found.

  * modulecmd.tcl: Change default search value of listModules to 'wild'
  Previously set default value for 'search' argument was deprecated so change
  it to 'wild' which will result when passed to getModules in the addition of
  a wildcard to look at modules. This way the wildcard is only added in
  conjunction of listModules searches as getPathToModule searches should
  search for exact things.

  * modulecmd.tcl: Move deep mod lookup logic from findModules to getModules
  When a deep module is asked for searched to getModules (elt1/elt2/vers) call
  findModules to search on upper element (elt1) in order to return every
  modulerc or modulefiles related to this module.  Then getModules parses the
  array returned by findModules to build its results with only the
  directories, modulefiles and aliases that correspond to the asked search.
  By doing so, some modulerc search logic can be eliminated from findModules,
  as we will now always look at the whole deep module content.

  * modulecmd.tcl, testsuite/modules.50-cmds/190-load.exp: Rework handling of
  error raised by checkValidModule  In checkValidModule procedure, register an
  entry in a g_invalid_mod_info global array when a modulefile does not
  correctly set the magic cookie. By doing so we are able to state during a
  modulefile search in getPathToModule procedure that the modulefile was found
  but it was not correctly defined.  This mechanism may be extended to other
  kind of modulefile error (like access issues).  Add new non-regression tests
  to 190-load in 50-cmds suite for modulefile specified as full path as new
  error handling better detect issues on this use-case.

2017-04-13  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Optimize getPathToModule when solved alias is sub-mod  In
  case an alias resolution leads to a subsequent modulefile (modulefile part
  of the current searched tree), go further in that searched tree rather
  restarting search with a new getPathToModule call.

  aliases are part of the directory items so it can be returned as the last
  element in it (highest numerically sorted version).  Add tests in 050-locrc
  of 20-locate suite to guaranty this behavior on load command and tests in
  020-avail of 91-sort suite to guaranty this behavior on avail command.

  * modulecmd.tcl, testsuite/modules.70-maint/045-listlong.exp: Consider upper
  dir .version file in findModules  If searched mod is found next to a
  .version file (in same directory), add this rc file to the list of those to
  interpret (like any modulerc files found on the path between the modulepath
  dir and the dir of the search mod).  With this fix 'module list' will
  correctly display the 'default' tag along loaded modules when set via a
  .version file.  Adapt 045-listlong test in 70-maint suite to check this.

  * modulecmd.tcl, testsuite/modules.70-maint/045-listlong.exp: Plug
  cmdModuleList on getModules rather getPathToModule  Call for getPathToModule
  for each loaded modules to retrieve their tag list and modulefile
  modification time in case of long output.  Also fix long output to display
  tag list if any. Add a non-reg test in 045-listlong of 70-maint suite to
  check that.

  * modulecmd.tcl, testsuite/modules.50-cmds/281-info-modulerc.exp,
  testsuite/modules.90-avail/020-single.exp: Plug getPathToModule on
  findModules/getModules  Make getPathToModule procedure relying on
  findModules and getModules procedures for module search and rc file
  interpretation, as listModules now does. findModules and getModules have
  been adapted to also handle getPathToModule use-cases.  Code to look for
  modules is now merged in a common set of procedures which will help both
  search sides (getPathToModule/listModules) to get immediate benefit from
  enhancement made on this code area.  As a side effect a 'module avail' on a
  module name which is an alias will now correctly return this alias module. A
  test has been added in 020-single of 90-avail suite to check that.

  * modulecmd.tcl: Introduce getLoadedModuleFileList proc  Add a
  getLoadedModuleFileList procedure to return a list corresponding to the
  content of the _LMFILES_ environment variable (like getLoadedModuleList for
  LOADEDMODULES).  Take this opportunity to register modulefile path in
  g_loadedModules global array, to be able to easily determine what file
  correspond to what loaded module.

2017-04-01  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl, testsuite/modules.91-sort/020-avail.exp: Separate file
  search from display treatment in listModules  Introduce findModules and
  getModules procedures to handle file search for modulefiles and rc files
  interpretation. findModules is in charge of searching paths for
  module-related files. getModules calls findModules to get file list, then
  interprets any rc files found to consolidate a list of modules to return.
  listModules procedure now calls for getModules to get an array of modules
  corresponding to the directory passed as argument. So focus of listModules
  is now to prepare results for display.  This new methodolidy also corrects
  way directory where handled in case of '--default' and '--latest' listing.
  On a '--default' listing, a modulefile does not appear anymore if a dir is
  set default at the same level. On a '--latest' listing: a dir does not
  appear anymore if set default but not the latest.  Non-regression tests have
  been added in 020-avail of 91-sort suite to ensure a correct behavior will
  be maintained over time.

2017-03-28  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Protect read/close under catch in checkValidModule  Improve
  code of checkValidModule procedure to put read and close calls under catch
  protection. Also, only read 8 characters at the beginning of file to check
  header is valid.

  * modulecmd.tcl: Read then eval rather source module content  Replace source
  of modulefile and modulerc content by a file read then an evaluation of its
  content to optimize open/read/close operations of a 'module avail' command.
  By doing so, a modulerc is only read once during avail rather twice (once
  for validity check, then for sourcing content). Now validity check is
  performed at the same time the content is read to be passed for evaluation.
  In terms of Tcl C code, read+eval is equivalent to source. Only 'info
  script' has to be adapted with read file name in order to get same behavior
  during module code evaluation.

2017-03-26  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Call report only once per list to display

  * modulecmd.tcl: Optimize grid size computation in displayElementList
  Change algorithm strategy to compute the optimized number of column that can
  be used to display in column-fashion a list of elements. Previous algorithm
  was starting with a number of column equals to the number of element in
  list. New algorithm starts closer to the solution with a number of column
  equals to the basic solution where each column width is the same (equals to
  the length of biggest element in list). This approach reduces the number of
  iteration needed to reach best solution.  Also when a column width is
  changed currently computed row widths is adapted only for this column and
  not entirely reset.  All these optimizations drastically improve grid size
  computation time. New algorithm is approximatelly 12 time faster than the
  previous one. There is no more an overhead for this display mode.

  introduce a 'configure' step  Add a 'configure' shell script to generate
  Makefiles, rather than choosing installtion directories or enabled features
  a the 'make' step. By doing so, installation process is clearer and closer
  to build conventions.  Use a custom 'configure' shell script rather than
  using autoconf and automake tool suites in order to keep good readability of
  Makefiles. Moreover our build use case is relatively small since nothing is
  complied so there is no real benefit of using autoconf/automake.  Adapt
  Makefiles to this 'configure' change and add 'distclean' target.

2017-02-25  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * Makefile, init/Makefile: init: add make option to bind on C ver
  .modulespath  Add the 'usecverdotmodulespath' make argument to generate
  init/.modulespath config file as a symlink on C version installed
  .modulespath configuration (by doing so both C and Tcl versions installed on
  the same environment can share the same MODULEPATH initialization setup).
  'cverinitdir' must be known for 'usecverdotmodulespath' to be taken in

  the other version (C or Tcl).  In case a swapped version was defining
  specific PATH or MANPATH entries, these specific entries are removed when

  makefile rules to generate the modulerc and .modulespath configuration
  files. modulerc is generated in any case. By default it hosts the MODULEPATH
  and LOADEDMODULES definition passed to the Makefile with the 'modulepath'
  and 'loadedmodules' argument.  The 'setdotmodulespath' Makefile argument is
  also introduced. When set to 'y', the .modulespath is generated and hosts
  the MODULEPATH definition. In this case, modulerc config file only gets the
  LOADEDMODULES definition or is set empty if no value is passed to the
  'loadedmodules' argument.

  scripts (sh-like, csh-like and fish scripts) if specific option are enabled
  in makefile (enabled by default). With this, bin directory and man directory
  of the modules-tcl installation are prepended to the MANPATH and PATH
  environment variables.  Prepending is required for PATH as manpath utility
  in its default Linux setup will automatically set MANPATH from PATH change,
  so if we want MANPATH to be prepended, PATH has to be prepended.

  installation process  Introduce an 'install' target in makefiles to provide
  an installation process for modules-tcl.  Defines installation paths with
  Makefile variables in order to avoid having a ./configure step. Install
  paths are set during the 'make' step by passing 'prefix', 'libexecdir',
  'mandir', etc arguments to the make command. If no path definitions are
  passed to the 'make' command, installation will be made in
  '/usr/local/modules-tcl' by default.  Installation paths provided (or set
  from the default value found in Makefile) are saved at the 'make' step in a
  .makeinstallpath file. Then at the 'make install' step, this
  .makeinstallpath file is read and make knows where to install modules-tcl.
  These paths definitions are also used to translate *.in init script to their
  installed version.  modulecmd.tcl script is by default set to be installed
  in the libexec directory to follow FHS specification (as this script is an
  executable but not directly accessed by users).

  autoload required  Shell init scripts have been adapted to implement these
  different method to cover most of the initialization cases.  Note that 'zsh'
  requires to declare with autoload the functions put in FPATH directory so
  there is no gain to configure FPATH for 'zsh' compare to a bare source of
  the 'zsh' init script.

  Avail output was showing the aliases holding the symbols instead of the
  modulefile.  getVersAliasList procedure was fixed to perform the alias
  resolution attempt in a second phase of the procedure, to let chance to
  retrieve symbols for the initial module name passed to the procedure.

  for avail/whatis cmds  Do not exit on an error raised by one modulerc or one
  modulefile for global commands avail, whatis or search that parse the
  content of all modulefile/modulerc found in the defined module paths.  By
  doing so results from these global commands will not be harmed if error
  exists in a few modulefiles. The content of these modulefiles will be
  ignored after the erroneous line. So in a whatis/search case if the
  module-whatis definition is set before the erroneous line, the modulefile
  will be taken into account. If the module-whatis definition is set after the
  erroneous line, the modulefile will be ignored.  To achieve this goal a
  'exit_on_error' argument has been added to the 'execute-modulerc' and
  'execute-modulefile' procedures. By default this argument is enabled but
  calls made from 'listModules' and 'cmdModuleSearch' disable it.  Add
  non-regression test to 055-whatis and 060-apropos in 70-maint suite and to

  interpreting a modulefile or a modulerc from execute-modulefile or
  execute-modulerc procedures, exit as done elsewhere. Means call for error
  code rendering and raise error to top level, where exit command is called.
  A new procedure called 'exitOnError' is added and it is called by
  execute-modulefile and execute-modulerc procedures. Top level error
  management code now does not always print an error message as in this
  situation error message has already been displayed when the
  reportInternalBug procedure was called.  Add non-regression tests to
  190-load in 50-cmds suite and to 070-display and 080-help in 70-maint suite.

  * modulecmd.tcl: Refactor exit and ModulesVersion set of execute-modulerc
  Refactor the execute-modulerc procedure to handle exit in case of critical
  error as it is done on execute-modulefile procedure with the slave interp
  evaluation returning an errorVal. Then this errorVal is treated to check if
  a critical error as been encountered (errorVal=2).  To achieve this goal the
  way the ModulesVersion variable is set need to be changed as the slave
  interp now returns errorVal not ModulesVersion. A setModulesVersion
  procedure is added to enable the slave interp to pass the value of the
  ModulesVersion variable in the master interp context.

  * modulecmd.tcl: Retrieve help mode from module-info on execute-modulefile
  Remove the 'help' argument on the execute-modulefile procedure that was used
  to know the execution is made on a 'help' mode. Now that 'help' mode is
  pushed to the 'mode' stack, 'help' mode can be retrieved from 'module-info
  mode'.

  * modulecmd.tcl: Inhibit non-critical error report on avail/whatis
  Introduce the g_inhibit_errreport variable to inhibit the stderr display of
  non-critical error aka error reported through the reportWarning, reportError
  or reportInternalBug procedures.  inhibitErrorReport and reenableErrorReport
  procedures are added to enable or disable g_inhibit_errreport.  This new
  mechanism has been deployed on the 'avail', 'aliases' and 'whatis/search'
  commands, in order to avoid error flood when parsing all modulefiles or
  modulercs. This way, results from these commands will appear clearly to the
  user.

  * modulecmd.tcl, testsuite/modules.50-cmds/210-exit.exp: Handle multiple

  module-whatis text-line is appended to the previous lines.  In case of
  search, these lines are displayed only if they match the search pattern (to
  get same behavior as on C-version)  As a side effect, if no 'module-whatis'
  directive are found in a modulefile, this modulefile is never displayed on a
  'module whatis' call (same behavior as on C-version).  Adapt 210-exit whatis
  test in 50-cmds suite.

  * modulecmd.tcl: Handle multiple args passed to module-whatis cmd  When
  multiple arguments are provided to the module-whatis module command, join
  them with " " to get a line of text.

  * modulecmd.tcl: Return error on whatis if searched modfile not found  If
  'module whatis' command gets modulefiles as argument, if this or these
  modulefiles do not match any existing modulefile in the defined module path,
  then raise error as done on 'module load'.

  when used as path element in var  Some list variable may contain element
  with ':' in it, like for URL, separated by a character different than ':'.
  However corresponding modshare variable always use colon character as
  separator so we need to escape colon used as variable content in modshare
  variable to avoid issue.  To achieve that psplit and pjoin procedures are
  introduced as well as a charUnescaped procedure, which is the reverse of the
  already existing charEscaped procedure. With these new procedures path-like
  variable escape or unescape $g_def_separator character used in element of
  the variable when splitting or joining the whole variable.  Adapt
  042-append-delim, 047-app-del-undo, 052-prepend-delim and 057-pre-del-undo
  tests in 50-cmds suite to check colon character is correctly escaped in
  modshare variable.

  * modulecmd.tcl: Introduce charEscaped proc to escape char passed as arg
  Replace multiEscaped, doubleQuoteEscaped and singleQuoteEscaped procs by a
  single procedure that can escape any set of characters passed as argument.

2016-12-27  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Make 'switch' command consistent  Switch command were
  previsouly setting 'new' as 'old' and 'old' as 'new' when 'new' is detected
  loaded. This behavior led to inconsistency especially when the same 'module
  switch old new' command is called twice. First time 'old' is loaded and
  'new' is unloaded. Then for the second call 'old' is unloaded and 'new' is
  loaded, and so on. In this case, the result of the switch command depends on
  the current situation which confuses most persons using it.  This commit
  makes the switch command idempotent by always ending up with 'old' unloaded
  and 'new' loaded, whatever the starting situation is.

  * modulecmd.tcl, notdone/modules.50-cmds/210-exit.exp,
  testsuite/modules.50-cmds/210-exit.exp: Add support for 'exit' command in
  modulefile  Add support for use of 'exit' command within modulefile as
  described in modulefile(4) man page. This command will cause the immediate
  cessation of this module and any additional ones on the command line. This
  module and the subsequent modules will not be listed as loaded. No
  environment commands will be performed in the current module.  To achieve
  that a 'exitModfileCmd' procedure is added to superseed the 'exit' command
  during modulefile interpretation. When called this procedure sets a flag
  that inhibit further modulefile interpretation.  Import and adapt 210-exit
  tests in 50-cmds suite.

  'reload' command  Add a 'refresh' command as available on C-version but
  instead of reloading the volatile components (ie. shell aliases) only, here
  we unload then reload all the currently loaded modules. This behavior is
  different than on C-version but it ends with same results : shell aliases
  are refreshed in sub-shells.  Import and adapt 07-refresh tests in 50-cmds
  suite.

  module-log, module-trace, module-user and module-verbosity commands
  available on C-version. These commands do not seem relevant to be
  implemented on Tcl-version of module, but having dummy procedure for them
  enable support for modulefiles using these commands. Without dummy
  procedures these modulefiles raise error as the commands are not known.  The
  4 dummy procedures report a warning message to let the user know that even
  if the modulefile has been loaded/unloaded/etc, the module-log,
  module-trace, module-user or module-verbosity calls were not interpreted.

  * modulecmd.tcl, testsuite/modules.50-cmds/140-system.exp: Adapt 'system' to
  behave like described on manpage  Previously the 'system' modulefile command
  was adding the specified string to the list of things to interpret on
  stdout. This commit aligns the behavior of the 'system' command on the one
  implemented on Modules C-version which is documented on modulefile(4) man
  page.  Now 'system' passes string to the 'exec' Tcl procedure with stdout
  redirected to stderr since stdout would be parsed by the evaluating shell.
  The exit status of the executed command is returned.  Adapt '140-system'
  test in 50-cmds suite accordingly.

  Fix 'module list' when module loaded with full path  On Tcl-version,
  modulefile loaded by giving its full path has its name equal to its full
  path since module name and version cannot be distinguished from the path. On
  C-version, module name equals to the tail of the full path.  Also import and

  * modulecmd.tcl: Disable g_force to avoid loading already loaded mod  In
  order to get closer to C-version, disable g_force by default to avoid
  loading a modulefile already loaded. This behavior also avoid path element
  reference counting to get increased when the same module is asked twice for
  load.  Thus with cleaner path element reference count, automatic modulefile
  dependency management is made possible.

  Then adapt listModules procedure to be able to display only the aliases
  defined from the global or user modulerc (no directory lookup) when search
  argument is set to "rc_alias_only".  cmdModuleAvail now starts by displaying

  * modulecmd.tcl, testsuite/modules.90-avail/050-long.exp: Include aliases as

  results returned all the module aliases defined through the analyzed
  directory. By doing so a module avail or search commands automatically
  return all the aliases defined in addition to regular modulefiles to get a
  complete view of what is available.  In module-alias procedure the full path
  name of the file that declared an alias is registered in a g_sourceAlias
  array. In listModules this array is looked at to distinguish the aliases
  coming from the currently analyzed directory.  Aliases are displayed from
  the module path where they are defined. A "@" symbol is appended to the
  alias name, in the same way module-version are displayed, in order to be
  able to distinguish an alias from a regular modulefile. "@" has been
  retained as symbol to qualify module aliases as this symbol is used by "ls"
  command to qualify symbolic links.  When --long display format is asked, the
  target of the alias is printed after the alias name. No last modification
  time is displayed as it has no meaning for a module alias.

  * modulecmd.tcl: Fix default module test based on '(default)' tag  As
  default tag may not be the only one tag applying to a module (other versions
  may also be part of the tag list), default version tests, that were only
  comparing the '(default)' string, have been adapted to correctly handle
  cases where multiple tags apply to a default module.  On
  resolveModuleVersionOrAlias procedure, test on '(default)' string has simply
  been removed since name passed to the procedure does not contain anymore
  tags in any situation.  On getSimplifiedLoadedModuleList procedure, call to
  listModules procedure has been revised to only ask for default versions,
  this way there is no need to test a '(default)' string since all results
  returned are default versions.

  * modulecmd.tcl, testsuite/modules.90-avail/050-long.exp: Handle
  show_modtimes directly in listModules  Adapt cmdModuleAvail and listModules
  procedures to handle show_modtimes treatment directly within listModules
  rather than in cmdModuleAvail. This way there is no need to loop over
  listModules results and call getPathToModule on each of them. File location
  is already known by listModules, so file modification time query is easy to
  make there.  As a consequence avail long output is directly managed by
  listModules. This output structure has been improved to let more space to
  display module tag list. Moreover when terse mode is used, tag list is no
  more separated by a space from module name (same behavior as C-version).
  Align list and savelist long output the improved output structure applied to
  avail long output.

  * modulecmd.tcl: Make listModules show_flags even when filter set  Previous
  listModules code was not complying with the show_flags directives when a
  filter were set like "onlydefaults" or "onlylastest". This commit improves
  this by centralizing the code handling the show_flags directives.

  * modulecmd.tcl: Merge listModules proc flag_default_* args  Simplify
  management of flag_default_dir and flag_default_mf arguments of listModules
  procedure by merging both args in a show_flags argument and set local value
  for reporting flags of directories or modulefiles based on the value of this
  show_flags argument and global variables flag_default_dir and
  flag_default_mf.

  * modulecmd.tcl: Remove listModules proc full_path argument  Simplify
  listModules procedure by removing the full_path argument that was in all
  cases disabled.

  cookie or a not found errors when processing name passed as argument.

2016-09-22  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Fix module-info symbols resolution  Return all symbols
  defined by calling the getVersAliasList procedure.  This procedure has been
  enhanced to first attempt an alias resolution on the name passed to it. Then
  each time a version or a default is found a recursive call is made on this
  new name to get all versions or default linked to the initial name.
  getVersAliasList has also been enhanced to pass and get a list of already
  resolved symbols for the current resolution in order to detect infinite
  resolution loop.  Results returned by getVersAliasList are now sorted using
  the dictionnary-style sort as already performed by listModules.  All these
  improvements made to the getVersAliasList will benefit to the listModules
  procedure so "avail" command will return more accurate versions and default
  information.

2016-09-13  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Improve .modulerc/.version handling in getPathToModule
  Adapt getPathToModule to parse .modulerc file at each level of the specified
  module in order to be able to resolve any alias that may be defined within
  the module directories. Means if module name "mod/sub1/sub2" is passed to
  getPathToModule, the procedure will parse any .modulerc file in "mod",
  "mod/sub1" and "mod/sub1/sub2" directories (if these dirs exist) then it
  will attempt to resolve module name with aliases and version found.  To
  behave like Modules-C, if both a .modulerc and a .version file exist for the
  module name passed to getPathToModule, .modulerc is parsed then .version. In
  this situation a default value set from .version will win over a default
  value set in .modulerc. Same kind of change has been applied to the
  listModules procedure.  A new argument named "search" has been added to the
  listModules procedure to be able when called by getPathToModule with a
  "no_depth" value to only get the content of a directory and not its sub
  elements as sub-directory resolution, .modulerc and .version are handled
  within getPathToModule.

  * modulecmd.tcl: Fix module-info version resolution  Call for
  resolveModuleVersionOrAlias procedure to deeply resolve name provided by
  recursively looking at alias or version structures.  Also improve
  module-version procedure to raise a warning message in case of duplicate
  version symbol is found.

2016-09-09  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Fix module-info alias resolution  Call for
  resolveModuleVersionOrAlias procedure to deeply resolve name provided by
  recursively looking at alias structures.  Improvement is made here to the
  resolveModuleVersionOrAlias procedure in order to be able to only look for
  alias (and not alias and version) when attempting resolution.  A g_aliasHash
  array is introduced here to be able to reversely look at alias definition as
  Modules-C does. module-alias procedure has been adapted to fill this new
  structure and resolveModuleVersionOrAlias makes use of it if alias is
  searched and not found in g_moduleAlias array.

2016-09-11  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Register alias and version by the short module name  Store
  aliases and versions by the short module name rather than full module path
  to get closer to the Modules-C behavior on alias and version management. As
  a consequence an alias defined in a module path can apply to a module stored
  in another module path. But this behavior is required to make alias defined
  in global modulerc functional.  A getModuleNameVersion procedure is
  introduced to determine with a name provided as argument the corresponding
  module name, version and name/version. Module name is guessed from current
  module name when shorthand version notation is used. Both name and version
  are guessed from current module if name provided is empty.

2016-09-22  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Improve resolveModuleVersionOrAlias proc to detect loop
  Adapt resolveModuleVersionOrAlias procedure to resolve only one name at a
  time and pass a list of already resolved symbols for the current resolution
  in order to detect infinite resolution loop.  When infinite resolution loop
  is detected error message is raised and returned value is set to "*undef*"
  to behave like Modules C-version.

2016-09-19  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Remove useless alias/version resolution in module proc
  Aliases and versions are solved when getPathToModule proc is called and
  getPathToModule is called by all command proc that need to resolve an alias
  or a version.  So alias and version resolution is not required at the
  beginning of the module procedure. Resolving any argument to the module
  procedure as alias or version was also potentially erroneous.

2016-09-17  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Source $MODULERCFILE/modulerc when $MODULERCFILE is dir  In
  order to behave like C-version, if the $MODULERCFILE variable is set and
  points to a directory, source the "modulerc" file in it instead of trying to
  source the directory (which led to error).

  * modulecmd.tcl, testsuite/modules.00-init/071-args.exp: Check each command

  * modulecmd.tcl, testsuite/modules.90-avail/020-single.exp: Improve
  column-mode in displayElementList  Change way to compute rows*cols display
  grid in order to maximize the number of column to display per line. To do so
  a width is computed for each column instead of having each column width
  based on the largest one.  The new code takes a bit more time to proceed (as
  there is more stuff to compute) but the additionnal time taken is not really
  discernable from the user perspective: on a 'module avail' containing ~10
  paths and ~400 modulefiles, there is less than 0.1 second extra time.  As
  display is now denser, two spaces are now used instead of one to separate
  elements.  Thanks to Aurelien Degremont for crafting the right algorithm for
  this.

  * modulecmd.tcl, testsuite/modules.91-sort/030-whatis.exp: Merge list
  printing codes under displayElementList  Set a common procedure to manage
  the display of list of elements: displayElementList. Lists can be displayed
  in a column fashion or with only one element per line. Elements displayed
  may be prefixed by their number. Also a header can be printed on top of the
  list.  Adapt cmdModuleList, cmdModuleSavelist, cmdModuleSearch,
  cmdModuleAvail and cmdModuleAliases to use this new procedure.  With a
  single set of code to manage this aspect it will be easier to improve it and
  all commands calling it will automatically benefit from these improvements.

  testsuite/modules.00-init/090-switches.exp: Put all command-line parsing
  under catch protection  Make command-line option parsing benefit from the
  catch (+reportError +exit 1) applied to command parsing and running. This
  way it produces same kind of error behavior when an invalid option is typed
  as when an invalid command is typed.  Also put shell name parsing first in
  order to be able to renderError appropriately when an invalid option is
  typed. Elsewhere the puts of /bin/false on stdout was not made as no shell
  were set.  An invalid option containing only one '-' as first character will
  now also produces an error. Before that only invalid options starting with
  '--' were treated as error.  Improve testsuite on option treatment. Test
  long and short versions of these options and test the returned output.

  * modulecmd.tcl, testsuite/modules.00-init/070-command.exp,
  testsuite/modules.00-init/090-switches.exp: Merge main command handling in
  module proc  Make module command handling appear in a single location, the
  module procedure, rather than having a duplication of code in the main
  section.  This modification simplifies the addition of new commands or the
  adaptation of existing commands as everything has to be done only once.  Now
  calling module from a modulefile or a modulerc benefits from the same
  command shortcuts than when it is called from the command line.  Moreover do
  not print anymore the module usage message when an invalid command is typed,
  as this large message often hide the error printed on the first line. An
  advice to type "module --help" is printed instead.

  * modulecmd.tcl: Simplify parsing of command switch arguments

  * modulecmd.tcl: Harmonize usage of exit when error occurs  When error
  occurs and exit is called, always quit with the same error code: 1.  Add a
  call to "exit 1" when error is caught in main section when processing module
  command.  Remove use of exit in cmdModuleInit procedure, replaced by call to
  reportErrorAndExit, which will be caught at top level and go through the
  "exit 1" added above.  End main section with an "exit 0" to explicit
  everything went well.

  * modulecmd.tcl: Harmonize reportErrorAndExit messages  As done for the
  other report* procedures, here we harmonize some reportErrorAndExit messages
  to something simpler and clearer.  There is no need to make
  reportErrorAndExit call to reportError instead of using "error" build-in
  proc since error proc raise a message which is caught and output by
  reportError in the end.

  * modulecmd.tcl: Standardize reportWarning procedure  Adapt reportWarning

  * modulecmd.tcl, testsuite/modules.00-init/030-shells.exp: Introduce
  getModulePathList proc  Defines a getModulePathList procedure that returns a
  list of the module paths by parsing the MODULEPATH environment variable.
  This new procedure enables to gather in a single location the code to parse
  MODULEPATH, thus it removes the need for many procedures to know about "env"
  and "g_def_separator" global variables.  getModulePathList procedure also
  enables with its "behavior" parameter to directly exit on error when
  MODULEPATH is not set. By default, it returns an empty list. The
  "exiterronundef" behavior allows to closely match previous behavior, when
  $env(MODULEPATH) were accessed without being defined.

  * modulecmd.tcl: Introduce getLoadedModuleList proc  Defines a
  getLoadedModuleList procedure that returns a list of the loaded modules by
  parsing the LOADEDMODULES environment variable.  This new procedure enables

  removes the need for many procedures to know about "env" and
  "g_def_separator" global variables.

  * modulecmd.tcl: Remove separator optional parameter where useless  An
  optional parameter named "separator" was specified on many procedures but
  calls to these procedures never set this parameter. This commit removes

  state.

  concept  Collection directory may sometimes be shared on multiple machines
  which may use different modules setup. For instance modules users may access
  with the same HOME directory multiple systems using different OS versions.
  When it happens a collection made on machine 1 may be erroneous on machine
  2.  To handle this use case, we introduce here the concept of target for
  module collections. By setting the MODULES_COLLECTION_TARGET environment
  variable to something that can make a distinction between machines that are
  incompatible with each other, only collections matching this target will be
  valid on it.  When a target is set, only the collections made for that
  target will be available to restore, list, show, rm, and saving will
  register the target footprint (collection filename will be suffixed with
  ".$env(MODULES_COLLECTION_TARGET)". Collection target is not involved when
  collection is specified as file path on show, restore and save commands.
  For example, the MODULES_COLLECTION_TARGET variable may be set with results
  from commands like lsb_release, hostname, dnsdomainname, etc.

  * testsuite/home/.Xresources, testsuite/modulefiles/x-resource/1,
  testsuite/modules.50-cmds/250-x-resource.exp: testsuite: add tests and
  relative configs for x-resource  Add 250-x-resource tests in 50-cmds serie
  to check x-resource commands in modulefile are correctly interpreted at load
  and unload times for the various shells.  A x-resource/1 modulefile and a
  .Xresources config files are added to test various setting conditions
  (single resource string, complex string content, resource file to load).

  * modulecmd.tcl: Implement unload of x-resources and fix load  Implement
  unload action of x-resources defined for all shells. Unload of x-resources
  is done by clearing string resource values with "xrdb -merge" since there is
  no xrdb command that can clear one property (xrdb -remove clears
  everything). For resources loaded from file, file content is parsed with
  "xrdb -load" and each property it defines is also cleared.  This commit also
  corrects the way x-resource value is parsed. Sometimes x-resource value may
  be provided within resource name as the "x-resource {Ileaf.popup.saveUnder:
  True}" example provided in manpage. So if no value is provided, resource
  name is looked at to check if a value is provided within string (space or
  colon are looked at).  Load of x-resources is also fixed by this commit for
  sh, csh and tcl to handle resource name and value containing wildcard
  characters and fixed for sh and csh to output well-behaving code to execute
  ("echo | xrdb -merge" instead of "xrdb -merge <<EOF")

2016-07-22  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * init/python.in, modulecmd.tcl: Fix Python autoinit, error and x-resource
  rendering  Python code used to define the module command (autoinit action)
  was broken (syntax errors) and not Python3-compatible. Error rendering is
  also fixed here for Python3 compliance. Code used to process x-resource is
  adapted to comply with Python recommendation [1] (subprocess.Popen should be
  used instead of os.popen).  Python init script is also modified by this
  commit to use same code as the one generated by autoinit action with call to
  subprocess.Popen rather than os.popen.  [1]

  * modulecmd.tcl: Replace reverseList proc by lreverse build-in proc
  lreverse build-in procedure has been introduced in Tcl8.5 and provides best
  performances. For compatibility with Tcl8.4 and earlier, a lreverse
  procedure is provided here (set if not defined). See [1] for an overview of
  lreverse implementations and performances.  [1] http://wiki.tcl.tk/17188

2016-07-17  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Use 'eq'/'ne' in place of '=='/'!=' to compare strings
  '==' and '!=' operators are meant for numerical comparison so it is more
  correct and faster to use 'eq' or 'ne' operators when comparing strings.
  This was found using the 'ttclcheck' utility [1] over the modulecmd.tcl
  complete code.  [1] http://www.xdobry.de/ttclcheck

2016-07-15  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Remove code regarding undefined g_aliasHash array  Some
  code where present in module-alias proc regarding a g_aliasHash global
  array. But this array variable is not defined nor used anywhere else in
  script.

  * modulecmd.tcl: Remove unused spaceEscaped proc

2016-07-14  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Introduce reportDebug proc  Add a reportDebug procedure to
  simplify and harmonize debug report management. With this new procedure, the
  way to test if debug is enabled or not is found only in one place (and
  g_debug variable does not have to be known in every procedures).

  * testsuite/modules.50-cmds/140-system.exp,
  testsuite/modules.95-version/040-xgetenv.exp: testsuite: comment
  cmds/140-system and version/040-xgetenv  Skip both cmds/140-system and
  version/040-xgetenv tests since pure-Tcl version of module does not behave
  like C version for "system" procedure and "live" resolution of variables set
  within paths.

2016-07-13  Xavier Delaruelle <xavier.delaruelle@cea.fr>

  * modulecmd.tcl: Add hints for vim to correctly set tabs when developping

  * Makefile, testsuite/config/unix.exp: testsuite: fix MODULECMD
  initialization  Update way MODULECMD is defined to let a chance for
  modulecmd.tcl to be found before looking at PATH for modulecmd binary. This
  way on systems where modulecmd is installed in default paths, tests can
  still be run on modulecmd.tcl.  Remove MODULECMD env variable setup in
  Makefile for "make test" since environment variables are not looked at to
  initialize MODULECMD tcl variable when tests are configured.

  testsuite/modules.91-sort/999-cleanup.exp: Always dictionary-sort list of
  modules or collections  Dictionary sort of Tcl enables to determine that a
  version 1.10 is greater that a version 1.8, for instance. This useful kind
  of sort was in use in modules-tcl previously but not for every sort. For
  instance load command was correctly able to find the greatest version of a
  module whereas avail and whatis commands did not sort existing versions
  accordingly.  This patch applies the dictionary sort everywhere to ensure
  the exact same sort is applied everywhere. Dictionary sort appears to be the
  most appropriate kind of sort to work with software versions. So the
  sort_order argument of listModules procedure is removed to always get the
  same sort applied. Also a stringDictionaryCompare procedure is added in
  order to compare two strings with dictionary-sort (useful to know what
  string is greater than the other).  In addition, modules.91-sort testsuite
  is introduced to guaranty that avail, whatis and load commands behave
  appropriately regarding sort.

  the way pre-commit's work.  (It's making the change for the next commit not
  the current one).

  * modulecmd.tcl: Fixed a typo.  I introduced a typo in the last commit this
  fixes it.

  * modulecmd.tcl: Fix up the formating a little.

  * init/bash_completion: Another patch from Xavier Delaruelle,  Tweak to the
  bash completion so it works around some extra spacing.

  * init/csh.in, init/tcsh.in, init/tcsh_completion: Another patch by Xavier
  Delaruelle,  This one reworks the patch from Joshua Randall to define tcsh
  completion for the c version so it works with this one.

  * init/bash_completion, modulecmd.tcl: More patches from Xavier Delaruelle,
  Added -D option (short form of --debug) Added -d or --default to only show
  default modules when doing module avail Added -L or --latest to only show
  latest version of modules when doing avail

  * init/bash.in, init/ksh.in, init/sh.in, init/zsh.in: Patch from Xavier
  Delaruelle,  Now only redirect module from stderr to stdout in interactive
  mode to avoid breaking non interactive sessions (scp, sftp, etc).

  * init/bash_completion, modulecmd.tcl: 3 patches from Xavier Delaruelle  Add
  --long and --terse options to help. Fix ModulesDisplay so it works. Fix
  ModulesAlias function so it works as well.

  * init/tcsh.in: Fix a site specific bit that snuck in awhile back.  This
  shouldn't have been here, now it is fixed though.

  * init/bash.in: source the bash_completion script by default.  This is for
  the tcl native version of modules and it just starts using the
  bash_completion script that has been supplied so that it's actually used.

  Added really old man pages, and a bunch of example things. Still need to
  write some documentation for the contrib stuff and update the man pages.

  * LICENSE.GPL => doc/LICENSE.GPL, LICENSE.LGPL => doc/LICENSE.LGPL,
  README-EMACS.txt => doc/emacs.txt, README.txt => doc/install,
  doc/installwin.txt, readme.txt: Setup some more complicated documentation
  and move existing docs to new dir.

  modules. There is still lots of work to be done but there are a good number
  of tests that are working. Currently 80 of 90 are passing. At this point I
  want to commit before fixing issues which involve modifying the main
  application.  Kent

  * tcl/modulecmd.tcl: This commit does a couple of things. Bring back the
  auto determine shell to call(needed for the next commit testsuite) It also
  removes the need for using a temp file This commit also has a couple of
  small fixes to make it more like the standard version of modules as far as
  output to the screen goes.  Kent

  * tcl/modulecmd.tcl: This commit does a few things to modulecmd.tcl  It
  cleans up some unused global vars Fixes some spacing in some report
  statements as well as fixes some debugging statements adds a ubuntu specific
  bit of code to uname so uname release returns the codename of an ubuntu
  install  Finally in getPathToModule I commented out the Check for aliases
  bit of code This is already done at the top level so no need to do it again.
  (If someone finds a case where this is needed let me know and I'll add it
  back in)  Kent

  * tcl/modulecmd.tcl: Last patch from Gerrit Renker  This one makes it so
  module switch tries to swap the order if the user messed it up. If you type:
  module switch new old instead of: module switch old new it will attempt to
  correct it.  Kent

  * tcl/modulecmd.tcl: Another patch by Gerrit Renker This one makes module
  display/show more similar to the c version of modules.  Kent

  * tcl/modulecmd.tcl: Two more patches by Gerrit Renker These two clean up
  the "version" info and makes the startup files more compatable with the c
  version of modules.  Kent

  * tcl/modulecmd.tcl: This is patch #6 from Gerrit Renker This patch
  increased the CSH_LIMIT to the same as linux's default. (This seams
  reasonable, if people have older machines that have issues they can always
  drop it back down to a lower value)  Kent

  * tcl/modulecmd.tcl: This is patch #5 from Gerrit Renker This one improves
  escaping of special symbols  Kent

  * tcl/modulecmd.tcl: Patch #4 from Gerrit Renker This one cleans up dynamic
  columns and makes it autodetect  Kent

  * tcl/modulecmd.tcl: small typo in last patch was missing a $  Kent

  * tcl/modulecmd.tcl: Patch #3 submitted by Gerrit Renker This one fixes a
  heck of a lot of typo's. (Spelling isn't my strong suit) :)  Kent

  * tcl/modulecmd.tcl: Two patches by Gerrit Renker  The first one fixes an
  issue with sourcing a .versin/.modulerc over and over the second one fixes
  up listModules so that it behaves better. (Gerrit has submitted a number of
  patches, this is just two of them)  Kent

2010-05-24  sirdude <sirdude>

  * tcl/modulecmd.tcl: This is a patch by Gerrit Renker to fix an issue with
  _LMFILES_ not having correct data when nesting module load/unload commands

  Passes all tests but 2 generate "duplicate version symbol ... found". Merged

2009-04-09  sirdude <sirdude>

  * tcl/modulecmd.tcl: This is a patch by John Tseng,  It adds the ability to
  support Dynamic columns using stty you just setenv DYNAMIC_COLUMNS 1 and it
  will start using them.  Kent

  * tcl/modulecmd.tcl: Fleshed out the debugging statements so most functions
  have them now.  Kent

2009-02-24  sirdude <sirdude>

  * tcl/modulecmd.tcl: Some more cruft removal.  Kent

  * tcl/Makefile, tcl/init/modulerc, tcl/modulecmd.tcl: added synonym of
  search for apropos/keyword Partialy contributed by Hunter Matthews.  There
  is still an issue with it though.  If you have a malformed module it will
  die.  Probably there are other commands that die as well.  Need to look at
  it more.  Kent

  * tcl/modulecmd.tcl: Cleaned up some stuff that wasn't used and also fixed
  some minor formating issues.  Kent

  * tcl/modulecmd.tcl: Updated the help dialog so its a bit more organized an
  easier to read.  Kent

  * tcl/modulecmd.tcl: Patch by Hunter Matthews to clean up the output of
  module avail a little bit.  Kent

  * tcl/modulecmd.tcl: Some patches submitted by Hunter Matthews  adds --help
  as a commandline option. fixes issues with modulerc file getting sourced
  twice in sh and tcsh shells.  Kent

2008-09-17  sirdude <sirdude>

  Thanks to John Tseng.  Kent

2007-09-05  sirdude <sirdude>

  * tcl/modulecmd.tcl: Made it so that module use and module unuse work the
  same way, I also added a little debugging info for both of them.  Kent

2007-05-16  sirdude <sirdude>

  * tcl/modulecmd.tcl: update to replaceFromList  patch from Olly. adds a fix
  for when item2 is empty.  Kent

  * tcl/modulecmd.tcl: Another great little patch by Olly Stephens,  This one
  makes it so that if a module has an error message in it module help
  (modulefile) will still attempt to call the help function for that module.
  Kent

  * tcl/modulecmd.tcl: Another patch by Olly,  This one extends some of the
  shortcuts accepted. example module lo blah   now works just like module load
  blah Its not perfect but again better than what is there currently.  Kent

  * tcl/modulecmd.tcl: Another patch by Olly,  This one makes it so that help
  is displayed if a user types an invalid module command (Example: module
  blah)  or if a user just types module with no args.  Kent

  * tcl/modulecmd.tcl: Patch by Olly,  Forces 0600 mode on the tmpfile when
  opening it. Really we need to figure out how to remove the need for a
  tmpfile, until then though this is still better than it was.  Kent

2006-12-19  sirdude <sirdude>

  * tcl/modulecmd.tcl: updated module list so it skips modules with no name
  for -l and -t (it now handles them like module list without options)  Kent

2006-12-13  sirdude <sirdude>

  * tcl/modulecmd.tcl: Fix provied by Eric Mastromarc reference counting was
  not working for unload-path now it is again.  Kent

2006-12-12  sirdude <sirdude>

  * tcl/modulecmd.tcl: Modified prereq so its a logical OR for multiple
  modulefies on one command line.  example: prereq foo bar If you want it foo
  AND bar do: prereq foo prereq bar  Patch done by Chris Pruett  Kent

2006-12-07  sirdude <sirdude>

  * tcl/modulecmd.tcl: Patch provided by  Thomas Zeiser,  better fix for
  reverting header to find dynamically what version of tclsh to use.  It also
  now sorts output of module avail.  Kent

  * tcl/modulecmd.tcl: reverting commit 1.75 where I removed the header
  section that finds tclsh.  Kent

2006-09-13  sirdude <sirdude>

  * tcl/modulecmd.tcl: Changed (VAR)_modshare back to use g_def_seperator
  instead of user defined variable.  Currently there is an issue with doing
  something like append-path -delem " " PATH /usr/bin append-path -delem " "
  PATH /usr/local/bin append-path -delem ":" PATH /usr/sbin  then loading that
  module and unloading it... Because of the mixed delimiters the unload does
  not work properly. It at least works for the basic case now though.  Kent

2006-09-07  sirdude <sirdude>

  * tcl/modulecmd.tcl: changed syntax of specifying a delimitor to match c
  version of modules and also made sure you can use " " and { } as a
  delimitor.  Thanks go to Dr Reinhold Bader for this fix....  Kent

2006-08-23  sirdude <sirdude>

  * tcl/modulecmd.tcl: "module use"   (without args) was broken, now its fixed
  again.  Kent

  * tcl/modulecmd.tcl: fixed revision variable stuff.  Kent

  * tcl/modulecmd.tcl: Added in cvs revision variables so that module help
  prints out what version of cvs file was checked out.  Kent

2006-08-16  sirdude <sirdude>

  * tcl/modulecmd.tcl: this is a pathetic commit ;)  Modified the comment for
  g_user so that it says the right thing.  Kent

2006-08-15  sirdude <sirdude>

  * tcl/modulecmd.tcl: This commit removes the remaining warnings generated by
  nagelfar redid a couple of calls to interp eval recoded the replaceFromList
  function so it uses lreplace removed the removeFromList function and made it
  call replaceFromList instead...  I also added _LMFILES_ environment variable
  haven't done anything with it yet though.  (intent is to use it in unloading
  a module)  Kent

  * tcl/modulecmd.tcl: removed all of the hardcoded default path seperators
  ":" and replaced with a variable.  Kent

2006-08-14  sirdude <sirdude>

  * tcl/init/.cvsignore: added scripts that get created so that they don't
  show up in cvs update...  Kent

  * tcl/modulecmd.tcl: fixed a few calls to catch and made sure they called it
  in a similar manor... (there are two more left that are slightly different
  but I didn't take the time to figure them out)  one of the fixes was posted
  by Chris Pruett, and I just applied it where it needed it... :)  Kent

  * tcl/modulecmd.tcl: added an else statement that I dropped by accident when
  merging module command and module command help slave functions...  Also
  reran frink so it looks pretty again...  Kent

2006-08-13  sirdude <sirdude>

  * tcl/modulecmd.tcl: more work on seperator specification. (removing
  hardcoded ":"'s  Kent

  * tcl/modulecmd.tcl: combined a couple of duplicate statements in a switch.
  Kent

  * tcl/modulecmd.tcl: Start of allowing a spwcified seperator for commands.
  Still needs a lot of work...  Kent

  * tcl/modulecmd.tcl: made module switch behave like it use to... (Sorry it
  took so long to switch it back)  now it does not recursively unload and
  reload modules... This way seems more flexable and more intunitive to users.
  Kent

2006-08-12  sirdude <sirdude>

  * tcl/modulecmd.tcl: by accident shut off showing default module files....
  Turning it back on.  Kent

  * tcl/modulecmd.tcl: module avail with flag_default_dir was broken This
  fixes it.  Kent

  * tcl/modulecmd.tcl: Null module was causing problems with module avail -l
  There were some odd settings for null which I just changed to "" everything
  seems to work better this way so going to commit it.  Kent

  * tcl/modulecmd.tcl: Updated the help section so its more like the binary
  module command...  Kent

  * tcl/init/bash.in, tcl/init/ksh.in, tcl/init/zsh.in: fix up bash's friends
  so they work properly...  Kent

  * tcl/modulecmd.tcl: updated module-info so that it works with the
  module-info module for the most part.  There is still some work here.  Patch
  submitted by Mark Moraes  Kent

2006-08-11  sirdude <sirdude>

  * tcl/Makefile, tcl/modulecmd.tcl, testsuite/config/unix.exp: updated Make
  test so it "works" again... combined functions for looking at .version and
  modulerc files...  Kent

  * tcl/modulecmd.tcl: This one has been on my todo list for awhile now.
  Reduced redundant code and made the slave for module help and executing a
  module one function.  Kent

  * tcl/modulecmd.tcl: removed the following functions: module-log
  module-verbosity module-user module-trace  they were empty, if anyone ever
  decides to do them they can add them back in. just trying to make this thing
  a little leaner ;)  Kent

  * tcl/modulecmd.tcl: ran frink -e to make things look pretty again ;)  Kent

  * tcl/modulecmd.tcl: I used nagelfar.tcl (http://nagelfar.berlios.de/) a tcl
  syntax checker and cleaned up most warnings from it. found a couple of typos
  as well because of it....  Kent

  * tcl/modulecmd.tcl: another typo.  (was missing a $ for a variable)  Kent

  * tcl/modulecmd.tcl: Removed the code to find tclsh since its in the init
  scripts no reason to duplicate it and probably will speed things up a bit
  keeping it in the init files.  Kent

  * tcl/modulecmd.tcl: On irix with an older version of tclsh I was getting
  errors with reportWarning and reportInternalBug  not being defined when
  there was a malformed module...  made it so they were copied over to the
  slave where needed.  Kent

  * tcl/modulecmd.tcl: missed some prints to stderr and I also fixed some
  typos...  Kent

  * tcl/modulecmd.tcl: made $contact = emailaddress and modified
  reportInternalError so it prints out the contact email address.  Kent

  * tcl/modulecmd.tcl: moved all puts stderr's to one of the report functions.
  This could still use some cleaning up.  (not really sure we need 3 report
  functions) but its at least a little nicer. (Was thinking about changing it
  to echo "$msg" instead of sending it to stderr... that way you could do
  things like module avail | more and it would work...  Need to do some more
  testing on it though :)  Kent

  * tcl/init/csh.in, tcl/init/tcsh.in: removed extra quotes that didn't need
  to be there.  Kent

2006-05-31  sirdude <sirdude>

  * tcl/modulecmd.tcl: * minor typos in error output fixed * support for
  modules which are known to have no dependencies. Presently a  module switch
  foo/4 foo/5  will reload all modules which have been loaded after foo. But
  sometimes this may be a nuisance, especially if module files implement their
  own reloading mechanism. Hence the modules entered as a ":" separated list
  into the environment variable MODULE_NORELOAD will not be reloaded during a
  module switch. The "module reload" command however still reloads the complet
  e module set. This is upward compatible since the original functionality is
  re tained if MODULE_RELOAD is left empty.  patch provided by Dr. Reinhold
  Bader  Kent

  * cmdModule.c, cmdPath.c, init.c, modules_def.h: Rolled in the
  Tcl_GetStringResult() changes from 3.2.0

  * modulefiles/lang/.mklang: Fine-tuned the logic of dealing with $LANG and
  $LANG_STACK. Added some target language verbage.

  * .cvsignore, ChangeLog, Makefile.am, modulefiles/Makefile.am,
  modulefiles/lang/.cvsignore, modulefiles/lang/.mklang, po/.cvsignore,
  po/ChangeLog, po/LINGUAS, po/Makevars, po/POTFILES.in: Added the lang
  modulefiles and upgraded the Makefile.am-s to create a working distribution
  tar ball.

2006-02-05  rkowen <rkowen>

  * Makefile.am: After 'gettextize'.

  * configure.ac: The changes of 'gettextize', note that autopoint is not too
  smart with AC_CONFIG_AUX_DIR ... it appends on any text after macro to the
  directory name.  So do not add 'dnl' for comments or to escape the \n.

2006-02-04  rkowen <rkowen>

  * ChangeLog: Updated.

  * version.c: The current version for the i18n mods is 3.3 alpha

  * main.c: Alert translators to the "common" strings.

  * error.c: Fixed grammar error.

  * utility.c: [ 730293 ] remove-path won't remove paths with a $ in it. Made
  the change and the tests ran fine.  I'm not sure what cleanse_path() is
  supposed to do.

  * init.c: [ 672612 ] Tcl command execution failed and modules use pointed
  out the use of the deprecated Tcl fn Tcl_VarEval(). Replaced this with
  Tcl_Eval() and added some Tcl logic to handle when $auto_path is not set.

  * init/perl.in: Fixed where it needs to reference $ENV{...} [ 705033 ] Bug
  in init/perl

  * init/perl.in: Added 1 at end so perl/init can be used by the perl require.

  * cmdConflict.c: Removed i18n from the debugging statements ... not
  necessary.

  * Makefile.am, utility.c: Rolled in the changes from 3-2-0 patch1

2006-01-31  rkowen <rkowen>

  * ModuleCmd_Avail.c, ModuleCmd_Help.c, ModuleCmd_Init.c, ModuleCmd_List.c,
  ModuleCmd_Update.c, ModuleCmd_Use.c, ModuleCmd_Whatis.c, cmdConflict.c,
  cmdModule.c, cmdUname.c, cmdVersion.c, cmdXResource.c, configure.ac,
  error.c, getopt.c, init.c, locate_module.c, main.c, modules_def.h,
  utility.c: First pass through tagging all the translateable text with
  _(...), etc. for easy extraction by xgettext.  Passes all tests.

2006-01-26  rkowen <rkowen>

  * Makefile.am, configure.ac, main.c, modules_def.h: Setting up autoconf for
  handling i18n & l10n.

  * configure.ac: The AC_AIX check needs to be before any compiler tests.
  Added the AM_GNU_GETTEXT macro for i18n & l10n.

2006-01-23  rkowen <rkowen>

  * Makefile.am, modules.lsm.in: Updated for LSM version 4

2006-01-19  rkowen <rkowen>

  * ChangeLog, Makefile.am, modules.lsm.in: Changed from sunsite to ibiblio
  (same thing though).

  * modules.lsm.in: Can't ftp into the SourceForge.net site.

2006-01-18  rkowen <rkowen>

  * version.c: Ready for the 3.2.0 release

  * MACHINES, NEWS: News about eliminating --with-force-path.

2006-01-17  rkowen <rkowen>

  * ChangeLog, README, cmdModule.c, configure.ac, modules_def.h, utility.c:
  Removed the --with-force-path option ... which basically makes sure that
  PATH and LD_LIBRARY_PATH have some minimum values, given by a couple of
  MODULE_*_SACRED env.vars.  If you need something like this, then you've
  probably written your modulefiles wrong!

  * cmdXResource.c: Eliminated the C++ style commented lines.

  * config/emtcl.m4: Shortened option to --with-tcl-ver and fixed some minor
  problems with it.

  * configure.ac: Fixed what happens when no /bin/csh and the split_size is
  not set.

  * utility.c: Add some casts to eliminate warning messages.

2006-01-12  rkowen <rkowen>

  * .cvsignore, doc/.cvsignore, etc/.cvsignore, init/.cvsignore: More things
  to ignore.

  * ModuleCmd_Init.c, NEWS, version.c: Reworked the "module init*" subcommand
  to handle dot files with multiple "module load" lines.

  * INSTALL: Added the documentation related to --with-tcl-*.

  * config/emtcl.m4, config/tcl.m4, configure.ac: Reintroduced (or added) the
  configure options --with-tcl-{versions|lib|include} to allow the user to
  specify any values which may be missing from the tclConfig.sh script.

  * testsuite/home/.modules, testsuite/home/.modules.save,

  remove command.

  * utility.c: Minor formatting changes.

  * modules_def.h: Minor reformatting.

  * Makefile.am: Added INSTALL.RH7x to the distribution pkg.

2005-12-15  rkowen <rkowen>

  * ChangeLog: Update ChangeLog

  * ChangeLog, INSTALL: Updating the INSTALL doc for 3.2.0

  * version.c: Time for the 3.2.0 release

2005-12-14  sirdude <sirdude>

  * tcl/modulecmd.tcl: Added the system command.  Kent

2005-12-13  sirdude <sirdude>

  * tcl/modulecmd.tcl: Fix by Marcus Wagner.  Makes it so module unload works
  the same way module load does. Specifically for the break command.  Kent

2005-12-12  sirdude <sirdude>

  * tcl/modulecmd.tcl: Fix provided by Mark Moraes.  Prevents modulefilename
  collisions by prepending slaves with __ before commit if you had a module
  file named: module-info and tried to do a module show module-info you would
  get: bad option "mode": must be alias, aliases, eval, expose, hide, hidden,
  issafe, invokehidden, or marktrusted invoked from within "module-info mode
  whatis " Now it works.  Kent

  * tcl/modulecmd.tcl: removed unused variable junk from 3 places in the code.
  (was just setting it to "" in all 3 places)  Kent

2005-12-06  rkowen <rkowen>

  * ChangeLog: Updated.

2005-12-05  rkowen <rkowen>

  tests.

  * ChangeLog, Makefile.am, NEWS, cvs2cl.pl, stripmkf, version.c: Added the
  cvs2cl.pl perl script for generating the ChangeLog semi-automatically.
  Removed stripmkf - an artifact from older releases.

  * ChangeLog, etc/Makefile.am, ext/Makefile.am: Put the add.modules/add.ext &
  mkroot scripts under the --prefix bin directory since those scripts are
  platform independent, and the modules modulefile will point to these
  scripts.

2005-12-02  rkowen <rkowen>

  * ChangeLog, configure.ac, init/Makefile.am, modulefiles/Makefile.am: Put
  the init/ scripts under the --exec-prefix directory, because they point to
  the platform specific modulecmd.

2005-11-30  rkowen <rkowen>

  * ChangeLog, cmdSetenv.c, configure.ac, init/.modulespath.in,
  modulefiles/Makefile.am, modules_def.h, utility.c, version.c: * Eliminated
  any warnings caused by using Tcl 8.4 * Fixed any mixed size differences when
  using ints and pointers. (Only an issue with 64 bit machines.)

  modules_def.h, utility.c, version.c: Added the CONST84 qualifier to

2005-11-27  rkowen <rkowen>

  * config/tcl.m4: It's not an error (exit) if it can't find tclxConfig.sh!

2005-11-26  rkowen <rkowen>

  * Makefile.am: Should read the sf.net file-release-system notes before
  changing the ftp-sourceforge target.

  * Makefile.am, configure.ac, modules.lsm.in: Updated the LSM and the
  creation and handling of distribution tarballs.

  * Makefile.am, modulefiles/Makefile.am: Rolled in the Make versioning
  install fragment from the predeep branch.

  testsuite/modules.50-cmds/075-alias.exp,
  testsuite/modules.50-cmds/078-refresh.exp: Finished the alias/refresh tests
  for sourcing a tmpfile, and also the special case for the Bourne shell where
  funcs and no aliases.

2005-11-22  rkowen <rkowen>

  cmdModule.c, cmdPath.c, cmdSetenv.c, cmdTrace.c, cmdUlvl.c, doc/module.1.in,
  main.c, modules_def.h: * ModuleCmd_Refresh.c: Like "update" but refreshes
  only the non-persistent attributes of the currently loaded modules,
  regardless of the state of the loaded modules (i.e. refresh aliases). (still
  needs some test code)

  * ChangeLog, cmdConflict.c, version.c: * cmdConflict.c: Fixed memory
  allocation bug in cmdPrereq(). When there is more than 1 argument to the
  prereq command, both savedlens and savedlists were indexed past what the
  initial malloc allowed.

2005-11-15  sirdude <sirdude>

  * tcl/modulecmd.tcl: Updated alias function so that it also works on ksh. I
  tested it on a couple of different sh shells and everything seems to work
  this way, and it wasn't working on some of them before.  Kent

2005-07-21  sirdude <sirdude>

  * tcl/modulecmd.tcl: Made it so g_debug is passed to the module files.

2005-05-09  sirdude <sirdude>

  * tcl/modulecmd.tcl: Removed error message that shouldn't be print there. It
  was printing an error complaining it couldn't find a module even though it
  could.

2005-05-05  sirdude <sirdude>

  * tcl/modulecmd.tcl: Added a space between columns in module list command.
  Kent

2005-04-27  sirdude <sirdude>

  * tcl/modulecmd.tcl: Fix so module swap perl perl works the same as module
  swap perl  (before was different if you had a different version than the
  default loaded)  Kent

  * tcl/modulecmd.tcl: Ran modulecmd.tcl through frink since no one complained
  about doing it.  Kent

  * tcl/modulecmd.tcl: added lazy find for module switch  Example: Say you
  have the following modules   perl/5.6 perl/5.8(default) and you have
  perl/5.6 loaded currently. Now you can do module switch perl perl and it
  will unload perl/5.6 and load perl/5.8 before it would error saying the perl
  module is not loaded.  Kent

2005-04-19  sirdude <sirdude>

  * tcl/modulecmd.tcl: I added -l and -t options for module list and module
  avail also fixed resolveModuleVersionOrAlias up a bit so it deals with
  module(default)  Kent

2005-04-15  sirdude <sirdude>

  * tcl/modulecmd.tcl: fix (default) display on modules that are "deep"
  soft/xemacs/21.4   etc....  Kent

  * tcl/modulecmd.tcl: made reload unload all modules then load them all in
  the proper order. Similar to module swap.  Kent

2005-04-14  sirdude <sirdude>

  * tcl/modulecmd.tcl: Modified module switch so it unloaded last module first
  down to the module its swapping out and then reloaded everything in order.
  Before it was unloading them starting at the module to be swapped out to the
  end and then loading them in the same order.  Probably not a big deal but
  code is actually shorter now and is probably more correct.  I also added -a
  and -append as alternatives to --append and --prepend for module use.
  (There were comments saying it would be nice to have that)  Kent

  * tcl/modulecmd.tcl: fixes module whatis problem with (default) before it
  wasn't able to find modules that had a .version file.  Kent

  * tcl/modulecmd.tcl: Added two more globals DEF_COLUMNS and
  MODULES_CURRENT_VERSION and removed hardcoded bits relating to them.  Also
  removed some misc code that was commented out and no longer used.  Kent

2005-04-08  sirdude <sirdude>

  * tcl/modulecmd.tcl: Fix module swap so that it unloads old module and
  everything after it then loads new and everything that was after old.  Kent

  * tcl/modulecmd.tcl: Fix up module init(cmds) I made them behave like the c
  versions example before the initadd added a module to every module load line
  now it just does the first.  I have a ~/.modules directory and before this
  caused the init(cmds) to fail.  Also made it so it only changes one file not
  all . files it goes through.  Kent

2005-04-07  sirdude <sirdude>

  * tcl/modulecmd.tcl: Moved some global variables up to the top of the file.
  Kent

2005-04-06  sirdude <sirdude>

  * tcl/modulecmd.tcl: Modified patch for prereq's I also fixed a small
  problem in the module show  for prereq's  Kent

  * tcl/modulecmd.tcl: Rodney Mach's unalias fix  Kent

2004-11-18  lakata <lakata>

  * tcl/README-EMACS.txt, tcl/init/.cvsignore, tcl/init/lisp.in: submitted by
  tbennett@nvidia.com

  * tcl/init/Makefile, tcl/modulecmd.tcl: patch for Emacs from
  tbennett@nvidia.com

2004-11-05  lakata <lakata>

  * tcl/modulecmd.tcl: added more error checking to init/modulerc. probably
  should change this yet again to standardize the naming convention

  * tcl/modulecmd.tcl: changed hardcoded path to /home/Mark etc to
  $MODULESHOME

2004-10-22  lakata <lakata>

  * tcl/init/README.txt: added instructions on using the new autoinit feature

  * tcl/modulecmd.tcl: added autoinit feature. not documented until we get
  some feedback

2004-10-22  harlan <harlan>

  * locate_module.c: cleanup/refactor

  * configure.ac: cleanup

  * ModuleCmd_Avail.c: USE_COLCOMP -> DEF_COLLATE_BY_NUMBER

  * Makefile.am: Alphabetize...

2004-10-15  lakata <lakata>

  * tcl/modulecmd.tcl: * made compatibility changes with tcl < 8.1.  string
  equal changed to string match and changes to regular expressions.  There is
  now a caveat: module init* commands won't work if there are tabs in your
  startup file around the module commands if tcl < 8.1. * Fixed display so
  that setenv values don't give an error if used later in the module during
  display  * Fixed bug with Perl.  rendersetting output now ends with "1;" for
  perl so that the require command works correctly  * Changed noexistent path
  error to warning in cmdModuleUse. Otherwise, if you gave more than one path,
  some of the other legal paths may not get added.  This is a revert back to
  how modulecmd was originally and probably breaks compatability with the C
  version in this regard

2004-10-13  lakata <lakata>

  * tcl/modulecmd.tcl: * Fixed ModulesHelp so that it doesn't error out when
  not present * Added module-verision,module-alias, module-trace, module-user,
  module-verbosity, and module-log  to module file execution. All but
  module-version and module-alias give a warning that it is not implemented *
  Added module-trace, module-user, module-verbosity, and module-log to
  modulerc execution.  All give warnings that the funcionatlity is not
  implemented * Added #%Module checking on .version and .modulerc files *
  execute-version will now add version defaults to the global defaults array
  like .modulerc files do * .version files are no longer executed if a
  .modulerc is executed in the same directory * module-info symbols command
  implemented (could use more testing) * module-info version command
  implemented (could use more testing) * moduule-info alias command
  implemented * module-version - fixed problem of adding duplicate version
  aliases to global hash * module-alias updated to keep track of aliases by
  module name in global hash * Fix unload-path so that setenv-path followed by
  prepend-path works during unload * fixed bug in is-loaded.  It took a list
  of modules as an argument but would return true if only one of the arguments
  was loaded.  Now all arguments have to be loaded to return true. * Added
  getVersAliasList function.  Returns list of default and version aliases
  given a modulename/version * Added default and version alias information to
  avail and list output * Added a few more "----" to the module list output

  * tcl/modulecmd.tcl: modulecmd.tcl

2004-10-07  lakata <lakata>

  * tcl/modulecmd.tcl: (1) Andrew Barbers changes to fix some bugs. (2) Mark
  Lakatas change to sym links under cygwin. removed check for MODULEPATH,
  since you can use "module use ..." to set it

2004-10-05  lakata <lakata>

  * tcl/modulecmd.tcl: from Andrew Barber: Here is another update.  This one
  has some tricky changes.  Most of it was done to try and get the testsuite
  to pass.  I added a few more features too. The biggest changes were in:
  getPathToModule - now it can resolve aliases found in .modulerc and .version
  files , runModulerc - now this is responsible for finding and executing the
  global .modulerc files (new feature for tcl version)

  * tcl/modulecmd.tcl: patch from Tony Bennett.  need for gentoo system

2004-10-01  lakata <lakata>

  * tcl/modulecmd.tcl: Andrew Barbers changes: * added module-verision and
  module-alias commands, * added automatic of execution .modulerc files found
  in module directories, * added switch processing and -debug switch for debug
  messages

2004-09-30  lakata <lakata>

  * tcl/modulecmd.tcl: (1) added more commands to the internal "module"
  command (2) added all of the init* commands, like initadd (3) changed the
  help message slightly

2004-09-23  sirdude <sirdude>

  * tcl/modulecmd.tcl: David Mores patch so that first module in module list
  is shown again.  Sorry about that I should have caught that before...  Kent

  * tcl/modulecmd.tcl: Mark Moe's patch to prevent infinate loop when you have
  module a loading module b where module b has a .version that points to
  unavailable version of module b  Kent

2004-09-21  sirdude <sirdude>

  * tcl/modulecmd.tcl: David Mores,  patches to the COLUMNS stuff.  Kent

  * tcl/modulecmd.tcl: Mark Moe's patch for skipping 0 length modules in
  module list and adding the printing of: "Currently Loaded Modulesfiles:"
  Kent

2004-09-16  sirdude <sirdude>

  * tcl/modulecmd.tcl: Harlan Stenn's Patch from Phong Nguyen,  It basically
  wraps the openning of a tmpfile in a catch command  I also updated the error
  message after it to use the tmpfile var instead of hardcoding it...   Kent

2004-05-25  sirdude <sirdude>

  * tcl/init/bash.in, tcl/init/csh.in, tcl/init/ksh.in, tcl/init/perl.in,
  tcl/init/python.in, tcl/init/sh.in, tcl/init/tcsh.in, tcl/init/zsh.in: tcl
  version of modules now looks at environment var TCLSH if it exits and uses
  that first.  Suggested by David Astrom.  Kent

  * tcl/modulecmd.tcl: Use  env(COLUMNS) if its defined instead of a hard
  coded number. submitted by David Astrom through Mark Lakata.  Kent

2004-04-21  sirdude <sirdude>

  * tcl/modulecmd.tcl: David Mores patch to prevent tcl version from hanging
  with a .version file that does not set the ModulesVersion correctly.  Kent

2004-01-16  sirdude <sirdude>

  * tcl/Makefile: removed clean and test from the default make.  Kent

  * tcl/Makefile, testsuite/config/unix.exp: Made it so that the testsuite
  works with the tcl version of modules. Current stats for the tcl version
  are: # of expected passes            146 # of unexpected failures        376
  Not too shabby, I'm guessing it will be fairly straight forward to increase
  this by quite a bit.  Kent

2004-01-15  sirdude <sirdude>

  * tcl/init/bash.in, tcl/init/csh.in, tcl/init/ksh.in, tcl/init/perl.in,
  tcl/init/python.in, tcl/init/sh.in, tcl/init/tcsh.in, tcl/init/zsh.in:
  Modified the tcl init files so that they try to find tclsh, this should make
  them quite a bit faster assuming they find it. (This way it locates the
  shell just once instead of for every single command.)  Kent

  * tcl/modulecmd.tcl: Improved module help functionatlity for the tcl version
  of modules. now you can type module help (module)  also commiting the patch
  someone submitted to the board that allows for .version files in directorys
  other than the top level. (for tcl version only)  Kent Mein

2003-10-30  harlan <harlan>

  * tcl/modulecmd.tcl: bash requires a space after the { on function
  definitions.

  * tcl/modulecmd.tcl: Remove the /tmp file early.  Use the "function" keyword
  when creating sh functions; otherwise if the function already exists the
  name gets expanded on some shells.

2003-10-28  lakata <lakata>

  * tcl/modulecmd.tcl: prevent "break" from generating an error message

2003-10-27  lakata <lakata>

  * tcl/modulecmd.tcl: 1) module-info shell and shelltype would generate an
  TCL error when used (FIXED) 2) remove-path had two typos in it (FIXED) 3)
  Added detection of full path in getPathToModule procedure

2003-10-20  lakata <lakata>

  * tcl/modulecmd.tcl: 1) Add support for the other shells that the C version
  includes 2) Add support for prereq command 3) Replace the "/bin/uname" calls
  to use the tcl_platform variable and "info hostname" command  Enclosed are
  my latest modulecmd.tcl updates. I have added most of the features that I
  thought it needed and implemented the slave interpreter to execute
  modulefile in. I have tested it to some degree but not very seriously.
  Richard.M.Born@seagate.com

2003-10-15  lakata <lakata>

  * tcl/modulecmd.tcl: fixed two bugs in the display command

2003-10-07  lakata <lakata>

  * tcl/modulecmd.tcl: cleaned up the mode and modulename settings that used
  to be access via the upvar. also changed the calling convention for
  getPathToModule, which now does not throw an exception for minor warnings

  * tcl/modulecmd.tcl: fixed a bug where the result of the catch is either an
  error or the last command

2003-10-06  lakata <lakata>

  * tcl/modulecmd.tcl: fixed a bug in the popMode command and made it backward
  compatible with tcl 8.0

  * tcl/modulecmd.tcl: 1. pulled all references to puts stderr to
  report/reportWarnings/reportInternalBug. 2. changed the way the g_mode
  variable is handled. Instead of relying on the call stack, it now uses an
  explicit stack, which should solve any problems with using other namespaces
  3. removed a bunch of debugging statements. 4. fixed the way errors are
  handled, giving more meaningful responses. 5. if an error is caught in load,
  the env/alias settings are NOT updated and restored to a previous state. for
  instance, in a conflict this is important.

  * tcl/modulecmd.tcl: fixed bug in listModules that was failing on cygwin

2003-10-03  lakata <lakata>

  * tcl/modulecmd.tcl: Proxy check in for Richard.M.Born@seagate.com. He
  wrote:  1) It didn't handle modulefiles in the main directory for commands
  like module avail 2) It didn't define the ModulesCurrentModulefile variable
  3) It didn't ignore certain temp files (*~, #*#) 4) It didn't look for the
  Modulefile MagicCookie to filter out non-modulefiles  I have updated
  modulecmd.tcl to address these issues. I have removed lsHack and replaced it
  with listModules procedure. I am not familiar with the glob issue that you
  noted for Cygwin so you may want to run a few test cases to see if the new
  function still works for you. I also updated the module paths command to
  what I think you were intending.

2003-08-08  harlan <harlan>

  * tcl/modulecmd.tcl: Changes to lsHack for cmdModulePath and friends.

2003-08-07  harlan <harlan>

  * tcl/modulecmd.tcl: Typo

  * tcl/modulecmd.tcl: Add $Revision$ to the version

  * tcl/modulecmd.tcl: Initial support for "module path".

2003-08-02  harlan <harlan>

  * tcl/modulecmd.tcl: /bin/sh has no shell functions.  Avoid an extra call to
  getPathToModule

2003-08-01  harlan <harlan>

  * tcl/modulecmd.tcl: whitespace cleanup, lose cruft.

2003-07-30  lakata <lakata>

  * tcl/README.txt, tcl/modulecmd.tcl: version 0.98: fixed a bug in the
  error_count (missing closing brace). also implemented check to abort the
  tempfile sourcing if the tempfile is empty. this is to be more blackboxish,
  avoiding relying on the shell to do a clean up. one of our users is not
  using the module command correctly, and it is created a whole bunch of empty
  /tmp/modulescript files in the /tmp dir.

2003-07-15  harlan <harlan>

  * tcl/modulecmd.tcl: Begin to handle errors.

2003-07-10  harlan <harlan>

  * ChangeLog, tcl/modulecmd.tcl: * tcl/modulecmd.tcl: If g_force is set,
  ignore *_modshare.  When we produce a shell function, preface the definition
  with "function" in case it's already defined.  Default g_force to 1 now.

2003-06-26  harlan <harlan>

  * tcl/modulecmd.tcl: ModuleTcl: 0.97 Aliases: add/load, rm/inload,
  nodename/node We need to eval more "cmdModule{Unl,L}oad $arg" lines to:
  Implement --append (and --prepend) for cmdModuleUse Use -dictionary lsorts
  to provide an easy substitute for colcomp(). Added SCCS and RCS to the
  ignoreDir list. Moved ignoreDir processing to lsHack to fix a problem. Make
  sure an empty modulefile direcoty doesn't cause an error.

2003-06-02  harlan <harlan>

  * tcl/init/README.txt: Reformat some long lines.

2003-05-30  lakata <lakata>

  * tcl/init/README.txt, tcl/init/bash.in, tcl/init/csh.in, tcl/init/ksh.in,
  tcl/init/modulerc, tcl/init/perl.in, tcl/init/sh.in, tcl/init/tcsh.in,
  tcl/init/zsh.in: changed the way MODULEPATH is set up. since this is another
  environment variable like all the others, it is now set using the module
  command itself. pretty sneaky, huh?

  * tcl/modulecmd.tcl: 1. added the "source" command (experimental) 2. added
  sanity checking to verify that something external did not muck with path and
  path_modshare variables. 3. fixed a bug if you use tcsh and your paths get
  longer than 1024 characters. Previously, it was truncating the path, but
  this can get you into trouble if important things like /usr/bin or
  /usr/local/bin are truncated. The real solution is to STOP USING TCSH... use
  zsh instead.

2003-03-28  lakata <lakata>

  * tcl/README.txt, tcl/modulecmd.tcl: changes for cygwin. files should not
  have cr/lf (DOS) endings.

  * tcl/init/Makefile, tcl/init/README.txt, tcl/init/bash, tcl/init/bash.in,
  tcl/init/{csh => csh.in}, tcl/init/ksh, tcl/init/ksh.in, tcl/init/{perl =>
  perl.in}, tcl/init/{python => python.in}, tcl/init/sh, tcl/init/sh.in,
  tcl/init/{tcsh => tcsh.in}, tcl/init/zsh, tcl/init/zsh.in: made init files
  more general

2003-01-22  lakata <lakata>

  * tcl/init/perl: error checking if something goes wrong in perl

  * tcl/modulecmd.tcl: fixed bugs with corrupted env vars, improved the
  reliability of _modshare variables

2002-11-29  lakata <lakata>

  * tcl/modulecmd.tcl: changed help message

  * tcl/README.txt, tcl/init/bash, tcl/init/csh, tcl/init/ksh, tcl/init/perl,

  TCL_INCLUDES.  * lib/tests/Makefile.am (EXTRA_PROGRAMS): Renamed from
  noinst_PROGRAMS.  Lose the .x suffixes.  * lib/Makefile.am
  (ACLOCAL_AMFLAGS): Look in ../config/ .

  lib/uvec.man, locate_module.c, main.c, modules_def.h, utility.c: 2002-09-16
  R.K. Owen   <rk@owen.sj.ca.us> * colcomp.c: removed * utility.c: added
  colcomp.c contents * Makefile.am: removed colcomp.c * main.c: Added
  DEF_COLLATE_BY_NUMBER output for --version * configure.ac: changed
  USE_COLCOMP to DEF_COLLATE_BY_NUMBER, and added memdebug * locate_module.c:
  changed USE_COLCOMP and GetModuleName for deep dirs. * modules_def.h: check
  for HAVE_CONFIG_H, and added memdebug * ModuleCmd_List.c: Simplified using
  uvec objects

  * lib/Makefile, lib/Makefile.am, lib/Makefile.in, lib/memdebug.c,
  lib/memdebug.h, lib/memdebug.man, lib/tests/Makefile.in: Added the memdebug
  headerfile and sources.

  * cmdVersion.c, locate_module.c, modules_def.h: Fixed up GetDefault to
  handle .modulerc and .version files, where the latter will read the env.var.
  defined in .version and do a module-version so that the modlist data can be
  updated. These mods handle deep dirs on "module load" ... now need to fix up
  the rest! There's also now an amazing amount of cruft to weed out.

2002-08-14  lakata <lakata>

  * README: updated docs to reflect new configure (TCL paths)

  * locate_module.c, modules_def.h: removed compiler warnings about const
  char*

  -L/usr/X11R6/lib

  * cmdInfo.c, cmdVersion.c: removed compiler warnings

  testsuite/modules.70-maint/020-update.exp: * Made the .modulesbeginenv
  facility optional (default is not to have it) * default for cache is now
  "no" * Added version_test() to testsuite to make some of the tests
  conditional on the values generated by --version. - the configure options
  help is formatted with AC_HELP_STRING

2002-06-14  rkowen <rkowen>

  * .cvsignore, ChangeLog, Makefile.am, Makefile.in, config.h.in,
  config/compile, configure, configure.ac, doc/Makefile.in, etc/.cvsignore,

  ext/Makefile.in, init/Makefile.am, init/Makefile.in, init/filter,
  init/zsh.in, modulefiles/Makefile.am, modulefiles/Makefile.in,
  testsuite/etc/.cvsignore: * Reworked every configure-based file - uses
  automake to generate most of the Makefile.in - renamed configure.in to
  configure.ac per autoconf - Versioning is optional now with a configure
  option - reworked the init scripts for versioning or not - eliminated
  acconfig.h and put templates in configure.ac - make install now honors the
  DESTDIR variable for package builds - honors bindir for modulecmd location
  (but the init scripts are only correct if no versioning) * Collected the
  usage info and now it can be displayed with the --help or -H option (same as
  help) * --version now gives most of the optional configure parameters for
  easy debugging of problems * Fixed bootstrap to just source the appropriate
  init script

  * Makefile.am, Makefile.in, acconfig.h, config.h.in, configure,
  configure.ac, etc/Makefile.am, etc/Makefile.in, etc/add.modules.in,

  init/bash.in, init/csh.in, init/ksh.in, init/perl.in, init/python.in,
  init/sh.in, init/zsh.in: Removed the acconfig.h file since it's essentially
  in the configure.ac now. Reworked all the init,skel,add.* files to handle
  versioning or no. Added Makefile.am to ./etc/ and ./ext/ for cleaner
  installs.

2002-06-13  rkowen <rkowen>

  * Makefile.am, Makefile.in, ModuleCmd_Help.c, acconfig.h, config.h.in,
  doc/module.1.in, main.c, modules_def.h,
  testsuite/modules.00-init/015-version.exp: The version info displays some of
  the configuration options. Moved the usage info into module_usage() that can
  be displayed with the --help or -H switch.

  * Makefile.am, Makefile.in, ModuleCmd_Whatis.c, acconfig.h, config.h.in,
  configure, configure.ac, main.c: Renamed INSTPATH to PREFIX and is no longer
  passed as a compiler -D argument, but is now entered directly into the
  config.h header.

2002-06-12  rkowen <rkowen>

  * Makefile.am, Makefile.in, ModuleCmd_Bootstrap.c, init.c, main.c,
  modules_def.h, utility.c: Converted the configure scripts over to
  automake,autoconf generation. Modified "module bootstrap" to source the init
  files. Put the shell properties and moved set_derelict and renamed it
  set_shell_properties into init.c . Created a matrix of shell properties {
  name, derelict, init, cmd separator }.

  * testsuite/etc/apropos.cache, testsuite/modules.50-cmds/095-uname.exp:
  Fixed test syntax - it didn't like "dangling" ('s and )'s in regexp string.
  Just escaped them. Removed apropos.cache - it gets regenerated with each
  test.

  * ModuleCmd_Switch.c, testsuite/modules.50-cmds/170-swap.exp: Fixed up
  "module switch" one argument form (use stringer alloc) and added more tests
  (one for each of the major shells).

2002-06-11  rkowen <rkowen>

  * acconfig.h, config.h.in, configure, configure.ac: Added MODULES_INIT_DIR
  to the configure files.

  * Makefile.am, Makefile.in, ModuleCmd_Bootstrap.c, acconfig.h, acinclude.m4,
  aclocal.m4, config.h.in, configure, configure.ac: Upgraded the

  init/zsh.in: Re-introduced the init files with versioning.

  * config/depcomp, config/install-sh, config/install.sh, config/missing,
  config/mkinstalldirs: Upgraded install scripts to automake/1.6 autoconf/2.53
  standards.

2002-06-06  rkowen <rkowen>

  * configure.in => configure.ac: configure.ac is actually the continuation of
  configure.in. do "cvs log configure.in" for a history.
  ---------------------------- revision 1.11 (of configure.in) date:
  2002/04/29 21:16:48;  author: rkowen;  state: Exp;  lines: +145 -116 *
  Upgraded configure.in to autoconf 2.52.  * Changed  the configure to search
  for libTcl.sh to acquire all it's necessary Tcl env.vars from it.

2002-05-06  rkowen <rkowen>

  special chars.

2002-04-30  rkowen <rkowen>

  * install.sh, version.c: Moved install.sh to config/ and updated the version
  to 3.2.0a .

  config/tcl.m4, configure, configure.in, error.c, init.c, locate_module.c,
  main.c, modules_def.h, utility.c: * Upgraded configure.in to autoconf 2.52.
  * Changed  the configure to search for libTcl.sh to acquire all it's
  necessary Tcl env.vars from it.  * created a utility function stringer() to
  handle most of the strcpy/strcat operations and to automatically allocate
  string memory.  * Mostly changed the memory malloc/free to use
  stringer/null_free.  * rewrote some of the code logic to have a single point
  of exit with unwinding of memory allocations.

2002-04-29  lakata <lakata>

  * ModuleCmd_Bootstrap.c: fixed bug with binary_name without an absolute path

  * ModuleCmd_Help.c: fixed help for swap|switch, to reflect optional first
  modulefile1

  * ModuleCmd_Bootstrap.c, config.h.in, configure, configure.in: added PREFIX
  to config.h and propagated to bootstrap code as MODULESHOME

  * doc/module.1.in: updated docs regarding "switch" and MODULESHOME

  * ChangeLog: "module switch foo/1.3" change log

  * ModuleCmd_Bootstrap.c, ModuleCmd_Switch.c, error.c, modules_def.h: added
  support for 1-arg form of "swap/switch" command

  * ModuleCmd_List.c: sanity check added in case _LMFILES_ and LOADEDMODULES
  env vars get corrupted externally

  * testsuite/modules.50-cmds/170-swap.exp: added test for one-argument form
  of swap/switch command

2002-04-24  lakata <lakata>

  * ChangeLog: more stuff

  * init/tcsh.in: tcsh is now generated from csh, not tcsh.in

  * init/Makefile.in: tcsh script is copy of csh script

  * init/csh.in: fixed csh init script to deal with funny shell chars like *
  and {}

  * utility.c: (1) removed unset -f for zsh unaliasing  (2) removed single
  quotes for quoting env vars. This breaks if the env var itself has single
  quotes. The more robust method is to individually escape all the dangerous
  characters.  Old method: setenv foo 'bar bar'  New method: setenv foo bar\
  bar  (3) removed tmpnam and tempname stuff, replacing with safer
  tmpfile_mod()

  * config.h.in, configure, configure.in: added TMP_DIR define

  * cmdXResource.c: suppress warning if DISPLAY is not set

  * cmdModule.c: fixed help message

  * aclocal.m4: fixed problem with finding tcl lib using glob

  centering source on TESTSUITEDIR, rather than rely on "pwd" or relative
  paths, which prohibit running the testsuite from a different dir (b) removed
  autoconf/configure processing of testsuite

  * INSTALL: Added more information about configuring TCL and a few other
  prerequisites.

  * configure: reran autoconf. see configure.in log

  * probetcl: probetcl functionality is now in aclocal.m4

  * configure.in: (a) reordered configuration, so that critical things are
  done first (aids in debugging to get the hardstuff done first). (b) removed
  some of the testsuite configuration (c) added -with-tcl-library
  configuration (d) changed the help messages

  * config.h.in: removed redundant lines

  * cmdXResource.c: (a) fixed regular expression for XRDB parsing (b) fixed

  dir eq ".", but was done using a char comparison, not string comparison.
  Caused severe problems if dir was "..", since only first character was used.

2002-03-08  lakata <lakata>

  A 'break' in a modulefile will cause the modulefile to not be added to
  $LOADEDMODULES, but will be considered a successful execution to not affect
  other modulefiles being loaded concurrently (Patch due to Scott Gaskins). *
  Tests and docs added for the above.

  environment for all users through the system shell files.  Is specific to
  Linux/RedHat 7.x, but is of general applicability. * Added further tests for
  modulefile "module use dir_path" (found an unload bug that will be fixed
  before release) * Environment variable contents are now quoted to preserve
  any embedded environment variables. (Needed for versioning) * Added over 50
  tests specific to module versioning, and testing xgetenv. * Fixed the
  unsetenv on unload function, the feature added in 3.0.6-rko was supposed to
  set the env.var. to the optional third argument. This was to allow old
  env.var. values to be recovered by unraveling a stack set in an other
  env.var.  Added tests for this feature. This is used by the version
  modulefile. * Fixed and updated the version modulefile to allow stacked
  versions to be removed the stack. * Removed an annoying spurious stderr
  newline.

2001-06-22  rkowen <rkowen>

  * ModuleCmd_Help.c: Spurious fprintf(stderr,...) was adding anomalous blank
  lines to the tests.

2001-06-10  rkowen <rkowen>

  * Makefile.in, testsuite/modulefiles.other/README: Fixed the way a
  distribution tar ball is made.  It makes only one CVS connection instead of

  * Makefile.in: Removed other references to "-rko" in version numbers.

  * Makefile.in: Fixed tag rule to use the cvs module "module" instead of
  "module-3.1rko"

  * ChangeLog: Updated for 3.1.1 release.

  * configure.in: Added init/python

  * Makefile.in: Updated version number of 3.0 to 3.1.

  * version.c: Bumped up version number for new release

2001-01-16  rminsk <rminsk>

  * init/python.in: Removing blank lines

  * init/Makefile.in, init/python.in: Fixing typeo's

  * init/Makefile.in, init/python.in: Adding python init files.

  * utility.c: Fixing bug the the _LMFILES_ environment variable.  As the
  _LMFILES_ shrink in size the extra _LMFILES%03d_ were not being unset.  Made
  sure extra _LMFILES%03d_ are removed each time _LMFILES_ is set.  Added
  initial support for scheme (scm, guile).  Made output of ksh (bash, zsh)
  aliases recognize the escape charater ("\"). This was important to be able
  to escape "$".  Anytime an alias had a "$" in it a function was always
  output.  Fixed a bug in search of the LOADEDMODULES environment variable.
  Would not correctly find a module if only a partial module name was given.
  For example "maya/3.0" would be found but "maya" would not.  In the process
  of fixing this bug a possible memory corruption was also fixed.

  * init/csh.in: Removed variable histchar.  It was not being used.  Modified
  to store the current prompt and unset prompt while modules is running.  A
  bug in csh will cause and eval of an eval (eval `eval ...`) to output a
  prompt.  This cause the first eval to try to execute the prompt.

  * init.c: Fixing bug the the _LMFILES_ environment variable.  If the user is
  using csh and _LMFILES_ is large than LMSPLIT_SIZE it gets split into
  _LMFILES.%03d_. For modules to work correctly the split _LMFILES.%03d_ must
  be joined to make _LMFILES_.
