Release notes
*************
This file describes changes in recent versions of Modules. It
primarily documents those changes that are of interest to users and
admins.
Modules 4.5.2 (2020-07-30)
==========================
* Init: "list" and "source" sub-commands do not take available
modules as argument in fish completion script.
* Init: fix option list for "search" sub-command in bash completion
script.
* Fix double error counter increase when modulefile evaluation
breaks.
* Install: adapt "configure" script to pass to the "configure"
script of Modules compatibility version only a subset of the options
it supports (most commonly used options).
* Install: raise an error when an unknown option is passed to
"configure" script rather silently ignore it. (fix issue #348)
* Install: enable the definition of installation directory options
of "configure" script with the "--option value" syntax in addition
to the "--option=value" syntax. (fix issue #348)
* Doc: alphabetically sort sub-commands of "module-info" modulefile
Tcl command in modulefile document.
* Script: clean previously built environment-modules RPMs in
**mrel**.
* Clearly separate quarantine variable definition from tclsh binary
on "modulecmd.tcl" evaluated command call in "_module_raw" function
for *sh*, *bash*, *ksh* and *zsh* shells. (fix issue #350)
* Doc: clarify in documentation index that Environment Modules
should not be confused with language-specific modules. (contribution
from Rob Hurt)
* Adapt conflict detection tests to ensure a module loaded by its
full pathname will not detect itself as a conflict when declaring a
reflexive conflict. (fix issue #352)
* Adapt the **mrel** and **mpub** commands to produce new Modules
release from a *vZ.Y.x* git branch rather than from the repository
main branch.
Modules 4.5.1 (2020-06-01)
==========================
* Install: consistently output Makefile warning messages on stderr.
* Script: add the "mrel" script, that automates build of the Modules
release files and performs tests over these distribution files to
guaranty their correctness.
* Script: add the "mpub" script, that automates Modules new release
publishing over git repositories and websites.
* Install: remove project-specific tools from git repository export
thus from release distribution files.
* Disable pager when "clear" sub-command is called from "ml"
shortcut command. (fix issue #338)
* In case a modulefile evaluation fails, environment context prior
this failed evaluation is restored. Fix environment variable
restoration mechanism to keep the link that monitors and updates
environment variable array "env" in every Tcl sub-interpreters. (fix
issue #340)
* Ensure environment variable change at the Tcl interpreter level is
propagated to every sub-interpreters used to evaluate modulefiles or
modulercs. (fix issue #342)
* Use absolute path to load Modules Tcl extension library. (fix
issue #344 with contribution from Roy Storey)
* Fix formatting of error stack trace not to look for internal
commands to withdraw if start-up stack pattern cannot be matched.
Modules 4.5.0 (2020-04-07)
==========================
* Doc: fix typos and grammar mistakes on module, modulefile and
Differences between versions 3.2 and 4 documents. (contribution from
Colin Marquardt)
* Doc: update cookbook recipes to highlight code of the Tcl scripts
included. (contribution from Colin Marquardt)
* Doc: improve markup of module, modulefile and Differences between
versions 3.2 and 4 documents to enable references to module sub-
commands, command line switches, environment variables and
modulefile Tcl commands. (contribution from Colin Marquardt)
* Doc: alphabetically sort module sub-commands, command-line
switches, environment variables and modulefile Tcl commands in
module and modulefile documents.
* Introduce the "ml" command, a handy frontend to the "module"
command. "ml" reduces the number of characters to type to trigger
"module". With no argument "ml" is equivalent to "module list", "ml
mod" corresponds to "module load mod" and "ml -mod" means "module
unload mod". Multiple modules to either load or unload can be
combined on a single command. "ml" accepts all command-line switches
and sub-commands accepted by "module" command. "ml" command is
defined by default. Its definition can be controlled at
"./configure" time with "--enable-ml" option or later on with "ml"
configuration option (which defines "MODULES_ML" environment
variable when set).
* Fix module sub-command abbreviation match to ensure passed
abbreviated form fully match sub-command, not only its minimal
abbreviated form. As an example, "lod" or "loda" do not match
anymore the "load" sub-command, "lo" or "loa" still do.
* Add the "-j"/"--json" command line switches to the "avail",
"list", "savelist", "whatis" and "search" module sub-commands to
render their output in JSON format. (fix issue #303)
* Script: remove need to build project management-specific tools
("mtreview", "mb", "mlprof" and "playdemo") prior using them.
* Script: gather all distributed and maintained scripts in a
"script" directory at the root of the project repository tree.
* Install: provide Windows-specific batch files when "./configure"
option "--enable-windows-support" is set. module command wrapper
"module.cmd" is installed in "bindir" and initialization script
"cmd.cmd" in "initdir". Those batch files are relocatable and expect
"modulecmd.tcl" in "..\libexec" directory. (fix issue #272 with
contribution from Jacques Raphanel)
* Install: add ml command wrapper "ml.cmd" and install it in
"bindir" when "./configure" option "--enable-windows-support" is
set.
* Install: introduce envml command wrapper "envml.cmd" for Windows
"cmd" shell and install it in "bindir" when "./configure" option "--
enable-windows-support" is set. (contribution from Jacques Raphanel)
* Doc: improve documentation portal index.
* Install: add "dist-win" target to Makefile in order to build a
distribution zipball containing the required files to run Modules on
a Windows platform. "INSTALL.bat" and "UNINSTALL.bat" Windows batch
files are introduced and shipped in the zipball to automate
installation and basic configuration of Modules on the Windows
platform.
* Doc: update Installing Modules on Windows document to describe how
to install Modules with newly provided Windows-specific distribution
zipball.
* Install: enable build of Modules from "git archive" tarball or
zipball exports (like download source archives automatically
provided on GitHub project)
* Install: ship reStructuredText and MarkDown source documents at
the root of Modules distribution tarball rather their built txt
counterpart.
* Script: fix "createmodule.sh" script to correctly analyses
environment when shell functions are found defined in it.
* Script: inhibit output generated by scripts evaluated by
"createmodule.sh" and "createmodule.py" to ensure these outputs will
not get in the way when analyzing the environment changes. (fix
issue #309)
* Correctly handle symbolic version target including a whitespace in
their name.
* Testsuite: output test error details whatever the testsuite run
verbose mode.
* Install: adapt configure script and Makefile to detect "python"
command location and set it as shebang for "createmodule.py" and
"gitlog2changelog.py". If "python" command is not found, "python3"
then "python2" are searched.
* Install: enable to pass a specific Python interpreter command name
or location at configure step with "--with-python" option. Specified
command name or location should be found on build system only if
building from git repository.
* Install: build "createmodule.py" script and install it in
"bindir".
* Install: update RPM spec file to explicitly define Python
interpreter location.
* Script: fix "createmodule.py" script for Python3 (fix issue #315
with contribution from Armin Wehrfritz)
* Lift Perl variable strictness when defining "_mlstatus" variable
in case "modulecmd.tcl" output is directly evaluated without use of
the "module" sub-routine in Perl script. (with contribution from
Andrey Maslennikov)
* Script: fix path de-duplication in "createmodule.sh". (fix issue
#316)
* Doc: add *Handling Compiler and other Package Dependencies*
cookbook recipe, which discusses various strategies for creating
modulefiles for packages with multiple builds depending on
previously loaded compiler, MPI libraries, etc. (contribution from
Tom Payerle)
* Init: test availability of "compopt" Bash builtin prior using it
in Bash completion script to avoid error with versions of this shell
older than 4.0. (fix issue #318)
* Install: adapt configure step to detect if "sed" option "-E" is
supported and fallback to "-r" otherwise in shell completion
scripts. (fix issue #317)
* Add support for the "NO_COLOR" environment variable (https://no-
color.org/) which when set (regardless of its value) prevents the
addition of ANSI color. When set, "NO_COLOR" prevails over
"CLICOLOR" and "CLICOLOR_FORCE" environment variables.
"MODULES_COLOR" overrides these three variables. (fix issue #310)
* Script: when analyzing environment variable changes in
"createmodule.sh" applied by shell script passed as argument,
produce a "setenv" modulefile statement for any variable found set
prior script evaluation and for which value is completely changed
after script evaluation. (fix issue #320)
* When an error message is composed of multiple lines, render it in
the same way whether it is part of a block message or not: lines
after the first one are prepended with a 2-space padding. As a
result error messages appear clearly separated from each other.
* Append to the error message the error stack trace when a general
unknown error occurs in "modulecmd.tcl" and provide a link to
encourage users to report such error to the GitHub project.
* Add to the error message the error stack trace for errors
occurring during site-specific configuration evaluation. Error stack
is expunged from the "modulecmd.tcl" internals to only report
information relevant to site-specific configuration file.
* When an error occurs during the evaluation of a modulefile or a
modulerc, report associated error stack trace expunged from
"modulecmd.tcl" internal references to only output useful
information for users.
* GitHub: add issue templates to guide people submitting a bug
report or a feature request.
* Doc: provide a link toward issues that have been fixed between
versions 3.2 and 4.0 in Differences between versions 3.2 and 4
document.
* Script: introduce "envml.cmd" script for Windows platform
providing similar behavior than "envml" Bash script. (contribution
from Jacques Raphanel)
* Init: add Bash shell completion for the "ml" command.
(contribution from Adrien Cotte)
* Fix Fish shell stderr redirection for newer Fish versions. (fix
issue #325)
* Correctly handle modulefiles and modulepaths containing a space
character in their name whether they are used from the command-line,
in collections, within modulefiles or from loaded environment
definitions.
* Doc: add *Default and latest version specifiers* design note.
* An "avail" search over a symbolic version targeting a directory
now correctly returns the special modules (alias and virtual module)
lying in this directory. (fix issue #327)
* "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. (fix issue #328)
* alias and virtual module whose name mention a directory that does
not exists are correctly handled. (fix issue #168)
* Hide special modules (aliases, symbolic versions and virtual
modules) whose version name starts with a dot character (".") from
"avail", "whatis" and "paths" searches if their query does not fully
match special module name. (fix issue #329)
* Filter-out from the output of the "aliases" sub-command all hidden
aliases, symbolic versions or hidden modules targeted by a non-
hidden symbolic version. (fix issue #330)
* Enable resolution of default module in module sub-directory when
this default symbol targets a hidden directory (whose name starts
with a dot character). (fix issue #331)
* Doc: clarify hidden module location in modulefile man page.
* Install: define "LD_PRELOAD" as quarantine var along with
"LD_LIBRARY_PATH" in RPM specfile.
* When "implicit_default" and "advanced_version_spec" configuration
are enabled, automatically define a "default" and "latest" symbolic
version for each module name (at each module depth for deep modules)
if those version names does not already exist. (fix issue #210)
* Once a module is loaded, the automatically defined symbols
associated to it are recorded in loaded environment in the
"MODULES_LMALTNAME" environment variable. They are distinguished
from the other alternative names applying to the module by a "as|"
prefix, which qualifies their *auto symbol* type.
* When an advanced version specifier list contains symbolic version
references, fix resolving to honor default version if part of the
specified list. (fix issue #334)
Modules 4.4.1 (2020-01-03)
==========================
* Fix error and warning messages relative to dependency management
to enclose dependency specification in single quotes to clearly
distinguish specification from each other.
* Skip output of module loading message if module is already loaded.
* Doc: add demonstration material played at SC19 to promote the new
features of Modules.
* Contrib: add "playdemo" script to play recorded demonstration
cast.
* Doc: add a web anchor to each modulefile Tcl command, module sub-
command and module environment variable documentation.
* Install: update RPM spec file to enable build on "el8".
* Doc: fix RST syntax for bullet lists in design docs. (fix issue
#306)
* In case "module avail" query does not match a directory but only
its contained elements (for instance "module av mod/7" matches
"mod/7.1" and "mod/7.2" but not "mod/"), fix query processing to
correctly return latest or default element in case "--latest" or "--
default" flags are set.
* In case a "module avail" query performed in a no-indepth mode with
" --latest" or "--default" flags either enabled or disabled, fix
query processing to return directory elements if they are part of
result.
* When a "module avail" query performed in no-indepth mode targets a
virtual module, fix result to filter-out the directory holding the
virtual module from result.
* Fix "module avail --default" queries when modulefile default
version does not match query: select latest version from modulefiles
matching query unless "implicit_default" configuration is disabled
in which case no default version is returned.
* Improve highlighting of module "avail" and "whatis" search result
by coloring module names matching search query expressed with the
advanced version specifiers. "name@1,3" or "name@1:3" queries now
highlight "name/1" and "name/3" strings found in search result.
* Contrib: add the "mlprof" script which wraps "modulecmd.tcl" to
collect profiling information on its execution.
* Contrib: adapt "mb" script to profile "modulecmd.tcl" run tests
rather bench them when "profile" argument is passed to the script.
* Improve overall performances of module names and versions
comparison by introducing optimized procedures and caching in memory
module search results.
Modules 4.4.0 (2019-11-17)
==========================
* Doc: add *Return file basename on module-info name for full path
modulefile* recipe to cookbook. (fix issue #297)
* Rework internal handling of configuration options to gather all
option definitions in a global array and use the same initialization
and retrieval procedure, named "getConf", for all these options.
* Add the "setConf", "unsetConf" and "lappendConf" procedures to
provide unified ways to set the value of configuration option. These
procedures should be used in site configuration files to override
configuration option value instead of directly setting corresponding
option variable as it was done in previous Modules releases.
* Add the ability to match module specification in a case
insensitive manner. Default case sensitiveness behavior is set at
"./configure" time with the "--with-icase" option. It could be
superseded with the "MODULES_ICASE" environment variable, that could
be set with "config" module sub-command through the "icase" option.
Command-line switch "--icase" ("-i") enables to supersede defined
case sensitiveness configuration. (fix issue #212 with contribution
from Eric Deveaud)
* Introduce the extended default mechanism, to help selecting a
module when only the first numbers in its version are specified.
Starting portion of the version, part separated from the rest of the
version string by a "." character, will get matched to the
appropriate complete version name. In case 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" option is disabled and no explicit default
is found among matches, an error is returned. This mechanism is
enabled through a new configuration option named "extended_default"
(which defines "MODULES_EXTENDED_DEFAULT" environment variable when
set). It may be enabled by default in "modulecmd.tcl" script with
option " --enable-extended-default" passed to the "./configure"
script.
* Introduce the advanced module version specifiers mechanism to
specify finer constraints on module version. This new feature
enables to filter the module selection to a given version list or
range by specifying after the module name a version constraint
prefixed by the "@" character. It leverages the version specifier
syntax of the Spack package manager. A single version can be
specified with the "@version" syntax, a list of versions with
"@version1,version2,...", a greater than or equal to range with
"@version1:" syntax, a less than or equal to range with "@:version2"
and an in between or equal to range with "@version1:version2"
syntax. In case "implicit_default" option is disabled and no
explicit default is found among version specifier matches, an error
is returned. This mechanism is enabled through a new configuration
option named "advanced_version_spec" (which defines
"MODULES_ADVANCED_VERSION_SPEC" environment variable when set). It
may be enabled by default in "modulecmd.tcl" script with option "--
enable-advanced-version-spec" passed to the "./configure" script.
* Conflict defined with a generic module name or an advanced version
specifier may match multiple loaded modules (generally in case
multiple loaded modules share same root name). Loaded environment
analysis has been fixed to bind conflict to all loaded modules
matching it. As a result the *Dependent Reload* mechanism is not
triggered when one loaded module matching conflict is removed if
another loaded module still match the conflict.
* Doc: add *Module selection contexts*, *Insensitive case*,
*Extended default* and *Advanced module version specifiers* design
notes.
* Make "MODULESHOME" environment variable controllable through the
"config" sub-command with "home" configuration option. A "--with-
moduleshome" argument is also added to the ./configure script to set
specific default value for this option at installation time. (fix
issue #292)
Modules 4.3.1 (2019-09-21)
==========================
* Contrib: add "mb" script to bench Modules versions.
* Correct "modulecmd.tcl" script startup to correctly report error
in case Tcl extension library fails to load. (fix issue #284)
* Install: fix typo on "CFLAGS" definition in "lib/Makefile". (fix
issue #287 with contribution from Felix Neumärker)
* Remove useless code in Modules Tcl extension library
* Make URLs in README correctly rendered in HTML. (contribution from
Per Persson)
* Doc: clarify modulefile evaluation modes in modulefile.4 man page.
(fix issue #289)
* When looking at the closest match among loaded modules when
switching module with just a single module argument specified, load
the information on the currently set environment to get the
alternative names of loaded modules prior to look at closest module
match. (fix issue #290)
* Doc: describe the way to determine the site-specific configuration
script location in cookbook recipes implying the installation of
such a file. (fix issue #266)
* Doc: add *Log module command* recipe to cookbook. (fix issue #283)
* Doc: add *Expose procedures and variables to modulefiles* recipe
to cookbook.
* Doc: add *Make defined modulepaths persist over sudo* recipe to
cookbook.
* Doc: add *Ensure user fully qualify the modules they use* recipe
to cookbook.
* Introduce the "wa_277" configuration option to workaround an issue
with Tcsh history mechanism. Default "module" alias definition for
Tcsh hits an issue with shell history mechanism: erroneous history
entries are recorded each time the "module" command is called. When
"wa_277" 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. (fix issue #277)
* Doc: add *Tips for Code Reuse in Modulefiles* recipe to cookbook.
(contribution from Tom Payerle)
* Fix the "whatis" and "paths" sub-command results for module
symbolic versions targeting a directory when "implicit_default"
configuration option is disabled. No error is returned and same
result is now obtained whether the symbolic name or its target is
used as argument for those two sub-commands. (fix issue #294)
* Fix the "whatis" and "paths" sub-command results for module
aliases targeting a directory when "implicit_default" configuration
option is disabled. No error is returned and same result is now
obtained whether the alias name or its target is used as argument
for those two sub-commands. (fix issue #295)
* Rework all the ternary operator expressions in "modulecmd.tcl"
that may result in a *nan* value (whatever the case used to write
this string) as the "expr" Tcl command raises an error when it
returns such a value, which breaks Modules as soon as a modulefile,
an alias or a symbolic version is named *nan*. (fix issue #296)
Modules 4.3.0 (2019-07-26)
==========================
* Introduce Vim addon files to highlight the modulefile syntax.
Installation of these files, which is enabled by default, is
controlled by the "--enable-vim-addons" and "--vimdatadir" configure
options. (contribution from Felix Neumärker)
* 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.
* 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.
* Introduce Modules Tcl extension library (written in C) to extend
Tcl language in order to provide more optimized I/O commands to read
a file or a directory content than native Tcl commands do.
* Install: add "--libdir", "--enable-libtclenvmodules", "--with-tcl"
and "--with-tclinclude" options to configure script to control
libtclenvmodules build and installation.
* When an error is caught during modulecmd.tcl first initialization
steps, ensure the error report facility is initialized to render
error message.
* When looking for modulefiles in enabled modulepaths, take
".modulerc" file found at the root of a modulepath directory into
account. Which means these rc files are now evaluated like global rc
files and can be used to define module aliases targeting modulefiles
stored in the underlying file tree.
* Correctly get available default (-d) and latest (-L) version
whether search pattern is passed with an ending forward slash
character or not or if it contains a "*" wildcard character.
* Append a forward slash character to any directory result of an
avail command to better distinguish these directories from regular
files.
* Introduce the ability to control whether "avail" command search
results should recursively include or not modulefiles from
directories matching search query by use of the "--indepth" and "--
no-indepth" command-line switches or the environment variable
"MODULES_AVAIL_INDEPTH". Default behavior is set at the
"./configure" time with the "--enable-avail-indepth" and "--disable-
avail-indepth" switches. (fix issue #150)
* Update "bash", "fish" and "zsh" completion scripts to propose
available modulefiles in the no in depth mode.
* Add the ability to graphically enhance some part of the produced
output to improve readability by the use of the "--color" command-
line switch or the "MODULES_COLOR" environment variable. Both accept
the following values: "never", "auto" and "always". When color mode
is set to "auto", output is colored if stderr is attached to a
terminal. Default color mode could be controlled at configure time
with the "--enable-color" and the "--disable-color" option, which
respectively correspond to the "auto" and "never" color mode.
* Control the color to apply to each element with the
"MODULES_COLORS" environment variable or the "--with-dark-
background-colors" and "-- with-light-background-colors" configure
options. These variable and options take as value a colon-separated
list in the same fashion "LS_COLORS" does. In this list, each
element that should be highlighted is associated to a Select Graphic
Rendition (SGR) code.
* Inform Modules of the terminal background color with the
"MODULES_TERM_BACKGROUND" environment variable or the "--with-
terminal-background" configure option, which helps to determine if
either the dark or light background colors should be used to color
output in case no specific color set is defined with the
"MODULES_COLORS".
* Color prefix tag of debug, error, warning, module error and info
messages.
* Highlight the modulefile or collection name when reporting
messages for a an action made over this modulefile or collection.
* Color the modulepaths reported on a "use" command.
* Highlight title of separator lines or column name of table header.
* Color modulepaths, directories, aliases and symbols reported by
the "avail", "aliases", "list", "whatis" and "search" commands.
* When color mode is enabled and module aliases are colored, do not
associate them a "@" tag as the color already distinguish them from
regular modulefile.
* When color mode is enabled and a Select Graphic Rendition (SGR)
code is set for the "default" modulefile symbol, apply this SGR code
to the modulefile name instead of associating it the "default"
symbol tag.
* Highlight matched module search query string among "avail",
"whatis" and "search" command results.
* Highlight the modulefile and collection full path name on
"display", "help", "test" and "saveshow" command reports.
* Color modulefile Tcl commands set in a modulefile on a "display"
command report.
* Color module commands set in a collection on a "saveshow" command
report.
* Re-introduce "clear" sub-command. (fix issue #203)
* Leverage "--force" command-line switch on "clear" sub-command to
skip confirmation dialog. (fix issue #268)
* Init: improve readability of variable definition operations by
writing one definition operation per line rather having multiple
commands on a single line like "VAR=val; export VAR". (fix issue
#225)
* Add the ability to define a site-specific configuration file with
an environment variable: "MODULES_SITECONFIG". When set, the script
file pointed by the variable is sourced (if readable) after the
site-specific configuration file initially defined in
"modulecmd.tcl". (contribution from Ben Bowers, fix issue #234)
* Doc: add description in the module.1 man page of "MODULERCFILE" in
the environment section and "siteconfig.tcl" in the files section.
* Install: provide at installation time a bare site-specific
configuration script in designated "etcdir" if no pre-existing
"siteconfig.tcl" file is found at designated location.
* Introduce the "config" sub-command to get and set "modulecmd.tcl"
options and to report its current state.
* Contrib: update "createmodule.py" script to support execution from
the *cmd* shell. (contribution from Jacques Raphanel, fix issue
#270)
* Add the ability to configure when unloading a module and multiple
loaded modules match request if firstly loaded module should be
chosen or lastly loaded module. Configure option "--with-unload-
match-order" defines this setting which can be superseded with the
"MODULES_UNLOAD_MATCH_ORDER" environment variable. This variable can
be set with the option "unload_match_order" on the "config" sub-
command. By default, lastly loaded module is selected. It is
recommended to keep this behavior when the modulefiles used express
dependencies between each other.
* Add the ability to configure whether an implicit default version
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 through the "implicit_default"
option.
* Install: add to the configure script the "--with-locked-configs"
option to ignore environment variable superseding of Modules
configurations defined in "modulecmd.tcl" script. Lockable
configuration option are "extra_siteconfig" and "implicit_default".
Currently locked options are reported through the "locked_configs"
option on the "config" sub-command.
* Introduce the ability to control the module search match. Search
query string should match module name start or any part of module
fully qualified name. Default search match behavior is set at
"./configure" time with the "--with-search-match" option. It could
be superseded with the "MODULES_SEARCH_MATCH" environment variable,
that could be set with "config" module sub-command through the
"search_match" option. Command-line switches "--starts-with" ("-S")
and "--contains" ("-C") for "avail" module sub-command enable to
supersede defined search match configuration.
* Introduce the ability not to set the shell startup file that
ensure "module" command is defined once shell has been initialized.
Setting shell startup file currently means defining "ENV" and
"BASH_ENV" environment variables to the Modules bourne shell
initialization script. "./configure" options "--enable-set-shell-
startup" and "-- disable-set-shell-startup" define if shell startup
should be set or not by default. It could be superseded with the
"MODULES_SET_SHELL_STARTUP" environment variable, that could be set
with "config" module sub-command through the "set_shell_startup"
option.
* Cookbook: add the *test-modulefiles* recipe. (fix issue #182 with
contribution from Colin Marquardt)
* Fix location of global RC file to "@etcdir@/rc" instead of
"@prefix@/etc/rc" to cope with "@etcdir@" specific setup ("@etcdir@"
defaults to "@prefix@/etc").
* Take into account Modules initialization configurations found in
"etc" directory if they exist rather in "init" directory. If
"initrc" configuration file is found in "etcdir" then it is
preferred over "modulerc" file in "initdir". Following the same
trend, "modulespath" configuration file is found in "etcdir" then it
is preferred over ".modulespath" file in "initdir".
* Introduce the ability to install the Modules initialization
configuration files in the "etcdir" rather than in the "initdir". A
new configure option is introduced for this task: "--with-initconf-
in". Accepted values for this option are: "etcdir" or "initdir"
(default).
* Add the "--enable-modulespath" configure option, which is an alias
for the "--enable-dotmodulespath" option as ".modulespath"
configuration file is named "modulespath" when installed in
"etcdic".
* Install: update RPM spec file to disable "set_shell_startup"
option by default, set "/etc/environment-modules" as configuration
directory and store Modules initialization configuration files in
it.
* Report an error when a module load or unload evaluation aborts due
to the use of the "break" or "exit" modulefile commands. This error
notification clarifies that module evaluation failed. (fix issue
#267)
* Remove the message block display output for the "reload", "purge"
and "restore" sub-commands to preserve this output style for
modulefile evaluation modes (load, unload and switch) and thus
clarify understanding.
* When unloading a module that contains a "module load" or "module
switch" modulefile command, inhibit the unload performed of the
useless requirement when auto_handling mode is disabled if currently
performing a "purge", "reload" or "restore" sub-command. As the
unload sequence is determined and managed from these top commands.
* Add ability to control module command message verbosity with
configuration option. Introduced verbosity levels from the least to
the most verbose are "silent", "concise", "normal", "verbose" and
"debug". This option could be set at "./configure" time with "--
with-verbosity" option. It could be superseded with the
"MODULES_VERBOSITY" environment variable, that could be set with
"config" module sub-command through the "verbosity" option. Silent,
verbose and debug verbosity modes can be set at the command-line
level respectively with "--silent"/"-s", "--verbose"/"-v" and "--
debug"/"-D" command-line switches. (fix issue #204)
* When verbosity level is "normal" or higher, reports every module
loads or unloads performed to "restore" a collection or "source" a
scriptfile, even if there is no specific message to output for these
module evaluations. Clarifies what module evaluations have been
triggered by these sub-commands.
* Also honor the "CLICOLOR" and "CLICOLOR_FORCE" environment
variables to define color mode. (fix issue #279)
Modules 4.2.5 (2019-07-08)
==========================
* Correctly escape "?" character in shell alias. (fix issue #275)
* When resolving the enabled list of modulepaths, ensure resolved
path entries are unique. (fix issue #274)
* Right trim '#' characters from the fetched modulefile magic cookie
string to ensure a correct compatibility version comparison. Useful
when modulefile first line is equal to "#%Module4.2##############".
* Fix argument parsing for the "append-path", "prepend-path" and
"remove-path" modulefile commands to consider every arguments found
after the variable name as variable values and not command option
even if argument starts with "-" character. (fix issue #278)
* Fix automatic loading of modulefiles when multiple module names
are set on a single "module load" modulefile command. When
auto_handling mode was disabled, the load of not loaded modules was
not achieved as soon as some modules on this list were already
loaded. (fix issue #281)
Modules 4.2.4 (2019-04-26)
==========================
* 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. (fix issue #244, #245, #246, #247 and #248)
* Doc: preserve quotes and dashes when making HTML docs. (fix issue
#250 with contribution from Riccardo Coccioli)
* Fix hanging "list" sub-command when terminal width is equal to the
single column text width to be printed. (contribution from Jesper
Dahlberg)
* During an additional evaluation triggered by an automated module
handling mechanism, ensure warning and error messages are reported
under the message block of the main evaluation. (fix issue #252)
* During the unload of a module when the automated module handling
mode is disabled, report a warning message for each unload of a
useless requirement that fails as done when the automated module
handling mode is enabled. (fix issue #253)
* When multiple modules are listed on a "prereq" command, drop the
output of those modules that fails to load (by the *Requirement
Load* automated mechanism) to only keep the output of the module
whose load succeed. (fix issue #254)
* Fix "switch" sub-command when the switched-off module cannot be
unloaded when other loaded modules depend on it. Whole switch
process is failed and no load of the switched-on module is
attempted. (fix issue #251)
* When switching modules, report failure of switched-off module
unload or switched-on module load under the message block of the
switch action. A failed switched-off module unload is reported as an
error, as it aborts the switch evaluation, whereas a failed
switched-on module load is reported as a warning. (fix issue #255)
* When a module requirement is seen missing but the load of this
module was attempted, report a more specific error or warning
message to let user understand that the load of the requirement was
attempted but failed. (fix issue #257)
* When loading a module, report any missing requirement on the
message reporting block corresponding to this module load. This
warning or error message comes in addition to the eventual
*Requirement Load* message reported under the message block of the
main evaluation. (fix issue #258)
* When unloading a module which has some dependent module still
loaded, produce a more specific error or warning message if an
evaluation of these dependent modules has been realized or if the
unload of the required module is forced. (fix issue #259)
* When a conflicting module is seen loaded but the unload of this
module was attempted, report a *Conflict Unload* error or warning
message toward the main evaluation message block. (fix issue #261)
* When loading a module, report any loaded conflict on the message
reporting block corresponding to this module load. This warning or
error message comes in addition to the eventual *Conflict Unload*
message reported under the message block of the main evaluation.
(fix issue #261)
* Correctly report loading state of conflicting module. (fix issue
#262)
* Adapt warning, error and info messages relative to the *Dependent
Reload* mechanism to distinguish the unload phase from the load
(reload) phase of this mechanism. In the automated module handling
summary report, unloaded modules via this mechanism are reported in
the *Unloading dependent* list and modules reloaded afterward are
reported against the *Reloading dependent* list. (fix issue #263)
* When the automated module handling mode is disabled, do not
attempt to load a requirement expressed in a modulefile with a
"module load" command, if this requirement is already loaded or
loading.
* Skip load or unload evaluation of a module whose respectively load
or unload was already attempted but failed. If this second
evaluation attempt occurs within the same main evaluation frame.
(fix issue #264)
* When reloading modules through the *Dependent Reload* automated
mechanism, prevent modules to automatically load of other modules
with the "module load" modulefile command, as it is done for the
"prereq" command. (fix issue #265)
* Raise an error when an invalid option is set on "append-path",
"prepend-path" or "remove-path" modulefile command. (fix issue #249)
* Zsh initializes by default the "MANPATH" environment variable to
an empty value when it starts. To preserve "manpath" system
configuration even after addition to this variable by modulefiles,
set "MANPATH" variable to ":" if found empty. (improve fix for issue
#224)
* Doc: provide a short installation guideline in README file. (fix
issue #230)
Modules 4.2.3 (2019-03-23)
==========================
* Add all the module dependency-related internal information to
those saved prior a modulefile evaluation in order to correctly
restore internal state in case modulefile evaluation fails.
* Init: in shell initialization scripts, initialize "MANPATH" if not
set with a value that preserves "manpath" system configuration even
after addition of paths to this variable by modulefiles. (fix
issue#224)
* Enable to define an entire path entry to the "MODULEPATH" variable
which corresponds to a variable reference only. (fix issue#223)
* Cookbook: add the *modulefiles-in-git* recipe. (contribution from
Scott Johnson)
* When "module switch" commands are found in modulefiles, track
switched-off modulefile as a conflict and switched-to modulefile as
a requirement to apply same behaviors than for "module load" and
"module unload" commands in modulefiles. If "module switch" has only
one argument, do not define a conflict toward switched-off
modulefile. *CAUTION: it is not recommended to use `module switch`
command in modulefiles*. (fix issue#229)
* When unloading a module, revert "module switch" commands found in
modulefile: switched-on module is converted to a "module unload",
like for "module load" command. Nothing is done for switched-off
module, like for "module unload" command. (fix issue#226)
* For default element in a modulefile directory which is a module
alias that points to a modulefile, when this modulefile is loaded,
it receives as alternative names the eventual module aliases set on
the distant directory holding the alias pointing to it. (fix
issue#231)
* When unloading a module that contains "module load" or "module
switch" commands in its modulefile, select for unload the
automatically loaded requirement module which has been loaded prior
its dependent. (fix issue#232)
* Doc: describe Emacs settings useful for adhering to coding
conventions in CONTRIBUTING guide. (fix issue #233 with contribution
from Ben Bowers)
* When looking for a loaded or loading dependency requirement,
select among the eventual multiple candidates the closest match to
the dependent module.
* During the unload of a module, if the unload of one of its
dependent (by the *Dependent Unload* mechanism) fails, abort the
whole unload process. Exception made if the force mode is enabled.
In this case failing module stays loaded and the *Dependent Unload*
mechanism continues with next module to unload.
* During the unload of a module, if the unload of one of its useless
requirements (by the *Useless Requirement Unload* mechanism) fails,
keep the requirements of this failing module loaded. Such error is
reported as a warning and it does not stop the whole unload process.
(fix issue#240)
* During the load or the unload of a module, if the unload of one of
its dependent (by the *Dependent Reload* mechanism) fails, abort the
whole unload or load process. Exception made if the force mode is
enabled. In this case failing module stays loaded and *Dependent
Reload* mechanism continues with next module to unload. This failing
module is removed from the *Dependent Reload* list, so it will not
take part of the load phrase of the mechanism. (fix issue#239)
* During the load or the unload of a module, if the load of one of
its dependent (by the *Dependent Reload* mechanism) fails, abort the
whole unload or load process. Exception made if the force mode is
enabled. In this case failing module stays loaded and *Dependent
Reload* mechanism continues with next module to load. When the
mechanism is applied during a "switch" command, force mode is
enabled by default on the load phase. (fix issue#241)
* When reloading all loaded modules with the "reload" sub-command,
if one reloading module fails to unload or load, abort the whole
reload process to preserve environment sanity. (fix issue#237)
* During the unload of a module when the automated module handling
mode is disabled and this module declares its requirements with the
"module load" modulefile command. If the unload of one of its
useless requirements (by the *Useless Requirement Unload* mechanism)
fails, whole unload process is not aborted and continue with next
module to unload. (fix issue#238)
* Contrib: add "mtreview" utility script that analyzes test suite
log file to compare actual and expected output of failed test. "mt"
does not output the full test suite logs anymore but only the
information produced by "mtreview" on failed tests.
* Install: exclude Continuous Integration configurations from dist
tarballs.
Modules 4.2.2 (2019-02-17)
==========================
* Correct the *Dependent Unload* mechanism when it triggers the
unload of 2 modules making together a requirement from another
module. This module is now also added to the dependent modules to
unload.
* Doc: add a cookbook section in the documentation and port there
the 3 pre-existing recipes: *inhibit-report-info*, *top-priority-
values* and *unload-firstly-loaded*.
* Doc: add a CONTRIBUTING guide.
* Doc: fix a typo on the Python initialization example in module man
page.
* Doc: add a FAQ entry to describe the use of module from Makefile.
(with contribution from Robert McLay)
* Trim any white-space, newline or ";" characters at the beginning
or end of the function body passed to set-function modulefile
command.
* Init: add recognition of the "--auto", "--no-auto" and "--force"
command-line switches in fish shell completion script.
* Init: add recognition of the "--auto", "--no-auto", "--force", "--
paginate" and "--no-pager" command-line switches in zsh shell
completion script.
* When the load of a modulefile is asked but a conflict is
registered against this modulefile by an already loaded module, the
load evaluation is now performed and the conflict is checked after
this evaluation. If the conflict is still there, this evaluation
(and the evaluation of its requirements) is rolled back. (fix
issue#216)
* Init: fix "_module_not_yet_loaded" alias in tcsh completion script
to handle situation when "noclobber" variable is set. Also ensure
actual "rm" command is called and not an alias. (fix issue#219)
* Fix warning message when the load of a modulefile is forced over a
reflexive conflict (message was reported twice).
* When looking at the dependency of a loaded module, only consider
requirement loaded before dependent module (holding a prior position
in the loaded module list) as valid. Those loaded after dependent
module are considered as an unmet dependency thus they are not
taking part in the *Dependent Unload*, the *Useless Requirement
Unload* and the *Dependent Reload* mechanisms.
Modules 4.2.1 (2018-11-11)
==========================
* Cookbook: add the *inhibit-report-info* recipe.
* Cookbook: port *unload-firstly-loaded* and *top-priority-values*
recipes to v4.2.
* Init: fix listing of loaded modules for *fish* and *tcsh* shell
completions.
* Init: fix saved collection listing when no collection found for
*bash*, *zsh*, *tcsh* and *fish* shell completions.
* Adapt "system" modulefile Tcl command to execute the command
passed as argument through shell, like it is performed on
compatibility version. (fix issue#205)
* Correctly filter modulefile search memory cache entries when using
a full search result to search later on a specific modulefile.
* Prefix debug messages by information on the current modulefile or
modulerc interpreter if any.
* Init: fix listing of loaded modules on unload and switch sub-
commands for *bash* shell completion.
* Refrain "module unload" modulefile command from unloading a module
required by another loading module.
* Enable "is-loaded" modulefile Tcl command in modulerc
interpretation context, like done on compatibility version. (fix
issue#207)
* Check a required module is not already loading before attempting
to load it. Helps to handle cyclic dependencies.
* Compute loaded modules requirement dependency relations without
cycle and consider the module closing the cycle in a constraint
violation state to avoid reloading loops on the *Dependent Reload*
mechanism.
* Safely unset dependency reference when computing dependency
relations as some dependencies expressed may target same module.
* Ensure a loaded module matching multiple entries of a same *or*
"prereq" will just be considered as one module matching this
requirement.
* Init: quote prompt in *csh* and *tcsh* script with ":q" rather
double quotes to accommodate prompts with embedded newlines. (fix
issue#209 with contribution from Satya Mishra)
* Init: skip shell environment alteration if "autoinit" command
fails. (fix issue#208)
* Reword path-like variable element counter reference handling to
simply ignore the counter values not coherent with the content of
related path-like variable. (fix issue#206)
Modules 4.2.0 (2018-10-18)
==========================
* Add "chdir" and "puts" environment settings to the per-modulefile
evaluation saved context. So previous values of these settings are
restored in case of evaluation failure.
* Fix save and restore of "x-resource" environment settings on the
per-modulefile evaluation context.
* Use the correct warning procedure to report the full reference
counter inconsistency message (so this message is fully inhibited
during global "whatis" evaluations).
* Make "append-path", "prepend-path", "remove-path" and "unsetenv"
commands alter "env" Tcl global array during "display", "help",
"test" or "whatis" evaluation modes. Thus an invalid argument passed
to these commands will now raise error on these modes. (see
Environment variable change through modulefile evaluation context
section in MIGRATING document)
* On "whatis" mode, "append-path", "prepend-path", "remove-path",
"setenv" and "unsetenv" commands initialize variables if undefined
but do not set them to their accurate value for performance concern.
* Clear value instead of unsetting it during an unload mode
evaluation of "setenv" or "*-path" commands to avoid breaking later
reference to the variable in modulefile.
* Make "getenv" command returns value on "help", "test" or "whatis"
evaluation modes. (fix issue#188)
* Add an argument to the "getenv" command to return the value of
this argument if the queried variable is undefined.
* Use a different modulefile interpreter for each evaluation mode.
* Adapt the procedure called for each modulefile command depending
on the evaluation mode to adapt behavior of these commands to the
module command currently running.
* Report calling name and arguments for modulefile commands on
"display" mode. For the commands evaluated during this mode, trigger
this report at the end of the evaluation.
* Inhibit "chdir", "conflict", "module", "module-log", "module-
trace", "module-user", "module-verbosity", "prereq", "set-alias",
"system", "unset-alias", "x-resource" commands on "help", "test" and
"whatis" evaluation modes.
* Ignore "chdir", "module", "module-trace", "module-verbosity",
"module-user" and "module-log" commands found during modulerc
evaluation.
* Correctly restore an empty string value on sub-interpreter global
variables when sanitizing this interpreter between two
modulefile/modulerc evaluations.
* Cache in memory results of a modulefile search to reuse it in case
of rerun instead of re-walking the filesystem.
* Evaluate global rc files once module sub-command is known and
registered, so it can be queried during their evaluation.
* Rename "_moduleraw" shell function in "_module_raw" to use a
common "_module_" prefix for all module-related internal shell
functions.
* Install: add "--enable-append-binpath" and "--enable-append-
binpath" configure options to append rather prepend the bin or man
directory when adding them to the relative environment variable.
* Doc: clarify documentation for module usage on scripting language
like Perl or Python to mention that arguments to the "module"
function should be passed as list and not as a single string.
* When 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.
* Register the conflicts defined by loaded modules in the
environment (variable "MODULES_LMCONFLICT") and ensure they keep
satisfied. (see Modulefile conflict constraints consistency section
in MIGRATING document)
* Register the prereqs defined by loaded modules in the environment
(variable "MODULES_LMPREREQ") and ensure they keep satisfied. (see
Modulefile prereq constraints consistency section in MIGRATING
document)
* Introduce the automated module handling mode, which consists in
additional actions triggered when loading or unloading a modulefile
to satisfy the dependency constraints it declares. Those actions are
when loading a modulefile: the *Requirement Load* and the *Dependent
Reload*. When unloading a modulefile, *Dependent Unload*, *Useless
Requirement Unload* and *Dependent Reload* actions are triggered.
(see Automated module handling mode section in MIGRATING document)
* Track the loaded modules that have been automatically loaded (with
environment variable "MODULES_LMNOTUASKED") to distinguish them from
modules that have been explicitly asked by user. This information
helps to determine what module becomes a useless requirement once
all its dependent modules are unloaded.
* Track in saved collections the loaded modules that have been
automatically loaded by add of a "--notuasked" argument to "module
load" collection lines. So this information is restored in loaded
environment when collection is restored. This "--notuasked" argument
is ignored outside of a collection restore context.
* Consider modules loaded from a "module source" file as explicitly
asked by user.
* Install: add "--enable-auto-handling" configure option to enable
or disable the automatic modulefile handling mechanism.
* Process list of loaded modules or modules to load one by one
during the "restore", "purge" and "reload" sub-commands whatever the
auto handling mode is.
* Add the ability to control whether the auto_handling mode should
be enabled or disabled with an environment variable called
"MODULES_AUTO_HANDLING" or from the command-line with "--auto" and "
--no-auto" switches. These command-line switches are ignored when
called from modulefile.
* Init: add pager-related command-line options in shell completion
scripts.
* Doc: describe "MODULES_LMCONFLICT", "MODULES_LMPREREQ" and
"MODULES_LMNOTUASKED" in module.1 man page.
* Add "-f" and "--force" command-line switches to by-pass dependency
consistency during "load", "unload" or "switch" sub-commands. (see
By-passing module defined constraints section in MIGRATING document)
* Disallow collection "save" or loaded modules "reload" if some
loaded modules have some of their dependency constraints
unsatisfied.
* The *Dependent Reload* action of a "load", "unload" and "switch"
sub-commands excludes modules that have unsatisfied constraints and
includes modules whose constraints are satisfied again (when sub-
command process solves a conflict for instance).
* Doc: describe "--force", "--auto" and "--no-auto" command-line
switches and "MODULES_AUTO_HANDLING" variable in module.1 man page.
* Ignore directories ".SYNC" (DesignSync) and ".sos" (SOS) when
walking through modulepath directory content. (contribution from
Colin Marquardt)
* Install: look for "make" rather "gmake" on MSYS2.
* Fix "exec()" usage in Python module function definition to
retrieve the correct return status on Python3.
* Cookbook: add the *top-priority-values* and *unload-firstly-
loaded* recipes.
* Install: add "gcc" to the build requirements in RPM specfile.
* Silent any prereq violation warning message when processing
*Dependent Reload* mechanism or "purge" sub-command.
* Doc: mention "createmodule.sh" and "createmodule.py" scripts in
FAQ. (fix issue#189)
* Register all alternative names of loaded modules in environment
with "MODULES_LMALTNAME" variable. These names correspond to the
symbolic versions and aliases resolving to the loaded modules. Helps
to consistenly solve "conflict" or "prereq" constraints set over
these alternative names. (fix issue#143 / see Consistency of module
load/unload commands in modulefile section in MIGRATING document)
* Doc: describe "MODULES_LMALTNAME" in module.1 man page.
* Install: add "--with-bin-search-path" configure option to get in
control of the path list used to search the tools required to build
and configure Modules. (fix issue#164)
* Install: add "--enable-silent-shell-debug-support" configure
option to add the ability to control whether or not code to support
silent shell debug should be added to the module function and sh-
kind initialization scripts. (fix issue#166)
* Install: add "--enable-quarantine-support" configure option to add
the ability to control whether or not code to support quarantine
mechanism should be added to the module function and initialization
scripts. (fix issue#167)
* Check version set in modulefile magic cookie. If modulefile sets a
version number greater than "modulecmd.tcl" script version, this
modulefile is not evaluated like when no magic cookie is set at all.
(fix issue#171 / see Express Modules compatibility of modulefile
with versioned magic cookie section in MIGRATING document)
* Fix uninitialized variable in procedure producing list of element
output. (fix issue#195)
* Ensure the consistency of "module load" modulefile command once
the modulefile defining it has been loaded by assimilating this
command to a "prereq" command. Thus the defined constraint is
recorded in the "MODULES_LMPREREQ" environment variable. Same
approach is used for "module unload" modulefile command which is
assimilated to a "conflict" command. Thus the defined constraint is
recorded in the "MODULES_LMCONFLICT" environment variable. (see
Modulefile alias and symbolic modulefile name consistency section in
MIGRATING document)
* Only look at loaded modules when unloading so unloading an
nonexistent modulefile does not produce an error anymore. (fix
issue#199)
* Report error raised from modulefile evaluation as "ERROR" rather
"WARNING", like when a conflict constraint is hit. Moreover this
kind of evaluation error is now silenced on global evaluation like
when proceding "avail" or "search" sub-commands.
* Record messages to report them by block on when processing a
"load" or an "unload" modulefile evaluation to improve readability
on these evaluating modes that may cascade additional actions. (see
Improved module message report section in MIGRATING document)
* Foreground "load", "unload", "switch" and "restore" actions (ie.
asked on the command-line) now report a summary of the additional
load and unload evaluations that were eventually triggered in the
process.
* Support "del" and "remove" aliases for "unload" sub-command like
on compatibility version. (fix issue#200 with contribution from
Wenzler)
* Correctly transmit the arguments along with the command to execute
on "system" modulefile command. (fix issue#201)
* Contrib: add "mt" utility script which helps to run just specific
part of the test suite.
* Introduce "set-function" and "unset-function" modulefile commands
to define shell function on sh-kind and fish shells. (fix issue#193
with contribution from Ben Bowers)
Modules 4.1.4 (2018-08-20)
==========================
* Doc: fix typo on "getenv" command description in modulefile(4) man
page and clarify this command should be preferred over "::env"
variable to query environment variable value in modulefile.
* Init: fix "bash" and "zsh" completion scripts to enable Extended
Regular Expression (ERE) on "sed" command with "-E" argument (rather
"-r") for compatibility with OS X's and BSDs' sed. (fix issue#178)
* Handle default version sets on an hidden modulefile (were not
found previously). (fix issue#177)
* Init: fix "ksh" initialization script for ksh88 compatibility.
(fix issue#159)
* Install: use "sed" command rather "grep" and "cut" in "configure"
and "Makefile" scripts. (fix issue#175 with contribution from
Michael Sternberg)
* Fix typo, tab indentation and pipe opening mode on
"createmodule.py" utility script. (contribution from Jan Synacek)
* Check "ModulesVersion" value set from ".version" rc file to ensure
this value refers to a version name in current directory. Report
error if a nested value is detected and ignore this value. (fix
issue#176)
Modules 4.1.3 (2018-06-18)
==========================
* Make "setenv" command alter "env" Tcl global array during "help",
"test" or "whatis" evaluation modes. (fix issue#160)
* Doc: describe MANPATH variable special treatment on compatibility
version in diff_v3_v4 document.
* Initialize and export _moduleraw SH shell function if "stderr" is
attached to a terminal. Was previously checking "stdout". (fix
issue#169)
* For "csh" shells, quote code generated by modulecmd.tcl to pass it
to the "eval" shell command.
* Escape special characters when producing code to define shell
aliases (fix issue#165)
* Correct modulefile lookup when a modulefile directory is
overwritten by a module alias definition but it contains an empty
sub-directory. (fix issue#170)
* Doc: describe "getenv" command in modulefile(4) man page.
* Improve SH shell detection in profile.sh initialization script to
use shell variable on "bash" or "zsh" to determine current shell
name. (fix issue#173)
Modules 4.1.2 (2018-03-31)
==========================
* Add an example global rc file in "contrib/etc" directory that
ensures "MODULEPATH" is always defined.
* Check "HOME" environment variable is defined on "savelist" and
"is- saved" commands or raise error if not.
* Fix saving of deep module default version in collection when
version pinning is disabled: if "foo/bar/version" is default version
for "foo", collection will retain just "foo" (was retaining
"foo/bar").
* Enable to save and restore collections containing full path
modulefiles eventually with no modulepath defined.
* Run "puts" command not related to "stderr" or "stdout" channels in
calling modulefile context to correctly get access to the targeted
file channel. (fix issue#157)
* Quote "autoinit" result for eval interpretation on SH-kind shells
to avoid parameter expansion to randomly occur on generated code
depending on file or directory names of current working directory.
(fix RH bug#1549664)
* Ignore empty elements found in "MODULEPATH", "LOADEDMODULES" or
"_LMFILES_" to ensure all elements in these variables are non-empty
strings.
* Raise error if loaded environment is in an inconsistent state when
calling commands requiring correlation of information from the
"LOADEDMODULES" and the "_LMFILES_" environment variables. Error
raised on "load", "unload", "switch", "reload", "purge", "list",
"save" and "restore" commands. May affect "info-loaded" or "is-
loaded" commands if module passed as argument to these command is
specified as a full path modulefile.
* Fix "list" command to process loaded modules information before
performing any content output.
* Install: adapt "configure" script and Makefiles to support
installation on Cygwin system.
* Detect terminal width on Windows "cmd" terminal with "mode"
command.
* Improve Windows "cmd" shell support: error code returned, echoing
text, shell alias creation and removal, working directory change.
* Raise error when an empty module name is passed to module sub-
commands like "load", "display" or "unload".
* Raise error when an empty collection name is passed to module sub-
commands like "save", "saveshow" or "restore".
* Raise error when an empty path is passed to module "unuse" sub-
command, like already done on "use" sub-command.
* Clear argument list if an empty module command name is passed.
* Fix "module" function definition for all shells in "autoinit"
command to correctly handle empty-string parameters or parameters
containing white-spaces, quotes, escape characters.
* Fix "module" function definition for Python to accept being called
with no argument.
* Fix parameter expansion on "module" function for all SH-kind
shells when quarantine mode is activated.
* Escape "\" character when producing R shell code.
Modules 4.1.1 (2018-02-17)
==========================
* Make separator lines, used on "display" command result for
instance, fit small screen width.
* Install: give ability to build and install Modules from git
repository without documentation if "sphinx-build" cannot be found.
* Install: adapt "configure" script and Makefiles to support
installation on FreeBSD, Solaris and OS X systems. (fix issue#147)
* Rework code generated by "autoinit" for sh-kind shells to avoid
use of local variables as those are defined differently through the
sh variants. (also fix issue#147)
* Init: use a default value on undefined variables in sh-kind
scripts to avoid unbound variables in bash "-eu" mode. (fix
issue#151)
* Correctly detect terminal column number on Solaris.
* Init: fix csh init script to get compatibility with pure csh shell
* Sanitize content of "MODULEPATH" before using it at run-time, to
make potential relative paths absolute, remove trailing slashes,
etc. (fix issue#152)
* Check loaded modulefiles still exists before displaying statistics
on them during a "list" action.
* Use a specific reference counter variable name
("MODULES_MODSHARE_<VAR>" instead of "<VAR>_modshare") for DYLD-
specific variables. (fix issue#153)
* No error raise when updating a DYLD or LD path-like variable on OS
X when System Integrity Protection (SIP) is enabled. In this
situation, these variables are not exported in subshell context, so
they appear undefined.
* Init: protect arguments passed to the "_moduleraw" sh function
from interfering content of current working directory. (fix
issue#154)
* Install: move "hostname" RPM requirement to the compat sub-
package.
* Start pager process only if some text has to be printed.
(partially fix issue#146)
* Ignore "PAGER" environment variable to configure Modules pager to
avoid side effects coming from a general pager configuration not
compatible with Modules pager handling. (fix issue#146)
* Do not blank anymore default Modules pager options if default
pager is "less" when the "LESS" environment variable is defined.
(fix issue#146)
Warning: With this bugfix release, changes have been made on the
pager setup to avoid side effects coming from the system general
pager configuration. As a result "PAGER" environment variable is now
ignored and "MODULES_PAGER" should be used instead to adapt Modules
pager configuration at run-time.
Modules 4.1.0 (2018-01-15)
==========================
* Extend stderr output redirection on sh-kind shells to all
terminal- attached shell session, not only interactive shell
session.
* Extend shell code produced by the "autoinit" command to perform
the same environment initialization as done in "init" shell scripts
(default value set for module-specific environment variables, parse
or source of configuration files).
* Make init shell scripts rely on "autoinit" command to define the
"module" command and setup its default environment.
* Fix error rendering code for Tcl shell by producing a call to the
"error" procedure.
* Introduce pager support to handle informational messages, using
"less" command with "-eFKRX" options by default. Environment
variable "MODULES_PAGER" or "PAGER" may be used to supersede default
pager command and options. "--paginate" and "--no-pager" switches
enable or disable pager from the command line.
* Install: add "--with-pager" and "--with-pager-opts" configure
options to define default pager command and its relative command-
line options.
* Introduce quarantine mechanism to protect module execution against
side effect coming from the current environment definition.
Variables whose name has been put in "MODULES_RUN_QUARANTINE" will
be emptied or set to the value hold by "MODULES_RUNENV_<VAR>" in the
modulecmd.tcl run-time environment. Quarantine variable original
value is then restored within modulecmd.tcl execution context once
it has started.
* Install: add "--with-quarantine-vars" configure option to define
at build time the "MODULES_RUN_QUARANTINE" and
"MODULES_RUNENV_<VAR>" environment variables set in initialization
scripts.
* Add "MODULES_SILENT_SHELL_DEBUG" environment variable to disable
on sh shell and derivatives any "xtrace" or "verbose" debugging
property for the duration of either the module command or the module
shell initialization script. (fix issue#121)
* Change error code produced by modulecmd.tcl for the Tcl, Perl,
Python, Ruby, CMake and R scripting languages to return a 'false'
boolean value in case of error rather raising a fatal exception.
* Adapt module function definition for Tcl, Perl, Python, Ruby,
CMake and R scripting languages to always return a value, result of
the modulecmd.tcl run. When modulecmd.tcl run does not produce a
specific status, a 'true' boolean value is returned. On CMake,
resulting value is returned though a "module_result" global
variable.
* Spool content sent to the stdout channel with "puts" command
during a modulefile interpretation, to effectively transmit this
content to stdout after rendering the environment changes made by
this modulefile. (fix issue#113)
* Introduce "append-path", "prepend-path", "remove-path" and "is-
loaded" module sub-commands, based on existing modulefile-specific
Tcl commands. (fix issue#116)
* Introduce "is-saved", "is-used" and "is-avail" modulefile Tcl
commands and module sub-commands to test availability of collection,
modulepath or modulefile.
* Raise error when a call to "path" or "paths" module sub-commands
is attempted during a modulefile interpretation. Both commands now
return text rather print text on scripting languages. An empty
string is returned in no match case instead of a false boolean
value.
* Introduce "module-info loaded" modulefile command and its module
sub-command counterpart "info-loaded". This new command returns name
of the modules currently loaded corresponding to the name passed as
argument. (fix issue#3)
* Fix "is-loaded" command to correctly handle multiple module names
passed as argument (fix issue#138)
* Support no argument on "is-loaded", "is-saved" and "is-used"
commands to return if anything is respectively loaded, saved or
used.
* Interpret "module source" command set in modulefile in "unload"
mode when the modulefile itself is interpreted in this mode.
* Consider a modulefile passed with name starting by "./" or "../" a
full path name modulefile, like those starting by "/". These kind of
names are converted to absolute path names, for instance to register
them in loaded modulefile list during a "load" command.
* Correlate modulefile passed as full path name (starting by either
"./", "../" or "/") to already loaded modulefile registered with
regular module name (file name without its modulepath prefix) to
prevent for instance from loading twice same modulefile. Correlate
in the same way regular module name to already loaded full path name
modulefile.
* Introduce "MODULES_COLLECTION_PIN_VERSION" environment variable to
record modulefile version number when saving collections even if
version corresponds to the default one. (fix issue#89)
* Fix location of "etc/rc" global RC file to "@prefix@/etc/rc"
instead of "$MODULESHOME/etc/rc" not to depend on "MODULESHOME"
environment variable value.
* Strengthen argument check for "append-path", "prepend-path" and
"remove-path" modulefile Tcl commands and module sub-commands. Raise
error if argument list is not correct.
* Fix support for the "--delim=C" argument form on "append-path",
"prepend-path" and "remove-path" commands.
* Fix path reference counter handling in case path element is an
empty string. Distinguish an empty path element from a variable set
empty to clear it.
* Pass multiple path elements separated by delimiter character as
one string on "append-path", "prepend-path" and "remove-path"
commands.
* Accept multiple path element arguments on "append-path", "prepend-
path" and "remove-path" commands.
* Introduce the "--duplicates" argument option to "append-path" and
"prepend-path" commands to add a path element already registered in
variable.
* Introduce the "--index" argument option to "remove-path" command
to delete a path entry by passing its position index in variable.
* Provide the ability to setup a site-specific configuration sourced
at the start of "modulecmd.tcl" main procedure. This configuration
is a Tcl script named "siteconfig.tcl" which enables to supersede
any Tcl definition made in "modulecmd.tcl". Location of this file is
controlled at configure time with the "--etcdir" option.
* Add the ability to handle paths containing reference to
environment variable in "MODULEPATH". When these kind of paths are
used by "module" command, the variable references are converted to
their corresponding value or to an empty string if they are not
defined.
* Enclose value set to environment variable on Tcl within curly
braces rather double quotes to protect special characters in it from
interpretation.
* Correctly parse ".modulespath" initialization file to handle lines
without any "#" character or to handle files with no content to
extract.
* Re-introduce the "--enable-versioning" configure option, which
appends Modules version to installation prefix and deploy a
"versions" modulepath shared between all versioning enabled Modules
installation. A modulefile corresponding to Modules version is added
to the shared modulepath and enables to switch from one Modules
version to another.
* Fix removal of CMake generated temporary script file by stripping
newline character from script file name.
* Add "MODULES_CMD" environment variable to expose path to the
currently active module command script. This variable is set at
initialization time.
* Introduce "modulecmd" wrapper script, installed in binary
directory, which executes the active module command.
* Fix modulefile Tcl interpreter reset when handling list variables.
(fix issue#145)
* Introduce 'module-virtual' modulefile Tcl command to associate a
virtual module name to a modulefile. This module can be located with
its virtual name and the associated modulefile is the script
interpreted when loading, unloading, etc.
* Resolution of relative paths occurring during a modulefile
interpretation to target a modulefile or a modulepath now takes the
directory of the currently interpreted modulefile as the current
working directory to solve the relative paths.
Modules 4.0.0 (2017-10-16)
==========================
Starting with this release, modules-tcl has become Modules. The
following changes describe the differences with last modules-tcl
release (1.923). To learn about the changes between this release and
last Modules 3.2 release, please see the MIGRATING document.
* Relax constraint on command-line argument position so options and
switches can be passed either before or after command name.
* Report "unsupported option" warning rather stop on error when
compatibility-version specific command-line switches are passed ( "
--force", "--human", "--verbose", "--silent", "--create", "--icase",
"--userlvl").
* Keep empty "module load" line in shell configuration files after
running the "initrm" or "initclear" commands.
* Always return the value of "tcl_platform(osVersion)" for "uname
release"
* Optimize code output, for Perl to only return "1;" once for a no-
operation situation and for Python to not "import os" when there is
only an error to render.
* Use value of system command "uname -n" for "uname nodename".
* Add support for CMake *shell*
* Ignore "/" character used as suffix in modulefile name passed on
command line.
* Rename Perl initialization script in "perl.pm" and Python in
"python.py".
* Add support for Ruby *shell* (with contribution from Tammo Tjarks)
* Add support for R *shell* (with contribution from Roy Storey)
* When a *default* is set for a given module name, target modulefile
can be referred on as *modulename/default* in addition to just
*modulename*.
* Locate symbolic versions on "avail" command even these symbols are
set over a module alias or another symbolic version. In this
situation the symbol spread along the resolution path until reaching
a modulefile.
* Define a more standard shebang on modulecmd.tcl script.
* Determine modulefile corresponding to given module name using the
loaded context only on "unload" situation.
* Enable to unload *mod/dir/subdir/vers* when unload of *mod* or
*mod/dir* asked. Was previously working only if deep module to
unload was also the default version for these root names.
* Make -l/-t switches mutually exclusive. Last switch mentioned on
the command-line is honored.
* Output parsable modulepath header when -l/-t switches are enabled.
* 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.
* Solve aliases or symbolic versions looking for all modulepaths on
"search" and "paths" commands. Was previously solved if their target
was found in same modulepath directory.
* Add support for hidden *dot* modulefiles. A hidden modulefile does
not appear in case of wild search, it is only returned when search
is about its exact name.
* No table header print in --long mode on an "avail" command if no
result are returned.
* Add blank line between displayed list of elements, for instance
between modulepath content on "avail" command.
* Improve readability of error messages encountered during
modulefile execution by putting Tcl error message first after the
"Module ERROR" prefix.
* Do not exit immediately when an internal error occurs in currently
interpreted modulefile. Consider this interpretation as failed and
continue to proceed the other modulefile arguments.
* When multiple modulefiles are passed on "display", "help" and
"test" commands only output one separator line between 2 interpreted
modulefiles.
* Fix environment settings stack handling issue when restoring stack
after a failed attempt to load a modulefile in a modulefile.
* Failed attempt to load or unload a modulefile within a modulefile
now leads to this upper modulefile load or unload failure.
Previously upper modulefile were loaded respectively unloaded even
if its dependent sub-modulefile failed to load or unload.
* During a "switch" command, if the unloading part fails the loading
part will not be tried. Unloading part fails if module to unload
does not exist or its unload interpretation raise error.
* Init: use "module source" rather shell command "source" to load
modulerc system configuration in sh-kind, csh-kind and fish shell
init scripts.
* Install: transform configuration options to bind to an existing
compatibility Modules version into option (--enable-compat-version)
to build and install this compatibility version along with main
version.
* Init: adapt initialization scripts to handle both main and
compatibility version. By default a shell script enables main
version and if the environment variable MODULES_USE_COMPAT_VERSION
is set to 1, the compatibility version is enabled instead of main
version.
* Install: import from compatibility version and install
"add.modules" and "mkroot" utility scripts (scripts developed by
R.K. Owen).
* Install: update RPM spec file to handle compatibility version as a
"compat" sub-package.
* Add completion script for Fish shell (contribution from BEFH).
* Doc: extend content of diff_v3_v4 to details all noticeable
changes between v3.2 and v4.0.
* Doc: introduce MIGRATING guide to learn the major changes when
moving from v3.2 to v4.0.
* Fix "list" command when full pathname modulefile is loaded (fix
bug#132)
* Install: handle version number though git tags in scripts,
documentation and RPM spec file.
* Doc: migrate documents from POD format to reStructuredText to
benefit from Sphinx documentation framework and Read The Docs
publishing capabilities.
Above changes describe the differences with modules-tcl release 1.923.
To learn about the changes between Modules 4.0 and last Modules 3.2
release, please see the MIGRATING document.
modules-tcl-1.923 (2017-07-20)
==============================
* Fix "aliases" command when a global or user RC file is set.
* Find and solve global or user RC aliases and symbolic versions on
"search", "whatis" and "paths" commands.
* Do not look at currently loaded modules to resolve the target of a
module alias.
* Rework default and latest versions search on "avail" command.
Correct display 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 latest versions at the same level). A directory tagged
"default" does not appear anymore in default listing result as its
content (the default version found in that directory) will be
displayed.
* When an alias is set and overrides name of an existing directory,
take this alias into account for default and latest choice and
ignore directory content.
* Bad default set will lead to no result displayed for the
corresponding module in case of default "avail" display.
* Correct inclusion of aliases in output result when these aliases
are not part of the exact same module path than module path of the
search.
* Rewrite existing shell initialization file with initadd,
initprepend, initswitch, initrm and initclear commands rather than
writing a new file then copying this new file to replace the
existing initialization file. In addition only re-writes shell
initialization file if its content need to be altered.
* Raise an error on initadd, initprepend, initswitch, initrm and
initclear commands when no "module load" line are found in shell
initialization file.
* Normalize error messages for the various collection-related
commands when collection cannot be accessed.
* Cleanup existing reference counters of a path list variable when
this variable is altered by a "setenv" or an "unsetenv" command.
* Init: do not pollute tab-completion with moduleraw command. (Bert
Wesarg)
* Make use of the same Tcl interp for each modulefile interpretation
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 achieved with this change on
commands making intensive use of interp like "avail". Interpreter
state is reset from one interpretation to another: the initial
variable and procedure state is restored before each new
interpretation to avoid spread of definitions from one
interpretation to another. Also in case of nested interpretation
each interpretation level has its own interpreter so a module loaded
by another does not influence the interpretation of the module
loading it.
* Improve performance of aliases and symbolic versions resolution by
computing these resolution at definition time. As a consequence
resolution loop are not registered anymore and produce an error
message when spotted not at display time.
* Reduce number of "access" system call by trying access to
modulefile when reading the content of a modulefile directory rather
testing access before trying it.
* No error raise on empty argument list for load. To cope with
initadd behavior that requires at least an empty "module load" line
in startup files. (fix SF bug#88)
* Fix initadd to handle load line without trailing space. Was
previously expecting load directive to be written "module load " to
get a match. With fix, "module load" line will also be matched.
* Like C-version catch raised error when break or continue are
called from outside of a loop to handle them as when they are called
from modulefile main body. (fix SF bug#87)
* Return error on "module use" command when an empty path string is
provided rather ignoring it.
* Workaround "min" and "max" functions and "lreverse" procedure for
correct operations under Tcl version 8.4.
* Install: add --with-tclsh configure option to give the ability to
choose the Tcl interpreter shell to setup in initialization scripts.
* Handle error raised from the ModulesDisplay, ModulesHelp and
ModulesTest procedures in the same way than for the evaluation of
the modulefile content. An error occurring during the evaluation of
the modulefile content will lead to no evaluation of the "display",
"help" and "test" command specific functions.
* Remove "debug" module command
* Doc: describe "path", "paths" and "autoinit" module command.
* Correct use of xrdb tool when not installed in default path.
* Fix "init*" module commands to behave more like C-version and
document remaining differences in diff_with_c-version.
* Init: make "sh" init script closer to POSIX specification to
support sh flavors different than Bash or Zsh like Dash.
* Fix column-mode display for very short width terminal.
* Install: introduce an "install" non-regression testsuite which is
triggered by the "make testinstall" command and checks modules-tcl
installation is operational.
* Init: fix modulerc load test on "fish" init script.
* Init: fix interactive shell test on "sh" init script.
* Install: add --enable-example-modulefiles configure option that
install by default some modulefiles provided as example in the
system modulefiles directory.
* Install: when uninstalling, do not remove modulefiles directory if
it is not empty.
* Add completion script for Zsh shell.
* Add "module test" command to trigger when called execution of a
ModulesTest procedure in target modulefile following same kind of
mechanism than "module help".
modules-tcl-1.832 (2017-04-29)
==============================
* Fix "getenv" sub-command to correctly return environment variable
value.
* Clarify in man-pages display of module alias and symbolic version-
name on "avail" command and management of file access issue when
locating modulefiles.
* Distinguish access issue (permission denied) from find issue
(cannot locate) when trying to access directly a directory or a
modulefile as done on "load", "display" or "whatis" commands. In
addition on this kind of access, not readable .modulerc files are
ignored rather producing a missing magic cookie error.
* 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 unload the modulefiles in the reverse order
than they have been loaded.
* Correct "display" command to only report module commands set in
modulefile and not those set in the various .modulerc on the path
toward this modulefile.
* Fix bash and tcsh completion scripts to eliminate symbolic version
names from "avail" command result.
* Improve "avail" command when a symbolic version-name is passed as
argument to return the modulefile target of this symbolic version-
name.
* When looking for an implicit default in a directory, now a module
alias is taken into account so it can be returned as the last
element in it (highest numerically sorted version).
* Fix "list" command to correctly display the "default" tag along
loaded modules when set via a .version file.
* Fix long output of "list" command to display the symbolic version-
names associated to each loaded module if any.
* Improve "avail" command to return alias module when an alias name
is passed as argument.
* On a "--default" listing, a modulefile does not appear anymore if
a directory is set default at the same level. On a "--latest"
listing, a directory does not appear anymore if set default but not
the latest.
* Read modulerc and validate its header in a single open/read/close
sequence instead of two in order to reduce to number of IO
operations during an "avail" command.
* Drastically reduce grid size computation time which removes
overhead when displaying module avail results in column-mode.
* Translate module name to currently interpreted module name when
name correspond to the last part this interpreted module only in
case of symbolic version-name or alias resolution.
* Avoid resetting regular path (/usr/bin) or manpath
(/usr/share/man) when switching from Tcl to C version in switchml
utility.
* Raise error on x-resource if DISPLAY environment variable is not
set.
* Fix lisp init script which was broken for environment change
actions.
modules-tcl-1.775 (2017-03-07)
==============================
* Improve README with examples, requirements, links, etc. Also
update INSTALL documentation with details on the new
configure/make/make install process.
* Add display of a release date next to the version number when
calling for "--help" or "--version".
* Update diff_with_c-version document to describe the features of
the Tcl-version that are not supported on the C-version. Also state
that the diff takes C version 3.2.10 against Tcl version 1.729 as a
basis.
* Introduce "switchml" tool, a shell function (or alias for csh or
tcsh shells) that swap currently enabled Modules version (C or Tcl)
by the other version (C or Tcl). Configure option "--with-cver-
initdir" must be defined to enable "switchml" in initialization
script.
* Define a PATH and MANPATH in shell initialization scripts that
point to the defined modules-tcl installation directories.
* Give ability to generate distribution tarball from the git
repository with Makefile "dist" target.
* Introduce an installation process for this software following the
configure/make/make install fashion. Configure step enables to
choose installation paths and init scripts features to activate.
Make step mainly translates init scripts with the configuration set.
Make install creates target directories and copy files into them.
* Fix MODULESHOME setup in autoinit command to define it as an
absolute path and set it to the upper directory when modulecmd.tcl
is located in a "bin" or a "libexec" directory.
* Correct alias and version resolution on avail command which was
erroneous in case of a modulefile holding symbols (like "default")
and targeted by aliases. Avail output was showing the aliases
holding the symbols instead of the modulefile.
modules-tcl-1.729 (2017-02-01)
==============================
* Add documentation in module(1) man page on the modulefile
collection concept and the relative "save", "restore", "saverm",
"saveshow" and "savelist" commands.
* Add document to list the differences of the functionalities that
can be found on the C-version of the Modules package compared to the
Tcl-version.
* Improve modulecmd.tcl shebang to only search "tclsh" once if found
in PATH.
* Add "module-info mode" check against "remove" and "switch" values.
* Introduce "module-info command" Modules-specific Tcl command to
distinguish complex "load" or "unload" commands that cannot be
determined with "module-info mode" alone. For instance a modulefile
can now be aware that a "switch", a "restore" or a "purge" command
is currently being run.
* Enable usage of "module-info" Modules-specific Tcl command from a
modulerc file.
* Fix "module-info specified" Modules-specific Tcl command.
* No exit raise on modulefile or modulerc error during "avail",
"aliases", "whatis" and "search" commands to avoid harming results
from these global commands if error exists in a few modulefiles.
* Exit with error code when a critical error is encountered when
interpreting a modulefile or a modulerc.
* Inhibit non-critical error report raised from modulefiles during
"avail", "aliases", "whatis" and "search" commands to avoid error
flood when parsing all modulefiles or modulercs.
* Handle multiple lines of "module-whatis" Modules-specific Tcl
commands defined for the same modulefile.
* Handle multiple arguments passed to the "module-whatis" Modules-
specific Tcl commands. They are joined to get a single line of text.
* Return error on "whatis" command if searched modulefile is not
found.
modules-tcl-1.704 (2017-01-20)
==============================
* Set path variable counter to 1 for paths without a known reference
count (was previously set to 999999999).
* Introduce "envml" utility which acts as an application launcher
where module commands are instantiated to setup environment before
launching the given application.
* Always register paths provided to be part of MODULEPATH
environment variable as absolute paths to get independent from the
current working directory.
* Inhibit next modulefiles interpretation with "exit" Modules-
specific Tcl command only if current mode is "load".
* Add argument to "module-info shell" and "module-info shelltype" to
test current shell or shelltype value.
* Fix use of "default" version-name to not consider it as a module
symbol if a modulefile is named "default".
* Fix path variable counters when ":" character is used in elements
of a path-like variable.
* Update module(1) and modulefile(4) man pages to clear content
specific to the C version of Modules and add content specific to or
adapt content that behave differently on this Tcl version.
* Fix TCLSH variable issue in Python init script.
modules-tcl-1.677 (2017-01-04)
==============================
* Make "switch" command handle a single argument. The modulefile to
switch to is the one passed on the command-line and the modulefile
to unload is assumed to be the currently loaded module with the same
root name as this modulefile specified on the command-line.
* Make "switch" command idempotent by always ending up with "old"
unloaded and "new" loaded, whatever the starting situation is.
* Fix "exit" Modules-specific Tcl command.
* Add "refresh" command as alias on "reload" command.
* Add dummy "module-log", "module-trace", "module-user" and "module-
verbosity" Modules-specific Tcl commands to enable support for
modulefiles using them.
* Fix "system" Modules-specific Tcl command to behave like
described on the man page.
* Fix "module list" when module loaded with full path
* Disable "g_force" property by default to avoid loading a
modulefile already loaded. It also avoids path element reference
counting to get increased when the same module is asked twice for
load.
* Clarify module-info "mode" option and set "help" mode on "module
help" command.
* Clarify module-info "flags" and "user" options.
* Handle empty or separator path on "add-path" ad "unload-path"
commands.
* Delete environment variable targeted by an "unsetenv" command on
"unload" mode if no value has been provided along. On display mode,
print environment variable value if any has been passed to
"unsetenv" command.
