This file describes changes in recent versions of modules-tcl. It primarily
documents those changes that are of interest to users and admins.
Changes in 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.
Changes in 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.
Changes in 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.
Changes in 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.
* When setting Tcl variable, enclose value within double quotes.
* Fix perl quoting style for variable set, escape single quotes rather
double quotes.
* Call 'unuse' command instead of 'use' command on a 'module unload'.
* Fix 'continue' Modules-specific Tcl command.
* Add 'chdir' Modules-specific Tcl command.
* Fix 'break' Modules-specific Tcl command.
Changes in modules-tcl-1.655 (2016-11-23)
-----------------------------------------
* No display of modulepath header if no module found in it.
* Remove call to 'module aliases' on 'module avail' command, as aliases
are now directly included in the 'avail' results.
* Include module aliases in the displayed result of an 'avail' command.
Also display aliases defined in a global or user modulerc file.
* Exit with error code if error occurred on display or help commands.
* Fix module-info symbols resolution.
* Better handling of .modulerc and .version files when searching for a
modulefile.
* Fix module-info version resolution.
* Fix module-info alias resolution.
* Register alias and version by the short module name and improve their
resolution to avoid loop.
* Source $MODULERCFILE/modulerc when $MODULERCFILE is dir.
* Make it so you can do 'module avail un', wildcard '*' character implied.
Changes in modules-tcl-1.632 (2016-09-06)
-----------------------------------------
* Raise error if command does not receive the excepted number of arguments.
* Improve column-mode display to get a denser output on 'avail' command.
* Standardize the output of Warning, Error, InternalBug and ErrorAndExit
messages.
* Add short option -d for --delim on prepend-path.
* Introduce collection target concept to distinguish between machines,
environments or domains that are incompatible with each other.
* Introduce 'saveshow' command, to display content of saved collections.
* Improve 'save' and 'restore' commands to handle collection specified as
absolute or relative file path.
* Introduce 'saverm' command, to delete saved collections.
* Enable to 'restore' collection with multiple modulefiles specified on the
same line.
* Fix 'restore' command when there is no module to load in collection.
* Fix 'restore' command when collection fully rewind module paths.
* Fix 'restore' command to preserve module path order set in collection.
* Raise error if try to save an empty environment in a collection.
Changes in modules-tcl-1.602 (2016-08-13)
-----------------------------------------
* Add support for Fish shell.
* Import recent tests added to C-version on 10-use and 50-cmds testsuites.
* Add short option -d for --delim on append-path and remove-path.
* Fix load and implement unload x-resource.
* Fix Python code that was broken or not Python3-compliant. Fixed code is
used to define the module command, to render error and to process
x-resource.
* Always dictionary-sort (also called numerical-sort) list of modulefiles
or list of collections.
* Fix bash completion script to be compliant with bash posix mode.
Changes in modules-tcl-1.578 (2014-12-24)
-----------------------------------------
* First release to be described in this NEWS file but it does not mean this
is the first version of modules-tcl as this Modules flavor is born in
2002.
* At this stage, modules-tcl handles a majority of the module commands and
modulefile Tcl commands available on C version.
