Lmod Version 5.8
Features/Bug fixes:
a) Lmod support auto swapping instead of producing an error.
b) The init/bash.in and init/cshrc add a trailing colon to
MANPATH if it is empty
c) Fixes bug in ml tab completion for zsh.
d) setenv, prepend_path, etc now trim any leading or trailing
blanks around name: prepend_path(" MANPATH ","/opt/apps/...")
is now the same as prepend_path("MANPATH","/opt/apps/...")
e) The module command (and not ml) support combining of single
letter options. "module -dw=60 avail" is the same as
"module -d -w=60 avail".
f) If a module collection file gets corrupted, Lmod now reports
that the collection file is corrupted and tells the user to
remove it.
g) Lmod now support "module swap <name>" which is exactly the
same as "module load <name>". The module <name> is unloaded
and then reloaded.
h) Sites can configure for exporting the module shell function
in bash or not.
Lmod Version 5.7.5:
Features/Bug fixes:
a) "module use" and "ml use" now will work with tab completion
under bash. (It worked before for zsh).
b) New option, --spider_timeout sec is added. Reason: When
Lmod can not load a module, it does a module spider to
see if the module exists but isn't loadable. Now Lmod
doesn't do the spider when in LMOD_EXPERT mode. It also
times out after 2 seconds. If Lmod can't tell you quickly
if a module exists, why do it.
c) New configuration option --with-ignoreDirs. By default
Lmod will ignore directories named .svn, .git, .hg and .bzr
in the Module directories. If you use CVS, RCS or SCCS to
source control your modulefiles, you will need configure
Lmod to know about those directories.
d) New avail hook added. You can regroup the output of avail.
The avail hook gets a table of current directories that avail
will list. Your routine can relabel them. The input looks
like this:
t = {
['/path/to/IntelCmp/mfiles'] = "/path/to/IntelCmp/mfiles"
['/path/to/core/mfiles'] = "/path/to/core/mfiles"
}
Your routine can relabel and change the labels
t = {
['/path/to/IntelCmp/mfiles'] = "Compiler Dependent"
['/path/to/core/mfiles'] = "Core Modules"
}
You can also group them
t = {
['/path/to/IntelCmp/mfiles'] = "Modules"
['/path/to/core/mfiles'] = "Modules"
}
In the last case intel modules and core modules will be
grouped together.
e) Better handling of zsh tab completion files. Lmod will
continue to install even when a site's zsh setup is
broken.
f) New option, --show_hidden, has been added. This is used
with avail to show "hidden" modulefiles. That is module
files that start with a "."
Lmod Version 5.7.4
Features/Bug fixes:
a) Improved support for redirecting output to stdout. Now show,
and help will write to stdout if LMOD_REDIRECT=yes.
b) module show unknown will set the return error code if "unknown"
doesn't exist.
c) "module --terse spider phdf5" will now produce a terse output.
d) a module file can do setenv("FOO","") and set the env.var to an
empty string.
e) Support for empty strings "" in paths are better supported.
Lmod Version 5.7.2
Features:
a) This version supports (an optional) sending the output of avail, list,
spider and keyword stdout instead of stderr. This available as a
configure option, an environment variable (LMOD_REDIRECT=yes) or
module --redirect avail.
Note that if you use this option the internal pager is off.
Lmod Version 5.7
Features:
a) Lmod is now more efficient when loading and unloading
modulefiles that modify MODULEPATH when there is no
cache file.
b) Lmod now reports that lua-term is active or not when
"module --config". This is there so that if Lmod is
built on a system that as a system lua-term on one and
is installed on a different system that doesn't.
c) module spider now reports module version in "parseVersion"
order. (i.e 0.7.10 is newer than 0.7.2)
d) Internally Lmod sets LC_ALL=C so that a user's Locale does
not effect its behavior.
Bug Fixes:
a) Lmod can now handle TCL modulefiles that use
"puts --nonewline ..."
b) TCL whatis with multiple arguments is now correctly handled.
c) Changed require("posix") to local posix=require("posix")
Lmod Version 5.6.3
Bug Fixes:
a) Lmod now correctly handles prepending multiple directories to
MODULEPATH in one prepend_path.
Lmod Version 5.6.2
Bug Fixes:
a) LMOD_EXPERT is now also turns on quiet mode. It was removed
accidently in 5.6.1 and is now restored.
b) Lmod had a bug where it tracked prereq, conflict and family
commands in module collections where it didn't need to.
This means that some users will have to rebuild their module
collections when they shouldn't have to.
Lmod Version 5.6.1
Features:
a) The environment variable LMOD_OPTIONS can be use to specify
command line options to LMOD: export LMOD_OPTIONS="--quiet"
b) The environment variable LMOD_PAGER can use to specify the pager
that Lmod will use, otherwise PAGER is used or "more"
c) the -q or --quiet option suppresses messages and warnings (but not
errors).
Bug Fix:
a) Executing "module list" when there no modules loaded is a message
and not a warning.
Lmod Version 5.6
Major Bug Fix:
Two bugs I have un-earthed cancelled each other all related to saved
collections. The upshot is that many users will have get a message
that they have to rebuild their collection because the modules have
changed. This isn't true but they will have to anyway. I now have
tests which will guard against this from happening again. I
apologize for this bug.
Bug Fixes:
a) Lmod is supposed to error out if the modules in a named
collection changed in a way such that the loaded modules would be
different from loading directly. This is fixed.
b) This version correctly handles prepending to the MODULEPATH outside
of Lmod
c) Lmod now correctly handles symlinks to a template in the same
directory. Lmod also support the three ways to mark a default
with this setup as well.
d) Lmod now correctly handles "module-info mode" command in tcl
modulefiles.
e) tcl2lua.sh improvements to supports Cray modules.
Feature:
a) Support for .modulerc in modulefile directory only. This file can
be used to specify the default module only. No support for System
.modulerc or user ~/.modulerc
Lmod Version 5.5.1:
Bug Fixes:
a) Fixed bug where setting the priority twice caused an error. This is now
fixed.
b) A meta module that starts with "." will not seen by avail and spider.
Lmod Version 5.5:
Feature:
a) priorities can now be used with "module use":
$ module use --priority 100 /path/to/modulefiles
Bug Fixes:
a) Configuring on a system where tclsh is not found is handled better.
b) When doing module avail where MODULEPATH points only to non-existant
path it now reports that Lmod can not do a module avail.
Lmod Version 5.4.2:
Feature:
a) Sites with common home file system can use named collections that are
differentiated by LMOD_SYSTEM_NAME. This means that if the environment
variable LMOD_SYSTEM_NAME is set to "foo" then the default collection will
be saved to and restored from "default.foo". Other named collections work
the same way.
Bug Fix:
a) TCL modules can now have:
puts "message"
as well.
Lmod Version 5.4.1:
Added License file to tar ball.
Lmod Version 5.4:
Features:
a) prepend_path now supports a priority. This means that no matter when
a module is loaded a path will pushed to be first:
prepend_path{"PATH","/first",priority=100} -- lua
prepend-path PATH /first 100 # tcl
Note the use of {} braces for lua. The braces are only required when
specifying the priority, otherwise parens work fine. Priority works
for append_path as well. It just pushes paths to the right end. By
default, a path has a priority of zero. Paths will a priority of 100
are grouped together. Paths with a priority of 1000 are grouped
together to the left of the paths with a priority of 100. The priority
for prepend_path are useful for wrappers. The priority for append_path
is great for catch-alls.
b) Lmod now generates "LOADEDMODULES" and "_LMFILES_" to match TCL/C env.
modules.
c) Lmod now purges modules in reverse order that the module were loaded.
This helps when reading Cray modulefiles.
d) Lmod ships with lua-term and JSON4lua but will use the system lua-term
and lua-json if available.
e) added "--raw" to "module --raw show module". This just prints out the
"raw" modulefile.
f) Lmod now adds the env. var LMOD_SYSTEM_NAME to the user cache file. So
if LMOD_SYSTEM_NAME is Bar and on a intel system the cache file will be
~/.lmod.d/.cache/moduleT.Bar_x86_64.lua
g) To match TCL/C modules, the reverse of the module file commands
remove_path, unload, etc now does nothing rather-than producing an
error.
h) Support for a .version file with time to change the default:
#%Module1.0##################################################
set ModulesVersion "1.4.3"
set NewModulesVersion "1.6.5"
set NewModulesVersionDate "2014/04/25"
Note that the date is in yyyy/mm/dd format. This way it is neither an
American or European format.
i) To support both rpm and debian package rules, the system .settarg.lua
file is renamed to settarg_rc.lua. The .lmodrc.lua file has been
renamed to lmodrc.lua. User versions of these files remains the same:
".settarg.lua" and ".lmodrc.lua".
Bug Fixes:
a) There was a bug with avail and spider where it would not find modules
with a dash. This was fixed between version 5.2.3 and now.
b) There was a bug with "module -r spider "^phdf5/1.8.12$" where it would
say that the module wasn't there and yet it was. This has been fixed.
c) Improved the wording of "module load foo/1.2" when foo/1.2 existed and
when it didn't. (Thanks to Alex Moskalenko for the fix)
d) Lmod would do wrong when "module unload gcc mpich". It would make
mpich inactive. This is fixed.
e) Fixed bug where if there is a symbolic link to the modulefile it wouldn't
mark the default module correctly.
Lmod Version 5.3.2:
Bug Fix:
a) Fixed problem with symlink directories and picking the right default.
b) Fixed a bug where .version did not find the right default.
Lmod Version 5.3.1:
Feature:
a) added tool "sh_to_modulefile" to convert a bash shell script into
a lua based shell script.:
$ sh_to_modulefile -o intel-14.0.2.lua /a/intel/bin/iccvars.sh intel64
note that you can give argument to the shell script.
Lmod Version 5.3:
Features:
a) Searching for avail, spider and list are case-insensitive.
Lua regexp searching now requires a "-r" option
b) The modulefile function isloaded() takes atleast, between and latest:
isloaded(atleast("Foo","1.2"))
c) Spider searching improved. When an exact match is found Lmod reports
other possible matches:
R: R/2.1.5
Other possible modules matches:
PrgEnv, greenlet, parmetis, r
Bug Fix:
a) Quotes inside a whatis or help message are properly escaped.
b) Better handling of nested modules by fixing load order.
Lmod Version 5.2.4:
Feature:
a) Lmod can be configured to ignore TCL module files.
Lmod Version 5.2.3:
Bug Fixes:
a) Prereq now works with a version.
b) The function "always_load" works with show.
c) The "make install" now works and doesn't complain about not being a
git repository.
Lmod Version 5.2:
Features:
a) Modulefiles can mix load commands and setenv's and still be saved and restored.
b) In Lua modulefiles you can modify load function behavior:
load(atleast("a","1.2")) -- load module "a" with version 1.2
-- or higher.
load(between("b","1.2","1.4") -- load module "b" with version between
-- 1.2 and 1.4.
load(latest("c")) -- load latest version of "c", ignore
-- marked default.
This only works in Lua module files, and works on all load functions:
load, always_load.
c) In Lua modulefiles you can modify prereq function behavior:
prereq(atleast("a","1.2")) -- Module "a" must be version 1.2
-- or higher.
prereq(between("b","1.2","1.4") -- Module "b" must be version between
-- 1.2 and 1.4.
prereq(latest("c")) -- Module "c" must be latest possible
This only works in Lua module files, and works on all prereq functions:
prereq, prereq_any.
Lmod Version 5.1.5:
Bug Fixes:
a) Changes in the terse output for avail and spider. A directory
that contains module versions has a trailing "/"
b) The environment that a module sees (and only in that environment).
Lmod defines the following variables shown with their current values:
LMOD_VERSION: 5.1.5
LMOD_VERSION_MAJOR: 5
LMOD_VERSION_MINOR: 1
LMOD_VERSION_SUBMINOR: 5
c) Module function to do version comparison (only for lua based modulefiles):
if (convertToCanonical(LmodVersion()) > convertToCanonical("5.0")) then
-- Do something that is only valid for Lmod 5.0 or greater
end
The function convertToCanonical() knows how to deal with alpha, beta,
and rc version and the function LmodVersion() returns the current
version of Lmod.
Lmod Version 5.1.1:
Bug Fixes and internal improvements
a) Lmod can now find all the dot module files.
b) Fixed bug with inherit()
c) Settarg nolonger tries to control all TARG_* variables.
d) Better handling of "Rebuild cache ..." line.
e) Improvements to the execute function.
f) "module --mt" prints the module table
g) "settarg --stt" prints the settarg table.
Lmod Version 5.1.0:
Version 5.1.0 now supports the following new features:
a) module --ignore_cache which tells Lmod to ignore the cache even if it
exists.
b) module --config reports how lmod was configured.
c) Lmod no longer walks the directory tree on command like list and
unload.
d) The pager is now used only when TERM is defined and stderr is
connected to a tty (this includes a pty: pseudo tty).
e) The system startup scripts (init/profile, and init/cshrc) that
are usually linked to modules.sh and modules.csh in /etc/profile.d
contains now modulefiles: lmod and settarg. Please consider using
this as defined or moving these module files into your normal
MODULEPATH.
f) Support for settarg has been added for Bash, Zsh and Tcsh users.
g) See README.old for features added in earlier versions.
------------------------------------------------------------------------
What is Settarg?
------------------------------------------------------------------------
Settarg is new module that accesses a new tool to dynamically and
automatically updates "$TARG" and a host of other environment
variables. These new environment variables encapsulate the state of
the modules loaded.
*** NOTE ****
Please note that settarg feature is optional and is implemented as a
module. If and only if the settarg module is loaded you get the new
behavior. You can load and unload the settarg module at will to turn
on and off these new features. Settarg does work for tcsh users as
well a feat not to be scoffed at! Unfortunately regular csh is
missing necessary features for it to work.
*** NOTE ****
For example, if I have the gcc/4.7.2 module loaded
and the new settarg module loaded I get the following variables
defined in my environment.
TARG=OBJ/_x86_64_06_1a_gcc-4.7.3
TARG_COMPILER=gcc-4.7.3
TARG_COMPILER_FAMILY=gcc
TARG_MACH=x86_64_06_1a
If I change my compiler to intel/13.1.0, these variables change to:
TARG=OBJ/_x86_64_06_1a_intel-13.1.0
TARG_COMPILER=intel-13.1.0
TARG_COMPILER_FAMILY=intel
TARG_MACH=x86_64_06_1a
This was designed to help me as a developer of software applications
where I am constantly changing compilers, mpi stacks and other
modules. These variable are used to set the compiler flags and other
things in my Makefiles to control how my application is built. In my
case $TARG the directory is where the the objects, libraries and
executables are placed during the build process. It easy to have the
title bar reflect the dynamic state of your modules. You can
abbreviate items mentioned in the titlebar. I have found this
combination of settarg and Lmod to be a powerful development
tool. Even if this workflow is not yours, you may find parts of this
useful.
For a more complete tour of settargs features see:
contrib/settarg/Settarg.txt and the Make example in
contrib/settarg/make_example.
