Re: [Modules] Update PATHs after module load call inside modulefile

[Xavier D. <xav...@gm...>]

Hello Daniel,

Starting Modules 4.1, regular puts statement are run right after
environment changes, so the load phase in your example should perform just
fine:

$ cat foo
#%Module
append-path PATH /path/to/foo
puts "echo foo;"
$ $MODULES_CMD bash load ./foo
PATH=usr/local/bin:/usr/local/sbin:/usr/bin:/usr/sbin:/path/to/foo; export
PATH;
_LMFILES_=/home/user/foo; export _LMFILES_;
LOADEDMODULES=/home/user/foo; export LOADEDMODULES;
echo foo;
test 0;

For the unload phase, a new channel called prestdout is introduced to
render puts statement prior environment changes as the deactivate command
has to be done prior unsetting path. This is a new feature that will be
introduced in upcoming version 5.1 [1].

Regards,
Xavier
