Re: [Modules] `module use --append` and `append-path MODULEPATH` replace centrally set MODULEPATH instead of appending to it

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

The etc/modulespath and etc/initrc configuration files are evaluated during
Modules initialization only if MODULEPATH and LOADEDMODULES environment
variables are found unset or empty.

When a module command is run, the ~/.modulerc file is evaluated. It happens
also for the autoinit command, which is run to initialize Modules.

So in your situation, during the initialization of Modules, MODULEPATH is
defined by ~/.modulerc commands, so the etc/modulespath file is not
processed.

I would recommend not to set MODULEPATH in ~/.modulerc file
(etc/modulespath, etc/initrc or collection files should be preferred to
define the modulepaths). But one way to workaround this issue is to update
~/.modulerc with the following code:

$ cat ~/.modulerc
#%Module
if {![module-info command autoinit]} {
   module use --append /a/b/c
   append-path MODULEPATH /d/e/f
}

Cheers,
Xavier
