Re: [Modules] module use not working and unhiding modules

Hi list,

I have always made use of the "module use <path>" extension to customize modules depending on other modules.
To do this I put "module use --append <path>" in a top level module.

For example:
#%Module1.0#####################################################################
##
## python-3.7.7
##

set version 3.7.7
...
module use --append /mypath/to/python/$version

which then enables modules installed with python 3.7.7.
Now I want to use this in a combination with "module-hide" in >=4.6. And this is where things go wrong.

I can get all versions to work if I don't use "module-hide", but as soon as I use an rc file in etc/rc that contains some hiding stuff, then using "module use ..." in a module does not work.
I can't even get it to work by doing "module use <path>" on the command line (i.e. outside of a module).

The rc file contains something like this (plus additional stuff which *seems* irrelevant)
module-hide python@:2.7.17
module-hide python@3:3.7.6
module-hide python@3.8:3.8.3
module-hide python3@
module-hide numpy@:1.18.2

My python/3.7.7 module contains the above "module use --append" statement.
But that seems to clash with the hiding, but I can't see why?

Basically, if I don't have an rc file I get something like this (note the 2 sections)
 ----------------------------------------------------------------------- /zhome/0e/2/36189/dcc/env-modules/module-repo ------------------------------------------------------------------------
modules/4.3.1  modules/4.5.3  modules/4.7.1            python/3.2.5  python/3.4.1  python/3.5.4  python/3.6.2  python/3.6.10  python/3.7.6  python/3.8.0  python/3.8.2
modules/4.4.1  modules/4.6.1  python.scientific/3.8.4  python/3.3.0  python/3.5.1  python/3.6.0  python/3.6.7  python/3.7.5   python/3.7.7  python/3.8.1  python/3.8.4

----------------------------------------------------------------------- /zhome/0e/2/36189/dcc/env-modules/python/3.7.7 -----------------------------------------------------------------------
matplotlib/3.2.1  numpy/1.18.2  scipy/1.4.1

While if I have an rc file I get this (only 1 section)
 ----------------------------------------------------------------------- /zhome/0e/2/36189/dcc/env-modules/module-repo ------------------------------------------------------------------------
modules/4.3.1  modules/4.5.3  modules/4.7.1            python/3.2.5  python/3.4.1  python/3.5.4  python/3.6.2  python/3.6.10  python/3.7.6  python/3.8.0  python/3.8.2
modules/4.4.1  modules/4.6.1  python.scientific/3.8.4  python/3.3.0  python/3.5.1  python/3.6.0  python/3.6.7  python/3.7.5   python/3.7.7  python/3.8.1  python/3.8.4

I can't see why hiding modules should clash with module use...
Is there something I am missing?
I also tried renaming the python/$version folder to python-mods/$version, to no avail. Still only working without the rc file.

Hi Nick,

Could you send me the result of the following commands (after doing a module purge) :

$ module config --dump-state
$ module -DD load python/3.7.7
$ module -DD avail

Please send me these outputs as a direct message if you do not want to expose these details on the mailing-list.

Best regards,
Xavier
