Conference notes for 2022 08 02

Agenda for Lmod Zoom Mtg August 2, 2022

• Q/A
• Issue #585: Use install instead of cp? -> Lmod 8.7.11 change!
• Issue #584: Pushenv when used with TCL modulefiles
• Issue #594: change cp -p to cp in update_system_cache_files?
• sh_to_modulefile and source_sh() evaluate script with set -e: Silent errors
  • OpenFOAM's source script ($FOAM_BASH) does an unalias foo 2> /dev/null
  • if foo is not an alias, that fails => non-zero exit code
  • causes exit out of subshell used by sh_to_modulefile or source_sh() => silent error
  • fixed by appending || true to the unalias command in OpenFOAM script
  • script needs to be fixed in order to create module file for it with sh_to_modulefile or with source_sh()
• Bug Report Template at github
  • instructions for people to fill out issue can be "commented out" somehow?
• module --miniConfig
  • shows how your configuration is different from the Lmod default
  • somewhat similar to EasyBuild's --show-config (see https://docs.easybuild.io/en/latest/Configuration.html#overview-of-current-configuration-show-config-show-full-config)
• Lmod Zoom Mtgs notice added to lmod.readthedocs.io
  • maybe also announce Lmod monthly meetings on EasyBuild mailing list?
• Checking for valid env. var. names
