Notes

• Issue #679: dynamic LMOD_MODULERC and downstream conflict support open for testing

  • Support for downstream conflicts was complicated but sees to work
  • Support for dynamic LMOD_MODULERC support was even harder.
  • It required completely reworking how defaults where stored.
  • This features allows modulefiles to set LMOD_MODULERC to point to a new list of module_version("name/version","default"). It replaces any previous LMOD_MODULERC files.

• Issue #680: Honor MODULES_AUTO_HANDLING:

  • Work continues on this: Support for converting prereq() to depends_on () is easy.
  • Support for depends_on_any() is now complete.
  • This is ready for testing.

• A couple of issues with use of os.getenv() or using env. vars. between modulefiles

  • Both of these can fail on unloads.
  • directly prepend_path() is a bad idea: New FAQ
  • os.getenv("VAR") returns nil if $VAR doesn't exist.
  • Use os.getenv("VAR") or "" to be safe.

• Issue #686: generate a man page for module

  • Lmod generates a *.pod format if pod2man is found
  • pod2man is used to build the man page.

• A user requests support for NUSHELL -> user requested to create PR.

• New feature added: $MODULEPATH changes are now remembered in the ModuleTable

  • This way if a modulefile disappears the changes in $MODULEPATH are correct.
  • This affects loading of collections.

• How to handle \u like in prompts -> \u (New FAQ entry)

• Will look at requests for different ways to mark hidden modules.

• Release of Lmod 8.7.44

• Robert described working on Lmod Design doc. Fotis recommended using https://gitlab.com/gitlab-org/gitlab/-/issues/241744 for better diagrams.
