Many thanks Roberto and Pierre-Olivier for your feedback. I will create 2 feature requests: one for "lua-to-mod" support and another for supporting Lua modulefiles (like Lmod supports Tcl modulefiles). Mixing Tcl and Lua modulefiles should not be too complex. Main pitfall to warn about may be regarding modulefiles that updates the environment then try to reach the content of this updated environment later-on. Lmod has this limitation with Tcl modulefiles (see https://lmod.readthedocs.io/en/latest/095_tcl2lua.html). But I think there should be a way not to be affected by such issue (I will try not to be affected by that in our Lua modulefile support). The other pitfall is that evaluating Lua files requires an extra evaluation process, as Tcl has to start Lua to perform evaluation. If done well, this extra cost should not be visible (resue same Lua interpreter for all evaluations). All of this are nice challenges to me. It may be part of the work of version 5.7 (the version after the next version), but we are not yet at the phase to plan the features of this future release. :-) Best regards, Xavier Le jeu. 20 févr. 2025 à 16:03, Pierre-O Q. <pio...@gm...> a écrit : > > Implementing a lua to mod translator would be great.

They might have warnings about that, or just state that it is a great idea. We should ask them, but I can state that it has been pretty useful for us in the past 10 years. We distribute our bioinfo software stack on a cvmfs setup. It is all tcl and most of the receiving hpc sites (all national sites in Canada) are running lmod and it works without flaws. > > Salutations, > Pierre-Olivier > > > > Le jeu. 20 févr. 2025, 9 h 10 a.m., InfnPi <rob...@pi...> a écrit : >> >> Personally i do not think that having an environment that has both modulefiles and lua files is a safe situation. >> If one decides to use modules you should only have modulefiles. >> Therefore i would not suggest to implement some sort of compatibility between the two systems as it is complicated and has to be correctly maintained when these tools evolve. >> >> Nevertheless i perfectly understand that it can happen that a site decides to use modules and has some inherited lua files that one would like to translate (once) in modulefiles supported syntax. >> So the best solution i could think of would be to implemente a separate program/command to translate lua configuration files into module configuration files, exactly as it is currently done by sh-to-mod. >> Therefore it would probably be nice to have also a lua-to-mod command to be used just for this use case. >> >> Roberto >> On 20 Feb 2025 at 07:36 +0100, Xavier Delaruelle <xav...@gm...>, wrote: >> >> Bonjour PIerre-Olivier, >> >> Modules does not currently support Lmod Lua modulefiles.
