hide-version works as intended, but crippled clean shell startup on qrsh submission

this could well be caused by Tcl modules, as opposed to Lmod, since we're dual stacked; this really looks as module language incompatibility, which hints at need for different markup for hidden bits

[rtmclay]

This error is coming from Tmod not Lmod. You'll have to wrap the hide-version command to hide it from Tmod. You should try something like this in your \~/.modulerc file:

#%Module
global env
if { [info exists env(LMOD_VERSION_MAJOR)]} {
    hide-version CUDA/8.8.8
}

It is clear that the error messages came from Tmod as it said it came from cmdModule.c(613): ... You'll never see an error like that from Lmod.

Lmod defines LMOD_VERSION_MAJOR during its execution and nowhere else you can use it to know that Lmod is processing a TCL file.

[rtmclay]

I have added to http://lmod.readthedocs.io/en/latest/040_FAQ.html to report the same information on how to have Lmod only code in a TCL file that might be read by Tmod.

@rtmclay : this was helpful, thanks!

Since I am conditional-clauses-averse I'd like to query, out of curiosity, if there could exist any alternative mechanism which is simply ignored by Tmod but understood by Lmod. fi. it could be a parameter while loading a variable or something of the sort.

Not asking for any implementation, just checking for future needs! ;-)

[fgeorgatos]

OK, false alarm on this one: this occured via the headnode which had no Lmod RPM, so it fall back to Tmod, as it should. Closing issue,
