Add capability to update `PS1` when loading the EESSI module #154

ocaisa · 2026-01-30T12:52:57Z

With this change you get

ocaisa@~/EESSI/software-layer-scripts(update_prompt_with_module)$ module load EESSI/2023.06
Module for EESSI/2023.06 loaded successfully
ocaisa@~/EESSI/software-layer-scripts(update_prompt_with_module)$ module purge
ocaisa@~/EESSI/software-layer-scripts(update_prompt_with_module)$ export EESSI_MODULE_UPDATE_PS1=1
ocaisa@~/EESSI/software-layer-scripts(update_prompt_with_module)$ module load EESSI/2023.06
{EESSI/2023.06} ocaisa@~/EESSI/software-layer-scripts(update_prompt_with_module)$

By requiring EESSI_MODULE_UPDATE_PS1 I've retained the original behaviour, but I do think the prompt change is nice (especially since EESSI is really an entirely different OS, it's good to aways know when you are inside).

init/modules/EESSI/2023.06.lua


+-- change the PS1 if it exists to indicate you have EESSI loaded
+-- (doesn't help with a csh or fish prompt, but we just live with that)
+if os.getenv("EESSI_UPDATE_PS1") then


I protected this so as not to change the current behaviour

…e-layer-scripts into update_prompt_with_module

I gave it a try on our cluster, but for some reason it doesn't work, the prompt doesn't get changed. I added an LmodMessage(prompt) right after that variable is initialized, then I get:

Lmod has detected the following error:  Unable to load module because
of error when evaluating modulefile:
     /home1/<myuser>/modules/EESSI/2023.06.lua: [string "help([[..."]:224: attempt
to concatenate a nil value (local 'prompt')

But it does exist:

[<myuser>@login1 modules]$ echo $PS1
[\u@\h \W]\$

bedroge · 2026-02-03T08:32:02Z

Looks like $PS1 is not actually forwarded to subprocesses, see https://unix.stackexchange.com/questions/288986/obtain-shell-prompt-in-python. Indeed, env | grep $PS1 doesn't work either, and neither does os.getenv('PS1') in Python. But why did it work for you? Did you use a different shell? Or did you manually set PS1 before testing this?

bedroge · 2026-02-03T08:41:48Z

Not sure how portable this is (only tested with bash), but something like this may work?

local prompt = capture("$SHELL -i -c 'echo $PS1'"):gsub("[\n\r]", " ")

edit: for some reason it doesn't work when loading EESSI/2023.06 again while it's already loaded.
