prompt not displaying in pixi shell

[twrightsman]

Checks

• I have checked that this issue has not already been reported.

• I have confirmed this bug exists on the latest version of pixi, using pixi --version.

Reproducible example

With export PS1="${PIXI_PROMPT}${PS1}" in .bashrc:

$ pixi shell
$

Issue description

I assume this is because $PIXI_PROMPT is not defined when the .bashrc is sourced, because it seems defined in the temp file sourced after the shell is started. Following this logic, running pixi shell twice leads to the prompt appearing:

$ pixi shell
$ pixi shell
(prompt) $

Expected behavior

$ pixi shell
(prompt) $

This is indeed a result of the change in how the shell works. You can do export PS1='$(echo $PIXI_PROMPT)'"$PS1" But that might give a really stange double result on the prompt.

Going to look into it asap, as this is properly broken.

Also a really nice improvement would be to use starship.rs, they have a really nice integration for conda aswell!

Found a way that works, but its not the shortest.

# Avoid overwriting other prompt commands (like the one from starship.rs).
if [[ -z $PROMPT_COMMAND ]]; then
    # Get original PS1
    export ORIG_PS1="${ORIG_PS1:-$PS1}";
    # Set the PROMPT_COMMAND to generate the prompt everytime before the prompt is created.
    export PROMPT_COMMAND='PS1="${PIXI_PROMPT}${ORIG_PS1}"'
fi

I tried the workaround but it broke the Conda prompt, just a heads up 😄

@twrightsman Ah thanks for testing, I'm not sure what the issue is. Could you share the result you get in your terminal?

[ruben-arts]

Ah @baszalmstra correctly noted that you are talking about the above mentioned workaround, and not the PR I've been working on. Assuming the conda activation also updates the PROMPT_COMMAND this might indeed break other behavior. I hope the #385 will fix it properly for you.

[twrightsman]

Sorry for the confusion @ruben-arts ! Yes, looking foward to #385 merging

[ruben-arts]

#388

Thanks so much @ruben-arts! v0.6.0 works great
