Fish shell with python virtual environements

[andreichalapco]

Hi.

I've stumbled across the following problem. How can I configure my fish shell to show me in parantheses (like in the bash shell) the python virtual environment I'm currently using ... ?

Python's activate.fish script does this by default, unless you have set $VIRTUAL_ENV_DISABLE_PROMPT.

So either you are using some other method to activate your virtual environment, or the prompt you are using disables it, presumably to show it elsewhere. E.g. our "disco" sample disables it to display the venv itself on the right side:

fish-shell/share/tools/web_config/sample_prompts/disco.fish

Lines 84 to 90 in 70d2e97

	set -q VIRTUAL_ENV_DISABLE_PROMPT
	or set -g VIRTUAL_ENV_DISABLE_PROMPT true
	set -q VIRTUAL_ENV
	and set -l venv (string replace -r '.*/' '' -- "$VIRTUAL_ENV")
	set_color normal
	string join " " -- $venv $duration $vcs $d

Thx for the reply. I use direnv to load my python virtual environment ...

In that case, I'd see what direnv does to do that. I'd assume it doesn't run the activate.fish script in the current shell, so you would have to add the prompt part yourself.

See if $VIRTUAL_ENV is set to the correct value and then add it to your fish_prompt. Something like

if test -n "$VIRTUAL_ENV"
    echo -n (set_color blue)"($VIRTUAL_ENV)"(set_color normal)
end
