Activate python virtual environment in pane

[ParkerKain]

Hey! Loving zellij so far!

For python development, I very regularly want to create a new pane, and then source some virtual environment via source .venv/bin/activate, which attaches me to a virtual environment for running other commands via the shell. I want to do this for all of my zellij panes, for running tests, opening my editor, etc.

However, it looks like if I configure a layout via command to run the source command, I don't get spit back out into my shell, I am in the "command mode" - and if I exit it, I am not attached to my virtual environment.

Is there a standard way of doing this I am missing? Thanks!

Run into the same problem. I suppose that is because source is a Bash builtin and as Zellij doc states:

command is a string (path) to an executable that should be run in this pane instead of the default shell.

I've also tried the following:
bash --rcfile <(cat ~/.bashrc; echo 'source venv/bin/activate';)
Here Bash <(command_list) syntax (called Process Substitution) creates temp file and redirects process output to it.
That works fine in bash shell, but not when I`m trying to use it in predifined Zellij layout:

layout {
    pane command="bash" {
        args "--rcfile" "<(cat ~/.bashrc; echo 'source venv/bin/activate';)"
    }
}

@ParkerKain Found a way to source virtualenv like this:

layout {
    pane command="bash" {
        args "-c" "bash --rcfile <(cat ~/.bashrc; echo 'source venv/bin/activate';)"
    }
}
