Not autoactivating virtualenv when using tmux split pane about virtualfish

[ammgws]

Have you tried guarding the call to source asdf in config.fish?

In my case fish is my login shell so guarding it like this would mean it is only sourced once:

if status is-login
    source ~/.asdf/asdf.fish
end

@ammgws I did try adding if status is-login but it is still getting sourced when opening a new split using bind-key - split-window -v -c '#{pane_current_path}'

I think it's because the auto activation feature is relying on a PWD change variable

function __vfsupport_auto_activate --on-variable PWD

and since PWD is not being changed when opening a tmux split pane with the current path, it doesn't trigger the auto activation

My current workaround is

# config.fish
# Load asdf-vm
if status is-login
    source ~/.asdf/asdf.fish
    emit asdf_loaded
end

Then I modified my auto_activation.fish

function __vfsupport_auto_activate --on-event asdf_loaded --on-variable PWD
    ....
    some code here
    ....
    if test $new_virtualenv_name != ""
        # if the virtualenv in the file is different, switch to it
        # if begin; not set -q VIRTUAL_ENV; or test $new_virtualenv_name != (basename $VIRTUAL_ENV); end
        if begin; or test $new_virtualenv_name != (basename $VIRTUAL_ENV); end
            vf activate $new_virtualenv_name
            set -g VF_AUTO_ACTIVATED $activation_root
        end

For some reason, things started working again. I'm not sure how and why..
