Run in existing shell OR create interactive child shell about just

[laniakea64]

If there were a way to tell Just to execute the command in the existing shell, this would operate the same as a normal alias, which is the ideal.

This is not possible, the closest you can get would be something like #1957 (comment)

If that is not possible, it would be nice if the new shell instance used to run the command could be made into an interactive child shell instance, which would achieve nearly the same effect.

Do any of the ideas in https://unix.stackexchange.com/questions/123103/how-to-keep-bash-running-after-command-execution work for your case?

It looks like the follow works:

activate:
  bash -i <<< 'source venv/bin/activate; exec </dev/tty'

However, I can only get it to work for bash, not zsh. If there's ever a way to build the functionality in, that would be ideal. But for now this is a good enough workaround.

This is a longstanding request, and unfortunately, I don't think there's a good way to support this, since doing so would probably require different commands for each shell, and just tries to be shell-agnostic.

@fastfedora thanks for this, found a way to get this to work in zsh:

activate-venv:
  zsh -is <<< 'source .venv/bin/activate; exec </dev/tty'

I also found this oh-my-zsh plugin: https://github.com/ohmyzsh/ohmyzsh/tree/master/plugins/python#virtual-environments

Thanks so much. That works for me too.

I'll check this out. Thanks!
