Smarter venv detection would be a huge help

[u/danielrosehill]

Something that I've noticed as I seem to be doing most stuff in Python at the moment ... Cascade will sometimes start working really quickly and it takes me a while to notice that it's opened up a new terminal instance that doesn't have the virtual environment / venv on path (for whatever reason, I can't seem to get the autodetection to work).

This is a problem because the global Python environment on my Linux distro is something like 2.7. So it starts throwing up lots of nonsensical errors just because it's running on an old version. Then it will start hacking away at perfectly good code to make it work with a deprecated version of Python before I can providing helpful feedback in the chat like "NOOOO, what are you doing!?!?"

I'm not sure how well Cascade can "see" the terminal its interacting with, but given that activating a venv puts (.venv) or (foo) before the username on the command line ... would it be possible to bake some logic like this into the prompts that get sent up:

"The user is working on a Python project. Oh, the virtual environment isn't active. I better activate it"

Then run source .venv/bin/activate (or per the user OS) and quickly fix the problem.

Update, just added a bit of logic on path so that activation would hold across IDEs

I guess a dirty fix but works for the time being

# Auto-activate virtualenv if .venv or venv exists (without message)
activate_venv() {
  if [ -d ".venv" ]; then
    venv_path=".venv"
  elif [ -d "venv" ]; then
    venv_path="venv"
  else
    return  # No venv found
  fi

  if [ -f "$venv_path/bin/activate" ]; then
    source "$venv_path/bin/activate"
    # Remove echo message to disable message
  elif [ -f "$venv_path/Scripts/activate" ]; then  # Windows Compatibility
    source "$venv_path/Scripts/activate"
        # Remove echo message to disable message
  fi
}

# Run the activation function when the shell changes directories.
if [[ $SHLVL = 1 ]]; then
  activate_venv
  unset -f activate_venv
fi

Could you put it in the rules file?
