Auto activate and deactivate python venv using zsh

When I found out about python venv (apt-get install python3-venv) I became an instant addict. It's clean, it's built-in and it's explicit.

Now every time I create a new project folder I automatically run python3 -mvenv venv && source ./venv/bin/activate.

But typing ./venv/bin/activate and then deactivate is too much work for my lazy programmer head.

So I decided to finally invest 10 minutes to free me from activating and deactivating python's env every time I enter or leave a folder with my standard ./venv folder:

#---------------------------------------------- chpwd pyvenv ---
python_venv() {
  MYVENV=./venv
  # when you cd into a folder that contains $MYVENV
  [[ -d $MYVENV ]] && source $MYVENV/bin/activate
  # when you cd into a folder that doesn't
  [[ ! -d $MYVENV ]] && deactivate > /dev/null 2>&1
}
autoload -U add-zsh-hook
add-zsh-hook chpwd python_venv

python_venv

Enter fullscreen mode

Exit fullscreen mode

edit: just figured out that deactivating was working because of other stuff installed in my shell. Now it's a bit more agressive but works 100%
