Fish shell tooling to automagically activate and deactivate Python's virtualenv when moving between directories.
⚠️ This is a Fish shell script, it will not work on Bash or Zsh.
For example, let's say you have a project in ~/my-project with a virtualenv inside:
~ $ # note that no virtualenv is active
~ $ cd ~/my-project
(.venv) my-project $ # note that the virtualenv was activated
(.venv) my-project $ cd ~
~ $ # now the virtualenv is deactivatedBy default it will look for .venv or venv. But you can replace that with DIRVENV_DIRS environment variable. For example, if you want it to look for virtualenv called forty or two:
set -x DIRVENV_DIRS forty,twoIf you manually activates a virtualenv, dirvenv will not deactivate it.
For example, if you have ~/my-project/.venv and you cd ~/my-project/tests, it will activate the virtualenv in the parent directory (recursively).
If you have more than one shell, dirvenv from one shell will not mess up with the magic in the other shells.
If you want dirvenv to ignore any directory, just use DIRVENV_IGNORE with full paths to the directories. For example:
set -x DIRVENV_IGNORE /not/my/monkeys,/not/my/circusFrom now on, dirvenv will ignore any action in both these directories and their sub-directories.
Probably it works with Fisher, but I haven't tested it myself:
$ fisher install cuducos/dirvenv.fishAlternatively you can use the install.fish script:
$ curl https://raw.githubusercontent.com/cuducos/dirvenv.fish/refs/heads/main/install.fish | sourceThere is an uninstall.fish script for that:
$ curl -LO https://raw.githubusercontent.com/cuducos/dirvenv.fish/refs/heads/main/uninstall.fish
$ source uninstall.fish
$ rm uninstall.fishThank you, direnv! The similarity in the name is intentional, the user experience of direnv is so great I wanted to offer the same seamless smooth experience with dirvenv : )
