virtualenv-fish

Fast and simple virtualenv utilities for the Fish shell.

Installation

This package can be installed with fisher, fundle or oh-my-fish:

fisher add orf/virtualenv-fish

fundle plugin 'orf/virtualenv-fish'

omf install virtualenv-fish

Usage

Temporary virtual environment: tmpenv

Running tmpenv will create a temporary virtual environment for you to experiment with.

You can add custom package that will always be installed by creating a file in ~/.config/virtualenv-fish/global_requirements.txt. e.g:

ipython
numpy

Why not virtualfish?

Virtualfish is pretty complete and contains a lot of functionality. However I found that it was slowing my shell startup down a lot. The main offender is the compulsory eval (python -m virtualfish) command you add to your config.fish. This easily adds 400 to 500ms to every shell startup.

The most used feature for me was the temporary virtual environment management, so I've ported this to pure fish.
