Python Language Tutorial => Using virtualenv with fish shell

Example

Fish shell is friendlier yet you might face trouble while using with virtualenv or virtualenvwrapper. Alternatively virtualfish exists for the rescue. Just follow the below sequence to start using Fish shell with virtualenv.

Install virtualfish to the global space
```
 sudo pip install virtualfish
```

Load the python module virtualfish during the fish shell startup

 $ echo "eval (python -m virtualfish)" > ~/.config/fish/config.fish

Edit this function fish_prompt by $ funced fish_prompt --editor vim and add the below lines and close the vim editor
```
 if set -q VIRTUAL_ENV
     echo -n -s (set_color -b blue white) "(" (basename "$VIRTUAL_ENV") ")" (set_color normal) " "
 end
```
Note: If you are unfamiliar with vim, simply supply your favorite editor like this $ funced fish_prompt --editor nano or $ funced fish_prompt --editor gedit

Save changes using funcsave
```
 funcsave fish_prompt
```

To create a new virtual environment use vf new

 vf new my_new_env # Make sure $HOME/.virtualenv exists

If you want create a new python3 environment specify it via -p flag
```
 vf new -p python3 my_new_env
```
To switch between virtualenvironments use vf deactivate & vf activate another_env
