setv: Lightweight Python virtual environment manager

Update[March 30, 2016]: I created setV as a separate project with installer and readme. This post is quite old.

I like to have a separate virtualenv for each python project. This ends up having virtual-environments for each project that I often find difficult to manage. All my virtual-environments resides in ~/virtualenvs directory but to activate/deactivate a virtual environment every time is a tedious job.

An easy solution to this is to install virtualenvwrapper, but then I have run commands like workon & mkvirtualenv. I don’t want to do that. Can I manage virtual environment using single command?. Luckily I have Bash function I find very handy. It lists all available virtual environments and can switch the environment as needed.

Usage:

List all virtual environment
```
  setv [TAB] [TAB]

or

  setv -l
```

Switch virtual environment

  setv <VIRTUAL-ENVIRONMENT-NAME>

for example:

  setv rango

Create new virtual environment

  setv -n <NEW-VIRTUAL-ENVIRONMENT-NAME>

for example:

  setv -n foobar

Delete existing virtual environment

  setv -d <EXISTING-VIRTUAL-ENVIRONMENT-NAME>

for example:

  setv -d foobar

Deactivate virtual environment
```
  deactivate
```

Download

The script is available here and can be downloaded via wget

wget https://raw.github.com/psachin/bash_scripts/master/virtual.sh

Install

Set VIRTUAL_DIR_PATH value to your virtual environments directory-path in virtual.sh file. By default it is set to ~/virtualenvs/
Create a directory to hold all virtual environments
```
  mkdir ~/virtualenvs
```
Added this line to your .bashrc or any local rc script.
```
  source /path/to/virtual.sh
```
