minimum-envwrapper

Minimum virtual environment management, in portable POSIX Shell.

Commands

• mkvirtualenv VENV - Create a new virtual environment
• workon VENV - Activate a virtual environment
• lsvirtualenv - List all virtual environments
• rmvirtualenv VENV - Delete a virtual environment

Environment Variables

• WORKON_HOME - If defined, virtual environments will be placed in this directory. Otherwise, virtual environments will be created in $HOME/.virtualenvs/

Example Usage

$ . ./minimum-envwrapper.sh   # (But really, put this in your shell rc.)
$ lsvirtualenv
$ mkvirtualenv new-venv
$ lsvirtualenv
new-venv
$ workon new-venv
$ which python
/home/user/.virtualenvs/new-venv/bin/python
$ rmvirtualenv new-venv
$ lsvirtualenv
$

Requirements

• A POSIX compliant shell (BASH, ZSH, KSH, DASH, etc)
• The venv module, from the python3 standard library

Motivation

1. This prevents me from needing to set up a virtual environment, so that I can manage my virtual environments.
2. python2 is finally dead, so this can rely on the python3 venv module.
3. I only used these 4 commands anyway.
4. The alternatives were not compatible with ksh.
