Python virtualenv wrapper script

.bashrc

Add into your .bashrc on macOS the following alias:

alias workon='source ~/bin/workon.sh'

I believe on Linux the alias should look like:

alias workon='~/bin/workon.sh'

workon.sh

#!/bin/sh
#
# Workon virtualenv wrapper
#
VENVDIR=~/Pyenv
ENV=$1
DIR=`find $VENVDIR -maxdepth 1 -type d -iname $ENV -print -quit`

if [[ ! -z "${DIR}" ]]; then
    echo "Activating virtualenv $ENV"
    if [[ ! -z "$VIRTUAL_ENV" ]]; then
        echo "Deactivating old virtualenv"
        deactivate
    fi
    source $DIR/bin/activate
else
    echo "Cannot find virtualenv!"
    echo "Valid virtualenvs:"
    find $VENVDIR -maxdepth 1 -type d -execdir echo "  {}" \;
fi
