Activation/Deactivation of python virtualenv upon entering a directory

It's not a new or original idea – I've heard about it from Dmitry Gladkov but as usual didn't remember details. So, I've created my own implementation of activation/deactivation of python virtualenv:

#!/bin/bash

PREVPWD=`pwd`
PREVENV_PATH=
PREV_PS1=
PREV_PATH=

handle_virtualenv(){
  if [ "$PWD" != "$PREVPWD" ]; then
    PREVPWD="$PWD";
    if [ -n "$PREVENV_PATH" ]; then
      if [ "`echo "$PWD" | grep -c $PREVENV_PATH`" = "0"  ]; then
         source $PREVENV_PATH/.venv
         echo "> Virtualenv `basename $VIRTUALENV_PATH` deactivated"
         PS1=$PREV_PS1
         PATH=$PREV_PATH
         PREVENV_PATH=
      fi
    fi
    # activate virtualenv dynamically
    if [ -e "$PWD/.venv" ] && [ "$PWD" != "$PREVENV_PATH" ]; then
      PREV_PS1="$PS1"
      PREV_PATH="$PATH"
      PREVENV_PATH="$PWD"
      source $PWD/.venv
      source $VIRTUALENV_PATH/bin/activate
      echo "> Virtualenv `basename $VIRTUALENV_PATH` activated"
    fi
  fi
}

export PROMPT_COMMAND=handle_virtualenv

Just paste this code into your

$HOME/.bash_profile

and place

.venv

file with declaration like below:

VIRTUALENV_PATH=$HOME/.envs/sampleenvironment

And it should works like a charm. Script only for bash!
