Automatically activate conda environments

.condaauto.sh

#!/bin/bash

# .condaauto.sh automatically activates a conda environment when enterring
# a folder that contains a .condaauto file. The first line in the .condaauto
# file is the name of the conda environment.
#
# To make this work you have to source .condaauto.sh in your bashrc or
# equivalent.
#
# I feel sorry for my bash foo :(

function _conda_auto_activate() {
  if [ -e ".condaauto" ]; then
    # echo ".condaauto file found"
    ENV=$(head -n 1 .condaauto)

    # Check to see if already activated to avoid redundant activating
    if [[ $PATH == *"$ENV"* ]]; then
      echo "Conda env '$ENV' already activated."
    else
      source activate $ENV
    fi
  fi
}

function chpwd() {
  _conda_auto_activate
}

Just started using conda and wanted similar functionality to other version management tools when traversing directories. This is awesome. Thank you!
