Python MacOS - switch between your Virtual (pipenv) Environments

[Dirk-Jan Uittenbogaard]

Team,

As I'm using a lot of virtual environments with PIPENV, it became harder to keep track of the environments that I have setup. And that was the reason to create this script which:

1. List all of your (pipenv) virtual environments
2. Select one
3. Change to the actual folder

Requirements

• MacOS
• use of Pipenv (instead of the default virtualenv)

Script:

#!/bin/zsh
my_env_folder="$HOME/.local/share/virtualenvs"

#__Steps are documented in the 'echo' commands below
clear
echo "__1__LIST env folders with a number, user enters env number"
ls $my_env_folder | cat -n
read a

clear
echo "\n__2__SET the selected FOLDER name"
my_env_selected=`ls $my_env_folder | head -n $a | tail -n 1`
my_env_selected=$my_env_folder/$my_env_selected
echo "     $my_env_selected\n"

echo "__3__CHANGE to the ACTUAL env folder name found in the envs '.project' file\n"
real_folder=`cat $my_env_selected/.project`
DIR=$( cd "${real_folder}" && pwd )
cd "${DIR}"
echo "__4__DONE!\n     CURRENT FOLDER: $PWD\n     NEXT: activate your virtual environment\n\n"
# IF all fails, the following line copies "cd folder_name" 
# Next, press CMD-V and then ENTER. 
echo "cd $real_folder" | pbcopy

When you run the script it will list your virtual environments and ask you to enter the number of the virtual environment you want to use. Then it will read the actual folder name of that environment in the .storage file and change to that folder.

Enjoy!

Does the code not change to the right folder?

You could add the following lines to copy the destination foldername. So you only have to paste + press enter.

# IF all fails, the following line copies "cd folder_name" 
# Next, press CMD-V and then ENTER. 
echo "cd $real_folder" | pbcopy

Dirk,

I tried it out but as soon as the script exits, I am still in the same directory where I executes the script.

__2__SET the selected FOLDER name
/Users/davidn/.local/share/virtualenvs/backend-mIHxTv_C

__3__CHANGE to the ACTUAL env folder name found in the envs '.project' file

__4__DONE!
CURRENT FOLDER: /Users/davidn/Desktop/workspace/CLUS_Demo/backend
NEXT: activate your virtual environment

Hello @davidn# ,

Ah, that was one of my biggest challenges: change to a folder from a script. A script executes in a new shell and when it finished, you exit that shell and therefore go back to where you were before  

The method that I used works perfeclty on my Mac (MacOS 12.3.1) with my settings. 

Alternatively, at the end of the script your could add the following lines: 

# IF all fails, the following line copies "cd folder_name" 
# Next, press CMD-V and then ENTER. 
echo "cd $real_folder" | pbcopy

This copies the full path to your copy/paste buffer. As a result the only thing you have to do after running the script is paste + enter.

I will continue to look for alternative ways.
