envs

This is my git-friendly manager for handling Python virtual environments. It lets you easily create, activate, and update your environments. It keeps track of package dependencies with venv-freeze using $VENV_DIR/<env_name>/requirements.txt.

Examples

Creating a new environment: venv-create newenv
Activating an environment: venv-activate myenv
Freezing an environment's requirements: venv-freeze myenv
Initializing all environments on another system: venv-init

Setup

Fork the repository by visiting: https://github.com/skelouse/envs/fork
Clone your forked repository. This command will clone the repository into the default directory: $HOME/envs

git clone git@github.com:<your_username>/envs.git $HOME/envs

Add this line to your shell configuration file (.bashrc, .zshrc, etc.):

source "$HOME/envs/venv.sh"

Scripts

venv.sh

This script provides several functions to manage python virtual environments:

venv-activate <env_name>: Activates the specified virtual environment.
venv-freeze [env_name]: Freezes the current environment's packages into a requirements.txt file. If no environment is specified, it uses the currently active one.
venv-create <env_name>: Creates a new virtual environment with the specified name.
venv-init: After a clone will iterate environments $VENV_DIR/<env_name/requirements.txt and install the dependencies for those environments

After venv-freeze, track the changes with Git:

cd "$VENV_DIR/<env_name>"
git add requirements.txt
git commit -m "Update dependencies for <env_name>"
git push origin master

Environment Variables

These scripts use the following environment variables, which you can customize:
