To run a Python package on a pre-commit git hook, you can follow these steps:

  1. Create a virtual environment (optional): It's recommended to work within a virtual environment to ensure that the dependencies are isolated. You can create a virtual environment using python -m venv myenv and activate it using source myenv/bin/activate (for Linux/Mac) or .myenvScriptsactivate (for Windows).
  2. Install the required packages: Install the necessary packages in your virtual environment using pip install mypackage (replace mypackage with the name of your Python package and any other dependencies).
  3. Create a pre-commit hook script: In your git repository, create a file named .git/hooks/pre-commit if it doesn't exist already. This file is the script that will run before each commit.
  4. Add executable permissions: Make the script executable by running chmod +x .git/hooks/pre-commit in your git repository.
  5. Edit the hook script: Open the pre-commit file in a text editor and add the following code:
1
2
3
4
5
6
7
8
#!/bin/bash

# Activate the virtual environment (if applicable)
source path/to/virtual/env/bin/activate

# Run your Python package or command
python -m mypackage.some_module
# Replace 'mypackage.some_module' with the appropriate command or entry point for running your package.


Make sure to replace path/to/virtual/env with the actual path to your virtual environment directory (if you're using one).

  1. Save and exit the script.


Now, whenever you run git commit, the pre-commit hook script will be executed, activating the virtual environment (if applicable) and running your Python package or command. If there are any issues or errors during the execution, the commit will be aborted.


Note: Ensure that the virtual environment and dependencies are properly set up and installed. If you need to update or install additional packages before running your package, you can add those pip install commands within the pre-commit hook script.


Remember to test your pre-commit script thoroughly before using it in a production environment.
