How can I run a virtualenv python script as a git pre-commit hook

Question

This is my pre-commit script:

#!/bin/bash
for f in .git/hooks/pre-commit.d/*; do
    if [ -x \"$f\" ]; then
        if ! \"$f\"; then
            echo \"DID          


        

Answer 1

What I ended up doing is: the .git file structure:

• .git/hooks/pre-commit
• .git/hooks/pre-commit-main.py

.git/hooks/pre-commit:

#!/usr/bin/env bash
export PATH="$THE_GOOD_PATH"
python "$GIT_DIR/hooks/pre-commit-main.py"

.git/hooks/pre-commit-main.py:

#!/usr/bin/env python
import sys
print sys.version_info

Then, when you call git commit, make sure that THE_GOOD_PATH, is defined:

export THE_GOOD_PATH="$PATH"
git commit

You could also export THE_GOOD_PATH="$PATH" from your .profile or the toplevel of your application and symlink all hooks to a single file.

This method has the advantage of being virtualenv agnostic: it also works with Ruby RVM rbenv.

I wrote to the Git developers at: http://permalink.gmane.org/gmane.comp.version-control.git/258454 asking them to leave our PATH alone, but the initial reply was WONTFIX.

You can check in your pre-commit script for the $VIRTUAL_ENV variable and prepend it to $PATH accordingly:

#!/bin/bash

if [ -n $VIRTUAL_ENV ]; then
    PATH=$VIRTUAL_ENV/bin:$PATH
fi

for f in .git/hooks/pre-commit.d/*; do
    if [ -x "$f" ]; then
        if ! "$f"; then
            echo "DID NOT COMMIT YOUR CHANGES!";
            exit 1
        fi
    fi
done
