auto-installed git hooks for new repos with git templates

git_hooks_with_git_templates.md

Here is how you can have some default git hooks auto installed with every new repo you clone. I use this to install a pre-push hook that adds a confirmation step to any push to main so that I don't accidentally push up any changes.

1. set up git to use a templatedir

git config --global init.templatedir '~/.git_template'
mkdir -p ~/.git_template/hooks

2. add in the pre-push hook code in .git_template/hooks/pre-push

#!/bin/bash

protected_branch='main'
current_branch=$(git symbolic-ref HEAD | sed -e 's,.*/\(.*\),\1,')

if [ $protected_branch = $current_branch ]
then
    read -p "You're about to push main, is that what you intended? [y|n] " -n 1 -r < /dev/tty
    echo
    if echo $REPLY | grep -E '^[Yy]$' > /dev/null
    then
        exit 0 # push will execute
    fi
    exit 1 # push will not execute
else
    exit 0 # push will execute
fi

3. make sure the new hook is marked as executable by running chmod +x pre-push on command line

4. profit.
