Semantic Commit Messages

See how a minor change to your commit message style can make you a better programmer.

Format: <type>(<scope>): <subject>

<scope> is optional

Example

#!/usr/bin/env bash
# fork from https://gist.github.com/jakemhiller/d342ad51505addf78ec628a16fd3280f

changed_files="$(git diff-tree -r --name-only --no-commit-id $1 $2)"

check_run() {
	echo "$changed_files" | grep --quiet "$1" && eval "$2"
}

check_run package.json "npm prune && npm install"

You don't have to delete your local branch.

Simply delete your remote tracking branch:

git branch -d -r origin/<remote branch name> (This will not delete the branch on the remote repo!)

See "Having a hard time understanding git-fetch"

there's no such concept of local tracking branches, only remote tracking branches.
