commit-msg.sh

#!/usr/bin/env bash

# set this to your active development branch
develop_branch="develop"
current_branch="$(git rev-parse --abbrev-ref HEAD)"

# only check commit messages on main development branch
[ "$current_branch" != "$develop_branch" ] && exit 0

# regex to validate in commit msg
commit_regex='(wap-[0-9]+|merge)'
error_msg="Aborting commit. Your commit message is missing either a JIRA Issue ('WAP-1111') or 'Merge'"

if ! grep -iqE "$commit_regex" "$1"; then
    echo "$error_msg" >&2
    exit 1

Hi,

I wrote a regex for commit message convention 1.0.0 which is based off the Angular Convention.

commit_regex='^(feat|fix|build|chore|docs|style|refactor|perf|test)(\(.+\))?!?: (.+[^.\r\n])([\r\n]+(.+[\r\n]+)+)?$'

This is a simple, lightweight commit message convention enforcing a format like this:

<type>[optional scope]: <description>

[optional body]

[optional footer(s)]

This should work out of box but you can modify it the way you want. Hope it's helpful!

Hi Remirno, you should add the '?' question mark before group 2 because the scope is not a positional argument in the conventional commit,
so it should be like this;
^(feat|fix|build|chore|docs|style|refactor|perf|test)?(\(.+\))?!?: (.+[^.\r\n])([\r\n]+(.+[\r\n]+)+)?$

You'd need to write a server-side commit hook for that
