commit-msg

#!/bin/sh

commit_regex='(([[:upper:]]*\-[0-9]*)|fixup!)'
error_msg="Aborting commit. Your commit message is missing a JIRA ticket"


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

if ! grep -iqE "$commit_matches_branch_regex" "$1";
then
    echo "your JIRA ticket number doesn't match the branch name" >&2
    exit 1

pre-commit

#!/bin/bash
# Stops accidental commits to master and develop. https://gist.github.com/stefansundin/9059706

BRANCH=`git rev-parse --abbrev-ref HEAD`

if [[ "$BRANCH" == "master" || "$BRANCH" == "develop" ]]; then
	echo "You are on branch $BRANCH. Are you sure you want to commit to this branch?"
	echo "If so, commit with -n to bypass this pre-commit hook."
	exit 1
fi

exit 0

pre-rebase

#!/bin/sh
#
# The "pre-rebase" hook is run just before "git rebase" starts doing
# its job, and can prevent the command from running by exiting with
# non-zero status.
#
# The hook is called with the following parameters:
#
# $1 -- the upstream the series was forked from.
# $2 -- the branch being rebased (or empty when rebasing the current branch).
#

# fix the brain dead behaviour of visual studio when reloading modified projects

find  -type f  -name "*.sln" -exec touch {} +

prepare-commit-msg

#!/bin/bash
# Adds JIRA Ticket number to commit messages
# Based on http://waiting-for-dev.github.io/blog/2014/07/19/append-issue-number-to-commit-message-automatically-with-git-hooks/

if ! [  -z ${2+x} ]; then
   COMMIT_PREFIX=$(git rev-parse --abbrev-ref HEAD | grep -o '[[:upper:]]*\-[0-9]*' | head -1)
   sed -i '' "1s/^/[$COMMIT_PREFIX] /" "$1"
