Git commit-msg hook to validate message format.

	#!/usr/bin/env bash
	set -euo pipefail

	# ====================================================================================================
	# The script below allows to check automatically a commit message before saving it.
	# In order to use it, you have to copy this code in .git/hooks/commit-msg inside your project.
	# Don't forget to add proper permissions if you create a new file (chmod +x). Bash 3+ is required.
	# ====================================================================================================

	COMMIT_MSG=$(cat $1)

Update a JavaScript function body without overwriting the whole code.

	/*
	In the code below, "form_validation" is a JavaScript function provided by a third-party component. This function validates
	and then sends the form values. Since these two behaviors are linked, it's impossible to only validate the form in this state.
	But we can update the function without overwriting the whole code.
	*/

	if (typeof form_validation === 'function') {
	var definition = form_validation.toString()
	.replace(/myForm\.submit;?/, 'return true;');

ajardin / git-contributions.bash

Last active November 9, 2021 16:10

A bash script that generates a report about contributions to a Git repository.

	#!/bin/bash

	# ====================================================================================================
	# The script below allows to have a quick overview of contributions on a Git repository. Bash 4+ is required.
	# Especially useful when we do not have access to graphs like those that we can find on Github.
	#
	# This script handles three non-mandatory parameters:
	# - START is used to keep commits only since the given date (default = 01 Jan 2000).
	# - END is used to keep commits only until the given date (default = 01 Jan 2050).
	# - MINIMUM is used to define the minimum number of commits in order to appear in the report (default = 10).
