One can use MD5 or plain text diff to see differences in PDF files. If that's not enough, here's how to use diffpdf which knows how to diff based on appearance or words:

brew install diff-pdf
edit your ~/.gitconfig to add this:

[difftool "diffpdf"]
  cmd = diff-pdf --view \"$LOCAL\" \"$REMOTE\"

Git tricks

A place to store git tricks I use (and still forget sometimes).

Access branches using working trees

Sometimes it's usefull to access multiple branches of a git repository at the same time, e.g to compare different versions of CAD designs or to allow copying parts from one brach to the other. One way to do this is cloning the repository multiple times, but this typicaly takes a while. For copying things from text files like code a web based repository browser like gitweb or Github works fine, but this isn't always availible.

A more efficient method is using [git's work-tree command][git-worktree]. This allows to check out multiple versions of the same repository, using the same gitdir as the original repo, saving time and space. To do this:

	"""
	Exports Issues from a specified repository to a CSV file

	Uses basic authentication (Github username + password) to retrieve Issues
	from a repository that username has access to. Supports Github API v3.
	"""
	import csv
	import requests

	#!/bin/sh

	# Git pre-push script to notify the user in case more than 1 commit is pushed.
	# Handy when pushing to the gerrit review system where each commit will result
	# in a change review. Pushing to or from an incorrect branch could result in a
	# bunch of unintended change reviews to be created and/or changes dependent on
	# unsubmitted changes.

	remote="$1"
	url="$2"

	Set variables
	=============

	Set a variable in different environments. Example sets `$VAR` to "fubar".

	## Linux, MacOS, ...
	```
	VAR=fubar
	```

	:: Parses a .env file with windows cmd similar to Posix source
	:: Note: This only works for oneliners when delayed varaible extension is used
	:: e.g with cmd /V:ON
	:: Pass the /F flag to overwrite existing variables
	@echo off

	setlocal enabledelayedexpansion

	set envfile=.env
	set force=0
