Useful unreal engine git hooks

delete_bin_folders.py

import os, shutil
from subprocess import check_output

bin_path = "Binaries"
print(bin_path + " folder is going to be deleted if it exists")
shutil.rmtree(bin_path, ignore_errors=True)
    
int_path = "Intermediate"
print(int_path + " folder is going to be deleted if it exists")
shutil.rmtree(int_path, ignore_errors=True)

post-checkout

#!/bin/sh
command -v git-lfs >/dev/null 2>&1 || { echo >&2 "\nThis repository is configured for Git LFS but 'git-lfs' was not found on your path. If you no longer wish to use Git LFS, remove this hook by deleting .git/hooks/post-checkout.\n"; exit 2; }
git lfs post-checkout "$@"

git diff HEAD --quiet $1 -- Source

if [[ $? = 1 ]]
then
	echo "Differences detected between previous and current branch Source's folder"
	py .git/hooks/delete_bin_folders.py "$@"
else
	echo "No difference in source folder between previous and current branch"
fi

post-merge

#!/bin/sh
command -v git-lfs >/dev/null 2>&1 || { echo >&2 "\nThis repository is configured for Git LFS but 'git-lfs' was not found on your path. If you no longer wish to use Git LFS, remove this hook by deleting .git/hooks/post-merge.\n"; exit 2; }
git lfs post-merge "$@"

git diff HEAD@{1} --quiet HEAD -- Source

if [[ $? = 1 ]]
then
	echo "Pull/Merge detected changes in the source folder"
	py .git/hooks/delete_bin_folders.py "$@"
else
	echo "No changes detected during Pull/Merge in the source folder"
fi

You can get rid of line 2 and 3 of post-merge and post-checkout if you don't use lfs (working on Unreal, I think you should though!)

In order for this to work, on your repo, just drag and drop those files inside your .git/hooks folder.
If a post-merge and a post-checkout exists already, you'll have to manually add the lines that intereset you for it to work (which should at least be everything after line 4)

You need to have python installed on your system for it to work.

You need to do that on every computer locally.

This is a great starting point, thanks!
