# Git hooks for Pandemonium Engine
This folder contains Git hooks meant to be installed locally by Pandemonium Engine
contributors to make sure they comply with our requirements.
## List of hooks
- Pre-commit hook for `clang-format`: Applies `clang-format` to the staged
files before accepting a commit; blocks the commit and generates a patch if
the style is not respected.
You may need to edit the file if your `clang-format` binary is not in the
`PATH`, or if you want to enable colored output with `pygmentize`.
- Pre-commit hook for `black`: Applies `black` to the staged Python files
before accepting a commit.
- Pre-commit hook for `make_rst`: Checks the class reference syntax using
`make_rst.py`.
## Installation
Copy all the files from this folder into your `.git/hooks` folder, and make
sure the hooks and helper scripts are executable.
#### Linux/MacOS
The hooks rely on bash scripts and tools which should be in the system `PATH`,
so they should work out of the box on Linux/macOS.
#### Windows
##### clang-format
- Download LLVM for Windows (version 8 or later) from
<https://releases.llvm.org/download.html>
- Make sure LLVM is added to the `PATH` during installation
##### black
- Python installation: make sure Python is added to the `PATH`
- Install `black` - in any console: `pip3 install black`
## Custom hooks
The pre-commit hook will run any other script in `.git/hooks` whose filename
matches `pre-commit-custom-*`, after the Godot ones.
