Starpatch

Simple file patcher made in Zig using raylib

It is the last tool from a set created for ROM hacking (any file in reality). The other two are:

• Stardust: a simple hexadecimal editor with extra features like symbols' table and relative search
• Startile: a simple tile editor

Raylib was not entirely needed in this project, but I wanted to use its helper functionalities

All these projects were developed to better learn Zig and raylib, while fulfilling some nostalgia from the early 2000's

Building

Simply clone/download this repository and run:

$ zig build

Using

Create a patch

To create a patch file, run:

$ Starpatch create <original file> <patched file> <patch file>

It will create the patch file with all patches needed to make original file become the patched file. This file can later be applied with the other commands

Patch a file

To patch a file, run:

$ Starpatch patch <original file> <patch file> <patched file>

It will create the patched file with all patches contained in patch file applied to the original file

Unpatch a file

To unpatch a file, run:

$ Starpatch unpatch <patched file> <patch file> <original file>

It will create the original file with all patches contained in patch file unapplied to the patched file

Examples

You can check the run.bat, resources/bigger.txt and resources/smaller.txt to see how it works and in action
