Patch Splitter for Magento 2

This script splits a patch file into multiple patch files based on the modules that the patch is changing. It detects the module that is being changed and creates a different patch file for each module. The script also helps the user to configure PHP Composer to use the new patch that works with Composer.

Usage

1. Run the script from the root of your Magento project.
2. Provide the patch file as an argument, e.g. ./script.sh your_patch_file.patch.
3. The script will create a new directory called .composer_patches (or composer_patches or patches if one of these directories already exists) and split the patch file into multiple files, each corresponding to a different module.
4. The script will also output a JSON object that can be used to configure PHP Composer to use the new patch files.

Requirements

• The script must be run from the root of a Magento project.
• The composer.json file must exist in the current directory.

Notes

• If the patch file only affects one module, the script will output a message indicating that the patch file only works with one module and exit.
• If the composer.json file contains the string "magento-cloud", the script will output a message indicating that the patch file should be placed in the m2-hotfixes directory and exit.
