README

A Composer plugin that allows for regex replacements patches using composer-patches.

Requirements

• PHP 8.0.0 or higher
• cweagans/composer-patches, preferably on commit 5269693119b245e273db052f12ab23d74aca26fc or later.
  • (note: this has to be installed through either dev-main or a custom repositories entry, as this package version isn't tagged on Packagist)

First of all, install the package using composer require lexisother/composer-patches-regex.

You should be prompted to allow the plugin to run code, if not, add the following to your composer.json:

{
  // ...
  "config": {
    "allow-plugins": {
      // ...
      "lexisother/composer-patches-regex": true
    }
  }
}

Defining patches

A patch looks simple. For the most part they are like regular composer-patches entries. You can read more about the general definition of patches here.

It is important to note that this plugin only supports patches defined with the expanded format.

Let's define a simple patch for a package with the following file in its root directory (vendor/scope/packagename):

I am some original text. I love being original.

We want to change the word "some" to "a bit of" and all instances of "original" to "copied". Our patch for this would look as follows:

{
  // ...
  "extra": {
    "patches": {
      "scope/packagename": [
        {
          "description": "A simple description of your patch here",
          "url": "./.gitignore",
          "extra": {
            "regex": {
              "files": {
                "someFile": [
                  {
                    "find": "/some/",
                    "replace": "a bit of"
                  },
                  {
                    "find": "/original/g",
                    "replace": "copied"
                  }
                ]
              }
            }
          }
        }
      ]
    }
  }
}

Note

When using the extra.regex.files key, please set the patch url to some arbitrary local file. composer-patches requires there to be a url, but we don't use it.

After running composer patches-relock and composer patches-repatch, vendor/scope/packagename/someFile would now look like this:

I am a bit of copied text. I love being copied.

Options

The plugin exposes some options to change the behaviour of the patcher. All of these options should be set directly inside extra.regex.

fromUrl

Setting this option to true makes the plugin ignore the files key and instead download the JSON from the specified URL. So if you are migrating your local patches to a file that is hosted remotely, please set your patch's url field to a valid URL pointing to your file.

ignoreErrors

Setting this option to true prevents composer-patches from failing with "No available patcher was able to apply patch" if any of your patches contain errors.
