 [![Basic validation](https://github.com/actions/labeler/actions/workflows/basic-validation.yml/badge.svg?branch=main)](https://github.com/actions/labeler/actions/workflows/basic-validation.yml)

-Automatically label new pull requests based on the paths of files being changed.
+Automatically label new pull requests based on the paths of files being changed or the branch name.
+
+## Breaking changes in V5
+1) The ability to apply labels based on the names of base and/or head branches was added ([#186](https://github.com/actions/labeler/issues/186) and [#54](https://github.com/actions/labeler/issues/54)). The match object for changed files was expanded with new combinations in order to make it more intuitive and flexible ([#423](https://github.com/actions/labeler/issues/423) and [#101](https://github.com/actions/labeler/issues/101)). As a result, the configuration file structure was significantly redesigned and is not compatible with the structure of the previous version. Please read the documentation below to find out how to adapt your configuration files for use with the new action version.
+
+2) The bug related to the `sync-labels` input was fixed ([#112](https://github.com/actions/labeler/issues/112)). Now the input value is read correctly.
+
+3) By default, `dot` input is set to `true`. Now, paths starting with a dot (e.g. `.github`) are matched by default.
+
+4) Version 5 of this action updated the [runtime to Node.js 20](https://docs.github.com/en/actions/creating-actions/metadata-syntax-for-github-actions#runs-for-javascript-actions). All scripts are now run with Node.js 20 instead of Node.js 16 and are affected by any breaking changes between Node.js 16 and 20.

 ## Usage

 ### Create `.github/labeler.yml`

-Create a `.github/labeler.yml` file with a list of labels and [minimatch](https://github.com/isaacs/minimatch) globs to match to apply the label.
+Create a `.github/labeler.yml` file with a list of labels and config options to match and apply the label.

-The key is the name of the label in your repository that you want to add (e.g. `merge conflict`, `needs-updating`) and the value is the path (glob) of the changed files (e.g. `src/**`, `tests/*.spec.js`) or a match object.
+The key is the name of the label in your repository that you want to add (eg: "merge conflict", "needs-updating") and the value is a match object.

 #### Match Object

-For more control over matching, you can provide a match object instead of a simple path glob. The match object is defined as:
+The match object allows control over the matching options. You can specify the label to be applied based on the files that have changed or the name of either the base branch or the head branch. For the changed files options you provide a [path glob](https://github.com/isaacs/minimatch#minimatch), and for the branches you provide a regexp to match against the branch name.

+The base match object is defined as:
 ```yml
- any: ['list', 'of', 'globs']
-  all: ['list', 'of', 'globs']
+- changed-files: 
+  - any-glob-to-any-file: ['list', 'of', 'globs']
+  - any-glob-to-all-files: ['list', 'of', 'globs']
+  - all-globs-to-any-file: ['list', 'of', 'globs']
+  - all-globs-to-all-files: ['list', 'of', 'globs']
+- base-branch: ['list', 'of', 'regexps']
+- head-branch: ['list', 'of', 'regexps']
 ```

-One or both fields can be provided for fine-grained matching. Unlike the top-level list, the list of path globs provided to `any` and `all` must ALL match against a path for the label to be applied.
-
-The fields are defined as follows:
-* `any`: match ALL globs against ANY changed path
-* `all`: match ALL globs against ALL changed paths
-
-A simple path glob is the equivalent to `any: ['glob']`. More specifically, the following two configurations are equivalent:
+There are two top-level keys, `any` and `all`, which both accept the same configuration options:
 ```yml
-label1:
- example1/*
+- any:
+  - changed-files:
+    - any-glob-to-any-file: ['list', 'of', 'globs']
+    - any-glob-to-all-files: ['list', 'of', 'globs']
+    - all-globs-to-any-file: ['list', 'of', 'globs']
+    - all-globs-to-all-files: ['list', 'of', 'globs']
+  - base-branch: ['list', 'of', 'regexps']
+  - head-branch: ['list', 'of', 'regexps']
+- all:
+  - changed-files:
+    - any-glob-to-any-file: ['list', 'of', 'globs']
+    - any-glob-to-all-files: ['list', 'of', 'globs']
+    - all-globs-to-any-file: ['list', 'of', 'globs']
+    - all-globs-to-all-files: ['list', 'of', 'globs']
+  - base-branch: ['list', 'of', 'regexps']
+  - head-branch: ['list', 'of', 'regexps']
+```
+
+From a boolean logic perspective, top-level match objects, and options within `all` are `AND`-ed together and individual match rules within the `any` object are `OR`-ed.
+
+One or all fields can be provided for fine-grained matching.
+The fields are defined as follows:
+- `all`: ALL of the provided options must match for the label to be applied
+- `any`: if ANY of the provided options match then the label will be applied
+  - `base-branch`: match regexps against the base branch name
+  - `head-branch`: match regexps against the head branch name
+  - `changed-files`: match glob patterns against the changed paths
+    - `any-glob-to-any-file`: ANY glob must match against ANY changed file
+    - `any-glob-to-all-files`: ANY glob must match against ALL changed files
+    - `all-globs-to-any-file`: ALL globs must match against ANY changed file
+    - `all-globs-to-all-files`: ALL globs must match against ALL changed files
+
+If a base option is provided without a top-level key, then it will default to `any`. More specifically, the following two configurations are equivalent:
+```yml
+Documentation:
+- changed-files:
+  - any-glob-to-any-file: 'docs/*'
 ```
 and
 ```yml
-label1:
- any: ['example1/*']
+Documentation:
+- any:
+  - changed-files:
+    - any-glob-to-any-file: 'docs/*'
 ```

-From a boolean logic perspective, top-level match objects are `OR`-ed together and individual match rules within an object are `AND`-ed. Combined with `!` negation, you can write complex matching rules.
-
-> ⚠️ This action uses [minimatch](https://www.npmjs.com/package/minimatch) to apply glob patterns.
-> For historical reasons, paths starting with dot (e.g. `.github`) are not matched by default.
-> You need to set `dot: true` to change this behavior.
-> See [Inputs](#inputs) table below for details.
+ If path globs are combined with `!` negation, you can write complex matching rules. See the examples below for more information.

 #### Basic Examples

 ```yml
-# Add 'label1' to any changes within 'example' folder or any subfolders
-label1:
- example/**
+# Add 'root' label to any root file changes
+# Quotation marks are required for the leading asterisk
+root:
+- changed-files:
+  - any-glob-to-any-file: '*'

-# Add 'label2' to any file changes within 'example2' folder
-label2: example2/*
+# Add 'AnyChange' label to any changes within the entire repository
+AnyChange:
+- changed-files:
+  - any-glob-to-any-file: '**'

-# Add label3 to any change to .txt files within the entire repository. Quotation marks are required for the leading asterisk
-label3:
- '**/*.txt'
+# Add 'Documentation' label to any changes within 'docs' folder or any subfolders
+Documentation:
+- changed-files:

 ## Permissions

-In order to add labels to pull requests, the GitHub labeler action requires
-write permissions on the pull-request. However, when the action runs on a pull
-request from a forked repository, GitHub only grants read access tokens for
-`pull_request` events, at most. If you encounter an `Error: HttpError: Resource
-not accessible by integration`, it's likely due to these permission constraints.
-To resolve this issue, you can modify the `on:` section of your workflow to use
-[`pull_request_target`](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target)
-instead of `pull_request` (see example [above](#create-workflow)). This change
-allows the action to have write access, because `pull_request_target` alters the
-[context of the
-action](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request_target)
-and safely grants additional permissions. Refer to the [GitHub token
-permissions
-documentation](https://docs.github.com/en/actions/security-guides/automatic-token-authentication#permissions-for-the-github_token)
-for more details about access levels and event contexts.
