## Features
* Fast execution (0-10 seconds on average).
* Easy to debug.
* Scales to large repositories.
* Supports Git submodules.
* Escaped JSON output which can be used to run matrix jobs based on changed files.
* List changed directories.
* Restrict the max depth of matching changed directories.
* Write outputs to a `.txt` or `.json` file at a specified location for further processing.
* Monorepos (Fetches a fixed number of commits).
* Supports all platforms (Linux, MacOS, Windows).
* [GitHub-hosted runners](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners) support
* [GitHub Enterprise Server](https://docs.github.com/en/enterprise-server@3.3/admin/github-actions/getting-started-with-github-actions-for-your-enterprise/getting-started-with-github-actions-for-github-enterprise-server) support.
* [self-hosted runners](https://docs.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners) support.
* List all files and directories that have changed:
* Between the current pull request branch and the last commit on the target branch.
* Between the last commit and the current pushed change.
* Between the last remote branch commit and the current HEAD.
* Restrict change detection to a subset of files and directories:
* Boolean output indicating that certain files have been changed.
* Using [Glob pattern](https://docs.github.com/en/actions/learn-github-actions/workflow-syntax-for-github-actions#filter-pattern-cheat-sheet) matching.
* Globstar.
* Brace expansion.
## Usage
> **Warning**:
>
> * **IMPORTANT:** For `push` events when configuring [`actions/checkout`](https://github.com/actions/checkout#usage) the `fetch-depth` should be set to either `fetch-depth: 0` **OR** `fetch-depth: 2` depending on your use case.
> * For monorepos where pulling all the branch history might not be desired, you can omit [`actions/checkout`](https://github.com/actions/checkout#usage) - `fetch-depth` for `pull_request` events.
> * All multiline inputs should not use double or single quotes since the value is already a string seperated by a newline character. See [Examples](#examples) for more information.
> * Ensure that `persist-credentials` is set to `true` when configuring [`actions/checkout`](https://github.com/actions/checkout#usage) if `fetch-depth` isn't set to `0`.

## Versioning
This GitHub Action follows the principles of [Semantic Versioning](https://semver.org) for versioning releases.
The format of the version string is as follows:
major: is a major release number that indicates significant changes or new features that may not be backward compatible.
minor: is a minor release number that indicates minor changes or new features that are backward compatible.
patch : is a patch release number that indicates bug fixes or other small changes that are backward compatible.

## Known Limitation
> **Warning**:
>
> * Spaces in file names can introduce bugs when using bash loops. See: [#216](https://github.com/tj-actions/changed-files/issues/216)
> However, this action will handle spaces in file names, with a recommendation of using a separator to prevent hidden issues.

## Migration guide
With the switch from using grep's Extended regex to match files to the natively supported workflow glob pattern matching syntax introduced in [v13](https://github.com/tj-actions/changed-files/releases/tag/v13) you'll need to modify patterns used to match `files`.
```diff
...
- name: Get specific changed files
id: changed-files-specific
uses: tj-actions/changed-files@v24
with:
files: |
- \.sh$
- .(sql|py)$
- ^(dir1|dir2)
+ *.{sh,sql,py}
+ dir1
+ dir2
