## changed-files
Retrieve all changed files and directories relative to the target branch or the last remote commit returning the **absolute path** from the project root.
## Features
* Fast execution (0-2 seconds on average).
* Easy to debug.
* Scales to large repositories.
* Git submodules support.
* No extra API calls.
* Escaped JSON Output which can be used for running matrix jobs based on changed files.
* List only changed directories.
* Monorepos (Fetches only the last remote commit).
* 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.
## Usage
> NOTE: :warning:
>
> * **IMPORTANT:** For `push` events you need to include `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 `fetch-depth` for `pull_request` events.
> * For files located in a sub-directory ensure that the pattern specified contains `**/` (globstar) to match any preceding directories or explicitly pass the full path relative to the project root. See: [#314](https://github.com/tj-actions/changed-files/issues/314).
> * All multiline inputs should not use double or single qoutes since the value is already a string seperated by a newline character. See [Examples](#examples) for more information.

## Known Limitation
> NOTE: :warning:
>
> * Using characters like `\n`, `%`, `.` and `\r` as separators would be [URL encoded](https://www.w3schools.com/tags/ref_urlencode.asp)
> * 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.
