## changed-files
Retrieve all changed files relative to the default branch (`pull_request*` events) or a previous commit (`push` event) returning the **absolute path** to all changed files from the project root.
## Features
* List all files that have changed.
* Between the current pull request branch and the default branch.
* Between the last commit and the current pushed change.
* Restrict change detection to a subset of files.
* Report on files that have at least one change.
* [Regex pattern](https://www.gnu.org/software/grep/manual/grep.html#Regular-Expressions) matching on a subset of files.
## Supported Platforms
* [`ubuntu-*`](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idruns-on)
* [`macos-*`](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idruns-on)
* [`windows-*`](https://docs.github.com/en/actions/reference/workflow-syntax-for-github-actions#jobsjob_idruns-on)
## Usage
> NOTE: :warning:
>
> * **IMPORTANT:** For `push` events to work you need to include `fetch-depth: 0` **OR** `fetch-depth: 2` depending on your use case.
> * When using `persist-credentials: false` with `actions/checkout@v2` you'll need to specify a `token` using the `token` input.
