## changed-files
Retrieve all changed files relative to the default branch (`pull_request*` based events) or the last remote commit (`push` based event) returning the **absolute path** to all changed files from the project root.
## Features
* Fast execution (0-2 seconds on average).
* Easy to debug.
* Boolean output indicating that certain files have been changed.
* Multiple repositories support.
* Runs on self hosted runners.
* GitHub Enterprise Server support.
* Monorepos (Fetches only the last remote commit).
* Supports all platforms (Linux, MacOS, Windows).
* 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.
* Between the last remote branch commit and the current HEAD.
* Restrict change detection to a subset of files.
* Report on files that have at least one change.
* 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.
> * When using `persist-credentials: false` with `actions/checkout@v2` you'll need to specify a `token` using the `token` input.
> * 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)

## Known Limitation
> NOTE: :warning:
>
> * Spaces in file names can introduce bugs when using bash loops. See: [Issue #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.
