## changed-files
Retrieve all changed files relative to the target 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.
* Scales to large repositories.
* Git submodules support.
* 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 that have changed:
* Between the current pull request branch and the last commit on the target branch.
* Between the current pull request branch and the fork point 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:
* 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:
>
> * 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.
> 
## Versioning
This project follows a `v(major).(patch)` versioning scheme with the exception of pointing the git ref of the latest patch release to the major version tag.
> NOTE: :warning:
>
> * Users referencing the legacy `v1.x.x` -> `v5.0.0` semantic versions, are required to switch over to `v10.x` -> `v15.x` respectively as new releases would no longer be deployed using the old versioning scheme.
> * A breaking change was introduced in `v1.1.4` and `v13.x` which has been fixed.
## Migration guide
With the switch from using grep's Extended regex to match files to the natively supported workflow glob pattern matching snytax introduced in [v13](https://github.com/tj-actions/changed-files/releases/tag/v13) you'll need to modify patterns used to match `files`.
**BEFORE**
```yml
...
- name: Get specific changed files
id: changed-files-specific
uses: tj-actions/changed-files@v12.2
with:
files: |
\.sh$
.(sql|py)$
^(mynewfile|custom)
```
**AFTER**
```yml
...
- name: Get specific changed files
id: changed-files-specific
uses: tj-actions/changed-files@v21
with:
files: |
*.sh
*.sql
*.py
mynewfile
custom/**
```
