## changed-files

Effortlessly track all changed files and directories relative to a target branch, the current branch (preceding commit or the last remote commit), multiple branches, or custom commits returning **relative paths** from the project root using this GitHub action.

> \[!NOTE]
>
> *   This action solely identifies files that have changed for events such as [`pull_request*`, `push`, `merge_group`, `release`, and many more](#other-supported-events-electron). However, it doesn't detect pending uncommitted changes created during the workflow execution.
>
>     See: https://github.com/tj-actions/verify-changed-files instead.

## Features 🚀

*   Fast execution, averaging 0-10 seconds.
*   Leverages either [Github's REST API](https://docs.github.com/en/rest/reference/repos#list-commits) or [Git's native diff command](https://git-scm.com/docs/git-diff) to determine changed files.
*   Facilitates easy debugging.
*   Scales to handle large/mono repositories.
*   Supports Git submodules.
*   Supports [merge queues](https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/managing-a-merge-queue) for pull requests.
*   Generates escaped [JSON output for running matrix jobs](https://github.com/tj-actions/changed-files/blob/main/.github/workflows/matrix-example.yml) based on changed files.
*   Lists changed directories.
    *   Limits matching changed directories to a specified maximum depth.
    *   Optionally excludes the current directory.
*   Writes outputs to a designated `.txt` or `.json` file for further processing.
*   Restores deleted files to their previous location or a newly specified location.
*   Supports fetching a fixed number of commits, which improves performance.
*   Compatible with all platforms (Linux, MacOS, Windows).
*   Supports [GitHub-hosted runners](https://docs.github.com/en/actions/using-github-hosted-runners/about-github-hosted-runners).
*   Supports [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).
*   Supports [self-hosted runners](https://docs.github.com/en/actions/hosting-your-own-runners/about-self-hosted-runners).
*   Lists 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.
*   Restricts change detection to a subset of files and directories:
    *   Provides boolean output indicating changes in specific files.
    *   Uses [Glob pattern](https://codepen.io/mrmlnc/pen/OXQjMe) matching.
        *   Supports Globstar.
        *   Supports brace expansion.
        *   Supports negation.
    *   Uses [YAML](https://yaml.org/) syntax for specifying patterns.
        *   Supports [YAML anchors & aliases](https://github.com/tj-actions/changed-files/blob/main/test/changed-files.yml#L8-L12).
        *   Supports [YAML multi-line strings](https://github.com/tj-actions/changed-files/blob/main/test/changed-files.yml#L13-L16).

And many more...

## Usage 💻

> \[!IMPORTANT]
>
> *   **Push Events**: When configuring [`actions/checkout`](https://github.com/actions/checkout#usage), make sure to set [`fetch-depth`](https://github.com/actions/checkout#usage) to either `0` or `2`, depending on your use case.
> *   **Mono Repositories**: To avoid pulling the entire branch history, you can utilize the default [`actions/checkout`](https://github.com/actions/checkout#usage)'s [`fetch-depth`](https://github.com/actions/checkout#usage) of `1` for [`pull_request`](https://docs.github.com/en/actions/using-workflows/events-that-trigger-workflows#pull_request) events.
> *   **Quoting Multiline Inputs**: Avoid using single or double quotes for [multiline](https://github.com/tj-actions/changed-files/blob/main/test/changed-files.yml#L13-L16) inputs. The value is already a string separated by a newline character. Refer to the [Examples](#examples-) section for more information.
> *   **Credentials Persistence**: If [`fetch-depth`](https://github.com/actions/checkout#usage) is not set to 0, make sure to set [`persist-credentials`](https://github.com/actions/checkout#usage)  to `true` when configuring [`actions/checkout`](https://github.com/actions/checkout#usage).
> *   **Matching Files and Folders**: To match all files and folders under a directory, this requires a globstar pattern e.g. `dir_name/**` which matches any number of subdirectories and files.

  # Event `pull_request`: Returns all changed pull request files.

    # NOTE:
    # - This is limited to pull_request* events and would raise an error for other events.
    # - A maximum of 3000 files can be returned.

        id: changed-files
        uses: tj-actions/changed-files@v45
      # NOTE: `since_last_remote_commit: true` is implied by default and falls back to the previous local commit.

        env:
          ALL_CHANGED_FILES: ${{ steps.changed-files.outputs.all_changed_files }}

## Useful Acronyms 🧮

|  Acronym  |   Meaning    |
|:---------:|:------------:|
|     A     |    Added     |
|     C     |    Copied    |
|     M     |   Modified   |
|     D     |   Deleted    |

|     T     | Type changed |
|     U     |   Unmerged   |
|     X     |   Unknown    |

> \[!IMPORTANT]
>
> *   When using `files_yaml*` inputs:
>     *   it's required to prefix all outputs with the key to ensure that the correct outputs are accessible.
>
>         For example, if you use `test` as the key, you can access outputs like `added_files`, `any_changed`, and so on by prefixing them with the key `test_added_files` or `test_any_changed` etc.

## Important Notice ⚠️

> \[!IMPORTANT]
>
> *   Spaces in file names can introduce bugs when using bash loops. See: [#216](https://github.com/tj-actions/changed-files/issues/216)

## 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}/**
