changed-files

Retrieve all changed files and directories relative to the target branch or the last remote commit returning the absolute paths from the project root.

Features

  • Fast execution (0-2 seconds on average).
  • Easy to debug.
  • Scales to large repositories.
  • Git submodules support.
  • Escaped JSON Output which can be used for running matrix jobs based on changed files.
  • Optionally list only changed directories.
  • Restrict the max depth of changed directories.
  • Monorepos (Fetches only the last remote commit).
  • Supports all platforms (Linux, MacOS, Windows).
  • GitHub-hosted runners support
  • GitHub Enterprise Server support.
  • 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 matching.

Usage

NOTE: ⚠️

  • 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.
  • All multiline inputs should not use double or single qoutes since the value is already a string seperated by a newline character. See Examples for more information.

Known Limitation

NOTE: ⚠️

  • Using characters like \n, %, . and \r as separators would be URL encoded
  • Spaces in file names can introduce bugs when using bash loops. See: #216 However, this action will handle spaces in file names, with a recommendation of using a separator to prevent hidden issues. Screen Shot 2021-10-23 at 9 37 34 AM

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 you'll need to modify patterns used to match files.

BEFORE

...

      - name: Get specific changed files
        id: changed-files-specific
        uses: tj-actions/changed-files@v12.2
        with:
          files: |
            \.sh$
            .(sql|py)$
            ^(mynewfile|custom)            

AFTER

...

      - name: Get specific changed files
        id: changed-files-specific
        uses: tj-actions/changed-files@v24
        with:
          files: |
            *.sh
            *.sql
            *.py
            mynewfile
