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.
  • Git submodules (TODO)
  • Multiple repositories support.
  • GitHub-hosted runners support
  • GitHub Enterprise Server support.
  • self-hosted runners 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 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 matching.

Usage

NOTE: ⚠️

  • 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

Known Limitation

NOTE: ⚠️

  • 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

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: ⚠️

  • 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.
