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.
• 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 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 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.
