changed-files

Retrieve all changed files relative to the default branch (pull_request* based events) or a previous commit (push based event) returning the absolute path to all changed files from the project root.

Features

  • Boolean output indicating that certain files have been modified.
  • 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.
  • Restrict change detection to a subset of files.
    • Report on files that have at least one change.
    • Regex pattern matching on a subset of files.

Supported Platforms

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.
