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

• Easy to debug.
• 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

• ubuntu-*
• macos-*
• windows-*

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.
