changed-files

Get all modified files relative to the default branch (pull_request* events) or last commit (push event).

Features

• 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 all changed.
  • Report on files that have at least one file change.
  • Regex pattern matching on a subset of files.

Usage

NOTE: ⚠️

• For push events to work 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 action you need to specify the token using the token input.
