files-changed-action

This action diffs 2 configured commits and outputs whether any of the files match the regex passed into the workflow. Exclusions are applied before inclusions. This action may be useful for determining whether subsequent actions should run. The regex style is whatever grep accepts.

Usage

Make sure you set the correct fetch-depth for actions/checkout. Otherwise, you may attempt to diff against a commit that does not exist in the repository running in the action. See more at actions/checkout.

Also refer to events that trigger workflows to understand which fields in the GitHub metadata contains the SHAs of commits you want to compare.

steps:
- uses: actions/checkout@v3
  with:
    fetch-depth: 2
- uses: chrisyxlee/files-changed-action@v0.0.4
  with:
    # A list of files to look for.
    include: |
      .*\.go$
      go.sum$
      go.mod$
    # A list of files to exclude from diffs.
    exclude: |
      .*_test.go$
    # The commit containing the latest changes.
    head_ref: ${{ github.event.pull_request.head.sha }}
    # The commit containing the base changes to compare against.
    base_ref: ${{ github.event.pull_request.base.sha }}
    # Suppress logs if you anticipate many files changing.
    output_diffs: ''
