did-files-change

Action which outputs a value that indicates whether specific resources changed in a commit.

Why?

Because you may want to conditionally execute steps in a workflow only if certain files were changed.

How?

Call this step in a job to check whether certain files were changed.

You will then be able to check the status in subsequent steps, by checking if changed is equal to 1.

The value will be 0 if the files matched by the pathspec input parameter were not changed.

Example

name: My Workflow
on: push
      
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - name: Checkout
        # Checkout is required before did-files-change
        uses: actions/checkout@v2
        with:
          fetch-depth: 0
          # be sure to override the default value (1) for fetch-depth
      
      - name: Check changes
        id: check-changes
        uses: rdietrick/did-files-change@v1.3.3
        with:
          pathspec: test

      - name: Debug
        run: |
          echo "Changes detected in test directory: ${{ steps.check-changes.outputs.changed }}"

In the example above, steps.check-changes.outputs.changed will be set to 1 if the current commit included any files under the test directory in the repo.
