Examples

Including a subdirectory

You can limit your find and replace to a directory.

name: My Workflow
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Find and Replace
        uses: jacobtomlinson/gha-find-replace@v2
        with:
          find: "hello"
          replace: "world"
          include: "justthisdirectory/**"
          regex: true

Filter by file name

You can limit your find and replace to just files with a specific name.

name: My Workflow
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Find and Replace
        uses: jacobtomlinson/gha-find-replace@v2
        with:
          find: "hello"
          replace: "world"
          include: "**README.md" # Will match all README.md files in any nested directory

Exclude by file type

You can set your find and replace to ignore certain file types.

name: My Workflow
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Find and Replace
        uses: jacobtomlinson/gha-find-replace@v2
        with:
          find: "hello"
          replace: "world"
          exclude: "**/*.py" # Do not modify Python files

Pushing changes back

Any modifications during a GitHub Actions workflow are only made to the working copy checked out by the actions/checkout step. If you want those changes to be pushed back to the repository you'll need to add a final step that does this.

name: My Workflow
on: [push, pull_request]
jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v2
      - name: Find and Replace
        uses: jacobtomlinson/gha-find-replace@v2
        with:
          find: "hello"
          replace: "world"
          regex: false
      - name: Push changes
        uses: ad-m/github-push-action@v0.6.0
        with:
          github_token: ${{ secrets.GITHUB_TOKEN }}
          branch: ${{ github.ref }}

If you need the push event to trigger other workflows, use a repo scoped Personal Access Token.

      - name: Push changes
        uses: ad-m/github-push-action@v0.6.0
        with:
          github_token: ${{ secrets.MY_PAT }}
          branch: ${{ github.ref }}

Publishing

To publish a new version of this Action we need to update the Docker image tag in action.yml and also create a new release on GitHub.

• Work out the next tag version number.
• Update the Docker image in action.yml.
• Create a new release on GitHub with the same tag.
