bidi-checker-action

A GitHub action that checks for bi-directional unicode characters.

---

Summary

This action recursively checks the contents of the target repository for Unicode Bidi characters, and reports a successful run if none are present.

The checker uses the GITHUB_WORKSPACE environmental variable, defined in the GitHub Action Environmental Variables. By default, the directory this variable defines is empty, so must be populated via the actions/checkout GitHub Action for this checker to function properly. See the example usage below.

The checker will ignore the contents of generated .git directories.

Outputs

• Successful run if no bidi characters are present in code.
• Failed run if bidi characters are present in code.

Additional Outputs

time

The time in ms required to scan the repository.

Package for distribution

GitHub Actions will run the entry point from the action.yml. Packaging assembles the code into one file that can be checked in to Git, enabling fast and reliable execution and preventing the need to check in node_modules.

Actions are run from GitHub repos. Packaging the action will create a packaged action in the dist folder.

Run prepare

npm run prepare

Since the packaged index.js is run from the dist folder.

git add dist

Create a release branch

Users shouldn't consume the action from master since that would be latest code and actions can break compatibility between major versions.

Checkin to the v1 release branch

git checkout -b v1
git commit -a -m "v1 release"

git push origin v1

Your action is now published! 🚀

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

jobs:
  bidi_checker_job:
    runs-on: ubuntu-latest
    name: Check for bidi unicode characters in repo

      - name: Checkout repo
        uses: actions/checkout@v1
        id: checkout
      # Run the check for bidi characters.
      - name: Check for bidi characters
        id: bidi_check
