Action Summary

This GitHub Action retrieves and outputs the programming languages used in a repository by leveraging GitHub’s “List repository languages” API endpoint. It automates tasks such as generating a list of repository languages or creating workflows based on those languages, streamlining language-specific job execution in CI/CD pipelines. Key capabilities include language output as JSON or CodeQL-compatible formats and customization for language-specific build configurations.

What’s Changed

Highlights

  • New: GitHub Actions workflow scanning support — detects .github/workflows/*.{yml,yaml} files and injects actions as a CodeQL pseudo-language into the matrix output with build-mode: none. Enables CodeQL scanning of workflow files themselves in custom/advanced setups.
  • Runtime upgrade: Node 20 → Node 24 — addresses GitHub’s deprecation of Node 20 for actions.

Why actions matters

CodeQL has supported scanning GitHub Actions workflow files as a distinct actions language since mid-2024. The GitHub /repos/{owner}/{repo}/languages endpoint (backed by Linguist) does not report actions — workflow YAMLs show up only as generic YAML and are filtered out. This release adds manual detection so custom/advanced CodeQL setups get the same coverage GitHub’s default setup auto-enrollment provides.

Output matrix change

Repos with workflow files will now see an additional matrix entry from languages_codeql_w_buildmode:

{
  "language": "actions",
  "build-mode": "none",
  "manual-build-command": "",
  "vpn-connection": false,
  "pre-commands": [],
  "env-vars": {},
  "build-setup": []
}

Repos without .github/workflows/ are unaffected.

Breaking changes

None. However, CodeQL analysis matrices driven by this action’s output will gain one additional short-running job per repo that has workflow files. This is the intended outcome.
