v1.7.5

• Strictly check available contexts in ${{ }} placeholders following the 'Context availability' table in the official document.
  • For example, jobs.<job_id>.defaults.run.shell allows env context but shell workflow keys in other places allow no context.

    defaults:
      run:
        # ERROR: No context is available here
        shell: ${{ env.SHELL }}
    
    jobs:
      test:
        runs-on: ubuntu-latest
        defaults:
          run:
            # OK: 'env' context is available here
            shell: ${{ env.SHELL }}
        steps:
          - run: echo hello
            # ERROR: No context is available here
            shell: ${{ env.SHELL}}

• Check a string literal passed to fromJSON() call. This pattern is popular to create array or object constants because GitHub Actions does not provide the literal syntax for them. See the document for more details. (#464)

  jobs:
    test:
      # ERROR: Key 'mac' does not exist in the object returned by the fromJSON()
      runs-on: ${{ fromJSON('{"win":"windows-latest","linux":"ubuntul-latest"}')['mac'] }}
      steps:
        - run: echo This is a special branch!
          # ERROR: Broken JSON string passed to fromJSON.
          if: contains(fromJSON('["main","release","dev"'), github.ref_name)

• Allow passing command arguments to -shellcheck argument. (#483, thanks @anuraaga)
  • This is useful when you want to use alternative build of shellcheck like go-shellcheck.

    actionlint -shellcheck="go run github.com/wasilibs/go-shellcheck/cmd/shellcheck@latest"

• Support undocumented repository_visibility, artifact_cache_size_limit, step_summary, output, state properties in github context. (#489, thanks @rasa for adding repository_visibility property)
• Remove macos-12 runner label from known labels because it was dropped from GitHub-hosted runners on Dec. 3 and is no longer available.
• Add windows-2025 runner label to the known labels. The runner is in public preview. (#491, thanks @ericcornelissen)
• Add black to the list of colors for branding.color action metadata. (#485, thanks @eifinger)
• Add table to the list of icons for branding.icon action metadata.
• Fix parsing escaped { in format() function call's first argument.
• Fix the incorrect join() function overload. join(s1: string, s2: string) was wrongly accepted.
• Update popular actions data set to the latest.
  • Add download-artifact/v3-node20 to the data set. (#468)
  • Fix missing the reviewdog/action-hadolint@v1 action input. (#487, thanks @mi-wada)
• Link to the documents of the stable version in actionlint man page and -help output.
• Refactor LintStdin() API example and some unit tests. (#472, #475, thanks @alexandear)
• Improve the configuration example in actionlint.yaml document to explain glob patterns for paths. (#481)
