gen-pack-action

GitHub workflow action to generate documentation and packs

The composite action runs the usual steps for generating documentation and pack archives:

1. Installs required tools like doxygen and packchk.
2. Generates the documentation if a generator script is provided.
3. Checks hyperlinks in the generated documentation if a checker script is provided.
4. Archives the documentation if the output path is provided.
5. Generates the Open-CMSIS-Pack pack if a generator script is provided.
6. Archives the generated pack if the output folder is provided.
7. Publishes the documentation to GH-Pages if documentation path and branch are provided.

Usage

- uses: Open-CMSIS-Pack/gen-pack-action@main
  with:
    doxygen-version: 1.9.2                                  # default
    packchk-version: 1.3.95                                 # default
    gen-doc-script: ./DoxyGen/gen_doc.sh                    # skipped by default
    check-links-script: ./Documentation/check_links.sh      # skipped by default
    doc-path: ./Documentation/html                          # skipped by default
    gen-pack-script: ./gen_pack.sh                          # skipped by default
    gen-pack-output: ./output                               # skipped by default
    gh-pages-branch: gh-pages                               # default
    gh-pages-deploy: gh-pages.yml                           # default

Attention for Windows users

On Windows Bash scripts are executable without special handling. This does not hold true once moving the files to a Linux machine. To assure the eXecute permission gets set on Linux, run the following Git command on the Windows machine and commit the change:

git update-index --chmod=+x <script>

As a starting point you can use the workflow template and add it to your projects GitHub repository under .github/workflows/. For details about documentation handling, see below.

Advanced usage

Doxygen download

If Doxygen is not required one can skip download and installation by setting doxygen-version: none.

The URL Doxygen is downloaded from can be overwritten with the action input parameter doxygen-url which defaults to https://sourceforge.net/projects/doxygen/files/rel-{VERSION}/doxygen-{VERSION}.linux.bin.tar.gz/download. The {VERSION} pattern is substituted with the value provided in doxygen-version.

Publish to GitHub Pages

Publishing documentation to GitHub Pages is handled automatically via the settings

• gen-doc-script for generating if required, leave empty to skip generation.
• doc-path for archiving documentation, leave empty to skip archiving/publishing.
• gh-pages-branch for publishing to GitHub Pages, set to empty to skip publishing.
• gh-pages-deploy for trigger GitHub Pages deploy workflow, set to emtpy to skip.

Once the settings are given, the workflow will commit the generated documentation from doc-path into a subfolder onto the gh-pages-branch. After pushing back the gh-pages-deploy is triggered to issue actual pages deployment. Check your repositories settings Pages > Build and Deployment > Source is set to GitHub Action.

The repository needs to be prepared for GitHub Pages as the following:

• Create orphaned gh-pages branch:

  # git checkout --orphan gh-pages
  Switched to a new branch 'gh-pages'
  # git reset
  

• Provide initial content taken from the templates:
  • The .github/workflows/gh-pages.yml deploy workflow.
  • An index.html with front page or redirection to latest.
  • The update_versions.sh shell script. Assure execute flag is set. On Windows use git update-index --chmod=+x <script> to record the execte flag, properly.
  • The versions.js.in JavaScript template.
  • Some initial content e.g. for main branch in folder main.
  • A latest symlink pointing to initial content folder.
• Commit and push documentation branch:

  # git add .github index.html update_versions.sh versions.js.in main latest
  # git commit -m "Initial contribution"
  # git push origin gh-pages:gh-pages
  

• Switch back to main branch and add the .github/workflows/gh-pages.yml deploy workflow there as well:

  # git checkout main
  Switched to branch 'main'
  # git add .github/workflows/gh-pages.yml
  # git commit -m "Add GitHub Pages deploy workflow"
  # git push
