KB4IT incremental compiling in Github (experimental)

Excerpt

These days, after several fixes, I was able to produce a reliable incremental compiling of my knowledge base repositories (or force a whole compilation of the whole KB, if the app meets some conditions).

To my initial surprise, it didn’t work in Github.

Github actions

In Github, when a new update is detected in the source directory, the Github action in charge (update-blog.yml) of updating the website is executed.

GitHub Actions runners are ephemeral. Every workflow run starts on a fresh VM, so anything written to disk is lost unless you explicitly persist it somewhere.

Solution

Now, instead using .kb4it directory under $USER directory, it uses the own Github repository. Then, once kb4it finishes the compilation, all changes are pushed automatically.

      # Commit changes
      - name: Commit and push changes (if any)
        run: |
          git config --global user.name 'github-actions[bot]'
          git config --global user.email 'github-actions[bot]@users.noreply.github.com'

          # Stage all changes in docs/
          git add docs/
          git add var/

          # Check if there are changes to commit
          if git diff --staged --quiet; then
            echo "No changes to commit."
          else
            git commit -m "Auto-update target/ after KB4IT build [$(date -u)]"
            git push
          fi
