Comprehensive Guide to Using GitHub Features: Gist, CLI, Actions, and Advanced Tips

GitHub is a fundamental platform for code hosting and collaboration, yet many users only treat it as a simple repository without leveraging its rich features. This guide collects useful GitHub tricks to improve productivity.

Gist is a sub‑service of GitHub that allows you to paste code snippets, generate a unique URL, and embed them in other pages with syntax highlighting. Each Gist has its own URL and can be shared via line‑number anchors (e.g., #L17 or #L17-L31).

Creating files via the web interface can be done with the create new file button, avoiding the need to push local changes.

File search is activated by pressing the T key, then typing the filename to quickly locate files in large repositories.

GitHub CLI enables command‑line interaction with GitHub. Installation examples:

$ brew install github/gh/gh
# update
$ brew update && brew upgrade gh

scoop bucket add github-gh https://github.com/cli/scoop-gh.git
scoop install gh

After installation, run gh auth login to authorize the CLI, then you can list issues ( gh issue list), create issues, filter them, and open them in a browser.

GitHub Actions provides CI/CD services. Key concepts include workflow, job, step, and action. An example workflow ( .github/workflows/ci.yml) builds a React app and deploys it to GitHub Pages using the JamesIves/github-pages-deploy-action@releases/v3 action, with environment variables ACCESS_TOKEN, BRANCH, and FOLDER.

    steps:

        uses: actions/checkout@v2
        with:
          persist-credentials: false
      - name: Install and Build
        run: |
          npm install
          npm run-script build
      - name: Deploy
        uses: JamesIves/github-pages-deploy-action@releases/v3
        with:
          ACCESS_TOKEN: ${{ secrets.ACCESS_TOKEN }}
          BRANCH: gh-pages
          FOLDER: build

Additional tips cover automatic issue closing via commit messages, creating issue and pull‑request templates, using the Wiki for documentation, viewing commit heatmaps, and recommended browser extensions such as Octotree, isometric‑contributions, and Enhanced GitHub.
