Adds GitHub Actions workflows to automate testing, linting, and publishing of Jupyter notebooks as static HTML sites with per-branch isolation on GitHub Pages.

Workflows

  • .github/workflows/ci.yml - Runs on main branch push/PR:

    • Executes flake8 linting and pytest tests
    • Validates all notebooks execute without errors
    • Minimal permissions (contents: read)

  • .github/workflows/deploy-notebooks-pages.yml - Runs on all branch pushes:

    • Converts notebooks to HTML via scripts/build_notebooks.py
    • Deploys to gh-pages branch under <branch-name>/ subdirectory
    • Generates top-level index listing all published branches
    • Creates/initializes gh-pages branch if missing

Script

scripts/build_notebooks.py recursively finds and processes notebooks:

# Preserves directory structure by encoding paths
html_name = nb.replace('/', '_').replace('.ipynb', '.html')

# Failed notebooks get error pages instead of breaking builds
except subprocess.CalledProcessError as e:
    with open(html_path, 'w') as f:
        f.write(f"<html><body><h1>Execution failed for {nb}</h1><pre>{e}</pre></body></html>")

Creates index.html showing build status (✓/✗) for each notebook.

Dependencies

requirements.txt specifies: jupyter, nbconvert, nbformat, pytest, flake8

.gitignore excludes build artifacts (site/, gh-pages/), Python cache, and temporary files.

Original prompt

Add CI, notebook build and deployment workflows, supporting scripts, tooling, and documentation to enable building, testing, linting, and publishing Jupyter notebooks as branch-specific HTML pages on GitHub Pages.

Repository: Notebook pages (branch-per-branch)

This repository contains many Jupyter notebooks. This change adds CI and an automated build-and-deploy workflow that runs on pushes to any branch and publishes rendered HTML pages for that branch under gh-pages/.

Files added:

  • .github/workflows/ci.yml — runs lint/tests and executes notebooks on pushes/PRs to main.
  • .github/workflows/deploy-notebooks-pages.yml — builds and deploys per-branch HTML pages to gh-pages when any branch is pushed.
  • scripts/build_notebooks.py — script that executes notebooks and exports them to HTML.
  • requirements.txt, Dockerfile, .pre-commit-config.yaml, .gitignore — tooling and environment files.

How to run locally:

  1. python -m venv .venv
  2. source .venv/bin/activate
  3. pip install -r requirements.txt
  4. python scripts/build_notebooks.py site/local-branch

Enable GitHub Pages to serve the gh-pages branch in repository Settings -> Pages. The per-branch pages will be available at https://.github.io/// .

Please create a feature branch (name it ci/add-notebook-pages) from main, add these files, commit them, and open a pull request titled "Add CI, notebook build scripts, and branch-per-branch GitHub Pages deployment" targeting main. The PR description should summarize the above problem_statement and list the files added.

Do not modify other repository files. If any file path already exists, update it to match the content above.

After creating the PR, please return the PR URL and the list of files added or changed with permalinks to the branch blobs in the PR branch.
