# Build Scripts
This directory contains two generators that turn the tutorial markdown files
into distributable formats:
- [**EPUB Builder**](#epub-builder-script) — `build_epub.py`
- [**Static Website Builder**](#static-website-builder) — `build_website.py`
Both treat the `.md` files as the single source of truth — re-run the relevant
script after editing markdown to regenerate the output.

# EPUB Builder Script
Build an EPUB ebook from the Claude How-To markdown files.
## Features
- Organizes chapters by folder structure (01-slash-commands, 02-memory, etc.)
- Renders Mermaid diagrams as PNG images via Kroki.io API
- Async concurrent fetching - renders all diagrams in parallel
- Generates a cover image from the project logo
- Converts internal markdown links to EPUB chapter references
- Strict error mode - fails if any diagram cannot be rendered
## Requirements
- Python 3.10+
- [uv](https://github.com/astral-sh/uv)
- Internet connection for Mermaid diagram rendering
## Quick Start
```bash
# Simplest way - uv handles everything
uv run scripts/build_epub.py
```
## Development Setup
```bash
# Create virtual environment
uv venv
# Activate and install dependencies
source .venv/bin/activate
uv pip install -r requirements-dev.txt
# Run tests
pytest scripts/tests/ -v
# Run the script
python scripts/build_epub.py
```
## Command-Line Options
```
usage: build_epub.py [-h] [--root ROOT] [--output OUTPUT] [--verbose]
[--timeout TIMEOUT] [--max-concurrent MAX_CONCURRENT]
options:
-h, --help show this help message and exit
--root, -r ROOT Root directory (default: repo root)
--output, -o OUTPUT Output path (default: claude-howto-guide.epub)
--verbose, -v Enable verbose logging
--timeout TIMEOUT API timeout in seconds (default: 30)
--max-concurrent N Max concurrent requests (default: 10)
```
## Examples
```bash
# Build with verbose output
uv run scripts/build_epub.py --verbose
# Custom output location
uv run scripts/build_epub.py --output ~/Desktop/claude-guide.epub
# Limit concurrent requests (if rate-limited)
uv run scripts/build_epub.py --max-concurrent 5
```
## Output
Creates `claude-howto-guide.epub` in the repository root directory.
The EPUB includes:
- Cover image with project logo
- Table of contents with nested sections
- All markdown content converted to EPUB-compatible HTML
- Mermaid diagrams rendered as PNG images
## Running Tests
```bash
# With virtual environment
source .venv/bin/activate
pytest scripts/tests/ -v
# Or with uv directly
uv run --with pytest --with pytest-asyncio \
--with ebooklib --with markdown --with beautifulsoup4 \
--with httpx --with pillow --with tenacity \
pytest scripts/tests/ -v
```
## Dependencies
Managed via PEP 723 inline script metadata:
| Package | Purpose |
|---------|---------|
| `ebooklib` | EPUB generation |
| `markdown` | Markdown to HTML conversion |
| `beautifulsoup4` | HTML parsing |
| `httpx` | Async HTTP client |
| `pillow` | Cover image generation |
| `tenacity` | Retry logic |
## Troubleshooting
**Build fails with network error**: Check internet connectivity and Kroki.io status. Try `--timeout 60`.
**Rate limiting**: Reduce concurrent requests with `--max-concurrent 3`.
**Missing logo**: The script generates a text-only cover if `claude-howto-logo.png` is not found.

# Static Website Builder
Generate an elegant, mobile-friendly static website from the same markdown
files used by the EPUB build. The website is the rendered view; the `.md`
files remain the single source of truth.
## Features
- One HTML page per markdown source — internal `.md` links are rewritten to
the corresponding pages on the site
- References to non-markdown repo files (templates, scripts, JSON) become
GitHub blob URLs that open the source on github.com
- Mermaid diagrams render client-side via `mermaid.min.js`, served from the
built site (no CDN at runtime)
- Tailwind CSS compiled with the standalone CLI (Go binary, no Node.js) and
served from the built site — responsive layout with sidebar nav, in-page
TOC, dark mode toggle, and prev/next page navigation
- Inter + JetBrains Mono fonts are self-hosted alongside the CSS — no
third-party requests at page load
- Mirrors the EPUB curriculum order (`01-` … `10-` plus top-level docs)
- Hostable as plain static files — designed to deploy to GitHub Pages
## Quick Start
```bash
# Build the English website into ./site/
uv run scripts/build_website.py
# Preview locally
python -m http.server --directory site 8080
# then open http://localhost:8080
```
## Command-Line Options
```
usage: build_website.py [-h] [--root ROOT] [--output OUTPUT]
[--lang {en,vi,zh,ja,uk}] [--repo-url REPO_URL]
[--branch BRANCH] [--verbose]
options:
--root, -r ROOT Source root (default: repo root)
--output, -o OUTPUT Output directory (default: /site)
--lang LANG Language to build: en | vi | zh | ja | uk
--repo-url URL GitHub repo for blob links (default: luongnv89/claude-howto)
--branch BRANCH Branch for blob links (default: main)
--verbose, -v Enable verbose logging
```
## GitHub Pages Deploy
The repo ships a workflow at `.github/workflows/pages.yml` that builds the
site on every push to `main` (when any `.md` or generator file changes) and
publishes via `actions/deploy-pages`. Enable GitHub Pages in repo settings
with **Source: GitHub Actions** to activate it.
## Architecture
`build_website.py` reuses the chapter-ordering logic from `build_epub.py` and
ships HTML templates under `scripts/website_templates/`:
- `page.html.j2` — per-page Jinja2 template with sidebar nav, TOC, prev/next
- `tailwind.config.js`, `tailwind.input.css` — config + entry CSS for the
Tailwind standalone CLI; the CLI scans the built HTML and produces
`site/assets/tailwind.css` with just the utilities actually used
- `site.css` — small layer of site-specific styles plus Pygments theme
The Tailwind CLI binary, Mermaid bundle, and font files are downloaded on
first build into `scripts/.vendor-cache/` (gitignored) — see
`scripts/vendor_assets.py`.
Heading anchors are generated using the exact algorithm in
`check_cross_references.heading_to_anchor`, so `#anchor` links validated by
the pre-commit hook resolve correctly on the rendered site.
