# CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

## Overview

This is a Jekyll-based blog/portfolio site built with a custom theme called "pivoine". The site combines Ruby (Jekyll) for static site generation with a modern JavaScript/TypeScript build system using webpack and pnpm workspaces.

## Build & Development Commands

### Jekyll (Ruby) Commands
```bash
# Install Ruby dependencies
bundle install

# Serve the site locally (development mode)
bundle exec jekyll serve

# Build the site with LSI (latent semantic indexing) for related posts
bundle exec jekyll build --lsi

# Note: The site uses KaTeX for math rendering which requires Node.js runtime
```

### JavaScript/CSS Build Commands
```bash
# Install all dependencies (including workspace packages)
pnpm install

# Build everything (JS + CSS + scripts)
pnpm run build

# Build only JavaScript (modern + legacy bundles)
pnpm run build:js

# Build only CSS
pnpm run build:css

# Build workspace dependencies first, then main project
pnpm run build:all

# Development mode with auto-rebuild
pnpm run dev
# or
pnpm run watch

# Watch JS only
pnpm run watch:js

# Watch CSS only
pnpm run watch:css

# Format JavaScript code
pnpm run format

# Clean built JS files
pnpm run clean
```

## Architecture

### Monorepo Structure
The project uses pnpm workspaces with local packages under `packages/`:
- `packages/hydecorp/component` - Base web component library
- `packages/hydecorp/drawer` - Drawer component
- `packages/hydecorp/push-state` - Push state navigation
- `packages/honeymachine/search` - Search functionality

These workspace packages are referenced with `workspace:*` protocol in package.json.

### JavaScript Build System
The webpack configuration (`webpack.config.js`) creates **two bundles**:
1. **Modern bundle** (`pivoine-{version}.js`) - Targets ES modules-compatible browsers
2. **Legacy bundle** (`LEGACY-pivoine-{version}.js`) - Targets IE11+ with full polyfills

Entry point: `_js/src/entry.js`

JavaScript source files in `_js/src/` include:
- `common.js` - Shared utilities
- `drawer.js` - Drawer navigation
- `push-state.js` - SPA-like navigation
- `search.js` - Search integration
- `dark-mode.js` - Theme switching
- `sound.js` - Sound effects
- `lightbox.js` - Image lightbox
- `clap-button.js` - GetClaps integration

### CSS Build System
CSS is built via `.scripts/build-css.js` which processes SCSS files from `_sass/`:
- Main entry points: `html.scss`, `my-style.scss`, `my-inline.scss`
- Uses inline/link comments to control how CSS is included
- Custom variables in `_sass/my-variables.scss`
- Theme SCSS in `_sass/pivoine/` and `_sass/pooleparty/`

### Jekyll Structure
- `_config.yml` - Main Jekyll configuration with pivoine theme settings
- `_layouts/` - Page templates (base, post, page, blog, etc.)
- `_includes/` - Reusable HTML partials
- `_posts/` - Blog posts organized by category folders (devilish, palina, odinsland, souls, sketches, music)
- `_pages/` - Static pages
- `_data/` - YAML data files (authors, strings, variables, social, countries, sounds)
- `_sass/` - SCSS stylesheets

### Content Organization
Posts are organized into featured categories defined in `_config.yml`:
- Palina
- Odinsland
- Devilish
- Souls
- Sketches
- Music

Each post's URL follows the pattern: `/:categories/:slug`

### Key Configuration Details
- **Math rendering**: Uses `kramdown-math-katex` (requires Node.js runtime)
- **Search**: Disabled in development, enabled in production via `JEKYLL_ENV=production`
- **Dark mode**: Dynamic based on OS settings with manual toggle
- **Pagination**: 5 posts per page using jekyll-paginate-v2
- **Analytics**: Umami integration configured
- **Related posts**: LSI-based (use `--lsi` flag when building)

## Development Workflow

1. **Initial setup**:
   ```bash
   bundle install
   pnpm install
   pnpm run build:all
   ```

2. **Development**:
   ```bash
   # Terminal 1: Watch and rebuild JS/CSS
   pnpm run dev

   # Terminal 2: Run Jekyll server
   bundle exec jekyll serve
   ```

3. **Production build**:
   ```bash
   pnpm run build:all
   JEKYLL_ENV=production bundle exec jekyll build --lsi
   ```

## Deployment

The site deploys to GitHub Pages via `.github/workflows/jekyll-gh-pages.yml`. The workflow builds both the JavaScript assets and the Jekyll site, then deploys to `pivoine.art` (configured via CNAME).

## Important Notes

- The site uses Node.js version specified in `.nvmrc`
- JavaScript builds create versioned filenames based on package.json version
- Some files are auto-generated (look for "AUTOGENERATED" headers)
- Custom scripts in `.scripts/` directory handle specialized build tasks
- Prettier is configured for JS formatting (`.prettierrc`)
- RuboCop is configured for Ruby linting (`.rubocop.yml`)
