python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"

# Render a markdown file
.venv/bin/md-to-pdf input.md -o output.pdf

# With a brand pack
.venv/bin/md-to-pdf input.md -o output.pdf --brand-pack path/to/brand

# Check available brands
.venv/bin/md-to-pdf brand list
```

## Features (v0.2.1)

### ✅ Core Rendering
- **AST-first architecture** — markdown-it-py parser → internal AST → ReportLab renderer
- **English + CJK text** — Full Unicode support with CJK font management
- **Code blocks** — Syntax-highlighted code fences with language labels
- **Tables** — Multi-cell tables with proper formatting
- **Images** — Embedded images with alt text support
- **Mermaid diagrams** — Block diagrams rendered via Kroki / Puppeteer / pure JS

### ✅ Watermarking & Audit

- **L2 XMP metadata** — Embedded EXIF/XMP watermark data
- **Audit logging** — JSON-format audit trails (user, timestamp, source hash)

### ✅ Deterministic Rendering
- `SOURCE_DATE_EPOCH` support for reproducible PDFs
- Platform-specific canonical testing (Linux/macOS/Windows)

### ✅ Documentation

## Installation

### From source (development)
```bash
git clone https://github.com/leiminray/md-to-pdf.git
cd md-to-pdf
python3 -m venv .venv
.venv/bin/pip install -e ".[dev]"
```

### Run tests
```bash
.venv/bin/pytest -v              # Run all tests (443 passing)
.venv/bin/ruff check src/        # Lint
.venv/bin/mypy --strict src/     # Type check
```

## Architecture

```
markdown input
    ↓
markdown-it-py parser
    ↓
Internal AST (Document + outline)
    ↓
Transformer pipeline (strip frontmatter, collect headings, etc.)
    ↓
ReportLab renderer
    ↓
PDF output (with watermark/audit metadata)
```

## Python API

```python
from mdpdf.pipeline import Pipeline, RenderRequest, RenderFormat

# Render markdown to PDF
request = RenderRequest(
    markdown_path="input.md",
    output_path="output.pdf",
    brand_pack_dir="path/to/brand",  # optional
    watermark_user="alice@example.com",  # optional
)

pipeline = Pipeline()
result = pipeline.render(request)

if result.success:
    print(f"✓ Rendered to {result.output_path}")
else:
    print(f"✗ Error: {result.error_message}")
```

## CLI Commands

### Render
```bash
md-to-pdf INPUT.md -o OUTPUT.pdf [options]

Options:
  --brand-pack-dir PATH    Brand pack directory (theme, fonts, logos)
  --watermark-user NAME    User identifier for watermark
  --deterministic          Reproducible PDF output (SOURCE_DATE_EPOCH)
  --json                   Output structured JSON result
```

### Brand Management
```bash
md-to-pdf brand list                    # List available brands
md-to-pdf brand show BRAND_ID           # Show brand details
md-to-pdf brand migrate SRC DST         # Migrate  brand kit to v0.2 format
md-to-pdf brand validate PATH           # Validate brand pack schema
```

## What's Coming

**Planned for v0.3–v1.0:**
- Multiple rendering engines (WeasyPrint, etc.)
- Template packs (quote, user-manual, certificate, etc.)
- L3/L4/L5 advanced watermarking (steganography, encryption, signatures)
- MCP server, GitHub Action, Docker images
- GitHub Pages / PDF/A-2b compliance
- Policy-based brand locking, audit export

See [roadmap spec](docs/superpowers/specs/2026-04-25-md-to-pdf-v2.x-roadmap.md) for full vision.
