Markdown to PDF Converter

Convert Markdown to PDF with Chinese font support and customizable styling.

Quick Start

The script uses uv inline metadata – no manual dependency installation needed:

# Basic conversion (uv auto-installs dependencies)
uv run scripts/md2pdf.py input.md output.pdf

# With custom CSS
uv run scripts/md2pdf.py input.md output.pdf --style assets/vintage-paper.css

# With custom title
uv run scripts/md2pdf.py input.md output.pdf --title "Chapter Title"

# Or make executable and run directly
chmod +x scripts/md2pdf.py
./scripts/md2pdf.py input.md output.pdf

Note: On macOS, the script automatically configures Homebrew library paths.

Available Styles

Two pre-built styles in assets/:

Default Style Features

The built-in default style (vintage paper) includes:

• Background: Warm cream (#FAF6F0)
• Text color: Dark brown (#4A3728)
• Heading color: Darker brown (#3D2B1F)
• Font: Chinese serif (Noto Serif SC, Songti SC)
• Line height: 1.8
• Paragraph indent: 2em (Chinese style)
• Page footer: Page numbers

Customization

To customize styling, copy an existing CSS file and modify:

@page {
    size: A4;                        /* Paper size */
    margin: 2.5cm 2cm;               /* Page margins */
    background-color: #FAF6F0;       /* Page background */
}

body {
    font-family: "Noto Serif SC", serif;  /* Font stack */
    font-size: 12pt;                      /* Base font size */
    line-height: 1.8;                     /* Line spacing */
    color: #4A3728;                       /* Text color */
}

Chinese Font Priority

The converter uses this font fallback chain:

1. Noto Serif SC (Google Noto fonts)
2. Source Han Serif SC (Adobe fonts)
3. Songti SC (macOS)
4. STSong (macOS)
5. SimSun (Windows)

Ensure at least one of these fonts is installed on the system.
