# md2pdf
Convert Markdown → PDF via Pandoc + XeLaTeX. Full LaTeX math + CJK support.
## Prerequisites
System packages (apt):
```
pandoc texlive-xetex texlive-fonts-recommended texlive-fonts-extra texlive-latex-extra texlive-lang-chinese
```
## Quick Convert
```bash
bash <skill_dir>/scripts/md2pdf.sh input.md output.pdf
```
The script auto-detects CJK content, picks suitable fonts, sanitizes emoji, adds TOC, and configures XeLaTeX.
## Manual Pandoc Command
For fine-grained control, run pandoc directly:
```bash
pandoc input.md -o output.pdf \
--pdf-engine=xelatex \
-f markdown-smart \
-H header.tex \
-V mainfont="DejaVu Sans" \
-V monofont="DejaVu Sans Mono" \
-V geometry:margin=20mm \
-V fontsize=10pt \
-V colorlinks=true \
--highlight-style=tango \
--toc -V toc-title="Table of Contents"
```
Where `header.tex` contains:
```latex
\usepackage{xeCJK}
\setCJKmainfont{<CJK font name>}
```
## Key Details
- **Math**: Pandoc natively converts `$...$` (inline) and `$$...$$` (display) to LaTeX math. No MathJax/KaTeX needed.
- **CJK fonts**: Script auto-detects from: Noto Sans CJK SC > WenQuanYi Micro Hei > Droid Sans Fallback > AR PL UMing CN.
- **Emoji**: Replaced with text equivalents (`✅` → `[Y]`, `❌` → `[N]`, `⭐` → `*`) since most LaTeX fonts lack emoji glyphs.
- **Smart quotes**: Use `-f markdown-smart` to avoid curly quote rendering issues.
- **Long tables**: Pandoc may struggle with complex tables; keep tables simple or use `longtable` LaTeX package.
## Troubleshooting
| Problem | Fix |
|---------|-----|
| Missing character warnings | Check `fc-list :lang=zh` for available CJK fonts; install `fonts-noto-cjk` if needed |
| `xelatex not found` | Install `texlive-xetex` |
| PDF has no math rendering | Ensure markdown uses `$...$` / `$$...$$` (not HTML math tags) |
| Broken table layout | Simplify table or add `-V geometry:margin=15mm` for more width |
