MoonBit Typographical Compiler: Architecture & Features

Slide 1: Introduction to moon-typst

moon-typst brings modern typographical typesetting to the MoonBit ecosystem.

Zero-FFI Pure MoonBit: 100% portable across Native, JS, and WebAssembly targets
Composable Pipeline: Separate MoonBit modules handle parsing, layout, and rendering
Multi-Target Rendering: Seamless output to SVG, semantic HTML5, and standard PDF 1.4
Rich Mathematical Layout: First-class support for fractions, square roots, matrices, and limits

Slide 2: Mathematical Capabilities

Typesetting complex scientific formulas with pixel-perfect alignment:

fracalpha + beta , gamma + delta

Multivariate transformations with matrix layouts:

100010001

State vectors in 3D projection:

u v w

Slide 3: Architectural Pipeline

The internal pipeline consists of four modular packages:

core: Abstract syntax tree, color representations, and length unit conversions
diag: Source span tracking, diagnostic error collection, and colorized terminal reports
eval: Lexical scoping, variable environments, and cascading style rules
parser: Fast recursive descent lexer and token stream analyzer
layout: Spatial bounding box calculations, text measurement, and table layout
render: SVG vector emitter, HTML5 document generator, and PDF 1.4 binary serializer

Slide 4: Getting Started

Compile any Typst document directly using the CLI:

# Render to vector SVG
typst-render presentation.typ -o presentation.svg

# Render to standard PDF 1.4
typst-render presentation.typ -p -o presentation.pdf

# Render to semantic HTML5
typst-render presentation.typ --html -o presentation.html
