A TeX-style document engine for Scala.

Why texish

texish lays out and renders documents the way TeX does. You write in a small TeX-like language — macros, math mode, boxes and glue — and the engine breaks paragraphs into lines and lines into pages, then draws them through a pluggable backend.

\section{Introduction}
It is well known that $E = mc^2$. The displayed form,
$$ \int_0^\infty e^{-x^2}\,dx = \frac{\sqrt\pi}{2}, $$
follows from the Gaussian integral.

Body text is set in Latin Modern Roman, math in the matching Latin Modern Math through an OpenType MATH table, and monospaced text in Latin Modern Mono — one coherent family across prose, equations, and code.

What’s here

• Getting Started — install texish and render your first document.
• Guide — the document format, text and markup, mathematics, figures and images, the inline vector-graphics mode, chemistry, and data plotting.
• Reference — the command-line tool and a command cheat sheet.

What it does

• Knuth-Plass line breaking with Liang hyphenation, cost-based page breaks with widow/orphan control, and balanced multi-column layout, all in a point-space coordinate system.
• TeX math mode — inline $…$ and centered display $$…$$: fractions, radicals, scripts, stretchy delimiters, accents, big operators, matrices, the math alphabets (\mathbf, \mathbb, \mathfrak, …), and phantom/\smash spacing.
• A document format (\use{document}) — title blocks, numbered sections, cross-references and a table of contents, lists, quotations, figures and tables with captions, and footnotes.
• Clickable links and images — \href/\url become real PDF link annotations; \includegraphics places PNG and JPEG images.
• Vector graphics — \picture draws shapes, paths, and placed type inline, through the same pipeline as the text.
• Chemistry and plotting — \use{chem} sets reaction equations and structures; \use{plot} draws line, scatter, bar, and function plots with labelled axes.
• Railroad diagrams — \use{railroad} turns a W3C-style EBNF grammar into a railroad (syntax) diagram, one picture per rule.
• Node-and-edge diagrams — \use{diagram} places named, measured nodes in nine shapes and routes labelled arrows between them; \use{flowchart}, \use{automaton} and \use{er} add program-flowchart, state-machine and entity-relationship vocabularies on top.
• Two platforms — the JVM (Graphics2D raster) and Scala Native (Cairo PDF + image).
• Nothing to install — the core faces and the base/document packages are compiled into the artifact, so the dependency alone renders an ordinary document: Latin, Greek, Cyrillic, mathematics, highlighted source code. No font tree, no environment variable.
