HyperTeX¶

HyperTeX is HyperTeX 2.0, a web document format that uses LaTeX syntax instead of HTML, together with a browser for reading it.

It started from a question: what if the web's hypertext language had been TeX rather than HTML in the 1990s? Scientists already think and write in LaTeX. HyperTeX aims to let those documents open like web pages and link to one another, instead of being frozen into PDFs.

What it does¶

Reads .htex documents: equation numbers, cross-references, theorem environments, collapsible proofs and step-by-step derivations, exactly as written.
Opens existing .tex files: keep the extension and they load in compatibility mode.
Links documents together: through htex:// addresses and ordinary web URLs.
Draws figures: a subset of TikZ and pgfplots rendered as SVG.
Makes parameters interactive: values declared with \parameter become sliders, and equations and plots follow them.
Handles Hangul in math: Korean letters in formulas are treated like Greek letters and set in a sans-serif face.
Works in ordinary browsers too: convert documents to HTML with MathML, or build them into a static website.

Unknown commands are skipped¶

When HyperTeX meets a command it cannot handle, it does not stop. It leaves that command out and shows the rest of the document. If macro expansion exceeds its limit, a red error marker appears in place.

Components¶

Component	What it does
Parser	Turns `.htex` and `.tex` sources into a document tree
HTML renderer	Renders the tree as HTML with MathML
Figure renderer	Converts TikZ and pgfplots figures to SVG
Viewer	A desktop browser with tabs and an address bar (PySide6)
Web server	Serves documents to ordinary browsers

The parser, renderer and server use only the Python standard library.

Specification¶

The format is defined in the repository.
