Typst currently doesn’t have reflection natively (using typst code to look at other typst code in a structured way).

But, Typst supports plugins compiled to WebAssembly. And Typst itself is written in Rust, a language that can compile to WebAssembly.

“So,” the devil whispers in your ear, “why not compile a part of typst itself to a plugin and run it inside typst?” [The Inception soundtrack plays…]

Yes, it is very inefficient. Wasteful, even. But it works, and that is what counts.

API

This package exposes three functions:

• parse-flat(str): Produce a basic representation of typst syntax
• parse-markup(str): Produce a rich representation of typst markup (like the contents of a .typ file)
• operator-info(str): Get arity, precedence and associativity information for an operator.
