siefkenjunified-latex-types
What is this?
Types for the unified-latex Abstract Syntax Tree (AST). These types extend the unist AST,
but instead of a children attribute, they have a content attribute.
When should I use this?
If you're working with unified-latex ASTs.
Install
npm install @unified-latex/unified-latex-types
This package contains both esm and commonjs exports. To explicitly access the esm export,
import the .js file. To explicitly access the commonjs export, import the .cjs file.

* the input array, removing any nodes that are part of the macro's argument.
*
* This function will only be called on a macro if it has no existing `args`.
*
* Note: for stability when printing/accessing a node's arguments, this function
* should always return an argument array of the same length, regardless of
* whether optional arguments are present. For example, if this function parses
* a node with signature `o m`, it should ways return a length-two array of arguments.
* A "blank" argument (one that does not show up during printing) can be created
* with `args([], { openMark: "", closeMark: "" })`, using the `unified-latex-builder` package.
