@unified-latex/unified-latex-util-split v1.8.0

unified-latex-util-split

What is this?

Functions to manipulate unified-latex Abstract Syntax Tree (AST).

When should I use this?

If you want break apart or join an array of nodes based on a condition. For example, this is used to split on & characters in the align environment.

Install

npm install @unified-latex/unified-latex-util-split

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.

Functions

arrayJoin(array, sep)

Joins an array of arrays with the item sep

function arrayJoin<T>(array: T[][], sep: T | T[]): T[];

Parameters

splitOnCondition(nodes, splitFunc, options)

Split a list of nodes based on whether splitFunc returns true. If onlySplitOnFirstOccurrence is set to true in the options object, then there will be at most two segments returned.

function splitOnCondition(
  nodes: Ast.Node[],
  splitFunc: (node: Ast.Node) => boolean,
  options: { onlySplitOnFirstOccurrence?: boolean }
): { segments: Ast.Node[][]; separators: Ast.Node[] };

Parameters

splitOnMacro(ast, macroName)

Split an array of AST nodes based on a macro. An object {segments: [], macros: []} is returned. The original array is reconstructed as segments[0] + macros[0] + segments[1] + ....

function splitOnMacro(
  ast: Ast.Node[],
  macroName: string | string[]
): { segments: Ast.Node[][]; macros: Ast.Macro[] };

Parameters

`unsplitOnMacro({ segments, macros,

})`

Does the reverse of splitOnMacro

function unsplitOnMacro({
  segments,
  macros,
}: {
  segments: Ast.Node[][];
  macros: Ast.Node[] | Ast.Node[][];
}): Ast.Node[];
