unified-latex-builder

What is this?

Functions to help build a unified-latex Abstract Syntax Tree (AST) with hyperscript-like syntax.

When should I use this?

If you want to programmatically create Ast.Node nodes.

Install

npm install @unified-latex/unified-latex-builder

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

arg(args, special)

Create an Argument. special.braces can optionally specify the signature of the open/close marks that each argument uses. For example

arg("a", { braces: "[]" });

will result in arguments [a]. Valid braces are *, [, {, <, and (.

null may be passed as the value of an empty optional argument. If null is passed, the openBrace and closeBrace of the argument will be set to empty strings and the contents will be set to an empty array. For example,

args([null, "b"], { braces: "[]{}" });

will produce the same structure as if the the first "optional argument" were omitted in regular parsing.

function arg(
  args: CoercibleArgument | Ast.Node[],
  special: ArgumentSpecialOptions
): Ast.Argument;

Parameters

| Param | Type | | :------ | :-------------------------------- | | args | Omitted | | special | ArgumentSpecialOptions |

where

type ArgumentSpecialOptions = {
  braces?: string;
  openMark?: string;
  closeMark?: string;
};

args(args, special)

Create an Argument list. special.braces can optionally specify the signature of the open/close marks that each argument uses. For example

args(["a", "b"], { braces: "[]{}" });

will result in arguments [a]{b}. Valid braces are *, [, {, (, and <.

null may be passed as the value of an empty optional argument. If null is passed, the openBrace and closeBrace of the argument will be set to empty strings and the contents will be set to an empty array. For example,

args([null, "b"], { braces: "[]{}" });

will produce the same structure as if the the first "optional argument" were omitted in regular parsing.

function args(
  args: CoercibleArgument | CoercibleArgument[],
  special: ArgumentsSpecialOptions
): Ast.Argument[];

Parameters

| Param | Type | | :------ | :-------------------------------- | | args | Omitted | | special | ArgumentsSpecialOptions |

where

type ArgumentsSpecialOptions = {
  braces?: string;
  defaultOpenMark?: string;
  defaultCloseMark?: string;
};

env(name, body, envArgs, special)

Create an Environment node.

function env(
  name: String,
  body: CoercibleNode | CoercibleNode[],
  envArgs: CoercibleArgument | CoercibleArgument[],
  special: {}
): Ast.Environment;

Parameters

| Param | Type | | :------ | :-------------------------------- | | name | String | | body | Omitted | | envArgs | Omitted | | special | {} |

m(name, marcoArgs, special)

Create a Macro with the given name. The macro may be followed by any number of arguments.

function m(
  name: String,
  marcoArgs: CoercibleArgument | CoercibleArgument[],
  special: MacroSpecialOptions
): Ast.Macro;

Parameters

| Param | Type | | :-------- | :-------------------------------- | | name | String | | marcoArgs | Omitted | | special | MacroSpecialOptions |

where

type MacroSpecialOptions = {
  escapeToken?: string;
};

s(value)

Create a String node from value

function s(value: string | Ast.String): Ast.String;

Parameters

| Param | Type | | :---- | :--------------------- | | value | string \| Ast.String |

Constants

| Name | Type | Description | | :--- | :--------------- | :--------------- | | SP | Ast.Whitespace | Whitespace node. |
