import { 
function load(options?: GukhanmunOptions): Promise<Gukhanmun>

Creates a Gukhanmun converter with the given options.

Initialises the WASM module on the first call (subsequent calls reuse the cached module). Dictionaries supplied via GukhanmunOptions.dictionaries are fetched and passed to the Rust engine as FileDictionarySource values.

Note: unlike the Rust ko-kr preset, the JavaScript preset never includes a bundled dictionary. Pass dictionaries: [await stdictFst()] to include the Standard Korean Language Dictionary.

Ordered list of dictionary sources. Sources are queried in order; earlier entries take precedence. When omitted (or empty), only the fallback Unihan character map is used (no stdict).

var console: Console

The console module provides a simple debugging console that is similar to the JavaScript console mechanism provided by web browsers.

The module exports two specific components:

  • A Console class with methods such as console.log(), console.error() and console.warn() that can be used to write to any Node.js stream.
  • A global console instance configured to write to process.stdout and process.stderr. The global console can be used without importing the node:console module.

Warning: The global console object's methods are neither consistently synchronous like the browser APIs they resemble, nor are they consistently asynchronous like all other Node.js streams. See the note on process I/O for more information.

Example using the global console:

console.log('hello world');
// Prints: hello world, to stdout
console.log('hello %s', 'world');
// Prints: hello world, to stdout
console.error(new Error('Whoops, something bad happened'));
// Prints error message and stack trace to stderr:
//   Error: Whoops, something bad happened
//     at [eval]:5:15
//     at Script.runInThisContext (node:vm:132:18)
//     at Object.runInThisContext (node:vm:309:38)
//     at node:internal/process/execution:77:19
//     at [eval]-wrapper:6:22
//     at evalScript (node:internal/process/execution:76:60)
//     at node:internal/main/eval_string:23:3

const name = 'Will Robinson';
console.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to stderr

Example using the Console class:

const out = getStreamSomehow();
const err = getStreamSomehow();
const myConsole = new console.Console(out, err);

myConsole.log('hello world');
// Prints: hello world, to out
myConsole.log('hello %s', 'world');
// Prints: hello world, to out
myConsole.error(new Error('Whoops, something bad happened'));
// Prints: [Error: Whoops, something bad happened], to err

const name = 'Will Robinson';
myConsole.warn(`Danger ${name}! Danger!`);
// Prints: Danger Will Robinson! Danger!, to err
@seesource
console
.
Console.log(message?: any, ...optionalParams: any[]): void (+1 overload)

Prints to stdout with newline. Multiple arguments can be passed, with the first used as the primary message and all additional used as substitution values similar to printf(3) (the arguments are all passed to util.format()).

const count = 5;
console.log('count: %d', count);
// Prints: count: 5, to stdout
console.log('count:', count);
// Prints: count: 5, to stdout

Gukhanmun.convert(source: string, format?: Format): string

Converts source to hangul in one shot. Buffers the entire input before returning.

@paramsource - The text to convert.@paramformat - Input / output format. Defaults to "text".@returnsThe converted text.@throws{@linkGukhanmunError } on conversion failure.
convert
("<p>漢字</p>", "html"));
// → <p>한자</p>

Gukhanmun parses the input as an HTML fragment, converts hanja in text nodes, and serialises the result while preserving all tags and attributes.

Elements that are always preserved

These elements and their descendants are never modified:

  • <code>, <kbd>, <pre>, <samp>
  • <script>, <style>, <textarea>
  • Elements with translate="no"
  • <ruby> annotation content

Preserving elements by CSS class

Use html.preserveClasses to skip conversion inside elements that carry specific classes:

const 
const g: Gukhanmun
g

function load(options?: GukhanmunOptions): Promise<Gukhanmun>

Creates a Gukhanmun converter with the given options.

@seeHtmlOptions
html
: {
HtmlOptions.preserveAttributes?: readonly (string | {

    readonly value?: string;
})[] | undefined

Attribute matchers; an element is preserved when it carries a matching attribute. Each entry is either:

  • A bare string — preserve any element that has the attribute, regardless of value (e.g. "data-no-translate").
  • An object { name, value? } — preserve elements where the attribute equals value, or has the attribute when value is omitted.

Equivalent to --html-preserve-attr KEY[=VALUE] on the CLI.

preserveAttributes

"data-no-hanja", // any element with this attribute {
name: string
name

value?: string | undefined

Ruby markup in HTML

Combine "html" format with a ruby rendering mode:
