node.js module

The Hyphenopoly-package contains a file called hyphenopoly.module.js. This module provides hyphenation for node.js applications.

Install

npm install hyphenopoly

Usage

One language:

const Hyphenopoly = require("hyphenopoly");

const textHyphenators = Hyphenopoly.config({
    "require": ["en-us"],
    "hyphen": "•"
});

textHyphenators.then(
    function ff(hyphenateText) {
        console.log(hyphenateText("Hyphenation enhances justification."));
    }
).catch(
    function err(e) {
        console.log(e);
    }
);

More then one language:

const Hyphenopoly = require("hyphenopoly");

const textHyphenators = Hyphenopoly.config({
    "require": ["de", "en-us"],
    "hyphen": "•"
});

textHyphenators.get("de").then(
    function ff(hyphenateText) {
        console.log(hyphenateText("Silbentrennung verbessert den Blocksatz."));
    }
);

textHyphenators.get("en-us").then(
    function ff(hyphenateText) {
        console.log(hyphenateText("Hyphenation enhances justification."));
    }
);

Synchronous mode

By default, Hyphenopoly.config returns a promise (or a Map of promises). Some code bases are not yet capable of handling async code. By setting "sync" : true the hyphenopoly module switches to a sync mode.

const hyphenopoly = require("hyphenopoly");

const hyphenator = hyphenopoly.config({
    "sync": true,
    "require": ["de", "en-us"],
    "hyphen": "•",
    "exceptions": {
        "en-us": "en-han-ces"
    }
});

const hy1 = hyphenator.get("en-us")("hyphenation enhances justification.");
const hy2 = hyphenator.get("de")("Silbentrennung verbessert den Blocksatz.");


console.log(hy1);
console.log(hy2);

Configuration

The .config-method takes an object as argument:

Defaults:

{
    "compound": "hyphen",
    "exceptions": {},
    "hyphen": String.fromCharCode(173),
    "leftmin": 0,
    "loader": "fs",
    "minWordLength": 6,
    "normalize": false,
    "orphanControl": 1,
    "paths": {
        "maindir": `${__dirname}/`,
        "patterndir": `${__dirname}/patterns/
    },
    "require": [],
    "rightmin": 0,
    "sync": false
}

The only option that Must be set is require which takes an array of language-tags.

loader

By default hyphenopoly.module.js loads pattern files and hyphenEnginge by using nodes "fs"-module. This can be changed to the "http"-module by setting the loader to "http":

const hyphenator = hyphenopoly.config({
    "require": […],
    "loader": "http"
});

This is useful if the module is transformed to a script used in a webbrowser (e.g. by using browserify).

other options

For documentation about the other options see the Hyphenopoly.js-documentation:

Supported languages (since Version 2.8.0)

A list of supported languages can be programmatically obtained by looking at Hyphenopoly.supportedLanguages:

const Hyphenopoly = require("hyphenopoly");
Hyphenopoly.supportedLanguages.includes("en-us"); //true
Hyphenopoly.supportedLanguages.includes("en"); //false

Performance

On my machine with node.js 10.0.1:

module	setup	hyphenate 100 de words
hyphenopoly	12ms	2ms
hyphen	40ms	370ms
hypher	70ms	3ms
