hyphen

Demo page

This is a text hyphenation library, based on Franklin M. Liang's hyphenation algorithm. In core of the algorithm lies a set of hyphenation patterns. They are extracted from hand-hyphenated dictionaries. Patterns for this library were taken from ctan.org and ported to Javascript.

import { hyphenate } from "hyphen/en";

hyphenate("A certain king had a beautiful garden").then(result => {
  // A cer[-]tain king had a beau[-]ti[-]ful garden
  // [-] is soft hyphen
});

Install

npm install hyphen

or

yarn add hyphen

Usage

import {
  hyphenate,
  hyphenateHTML,
  hyphenateHTMLSync,
  hyphenateSync
} from "hyphen/en";

hyphenate("Plain text - hyphenate everything").then(result => {
  // Plain text - hy[-]phen[-]ate every[-]thing
});

hyphenateHTML("<blockquote>HTML tags are NOT hyphenated</blockquote>").then(
  result => {
    // <blockquote>HTML tags are NOT hy[-]phen[-]at[-]ed</blockquote>
  }
);

hyphenateHTMLSync("<blockquote>Sync version of `hyphenateHTML`</blockquote>");
// <blockquote>Sync ver[-]sion of `hy[-]phen[-]ate[-]HTML`</blockquote>

hyphenateSync("Sync version of `hyphenate`");
// Sync ver[-]sion of `hy[-]phen[-]ate`

Factory function

import createHyphenator from "hyphen";
import patterns from "hyphen/patterns/en-us";

const hyphenate = createHyphenator(patterns, { async: true });
const hyphenateHTML = createHyphenator(patterns, { async: true, html: true });
const hyphenateHTMLSync = createHyphenator(patterns, { html: true });
const hyphenateSync = createHyphenator(patterns);

Note: This original factory function surves mostly for the backwards compatibility reasons.

Text hyphenation in CSS

The CSS hyphens property is intended to add hyphenation support to modern browsers without Javascript:

p {
  hyphens: auto;
}

It is part of the CSS Text Level 3 specification. The browser compatibility list can be found on the related MDN page.
