Server-side hyphenation service


This plugin implements hyphenation for various languages. While there are client side javascript implementations - such as HyphenatorContrib - this one here hyhpenates texts on the server side. So why implement yet another hyphenation solution? Here's why.

Hyphenator.js has recently been abandoned and succeeded by yet another javascript package hyphenopoly. Those javascript packages keep changing all too often which is a pity sometimes. The api difference between hyphenator.js and hyphenopoly are so broad that it would require a rewrite of HyphenatorContrib anyway, besides a name change of the package. So implementing another extension was inevitable anyway. HyphenatorContrib still is working just fine. Still, all client side solutions suffer from an initial flicker of the text being reformatted after hyphens have been inserted. A text being hyphenated on the backend can be cached if required and does not suffer from flickering html pages being reformatted. That might be the reason why google never really followed up on CSS Text Module Level 3 with regards to hyphenation. It simply does not provide a smooth user experience & rendering performance.

HyphenationPlugin is based on TeX::Hyphen which uses TeX hyphenation patterns available for various languages.


Text might be hyphenated using the %HYPHENATE makro.

Parameter Description Default
"...", text="..." text to be hyphenated  
lang="..." language of the text to be hyphenated CONTENT_LANGUAGE, current user's language or system default
hyphen="..." character string to be used as as separator of sylables; try hyphe="-" to make hyphenation more visible ­
minlength="..." minimum length of a string to be hyphenated 5

Alternatively, you might define a hyphenation area by surrounding text with an HTML element of class hyphenate:

<div class="hyphenate" lang="..." data-hyphen="..." data-min-length="...">

The optional lang and data-hyphen attributes work as described above. Note that <div class="hyphenate"> ...</div> does not apply any additional css properties by default, such as justifying the text. This is up to the Foswiki skin, or any other css class assigned to the div element.

Within a hyphenation area <pre> ...</pre> elements are not hyphenated. You might explicitly protect a part of the hyphenate area from being processed by adding a donthyphenate class to an element:

<div class="hyphenate">
<pre>some code</pre>
<h2 class="donthyphenate">Don't hyphenate this heading</h2>

So text in the ... areas is hyphenated but not the <pre> or <h2> element.


%HYPHENATE{"Straßenbahnschienenritzenreiniger" lang="de" hyphen="-"}%

%HYPHENATE{"Incomprehensibilities" lang="en" hyphen="-"}%

Installation Instructions

You do not need to install anything in the browser to use this extension. The following instructions are for the administrator who installs the extension on the server.

Open configure, and open the "Extensions" section. "Extensions Operation and Maintenance" Tab -> "Install, Update or Remove extensions" Tab. Click the "Search for Extensions" button. Enter part of the extension name or description and press search. Select the desired extension(s) and click install. If an extension is already installed, it will not show up in the search results.

You can also install from the shell by running the extension installer as the web server user: (Be sure to run as the webserver user, not as root!)
cd /path/to/foswiki
perl tools/extension_installer <NameOfExtension> install

If you have any problems, or if the extension isn't available in configure, then you can still install manually from the command-line. See https://foswiki.org/Support/ManuallyInstallingExtensions for more help.
