HTML::Hyphenate - insert soft hyphens into HTML
This document describes HTML::Hyphenate version
use HTML::Hyphenate; $hyphenator = new HTML::Hyphenate(); $html_with_soft_hyphens = $hyphenator->hyphenated($html); $hyphenator->html($html); $hyphenator->style($style); # czech or german $hyphenator->min_length(10); $hyphenator->min_pre(2); $hyphenator->min_post(2); $hyphenator->default_lang('en-us'); $hyphenator->default_included(1); $hyphenator->classes_included(['shy']); $hyphenator->classes_excluded(['noshy']);
Most HTML rendering engines used in web browsers don't figure out by themselves how to hyphenate words when needed, but we can tell them how they might do it by inserting soft hyphens into the words.
Constructs a new HTML::Hyphenate object.
Returns the HTML including the soft hyphens.
Gets or sets the HTML to hyphenate.
Gets or sets the style to use for pattern usages in TeX::Hyphen. Can be
Gets or sets the minimum word length required for having soft hyphens inserted. Defaults to 10 characters.
Gets or sets the minimum amount of characters in a word preserved before the first soft hyphen. Defaults to 2 characters.
Gets or sets the minimum amount of characters in a word preserved after the last soft hyphen. Defaults to 2 characters.
Gets or sets the default pattern to use when no language can be derived from the HTML.
Gets or sets if soft hyphens should be included in the whole tree by default. This can be used to insert soft hyphens only in parts of the HTML having specific class names.
Gets or sets a reference to an array of class names that will have soft hyphens inserted.
Gets or sets a reference to an array of class names that will not have soft hyphens inserted.
Registers a TeX::Hyphen object to handle the language defined by
The output is generated by Mojo::DOM so the environment variable
MOJO_DOM_CSS_DEBUG can be set to debug it's CSS selection process.
This module has the same limits as TeX::Hyphen, TeX::Hyphen::Pattern and Mojo::DOM. Tests might fail if the patterns used for them are updated and change the test result.
This module uses Log::Log4perl for logging when it's resurrected.
It warns when a language encountered in the HTML is not supported by TeX::Hyphen::Pattern
Perfect hyphenation can be more complicated than just inserting a hyphen somewhere in a word, and sometimes requires semantics to get it right. For example
cafeetjeshould be hyphenated as
buurtjecan be hyphenated as
buurt-je, depending on it's meaning. While HTML could provide a bit more context - mainly the language being used - than plain text to handle these issues, the initial purpose of this module is to make it possible for HTML rendering engines that support soft hyphens to be able to break long words over multiple lines to avoid unwanted overflow.
The hyphenation doesn't get better than TeX::Hyphenate and it's hyphenation patterns provide.
The round trip from HTML source via Mojo::DOM to HTML source might introduce changes to the source, for example accented characters might be transformed to HTML encoded entity equivalents or Boolean attributes are converted to a different notation.
