NAME

HTML::Hyphenate - class for inserting soft hyphens into HTML.

VERSION

This is version 0.04.

SYNOPSIS

    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->output_xml(1);
    $hyphenator->default_lang('en-us');
    $hyphenator->default_included(1);
    $hyphenator->classes_included(['shy']);
    $hyphenator->classes_excluded(['noshy']);

DESCRIPTION

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.

SUBROUTINES/METHODS

HTML::Hyphenate->new()

Constructs a new HTML::Hyphenate object.

$hyphenator->hyphenated()

Returns the HTML including the soft hyphens.

$hyphenator->html();

Gets or sets the HTML to hyphenate.

$hyphenator->style();

Gets or sets the style to use for pattern usages in TeX::Hyphen. Can be czech or german.

$hyphenator->min_length();

Gets or sets the minimum word length required for having soft hyphens inserted. Defaults to 10 characters.

$hyphenator->min_pre(2);

Gets or sets the minimum amount of characters in a word preserved before the first soft hyphen. Defaults to 2 characters.

$hyphenator->min_post(2);

Gets or sets the minimum amount of characters in a word preserved after the last soft hyphen. Defaults to 2 characters.

$hyphenator->output_xml(1);

Have HTML::TreeBuilder output HTML in HTML or XML modus.

$hyphenator->default_lang('en-us');

Gets or sets the default pattern to use when no language can be derived from the HTML.

$hyphenator->default_included();

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.

$hyphenator->classes_included();

Gets or sets an arrayref of class names that will have soft hyphens inserted.

$hyphenator->classes_excluded();

Gets or sets an arrayref of class names that will not have soft hyphens inserted.

DEPENDENCIES

INCOMPATIBILITIES

    This module has the same limits as TeX::Hyphen, TeX::Hyphen::Pattern and HTML::TreeBuilder.

DIAGNOSTICS

This module uses Log::Log4perl for logging.

  • It warns when a language encountered in the HTML is not supported by TeX::Hyphen::Pattern

BUGS AND LIMITATIONS

  • Empty subclass test fails, this is probably a Class::Meta::Express issue. The empty subclass can't be empty, it needs at least:

    use Class::Meta::Express;

class {
	ctor 'new';
};

  • 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 "cafeetje" should be hyphenated as "cafe-tje" and not "cafee-tje" and "buurtje" can be hyphenated as "buur-tje" or "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 hyphenation patterns provide.

  • The round trip from HTML source via HTML::Tree to HTML source might introduce changes to the source, for example accented characters might be transformed to HTML encoded entity equivalent.

CONFIGURATION AND ENVIRONMENT

The output is generated by HTML::TreeBuilder and can be either HTML or XML.
