=head1 NAME

jscreole - Parse Creole into DOM

=head1 SYNOPSIS

var creole = new creole({ interwiki: { MeatballWiki: 'http://www.usemod.com/cgi-bin/mb.pl?', TiddlyWiki: 'http://www.tiddlywiki.com/#', WikiCreole: 'http://www.wikicreole.org/wiki/', Palindrome: function(link) { return 'http://www.example.com/wiki/' + link.split('').reverse().join(''); } }, linkFormat: '#' });

var div = document.createElement('div'); creole.parse(div, "* This is [Wikipedia:Wikitext|wikitext]");

=head1 DESCRIPTION

This module implements Creole 1.0 parser, as defined by Lhttp://www.wikicreole.org/wiki/Creole1.0.

=head2 Options

=over

=item defaultImageText

Alternative text for an image with no alternative text

{{image.png}}

as opposed to empty alternative text

{{image.png|}}

Note that strict Creole 1.0 doesn't allow images with no alternative text.

=item interwiki

Interwiki map. Object properties' values are strings, arrays of one or two strings, or functions. The first string is a leading part of the URL. If the second string is given as well, it is a trailing part. If the value is a function, which takes a link identifier as an argument, its return value is the whole URL.

=item linkFormat

Internal links' format. Same format as in L<"interwiki">'s properties.

=item strict

Whether the parser is strict Creole 1.0. For constructor only, i. e. non-overridable in C method. A non-strict parser allows images in tables and images with no alternative text.

=head1 NAME

creole._base - Parse text into DOM

=head1 SYNOPSIS

// Define grammar var g = { para: { _tag: 'p', _regex: /( \t\S.+((\r?\n|\r) \t\S.))/, _capture: 0 } }; g._root = { _children: g.para };

// Create parser var parser = new creole._base(g);

// Parse var div = document.createElement('div'); parser.parse(div, 'para\n' + ' continues\n\n' + 'another para\n \n' + 'yet another para');

=head1 DESCRIPTION

This module implements a simple recursive descent parser using regular expressions for lexical analysis. The result is stored into a DOM object, that can be then put in a document or traversed using standard DOM API.

=head2 Parser

=over

=item new creole._base(grammar, options)

The constructor creates a new parser object given a grammar and options. The grammar is an object of any type, which must contain a root property, that also must be an object of any type. The root is cast to a type specified by C<this._ruleConstructor>, being C<creole._rule> by default. See L<"Rules"> for more info on defining rule objects.

Options are optional but if passed it must be an object. The only option available in C<creole._base> is C, which should be set C for Microsoft Internet Explorer compatibility. Derived objects and subinterfaces may extend the C object with their own options.

=item parse(node, data, options)

This method parses flat text data and creates a DOM tree inside a given node, which should be a Node object. If options are passed, they override those passed to the constructor. Options merge at the first depth, merging nested options is not supported.

=back

=head2 Rules

=over

=item _regex

A regular expression to match the input.

=item _capture

What should be captured for the output data: 0 for the whole matched substring, 1 and so on for corresponding capturing brackets. If not listed, data will be empty.

=item _replaceRegex

=item _replaceString

If set, captured data will be processed before output.

=item _tag

If set, captured data will be enclosed inside a new child element, otherwise they will be put in the current node.

=item _attrs

If set to an object, a new child element will have the given attributes.

=item _children

An array of grammar rules, which define possible child nodes.

=item _fallback

If there are chunks which don't match any child rule, they are being processed with this one.
