NAME
HTML::WikiConverter - Convert HTML to wiki markup
SYNOPSIS
use HTML::WikiConverter;
my $wc = new HTML::WikiConverter( dialect => 'MediaWiki' );
print $wc->html2wiki( $html );
DESCRIPTION
HTML::WikiConverter
is an HTML to wiki converter. It can convert HTML source into a variety of wiki markups, called wiki "dialects". The following dialects are supported:
DokuWiki
Kwiki
MediaWiki
MoinMoin
Oddmuse
PhpWiki
PmWiki
SlipSlap
TikiWiki
UseMod
WakkaWiki
WikkaWiki
Note that while dialects usually produce satisfactory wiki markup, not all features of all dialects are supported. Consult individual dialects' documentation for details of supported features. Suggestions for improvements, especially in the form of patches, are very much appreciated.
METHODS
new
my $wc = new HTML::WikiConverter( dialect => $dialect, %attrs );
Returns a converter for the specified wiki dialect. Dies if $dialect
is not provided or its dialect module is not installed on your system. Attributes may be specified in %attrs
; see "ATTRIBUTES" for a list of recognized attributes.
html2wiki
$wiki = $wc->html2wiki( $html );
$wiki = $wc->html2wiki( html => $html );
$wiki = $wc->html2wiki( file => $file );
$wiki = $wc->html2wiki( file => $file, slurp => $slurp );
Converts HTML source to wiki markup for the current dialect. Accepts either an HTML string $html
or an HTML file $file
to read from.
You may optionally bypass HTML::Parser
's incremental parsing of HTML files (thus slurping the file in all at once) by giving $slurp
a true value.
parsed_html
my $html = $wc->parsed_html;
Returns HTML::TreeBuilder's string representation of the last-parsed syntax tree, showing how the input HTML was parsed internally. Useful for debugging.
available_dialects
my @dialects = HTML::WikiConverter->available_dialects;
Returns a list of all available dialects by searching the directories in @INC
for HTML::WikiConverter::
modules.
ATTRIBUTES
You may configure HTML::WikiConverter
using a number of attributes. These may be passed as arguments to the new
constructor, or can be called as object methods on a HTML::WikiConverter
object.
Some dialects allow other attributes in addition to those below. Consult individual dialect documentation for details.
dialect
(Required) Dialect to use for converting HTML into wiki markup. See the "DESCRIPTION" section above for a list of dialects. new
will fail if the dialect given is not installed on your system.
base_uri
URI to use for converting relative URIs to absolute ones. This effectively ensures that the src
and href
attributes of image and anchor tags, respectively, are absolute before converting the HTML to wiki markup, which is necessary for wiki dialects that handle internal and external links separately. Relative URLs are only converted to absolute ones if the base_uri
argument is present. Defaults to undef
.
wiki_uri
URI or a reference to a list of URIs used in determining which links are wiki links. This assumes that URLs to wiki pages are created by joining the wiki_uri
with the (possibly escaped) wiki page name. For example, the English Wikipedia might use
my $wc = new HTML::WikiConverter(
dialect => $dialect,
wiki_uri => [
'http://en.wikipedia.org/wiki/',
'http://en.wikipedia.org/w/index.php?action=edit&title='
]
);
Ward's wiki might use
my $wc = new HTML::WikiConverter(
dialect => $dialect,
wiki_uri => 'http://c2.com/cgi/wiki?'
);
The default is undef
, meaning that all links will be treated as external links.
See also the wiki_page_extractor
method, which provides a more flexible way of specifying how to extract page titles from URLs.
wiki_page_extractor
wiki_page_extractor
can be used instead of wiki_uri
, giving you a more flexible way to extract page titles from URLs.
The attribute takes a coderef that extracts a wiki page title from the given URL. If undef
(the default), the built-in extractor (which attempts to extract wiki page titles from URIs based on the value of the wiki_uri
attribute) will be used instead.
The extractor subroutine will be passed two arguments, the current HTML::WikiConverter object and a URI object. The return value should be the title of the wiki page extracted from the URI given. If no page title can be found or the URI does not refer to a wiki page, then the extractor should return undef
, which will fallback to the built-in extractor (which functions as mentioned previously).
wrap_in_html
Helps HTML::TreeBuilder
parse HTML fragments by wrapping HTML in <html>
and </html>
before passing it through html2wiki
. Boolean, enabled by default.
encoding
Specifies the encoding used by the HTML to be converted. Also determines the encoding of the wiki markup returned by the html2wiki
method. Defaults to 'utf8'
.
strip_comments
Removes HTML comments from the input before conversion to wiki markup. Boolean, enabled by default.
strip_head
Removes the HTML head
element from the input before converting. Boolean, enabled by default.
strip_scripts
Removes all HTML script
elements from the input before converting. Boolean, enabled by default.
ADDING A DIALECT
Consult HTML::WikiConverter::Dialects for documentation on how to write your own dialect module for HTML::WikiConverter
. Or if you're not up to the task, drop me an email and I'll have a go at it when I get a spare moment.
