NAME

Text::MultiMarkdown - Convert MultiMarkdown syntax to (X)HTML

SYNOPSIS

use Text::MultiMarkdown 'markdown';
my $html = markdown($text);

use Text::MultiMarkdown 'markdown';
my $html = markdown( $text, {
    empty_element_suffix => '>',
    tab_width => 2,
    use_wikilinks => 1,
} );

use Text::MultiMarkdown;
my $m = Text::MultiMarkdown->new;
my $html = $m->markdown($text);

use Text::MultiMarkdown;
my $m = Text::MultiMarkdown->new(
    empty_element_suffix => '>',
    tab_width => 2,
    use_wikilinks => 1,
);
my $html = $m->markdown( $text );

DESCRIPTION

Markdown is a text-to-HTML filter; it translates an easy-to-read / easy-to-write structured text format into HTML. Markdown's text format is most similar to that of plain text email, and supports features such as headers, *emphasis*, code blocks, blockquotes, and links.

Markdown's syntax is designed not as a generic markup language, but specifically to serve as a front-end to (X)HTML. You can use span-level HTML tags anywhere in a Markdown document, and you can use block level HTML tags (<div>, <table> etc.). Note that by default Markdown isn't interpreted in HTML block-level elements, unless you add a markdown=1" attribute to the element. See Text::Markdown for details.

This module implements the MultiMarkdown markdown syntax extensions from:

http://fletcherpenney.net/multimarkdown/

SYNTAX

For more information about (original) Markdown's syntax, see:

http://daringfireball.net/projects/markdown/

This module implements MultiMarkdown, which is an extension to Markdown..

The extension is documented at:

http://fletcherpenney.net/multimarkdown/

and borrows from php-markdown, which lives at:

http://michelf.com/projects/php-markdown/extra/

This documentation is going to be moved/copied into this module for clearer reading in a future release..

OPTIONS

MultiMarkdown supports a number of options to it's processor which control the behaviour of the output document.

These options can be supplied to the constructor, on in a hash with the individual calls to the markdown method. See the synopsis for examples of both of the above styles.

The options for the processor are:

use_metadata

Controls the metadata options below.

strip_metadata

If true, any metadata in the input document is removed from the output document (note - does not take effect in complete document format).

empty element suffix

This option can be used to generate normal HTML output. By default, it is ' />', which is xHTML, change to '>' for normal HTML.

img_ids

Controls if <img> tags generated have an id attribute. Defaults to true. Turn off for compatibility with the original markdown.

heading_ids

Controls if <hX> tags generated have an id attribute. Defaults to true. Turn off for compatibility with the original markdown.

bibliography_title

The title of the generated bibliography, defaults to 'Bibliography'.

tab_width

Controls indent width in the generated markup, defaults to 4

disable_tables

If true, this disables the MultiMarkdown table handling.

disable_footnotes

If true, this disables the MultiMarkdown footnotes handling.

disable_bibliography

If true, this disables the MultiMarkdown bibliography/citation handling.

disable_definition_lists

If true, this disables the MultiMarkdown definition list handling.

A number of possible items of metadata can also be supplied as options. Note that if the use_metadata is true then the metadata in the document will overwrite the settings on command line.

Metadata options supported are:

document_format
base_url
self_url - The document url is prepended to the "#" anchor of footnotes.

METADATA

MultiMarkdown supports the concept of 'metadata', which allows you to specify a number of formatting options within the document itself. Metadata should be placed in the top few lines of a file, on value per line as colon separated key/value pairs. The metadata should be separated from the document with a blank line.

Most metadata keys are also supported as options to the constructor, or options to the markdown method itself. (Note, as metadata, keys contain space, whereas options the keys are underscore separated.)

You can attach arbitrary metadata to a document, which is output in HTML <META> tags if unknown, see t/11document_format.t for more info.

A list of 'known' metadata keys, and their effects are listed below:

document format

If set to 'complete', MultiMarkdown will render an entire xHTML page, otherwise it will render a document fragment

css

Sets a CSS file for the file, if in 'complete' document format.

title

Sets the page title, if in 'complete' document format.

If set to '1' or 'on', causes links that are WikiWords to automatically be processed into links.

base url

This is the base URL for referencing wiki pages. In this is not supplied, all wiki links are relative.

METHODS

new

A simple constructor, see the SYNTAX and OPTIONS sections for more information.

markdown

The main function as far as the outside world is concerned. See the SYNOPSIS for details on use.
