NAME

Text::MetaMarkup - Simple structured POD/Wiki-ish markup

SYNOPSIS

    use Text::MetaMarkup::HTML;
    print Text::MetaMarkup::HTML->new->parse(file => $filename);

DESCRIPTION

MetaMarkup was inspired by POD, Wiki and PerlMonks. I created it because I wanted a simple format to write documents for my site quickly.

A document consists of paragraphs. Paragraphs are separated by blank lines, which may contain whitespace. A paragraph can be prefixed with tag:, which should correspond to an HTML block level tag like h1, p or pre.

Paragraphs cannot be nested. Paragraphs that start with # are ignored.

In a paragraph, inline tags are used with curly braces. That is: {i:foo} is <i>foo</i> in HTML.

Inline tags can be nested.

Characters can be escaped using a backslash character. Never are escaped characters special: \n is n in the result, not a newline.

Links are written as [url|text]. Inline tags can be used in the text part.

SUBCLASSING

Do not use Text::MetaMarkup directly. It is intended to be subclassed. Most people will just use Text::MetaMarkup::HTML, but you can create your own.

Packages in Text::MetaMarkup::AddOn:: are special. They don't subclass Text::MetaMarkup but used by subclasses (using @ISA (use base)) to provide additional tags.

Text::MetaMarkup::HTML::JuerdNL is used by my own homepage and is included in the distribution as an example.

METHODS

Provided by Text::MetaMarkup

new

Constructor method. Takes a list of key/value pairs which is used to fill the hash that gets blessed. These values are currently not used, but could be used by the subclasses.

parse

Takes two arguments. Either file and a filename, fh and a filehandle or string and a string. Returns the converted document.

parse_document

Takes one argument: a string of paragraphs. Returns the converted document.

parse_paragraph

Takes one argument: a string of text, possibly with inline tags. Returns the converted paragraph.

parse_link

Takes one argument: The link (without square brackets). Returns the converted link.

text

Takes one argument: Plain text. Unescapes the text and returns it.

To be provided by a subclass

escape

Takes one argument: text. Should return the escaped version of that text.

paragraph

Takes two arguments: tag and text. Should return the converted form.

inline

Takes two arguments: tag and text. Should return the converted form.

link

Takes two arguments: a hashref and text. The hashref contains href, scheme and rest. Should return the converted form.

If the link provided is [http://juerd.nl/|Juerd's homepage], then link gets in @_: { href => 'http://juerd.nl/', scheme => 'http', rest => '//juerd.nl/' }, 'Juerd\'s homepage'.

Special methods

If paragraph tag foo is encountered, paragraph_foo is tried before paragraph. If inline tag foo is encountered, inline_foo is tried before inline. If link scheme foo is encountered, link_foo is tried before link. If the tag or scheme specific method exists, the general one is not called.

Furthermore, a subclass can implement any of start_document, end_document, start_paragraph and end_paragraph. Parapgraph start/end handlers get the tag as their only argument. The value returned by any of these methods is used in the result document.

A subclass should try to format paragraphs that start with * as bulleted lists.
