line_parse

Performs substitutions on lines called by fragment_slurp, at least. Calls image_markup(), textile_process(), markdown_process().

Returns string.

Parses some special markup, specifically:

<textile></textile> - Text::Textile to HTML
<markdown></markdown> - Text::Markdown::Discount to HTML
<freeverse></freeverse>
<retcon></retcon>
<list></list>

<image>filename.ext
optional alt tag
optional title text</image>

${variable} interpolation from the WRT object
<perl>print "hello world";</perl>
<include>path/to/file/from/project/root</include>

eval_perl

Evaluate embedded Perl in a string, replacing blocks enclosed with <perl> tags with whatever they return (well, evaluated in a scalar context). Returns the modified string.

Also handles simple ${variables}, replacing them from the keys to $self.

include_process

Inline replace <include>filename</include> tags, replacing them with the contents of files.

retrieve_include

Get the contents of an included file. This probably needs a great deal more thought than I am presently giving it.

textile_process

Inline replace <textile> markup in a string.

markdown_process

Inline replace <markdown> markup in a string.

image_markup

Parse out an image tag and return the appropriate html.

Relies on image_size from App::WRT::Image.
