internal package Foswiki::Plugins::WysiwygPlugin::TML2HTML

Convertor class for translating TML (Topic Meta Language) into HTML

The convertor does not use the Foswiki rendering, as that is a lossy conversion, and would make symmetric translation back to TML an impossibility.

The design goal was to support round-trip conversion from well-formed TML to XHTML1.0 and back to identical TML. Notes that some deprecated TML syntax is not supported.

ClassMethod new()

Construct a new TML to HTML convertor.

ObjectMethod convert( $tml, \%options ) → $tml

Convert a block of TML text into HTML. Options:

• getViewUrl is a reference to a method:
  getViewUrl($web,$topic) -> $url (where $topic may include an anchor)
• expandVarsInURL is a reference to a static method:
  expandVarsInURL($url, \%options) -> $url
  that expands selected variables in URLs so that, for example, tags appear as pictures in the wysiwyg editor.
• xmltag is a reference to a hash. The keys are names of XML-like tags. The values are references to a function to determine if the content of the tag must be protected:
  fn($markup) -> $bool
  The $markup appears between the delimiters. The functions may modify the markup.
• dieOnError makes convert throw an exception if a conversion fails. The default behaviour is to encode the whole topic as verbatim text.
