class TaskJuggler::RichTextScanner
The RichTextScanner
is used by the RichTextParser
to chop the input text into digestable tokens. It specializes the TextScanner class for RichText
syntax. The scanner can operate in various modes. The current mode is context dependent. The following modes are supported:
:bop : at the begining of a paragraph. :bol : at the begining of a line. :inline : in the middle of a line :nowiki : ignoring all MediaWiki special tokens :html : read anything until </html> :ref : inside of a REF [[ .. ]] :href : inside of an HREF [ .. ] :func : inside of a block <[ .. ]> or inline <- .. -> function
