Pyparsing Question

Hi all, I have a question on PyParsing. I am trying to create a parser for a hierarchical todo list format, but have hit a stumbling block. I have parsers for the header of the list (title and description), and the body (recursive descent on todo items). Individually they are working fine,

Re: Pyparsing Question.

Welcome to pyparsing! The simplest way to implement a markup processor in pyparsing is to define the grammar of the markup, attach a parse action to each markup type to convert the original markup to the actual results, and then use transformString to run through the input and do the

I have a home-grown Wiki that I created as an excercise, with it's own wiki markup (actually just a clone of the Trac wiki markup). The wiki text parser I wrote works nicely, but makes heavy use of regexes, tags and stacks to parse the text. As such it is a bit of a mantainability nightmare -
