TextExpress (txp)

TextExpress (txp) is a little framework for building custom text processors (such as Markdown to HTML).

A processor is made up of a parser and multiple BlockHandlers. The parser typically processes line-by-line and will do the following on each line:

find a handler that accepts the beginning of the line
if no eligible handler found, throw error
otherwise, process line
- handler can consume entire line. if it will process the next line potentially, it returns accept, otherwise, it returns complete
if handler returned accept, on the next line, it can then either reject (resulting in looking up a handler), accept, or complete

This process repeats until all the lines are consumed without error.
