- Add a new port: devel/py-funcparserlib

Browse source 
Parser combinators are just higher-order functions that take parsers as
  their arguments and return them as result values. Parser combinators are:

   * First-class values
   * Extremely composable
   * Tend to make the code quite compact
   * Resemble the readable notation of xBNF grammars

  Parsers made with funcparserlib are pure-Python LL(*) parsers. It means that
  it's very easy to write them without thinking about look-aheads and all that
  hardcore parsing stuff. But the recursive descent parsing is a rather slow
  method compared to LL(k) or LR(k) algorithms.

  So the primary domain for funcparserlib is parsing little languages or external
  DSLs (domain specific languages).

  The library itself is very small. Its source code is only 0.5 KLOC, with lots
  of comments included. It features the longest parsed prefix error reporting,
  as well as a tiny lexer generator for token position tracking.
