Description : Recursive descent parsing library based on functional combinators.
Parser combinators are just higher-order functions that take parsers as
their arguments and return them as result values. Parser combinators are:
.
o First-class values
o Extremely composable
o Tend to make the code quite compact
o 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.
