Pry v0.3.1 is out!

[Dmitry Olshansky via Digitalmars-d-announce]

Pry is a new pragmatic parser combinators library.

(also available on Dub)

It's still in the early stages but I think it might be a good time to 
gauge some interest.

Two key areas of focus are (compared to say Pegged):
- performance, on par with hand-written code or die
- versatility, generating some goofy parse tree is not a goal, the goal 
is extraction of data the way the user specifies

For now it contains a modest example of a calculator app and a benchmark 
inspired by it. The interesting tidbit is that this version already 
includes an optimization that typically prevents recursive descent 
parser from falling into exponential behavior.

Future directions:
- actually add grammar layer on top of combinators, it is fancy but useful
- more built-in parsers to play with, including some stuff inspired by 
std.regex
- some goodies for usability, e.g. shortcuts to avoid constructing 
Stream out of string etc.
