[ANN] parslet 1.3.0 released

parslet is a Parsing Expression Grammar based[1] parser generator 
library. Uff. Now that is out of our system, here goes what it really 
does: It makes writing parsers pleasant for the rest of us. No code 
generation, clear access to data, unit testable.

* https://github.com/kschiess/parslet

Installation:

gem install parslet

Changes:

* A better behaved context object for the variable-syntax in transform
   blocks. It now behaves like any Ruby object with instance variables
   and attribute readers.
* An experimental micro-VM based implementation of the parsing engine
   to get around limitations of Ruby 1.9.3 fibers. (stack size)
* Several small bugs and gotchas in relation to other libraries are
   now fixed.

Synopsis:

   require 'parslet'
   class Mini < Parslet::Parser
     rule(:integer) { match('[0-9]').repeat(1) }
     root(:integer)
   end

   Mini.new.parse("132432") # => 132432

'parsing. for when you need it.'
