[ANN] parslet 1.1 - a PEG parser library

[Kaspar Schiess]

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.

Installation:

gem install parslet

Changes:

* For deep grammars, this release is several orders of magnitude
faster. Really! Benchmark at [2].
* Export to citrus and treetop dialects.
* You can apply visitors to the grammar now.
* Bug fixes and code cleanup.

Synopsis:

require 'parslet'
class Mini < Parslet:arser
ruleinteger) { match('[0-9]').repeat(1) }
rootinteger)
end

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

Please, ladies and gents, amuse yourselves!
