ruby-whitequark-parser - 2.4.0.2-1 main

parser is a production-ready Ruby parser written in pure Ruby. It
recognizes as much or more code than Ripper, Melbourne, JRubyParser
or ruby_parser, and is vastly more convenient to use.
.
Among its keys features are: it provides precise source location
reporting, it has a documented AST format which is convenient to work
with, it parses 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4 and 2.5 syntax with
backwards-compatible AST formats and also parses MacRuby and
RubyMotion syntax extensions. It also has improved clang-like
diagnostic messages with location information.
.
Since it's written in pure Ruby, runs on MRI 1.8.7 or >=1.9.2, JRuby
and Rubinius, it has excellent test coverage and the source code is
readable and well commented.
.
Not to be confused with ruby_parser gem from Ryan Davis, of seattle.rb
Ruby user group.
