Trying to Make Ruby's Parser Available as a Gem.

First, install Ruby master with Universal Parser.

RUBY_CONFIGURE_OPTS="cppflags=-DUNIVERSAL_PARSER" rbenv install ruby-dev

Clone this repository.

git clone https://github.com/S-H-GAMELINKS/refine_tree.git

Move refine_tree directory, and run bundle install.

cd refine_tree && bundle install

Finally, build RefineTree gem and install it.

bundle exec rake build
gem install pkg/refine_tree-0.1.0.gem

require 'refine_tree/refine_tree'

result = RefineTree.parse('117 + 117')

p result
# =>
#{
#  "NODE_SCOPE" => {
#    "args" => nil,
#    "body" => {
#      "NODE_OPCALL" => {
#        "recv" => {
#          "NODE_INTEGER" => 117
#        },
#        "mid" => :+,
#        "args" => {
#          "NODE_LIST" => [
#            {
#              "NODE_INTEGER"=>117
#            }
#          ]
#        }
#      }
#    }
#  }
#}

After checking out the repo, run bin/setup to install dependencies. You can also run bin/console for an interactive prompt that will allow you to experiment.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to rubygems.org.

Bug reports and pull requests are welcome on GitHub at https://github.com/S-H-GAMELINKS/refine_tree.
