Why? Because its original purpose was to convert Brat's parser (in Ruby) to Brat. But (besides that being silly) things have gone a different direction now and so I doubt much more will happen with this code.
This is a very simplistic translator which converts (some subset of) Ruby code to Brat code.
gem build ruby2brat.gemspec
gem install ruby2brat*.gem
ruby2brat
will read in Ruby code from stdin and spit back Brat code on stdout. Piping it in works well:
cat test.rb | ruby2brat > test.brat
From the base directory:
ruby test/test.rb
