Use any HTML template as a theme generator for your Rails app. Installs an HTML template, and its CSS, JavaScript and image assets into your Rails app, ready to go in an instant. You just tell it which DOM elements are special, e.g. where to put the <%= yield %>, load your app in the browser and see the theme in action.

autotest is a continous testing facility meant to be used during development. As soon as you save a file, autotest will run the corresponding dependent tests. minitest-autotest is the latest incarnation of the venerable and wise autotest. This time, it talks to minitest via minitest-server. As a result, there is no output parsing. There are no regexps to tweak. There's no cruft or overhead. == Features/Problems: * Continually and intelligently test only those files you change with autotest.

natspec - natural specification (comments) parser / machinery; document application binary interfaces (abis) for Ethereum & Co. (blockchain) contracts

RinRuby is a Ruby library that integrates the R interpreter in Ruby, making R's statistical routines and graphics available within Ruby. The library consists of a single Ruby script that is simple to install and does not require any special compilation or installation of R. Since the library is 100% pure Ruby, it works on a variety of operating systems, Ruby implementations, and versions of R. RinRuby's methods are simple, making for readable code. The {website [rinruby.ddahl.org]}[http://rinruby.ddahl.org] describes RinRuby usage, provides comprehensive documentation, gives several examples, and discusses RinRuby's implementation.
