Hitsuji is a library that implements a tree data structure, where each node is represented by a value, points to other values, or performs a function on some values. When the tree is updated, the inputs to the functions will change, hence changing the outputs, eventually propagating the update through the entire tree. Data structures can also be exported to disk, allowing for wide applications of this software, e.g. handling big data, managing content, etc.

Run Ruby blocks inside their own process.

A Hyperloop application consists of isomorphic React Components, Active Record Models, Stores, Operations and Policiespec. Test them all from Rspec, regardless if the code runs on the client or server.

ViewModels provide a means of encapsulating a collection of related data and specifying its JSON serialization.

It traces the execution path of a program and displays the source code of each method call in the callgraph

Helps you avoid common pitfalls when dealing with app config

Documentation DSL that provides method level comments and links or imports to other comments. Comments can be written in MarkDown format and the current method can be transformed from Ruby code into a MarkDown readable format. Static instance, class methods, and constants can be called and used inside of ERB tags. All defined areas are generated into markdown file per class.

Adds several instance methods to the core Method class so methods can tell you more about themselves.

fine grained code reloading

Ruby doesn't like you arbitrarily deciding when to execute expressions. Take control with this gem. It's a simple way to mix in additional behavior into Proc that will allow you to make custom DSL's that will change how ruby deals with expressions.
