A Parsing Expression Grammar (PEG) Parser generator DSL for Ruby

Hirb provides a mini view framework for console applications and uses it to improve ripl(irb)'s default inspect output. Given an object or array of objects, hirb renders a view based on the object's class and/or ancestry. Hirb offers reusable views in the form of helper classes. The two main help...

Routing tree web toolkit

Ancestry allows the records of a ActiveRecord model to be organized in a tree structure, using the materialized path pattern. It exposes the standard relations (ancestors, parent, root, children, siblings, descendants) and allows them to be fetched in a single query. Additional features i...

ParseTree is a C extension (using RubyInline) that extracts the parse tree for an entire class or a specific method and returns it as a s-expression (aka sexp) using ruby's arrays, strings, symbols, and integers. As an example: def conditional1(arg1) if arg1 == 0 then return 1 e...

RubyTree is a Ruby implementation of the generic tree data structure. It provides simple APIs to store named nodes, and to access, modify, and traverse the tree. The data model is node-centric, where nodes in the tree are the primary structural elements. It supports all comm...

A RBTree is a sorted associative collection that is implemented with a Red-Black Tree. It maps keys to values like a Hash, but maintains its elements in ascending key order. The interface is the almost identical to that of Hash.

Line-tree parses indented lines of text and returns an array representing a tree structure.

The Ruby Language Toolkit provides classes for creating context-free grammars, lexers, parsers, and abstract syntax trees.

A modular scale is a list of values that share the same relationship. These values are often used to size type and create a sense of harmony in a design. Proportions within modular scales are all around us from the spacing of the joints on our fingers to branches on trees. These natural proportio...
