Using this package, you can do powerful pattern recognition easily from your shell command line using a simple suite of tools. Applications include music cateogrization, text classification, handwritten digit recognition, and evolutionary tree reconstruction. The technique is based on a very ge...

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...

A screen + vim IDE setup for editing a Rails tree

Provides a generic tree data structure with ability to store keyed node elements in the tree. The implementation mixes in the Enumerable module.

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...

Rockit is a potent parser generator and gives you AST's (Abstract Syntax Tree's) which you can pattern match and pretty-print. Rockit does not distinghuish between lexing and parsing so the generated parsers are scanner-/lexer-less. The vision is to extend Rockit with more advanced compiler-relat...

This module implements ordered n-ary branching tree structures. It includes support for breadth- and depth- first iteration, and serialization to and from a bracketed tree string.

This is the original commit of the rtags source code as written by Keiju ISHITSUKA as part of the irb project. Now irb has moved into the main Ruby source tree rtags has become an independent project

ID3-based implementation of the M.L. Decision Tree algorithm

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

== FEATURES/PROBLEMS: Chirp is a DSL for manipulating file systems. In the same way that rake is aimed at making system buildig easy, chirp is designed to make doing things to entire file systems easy. Chirp is still very much in development and you should be very careful with it: since chirp ...

CommandSet is a user interface framework. Its focus is a DSL for defining commands, much like Rake or RSpec. A default readline based terminal interpreter (complete with context sensitive tab completion, and the amenities of readline: history editing, etc) is included. It could very well be ad...

A plugin for DataMapper that allows model objects to be a part of a heirarchal tree structure. Based on the acts_as_tree plugin for ActiveRecord.

== DESCRIPTION: Charlie is a library for genetic algorithms (GA) and genetic programming (GP). == FEATURES: - Quickly develop GAs by combining several parts (genotype, selection, crossover, mutation) provided by the library. - Sensible defaults are provided with any genotype, so often you only n...

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.
