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 include named scopes, integrity checking, integrity restoration, arrangement of (sub)tree into hashes and different strategies for dealing with orphaned records.

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 helpers, Hirb::Helpers::Table and Hirb::Helpers::Tree, provide several options for generating ascii tables and trees. Using Hirb::Helpers::AutoTable, hirb has useful default views for at least ten popular database gems i.e. Rails' ActiveRecord::Base. Other than views, hirb offers a smart pager and a console menu. The smart pager only pages when the output exceeds the current screen size. The menu is used in conjunction with tables to offer two dimensional menus.

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.

(This gem was named as treevisitor) tree.rb is a 'clone' of tree unix command. The gem implements a library to mange tree structures. The gem contains also a library to build tree with a dsl (domain specific language), and an implementation of visitor design pattern. An example of DSL to build tree: <pre> tree = TreeNode.create do node "root" do leaf "l1" node "sub" do leaf "l3" end node "wo leaves" end </pre>

Ruby wrapper around the escodegen JavaScript generator that generates ECMA script from an abstract syntax tree.

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 common tree-traversal methods (pre-order, post-order, and breadth first). RubyTree mixes in the Enumerable and Comparable modules and behaves like a standard Ruby collection (iteration, comparison, etc.). RubyTree also includes a binary tree implementation, which provides in-order node traversal besides the other methods. RubyTree can import from and export to JSON, and supports Ruby’s object marshaling.

Treequel-Shell is a collection of LDAP tools based on the Treequel LDAP toolkit. It includes: treequel :: an LDAP shell/editor; treat your LDAP directory like a filesystem! treewhat :: an LDAP schema explorer. Dump objectClasses and attribute type info in several convenient formats.

Tool that allows to generate Objective-C and Swift dependency tree from object files For usages examples run: objc_dependency_tree_generator -h

This package contains a simple wrapper for the TreeTagger, a POS tagger based on decision trees and developed by Helmut Schmid at IMS in Stuttgart, Germany. You should have the TreeTagger with all library files installed on your machine in order to use this wrapper.

With treeoid, you can create tree-style hierarchies for Mongoid classes. Just "include Treeoid" and you're ready to roll. You get a "parent" accessor, a "children" array, plus a scope called "hierarchically" that spits everything out in hierarchical order - perfect for front end rendering.

Gem renamed to tree.rb (https://rubygems.org/gems/tree.rb). Please update your dependencies. Implementation of visitor design pattern. It contains a 'tree.rb' command line clone of the tree unix tool.
