NamespaceHelper is a Ruby library providing a module with methods to ease namespace handling. For example getting the unprefixed name, the namespace parent or a list of namespace components of a class or module.

Contains resuable components extracted from the 18F Hub implementation for creating a team hub using Jekyll. See the 18F Public Hub for a running example: https://18f.gsa.gov/hub/ The 18F Hub repository is: https://github.com/18F/hub

Implements a gateway server to allow barebone basic sensor components to report state change updates as simple via TCP/UDP ports without the 'overhead' of the HTTP protocol. A power sensor for example might just broadcast a four byte floating point binary number once every second to an UDP port or an arduino board sends a UDP datagram whenever a button is pushed. You get the idea, this is how to bring embedded devices into the world of HTTP and Javascript...

chef-gen-flavor-base is a base class to make it easy to create 'flavors' for use with [chef-gen-flavors](https://github.com/jf647/chef-gen-flavors). chef-gen-flavors plugs into the 'chef generate' command provided by ChefDK to let you provide an alternate template for cookbooks and other chef components. This gem simply provides a class your flavor can derive from; templates are provided by separate gems, which you can host privately for use within your organization or publicly for the Chef community to use. An example flavor that demonstrates how to use this gem is distributed separately: [chef-gen-flavor-example](https://github.com/jf647/chef-gen-flavor-example) At present this is focused primarily on providing templates for generation of cookbooks, as this is where most organization-specific customization takes place. Support for the other artifacts that ChefDK can generate may work, but is not the focus of early releases.

Outbound sends automated email, SMS, phone calls and push notifications based on the actions users take or do not take in your app. The Outbound API has two components: Identify each of your users and their attributes using an identify API call. Track the actions that each user takes in your app using a track API call. Because every message is associated with a user (identify call) and a specific trigger action that a user took or should take (track call), Outbound is able to keep track of how each message affects user actions in your app. These calls also allow you to target campaigns and customize each message based on user data. Example: When a user in San Francisco(user attribute) does signup(event) but does not upload a picture(event) within 2 weeks, send them an email about how they'll benefit from uploading a picture.

== Terminal UIs, the Ruby Way RatatuiRuby[https://rubygems.org/gems/ratatui_ruby] is a RubyGem built on Ratatui[https://ratatui.rs], a leading TUI library written in Rust[https://rust-lang.org]. You get native performance with the joy of Ruby. gem install ratatui_ruby {rdoc-image:https://ratatui-ruby.dev/hero.gif}[https://www.ratatui-ruby.dev/docs/v0.10/examples/app_cli_rich_moments/README_md.html] === Rich Moments Add a spinner, a progress bar, or an inline menu to your CLI script. No full-screen takeover. Your terminal history stays intact. ==== Inline Viewports Standard TUIs erase themselves on exit. Your carefully formatted CLI output disappears. Users lose their scrollback. <b>Inline viewports</b> solve this. They occupy a fixed number of lines, render rich UI, then leave the output in place when done. Perfect for spinners, menus, progress indicators—any brief moment of richness. require "ratatui_ruby" RatatuiRuby.run(viewport: :inline, height: 1) do |tui| until connected? status = tui.paragraph(text: "\#{spin} Connecting...") tui.draw { |frame| frame.render_widget(status, frame.area) } end end === Build Something Real Full-screen applications with {keyboard and mouse input}[https://www.ratatui-ruby.dev/docs/v0.10/examples/app_all_events/README_md.html]. The managed loop sets up the terminal and restores it on exit, even after crashes. RatatuiRuby.run do |tui| loop do tui.draw do |frame| frame.render_widget( tui.paragraph(text: "Hello, RatatuiRuby!", alignment: :center), frame.area ) end case tui.poll_event in { type: :key, code: "q" } then break else nil end end end ==== Widgets included: [Layout] {Block}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_block/README_md.html], {Center}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_center/README_md.html], {Clear (Popup, Modal)}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_popup/README_md.html], {Layout (Split, Grid)}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_layout_split/README_md.html], {Overlay}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_overlay/README_md.html] [Data] {Bar Chart}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_barchart/README_md.html], {Chart}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_chart/README_md.html], {Gauge}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_gauge/README_md.html], {Line Gauge}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_line_gauge/README_md.html], {Sparkline}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_sparkline/README_md.html], {Table}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_table/README_md.html] [Text] {Cell}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_cell/README_md.html], {List}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_list/README_md.html], {Rich Text (Line, Span)}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_rich_text/README_md.html], {Scrollbar (Scroll)}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_scrollbar/README_md.html], {Tabs}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_tabs/README_md.html] [Graphics] {Calendar}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_calendar/README_md.html], {Canvas}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_canvas/README_md.html], {Map (World Map)}[https://www.ratatui-ruby.dev/docs/v0.10/examples/widget_map/README_md.html] Need something else? {Build custom widgets}[https://www.ratatui-ruby.dev/docs/v0.10/doc/concepts/custom_widgets_md.html] in Ruby! --- === Testing Built In TUI testing is tedious. You need a headless terminal, event injection, snapshot comparisons, and style assertions. RatatuiRuby bundles all of it. require "ratatui_ruby/test_helper" class TestColorPicker < Minitest::Test include RatatuiRuby::TestHelper def test_swatch_widget with_test_terminal(10, 3) do RatatuiRuby.draw do |frame| frame.render_widget(Swatch.new(:red), frame.area) end assert_cell_style 2, 1, char: "█", bg: :red end end end ==== What's inside: - <b>Headless terminal</b> — No real TTY needed - <b>Snapshots</b> — Plain text and rich (ANSI colors) - <b>Event injection</b> — Keys, mouse, paste, resize - <b>Style assertions</b> — Color, bold, underline at any cell - <b>Test doubles</b> — Mock frames and stub rects - <b>UPDATE_SNAPSHOTS=1</b> — Regenerate baselines in one command --- ==== Inline Menu Example require "ratatui_ruby" # This example renders an inline menu. Arrow keys select, enter confirms. # The menu appears in-place, preserving scrollback. When the user chooses, # the TUI closes and the script continues with the selected value. class RadioMenu CHOICES = ["Production", "Staging", "Development"] # ASCII strings are universally supported. PREFIXES = { active: "●", inactive: "○" } # Some terminals may not support Unicode. CONTROLS = "↑/↓: Select | Enter: Choose | Ctrl+C: Cancel" # Let users know what keys you handle. TITLES = ["Select Environment", # The default title position is top left. { content: CONTROLS, # Multiple titles can save space. position: :bottom, # Titles go on the top or bottom, alignment: :right }] # aligned left, right, or center def call # This method blocks until a choice is made. RatatuiRuby.run(viewport: :inline, height: 5) do |tui| # RatauiRuby.run manages the terminal. @tui = tui # The TUI instance is safe to store. show_menu until chosen? # You can use any loop keyword you like. end # `run` won't return until your block does, RadioMenu::CHOICES[@choice] # so you can use it synchronously. end # Classes like RadioMenu are convenient for private # CLI authors to offer "rich moments." def show_menu = @tui.draw do |frame| # RatatuiRuby gives you low-level access. widget = @tui.paragraph( # But the TUI facade makes it easy to use. text: menu_items, # Text can be spans, lines, or paragraphs. block: @tui.block(borders: :all, titles: TITLES) # Blocks give you boxes and titles, and hold ) # one or more widgets. We only use one here, frame.render_widget(widget, frame.area) # but "area" lets you compose sub-views. end def chosen? # You are responsible for handling input. interaction = @tui.poll_event # Every frame, you receive an event object: return choose if interaction.enter? # Key, Mouse, Resize, Paste, FocusGained, # FocusLost, or None objects. They come with move_by(-1) if interaction.up? # predicates, support pattern matching, and move_by(1) if interaction.down? # can be inspected for properties directly. quit! if interaction.ctrl_c? # Your application must handle every input, false # even interrupts and other exit patterns. end def choose # Here, the loop is about to exit, and the prepare_next_line # block will return. The inline viewport @choice # will be torn down and the terminal will end # be restored, but you are responsible for # positioning the cursor. def prepare_next_line # To ensure the next output is on a new area = @tui.viewport_area # line, query the viewport area and move RatatuiRuby.cursor_position = [0, area.y + area.height] # the cursor to the start of the last line. puts # Then print a newline. end def quit! # All of your familiar Ruby control flow prepare_next_line # keywords work as expected, so we can exit 0 # use them to leave the TUI. end def move_by(line_count) # You are in full control of your UX, so @choice = (@choice + line_count) % CHOICES.size # you can implement any logic you need: end # Would you "wrap around" here, or not? # def menu_items = CHOICES.map.with_index do |choice, i| # Notably, RatatuiRuby has no concept of "\#{prefix_for(i)} \#{choice}" # "menus" or "radio buttons". You are in end # full control, but it also means you must def prefix_for(choice_index) # implement the logic yourself. For larger return PREFIXES[:active] if choice_index == @choice # applications, consider using Rooibos, PREFIXES[:inactive] # an MVU framework built with RatatuiRuby. end # Or, use the upcoming ratatui-ruby-kit, # our object-oriented component library. def initialize = @choice = 0 # However, those are both optional, and end # designed for full-screen Terminal UIs. # RatatuiRuby will always give you the most choice = RadioMenu.new.call # control, and is enough for "rich CLI puts "You chose \#{choice}!" # moments" like this one. --- === Full App Solutions RatatuiRuby renders. For complex applications, add a framework that manages state and composition. ==== Rooibos[https://www.rooibos.run] (Framework) Model-View-Update architecture. Inspired by Elm, Bubble Tea, and React + Redux. Your UI is a pure function of state. - Functional programming with MVU - Commands work off the main thread - Messages, not callbacks, drive updates ==== {Kit}[https://sr.ht/~kerrick/ratatui_ruby/#chapter-3-the-object-path--kit] (Coming Soon) Component-based architecture. Encapsulate state, input handling, and rendering in reusable pieces. - OOP with stateful components - Separate UI state from domain logic - Built-in focus management & click handling Both use the same widget library and rendering engine. Pick the paradigm that fits your brain. --- === Why RatatuiRuby? Ruby deserves world-class terminal user interfaces. TUI developers deserve a world-class language. RatatuiRuby wraps Rust's Ratatui via native extension. The Rust library handles rendering. Your Ruby code handles design. >>> "Text UIs are seeing a renaissance with many new TUI libraries popping up. The Ratatui bindings have proven to be full featured and stable." — {Mike Perham}[https://www.mikeperham.com/], creator of Sidekiq[https://sidekiq.org/] and Faktory[https://contribsys.com/faktory/] ==== Why Rust? Why Ruby? Rust excels at low-level rendering. Ruby excels at expressing domain logic and UI. RatatuiRuby puts each language where it performs best. ==== Versus CharmRuby CharmRuby[https://charm-ruby.dev/] wraps Charm's Go libraries. Both projects give Ruby developers TUI options. [Integration] CharmRuby: Two runtimes, one process. RatatuiRuby: Native extension in Rust. [Runtime] CharmRuby: Go + Ruby (competing). RatatuiRuby: Ruby (Rust has no runtime). [Memory] CharmRuby: Two uncoordinated GCs. RatatuiRuby: One Garbage Collector. [Style] CharmRuby: The Elm Architecture (TEA). RatatuiRuby: TEA, OOP, or Imperative. --- === Links [Get Started] {Quickstart}[https://www.ratatui-ruby.dev/docs/v0.10/doc/getting_started/quickstart_md.html], {Examples}[https://www.ratatui-ruby.dev/docs/v0.10/examples/app_cli_rich_moments/README_md.html], {API Reference}[https://www.ratatui-ruby.dev/docs/v0.10/], {Guides}[https://www.ratatui-ruby.dev/docs/v0.10/doc/index_md.html] [Ecosystem] Rooibos[https://www.rooibos.run], {Kit}[https://sr.ht/~kerrick/ratatui_ruby/#chapter-3-the-object-path--kit] (Planned), {Framework}[https://sr.ht/~kerrick/ratatui_ruby/#chapter-5-the-framework] (Planned), {UI Widgets}[https://sr.ht/~kerrick/ratatui_ruby/#chapter-6-licensing] (Planned) [Community] {Forum}[https://forum.setdef.com/c/ratatui-ruby/6], {Announcements}[https://forum.setdef.com/tags/c/ratatui-ruby/6/announcement], {Discussion}[https://forum.setdef.com/tags/c/ratatui-ruby/6/discussion], {Bug Tracker}[https://forum.setdef.com/tags/c/ratatui-ruby/6/bug] [Contribute] {Contributing Guide}[https://man.sr.ht/~kerrick/ratatui_ruby/contributing.md], {Code of Conduct}[https://man.sr.ht/~kerrick/ratatui_ruby/code_of_conduct.md], {Project History}[https://man.sr.ht/~kerrick/ratatui_ruby/history/index.md], {Pull Requests}[https://forum.setdef.com/tags/c/ratatui-ruby/6/patch] --- [Website] https://www.ratatui-ruby.dev [Source] https://github.com/setdef/RatatuiRuby [RubyGems] https://rubygems.org/gems/ratatui_ruby [Upstream] https://ratatui.rs [Build Status] https://builds.sr.ht/~kerrick/ratatui_ruby © 2026 Kerrick Long · Library: LGPL-3.0-or-later · Website: CC-BY-NC-ND-4.0 · Snippets: MIT-0

In computer science, a disjoint-set data structure, also called a union–find data structure or merge–find set, is a data structure that keeps track of a set of elements partitioned into a number of disjoint (non-overlapping) subsets. It provides near-constant-time operations (bounded by the inverse Ackermann function) to add new sets, to merge existing sets, and to determine whether elements are in the same set. In addition to many other uses (see the Applications section), disjoint-sets play a key role in Kruskal's algorithm for finding the minimum spanning tree of a graph. A disjoint-set forest consists of a number of elements each of which stores an id, a parent pointer, and, in efficient algorithms, a value called the "rank". The parent pointers of elements are arranged to form one or more trees, each representing a set. If an element's parent pointer points to no other element, then the element is the root of a tree and is the representative member of its set. A set may consist of only a single element. However, if the element has a parent, the element is part of whatever set is identified by following the chain of parents upwards until a representative element (one without a parent) is reached at the root of the tree. Forests can be represented compactly in memory as arrays in which parents are indicated by their array index. Disjoint-set data structures model the partitioning of a set, for example to keep track of the connected components of an undirected graph. This model can then be used to determine whether two vertices belong to the same component, or whether adding an edge between them would result in a cycle. The Union–Find algorithm is used in high-performance implementations of unification. This data structure is used by the Boost Graph Library to implement its Incremental Connected Components functionality. It is also a key component in implementing Kruskal's algorithm to find the minimum spanning tree of a graph. Note that the implementation as disjoint-set forests doesn't allow the deletion of edges, even without path compression or the rank heuristic. Sharir and Agarwal report connections between the worst-case behavior of disjoint-sets and the length of Davenport–Schinzel sequences, a combinatorial structure from computational geometry.
