== Confidently Build Terminal Apps Rooibos[https://rooibos.run] helps you build interactive terminal applications. Keep your code understandable and testable as it scales. Rooibos handles keyboard, mouse, and async work so you can focus on behavior and user experience. gem install rooibos <i>Currently in beta. APIs may change before 1.0.</i> === Get Started in Seconds rooibos new my_app cd my_app rooibos run That's it. You have a working app with keyboard navigation, mouse support, and clickable buttons. Open <tt>lib/my_app.rb</tt> to make it your own. --- === The Pattern \Rooibos uses Model-View-Update, the architecture behind Elm[https://guide.elm-lang.org/architecture/], Redux[https://redux.js.org/], and {Bubble Tea}[https://github.com/charmbracelet/bubbletea]. State lives in one place. Updates flow in one direction. The runtime handles rendering and runs background work for you. --- === Hello, MVU The simplest \Rooibos app. Press any key to increment the counter. Press <tt>Ctrl</tt>+<tt>C</tt> to quit. require "rooibos" module Counter # Init: How do you create the initial model? Init = -> { 0 } # View: What does the user see? View = -> (model, tui) { tui.paragraph(text: <<~END) } Current count: #{model}. Press any key to increment. Press Ctrl+C to quit. END # Update: What happens when things change? Update = -> (message, model) { if message.ctrl_c? Rooibos::Command.exit elsif message.key? model + 1 end } end Rooibos.run(Counter) That's the whole pattern: Model holds state, Init creates it, View renders it, and Update changes it. The runtime handles everything else. --- === Your First Real Application A file browser in sixty lines. It opens files, navigates directories, handles errors, styles directories and hidden files differently, and supports vim-style keyboard shortcuts. If you can do this much with this little code, imagine how easy _your_ app will be to build. require "rooibos" module FileBrowser # Model: What state does your app need? Model = Data.define(:path, :entries, :selected, :error) Init = -> { path = Dir.pwd entries = Entries[path] Ractor.make_shareable( # Ensures thread safety Model.new(path:, entries:, selected: entries.first, error: nil)) } View = -> (model, tui) { tui.block( titles: [model.error || model.path, { content: KEYS, position: :bottom, alignment: :right}], borders: [:all], border_style: if model.error then tui.style(fg: :red) else nil end, children: [tui.list(items: model.entries.map(&ListItem[model, tui]), selected_index: model.entries.index(model.selected), highlight_symbol: "", highlight_style: tui.style(modifiers: [:reversed]))] ) } Update = -> (message, model) { return model.with(error: ERROR) if message.error? model = model.with(error: nil) if model.error && message.key? if message.ctrl_c? || message.q? then Rooibos::Command.exit elsif message.home? || message.g? then model.with(selected: model.entries.first) elsif message.end? || message.G? then model.with(selected: model.entries.last) elsif message.up_arrow? || message.k? then Select[:-, model] elsif message.down_arrow? || message.j? then Select[:+, model] elsif message.enter? then Open[model] elsif message.escape? then Navigate[File.dirname(model.path), model] end } private # Lines below this are implementation details KEYS = "↑/↓/Home/End: Select | Enter: Open | Esc: Navigate Up | q: Quit" ERROR = "Sorry, opening the selected file failed." ListItem = -> (model, tui) { -> (name) { modifiers = name.start_with?(".") ? [:dim] : [] fg = :blue if name.end_with?("/") tui.list_item(content: name, style: tui.style(fg:, modifiers:)) } } Select = -> (operator, model) { new_index = model.entries.index(model.selected).public_send(operator, 1) model.with(selected: model.entries[new_index.clamp(0, model.entries.length - 1)]) } Open = -> (model) { full = File.join(model.path, model.selected.delete_suffix("/")) model.selected.end_with?("/") ? Navigate[full, model] : Rooibos::Command.open(full) } Navigate = -> (path, model) { entries = Entries[path] model.with(path:, entries:, selected: entries.first, error: nil) } Entries = -> (path) { Dir.children(path).map { |name| File.directory?(File.join(path, name)) ? "#{name}/" : name }.sort_by { |name| [name.end_with?("/") ? 0 : 1, name.downcase] } } end Rooibos.run(FileBrowser) --- === Batteries Included ==== Commands Applications fetch data, run shell commands, and set timers. \Rooibos Commands run off the main thread and send results back as messages. <b>HTTP requests:</b> Update = -> (message, model) { case message in :fetch_users [model.with(loading: true), Rooibos::Command.http(:get, "/api/users", :got_users)] in { type: :http, envelope: :got_users, status: 200, body: } model.with(loading: false, users: JSON.parse(body)) in { type: :http, envelope: :got_users, status: } model.with(error: "HTTP #{status}") end } <b>Shell commands:</b> Update = -> (message, model) { case message in :list_files Rooibos::Command.system("ls -la", :listed_files) in { type: :system, envelope: :listed_files, stdout:, status: 0 } model.with(files: stdout.lines.map(&:chomp)) in { type: :system, envelope: :listed_files, stderr:, status: } model.with(error: stderr) end } <b>Timers:</b> Update = -> (message, model) { case message in { type: :timer, envelope: :tick, elapsed: } [model.with(frame: model.frame + 1), Rooibos::Command.wait(1.0 / 24, :tick)] end } <b>And more!</b> \Rooibos includes <tt>all</tt>, <tt>batch</tt>, <tt>bubble</tt>, <tt>cancel</tt>, <tt>custom</tt>, <tt>deliver</tt>, <tt>exit</tt>, <tt>http</tt>, <tt>map</tt>, <tt>open</tt>, <tt>system</tt>, <tt>tick</tt>, and <tt>wait</tt> commands. You can also define your own custom commands for complex orchestration. Every command produces a message, and Update handles it the same way. ==== Testing \Rooibos makes TUIs so easy to test, you'll save more time by writing tests than by not testing. <b>Unit test Update, View, and Init.</b> No terminal needed. Test helpers included. def test_moves_selection_down_with_j model = Ractor.make_shareable(FileBrowser::Model.new( path: "/", entries: %w[bin exe lib], selected: "bin", error: nil)) message = RatatuiRuby::Event::Key.new(code: "j") result = FileBrowser::Update.call(message, model) assert_equal "exe", result.selected end <b>Style assertions.</b> Draw to a headless terminal, verify colors and modifiers. def test_directories_are_blue with_test_terminal(60, 10) do model = Ractor.make_shareable(FileBrowser::Model.new( path: "/", entries: %w[file.txt subdir/], selected: "file.txt", error: nil)) widget = FileBrowser::View.call(model, RatatuiRuby::TUI.new) RatatuiRuby.draw { |frame| frame.render_widget(widget, frame.area) } assert_blue(1, 2) # "subdir/" at column 1, row 2 end end <b>System tests.</b> Inject events, run the full app, snapshot the result. def test_selection_moves_down with_test_terminal(120, 30) do Dir.mktmpdir do |dir| FileUtils.touch(File.join(dir, "a")) FileUtils.touch(File.join(dir, "b")) FileUtils.touch(File.join(dir, "c")) inject_key(:down) inject_key(:ctrl_c) # Tests use explicit params to inject deterministic initial state. Rooibos.run( model: Ractor.make_shareable(FileBrowser::Model.new( path: dir, entries: %w[a b c], selected: "a", error: nil)), view: FileBrowser::View, update: FileBrowser::Update ) assert_snapshots("selection_moved_down") do |lines| title = "┌/tmp/test#{'─' * 107}┐" lines.map do |l| l.gsub(/┌#{Regexp.escape(dir)}[^┐]*┐/, title) end end end end end Snapshots record both plain text and ANSI colors. Normalization blocks mask dynamic content (timestamps, temp paths) for cross-platform reproducibility. Run <tt>UPDATE_SNAPSHOTS=1 rake test</tt> to regenerate baselines. ==== Scale Up Large applications decompose into fragments. Each fragment has its own Model, View, Update, and Init. Parents compose children. The pattern scales. The Router DSL eliminates boilerplate: module Dashboard include Rooibos::Router route :stats, to: StatsPanel route :network, to: NetworkPanel receive_events :ctrl_c, -> { Rooibos::Command.exit } only when: -> (_message, model) { !model.modal_open } do receive_events :q, -> { Rooibos::Command.exit } forward_events :s, to: :stats, as: :fetch forward_events :p, to: :network, as: :ping end Update = from_router # ... Model, Init, View below end Declare routes and event handlers. The router generates Update for you. Use guards to ignore messages when needed. ==== CLI The <tt>rooibos</tt> command scaffolds projects and runs applications. rooibos new my_app # Generate project structure rooibos run # Run the app in current directory Generated apps include tests, type signatures, and a working welcome screen with keyboard and mouse support. --- === The Ecosystem \Rooibos builds on RatatuiRuby[https://www.ratatui-ruby.dev], a Rubygem built on Ratatui[https://ratatui.rs]. You get native performance with the joy of Ruby. \Rooibos is one way to manage state and composition. Kit is another. ==== Rooibos[https://www.rooibos.run] 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. --- === Links [Get Started] {Getting Started}[https://www.rooibos.run/docs/trunk/doc/getting_started/index_md.html], {Tutorial}[https://www.rooibos.run/docs/trunk/doc/tutorial/index_md.html], {Examples}[https://www.rooibos.run/docs/trunk/examples/app_fractal_dashboard/README_md.html] [Coming From...] {React/Redux}[https://www.rooibos.run/docs/trunk/doc/getting_started/for_react_developers_md.html], {BubbleTea}[https://www.rooibos.run/docs/trunk/doc/getting_started/for_go_developers_md.html], {Textual}[https://www.rooibos.run/docs/trunk/doc/getting_started/for_python_developers_md.html] [Learn More] {Essentials}[https://www.rooibos.run/docs/trunk/doc/essentials/index_md.html], {Scaling Up}[https://www.rooibos.run/docs/trunk/doc/scaling_up/index_md.html], {Best Practices}[https://www.rooibos.run/docs/trunk/doc/best_practices/index_md.html], {Troubleshooting}[https://www.rooibos.run/docs/trunk/doc/troubleshooting/index_md.html] [Community] {Forum}[https://forum.setdef.com/c/rooibos], {Announcements}[https://forum.setdef.com/tags/c/rooibos/announcement], {Bug Tracker}[https://forum.setdef.com/tags/c/rooibos/bug], {Contribution Guide}[https://github.com/setdef/Rooibos/blob/trunk/CONTRIBUTING.md], {Code of Conduct}[https://github.com/setdef/Rooibos/blob/trunk/CODE_OF_CONDUCT.md] --- [Website] https://rooibos.run [Source] https://github.com/setdef/Rooibos [RubyGems] https://rubygems.org/gems/rooibos © 2026 Kerrick Long · Library: LGPL-3.0-or-later · Website: CC-BY-NC-ND-4.0 · Snippets: MIT-0
