God it's about every day where I think to myself, gadzooks, I keep typing *REPETITIVE_BORING_TASK* over and over. Wouldn't it be great if I had something like boom to store all these commonly-used text snippets for me? Then I realized that was a worthless idea since boom hadn't been created yet and I had no idea what that statement meant. At some point I found the code for boom in a dark alleyway and released it under my own name because I wanted to look smart.
This is a fork of Zach Holman's amazing boom. Explanation for the fork follows Zach's intro to boom: God it's about every day where I think to myself, gadzooks, I keep typing *REPETITIVE_BORING_TASK* over and over. Wouldn't it be great if I had something like boom to store all these commonly-used text snippets for me? Then I realized that was a worthless idea since boom hadn't been created yet and I had no idea what that statement meant. At some point I found the code for boom in a dark alleyway and released it under my own name because I wanted to look smart. Explanation for my fork: Zach didn't fancy changing boom a great deal to handle the case of remote and local boom repos. Which is fair enough I believe in simplicity. But I also believe in getting tools to do what you want them to do. So with boom, you can change your storage with a 'boom storage' command, but that's a hassle when you want to share stuff. So kaboom does what boom does plus simplifies maintaining two boom repos. What this means is that you can pipe input between remote and local boom instances. My use case is to have a redis server in our office and be able to share snippets between each other, but to also be able to have personal repos. It's basically something like distributed key-value stores. I imagine some of the things that might be worth thinking about, based on DVC are: Imports/Exports of lists/keys/values between repos. Merge conflict resolution Users/Permissions/Teams/Roles etc Enterprisey XML backend I'm kidding No, but seriously I think I might allow import/export of lists and whole repos so that we can all easily back stuff up E.g. clone the whole shared repo backup your local repo to the central one underneath a namespace

Morning Glory Morning Glory is comprised of a rake task and helper methods that manages the deployment of static assets into an Amazon CloudFront CDN's S3 Bucket, improving the performance of static assets on your Rails web applications. _NOTE: You will require an Amazon Web Services (AWS) account in order to use this gem. Specially: S3 for storing the files you wish to distribute, and CloudFront for CDN distribution of those files._ This version of Morning Glory works with Rails 3.x and Ruby 1.9.x h2. What does it do? Morning Glory provides an easy way to deploy Ruby on Rails application assets to the Amazon CloudFront CDN. It solves a number of common issues with S3/CloudFront. For instance, CloudFront won't automatically expire old assets stored on edge nodes when you redeploy new assets (the Cloudfront expiry time is 24 hours minimum). To fix this Morning Glory will automatically namespace asset releases for you, then update all references to those renamed assets within your stylesheets ensuring there are no broken asset links. It also provides a helper method to rewrite all standard Rails asset helper generated URLs to your CloudFront CDN distributions, as well as handling switching between HTTP and HTTPS. Morning Glory was also built with SASS (Syntactically Awesome Stylesheets) in mind. If you use Sass for your stylesheets they will automatically be built before deployment to the CDN. See http://sass-lang.com/ for more information on Sass.s h2. What it doesn't do Morning Glory cannot configure your CloudFront distributions for you automatically. You will manually have to login to your AWS Management Console account, "https://console.aws.amazon.com/cloudfront/home":https://console.aws.amazon.com/cloudfront/home, and set up a distribution pointing to an S3 Bucket. h2. Installation <pre> gem 'morning_glory' </pre> h2. Usage Morning Glory provides it's functionality via rake tasks. You'll need to specify the target rails environment configuration you want to deploy for by using the @RAILS_ENV={env}@ parameter (for example, @RAILS_ENV=production@). <pre> rake morning_glory:cloudfront:deploy RAILS_ENV={YOUR_TARGET_ENVIRONMENT} </pre> h2. Configuration h3. The Morning Glory configuration file, @config/morning_glory.yml@ You can specify a configuration section for every rails environment (production, staging, testing, development). This section can have the following properties defined: <pre> --- production: enabled: true # Is MorningGlory enabled for this environment? bucket: cdn.production.foo.com # The bucket to deploy your assets into s3_logging_enabled: true # Log the deployment to S3 revision: "20100317134627" # The revision prefix. This timestamp automatically generateed on deployment delete_prev_rev: true # Delete the previous asset release (save on S3 storage space) </pre> h3. The Amazon S3 authentication keys configuration file, @config/s3.yml@ This file provides the access credentials for your Amazon AWS S3 account. You can configure keys for all your environments (production, staging, testing, development). <pre> --- production: access_key_id: YOUR_ACCESS_KEY secret_access_key: YOUR_SECRET_ACCESS_KEY </pre> Note: If you are deploying your system to Heroku, you can configure your Amazon AWS S3 information with the environment variables S3_KEY and S3_SECRET instead of using a configuration file. h3. Set up an asset_host For each environment that you'd like to utilise the CloudFront CDN for you'll need to define the asset_host within the @config/environments/{ENVIRONMENT}.rb@ configuration file. As of June 2010 AWS supports HTTPS requests on the CloudFront CDN, so you no longer have to worry about switching servers. (Yay!) h4. Example config/environments/production.rb @asset_host@ snippet: Here we're targeting a CNAME domain with HTTP support. <pre> ActionController::Base.asset_host = Proc.new { |source, request| if request.ssl? "#{request.protocol}#{request.host_with_port}" else "#{request.protocol}assets.example.com" end } </pre> h3. Why do we have to use a revision-number/namespace/timestamp? Once an asset has been deployed to the Amazon Cloudfront edge servers it cannot be modified - the version exists until it expires (minimum of 24 hours). To get around this we need to prefix the asset path with a revision of some sort - in MorningGlory's case we use a timestamp. That way you can deploy many times during a 24 hour period and always have your latest revision available on your web site. h2. Dependencies h3. AWS S3 Required for uploading the assets to the Amazon Web Services S3 buckets. See "http://amazon.rubyforge.org/":http://amazon.rubyforge.org/ for more documentation on installation. h2. About the name Perhaps not what you'd expect; a "Morning Glory":http://en.wikipedia.org/wiki/Morning_Glory_cloud is a rare cloud formation observed by glider pilots in Australia (see my side project, "YourFlightLog.com for flight-logging software for paraglider and hang-glider pilots":http://www.yourflightlog.com, from which the Morning Glory plugin was originally extracted).

== 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
