Mirror some version of gems with Gem::Version DSL Create a mini_gem file and add this to it : source :gemcutter gem 'rails', ['~> 1.2.0', '>= 3.0'] or source :gemcutter resource :path => '/your_path/mini_gem.yml' # /your_path/mini_gem.yml gem: - rails: - - '~> 1.2.0' - '>= 3.0' It will solve the dependencies for you so you don't have to write an exhaustive list of the gems you want to mirror

A Ruby gem for building API clients through declarative configuration. Features include automatic HTTP method detection, nested routing, streaming support, configurable retries, and security features like SSL verification, SSRF protection, and path traversal prevention. Define your API endpoints with a clean DSL and get comprehensive error handling, debugging capabilities, and optional ActiveSupport integration for logging and instrumentation.

A DSL for building matchers that validate nested data structures. Ruby literals like classes, ranges, regexps, arrays, and hashes are automatically converted into matchers. Mismatches produce error trees with paths pointing to each failing element.

== Baf baf helps writing an user acceptance test suite with a dedicated library and cucumber steps. It can run and wait for programs in a modified environment, verify the exit status, the output streams and other side effects. It also supports interactive programs and writing to their standard input. Then, it provides a DSL to write the CLI: require 'baf/cli' module MyProgram class CLI < Baf::CLI def setup flag_version '0.1.2'.freeze option :c, :config, 'config', 'specify config file' do |path| @config_path = path end end def run usage! unless arguments.any? puts 'arguments: %s' % arguments puts 'config: %s' % @config_path if @config_path end end end MyProgram::CLI.run ARGV Which behaves this way: % ./my_program Usage: my_program [options] options: -c, --config config specify config file -h, --help print this message -V, --version print version zsh: exit 64 ./my_program % ./my_program --wrong-arg Usage: my_program [options] options: -c, --config config specify config file -h, --help print this message -V, --version print version zsh: exit 64 ./my_program --wrong-arg % ./my_program foo arguments ["foo"] % ./my_program -c some_file foo arguments ["foo"] config path some_file

Sashiko is a small Ruby gem that adds a declarative span DSL on top of OpenTelemetry, plus helpers for keeping trace context attached as work crosses Thread, Fiber, queue, HTTP, and Ractor boundaries. Includes a span-replay mechanism for emitting spans from Ractor workers, optional Faraday and Anthropic adapters, RBS signatures, and a Ruby::Box-aware `tracer:` injection path for multi-tenant observability.

StandardLedger captures the recurring 'append-only entry → N projection updates' pattern as a declarative DSL on host ActiveRecord models. Supports five projection modes — :inline, :async, :sql, :matview, :trigger — plus a deterministic rebuild path from the entry log, ad-hoc materialized view refresh, and a doctor rake task that verifies host-owned trigger presence. Enforces idempotency-by-unique-index and immutability at the entry level.

== 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.

# SecureDataBag / Knife Secure Bag Knife Secure Bag provides a consistent interface to DataBagItem, EncryptedDataBagItem as well as the custom created SecureDataBagItem while also providing a few extra handy features to help in your DataBag workflows. SecureDataBagItem, can not only manage your existing DataBagItems and EncryptedDataBagItems, but it also provides you with a DataBag type which enables you to selectively encrypt only some of the fields in your DataBag thus allowing you to be able to search for the remaining fields. ## Installation To build and install the plugin add it your Gemfile or run: ```shell gem install secure_data_bag ``` ## Configuration #### Knife Secure Bag Defaults for the Knife command may be provided in your _knife.rb_ file. ```ruby knife[:secure_data_bag][:encrypted_keys] = %w( password ssh_keys ssh_ids public_keys private_keys keys secret ) knife[:secure_data_bag][:secret_file] = "#{local_dir}/secret.pem" knife[:secure_data_bag][:export_root] = "#{kitchen_dir}/data_bags" knife[:secure_data_bag][:export_on_upload] = true knife[:secure_data_bag][:defaults][:secrets][:export_format] = 'plain' ``` To break this up: `knife[:secure_data_bag][:encrypted_keys] = []` When Knife Secure Bag encrypts a hash with an _encryption format_ of *nested*, it will recursively walk through the hash from the bottom up and encrypt any key found within this array. `knife[:secure_data_bag][:secret_file]` When encryption is required, the shared secret found at this location will be loaded. `knife[:secure_data_bag][:export_root]` When exporting a data\_bag\_item, files will be created in below this root directory. Typically this would be the data\_bag folder located within your kitchen. `knife[:secure_data_bag][:export_on_upload]` When a data\_bag\_item is edited using `knife secure bag edit`, it may be automatically exported to the _export\_root_. `knife[:secure_data_bag][:defaults][:secrets][:export_format]` The configuration file additionally supports the _defaults_ hash which provides default values for all _command line arguments_ that one might use. Of all of them only the _export\_format_ key is likely to be of much use. ## Examples #### Chef cookbook recipe ```ruby metadata = {} # Define the keys we wish to encrypt metadata[:encrypted_keys] = %w(encoded) # Optionally load a specific shared secret. Otherwise, the global # encrypted\_data\_bag\_secret will be automatically used. secret_key = SecureDataBagItem.load_key("/path/to/secret") # Create a hash of data to use as an exampe raw_data = { id: "item", data_bag: "data_bag", encoded: "my string", unencoded: "other string" } # Instantiate a SecureDataBagItem from a hash item = SecureDataBagItem.from_hash(data, metadata) # Or more explicitely item = SecureDataBagItem.from_hash(data, encrypted_keys: %w(encoded)) # Or load from server item = SecureDataBagItem.load("data_bag", "item") # Print the un-encrypted raw data pp item.raw_data # Print the un-encrypted `encoded` key pp item['encoded'] # Print the encrypted hash as a data_bag_item hash pp item.to_hash =begin { id: "item", data_bag: "data_bag", encoded: { encrypted_data: "encoded", cipher: aes-256-cbc, iv: 13453453dkgfefg== version: 1 } unencoded: "other string", } =end ``` ## Usage #### Knife commands Print an DataBagItem, EncryptedDataBagItem or SecureDataBagItem, auto-detecting the encryption method used as plain text. ```shell knife secure bag show -F js secrets secret_item ``` Print an DataBagItem, EncryptedDataBagItem or SecureDataBagItem, auto-detecting the encryption method used as a SecureDataBagItem in encrypted format. ```shell knife secure bag show -F js secrets secret_item --enc-format nested ``` Edit an EncryptedDataBagItem, preserve it's encryption type, and export a copy to the _data\_bag_ folder in your kitchen. ```shell knife secure bag edit secrets secret_item --export ``` ## Knife SubCommands Most of the SubCommands support the following command-line options: `--enc-format [plain,encrypted,nested]` Ensure that, when displaying or uploading the data\_bag\_item, we forcibly encrypt the data\_bag\_item using the specified format instead of preserving the existing format. In this case: - plain: refers to a DataBagItem - encrypted: refers to an EnrytpedDataBagItem - nested: refers to a SecureDataBagItem `--dec-format [plain,encrypted,nested]` Attempt to decrypt the data\_bag\_item using the given format rather than the auto-detected one. The only real reason to use this is when you wish to specifically select _plain_ as the format so as to not decrypt the item. `--enc-keys key1,key2,key3` Provide a comma delimited list of hash keys which should be encrypted when encrypting the data\_bag\_item. This list will be concatenated with any key names listed in the configuration file or which were previously encrypted. `--export` Export the data\_bag\_item to json file in either of _export-format_ or _enc-format_. `--export-format` Overrides the encryption format only for the _export_ feature. `--export-root` Root directly under which a folder should exist for each _data_bag_ into which to export _data_bag_items_ as json files. When displaying the content of the _data\_bag\_item_, an additional key of *_secure_metadata* will be added to the output which contains gem specific metadata such as the encryption formats and any encrypted keys found. This key will _not_ be saved with the item, however it may be manipulated to alter the behavior of the _edit_ or _export_ commands. #### knife secure bag show DATA_BAG ITEM This command functions just like `knife data bag show` and is used to print out the content of either a DataBagItem, EncryptedDataBagItem or SecureDataBagItem. By default, it will auto-detect the Item type, and print it's unencrypted version to the terminal. This behavior, however, may be altered using the previously mentioned command line options. #### knife secure bag open PATH This commands functions much like `knife secure bag show`, however it is designed to load a _data\_bag\_item_ from disk as opposed to loading it from Chef server. This may be of use when view the content of an exported encrypted file. #### knife secure bag edit DATA_BAG DATA_BAG_ITEM This command functions just like `knife data bag edit` and is used to edit either a DataBagItem, EncryptedDataBagItem or a SecureDataBagItem. It supports all of the same options as `knife secure bag show`. #### knife secure bag from file DATA_BAG PATH This command functions just like `knife data bag from file` and is used to upload either a DataBagItem, EncryptedDataBagItem or a SecureDataBagItem. It supports all of the same options as `knife secure bag show`. ## Recipe DSL The gem additionally provides a few Recipe DSL methods which may be useful. ```ruby load_secure_item = secure_data_bag_item( data_bag_name, data_bag_item, cache: false ) load_plain_item = data_bag_item(data_bag_name, data_bag_item) convert_plain_to_secure = secure_data_bag_item!(load_plain_item) ```
