Results for logic-lib

Re-worked from softwear-lib gem. Error reporting and common gems/logic for all softwear apps.

Shot Libs implements a series of Loaders, which can be used to obtain instances of Helpers and Libraries, to extract business logic from your MVC application.

A Ruby port of `HTML::Template::Pro'. `HTML::Template::Pro' is template engine originally written in Perl and XS. It's so fast because of its C based implementation. Its syntax is very simple. This results clearly separation of application logic and its view. Template syntax complies with original perl module's syntax. Please see, HTML::Template::SYNTAX[http://search.cpan.org/~viy/HTML-Template-Pro-0.92/lib/HTML/Template/SYNTAX.pod#SYNOPSIS].

I believe that some of developers faced a situation when you can't convince your customer | project manager | team lead | teammates to use any of existing business logic handler, as they think it: - has no value for business - is hard to integrate - needs to be learned be developers - is no guarantee that this gem will be well maintained in the future - is developed by no name author But you still want to make your controllers and models as thin as possible. If such situation is familiar for you then this gem is for you. This is a one file gem, just copy `Service` class from `lib/simple_logic_step.rb` to your project and specs for it from `spec/simple_logic_step/logic_step_spec.rb`.

# Studio Game Studio Game is a Ruby-based project that demonstrates object-oriented programming concepts. It includes classes and modules to manage players, games, and scoring. ## Project Structure - `lib/`: Contains the core Ruby files for the game logic. - `game.rb`: Defines the main game class. - `player.rb`: Manages player attributes and behaviors. - `treasure_trove.rb`: Handles treasures and their values. - `bin/`: Contains executable scripts to run the game. - `studio_game`: The main entry point to start the game. - `spec/`: Contains unit tests for the game. - `game_spec.rb`: Tests for the game class. - `player_spec.rb`: Tests for the player class. - `README.md`: Project documentation. - `LICENSE`: MIT License file. ## How to Run 1. Clone the repository. 2. Navigate to the `studio_game` directory. 3. Run the game using: ```bash ruby bin/studio_game ``` ## Testing To ensure the game logic works as expected, run the unit tests included in the `spec/` directory. Use the following command: ```bash rspec spec/ ``` This will execute all the test files and display the results in the terminal.

Inventory Inventory keeps track of the contents of your Ruby¹ projects. Such an inventory can be used to load the project, create gem specifications and gems, run unit tests, compile extensions, and verify that the project’s content is what you think it is. ¹ See http://ruby-lang.org/ § Usage Let’s begin by discussing the project structure that Inventory expects you to use. It’s pretty much exactly the same as the standard Ruby project structure¹: ├── README ├── Rakefile ├── lib │ ├── foo-1.0 │ │ ├── bar.rb │ │ └── version.rb │ └── foo-1.0.rb └── test └── unit ├── foo-1.0 │ ├── bar.rb │ └── version.rb └── foo-1.0.rb Here you see a simplified version of a project called “Foo”’s project structure. The only real difference from the standard is that the main entry point into the library is named “foo-1.0.rb” instead of “foo.rb” and that the root sub-directory of “lib” is similarly named “foo-1.0” instead of “foo”. The difference is the inclusion of the API version. This must be the major version of the project followed by a constant “.0”. The reason for this is that it allows concurrent installations of different major versions of the project and means that the wrong version will never accidentally be loaded with require. There’s a bigger difference in the content of the files. ‹Lib/foo-1.0/version.rb› will contain our inventory instead of a String: require 'inventory-1.0' class Foo Version = Foo.new(1, 4, 0){ authors{ author 'A. U. Thor', 'a.u.thor@example.org' } homepage 'http://example.org/' licenses{ license 'LGPLv3+', 'GNU Lesser General Public License, version 3 or later', 'http://www.gnu.org/licenses/' } def dependencies super + Dependencies.new{ development 'baz', 1, 3, 0 runtime 'goo', 2, 0, 0 optional 'roo-loo', 3, 0, 0, :feature => 'roo-loo' } end def package_libs %w[bar.rb] end } end We’re introducing quite a few concepts at once, and we’ll look into each in greater detail, but we begin by setting the ‹Version› constant to a new instance of an Inventory with major, minor, and patch version atoms 1, 4, and 0. Then we add a couple of dependencies and list the library files that are included in this project. The version numbers shouldn’t come as a surprise. These track the version of the API that we’re shipping using {semantic versioning}². They also allow the Inventory#to_s method to act as if you’d defined Version as ‹'1.4.0'›. Next follows information about the authors of the project, the project’s homepage, and the project’s licenses. Each author has a name and an email address. The homepage is simply a string URL. Licenses have an abbreviation, a name, and a URL where the license text can be found. We then extend the definition of ‹dependencies› by adding another set of dependencies to ‹super›. ‹Super› includes a dependency on the version of the inventory project that’s being used with this project, so you’ll never have to list that yourself. The other three dependencies are all of different kinds: development, runtime, and optional. A development dependency is one that’s required while developing the project, for example, a unit-testing framework, a documentation generator, and so on. Runtime dependencies are requirements of the project to be able to run, both during development and when installed. Finally, optional dependencies are runtime dependencies that may or may not be required during execution. The difference between runtime and optional is that the inventory won’t try to automatically load an optional dependency, instead leaving that up to you to do when and if it becomes necessary. By that logic, runtime dependencies will be automatically loaded, which is a good reason for having dependency information available at runtime. The version numbers of dependencies also use semantic versioning, but note that the patch atom is ignored unless the major atom is 0. You should always only depend on the major and minor atoms. As mentioned, runtime dependencies will be automatically loaded and the feature they try to load is based on the name of the dependency with a “-X.0” tacked on the end, where ‘X’ is the major version of the dependency. Sometimes, this isn’t correct, in which case the :feature option may be given to specify the name of the feature. You may also override other parts of a dependency by passing in a block to the dependency, much like we’re doing for inventories. The rest of an inventory will list the various files included in the project. This project only consists of one additional file to those that an inventory automatically include (Rakefile, README, the main entry point, and the version.rb file that defines the inventory itself), namely the library file ‹bar.rb›. Library files will be loaded automatically when the main entry point file loads the inventory. Library files that shouldn’t be loaded may be listed under a different heading, namely “additional_libs”. Both these sets of files will be used to generate a list of unit test files automatically, so each library file will have a corresponding unit test file in the inventory. We’ll discuss the different headings of an inventory in more detail later on. Now that we’ve written our inventory, let’s set it up so that it’s content gets loaded when our main entry point gets loaded. We add the following piece of code to ‹lib/foo-1.0.rb›: module Foo load File.expand_path('../foo-1.0/version.rb', __FILE__) Version.load end That’s all there’s to it. The inventory can also be used to great effect from a Rakefile using a separate project called Inventory-Rake³. Using it’ll give us tasks for cleaning up our project, compiling extensions, installing dependencies, installing and uninstalling the project itself, and creating and pushing distribution files to distribution points. require 'inventory-rake-1.0' load File.expand_path('../lib/foo-1.0/version.rb', __FILE__) Inventory::Rake::Tasks.define Foo::Version Inventory::Rake::Tasks.unless_installing_dependencies do require 'lookout-rake-3.0' Lookout::Rake::Tasks::Test.new end It’s ‹Inventory::Rake::Tasks.define› that does the heavy lifting. It takes our inventory and sets up the tasks mentioned above. As we want to be able to use our Rakefile to install our dependencies for us, the rest of the Rakefile is inside the conditional #unless_installing_dependencies, which, as the name certainly implies, executes its block unless the task being run is the one that installs our dependencies. This becomes relevant when we set up Travis⁴ integration next. The only conditional set-up we do in our Rakefile is creating our test task via Lookout-Rake⁵, which also uses our inventory to find the unit tests to run when executed. Travis integration is straightforward. Simply put before_script: - gem install inventory-rake -v '~> VERSION' --no-rdoc --no-ri - rake gem:deps:install in the project’s ‹.travis.yml› file, replacing ‹VERSION› with the version of Inventory-Rake that you require. This’ll make sure that Travis installs all development, runtime, and optional dependencies that you’ve listed in your inventory before running any tests. You might also need to put env: - RUBYOPT=rubygems in your ‹.travis.yml› file, depending on how things are set up. ¹ Ruby project structure: http://guides.rubygems.org/make-your-own-gem/ ² Semantic versioning: http://semver.org/ ³ Inventory-Rake: http://disu.se/software/inventory-rake-1.0/ ⁴ Travis: http://travis-ci.org/ ⁵ Lookout-Rake: http://disu.se/software/lookout-rake-3.0/ § API If the guide above doesn’t provide you with all the answers you seek, you may refer to the API¹ for more answers. ¹ See http://disu.se/software/inventory-1.0/api/Inventory/ § Financing Currently, most of my time is spent at my day job and in my rather busy private life.

Contentful API wrapper library exposing an ActiveRecord-like interface

== 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
