Debuggers are great! They help us troubleshoot complicated programming problems by inspecting values produced by code, line by line. They are invaluable when trying to understand what is going on in a large application composed of thousands or millions of lines of code. In day-to-day test-driven development and simple debugging though, a puts statement can be a lot quicker in revealing what is going on than halting execution completely just to inspect a single value or a few. This is certainly true when writing the simplest possible code that could possibly work, and running a test every few seconds or minutes. Problem is you need to locate puts statements in large output logs, know which file names, line numbers, classes, and methods contained the puts statements, find out what variable names are being printed, and see nicely formatted output. Enter puts_debuggerer. A guilt-free puts debugging Ruby gem FTW that prints file names, line numbers, class names, method names, and code statements; and formats output nicely courtesy of awesome_print.

Glimmer DSL for SWT (JRuby Desktop Development Cross-Platform Native GUI Framework) is a native-GUI cross-platform desktop development library written in JRuby, an OS-threaded faster JVM version of Ruby. It includes SWT 4.30 (released on December 1, 2023). Glimmer's main innovation is a declarative Ruby DSL that enables productive and efficient authoring of professional-grade desktop applications by relying on the robust Eclipse SWT library, with the familiar native look, feel, and behavior of GUI on Mac, Windows, and Linux. Glimmer additionally innovates by having built-in data-binding support, which greatly facilitates synchronizing the GUI with domain models, thus achieving true decoupling of object oriented components and enabling developers to solve business problems (test-first) without worrying about GUI concerns, or alternatively drive development GUI-first, and then write clean business models (test-first) afterwards. Not only does Glimmer provide a large set of GUI widgets, but it also supports drawing Canvas Graphics like Shapes and Animations. To get started quickly, Glimmer offers scaffolding options for Apps, Gems, and Custom Widgets. Glimmer also includes native-executable packaging support, sorely lacking in other libraries, thus enabling the delivery of desktop apps written in Ruby as truly native DMG/PKG/APP files on the Mac, MSI/EXE files on Windows, and DEB/RPM files on Linux. Glimmer was the first Ruby gem to bring SWT (Standard Widget Toolkit) to Ruby, thanks to creator Andy Maleh, EclipseCon/EclipseWorld/RubyConf speaker. If you liked Shoes, You'll love Glimmer!

Glimmer DSL for Web (Ruby in the Browser Web Frontend Framework) enables building Web Frontends using Ruby in the Browser, as per Matz's recommendation in his RubyConf 2022 keynote speech to replace JavaScript with Ruby. It aims at providing the simplest, most intuitive, most straight-forward, and most productive frontend framework in existence. The framework follows the Ruby way (with DSLs and TIMTOWTDI) and the Rails way (Convention over Configuration) in building Isomorphic Ruby on Rails Applications. It provides a Ruby HTML DSL, which uniquely enables writing both structure code and logic code in one language. It supports both Unidirectional (One-Way) Data-Binding (using <=) and Bidirectional (Two-Way) Data-Binding (using <=>). Dynamic rendering (and re-rendering) of HTML content is also supported via Content Data-Binding. Modular design is supported with Glimmer Web Components, Component Slots, and Component Custom Event Listeners. And, a Ruby CSS DSL is supported with the included Glimmer DSL for CSS. Many samples are demonstrated in the Rails sample app (there is a very minimal Standalone [No Rails] sample app too). You can finally live in pure Rubyland on the Web in both the frontend and backend with Glimmer DSL for Web! This gem relies on Opal Ruby.

CryptoPunks GUI for Simplified Minting - Built with Glimmer DSL for Tk (requires ActiveTcl to run cryptopunks-gui command)

Glimmer DSL for Tk (Ruby Tk Desktop Development GUI Library) - Ruby DSL for Tcl/Tk with bidirectional/unidirectional data-binding support.

if/case conditionals can get really hairy in highly sophisticated business domains. Domain model inheritance can help remedy the problem, but you don't want to dump all logic variations in the same domain models. Strategy Pattern solves that problem by externalizing logic variations to separate classes outside the domain models. One difficulty with implementing Strategy Pattern is making domain models aware of newly added strategies without touching their code (Open/Closed Principle). Strategic solves that problem by supporting Strategy Pattern with automatic discovery of strategies and ability fetch the right strategy without conditionals. This allows you to make any domain model "strategic" by simply following a convention in the directory/namespace structure you create your strategies under so that the domain model automatically discovers all available strategies.

abstract_feature_branch is a Ruby gem that provides a unique variation on the Branch by Abstraction Pattern by Paul Hammant and the Feature Toggles Pattern by Martin Fowler to enhance team productivity and improve software fault tolerance. It provides the ability to wrap blocks of code with an abstract feature branch name, and then specify in a configuration file which features to be switched on or off. The goal is to build out upcoming features in the same source code repository branch (i.e. Continuous Integration and Trunk-Based Development), regardless of whether all are completed by the next release date or not, thus increasing team productivity by preventing integration delays. Developers then disable in-progress features until they are ready to be switched on in production, yet enable them locally and in staging environments for in-progress testing. This gives developers the added benefit of being able to switch a feature off after release should big problems arise for a high risk feature. abstract_feature_branch additionally supports Domain Driven Design's pattern of Bounded Contexts by allowing developers to configure context-specific feature files if needed. abstract_feature_branch is one of the simplest and most minimalistic "Feature Flags" Ruby gems out there as it enables you to get started very quickly by simply leveraging YAML files without having to set up a data store if you do not need it (albeit, you also have the option to use Redis as a very fast in-memory data store).

Glimmer DSL for GTK - Ruby-GNOME Desktop Development GUI Library - Supports all GTK widgets and Cairo graphics

Glimmer DSL for Opal on Rails (Pure Ruby Web GUI and Auto-Webifier of Desktop Apps)

Perfect Shape is a collection of pure Ruby geometric algorithms that are mostly useful for GUI manipulation like checking viewport rectangle intersection or containment of a mouse click point in popular geometry shapes such as rectangle, square, arc (open, chord, and pie), ellipse, circle, polygon, and paths containing lines, quadratic bézier curves, and cubic bezier curves, potentially with affine transforms applied like translation, scale, rotation, shear/skew, and inversion (including both the Ray Casting Algorithm, aka Even-odd Rule, and the Winding Number Algorithm, aka Nonzero Rule). Additionally, it contains some purely mathematical algorithms like IEEEremainder (also known as IEEE-754 remainder).
