Features

• Educational Programming Environments - Serves as a foundation for integrated platforms that teach software development concepts through visual block editors.
• Block-Based Visual Interfaces - Implements a drag-and-drop interlocking block editor for building logic without manual coding.
• Blockly Extensions - Implemented as a specialized extension of the Google Blockly ecosystem for educational scripting.
• Visual Programming Tools - Provides an environment for creating graphical programming interfaces that define application logic through interlocking blocks.
• Visual Block Designers - Provides an interface for designing specialized graphical components that represent specific functions in a visual language.
• Visual Language Frameworks - Provides a framework for defining the shapes, behaviors, and input fields of custom blocks for domain-specific languages.
• Block-Based Code Generators - Translates visual arrangements of interlocking blocks into executable source code for beginners and students.
• Block-Based Coding Libraries - Provides a comprehensive framework for creating visual programming languages that translate block arrangements into executable code.
• Visual Block Schemas - Uses configuration-driven schemas to define the visual appearance and connectivity rules of programming blocks.
• No-Code Platforms - Enables the development of software that allows non-programmers to build complex workflows using a visual block system.
• JSON Serializers - Converts nested block hierarchies into structured JSON trees for saving and loading program state.
• Workspace Coordinate Management - Manages a global 2D workspace coordinate system for free-form movement, zooming, and panning of visual blocks.
• Event-Driven Input Handlers - Utilizes a centralized event system to map mouse and keyboard inputs to mutations of visual programming blocks.
• Block Snapping Logic - Implements constraint-based snapping to ensure programming blocks align correctly during drag-and-drop interactions.
