RayEdit - Proof-of-Concept Code Editor

⚠️ This is a completed proof-of-concept project with no further development planned.

A demonstration of how to build a functional code editor using Raylib-cs and C#. This project serves as an educational example and technical showcase, illustrating the implementation of core text editing features specifically for C# development.

🚀 Features

✨ Core Functionality

• Complete text editing with cursor navigation and text selection
• Syntax highlighting for C# code with keyword recognition
• Automatic indentation when pressing Enter in C# files
• Auto-completion with C# keywords and previously written words
• Undo/Redo system with intelligent action grouping
• File management (Open, Save, New file creation)

🎯 C#-Specific Features

• Intelligent Auto-Completion: Suggests C# keywords and previously used terms
• Automatic bracket completion: (), {}, [], "", ''
• Smart Indentation: Maintains indentation on new lines
• Syntax Highlighting: Recognizes C# keywords, strings, comments and more

⌨️ Keyboard Shortcuts

• Ctrl + S: Save file
• Ctrl + O: Open file
• Ctrl + C/V/X: Copy/Paste/Cut
• Ctrl + A: Select all
• Ctrl + Z/Y: Undo/Redo
• Ctrl + P: Open Command Palette
• Ctrl + Space: Manually trigger auto-completion
• Tab: Insert 4 spaces
• Escape: Return to main menu

🎮 Command Palette

Advanced command palette with over 20 integrated commands:

• File Operations: save, open, new, save-as
• Editing: undo, redo, copy, paste, cut, select-all
• Navigation: goto-line, goto-start, goto-end
• Search: find, replace (planned)
• Utilities: word-count, clear, insert-date

🛠️ Technical Details

Architecture

• Frontend: Raylib-cs for rendering and input handling
• Backend: C# .NET for logic and data processing
• Modular Design: Separate components for different functionalities

Main Components

• EditorView: Main view with input handling and rendering
• TextBuffer: Manages text content, cursor and selection
• AutoCompletion: Intelligent completion for C# and text documents
• CommandRegistry: Extensible command system
• SyntaxHighlighter: Syntax highlighting for various file types
• UndoRedoManager: Undo/Redo functionality with action grouping

Performance Optimizations

• Efficient text rendering with scrolling support
• Intelligent cursor positioning with precise text measurement
• Optimized auto-completion with limited suggestions
• Lazy loading for large files

🎯 Purpose & Target Audience

This completed proof-of-concept is intended for:

• Developers studying text editor implementation techniques
• Students learning about text processing and GUI development
• Raylib enthusiasts exploring desktop application development
• Educators looking for practical examples of C# and Raylib-cs integration

Note: This project is not intended for production use and will not receive updates or new features.
