Retro Edit

Retro Edit is a lightweight, customizable code editor built in Java using Swing. It provides a modern, efficient coding environment with advanced features such as syntax highlighting, code folding, auto-completion, and an integrated file manager. The application uses a modular architecture with decoupled components that communicate via an event bus, making it easy to extend and maintain.

Features

• Tabbed Editing:
  Open, close, and manage multiple files in separate tabs.

• Syntax Highlighting & Code Folding:
  Supports multiple languages including Java, Python, C, C++, JSON, and Go using RSyntaxTextArea.

• Auto-Completion:
  Provides basic auto-completion for Java keywords and shorthand completions (e.g., sysout for System.out.println).

• Find/Replace & Go-To Line:
  Built-in dialogs and actions for searching, replacing, and navigating to specific lines in your code.

• File Management:

  • Directory Tree: Browse files and directories with drag-and-drop support and context menus.
  • File Open/Save: Choose files using native file dialogs or custom dialogs based on the interface theme.

• Dynamic Theming:
  Switch between themes (e.g., retro/light/dark) dynamically. The ThemeManager applies the appropriate look-and-feel and icon resources.

• Custom Logging & Settings:

  • Logging: A lightweight logging system that prints messages to the console.
  • Settings: A JSON-based configuration system that allows you to customize fonts, themes, and other options.
