Bred Source Files and Exported Functions

Overview

Bred is an Electron-based code editor that supports multiple editing backends (currently only CodeMirror 6). It is designed as a modern, extensible editor with features commonly found in Emacs-style editors, such as advanced navigation, multiple panes, and customizable key bindings.

The codebase is organized into several categories:

• Core application files that handle initialization and main functionality
• Editor backend implementations for different editing engines
• Electron process communication files for secure context isolation
• Main process file system operations
• Main process specialized functionality (browser, LSP, shell)
• User interface management files (panes, tabs, windows)
• Configuration and utility files
• Extension system files
• Version control integration
• Prompt and execution systems
• Directory and file browsing functionality
