Command Interface Layer

Provides a unified command interface for convenient frontend integration.

Overview

The Command Interface Layer is the primary entry point for Editor Core, wrapping all underlying components in a unified command pattern. It supports the following types of operations:

• Text Editing: Insert, delete, and replace text
• Cursor Operations: Move cursor and set selection range
• View Management: Set viewport, scroll, and get visible content
• Style Control: Add/remove styles and code folding

Example

use editor_core::{CommandExecutor, Command, EditCommand};

let mut executor = CommandExecutor::empty(80);

// Insert text
executor.execute(Command::Edit(EditCommand::Insert {
    offset: 0,
    text: "Hello, World!".to_string(),
})).unwrap();

// Batch execute commands
let commands = vec![
    Command::Edit(EditCommand::Insert { offset: 0, text: "Line 1\n".to_string() }),
    Command::Edit(EditCommand::Insert { offset: 7, text: "Line 2\n".to_string() }),
];
executor.execute_batch(commands).unwrap();
