Examples

use ass_editor::{EditorDocument, Position, at_pos};

let mut doc = EditorDocument::from_content("Hello world!").unwrap();

// Note: at_pos! macro doesn't exist in the current implementation
// Using direct methods instead
doc.insert(Position::new(5), " beautiful").unwrap();
assert_eq!(doc.text(), "Hello beautiful world!");
