Module diff 

Colored diff rendering widget.

Provides a Diff widget that computes and renders line-level diffs between two texts, supporting both unified and side-by-side display styles.

The diff algorithm uses a simple LCS (Longest Common Subsequence) approach with O(n*m) complexity, suitable for typical text sizes.

Example

use gilt::diff::{Diff, DiffStyle};
use gilt::console::Console;

let old = "fn main() {\n    println!(\"hello\");\n}\n";
let new = "fn main() {\n    println!(\"world\");\n    return;\n}\n";

// Unified diff
let diff = Diff::new(old, new)
    .with_labels("a/main.rs", "b/main.rs");

// Side-by-side diff
let diff = Diff::side_by_side(old, new);
