Crate textum 

A syntactic patching library with character-level granularity.

textum provides a robust way to apply patches to source files using rope data structures for efficient editing and tree-sitter for syntactic awareness. Unlike traditional line-based patch formats, textum operates at character granularity and can compose multiple patches with automatic offset tracking.

Examples

use textum::{Patch, PatchSet};
use ropey::Rope;

let mut rope = Rope::from_str("hello world");
let patch = Patch {
    file: "test.txt".to_string(),
    range: (6, 11),
    replacement: Some("rust".into()),
    symbol_path: None,
    max_line_drift: None,
};

patch.apply(&mut rope).unwrap();
assert_eq!(rope.to_string(), "hello rust");
