The Dinghy Diff library facilitates tree comparison between two Abstract Syntax Tree (AST) elements. It offers support for various operations such as add, remove, update, and move. This library builds upon the groundwork laid by @Toemmsche.

const dinghyDiff = require("@tdurieux/dinghy-diff");
// Calculate the difference between two source files
const oldPath = "path/to/original/document";
const newPath = "path/to/changed/document";
const tNodeSerDes = new dinghyDiff.ASTDataSerDes();
const oldTree = tNodeSerDes.parseFromString(fs.readFileSync(oldPath).toString());
const newTree = tNodeSerDes.parseFromString(fs.readFileSync(newPath).toString());
const editScript: dinghyDiff.EditScript<dinghyDiff.ASTData> = new dinghyDiff.SemanticDiff<dinghyDiff.ASTData>(dinghyDiff.defaultDiffOptions).diff(
oldTree,
newTree
);
