Strdiff

Strdiff is a library for calculating string differences. It leverages efficient algorithms such as the Levenshtein distance and the Damerau-Levenshtein distance.

How to use:

NOTE: This requires a language that supports WebAssembly

• Install wasmer

Yarn/NPM example

• Install wapm package to yarn project wasmer add --yarn willdera/strdiff

• Install wapm package to npm project wasmer add --npm willdera/strdiff

• Import and use

// index.js
import {bindings} from "@willdera/strdiff";

async function main() {
    const strdiff = await bindings.strdiff();
    
    // tag: 0 -> string
    // tag: 1 -> Vector of string
    let strdiff_check = strdiff.lvd({tag: 0, val: "Hello"}, {tag: 0, val: "Hella"});
    
    // tag: "ok" -> Successful execution
    // tag: "err" -> Failed execution
    console.log(strdiff_check); // { tag: 'ok', val: { tag: 0, val: 1 } }
}

The example above returns a Levenshtein distance of 1, represented as val: 1 in { tag: 0, val: 1 }

NOTE: The example above showcases Levenshtein distance, same approach can be followed for Damerau-Levenshtein distance by replacing strdiff.lvd(...) with strdiff.dlvd(...), same argument data-types would work.
