Quickstart

After you have installed Rudus you can now create a new TypeScript (or JavaScript) file inside your repo, call it parser.ts for example and copy the example below into it:

import { string, sequenceOf, whitespace } from "rudus";

const parser = sequenceOf([string("Hello"), whitespace(), string("World")]);

const parserResult = parser.run("Hello World");

console.log(parserResult);

And then run that file via ts-node:

npx ts-node parser.ts

In your console you should see an output like this:

{
  "input": "Hello World",
  "isError": false,
  "offset": 11,
  "result": ["Hello", " ", "World"]
}

Congratulations! You have just made and run your first parser which is able to parse the string "Hello World" with Rudus.
