Type declaration

const regex: (searchString: RegExp) => Parser;

Example

In this example we are going to parse the strings "Hello" and "Hallo" using the same parser.

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

const regexParser = regex(/H[ae]llo/);
const parser = sequenceOf([regexParser(), whitespace(), regexParser()]);

const result = parser.run(`Hello Hallo`);

The result of the parser above will be:

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