execall2

execall

Find multiple RegExp matches in a string

Instead of having to iterate over RegExp#exec, immutable, and with a nicer result format.

Install

$ npm install execall2

Usage

import execall from 'execall2';
import * as execall from 'execall2';
import { execall } from 'execall2';
import execall = require('execall2');
const execall = require('execall2');

let t = execall(/(?<k>.)/g, '123456789');

console.dir(t, {
	colors: true,
});

console.log('getOwnPropertyNames', Object.getOwnPropertyNames(t));

let {re, input} = t;

console.log('== hidden property ==');

console.dir({re, input}, {
	colors: true,
});

console.log('== hidden property symbol ==');

// @ts-ignore
console.dir([execall.SYMBOL, t[0][execall.SYMBOL] === t], {
	colors: true,
});

console.log('== JSON.stringify ==');
console.log(JSON.stringify(t));
