Regular expression for matching mapcodes

mapcode-regex

Regular expression for matching mapcodes

Install

npm install mapcode-regex

Usage

import mapcodeRegex from 'mapcode-regex';

mapcodeRegex().test('4J.Q2');
//=> true

mapcodeRegex().test('Hawaii ZSR.3J');
//=> true

mapcodeRegex().exec('This is a mapcode FRA 4J.Q2')[0];
//=> 'FRA 4J.Q2'

'Multiple FRA 4J.Q2 Hawaii ZSR.3J mapcodes'.match(mapcodeRegex());
//=> ['FRA 4J.Q2', 'Hawaii ZSR.3J']

Important

If you run the regex against untrusted user input in a server context, you should give it a timeout.

I do not consider ReDoS a valid vulnerability for this package.

Tip

You can use clone-regexp to change the flags. In this case, maybe remove the global flag.

mapcode-regex's Issues

Make regex stricter

Continuation of #1.

Alright, got a reply with what's needed an more. Looks like there are more things we can implement to make it even stricter: https://dl.dropboxusercontent.com/u/71884/Length%20and%20format%20of%20mapcodes.pdf

Max length on main mapcode pieces?

I need to figure out if there's a max length on the main mapcode pieces.

Example: ZSR and 3J in Hawaii ZSR.3J.

From looking at a bunch of codes I would guess it's minimum 2 and maximum 5. But can't be sure until I see some documentation on it.
