Wildcard listener not invoked when also matching exact listener

See original GitHub issue

If an event matches both a listener with a wildcard and a listener without, only the non-wildcard listener is invoked. A wildcard listener should not be dependent on if another listener has a “better match”. If this is actually intended behaviour, maybe an option on the constructor could provide both.

Steps to reproduce:

const EventEmitter2 = require('eventemitter2');
const ee = new EventEmitter2({ wildcard: true });

ee.on('A', console.log);
ee.on('B.**', console.log);
ee.on('C', console.log);
ee.on('C.**', console.log);

ee.emit('A', 'A'); // Logs "A" once
ee.emit('B', 'B'); // Logs "B" once
ee.emit('C', 'C'); // Logs "C" only once, not matching wildcard C.**

Expected result A B C C

Actual result A B C
