Ember-konami

A component to recognize the konami code.

{{#konami-code action=(action "codeWasMatched")}}
    {{!keyboard input inside here will be recognized}}
{{/konamic-code}}

The main point was to have some fun with ember-concurrency to see if the entire sequence recognition could be modeled as a single if statement, and lo and behold it worked!

The main component looks like this.

export default Ember.Component.extend({
  layout: layout,

  match: task(function* () {
    if (yield this.up()) {
      if (yield this.down()) {
        if (yield this.down()) {
          if (yield this.left()) {
            if (yield this.right()) {
              if (yield this.left()) {
                if (yield this.right()) {
                  if (yield this.b()) {
                    if (yield this.a()) {
                      if (yield this.b()) {
                        if (yield this.a()) {
                          this.sendAction('action');
                        }
                      }
                    }
                  }
                }
              }
            }
          }
        }
      }
    }
  }).drop(),
})

fun!
