Add keyboard sequence support to the awesome keymaster.js
npm install @missive/keymaster-sequences
Do you use keymaster.js? Do you want support for key sequences? (Like gmail...) Then you've come to the right place!
This script plugs into keymaster to provide you with support for chaining keypresses together.
Demo: http://jsfiddle.net/ggZxB/1/
``javascript
script[src=keymaster.js]
script[src=keymaster-sequences.js]
...
key.sequence('s i', function(evt, handler, sequence) {
console.log('You pressed s then i. If this were gmail, we would take you to your inbox.');
});
key.sequence('ctrl+c ctrl+v', function(evt, handler, sequence) {
console.log('You just copied and pasted... on windows... maybe... probably not...');
});
// obligatory konami code
key.sequence('up up down down left right left right b a', function(evt, handler, sequence) {
console.log('Works much better here than it did in contra.');
});
`
Pretty much identically to keymaster. key.sequence(shortcut, [, scope] handler). As with keymaster, scope defaults to 'all'.
The handler is passed the event and "handler" object that keymaster passes, along with a new sequence object. Though... the only thing useful in the sequence object is an array of all the keydown events.
* Injects itself into keymaster's window.key object. If you need to use noConflict, include sequences before you call noConflict.key.sequence('b shift')
* Modifier keys can't be used on their own. This means you can't do .key.sequence('ctrl+a b,command+a b')
* Only single shortcuts are currently supported. You can't do or key.sequence(['ctrl+a b','command+a b']). Support for adding this is pretty trivial, but I just haven't done it.key.deleteScope(scope)
* No unbinding... but when was the last time you cleaned up your event handlers? Workaround: You can use either or key.unbind(shortcut)` on all the individual shortcuts.
* Timeout between shortcuts is currently hardcoded to 1000ms.
* I've only run the tests on Chrome as of this minute. YMMV.
Includes two test files. The first is the standard keymaster tests, but with sequences inserted.
The second are a few sequences tests. More could definitely be added.
