PICO-8 size optimization stuff for tweetcarts

Here are some simple ways to make your PICO-8 code fit in ~~140~~ 280 characters (as in the #tweetjam #tweetcart craze). I did not invent these, I merely observed and collected them from the tweetjam thread.

LUA syntax stuff

Use single character variable names
Use x=.1 and x=.023, not x=0.1 or x=0.023
x=1/3 is shorter than x=.3333
You don't need to separate everything with spaces or write them on their own lines, e.g. circ(x,y,1)pset(z,q,7) works just as well

Sort object properties by value (values are text)

I have following object:

var cities={10:'Tashkent', 14:'Karakalpakiya', 16:'Andijan'};

I want sort it by city names, so after sort it should be:

var cities={16:'Andijan', 14:'Karakalpakiya', 10:'Tashkent'};

But I can't sort object properties, instead can convert object into array, then sort items.

jquery.scrollLock.js

Useful for when a blocking user experience is needed (in my case, didn't want people unwittingly loosing their place by scrolling while a modal required their attention): $.scrollLock() locks the body in place, preventing scroll until it is unlocked.

// Locks the page if it's currently unlocked
$.scrollLock();

// ...or vice versa
