An ongoing project to catalogue all of these sneaky, hidden, bleeding edge selectors as I prepare my JSConf EU 2012 talk.

Everything is broken up by tag, but within each the selectors aren't particularly ordered.

I have not tested/verified all of these. Have I missed some or got it wrong? Let me know. - A

A friendly reminder that you may need to set this property on your target/selected element to get the styling results you want:

-webkit-appearance:none;

This information applies to the PICO-8 0.1.6 release.

This document is here to help folks with a proficiency in Lua understand the limitations and discrepencies between Lua and PICO-8's Lua.

You can always view the manual or yellowafterlife's extended 0.1.1 manual.

General

• anything written in uppercase the PICO-8 editor or .p8 is made lowercase by the editor. → editing the .p8 file directly can work
• print(function() end) outputs the string function instead of the string function: 0x0000000.

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

Code is clean if it can be understood easily – by everyone on the team. Clean code can be read and enhanced by a developer other than its original author. With understandability comes readability, changeability, extensibility and maintainability.

General rules

1. Follow standard conventions.
2. Keep it simple stupid. Simpler is always better. Reduce complexity as much as possible.
3. Boy scout rule. Leave the campground cleaner than you found it.
4. Always find root cause. Always look for the root cause of a problem.
