LiveCoder.net = A simple browser environment
for coding live javascript
Language Extensions
vars._ A place to put persistent data
once._ A place to put functions that run once
always._ A place to put functions that run continuously
cached(f)(-) Caches value of f applied to JSON'able arguments
(useful for expensive tasks like audio synthesis)
clear() Clears vars, once, always, cache, setTimeouts, canvas
using(url) Loads & caches a remote script (useful for libraries)
Coding Tools
help(-) Looks inside any object/function (great for hacking :)
print(-), Print messages to log area
error(-)
assert(-,-) assert(value,message) throws an error if value is false
(see help(assert) for details & other assertions)

mouseX, Current mouse coordinates in pixels
mouseY
Audio - using HTML5 audio
play(-) Plays a uri from encodeWav/tone/noise/speech or the web

livecoder.net's Issues
Select, move, click causes code region to jump
Select some code region, move it to another place (drag & drop), and click on the code region.
This causes the code region to jump in Chrome. I'm using Chrome dev v21.
Firefox seemed to work fine.
Long update functions
If you accidentally type something that causes the update functions to take too much time it becomes very hard to clear the active code, due to automatic saving and slow responsiveness. It might be a good idea to set some time-limit to the functions, if they run over the time, then stop running them.

Audio induces browser crash in chrome/linux
Kassen writes:
Both rhythmical examples, the "simple" and the "Markov" one crash my
browser after -say- 20 seconds or so. I was testing with Chromium and
am running Linux. I could give you more specs or run tests if you tell
me what you need. Chromium said "Oh, Snap".
