feature request: with-sketch in clojure.

[magnetophon]

I'm a total clojure newbie,but already love quil

Afaict there is no way of controlling sketch outside sketch code.
See this.

I'd like to be able to have overtone events trigger drawing.

Actually, there is a way. You can use

(quil.applet/with-applet my-sketch
  (ellipse 100 100 100 100))

It's kinda "internal" because it's not in quil.core but should work. And I guess it makes sense to make it public as with-sketch. Would you be interested in adding it?

@nbeloglazov
Thanks, I'll try that.
What do you mean by ''Would you be interested in adding it?''

[nbeloglazov]

I mean that quil.applet/with-applet is "private" I think it should be public by adding it to quil.core/with-sketch. This way with-sketch is going to work both in clojure and clojurescript.

@nbeloglazov Sounds good to me!

I tried to implement with-sketch for clojure but failed. Nothing was drawn on a sketch. I believe Processing doesn't support drawing outside of "draw" function. After draw is called processing disposes graphics object and if we try to draw on it from another thread using with-sketch nothing will happen. It silently ignores all draw operations.

Some other lifecycle functions like start-loop and no-loop might still work but it doesn't feel right to support with-sketch if only limited number of functions are going to work. I'm closing this issue as "not feasible". If anyone has ideas how to fix it - feel free to reopen.

[nbeloglazov]

So the only possible way from some other code (like overtone) to write something is to save data into an atom and have sketch draw function read this data and draw. There might be small lag between overtone updating atom and sketch drawing it, but given that FPS is pretty high 30-60, the lag should be hardly noticeable.

Thanks for looking in to it, and for providing a workaround.
