Last night I was thinking about live coding and also about how Java has reflection built into it. So, even though there is a forum topic about live coding with Processing, I decided to code up a simple sketch that evaluates a single line of Processing code and continually draws the result. There are drawbacks, of course, namely that you can’t specify fills or stroke colors and you can’t change the background color. However, in the next iteration I plan to ditch the textfield being used and instead use a textbox that will be evaluated in draw without the user having to press the enter key. Probably I should check out the tools talked about in the forum topic, but I like the idea of having a sketch that is itself an interpreter, rather than using a more generic tool for evaluating Java. Then again, I may discover that building something even marginally useful is more complicated than I care to implement, at which point I will probably turn to an existing tool. In the meantime, please enjoy:
