print()?

print() won't work for me. it just prints nothing. both in the IDE and when exported to a web page.
printIn() returns the error: Cannot find method "printIn(java.lang.String)"
i wouldn't surprised one bit if it were something i was doing. i don't know much about java.

are you on mac or pc? which rev of p5 are you using?
printIn should be println, short for "Print Line"
also what are you trying to print?

yup. print() has a bug on 0046 as reported by mike davis. go around this by following print() with println(). applet won't return anything unless you have a console window.

hm, all it's doing in this case is calling java's System.out.println and System.out.print..
print() style functions in most apps/apis/languages generally don't show their output right away unless the buffer is flushed. a new line (or some higher number of characters) most often flushes the buffer, forcing the output to be updated. this is because flushing on every print() tends to be very slow.
that said, i think it may make sense to flush on print() for p5, since print() is really only used as a debugging tool (speed not an issue) and it makes more sense for it to behave 'as expected' (flushing/updating every time) than to make people learn this bit of trivia just to get messages printing to the console. if you guys were thrown off by it, it's more than likely that some other folks will be too.
thanks for the report..
