printing out error messages in the javascript version of processing -

To reduce a long story, I have to use the class processing and I am completely blinded by IDA completely unrecoverable. That's why I use the JavaScript version of processing to create a page, and a specific person with me describes my output. Unfortunately, if there are errors in code then the page appears blank and there is no explanation for what is wrong. Looking at the following code, I'm getting a way to the JavaScript version of processing, because I forgot that I have a syntax error;)

 zero setup () {size (500, 500); } Zero line () {line (250, 200, 250, 40} 

well for debugging From (when code compiles) you can use the println () command.

I am using the processing for 2 months and I have a single problem and can not find any solution for this. / P>

Here I do not use almost any processing for what I have seen or how to use it. You can use it for processing forums You can try, you will usually get the answer within one or two days.

Sorry to not be able to help. I see that the only solution is if you Use your PDE (Processing Development Environment) and compile it.

EDIT: Experience asking previous processing questions, who do not have too much PPL in search of your question: (< / P>
