Questions about debug()

ant · October 12, 2015, 9:08am

I was happy to finally get the debug() method with Programmaticon V. I’m not a programmer, so it took some time to find my way with Chrome’s debug console and to realize that my debug messages would appear under Info.

So, I started with something simple:

friends = self.findFriends()
# then somewhere later
self.debug(friends)

This filled up the logs in no time, with error-like messages, and obviously hit the limit of 200 lines:

Is it a bug or a feature?

This is why I didn’t want to put in debug, because it’s totally janky: it goes to your JS console, isn’t very performant, and can’t easily serialize many types of objects across the web worker boundary. So if you end up seeing a problem like this, try to just debug a simpler type of value, like len(friends) or friends[0].id or something.

Later we will have a better debugging method.

Thanks, will experiment a bit more with it today.
