Version 2.99.013 at http://byob.berkeley.edu  with a debugger!  See the release notes (there's a link) for details.  Yay!

P.S. Jens will be off the net on vacation for two weeks.

OMG!!! THAT'S AWESOME!!!! I just put a list block in the debug block and I already know what it's for!

Can i suggest adding help file for the new blocks, i don't have a clue what the debug blocks are supposed to be used for. Either that or a tutorial.

What we have right now is Jens's release notes.  I agree that more documentation is needed, but I got the image from Jens last night in the middle of putting the recursion tutorial together, and by the time that was done it was after midnight!

Help screens for all the BYOB blocks are the next thing on my agenda, because they're (I think) the biggest obstacle to declaring a beta release.

Help!

When I try to run tutorial 3a or 3b from the Scratch site, it displays and fills up the "Loading..." progress bar, then just sits there forever.  I don't have this problem with the other tutorials.  I've tried it on three computers and five browsers.  I tried looking through the Troubleshooting forum but there are 97 pages of listings and I gave up in despair.  But I figure one of you will know the solution!    Thanks.

It's working for me though (both) - so I don't know what you're doing wrong xD. Probably something with your java player perhaps? I really have no idea 

Oh. My. GOSH!!!! BYOB 2.99.013 is beyond awesome!!!!

When they are executed they will bring up the debugger, that's my understanding. I'm not sure what the reporter is for, or why it takes an argument.

Personally I'd prefer to be able to trace output to some sort of console.

Let's say you've written a reporter FOO and it's reporting the wrong value to something else.  Maybe the entire command is
    SAY[ [FOO 4 5 6] + <3>]

So you make it
    SAY [ [DEBUG [FOO 4 5 6]] + <3>]
and then you enter the debugger just as FOO starts and again when it reports a value.

My idea was that you should be able to attach breakpoints to a block in a script the way you can comments, but Jens didn't want to mess with the UI and with the evaluator as that would require, so this is the compromise. 

Personally I'd prefer to be able to trace output to some sort of console.

Yes, definitely.  I'm sure we'll do that.  It's really orthogonal to debugging; there are lots of reasons you'd like a text buffer.  But meanwhile, may I suggest logging the output to a list?  Just ADD <whatever> TO <log-list>.

No, I mean I don't know how to use the debugger, I know how to get to it.

Two things: (1) while the script is paused, you can use the regular Scratch mechanisms to examine variables, and the BYOB edit menu option to look inside blocks.  (2) the buttons on the debugger window itself allow single stepping and examining block-local variables.  Jens's release notes have a little more detail.

Thanks, this should help alot.

Umm, btw, I'm assuming this means you're stuck on PREDECESSOR, right?  If you're stuck on understanding the basics, ask a question.  (Well, you can ask about PREDECESSOR, too, but I'm happy to let you struggle with it as long as you want.)

I'd prefer to struggle, thanks!

Just got BYOB 2.99.013 - the pause button is amazing! 

Wow, that's neat!

With the pause button, their should be a pause block and a resume block.

Good idea!
