LS97, how's the Script-to-Squeak-converter working out?

*blushes from shame*
Ehm, I kinda forgot about that right now, because I'm working on the API2 project with sparks and fg123, but I will continue it as soon as I can!
Sorry 

No problem! If you look at the pile of unfinished stuff I have, you may faint.

Hehe. I have more. :3

How do you know? 
I have a ton as well.

On topic, i was thinking of making a reverse thingy of this that goes into 2.0 code. Probably web based, just like 2.0 itself. It'll still need some work on the user's part though.

Very cool!  I'd been thinking of something like this from the time of the [scratchblocks] format update.

Would it be possible to generate scripts from [scratchblocks] code on the clipboard?  Maybe with a right click on the back of the scripting pane, and selecting "import scratchblocks from clipboard?" I'm not really sure what sort of coding this would require.   What does the exporter see that it is able to turn into [scratchblocks] code?  Shouldn't it be relatively simple to do that the other way around as well?

I have some large projects with massive scripts - especially those attempting to be 1s1s - and the lag between each action can be huge! If I could type in scratchblocks and import that after, that would help my boring "my stuff" page out a ton!

What are lex and yacc? I've never heard of those.

Wait...  Does that mean you have python code that I could use to turn scratchblocks code back into scripts?

Lex is a tokenizer, and yacc is a parser -- they're libraries used to parse formal languages (like C and Python, I think).

Indeed! Check it out here.

it does a lot of things that are quite hard to reverse. Take booleans: the < meaning "less than" looks a lot like the start of another boolean block... And things like the "length of" (string/list) and "of" (math function/attribute of sprite) are hard to tell apart. 

Well, the scratchblocks parser of the forums can tell all of them apart, so it's bound to be possible. But one thing is just parsing the appearance of the blocks and displaying them on a forum, and another is actually recognising them and giving them the right selectors and arguments 

That's absolutely true    JSO was saying somewhere that he doesn't actually validate the scripts at all — you don't need to when you're only displaying them.

My basic strategy was to parse them into parts (word / inserts / embedded reporters); filter them to separate the words and the inserts; look up the block by its text using the words; and then verify the inserts against the block argument flags ("%b", "%n", etc) where there are multiple choices of block to choose from. The "of" block is tricky when the second argument is a reporter: so I also have a list of valid arguments to the "%f" (math function) block. Should give you some idea... 

That's very clever 
I don't think I will take on such a big project now, especially since we're transitioning to 2.0 so relatively soon. I did make a blocks2squeak in the meantime...   see other advanced topics thread by me

blocks2squeak sounds cool. How do you deal with "wait until", "ask" blocks, and the like?

They are parsed especially, and most of them work well, but some are ignored on purpose because it wouldn't really make sense to have them in a single threaded method.

cool thing!

How do I use it after it's been installed?

I'm having the same problem.

when gf clicked

say [Hello!] for (2) secs

broadcast [how to use scratch v] and wait

say [Scratch On!] for (2) secs

forever  

play sound [Ending Music v] until done

end

for people who have problems using it, copy it into notepad and save it as

"blocks.cs"

Somewhere in an easy-to remember place.
I couldn't select "cs" so I had to type it in manually.

Also, "Browse for the downloaded file" is a bit hard to explain; in the top bar navigate, not the lower one.

Its not downlaoding
I press the link and all it says is a bunch of codes 

Do you mind if I use it in my Scratch mod?
