Scratch compiler beta test

@procd You should put this project on Github or Bitbucket. The community can point out issues with the compiler, and help fix the issues as well.

Please read the whole first page of this thread, it's not going to be released until beta testing is finished.

Could you please show the source code, or tell how do you extract blocks from sb2 file? I would like to write my compiler that would produce a program for a microcontroller.

This should help?.

ScratchVaders or Galaga?
Maybe Eliza can help you decide?

That was what I used. Feel free to ask any questions, but it's a very good reference.

Thank you for the link! That will be useful.

Hey, I'd like you to compile this thing I made, quickly. It's called Bolt Chopper, and you are a chopper that fires bolts at an enemy. I made it. Thanks!

I don't think it's available to the public yet. (I wish it was.)

If you check out the beta test project then you'll see that I'm in the middle of some changes at the moment trying to get the graphics effects converted to hlsl (high level shader language). Hopefully be out the woods fairly soon then I'll compile your project for you.

I'll try and compile any of your projects if you request it. Now is not such a good time if you read the previous comment though!

I'll tell you if I want any! I just liking having it myself, so that I can compile, make changes, compile again, etcetera.

What if I need to sell my project if it's converted to EXE with this one?
And it's not a true beta test because a beta test is like a public test, not a private test.

There can be private betas. I'm in the Distance private beta. It's upto the creator/publisher/etc. if they want their project to be public or not.

No I don't make projects anymore. I left some time ago.
I only check the forums every now and then, but other than that consider me retired.

I have made 2950+ posts / contributed to 2238+ topics

I know you asked this quite a long time ago, but if you're still interested in seeing (roughly) how a scratch parser works, I just put up my prototype scratch to C code at http://www.gtoal.com/scratch/sb2c/

It's not a working system but there's enough there to learn how to unparse the json file. (Which in computer science terms is effectively an AST: Abstract Syntax Tree, although to be more precise it's more of a concrete syntax tree than an abstract one…)

Technical question, what is the performance compared to good ol' JIT compiled scratch?
As in, does the compiler respect the delay inserted in the broadcast and loop blocks, or does it plow right through it and runs at full speed with no stepping?
(either way, you could add that as a setting)

Pondering what to work on.

The compiler runs as much like scratch as possible so respects loops, however like scratch can also be run in turbo mode to ignore those conditions.
Performance wise it's quicker in pretty much all areas bar one and that is the touching blocks. I have a studio with some of the compiled projects so you can try them out and compare.
Being .NET it's JIT too!
