vJass compiling to Jass

After reading and searching thru the Scripts and Trigger section for sometime now, i noticed an interesting extension to JASS you guys are using called vJass. Wanting to learn it, i went thru the vJass for Spell Makers, Textmacros in vJass, How to Properly Inline Stuff, Create a New Object Type [vJass], and Scopes tutorial. I also read the readme.txt for JASSHelper.

During my reading and searching, i came upon this interesting thread: http://www.wc3campaigns.net/showpost...67&postcount=4.

Here are my questions:

• What is the theory or idea behind vJass compiling into Jass? In other words, how does vJass work? I'm not asking how to use vJass.
  
  What does the s__structdata__allocate() function look like?
  Why are integer si__structdata_F=0 and integer si__structdata_I=0 not used?
  
  
• Can you guys give me more example similar to Malf's vJass compile example, so i can analyze it?

To me, vJass's struct looks like a clever way to use globals to pass multiple data under a single variable type to another function. So, i'm curious, how do you guys do it from Jass?

The jass code that the guy posted is incomplete where he put the ... in his example.

You can check out easily how it works by writing a small vJass script, compiling it with JassHelper and then opening war3map.j (which then contains the compiled jass) in a text editor.

Thanks! just what i was looking for.
Funny, making a test vJass Script didn't seem to work the first time i tried it..., but then again, that was with a certain third party program.

The basic idea is you have parallel arrays which you parcel out an index at a time. To recycle indices, you push them onto a stack. When you allocate a new struct you first try to pop that stack before creating a new index.

well but that is just for struct. :P vJass is a tool for the lazy jassers :P But also keep things more readable and organized

structs and global declaration are nice ^^ (structs allows to short the code (while typing it) and it's imho very handy)
