Jass3?

[Aniki]

After dumping the strings from the game's executable (x86_64/Warcraft III.exe, version 1.31) one can find references to "jass3". From these strings it seems that Jass3 is very similar to vJass, having: libarries, modules, structs, interfaces, scopes, textmacros, delegates and operator overloading. I don't know if there's a way to tell the game to interpret the mapscript as Jass3 and not Jass2/Lua.

These strings seem to be related to "jass3":

out of dynamic memory in jass3_create_buffer()
out of dynamic memory in jass3ensure_buffer_stack()
out of dynamic memory in jass3_scan_buffer()
out of dynamic memory in jass3_scan_bytes()
bad buffer in jass3_scan_bytes()
jass3set_lineno called with no buffer
jass3set_column called with no buffer

That's almost certainly just their codename for "vJass". It doesn't have any features that vJass itself doesn't already include.

People have found references to jass3 before by looking through the executable, but this is probably the most detailed information about it out there. Seeing what it contains, JASS3 almost seems like a it'll be a vJASS parser. But it's quite possible that it's a new language and they just want it to be as similar to jass2/vjass as possible, to make porting old maps easier. Though I really wonder what the point of going through all this effort is, since Lua can now be used (and so can many other languages, via transpilers).

Imagine if JASS and Lua could coexist in the same map, with JASS compiling into Lua when the map is saved or loaded.

A vJASS to Lua transpiler would definitely be interesting... they already had a JASS one in the Reforged BETA, so maybe that may be what jass3 is?

I really can't imagine this engine will see future patches to bring to light unused features. There is not that kind of business plan with Reforged. They did not open up Microtransactions to sell some of the skins that the game *looks like* they intended to sell. As a user, you could not help financially support Reforged if you wanted to.

I do not think these constructs, if they existed unused in the game, will ever become used.
