What is vrJASS?
A just-for-fun programming language which compiles down to JASS (Warcraft 3). It aims to improve and replace the beloved vJASS.

What? x2
An update to vJASS which tries to solve its flaws.

I want to try it! - I need a manual
https://github.com/Ruk33/vrJASS/wiki

Last version
https://github.com/Ruk33/vrJASS/releases

Like SublimeText?
Here, a linter: https://github.com/Ruk33/SublimeLinter-contrib-vrjasslint

TODOs

80%-100% (I'm planning not to implement a few features, like function interfaces, but if anyone can/want-to code it, will be welcome) compatibility with vJASS
Improve debug messages
Fix (module) initializations (implemented as abstract classes)
Improve OOP (type-safety, attributes initialization, etc.)
Anonymous functions
Free variable definition
Add operators +=, -=, *=, /=
Improve/add loops
Null/Empty string/0 Conditional (null->false, "" -> false, 0 -> false)
~~Auto-null local handle variables~~ Optimizers do this already
~~Return array~~ Simply use structs
Allow end as alternative to endfunction, endmethod, endloop, etc.
~~Hooks (before/after)?~~ Delegated to cJASS
~~Alternative C-like syntax~~ Delegated to cJASS

Green -> Done

When is it gonna be ready?
It already is on an stable version!

Where can I see the progress/code?

How can I help you?
If you know Java or Antlr4 you can check the repository and send me pull requests (don't worry if you don't know too much about them, I'm new too!). If you don't know these languages, let me know your suggestions, I'm open to them :)

So there will be no changes for the final-user (you), it will be like coding with the actual vJASS in my current setup in Newgen without any weird stuff, right?
Kinda. Yes, it is gonna be the same syntax, same features (excepting just a few that no one uses) but with a few and hopefully useful new features like better error messages, free variable definition (not only at the beginning), new loops, etc..

Few examples
Anonymous functions
Code: jass
1. call TimerStart(..., function
2. local timer expiredTimer = GetExpiredTimer()
3. // ...
4. endfunction)
Free variable definition
Code: jass
1. function foo takes nothing returns nothing
2. call TimerStart(...)
4. if (...) then
5. // ...
6. endif
8. local unit bar = CreateUnit(...)
9. endfunction
Operators +=, -=, *=, /=
Code: jass
1. local integer i = 5
3. set i += 5 // same as set i = i + 5
4. set i -= 5 // same as set i = i - 5
5. set i *= 5 // same as set i = i * 5
6. set i /= 5 // same as set i = i / 5
Improved loops
Code: jass
1. while (true)
2. if (shouldSkipThisIteration) then
3. continue
4. endif
6. // ...
8. if (isOver) then
9. break // same as exitwhen true
10. endif
11. endwhile
Null/0 conditional
Code: jass
1. local unit u = null
3. if (u) then
4. // unit isn't null
5. else
6. // unit is null
7. endif
9. local MyCustomStruct instance = ...
11. if (instance) then
12. // instance exists (allocated)
13. else
14. // instance does not exists (not-allocated)
15. endif
