Why?

This module provides code support for JASS to be used in Ice Sickle. It's main code is the Antlr4 grammar definition. Since JASS is the native scripting language for WarCraft III, no transpilation is needed, so code remains untouched by the transpiler method.

Language Overview

JASS (Just Another Scripting Syntax) is a very simple scripting language by Blizzard Entertainment. This is not meant to be a guide to JASS coding, but rather just a quick glimpse of the core of the language.

Functions
``
function MyFunction takes unit u, region r returns boolean
... (statements)
return false
endfunction

call MyFunction(...)
`

Local variables
`
local unit u = null
set u = ...
`

Globals
`
globals
trigger t = null
region gg_my_region = ...
endglobals
`

Logical conditions
`
if life == 55 then
call Hello(7, 22)
elseif not udg_True then
call ok(myVar, 4, "hello")
elseif (true or true) and false then
call Strange("helloWorld", 54, false)
elseif udg_IsTriggerEnabled then
call ThisIsTrue(true)
else
call Yay()
endif
`

Loops
`
// This is the only type of loop in JASS
// There are no "for" or "while" loops
loop
set i = i - 1
call SetPlayerAbilityAvailable(Player(i), udg_SpellDamageAbility, false)
exitwhen i == 0
endloop
