In the last couple of months, we have reached over 100 stars on GitHub, updated our homepage, and as usual caught up with support for Warcraft 3 patches 1.30.2 and beyond.

Tool updates

• The wurst family of tools now supports the latest battle.net stable patch (1.30.2).
• The wurst language was updated to allow classes to contain tuple array members.
• Improper usage of generic types now throws proper compilation errors
• Attempting to access objects that are known to have already been destroyed now fails at compile time.
• Fixed a bug in local optimizations which caused unexpected behavior.
• Wurst no longer requires JavaFX, which enables wurst builds in a wider range of java distributions.

Standard library highlights

• Merged over a dozen awesome pull requests.
• Added DummyCaster in addition to InstantDummyCaster for channel based spells, and spells with delayed effects.
• Fixed some critical bugs in HashList, HashSet and Knockback3D.
• We have newly-added code conventions - go align your formatting!
• We have begun writing in-depth package documentation

Spotlight: Stack traces

Did you know that WurstScript generates stack traces for calls of error(string msg) from the ErrorHandling package? You might have seen this from a wurst error before - it will show you which lines in your code were executed in what order before the error occured.

Take a look at this example:

package Test
import ErrorHandling

function foo()
	new A().bar()

class A

	function bar()
		error("This is an error message")

init
	foo()

It produces the following stacktrace ingame:

As you can see the most recent line comes at the top and the oldest at the bottom. Stack traces help tremendously with debugging errors, as it gives you a history of what happened before the error. Naturally they cause quite a performance hit. If you verified your map working well, you can disable them via the corresponding runarg -stacktraces, which is enabled by default.
