Kind of..fail...Edit: Ahh, Struct Iterating. Sorry, I can't. Because the JassNewGen doesn't support modules yet, and the JassHelper doesn't support grimoire.
But...
Wait, I can inline it by hand.
You know, jasshelper is called by grimoire and so, jasshelper dont have to support grimoire. it's actually reversed. and, with the right patch or the right exe (worldedit 1.21b.exe) it works as always. (dont you use jasshelper atm?!)
Also, have a look at the jasshelper reame:
Jass New Gen Pack already comes with JassHelper, although it might not come with the most recent version, in order to update you can simply copy executable\jasshelper.exe to the NewGen Pack"s jasshelper subfolder. You may also update the JassHelper documentation if you wish
