Sorry, I don't know why you may be having problems with that, but
might I suggest trying LuaCocoa to skip the middleman?


#!/Library/Frameworks/LuaCocoa.framework/Versions/Current/Tools/luacocoa
LuaCocoa.import("Cocoa")

function listfonts()
	local manager = NSFontManager:sharedFontManager()
	local font_families = manager:availableFontFamilies()

	for i=1, #font_families do
		print(font_families[i])
	end
end
listfonts()
