EasyLua is an easy to integrate and easy to use library for bridging Obj-C and Lua. Our goal was to make a library which is easy to call into lua and out to iOS with no knowlege required of how the lua c bridge worked. An emphesis was placed on also making the lua code readable when using objective-c classes
No initialization is needed on the iOS side. Examples within objective-c:
[[EasyLua sharedEasyLua] runLuaString:@"print(\"Hello World\")"];
[[EasyLua sharedEasyLua] runLuaBundleFile:@"MyCode.lua"]
All Objective-c classes in the binary are available for use in lua. Some Example lua code:
instance = MyClassName('alloc')('init')
instance('methodName:', 'param_1')
instance('methodName:param2name:', 'param_1', 'param_2')
When calling methods, Lua stirngs are automatically converted into NSStrings and numebrs, if needed will be converted to NSNumbers. Additionally, NSObject are wrapped and unwrapped as needed when being sent between the two environments
Dictionaries can also be used similar to how they are used in Objective-C:
new_dict = NSMutableDictionary('alloc')('init')
new_dict['ReturnKey'] = 'ReturnValue'
Additionally, tables will be converted into either NSArrays or NSDictionaries when returned or called as parameters to an Objective-C method.
EasyLua was originally derived from Lua-Objective-C Bridge. Special thanks to the original author Toru Hisai!
Currently, calling a method such as this will fail:
NSString('alloc')('init')
This is because strings are converted into lua strings right away, so when you all init, it does not know what to do. This can be fixed in the future but should generally not be needed as you can simply use lua string.
