Use . in a method registered with LuaInterface

Question

I'm integrating LuaInterface into a c# program using LuaInterface. I want to be able to write scripts that can access C# methods in the program.

The methods that it is accessing are in separate "subsystems" and I wanted to have the Lua method define the subsystem, then the method using . as a separator. e.g. SubsystemName.MethodName

but this throws an exception when I try to register the method. I've changed it to _ and it works perfectly. Is there anyway to get it working with .? The program has other interfaces for calling these methods like JSON-RPC via HTTP and these use the . notation so would like it to be consistent.

You can define your methods using _ as a separator in your .NET code, e.g. SubsystemName_MethodName. Then create a simple Lua module, that does roughly the following:

local YourClass = luanet.import_type("Your.Binding.Class")

SubsystemName = {} -- create a global table
SubsystemName.MethodName = YourClass.SubsystemName_MethodName

This will allow you to use SubsystemName.MethodName in Lua.

Instead of doing it manually (which can be tedious and error-prone), you can use a code generator that creates the Lua code from a list of classes/methods.
