Macro __CALLER__ q

[Alex Shneyderman]

I have a macro that I needs to recognize  __CALLER__ vars.

so when I do - 

   def idle(%{"timeout" => t} = state) do

      ereceive do 

        ....

      end

   end

erceive is the macro and it needs to know state and not t. So when I do __CALLER__.vars I am getting [state: nil, t: nil]. There is  no information on the exact nature of state or t. Is there a simple way to differentiate between the arguments without overwriting def ?

Cheers,

Alex.

How would you like to differentiate the variables? Can you explain a bit more what the ereceive macro does and how it wants to use the variables?

Would it be possible to pass the variables the macro needs to it? Like this: ereceive state do ... end.
