[erlang-questions] Erlang introspection

[Andrew Stone]

If both sides are erlang you can send the actual fun(), otherwise, on the receiving end you can do list_to_atom on the function name and then call the function with the arguments. For instance you could do something like this.

you've received a string "fun_name", with arguments A, B, C.

Func = list_to_atom("fun_name"),
Func(A,B,C).

Of course you need the actual function to exist and the parameters to be valid. And IMHO, you also really don't want to be doing stuff like this over a network unless you are VERY careful.

Subject: [erlang-questions] Erlang introspection


I'm trying to find 
information about erlangs support for introspection. I've got a program that 
receives and function name and arguments through a socket and I'd like to use 
this information to make a function call on the module that receives it. Can 
anyone suggest a good starting point for finding out how to do 
this?
 
Thanks
 
Matt
