This is a small library to organize RPC over TCP/IP, using YAML as data serialization format.
RPC server should supply a set of "RPC methods", which are simply functions ::
a -> IO b, `a' and 'b' should be of class IsYamlObject. This class guarantees
that values of given type can be serialized to YAML and de-serialized.
Network.YAML.Instances module provides some instances declaration for this
typeclass. Moreover, Network.YAML.Derive module contains (TemplateHaskell)
function deriveIsYamlObject, which will help you to declare `instance
IsYamlObject ...' for almost any ADT.
RPC-client calls RPC-methods usually using one of two ways. First is to use `call' (or `callDynamic') function from Network.YAML.Caller module. One need to give method name as it's parameter. Second way is to use (TemplateHaskell-) function `remote' from Network.YAML.WrapMethods module to declare wrapper functions for RPC-methods. These wrappers will have same names as source functions, and almost same behaivour. Single difference is that wrappers require pair: (RPC-server host name, port number) as their first argument.
