Re: A little of coordination for Rosettacode

[bearophile]

Adam D. Ruppe:

and win the code golf every time! :P

Some Rosettacode D entries are a bit compressed, but that site is 
not for code golfing. It's just preferred to not write long 
programs, for several reasonable reasons.


code:
http://arsdnet.net/dcode/rpc-example.d

library:
https://github.com/adamdruppe/misc-stuff-including-D-programming-language-web-stuff/blob/master/rpc.d

I have reformatted your code a little for the D standard of 
Rosettacode (72 columns max, etc):
http://codepad.org/lAxAJwoG


With your code I have found a dmd compiler bug, are you able and 
willing to further reduce this?


import std.conv: to;
import std.traits: ParameterTypeTuple;
mixin template NetworkServer(Interface) {
  void callByNumber(int functionNumber, int sequenceNumber, 
const(ubyte)[] buffer) {
    string callCode() {
      string code;
      foreach(memIdx, member; __traits(allMembers, Interface)) {
        code ~= "\t\tcase " ~ to!string(memIdx + 1) ~ ":\n";
        alias mem = PassThrough!(__traits(getMember, Interface, 
member));
        foreach(i, arg; ParameterTypeTuple!mem) {
          auto istr = to!string(i);
          code ~= "\t\t\t" ~ arg.stringof ~ " arg" ~ istr ~ ";\n";
          code ~= "\t\t\tbuffer = deserializeInto(buffer, arg" ~ 
istr ~ ");\n";
        }
        code ~= "\t\tbreak;\n";
      }
      return code;
    }
    switch(functionNumber) {
      mixin(callCode());
    }
  }
}
template PassThrough(alias a) {
  alias PassThrough = a;
}
void deserializeInto(T)(inout(ubyte)[] buffer, ref T s) {
  s.length = 1;
}
mixin template NetworkClient(Interface) {
  private static void createClass() {}
  mixin(createClass());
}
interface ExampleNetworkFunctions {
  void sayHello(in string);
}
class ExampleServer : ExampleNetworkFunctions {
  override void sayHello(in string) {}
  mixin NetworkServer!ExampleNetworkFunctions;
}
void main() {}
