Pinty

Pinty is a little prototype where I investigated the feasibility of an Apache Spark-like system in C++.

pinty.cc serves as a little demo. It defines f() like this:

Function<int(int)> f(int i) {
  auto x = [=](int y){ return y + i; };
  return x;
}

So f(N) is an int to int function that adds N to a number.

$ ./run.mac.sh
To save f(N):
  ./pinty save <N>
To load and call a function:
  ./pinty call <fn> <M>
$ ./run.mac.sh save 100
f(100): b01200000100000064000000
$ ./run.mac.sh call b01200000100000064000000 5
b01200000100000064000000(5): 105

The closure is serialized as b01200000100000064000000. You can see 64 (decimal 100) in the serialized form. When deserialized it still adds 100 to a number. Mission accomplished.
