This mini project started when I realized that the GDB remote debugging protocol allowed the remote host complete control over what was sent back. There was no reason it had to actually be connected to a process. So why not try to make an oldschool adventure game out of it.

This is from memory, so excuse me if I get some bits wrong. When the program is executed it creates a GDB server on port 1234 (see GDBStub.hs). From gdb you then connect to the server:

(gdb) target remote localhost:1234

At this point you're in the game. So far the only operation that seems to be implemented is printing symbols. For example, try asking for a description of an item:

(gdb) print lamp

Or ask for a description about the current room:

(gdb) print here

I believe basic support for moving between rooms is there, but I don't quite remember how that works.

See GDBStubHandlers.hs which is where the commands coming from the client should be handled. Right now we only handle 'm' (memory) but handlers can easily be added for the other operations.
