[DGD] getting started with DGD

[Jeff Moore]

Hello,

Its been about 8 years since I've done anything in LPC.  I just ran 
across DGD the other day and it looked interesting so I started playing 
around with it.

I've taken a look a the mudlibs available and started playing around 
with the kernel mudlib.

I was re-organizing user.c and found that I was getting a seg fault 
when executing the line:

connect(previous_object());

It seems the error occurred after I arranged things so that 
previous_object() wasn't the connection any more.  I think I was doing 
the equivalent of:

connect(this_object());

This was not the right thing to do, but a seg fault is still probably 
not a good thing.

I also have some questions about DGD that I could not find the answer 
to in the various documentation.  Its probably there.  sorry if these 
are FAQs.

First, I've read a little about this idea of re-compiling objects on 
the fly.  To test this, I was re-compiling user.c, but I would get 
various errors as if the objects that user.c inherits from were out of 
sync.  I could solve the problem by inserting prototypes that would 
normally be unnecessary.  In fact, if I shutdown the mud and brought it 
back up, then I could take the prototypes out and everything would 
compile fine.  Is the kernel mud not set up for this? Am I doing 
something wrong? Is this what the objectd code that I ran across does?  
If so, why is this not in the kernel?

Which function searches one string for another or find the position of 
an element in an array?

Is there a way to get a slice based on the end of a string, but not 
using strlen.  something like [0..<1]?

Is it possible to move the /System directory out of the USR directory 
without changing the kernel?

Is it possible to listen to port 80 for an in game http server as well 
as to listen for the telnet port?

How do you create functions that every object can call without an 
explicit include or inherit without modifying the kernal auto object?

I guess thats it for now.  :)

thanks,
Jeff

(PS.  I'm running 1.2.84)
