[DM-dev] cool idea for an extendible file format

[Stephan B. <st...@wa...>]

Pete, I think I just had one of the most brilliant ideas I've ever had...

I just completely solved all problems regarding file parsing and how to get 
the data to the dungeon in not only a simple way, but an extendable and 
easily maintanably way.


I can't write the code here because I don't know the syntax for function 
pointers (and too tired to look it up), but it'd go like this:

Create a map with string keys and function pointer values. The functions must 
match this signature:

  void funcname( string input_data, DMGrid *grid );

input_data == the string information parsed from the saved data. It is sent 
to the object in it's raw, unparsed format (only the value, not the key). 
This allows the registered function to do whatever it wants to. This makes 
the file format extremely extendable:

1) register and write your function.
2) add function to pointer map.
3) add lines like this in your input files:
  mynewtypeofdungeonobject=custom|parsing|is|possible

The callback function sends the parsed data, and a grid to render the object 
to. Generic rendering support is already in DungeonElement, so can be re-used 
by these callbacks.

got that?
