What's the difference between world.dat and world.sav?
« on: December 02, 2020, 09:41:47 am »
Some saves seem to have a world.dat, and some saves a world.sav? Is there any difference between them? I'm making a Python 3 script for extracting the generated raws (https://dffd.bay12games.com/submit.php?action=edit&eid=15321), and trying to figure out if it's something I can just ignore.

The difference is that "world.sav" has either a Fortress or Adventurer in progress, while "world.dat" is ready to start a new game.

Incidentally, I've already written a Perl script (and even a PHP script) to extract generated raws, in case you want to double-check your implementation and make it compatible with as many versions as you need.

It's amazing how dwarves can make a stack of bones completely waterproof and magmaproof.

It's amazing how they can make an entire floodgate out of the bones of 2 cats.

Huh, that's a funny difference. Should work the same for me though, if that's all it is. Thanks! :)

Figures someone made something like this before, and a prettier solution at that, even able to read compressed saves. Mine just looks through the uncompressed save, pretending it's a text file, and then outputs anything looking like an object (all the square brackets following each "[OBJECT:"). Then it discards/ignores all junk data it gets by reading the rest of the save, which I'm sure is A-OK. The upside is that the same version I made to work with 0.47.04 also worked with 0.31.06 without any changes, so I don't think I have to bother with compatibility issues.
