`region-dump` now requires a `chunks` directory for output instead of `stdout`? #41

Closed rjp closed 2 years ago

rjp commented 2 years ago

I used to use region-dump to output a region to stdout (for various analysis purposes) but that seems to have changed (somewhere around 2021-07-05?) and it now dumps the region into a bunch of files in a chunks folder?

Any chance we can have the old stdout behaviour back? I can't revert to the old version because my worlds are now 1.18 but the new chunks folder approach doesn't really work for analysis.

Hey there, this can definitely be done. The region-dump executable is pretty simple.

Was the behaviour you wanted just dumping out the chunks one after the other in Rust's debug format? Is there a better format you'd rather it spit out to? Converting it to json should be possible for example.

Yeah, just all the chunks in the region like it used to do.

JSON would be perfect - I did have a stab at converting the Rust debug format into JSON but my Rust is non-existent and trying to convert it post-hoc turned into a nightmare.

Thanks!

Latest fasnbt-tools should have you covered:

region-dump <file> # all chunks to stdout in Rust debug format
region-dump -f json <file> # all chunks to stdout in JSON, one line per chunk.
region-dump -f json -o chunks <file> # chunk per file in JSON
region-dump -f nbt -o chunks <file> # chunk per file in original NBT

You can also specify json-pretty and rust-pretty to get pretty-print versions. The exact format might have changed since you last tried since I had to change how the deserialiser works prior to 1.0.

Let me know if this works or not!
