README.md

`lihzahrd`

A Terraria 1.3.5.3 world parser in Python.

You can use this package to get programmer-friendly data from a Terraria world!

Install with:

pip install lihzahrd

Usage

You can open a world file and get a World object by calling:

import lihzahrd
world = lihzahrd.World.create_from_file("filename.wld")

It will take a while to process: a small Terraria world contains more than 5 million tiles!

Once you have a World object, you can use all data present in the save file by accessing its attributes.

Documentation

The documentation is available here.

It's a bit messy and incomplete, as I still have not figured out the meaning of some data, and the code is in need of some refactoring.

If you know something that isn't present in the documentation, please let me know with an issue!

References used

The TEdit World Parser, the most accurate source currently available.
The tModLoader wiki, containing lists of all possible IDs.
The Terrafirma world documentation, accurate for old worlds (version <69)
The 1.3.x.x world documentation, a bit incomplete, but an useful source nevertheless.

PyPy

lihzahrd is compatible with PyPy, a faster implementation of Python!

If you think that parsing a world takes too much time, you can use PyPy to reduce the required time by a factor of ~3!

Benchmarks

Time to parse the same large world:

CPython took 11.45 s.
Pypy took 3.57 s!
