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](http://gh.steffo.eu/lihzahrd/html/world.html).

## Documentation

The documentation is available [here](https://gh.steffo.eu/lihzahrd/html/).

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](https://github.com/Steffo99/lihzahrd/issues/new)!

## PyPy

`lihzahrd` is compatible with [PyPy](https://www.pypy.org), 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!
