|
## Installation
|
|
|
|
Lihzahrd can be installed from PyPI like any other public Python package.
|
|
|
|
Using [uv](https://docs.astral.sh/uv/), that means:
|
|
|
|
```shell
|
|
uv add lihzahrd
|
|
```
|
|
|
|
## Usage
|
|
|
|
You can open a world file and get a `World` object by calling:
|
|
|
|
```python
|
|
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).
|
|
|
|
> [!Warning]
|
|
>
|
|
> Maliciously designed Terraria worlds can drain system resources, crash the interpreter, or possibly do other evil things!
|
|
>
|
|
> **Make sure you trust worlds before parsing them!**
|

## Documentation
|
|
|
|
The documentation is available [here](https://gh.steffo.eu/lihzahrd/html/).
|
|
|
|
If you know something that is missing 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), an alternative implementation on 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!
|
|
|
|
### Building docs
|
|
|
|
You can build the docs by entering the `docs_source` folder and running `make html`, then committing the whole `docs` folder.
