# peace-performance-python

*Fast, To calculate star ratings and performance points for all osu! gamemodes,*
*And, quickly parse Beatmap into python objects.*

### !! Now with <https://github.com/MaxOhn/rosu-pp>

**[rosu-pp](https://github.com/MaxOhn/rosu-pp)** (Rust) binding for python based on [PyO3](https://github.com/PyO3/pyo3).

Cross-platform support.
Support synchronous and asynchronous(tokio and async_std).

*Faster than [oppai-ng](https://github.com/Francesco149/oppai-ng), see the **[benchmark](https://github.com/Pure-Peace/peace-performance-python#vs-oppai-ng)** for details.*

## Install by pip

PyPI: [https://pypi.org/project/peace-performance-python](https://pypi.org/project/peace-performance-python/)

```shell
pip install peace-performance-python
```

**Reliability**:

`check_your_osu_songs.py`

Testing on my local machine, about 70,000 maps can be calculated properly.

```shell
[ Walking (E:\osu\songs) Start... ]
[ 69146 ] .osu files founded...
[ Walking Done! ]
[ Start task ]
69146/69146; ok: 69142, err: 0; total time: 23825.90ms, avg: 0.34ms
[ All DONE ]
```

## PP Calculate

### Minimal Examples

```python
from peace_performance_python.prelude import *
from peace_performance_python.objects.utils import Mods

# Beatmap can be cached and reused!
beatmap = Beatmap('path_to_osu_file') 
result = Calculator(acc=98.8, miss=3, mods=Mods.HARDROCK | Mods.HIDDEN).calculate(beatmap) # HDHR

# Async support!
beatmap = await Beatmap.create_async_rs('path_to_osu_file')
```

### Full Examples

# import all

| **`no_leniency`**        | When calculating difficulty attributes in osu!standard, ignore stack leniency but consider sliders. Solid middleground between performance and precision, hence the default version. |
| `no_sliders_no_leniency` | When calculating difficulty attributes in osu!standard, ignore stack leniency and sliders. Best performance but slightly less precision than `no_leniency`.                          |
| `all_included`           | When calculating difficulty attributes in osu!standard, consider both stack leniency and sliders. Best precision but significantly worse performance than `no_leniency`.             |
| `async_tokio`            | Beatmap parsing will be async through [tokio](https://github.com/tokio-rs/tokio)                                                                                                     |
| `async_std`              | Beatmap parsing will be async through [async-std](https://github.com/async-rs/async-std)                                                                                             |

### Vs Oppai-ng

*peace-performance Python bindings vs [C89 oppai-ng](https://github.com/Francesco149/oppai-ng) Python bindings.*

Rust is Faster. The longer the map, the more obvious the advantages of rust.

peace-performance enables the `no_sliders_no_leniency` feature to be consistent with oppai's algorithm (faster, but loses precision).

If you need maximum precision (osu-performance) rather than performance, use `all_included` features.

**This test was run on my subsystem and had performance issues with a minimum time greater than 1ms.**
(The minimum time in windows is **86us** (padoru) and the next smallest is **192us** (hitorigoto)

### Simple Benchmarks

****Native** vs **Wrapped** beatmap object*,
**Sync** vs **Async**,
**Py async** vs **Rust async***

**Note: Rust has its own event loop (independent of python) and has performance issues due to rust's need to convert built-in futures to python coroutine. So rust async is the worst performer.**

*Read and parsing time spent on beatmap of different sizes*
(forgiving is a beatmap over 50 minutes long and takes the longest)

*There are also subtle differences in the different calling methods*
