- Origin: https://zxq.co/ripple/lets
- Mirror: https://github.com/osuripple/lets

## Latest Essential Tatoe Server
This server handles every non real time client feature, so:
- Ingame scoreboards
- Score submission
- Screenshots
- Replays
- osu!direct, thanks to [cheesegull](https://github.com/osuripple/cheesegull)
- Tillerino-like API (partially broken)
- osu!standard and taiko pp calculation with [oppai-ng](https://github.com/francesco149/oppai-ng), made by Franc[e]sco
- osu!mania pp calculation with a slightly edited version of [osu-tools](https://github.com/ppy/osu-tools), made by the osu! team
- catch the beat pp calculation with [catch-the-pp](https://github.com/osuripple/catch-the-pp), made by Sunpy and cythonized by Nyo

## Requirements
- Python 3.6
- Cython
- C compiler

## How to set up LETS
First of all, initialize and update the submodules
```
$ git submodule init && git submodule update
```
afterwards, install the required dependencies with pip
```
$ pip install -r requirements.txt
```
compile all `*.pyx` files to `*.so` or `*.dll` files using `setup.py` (distutils file).
This compiles `catch-the-pp` as well.
```
$ python3 setup.py build_ext --inplace
```
then, run LETS once to create the default config file and edit it
```
$ python3 lets.py
$ nano config.ini
```
finally, compile oppai-ng (inside pp/oppai-ng) and osu-tools (inside pp/maniapp-osu-tools).

## tomejerry.py
`tomejerry.py` is a tool that allows you to calculate pp for specific scores. It's extremely useful to do mass PP recalculations if you mess something up. It uses lets' config and packages, so make sure lets is installed and configured correctly before using it.
```
usage: tomejerry.py [-h]
                    [-r | -z | -i ID | -m MODS | -g GAMEMODE | -u USERID | -b BEATMAPID | -fhd]
                    [-w WORKERS] [-cs CHUNKSIZE] [-v]
