• C compiler
• MySQLdb (mysqlclient)
• Tornado
• Bcrypt
• Progressbar2 (only for tomejerry.py )
• Raven
• Datadog
• oppai

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)

$ 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, configure oppai as described below.

How to set up oppai with LETS

LETS uses lolisamurai's oppai as pp calculator for std. We use a slightly modified version of oppai, you can find it here.
Go one directory above LETS (in the same directory where you have old-frontend, pep.py, lets and so on) and clone oppai inside the oppai folder, compile it with make and create the maps folder:

$ cd ..
$ git clone https://github.com/osuripple/oppai.git
$ cd oppai
$ make
$ chmod +x oppai
$ mkdir maps

Note: wifipiano (mania pp calculator) is tailor-made for LETS and doesn't require any configuration.

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.
tomejerry supports a lot of parameters, the main ones are:

• -r, to recalculate PP for every score on every game mode (only std and mania are supported at the moment)
• -z to calculate PP for scores with 0 pp
• -g x to recalculate PP for scores for x gamemode (0: std, 3: mania)
• -i x to recalculate PP for score with x id
• -n x to recalculate PP for scores submitted by user with x username
  For a full list of all the arguments supported by tomejerry, run python3 tomejerry.py --help
