pyttanko 1.2.1

用法

pyttanko是一个单独的文件模块，因此使用它的最简单方法 只需将其放在项目的文件夹中：

cd my/project
curl https://raw.githubusercontent.com/Francesco149/pyttanko/master/pyttanko.py > pyttanko.py

这样，克隆项目的任何人都不必安装 Pyttanko，因为它将被捆绑

如果您愿意，也可以在pip上找到它

pip install pyttanko

也可以手动安装，如下所示：

curl -L https://github.com/Francesco149/pyttanko/archive/HEAD.tar.gz -o HEAD.tar.gz
cd pyttanko-*
python setup.py install --user

退房

pydoc pyttanko

或

python -c "help('pyttanko')"

对于完整的文档

最小示例：

#!/usr/bin/env pythonimportsysimportpyttankoasosup=osu.parser()bmap=p.map(sys.stdin)stars=osu.diff_calc().calc(bmap)print("%g stars"%stars.total)pp,_,_,_,_=osu.ppv2(stars.aim,stars.speed,bmap=bmap)print("%g pp"%pp)

您可以使用它运行：

cat /path/to/file.osu | ./example.py

性能

pyttanko运行测试套件的速度比原始测试套件慢10倍以上 C实现并使用大约8倍的内存，因此如果需要 要批量处理数千个分数，您应该考虑编写 C版本的本机绑定。

测试在Linux 4.9.38、Python2.7.10和i7-4790k上执行
