c++静态代码检查
可以保证在提交代码的时候的规范
cpplint
这个只做格式的规范检查
Google风格
--counting
输出结果统计，有三个选项, 默认选项是 total：
- total :只输出错误总数
- toplevel :输出各顶层分类的错误统计，比如说 ‘build’, ‘whitespace’
- detailed :输出各子分类的错误统计，比如说 ‘build/class’, ‘whitespace/braces’
--filter
过滤器，+是包含，-是不包含
cpplint --filter=可以输出支持的所有选项
--filter=-whitespace,+whitespace/braces
--filter=whitespace,runtime/printf,+runtime/printf_format
--filter=-,+build/include_what_you_use
--linelength
一行代码的长度限制。默认值为 80 个字符，超 80 个字符后，会提示错误。对于现代的大屏幕来说，我感觉 80 个字符太小了，设置为 120 比较合理。
$ cpplint --linelength=120 bucket.cpp

git 提交前自动检查
使用git pre-commit hooks
