C/C++ 命名约定检查器 (ncc)

ncc 是一个开发工具，可帮助程序员编写遵循某些命名约定的 C/C++ 代码。它自动执行检查 C/C++ 代码的过程，从而使人类摆脱这项无聊（但重要）的任务。这使其成为想要强制执行编码标准的项目的理想选择。

依赖关系

以下软件包是 ncc 工具的先决条件。请注意，python 'clang' 提供 libclang python 绑定。 clang 版本应该与您系统上的 libclang.so 版本匹配

铛
yaml

 pip install clang
pip install pyyaml

视窗

在 Microsoft Windows 上安装 32 位版本的 LLVM 编译器工具链。

用法

 ncc . py [ - - help ] [ - - recurse ] [ - - style STYLE_FILE ] [ - - cdbdir CDBDIR ] [ - - dump ]
       [ - - output OUTPUT ] [ - - filetype FILETYPE ] [ - - exclude EXCLUDE [ EXCLUDE ...]]
       [ - - path PATH [ PATH ...]] [ - - include INCLUDE [ INCLUDE ...]]
       [ - - definition DEFINITION [ DEFINITION ...]] [ - - clang - lib CLANG_LIB ]

有关所有选项的详细说明：

 ncc . py - - help

打印所有规则：

    ncc . py - - dump

风格定义

c/c++ 构造的样式由正则表达式定义。例如，以下规则规定结构体可以具有任何字符，类名应以“C”开头，类成员变量应以 m_ 开头，函数名应以大写字母开头

    ClassName : ' C.* '
    CppMethod : ' [A-Z].* '
    VariableName :
        ScopePrefix :
            Global : ' g_ '
            Static : ' s_ '
            ClassMember : ' m_ '
        DataTypePrefix :
            String : ' str '
            Pointer : ' p '
            Integer : ' n '
            Bool : ' b '
        Pattern : ' ^.*$ '

用法示例

检查文件 test.cpp 是否违反命名约定：

    ./ncc.py --style examples/ncc.style --path examples/test.cpp

    examples/test.cpp:16:7: " B " does not match " ^C.*$ " associated with ClassName
    examples/test.cpp:28:9: " b " does not match " ^m_.*$ " associated with ClassMemberVariable
    examples/test.cpp:31:5: " main(int, const char **) " does not match " ^[A-Z].*$ " associated with FunctionName
    Total number of errors = 3

递归查找“examples”目录下的所有文件，但排除“ .cpp”和“ .h”文件

    ./ncc.py --style examples/ncc.style --recurse --exclude * .cpp * .h --path examples

    examples/test.hpp:4:7: " Test " does not match " ^C.*$ " associated with ClassName
    examples/test.hpp:12:9: " t " does not match " ^m_.*$ " associated with ClassMemberVariable
    examples/test.hpp:19:9: " _aaa " does not match " ^[a-z].*$ " associated with StructMemberVariable
    examples/test.c:8:9: " _b " does not match " ^[a-z].*$ " associated with StructMemberVariable
    examples/test.c:9:9: " _c " does not match " ^[a-z].*$ " associated with StructMemberVariable
    examples/tmp/test.hpp:4:7: " Test " does not match " ^C.*$ " associated with ClassName
    examples/tmp/test.hpp:12:9: " t " does not match " ^m_.*$ " associated with ClassMemberVariable
    examples/tmp/test.hpp:19:9: " _aaa " does not match " ^[a-z].*$ " associated with StructMemberVariable
    Total number of errors = 8
