C++ ctags不是索引类成员函数

我正在使用ctags索引我的源代码。 为了简单起见，我组装了一些示例代码，如下所示

namespace test_space
{
template<typename TYPE>
class A
{
public:
    void test_func(TYPE a);
    void test_func_2(TYPE a);
    void test_func_3(TYPE a);
}
class B
{
public:
    void test_func_b();
}

void easy_func()
{
}

}

---

在默认情况下，繁荣的CTAG似乎只在看到定义而不是声明时添加标记。将班级

A

更改为

template<typename TYPE>
class A
{
public:
    void test_func(TYPE a)
    {
    }
    void test_func_2(TYPE a);
    void test_func_3(TYPE a);
};

但其他功能没有显示出来。我自己不使用CTAG，但您通常希望能够找到定义，而不是声明，这是有道理的

如果您让ctags索引原型，您可以得到您想要的：

ctags --c-kinds=+p a.h

例如，这将导致

!_TAG_FILE_FORMAT   2   /extended format; --format=1 will not append ;" to lines/
!_TAG_FILE_SORTED   1   /0=unsorted, 1=sorted, 2=foldcase/

test_func   a.h /^  void test_func(TYPE a);$/;" p   class:test_space::A

test_func_3 a.h /^  void test_func_3(TYPE a);$/;"   p   class:test_space::A
test_func_b a.h /^  void test_func_b();$/;" p   class:test_space::B
test_space  a.h /^namespace test_space$/;"  n

您可以获得更多有关标记内容的详细信息，如下所示：

$ ctags --list-kinds=c
c  classes
d  macro definitions
e  enumerators (values inside an enumeration)
f  function definitions
g  enumeration names
l  local variables [off]
m  class, struct, and union members
n  namespaces
p  function prototypes [off]
s  structure names
t  typedefs
u  union names
v  variable definitions
x  external and forward variable declarations [off]

您可以看到，默认情况下，函数原型没有标记
