Re: global c++ parser misses C++11 type alias (using)

Dear Shigio,

Thanks for the patch! It works very well, and fixes the bug that was in my submitted patch. I’ll be using your patch from now on.

Cheers,

Hi,

Thank you for the patch.

I corrected the bug by a little different method.

When you can test, it's lucky.

Regards,

OS: Linux Ubuntu 14.04LTS & Mac OS X 10.10.2

GLOBAL: v6.5, built from source via configure && make && make install

COMMAND : gtags -v

EXPECT: detect C++11 type alias (using A = B;)

RESULT: C++11 type alias is not tagged

Here is the reproducer:

—————————————

$ cat > cvt.cpp

using my_type1 = double;

typedef float my_type2;

my_type2 cvt(my_type1 x)

{

   return static_cast<my_type2>(x);

}

$ global -x my_type1

$ global -x my_type2

my_type2            2 cvt.cpp          typedef float my_type2;

Attached is a simple patch [by no means complete] that seems to fix the problem:

$ patch -p1 < global-6.5-using.patch 

patching file libparser/Cpp.c

$ make && make install

$ rm -rf G*

$ gtags -v

$ global -x my_type1

$ global -x my_type2
