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

[Shigio YAMAGUCHI]

Hi,

Thank you for your testing.

I have committed the patch.

The next release of GLOBAL will include it.

Regards,

Shigio

I corrected the bug by a little different method.

When you can test, it's lucky.

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);

}

^C

$ gtags --version

 [1] extracting tags of cvt.cpp

[Wed Jul 08 13:11:29 CEST 2015] Done.

$ 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

[Wed Jul 08 13:14:09 CEST 2015] Gtags started.

$ global -x my_type1

$ global -x my_type2

my_type2            2 cvt.cpp          typedef float my_type2;
