[CEDET-devel] eassis method-list and nested namespaces in C++

From: <sgoericke@va...> - 2012-08-08 08:19


Hello,

i figured out that the method-list feature of eassist doesn't work properly if
nested namespaces are used in C++.

This example works fine:

namespace foo
{
   class bar
   {
       void do();
   };
}

For the next one no methods are shown:

namespace foo
{
   namespace baz
   {
      class bar
      {
          void do();
      };
   }
}

Because i'm a "beginner" in elisp maybe somebody could point me in the direction
how to extend the eassist package to support nested namespaces? I use the ECB
package too and it's method-buffer show all members even in nested namespaces so
i think it's not a semantic problem.

Best regards
Sven

Semantic indeed does support nested namespaces just fine. Do

M-x bovinate

to see the parser output Semantic returns. In the case of nested
namespaces, you get something like

(("foo" type
  (:members
   (("baz" type
     (:members
      (("bar" type
	(:type "class")
	(reparse-symbol namespacesubparts)
	#<overlay from 54 to 107 in foo2.cpp>))
      :type "namespace")
     (reparse-symbol namespacesubparts)
     #<overlay from 24 to 114 in foo2.cpp>))
   :type "namespace")
  nil #<overlay from 1 to 118 in foo2.cpp>))

(Just ignore the 'reparse symbol' and overlays; they're not important
for this task).

You see that namespaces are parsed as types by Semantic (with keyword
":type namespace"). All types belonging to a namespace are listed as
":members", which can again be namespaces. It seems eassist just doesn't
look deep enough.
