How to have Vim recognize the object type when accessing an STL container, for autocompletion

Question

I have the omnicppcomplete plugin with exuberant ctags, I generate tags for projects with the following command:

ctags -R --c++-kinds=+p --fields=+iaS --extra=+q .

What I am trying to achieve is to have Vim recognize the type of an object when I access it through an STL container, to provide me with an appropriate list of autocomplete suggestions.

For example suppose the IntWrapper object has a getTheInt() method and I have a vector of IntWrappers:

std::vector<IntWrapper> wrappers;

If I have the following code:

for (size_t i = 0; i < wrappers.size(); i++) {
    wrappers[i].<VIM Cursor is here>
}

I'd like VIM to understand that wrapper[i] is of type IntWrapper and to give me the getTheInt() method as the first autocompletion choice, along with documentation, as if I operated on an IntWrappers object directly.

To make clear what I would expect, the first screenshot below is what happens when I ask for autocompletion on the vector, the second one is what happens when I access the object directly, and what I'd like to achieve even with stl containers.

Working

Is there any plugin (I don't care about CPU expensiveness) to do this?

Many thanks.

@PlasmaHH no, I never did! More details about it are welcome! — Vincenzo Pii, Mar 02 '12 at 09:42

Actually, I think that omnicomplete can't deal with context issue, so you can't use it for your purpose. A way to do C++/STL auto-completion is to use clang_complete (or here).

The performance seems to be quite problematic though (Have a look here : How to improve the completion speed of clang_complete? ).

A nice tutorial on the subject (configure vim + clang for C++ STL completion) could be found here : http://zwiener.org/vimautocomplete.html

Ref:

C++98 and C++11 Support in Clang : http://clang.llvm.org/cxx_status.html
Vim Clang_complete documentation : https://github.com/krisajenkins/clang_complete/blob/master/doc/clang_complete.txt

NB : Another option is to use gccsense which is a stand alone tool using GCC's code analyzers. Here is the link to the project homepage : http://cx4a.org/software/gccsense/ and on two SO questions about its use :

`clang_complete` uses the python bindings and there is a lot of work ongoing on them, for anyone planning to use them I suggest keeping close to the trunk version. — Matthieu M., Mar 02 '12 at 09:40
