Pre: I've been working in VIM for like a year already. Lots of great things: combinations, scripts. Whenever I'm editing something in a different editor, I feel sluggish/uncomfortable without VIM's navigation.
The problem: The thing that really bothers me most of all is source code navigation using existing tools (ctags, cscope). Often, ctags can't find the declaration of a variable, cscope as opposed to ctags finds all definitions with the same variable name. Same craziness with call tree navigation, finding forward declarations along with a single class definition etc. Compared to MS Intellisense, Visual Assist or even source code navigation in Eclipse, Exuberant Tags/cscope seems to be deprecated for at least 10 years.
I know there are tools like ViEMU, but they don't really solve the problem, since you lose lots of VIM's functionality.
The question: I was wondering if there is a tool that does the source parsing better, or there is some way to integrate source parsing engines like Intellisense into VIM ? Maybe there are commercial solutions or there are people who are ready to implement one ?
All the benefits of VIM seem to save less time than is being wasted while navigating to class definition, compared to Visual Assist, where it's done by a single Alt-G shortcut.
Search and Call tree
You could try eclim, which is a way to use some Eclipse features in Vim.
For C/C++, it provides :
:CSearchContext
):CCallHierarchy
):Validate
)It is not great, but it can help in some cases.
Code Completion
Regarding automatic code completion, I primarily use OmniCppComplete, which is using tags to provide Context aware code completion. It is not that bad.
As advised by Luc Hermitte, you can also use clang_complete which does not need ctags, but needs clang installed.
