Vim: Making Auto-Completion Smarter

Question

I use ctags, taglist, etc., to have auto completion in Vim. However, it is very limited compared to Visual Studio intellisense or Eclipse auto-completion. I am wondering whe

Answer 1

In any case, I recommend YouCompleteMe (YCM). It provides (fuzzy) matching of identifiers of your current file, as well as path-completion, integration with external completion engines,...

ad 1)
If you like the semantic completion of eclipse, use eclim to integrate vim with eclipse. (alernatively use another semantic engine for YCM)

ad 2)
These 2 play nicely together btw.,: YCM can even provide the function definition (= parameter list) of the recently completed function!

ad 3)
that's what YCM does anyways

ad 4)
not quite sure, what you mean by that one. never used ctags!

P.S.: I strongly recommend using UltiSnips and Tagbar (and if you like UndoTree) additionally, what makes vim a perfect IDE for me.
