 Vim does not provide automatic completion by itself, but there exist at least

+|youcompleteme| is probably the most popular code-completion engine for Vim.  The
+github repository is here: https://github.com/Valloric/YouCompleteMe.
+It is described as:

+> YouCompleteMe is a fast, as-you-type, fuzzy-search code completion engine
+> for Vim. It has several completion engines: an identifier-based engine that
+> works with every programming language, a semantic, Clang [3]-based engine
+> that provides native semantic code completion for the C-family languages,
+> a Jedi [4]-based completion engine for Python, an OmniSharp [5]-based
+> completion engine for C# and an omnifunc-based completer that uses data from
+> Vim's omnicomplete system to provide semantic completions for many other
+> languages (Ruby, PHP etc.).
 
 To enable automatic completion with YouCompleteMe, it has to be explicitely
-enabled for the tex filetype. For tex files, it is also a good idea to disable
