If you only wanna auto-completion from cache of your current buffers  supertab is easier to install than neocomplete  can work on Mac pre-installed vim out of box without the need of MacVim   You can check other alternatives at vim awesome

I ve used neocomplcache for about half a year  It is a plugin that collects a cache of words in all your buffers and then provides them for you to auto-complete with   There is an array of screenshots on the project page in the previous link  Neocomplcache also has a ton of configuration options  of which there are basic examples on the project page as well   If you need more depth  you can look at the relevant section in my vimrc - just search for the word neocomplcache

For PHP  Padawan with Deoplete are great solutions for having a robust PHP autocompletion in Neovim  I tried a lot of things and Padawan work like a charm   For Vim you can use Neocomplete instead of Deoplete   I wrote an article how to make a Vim PHP IDE if somebody is interested  Of course Padawan is part of it

I ve just found the project Eclim linked in another question  This looks quite promising  at least for Java integration

Another option is coc nvim    It s really fast and the completion is great as it uses intellisense the same autocompletion as VScode has   It also has linting capabilities  So it shows you were you might have a bug  It supports a multitude of languages   It might take a bit to set up and configure but I thing it is the best autocompletion engine for vim out there

I recently discovered a project called OniVim  which is an electron-based front-end for NeoVim that comes with very nice autocomplete for several languages out of the box  and since it s basically just a wrapper around NeoVim  you have the full power of vim at your disposal if the GUI doesn t meet your needs  It s still in early development  but it is rapidly improving and there is a really active community around it  I have been using vim for over 10 years and started giving Oni a test drive a few weeks ago  and while it does have some bugs here and there it hasn t gotten in my way  I would strongly recommend it to new vim users who are still getting their vim-fingers     OniVim  https   www onivim io

There   s also clang complete which uses the clang compiler to provide code completion for C   projects  There   s another question with troubleshooting hints for this plugin   The plugin seems to work fairly well as long as the project compiles  but is prohibitively slow for large projects  since it attempts a full compilation to generate the tags list

User · Answer

Try YouCompleteMe  It uses Clang through the libclang interface  offering semantic C C   Objective-C completion  It s much like clang complete  but substantially faster and with fuzzy-matching   In addition to the above  YCM also provides semantic completion for C   Python  Go  TypeScript etc  It also provides non-semantic  identifier-based completion for languages for which it doesn t have semantic support

User · Answer

There is also https   github com Valloric YouCompleteMe and it includes things like Jedi and also has fuzzy match  So far I found YCM to be the fastest among what I have tried   Edit  There also exists some new ones like https   github com maralla completor vim
