The Neosnippet plug-In adds snippet support to Vim. Snippets are small templates for commonly used code that you can fill in on the fly. To use snippets can increase your productivity in Vim a lot. The functionality of this plug-in is quite similar to plug-ins like snipMate.vim or snippetsEmu.vim. But since you can choose snippets with the neocomplcache / neocomplete interface, you might have less trouble using them, because you do not have to remember each snippet name.

To install neosnippet and other Vim plug-ins it is recommended to use one of the popular package managers for Vim, rather than installing by drag and drop all required files into your .vim folder.

Notes:

• Vim 7.4 or above is needed.

• Default snippets files are available in: neosnippet-snippets

• Installing default snippets is optional. If choose not to install them, you must deactivate them with g:neosnippet#disable_runtime_snippets.

• neocomplcache/neocomplete is not required to use neosnippet, but it's highly recommended.

• Extra snippets files can be found in: vim-snippets.

1. Install the neocomplcache/ neocomplete and neosnippet-snippets first.
2. Put files in your Vim directory (usually ~/.vim/ or %PROGRAMFILES%/Vim/vimfiles on Windows).

1. Setup the vundle package manager

2. Set the bundles for neocomplcache or neocomplete And neosnippet And neosnippet-snippets

   Plugin 'Shougo/neocomplcache'
   or
   Plugin 'Shougo/neocomplete'
   
   Plugin 'Shougo/neosnippet'
   Plugin 'Shougo/neosnippet-snippets'

3. Open up Vim and start installation with :PluginInstall

1. Setup the neobundle package manager

2. Set the bundles for neocomplcache or neocomplete And neosnippet And neosnippet-snippets

   NeoBundle 'Shougo/neocomplcache'
   or
   NeoBundle 'Shougo/neocomplete'
   
   NeoBundle 'Shougo/neosnippet'
   NeoBundle 'Shougo/neosnippet-snippets'

3. Open up Vim and start installation with :NeoBundleInstall

1. Setup the vim-addon-manager package manager.

2. Add neosnippet to the list of addons in your vimrc:

   call vam#ActivateAddons(['neosnippet', 'neosnippet-snippets'])

   . Installation will start automatically when you open vim next time.

This is an example ~/.vimrc configuration for Neosnippet. It is assumed you already have Neocomplcache configured. With the settings of the example, you can use the following keys:

• C-k to select-and-expand a snippet from the Neocomplcache popup (Use C-n and C-p to select it). C-k can also be used to jump to the next field in the snippet.
• Tab to select the next field to fill in the snippet.

" Plugin key-mappings.
" Note: It must be "imap" and "smap".  It uses <Plug> mappings.
imap <C-k>     <Plug>(neosnippet_expand_or_jump)
smap <C-k>     <Plug>(neosnippet_expand_or_jump)
xmap <C-k>     <Plug>(neosnippet_expand_target)

" SuperTab like snippets behavior.
" Note: It must be "imap" and "smap".  It uses <Plug> mappings.
imap <C-k>     <Plug>(neosnippet_expand_or_jump)
"imap <expr><TAB>
" \ pumvisible() ? "\<C-n>" :
" \ neosnippet#expandable_or_jumpable() ?
" \    "\<Plug>(neosnippet_expand_or_jump)" : "\<TAB>"
smap <expr><TAB> neosnippet#expandable_or_jumpable() ?
\ "\<Plug>(neosnippet_expand_or_jump)" : "\<TAB>"

" For conceal markers.
if has('conceal')
  set conceallevel=2 concealcursor=niv
endif

If you want to use a different collection of snippets than the built-in ones, then you can set a path to the snippets with the g:neosnippet#snippets_directory variable (e.g Honza's Snippets)

But if you enable g:neosnippet#enable_snipmate_compatibility, neosnippet will load snipMate snippets from runtime path automatically.

" Enable snipMate compatibility feature.
let g:neosnippet#enable_snipmate_compatibility = 1

" Tell Neosnippet about the other snippets
let g:neosnippet#snippets_directory='~/.vim/bundle/vim-snippets/snippets'
