neocomplcache tips:

1. The filename completion considers ‘cdpath’.
2. neocomplcache implemented short filename completion.
   Example: When you supplement “/usr/local/bin/hoge”, you input an initial, “/u/l/b”.
3. Disable auto popup
   let g:neocomplcache_disable_auto_complete = 1
4. Popup on <Tab>
   inoremap <expr><TAB> pumvisible() ? “\<C-n>” : <SID>check_back_space() ? “\<TAB>” : “\<C-x>\<C-u>\<C-p>\<Down>”
   function! s:check_back_space()“{{{
   let col = col(‘.’) – 1
   return !col || getline(‘.’)[col – 1] =~ ‘\s’
   endfunction”}}}
5. Auto complete to common string and show available variants (if any)
   inoremap <expr><C-l> neocomplcache#complete_common_string()
6. Highlighting first candidate
   let g:neocomplcache_enable_auto_select = 1
   inoremap <expr><C-h> neocomplcache#smart_close_popup().“\<C-h>”
   inoremap <expr><BS> neocomplcache#smart_close_popup().“\<C-h>”
7. Choose candidate with <CR>
   inoremap <expr><CR> neocomplcache#smart_close_popup() . “\<CR>”
