what 's the difference of close_popup() and cancel_popup()

[flyingfishercn]

inoremap <buffer> <expr><C-y> neocomplcache#close_popup() inoremap <buffer> <expr><C-e> neocomplcache#cancel_popup()

In my environment, when I tab select words in the popupwindow, press the two key makes no difference. They all complete the word.

for example, when i type "th", "this" and "that" list in the popup-window, when i select "that", type the two key is all complete "th" to "that", and popup-window disappeared.

I think you should use neocomplcache#smart_close_popup() and neocomplcache#smart_close_popup().

In my environment, when I tab select words in the popupwindow, press the two key makes no difference. They all complete the word.

neocomplcache#close_popup() insert current candidate, but neocomplcache#cancel_popup() does not insert current candidate.

I tried as you said again, but nothing different happened. They finished the same job. Fortunately, it didn't trouble my daily work.

The following is my config:

I use neocomplete.vim. And this settings are works. I don't want to change neocomplcache. Can you test it in neocomplete.vim?

  " <C-y>: paste.
  inoremap <expr><C-y>  pumvisible() ? neocomplete#close_popup() :  "\<C-r>\""
  " <C-e>: close popup.
  inoremap <expr><C-e>  pumvisible() ? neocomplete#cancel_popup() : "\<End>"

God. I thought use OmniCppComplete as neocomplete by mistake. I checked my vim plugin and found the key error.

It is said neocomplete was better than OmniCppComplete everywhere , I will try it later. Thank you,Shougo !!

[Shougo]

OK.
