Can't expand on enter

[casprwang]

I hit for<tab><cr>, with the configuration from readme.

Don't use inoremap for <CR> mapping

I can reproduce using inoremap <expr> <CR> ncm2_snipmate#expand_or("\<CR>")

You should use imap.

Humm, I didn't use inoremap, you can check my vimrc here, am I missing something?

[roxma]

I have just pushed an update. The behavior should be more clear with inoremap.

" Press enter key to trigger snippet expansion
" The parameters are the some as `:help feedkeys()`
inoremap <silent> <expr> <CR> ncm2_snipmate#expand_or("\<CR>", 'n')

" c-j c-k for moving in snippet
let g:snips_no_mappings = 1
vmap <c-j> <Plug>snipMateNextOrTrigger
vmap <c-k> <Plug>snipMateBack
imap <expr> <c-k> pumvisible() ? "\<c-y>\<Plug>snipMateBack" : "\<Plug>snipMateBack"
imap <expr> <c-j> pumvisible() ? "\<c-y>\<Plug>snipMateNextOrTrigger" : "\<Plug>snipMateNextOrTrigger"

Hi Rox,

Appreciate you quick response. I updated the plugin and vimrc, but the behavior of <cr> changed to add a new line without expanding snippet.

For reproduction

" autosompletion
Plug 'roxma/nvim-yarp'
Plug 'ncm2/ncm2' "{{{
" supress the annoying 'match x of y', 'The only match' and 'Pattern not
" found' messages
set shortmess+=c

" CTRL-C doesn't trigger the InsertLeave autocmd . map to <ESC> instead.
inoremap <c-c> <ESC>

" When the <Enter> key is pressed while the popup menu is visible, it only
" hides the menu. Use this mapping to close the menu and also start a new
" line.
inoremap <expr> <CR> (pumvisible() ? "\<c-y>\<cr>" : "\<CR>")

" Use <TAB> to select the popup menu:
inoremap <expr> <Tab> pumvisible() ? "\<C-n>" : "\<Tab>"
inoremap <expr> <S-Tab> pumvisible() ? "\<C-p>" : "\<S-Tab>"

" wrap existing omnifunc
" Note that omnifunc does not run in background and may probably block the
" editor. If you don't want to be blocked by omnifunc too often, you could add
" 180ms delay before the omni wrapper:
"  'on_complete': ['ncm2#on_complete#delay', 180,
"               \ 'ncm2#on_complete#omni', 'csscomplete#CompleteCSS'],

        \ 'complete_pattern': ':\s*',
        \ 'on_complete': ['ncm2#on_complete#omni', 'csscomplete#CompleteCSS'],
        \ })

That's the expected behavior for for completion. There's no snippet associated with this completion.

If the completion is expandable, you will see a [+] sign in the completion menu field.

Ahhhh, Got it. I was thinking too much. Thanks!!!
