SnipMate won't expand if there are multiple options

[boardfish]

Tried the fix in someone else's issue with UltiSnips (#89), but it's not working. When I press the enter key, a newline is created rather than expanding the snippet selected. Tested in Ruby with the def method.

I'll need the minimal vimrc, and steps to reproduce this issue.

Steps

nvim test.rb idef<TAB>

Result

Many other potential snippets appear, such as 'deft'. You can tab through them but pressing ENTER results in a newline (with the right indent for a def block, strangely).

if has('nvim')
    let s:editor_root=expand("~/.config/nvim")
else
    let s:editor_root=expand("~/.vim")
endif

(:help SnipMate) SnipMate depends on vim-addon-mw-utils and tlib.

I can't find it in your vimrc.

[boardfish]

Oh, must've overlooked including it in the trimmed .vimrc. It's definitely in my init.vim.

[roxma]

It is fixed. Use this version instead. The previous version may work, but it is deprecated.

Suppose you use the <c-u> key for expanding snippet:

imap <expr> <CR>  (pumvisible() ?  "\<c-y>\<Plug>(expand_or_nl)" : "\<CR>")
imap <expr> <Plug>(expand_or_nl) (cm#completed_is_snippet() ? "\<C-U>":"\<CR>")

[boardfish]

E117: Unknown function: cm#completed_is_snippet There's another error after that. Zero record of the function existing in the plugin after I grepped the whole directory with `grep -rnw '/home/si/.vim/bundle/nvim-completion-manager/' -e 'cm#snippet' and 'cm#complete' and 'cm#completed_is_snippet'.

[roxma]

have you pull the newest version?

[boardfish]

I did just now. It no longer errors, but deletes what was written beforehand entirely. Same test circumstances, idef<Tab><Enter> results in the word 'def' that was previously written being deleted.

I think your second ternary might be the wrong way round, I'll test it to see. Nope, looks like the problem lies in that <c-u>. How do I map it to expand a snippet?

[roxma]

Something like imap <c-u> <Plug>snipMateTrigger

You need to read the snipMate doc.
