neosnippet#expand does nothing

[naquad]

Hi.

I'm trying to implement a command that will expand given snippet (need it for Denite menu). Currently it looks like this:

command! -nargs=1 ExpandSnippet :call neosnippet#expand(<f-args>)

I try to invoke it as :ExpandSnippet date_english and nothing happens. But typing it in manually and pressing tab works fine.

Neosnippet is current master NeoVIM is 0.3.0

P. S. I've tried to let g:neosnippet#enable_completed_snippet=1 but that didn't help.

You cannot use it from command. You need to call neosnippet#expand() as mapping-<expr>.

It is invalid usage. Closing.

I don't want to support it from Denite. It is complex.

It is different feature.

Ok do you have any ideas on how to invoke neosnippet from outside of mapping? I've tried feedkeys() and norm command, but no luck.

I've came up with this:

function! s:InvokeSnippet(snip) abort
  exec "nmap <buffer><silent><expr> \\tmp_expand neosnippet#expand('" . escape(a:snip, '\\''') . "')"
  norm \tmp_expand
  nunmap <buffer> \tmp_expand
  call cursor('.', col('.') + 1)
  startinsert
endfunction

command! -nargs=1 InvokeSnippet :call <SID>InvokeSnippet(<f-args>)

Super ugly, but works.

Even better:

function! s:InvokeSnippet(trigger) abort
  let snippets = neosnippet#helpers#get_snippets()
  if ! has_key(snippets, a:trigger)
    return
  endif

  let col = col('.')
  let pre = getline('.')[:col - 1]
  let snippet = snippets[a:trigger]

  call neosnippet#view#_insert(snippet.snip, snippet.options, pre, col + 1)
endfunction

command! -nargs=1 InvokeSnippet :call <SID>InvokeSnippet(<f-args>)
