Having a weird duplicate expansion. Tab keys aren't working for jumps.

--Approximate config
-- plugins-snippets.lua

local cmp = require("cmp")
cmp.setup({

["<CR>"] = cmp.mapping.confirm({ select = true }),
["<C-S-j>"] = cmp.mapping(function(fallback)
	if vim.fn["vsnip#jumpable"](1) == 1 then
		 feedkey("<Plug>(vsnip-jump-next")
	else
		fallback()
	end
end, {  "s" }),
["<Tab>"] = cmp.mapping(function(fallback)
 --  elseif vim.fn["vsnip#available"](1) == 1 then
	if vim.fn["vsnip#jumpable"](1) == 1 then
		 feedkey("<Plug>(vsnip-jump-next", "")
	elseif cmp.visible() then
		cmp.select_next_item()
	elseif has_words_before() then
		cmp.complete()
	else
	  --The fallback function sends a already mapped key. In this case, it's probably `<Tab>`.
		fallback()
	 end
end, { "i", "s" }),

["<S-Tab>"] = cmp.mapping(function()
  if vim.fn["vsnip#jumpable"](-1) == 1 then
	  feedkey("<Plug>(vsnip-jump-prev)", "")
  elseif cmp.visible() then
	  cmp.select_prev_item()
  end
end, { "i", "s" }),

• NVIM v0.9.0-dev-a0a1125

• cmp-vsnip: 989a8a7
• Packer.nvim

After the commit 18ff44c the behavior when I press tab changes from expanding the string to the full snippet prefix to now expanding to the first line in the snippet's body.

I am trying to understand the intention behind that change, so that I can modify my workflow or perhaps change my snippet to work with this change.

The way I am using is to first expand to the full "name" of the snippet first and have another mapping to expand it to the full body. Perhaps the change is trying to do both at once but I can't find a way to set my snippet in such a way that it works.

It works well with nvim-compe, vim-vsnip, and vim-vsnip-integ.

My vsnip snippets:

{
  "Date": {
    "prefix": ["date"],
    "body": ["${CURRENT_YEAR}-${CURRENT_MONTH}-${CURRENT_DATE}"],
    "description": "Date"
  },
  "Datetime": {
    "prefix": ["datetime"],
    "body": ["${CURRENT_YEAR}-${CURRENT_MONTH}-${CURRENT_DATE} ${CURRENT_HOUR}:${CURRENT_MINUTE}:${CURRENT_SECOND}"],
    "description": "Datetime"
  }
}

Hi,

Having updated my config today, I've seen that I get no snippets shown in nvim-cmp. I saw that commit 18ff44c seems to have broken my config. However, replacing the line in:

by the same line in the previous commit:

seems to have solved the issue. Do you have any idea why that should be and if a fallback to the old line is necessary?

Thanks

Some snippets cause the menu to immediately close, when selected with prev/next in the menu. They also insert a messed up version of the snippet.

Here is an example snippet:

{
  "msg": {
    "prefix": ["msg"],
    "body": [
      "[$1] $2"
    ]
  }
}

If I type ms the menu opens:

If I now just select the first item (i.e. <c-j> without confirming!), the menu closes immediately and inserts the first part of the template:

This happens since commit 18ff44c (Improve Symbol handling).

It does not happen for all snippets. I could not find out what exactly makes some snippets cause this problems, while others still work fine.

My nvim-cmp config:

  cmp.setup({
    snippet = {
      expand = function(args)
        vim.fn['vsnip#anonymous'](args.body)
      end,
    },
    mapping = {
      ['<C-j>'] = cmp.mapping(cmp.mapping.select_next_item(), {'i', 'c'}),
      ['<C-k>'] = cmp.mapping(cmp.mapping.select_prev_item(), {'i', 'c'}),
      ['<CR>'] = function(fallback)
        if cmp.visible() and
          cmp.get_selected_entry() and
          not (cmp.get_selected_entry().source.name == 'nvim_lsp_signature_help') then
          cmp.confirm({
            select = false,
          })
        else
          fallback()
        end
      end
    },
    sources = cmp.config.sources({
      { name = 'vsnip' },
    }),
  })

When I try to select the snippet hint displayed in the completion menu, I get this error:

	E5108: Error executing lua .../.vim/plugged/nvim-cmp/lua/cmp/config/default.lua:24: snippet engine is not configured.
