When cmp is active, jump forward doesnt go forward.

[otavioschwanck]

My config:

        ["<Tab>"] = cmp.mapping(
          function(fallback)
            cmp_ultisnips_mappings.compose { "jump_forwards" }(fallback)
          end,
          { "i", "s", --[[ "c" (to enable the mapping in command mode) ]] }
        ),
        ["<S-Tab>"] = cmp.mapping(
          function(fallback)
            cmp_ultisnips_mappings.compose { "jump_backwards" }(fallback)
          end,
          { "i", "s", --[[ "c" (to enable the mapping in command mode) ]] }
        ),

I dont want tab to move forward / backwards on autocomplete list (i use C-n and C-p for this). Tab is just for snippets.

Which key do you press to expand the snippet? Right now, jumping to the next placeholder only works if the snippet was already expanded (the item was selected from cmp's menu). The default in cmp is <cr> by the way.

For example, I have this mapping:

    ["<C-f>"] = cmp.mapping(
      cmp.mapping.confirm {
        behavior = cmp.ConfirmBehavior.Replace,
        select = true,
      },
      { "i", "s" }
    ),

I am having a similar issue, potentially the same. I am using return to expand snippets, and also set tab and s-tab to jump forward and backward like mentioned above. After expended a snippet, the cursor jumps to the first placeholder in select mode waiting for user input.

• If I replace the placeholder text by typing a few characters, I am then in insert mode. Tab will jump to the next placeholder with no problem
• However, if I press tab to jump the second placeholder without typing anything (essentially still in select mode), it will not jump. Instead, the tab kicks me out of select mode and goes into normal mode.

@Guzzii could you share your nvim-cmp config? It might be a configuration issue because I can't reproduce it (<Tab> moves me to the next placeholder even in select mode).

[Guzzii]

Sure, below is my config

vim.cmd('set completeopt=menu,menuone,noselect')

local cmp = require('cmp')
local lspkind = require('lspkind')
local cmp_ultisnips_mappings = require('cmp_nvim_ultisnips.mappings')

cmp.setup({
  snippet = {
    -- REQUIRED - you must specify a snippet engine
    expand = function(args)
      vim.fn['UltiSnips#Anon'](args.body) -- For `ultisnips` users.
    end,
  },
  sources = cmp.config.sources({
    { name = 'nvim_lsp' }, { name = 'ultisnips' },
    { name = 'buffer' }, { name = 'nvim_lua' },
    { name = 'tmux' }, { name = 'emoji' }
  }),
  mapping = {
    ['<C-b>'] = cmp.mapping(cmp.mapping.scroll_docs(-4), { 'i', 'c' }),
    ['<C-f>'] = cmp.mapping(cmp.mapping.scroll_docs(4), { 'i', 'c' }),
    ['<C-Space>'] = cmp.mapping(cmp.mapping.complete(), { 'i', 'c' }),
    ['<C-y>'] = cmp.config.disable, -- Specify `cmp.config.disable` if you want to remove the default `<C-y>` mapping.
    ['<C-e>'] = cmp.mapping({ i = cmp.mapping.abort(), c = cmp.mapping.close(), }),
    ['<CR>'] = cmp.mapping.confirm({ select = false }), -- Accept currently selected item. Set `select` to `false` to only confirm explicitly selected items.
    ['<Tab>'] = cmp.mapping(
      function(fallback)
        cmp_ultisnips_mappings.compose {'select_next_item', 'jump_forwards'}(fallback)
      end, {'i', 's'}
    ),
    ['<S-Tab>'] = cmp.mapping(
      function(fallback)
        cmp_ultisnips_mappings.compose {'select_prev_item', 'jump_backwards'}(fallback)
      end, {'i', 's'}
    ),
    ['<Down>'] = cmp.mapping(cmp.mapping.select_next_item(), {'i', 's', 'c'}),
    ['<Up>'] = cmp.mapping(cmp.mapping.select_prev_item(), {'i', 's', 'c'}),
  },
  formatting = {
    format = lspkind.cmp_format({
      with_text = true,
      menu = {
        buffer = '[Buffer]',
        nvim_lsp = '[LSP]',
        nvim_lua = '[Lua]',
        ultisnips = '[UltraSnip]',
        tmux = '[Tmux]',
        emoji = '[Emoji]',
      }
    }),
  },
})

-- Use buffer source for `/` (if you enabled `native_menu`, this won't work anymore).
cmp.setup.cmdline('/', { sources = {{ name = 'buffer' }}})

-- Use cmdline & path source for ':' (if you enabled `native_menu`, this won't work anymore).
cmp.setup.cmdline(':', {
  sources = cmp.config.sources({{ name = 'path' }}, {{ name = 'cmdline' }})
})

Sorry, I still can't reproduce it with your config. For some reason, setting <cr> as the key to confirm the selected item does not even work for me (it does not expand the snippet). Can you check that smap <Plug> contains the three mappings cmpu-expand, cmpu-jump-forwards and cmpu-jump-backwards?

[Guzzii]

Just to confirm, with the latest update, it is working as expected and no longer an issue.

Perfect, thanks for letting me know!
