Disable nvim-cmp when vsnip snippet is available

[ilhamfu]

i had a problem when using nvim-cmp with vsnip, whenever I press tab when inside vsnip snippet it select the next item from nvim-cmp list instead moving to the next marker from vsnip, the vsnip keybinding is loaded before the nvim-cmp setup

imap <expr> <Tab>   vsnip#jumpable(1)   ? '<Plug>(vsnip-jump-next)'      : '<Tab>'
smap <expr> <Tab>   vsnip#jumpable(1)   ? '<Plug>(vsnip-jump-next)'      : '<Tab>'
imap <expr> <S-Tab> vsnip#jumpable(-1)  ? '<Plug>(vsnip-jump-prev)'      : '<S-Tab>'
smap <expr> <S-Tab> vsnip#jumpable(-1)  ? '<Plug>(vsnip-jump-prev)'      : '<S-Tab>'

cmp.setup{
    snippet = {
        expand = function(args)
            vim.fn["vsnip#anonymous"](args.body)
        end
    },
    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(),
        },
        ['<Tab>'] = function (fallback)
            if cmp.visible() then
                cmp.select_next_item()
            else
                fallback()
            end
        end,
        -- Accept currently selected item. If none selected, `select` first item.
        -- Set `select` to `false` to only confirm explicitly selected items.
        ['<CR>'] = cmp.mapping.confirm({ select = true }),
    },
    sources = cmp.config.sources{
        {name='nvim_lua'},
        {name='nvim_lsp',max_item_count=10},
        {name='vsnip',max_item_count=10},
        {name='buffer',keyword_length=5}
    },
    formatting = {
        format = lspkind.cmp_format{
            with_text = true,
            menu = {
                buffer='[BUF]',
                nvim_lsp='[LSP]'
            }
        }
    },
    experimantal = {
        native_menu = false,
        ghost_text = true
    }
}

You should remove the vsnip mappings and move that logic into the nvim-cmp configuration, like this:

local function replace_keys(str)
  return vim.api.nvim_replace_termcodes(str, true, true, true)
end

cmp.setup({
  -- ...

  mapping = {
    ['<Tab>'] = cmp.mapping(function(fallback)
      if vim.call('vsnip#available', 1) ~= 0 then
        vim.fn.feedkeys(replace_keys('<Plug>(vsnip-jump-next)'), '')
      elseif cmp.visible() then
        cmp.select_next_item()
      else
        fallback()
      end
    end, { 'i', 's' }),

    ['<S-Tab>'] = cmp.mapping(function(fallback)
      if vim.call('vsnip#available', -1) ~= 0 then
        vim.fn.feedkeys(replace_keys('<Plug>(vsnip-jump-prev)'), '')
      elseif cmp.visible() then
        cmp.select_prev_item()
      else
        fallback()
      end
    end, { 'i', 's' }),

    -- ...
  },

  -- ...
})

Thanks for the answer I implement it and now I realize that sometimes I need to use the completion while using the snippet, so instead I map <ESC> to close the completion. still thank you for the answer
