下拉建议的 nvim 配置

Question

我有一个接近我想要的设置的 vim 设置。我可以在输入时在文本中输入和查看建议。那是我的目标。我安装了 NerdFonts 字体和 NerTree，我可以在 NerTree 中看到图标。我在键入时看不到下拉文本中的图标，这是我的问题。

看，在右侧，有彩色字母但没有图标。

hrsh7th/nvim-cmp正在使用nvim-web-devicons 或者您需要为每个来源设置一个图标。

按照说明here。

  cmp.setup {
  formatting = {
    format = function(entry, vim_item)
      if vim.tbl_contains({ 'path' }, entry.source.name) then
        local icon, hl_group = require('nvim-web-devicons').get_icon(entry:get_completion_item().label)
        if icon then
          vim_item.kind = icon
          vim_item.kind_hl_group = hl_group
          return vim_item
        end
      end
      return lspkind.cmp_format({ with_text = false })(entry, vim_item)
    end
  }
}

示例设置

call plug#begin(s:plug_dir)
Plug 'neovim/nvim-lspconfig'
Plug 'hrsh7th/cmp-nvim-lsp'
Plug 'hrsh7th/cmp-buffer'
Plug 'hrsh7th/cmp-path'
Plug 'hrsh7th/cmp-cmdline'
Plug 'hrsh7th/nvim-cmp'
call plug#end()

set completeopt=menu,menuone,noselect

lua <<EOF

local icon = {
  Field = ' ',
  Variable = ' ',
}

 local cmp = require'cmp'
 cmp.setup({
  formatting = {
    fields = { 'kind', 'abbr', 'menu' },
    format = function(entry, vim_item)
      vim_item.kind = icon[vim_item.kind]
      return vim_item
    end,
  },
 })
EOF
