lspkind-nvim

This tiny plugin adds vscode-like pictograms to neovim built-in lsp:

^{nvim-compe, vim-vsnip, vim-vsnip-integ, jellybeans-nvim}

Configuration

Option 1: vanilla Neovim LSP

Wherever you configure lsp put the following lua command:

require('lspkind').init({
    -- DEPRECATED (use mode instead): enables text annotations
    --
    -- default: true
    -- with_text = true,

    -- defines how annotations are shown
    -- default: symbol
    -- options: 'text', 'text_symbol', 'symbol_text', 'symbol'
    mode = 'symbol_text'

    -- default symbol map
    -- can be either 'default' (requires nerd-fonts font) or
    -- 'codicons' for codicon preset (requires vscode-codicons font)
    --
    -- default: 'default'
    preset = 'codicons',

    -- override preset symbols
    --
    -- default: {}
    symbol_map = {
      Text = "",
      Method = "",
      Function = "",
      Constructor = "",
      Field = "ﰠ",
      Variable = "",
      Class = "ﴯ",
      Interface = "",
      Module = "",
      Property = "ﰠ",
      Unit = "塞",
      Value = "",
      Enum = "",
      Keyword = "",
      Snippet = "",
      Color = "",
      File = "",
      Reference = "",
      Folder = "",
      EnumMember = "",
      Constant = "",
      Struct = "פּ",
      Event = "",
      Operator = "",
      TypeParameter = ""
    },
})

Option 2: nvim-cmp

local lspkind = require('lspkind')
cmp.setup {
  formatting = {
    format = lspkind.cmp_format({
      mode = 'symbol' -- show only symbol annotations
      maxwidth = 50, -- prevent the popup from showing more than provided characters (e.g 50 will not show more than 50 characters)

      -- The function below will be called before any actual modifications from lspkind
      -- so that you can provide more controls on popup customization. (See [#30](https://github.com/onsails/lspkind-nvim/pull/30))
      before = function (entry, vim_item)
        ...
        return vim_item
      end
    })
  }
}
