Neovim + nvim-cmp で snipmate 形式のスニペットを使いたい場合は以下のプラグインを使用する。

  {
    'hrsh7th/nvim-cmp',
    requires = {
      'dcampos/nvim-snippy',
      'dcampos/cmp-snippy',
      'hrsh7th/cmp-nvim-lsp',
      'hrsh7th/cmp-buffer',
      'hrsh7th/cmp-path',
      'hrsh7th/cmp-cmdline'
    },
    config = function()
      require('plugins.nvim-cmp')
    end
  },

設定

~/.config/nvim/lua/plugins/nvim-cmp.lua
vim.g.vsnip_snippet_dir = os.getenv('HOME')..'/.config/nvim/snippets'

local has_words_before = function()
  unpack = unpack or table.unpack
  local line, col = unpack(vim.api.nvim_win_get_cursor(0))
  return col ~= 0 and vim.api.nvim_buf_get_lines(0, line - 1, line, true)[1]:sub(col, col):match("%s") == nil
end

local snippy = require("snippy")
local cmp = require("cmp")

cmp.setup({
  snippet = {
    expand = function(args)
      require("snippy").expand_snippet(args.body)
    end,
  },
  sources = cmp.config.sources({
    { name = "nvim_lsp" },
    { name = "snippy" },
    { name = "buffer" },
    { name = "path" },
    { name = "cmdline" },
  }),

  mapping = {
    ["<CR>"] = cmp.mapping.confirm({ select = true }),
    ["<Tab>"] = cmp.mapping(function(fallback)
      if cmp.visible() then
        cmp.select_next_item()
      elseif snippy.can_expand_or_advance() then
        snippy.expand_or_advance()
      elseif has_words_before() then
        cmp.complete()
      else
        fallback()
      end
    end, { "i", "s" }),

    ["<S-Tab>"] = cmp.mapping(function(fallback)
      if cmp.visible() then

copilot.lua が動作しなかったが、~/.config/github-copilot を削除して、再認証したら動作するようになった。
