neovim内置lsp使用eslint格式化

关键代码

 -- 代码保存自动格式化formatting
  if client.resolved_capabilities.document_formatting then
    vim.api.nvim_command [[augroup Format]]
    vim.api.nvim_command [[autocmd! * ]]
    vim.api.nvim_command [[autocmd BufWritePre  EslintFixAll]]
    -- vim.api.nvim_command [[autocmd BufWritePre  lua vim.lsp.buf.formatting_seq_sync()]]
    vim.api.nvim_command [[augroup END]]
  end
