NeoVim cannot start lsp because clangd is not found

Thanks a lot! I was looking for a way to do exactly this.

I just split the code for better reusability and readability:

-- Get system information
local system_name = vim.loop.os_uname().sysname

if system_name == 'Linux' then
  local file = io.open('/etc/os-release', 'r')
  if file then
    local content = file:read '*all'
    file:close()
    if string.find(content, 'ID=nixos') then
      vim.g.system_id = 'nixos'
    end
  end
end

I also extracted the function that sets up the servers to re-use it for NixOS.

require('mason').setup()

local setup_servers = function(server_name)
  local server = servers[server_name] or {}
  server.capabilities = vim.tbl_deep_extend('force', {}, capabilities, server.capabilities or {})
  lspconfig[server_name].setup(server)
end

local ensure_installed = vim.tbl_keys(servers or {})
local extra_tools = {
  'stylua', -- Used to format Lua code
}

if vim.g.system_id == 'nixos' then
  for _, server_name in pairs(ensure_installed) do
    setup_servers(server_name)
  end
else
  vim.list_extend(ensure_installed, extra_tools)
  require('mason-tool-installer').setup { ensure_installed = ensure_installed }
  require('mason-lspconfig').setup { handlers = { setup_servers } }
end
