解决snacks.nvim菜单切换问题

问题核心

你当前的配置存在两个关键问题：

初始current变量标识错误，主仪表盘并非main，且配置结构不符合snacks.nvim的要求
switch_menu仅修改变量，未触发仪表盘重新渲染，导致菜单无法切换

修正方案

1. 调整配置结构

将主菜单与二级菜单统一放在dashboard配置下作为独立子项，确保snacks.nvim能正确识别不同菜单的配置。

2. 修复切换逻辑

修改switch_menu函数，在更新当前菜单标识后，主动调用仪表盘打开方法完成页面切换。

3. 优化pick函数

确保pick函数能根据当前标识加载对应的菜单配置。

完整修正代码

local current_dashboard = "main"

function _G.switch_menu(target)
  current_dashboard = target
  -- 重新打开仪表盘以切换菜单
  require("snacks.dashboard").open()
end

return {
  "snacks.nvim",
  opts = {
    dashboard = {
      -- 主菜单配置
      main = {
        header = "主菜单",
        ---@type snacks.dashboard.Item[]
        keys = {
          { icon = " ", key = "f", desc = "项目菜单", action = ":lua switch_menu('projects')" }
        },
      },
      -- 二级项目菜单配置
      projects = {
        header = "项目菜单",
        ---@type snacks.dashboard.Item[]
        keys = {
          { icon = " ", key = "f", desc = "新建项目", action = ":lua print('新建项目')" },
          { icon = "← ", key = "b", desc = "返回主菜单", action = ":lua switch_menu('main')" }
        },
      },
      -- 根据当前标识加载对应菜单
      pick = function(_, opts)
        return require("snacks").pick(current_dashboard, opts)
      end,
    },
  },
}
