## 🚀 Usage

### Edgy Integration

```lua
{
  "folke/edgy.nvim",
  ---@module 'edgy'
  ---@param opts Edgy.Config
  opts = function(_, opts)
    for _, pos in ipairs({ "top", "bottom", "left", "right" }) do
      opts[pos] = opts[pos] or {}
      table.insert(opts[pos], {
        ft = "snacks_terminal",
        size = { height = 0.4 },
        title = "%{b:snacks_terminal.id}: %{b:term_title}",
        filter = function(_buf, win)
          return vim.w[win].snacks_win
            and vim.w[win].snacks_win.position == pos
            and vim.w[win].snacks_win.relative == "editor"
            and not vim.w[win].trouble_preview
        end,
      })
    end
  end,
}

## 📦 Setup

```lua
-- lazy.nvim
{

      -- your terminal configuration comes here
      -- or leave it empty to use the default settings
      -- refer to the configuration section below
    }

---@class snacks.terminal.Config
---@field win? snacks.win.Config|{}
---@field shell? string|string[] The shell to use. Defaults to `vim.o.shell`
---@field override? fun(cmd?: string|string[], opts?: snacks.terminal.Opts) Use this to use a different terminal implementation
{
  win = { style = "terminal" },
}

        self.esc_timer = self.esc_timer or (vim.uv or vim.loop).new_timer()
        if self.esc_timer:is_active() then
          self.esc_timer:stop()
          vim.cmd("stopinsert")
