# EAI Agent Playground

挑选角色卡，输入需求，查看 agent 回复。会话状态在 notebook 生命周期内保留。

## Setup

```elixir
Mix.install([
  {:eai, path: ".."},
  {:kino, "~> 0.12"}
])
```

## 选择角色卡

```elixir
input = Kino.Input.select(
  "角色卡",
  Enum.map(Eai.Card.names(), &{Atom.to_string(&1), &1})
)

session_input = Kino.Input.text("会话名", default: "playground_#{System.unique_integer([:positive])}")

form = Kino.Control.form([input, session_input], submit: "运行")

frame = Kino.Frame.new()

form
|> Kino.Control.stream()
|> Kino.Control.tag_frame(frame)
|> Kino.listen(fn event ->
  %{data: %{card: card, session: session}} = event
  content = IO.gets("需求> ") |> to_string() |> String.trim()

  frame
  |> Kino.Frame.render(
    Kino.Markdown.new("**运行中**，角色卡=`#{card}`，会话=`#{session}`")
  )

  result =
    Eai.Chat.talk(
      content: content,
      chara_card: card,
      chat_session: session,
      mod: :function,
      timeout: 120_000
    )

  rendered =
    case result do
      {:ok, reply} ->
        Kino.Markdown.new("**回复**\n\n```\n#{reply}\n```")

      {:error, reason} ->
        Kino.Markdown.new("**失败**：`#{inspect(reason)}`")
    end

  Kino.Frame.render(frame, rendered)
end)

Kino.Layout.column([form, frame])
```

## 查看当前会话历史

```elixir
# 把下面的 session_id 改成上面 form 里你填的会话名
session_id = "playground_default"

Eai.Chat.get_history(session_id)
|> Enum.map(fn msg ->
  %{
    role: msg.role,
    content: String.slice(to_string(msg.content), 0, 200)
  }
end)
|> Kino.DataTable.new()
```
