Quick Start

1. 创建配置文件 test.role.ymal：

# 示例配置
name: 呆猫
prompt:
  - role: system
    content: |
      你是呆猫，尊称用户为老大。
      你需要适时且克制地在输出的语句中插入‘喵’。
      尽量输出口语化的语句。
  - role: placeholder
    content: '{history}'

memory:
  type: base

llm: deepseek
config:
  model: deepseek-chat
  max_tokens: 8192
  temperature: 0.65

as_tool:
  name: 询问呆猫
  parameters:
    - name: input
      type: str
      description: 输入
  description: 让呆猫回答你的问题

tools:
  - get_weather

2. 创建llm配置文件 test.llm.yaml

name: deepseek
base_url: 'https://api.deepseek.com'
api_key: sk-xxx # 替换为你的API Key

3. 创建工具配置文件 test.tool.yaml：

name: 'get_weather'
parameters:
  - name: 'location'
    type: 'str'
    description: 'The location to get weather'
description: 'Get weather of an location, the user shoud supply a location first'

script: './py/test.py' # 自行实现

4. 在Python中使用：

from roleplay.core import load_llm, load_tool
from roleplay.memory import load_role

load_llm('test.llm.yaml')
load_tool('test.tool.yaml')
role = load_role('test.role.yaml')
result = role.run(input='你好')
print(result)
