# 插件API与规范修改
|

1. 现在`plugin_system`的`__init__.py`文件中包含了所有插件API的导入,用户可以直接使用`from plugin_system import *`来导入所有API。

2. register_plugin函数现在转移到了`plugin_system.apis.plugin_register_api`模块中,用户可以通过`from src.plugin_system.apis.plugin_register_api import register_plugin`来导入。

- 顺便一提,按照1中说法,你可以这么用:

```python

from src.plugin_system import register_plugin

3. 现在强制要求的property如下,即你必须覆盖的属性有:
|
||||
- `plugin_name`: 插件名称,必须是唯一的。(与文件夹相同)
|
||||
- `enable_plugin`: 是否启用插件,默认为`True`。
|
||||
- `dependencies`: 插件依赖的其他插件列表,默认为空。**现在并不检查(也许)**

|

- `database_api.py`中的`db_query`方法调整了参数顺序以增强参数限制的同时,保证了typing正确;`db_get`方法增加了`single_result`参数,与`db_query`保持一致。
|
||||
4. 现在增加了参数类型检查,完善了对应注释
|
||||
5. 现在插件抽象出了总基类 `PluginBase`
|
||||
- 基于`Action`和`Command`的插件基类现在为`BasePlugin`,它继承自`PluginBase`,由`register_plugin`装饰器注册。
|
||||
- 基于`Event`的插件基类现在为`BaseEventPlugin`,它也继承自`PluginBase`,由`register_event_plugin`装饰器注册。
|
||||
- 基于`Action`和`Command`的插件基类现在为`BasePlugin`。
|
||||
- 基于`Event`的插件基类现在为`BaseEventPlugin`。
|
||||
- 所有的插件都继承自`PluginBase`。
|
||||
- 所有的插件都由`register_plugin`装饰器注册。
|
||||
6. 现在我们终于可以让插件有自定义的名字了!
|
||||
- 真正实现了插件的`plugin_name`**不受文件夹名称限制**的功能。(吐槽:可乐你的某个小小细节导致我搞了好久……)
|
||||
- 通过在插件类中定义`plugin_name`属性来指定插件内部标识符。
|
||||
- 由于此更改一个文件中现在可以有多个插件类,但每个插件类必须有**唯一的**`plugin_name`。
|
||||
- 在某些插件加载失败时,现在会显示包名而不是插件内部标识符。
|
||||
- 例如:`MaiMBot.plugins.example_plugin`而不是`example_plugin`。
|
||||
- 仅在插件 import 失败时会如此,正常注册过程中失败的插件不会显示包名,而是显示插件内部标识符。(这是特性,但是基本上不可能出现这个情况)
|
||||
7. 现在不支持单文件插件了,加载方式已经完全删除。

```python
|
||||
plugin_path = Path(plugin_file)
|
||||
if plugin_path.parent.name != "plugins":
|
||||
# 插件包格式:parent_dir.plugin
|
||||
module_name = f"plugins.{plugin_path.parent.name}.plugin"
|
||||
else:
|
||||
# 单文件格式:plugins.filename
|
||||
module_name = f"plugins.{plugin_path.stem}"

```
|

```python
|
||||
plugin_path = Path(plugin_file)
|
||||
module_name = ".".join(plugin_path.parent.parts)
|
||||
```
|
||||
这两个区别很大的。
