# Alconna Graia
该项目为 [`Alconna`](https://github.com/ArcletProject/Alconna) 为 [`GraiaProject`](https://github.com/GraiaProject) 下项目的内建支持
包括解析器、Dispatcher、SayaSchema 和 附加组件
## 安装
```shell
pip install arclet-alconna-graia, arclet-alconna-ariadne
pdm add arclet-alconna-graia, arclet-alconna-ariadne
```
或
```shell
pip install arclet-alconna-graia, arclet-alconna-avilla
pdm add arclet-alconna-graia, arclet-alconna-avilla
```
## 前提
Alconna-Graia 现在依赖 `Launart` 的 `service` 功能
你需要在你使用 Alconna-Graia 组件时加入如下代码:
```python
from launart import Launart
from arclet.alconna.graia import AlconnaGraiaService
from arclet.alconna.xxx import AlconnaXXXAdapter
...
manager = Launart(...)
manager.add_service(AlconnaGraiaService(AlconnaXXXAdapter))
```
`adapater` 的使用可以直接导入:
```python
from launart import Launart
from arclet.alconna.graia import AlconnaGraiaService
import arclet.alconna.xxx
...
manager = Launart(...)
manager.add_service(AlconnaGraiaService())
```
或传入 endpoint, 其等价于直接导入:
```python
from launart import Launart
from arclet.alconna.graia import AlconnaGraiaService
...
manager = Launart(...)
manager.add_service(AlconnaGraiaService("xxx"))
```
不指定 adapter 时 Alconna-Graia 默认使用基础 adapter
## 快速使用
### 单文件
ariadne:
```python
from arclet.alconna import Args
from arclet.alconna.graia import Alconna, AlconnaDispatcher, Match, AlconnaProperty
from arclet.alconna.graia.service import AlconnaGraiaService
import arclet.alconna.ariadne
...
manager = Launart(...)
manager.add_service(AlconnaGraiaService())
app = Ariadne(...)
alc = Alconna("!jrrp", Args["sth", str, 1123])
@app.broadcast.receiver(
GroupMessage,
dispatchers=[AlconnaDispatcher(alc, send_flag='stay')]
)
async def test2(
group: Group,
result: AlconnaProperty[GroupMessage],
sth: Match[str]
):
print("sign:", result.result)
print("sender:", group)
print("match", sth.available, sth.result)
```
avilla:
```python
from arclet.alconna import Args
from arclet.alconna.graia import Alconna, AlconnaDispatcher, Match, AlconnaProperty
from arclet.alconna.graia.service import AlconnaGraiaService
import arclet.alconna.avilla
...
broadcast = create(Broadcast)
manager = Launart(...)
manager.add_service(AlconnaGraiaService())
avilla = Avilla(...)
alc = Alconna("!jrrp", Args["sth", str, 1123])
@broadcast.receiver(
MessageReceived,
dispatchers=[AlconnaDispatcher(alc, send_flag='stay')]
)
async def test2(
context: Context,
result: AlconnaProperty[MessageReceived],
sth: Match[str]
):
print("sign:", result.result)
print("sender:", context.scene)
print("match", sth.available, sth.result)
```
### 使用 Saya
in module.py:
```python
from arclet.alconna.graia import Alconna, AlconnaDispatcher, Match, AlconnaProperty, AlconnaSchema
from arclet.alconna import Args
...
channel = Channel.current()
alc = Alconna("!jrrp", Args["sth", str, 1123])
@channel.use(AlconnaSchema(AlconnaDispatcher(alc)))
@channel.use(ListenerSchema([...]))
async def test2(result: AlconnaProperty[...], sth: Match[str]):
print("sign:", result.result)
print("match", sth.available, sth.result)
```
in main.py:
```python
from arclet.alconna.graia import AlconnaBehaviour
from creart import create
...
saya = create(Saya)
create(AlconnaBehaviour)
with saya.module_context():
saya.require("module")
```
### 使用 Saya Util
in module.py:
```python
from graiax.shortcut.saya import listen
from arclet.alconna.graia import alcommand, Alconna, Match, from_command, startswith, endswith
from arclet.alconna import Args, Arpamar
...
@alcommand(Alconna("!jrrp", Args["sth", str, 1123]), private=False)
async def test1(result: Arpamar, sth: Match[str]):
print("sign:", result)
print("match", sth.available, sth.result)
@alcommand("[!|.]hello <name:str>;say <word>", send_error=True)
async def test1(result: Arpamar, name: Match[str]):
print("sign:", result)
print("match", name.available, name.result)
@listen(...)
@from_command("foo bar {baz}")
async def test2(baz: int):
print("baz", baz)
@listen(...)
@startswith("foo bar")
async def test3(event: ...):
...
@listen(...)
@endswith(int)
async def test4(event: ...):
...
```
in main.py:
```python
from creart import create
...
saya = create(Saya)
with saya.module_context():
saya.require("module")
```
## AlconnaDispatcher 参数说明
```python
class AlconnaDispatcher(BaseDispatcher, Generic[TOHandler]):
def __init__(
self,
command: Alconna | AlconnaGroup,
*,
send_flag: Literal["reply", "post", "stay"] = "stay",
skip_for_unmatch: bool = True,
message_converter: Callable[[str], MessageChain | Coroutine[Any, Any, MessageChain]] | None = None,
): ...
```
`command`: 使用的 Alconna 指令
`send_flag`: 解析期间输出信息的发送方式
- reply: 直接发送给指令发送者
- post: 以事件通过 Broadcast 广播
- stay: 存入 AlconnaProperty 传递给事件处理器
`skip_for_unmatch`: 解析失败时是否跳过, 否则错误信息按 send_flag 处理
`message_converter`: send_flag 为 reply 时 输出信息的预处理器
## 附加组件
- `Match`: 查询某个参数是否匹配,如`foo: Match[int]`。使用时以 `Match.available` 判断是否匹配成功,以
`Match.result` 获取匹配结果
- `Query`: 查询某个参数路径是否存在,如`sth: Query[int] = Query("foo.bar")`;可以指定默认值如
`Query("foo.bar", 1234)`。使用时以 `Query.available` 判断是否匹配成功,以 `Query.result` 获取匹配结果
- `Header`: 表示命令头部为特殊形式时的头部匹配
- `assign`: 依托路径是否匹配成功为命令分发处理器。
```python
from arclet.alconna.graia import assign, alcommand
from arclet.alconna import Alconna, Arpamar
...
alc = Alconna(...)
@alcommand(alc, private=False)
@assign("foo")
async def foo(result: Arpamar):
...
@alcommand(alc, private=False)
@assign("bar.baz", 1)
async def bar_baz_1(result: Arpamar):
...
```
## 便捷方法
```python
from arclet.alconna.graia import Match, Alc
...
@app.broadcast.receiver(
..., dispatchers=[Alc.from_format("foo bar {baz:int}")]
)
async def test2(baz: Match[int]):
print("match", baz.available, baz.result)
```
or
```python
from arclet.alconna.graia import Match, AlconnaSchema
...
channel = Channel.current()
@channel.use(AlconnaSchema.from_("foo <arg:str>", "bar"))
@channel.use(ListenerSchema([...]))
async def test2(sth: Match[str]):
print("match", sth.available, sth.result)
```
