简单使用
from arclet.alconna import Alconna, Option, Subcommand, Args
cmd = Alconna(
"/pip",
options=[
Subcommand("install", [Option("-u|--upgrade")], Args.pak_name[str]),
Option("list"),
]
)
result = cmd.parse("/pip install cesloi --upgrade") # 该方法返回一个Arpamar类的实例
print(result.get('install')) # 或者 result.install
其结果为
{'pak_name': 'cesloi', 'upgrade': Ellipsis}

特点
高效. 在 i5-10210U 处理器上, 性能大约为 41000~101000 msg/s
精简、多样的构造方法
强大的自动类型转换功能
可传入同步与异步的action函数
高度自定义的HelpFormat、Analyser
Duplication、FuzzyMatch等一众特性
类型转换示范:
from arclet.alconna import Alconna, Args
from pathlib import Path
read = Alconna(
"read", Args["data":bytes],
action=lambda data: print(type(data))
)
read.parse(["read", b'hello'])
read.parse("read test_fire.py")
read.parse(["read", Path("test_fire.py")])
'''
<class 'bytes'>
<class 'bytes'>
<class 'bytes'>
'''
模糊匹配示范:
from arclet.alconna import Alconna
alc = Alconna('!test_fuzzy', "foo:str", is_fuzzy_match=True)
alc.parse("!test_fuzy foo bar")
'''
!test_fuzy not matched. Are you mean "!test_fuzzy"?
