Alconna 1.8.1

[RF-Tar-Railt]

破坏性改动

• 删除 ContextVal 表达式

新增

• Namespace 与 CommandMeta 新增 context_style 属性，用于指定命令插值的格式，不填入则默认不启用插值：

  from dataclasses import dataclass
  from arclet.alconna import Alconna, Args, CommandMeta
  
  alc = Alconna("test", Args["foo", str], meta=CommandMeta(context_style="bracket"))
  
  @dataclass
  class User:
    id: str
  
  @dataclass
  class Session:
    user: User
  
  arp = alc.parse(
    "test {session.user.id}",
    {"session": Session(user=User(id="123"))}
  )
  assert arp.query[str]("foo") == "123"

改进

• 命令插值的结果现在受类型约束
