想在Options中增加一个所有Commands都可用的--dry选项

bing了一下，发现可以用callback来实现，文档中的例子如下：

import typer app = typer.Typer() state = {"verbose": False} @app.command() def create(username: str): if state["verbose"]: print("About to create a user") print(f"Creating user: {username}") if state["verbose"]: print("Just created a user") @app.command() def delete(username: str): if state["verbose"]: print("About to delete a user") print(f"Deleting user: {username}") if state["verbose"]: print("Just deleted a user") @app.callback() def main(verbose: bool = False): """ Manage users in the awesome CLI app. """ if verbose: print("Will write verbose output") state["verbose"] = True if __name__ == "__main__": app()
