Passing Arguments from Main Commands to Subcommands in Click

Wed, 05 Apr 2023 18:17:37 +0000

If you have command groups in your CLI application so that you have subcommands, you can pass arguments from the group down to the subcommands with the context object. Here’s the pattern:

@click.group()  
@click.argument("arg1", type=click.File("r"))  
@click.option("--option1", default="test")  
@click.pass_context  
def cli(ctx, arg1, option: str):  
    ctx.ensure_object(dict)  
    ctx.obj["arg1"] = arg1  
    ctx.obj["option1"] = option1  
  
  
@click.command()  
@click.argument("subcommand_arg", type=str)
@click.pass_context  
def trigger_training_job(ctx, subcommand_arg):  
    arg1_from_group = ctx.obj["arg1"]

if __name__ == "__main__":  
    cli(obj={})

Using Entry Points in Poetry

If you need to use entry points in a Poetry project, you can use a feature in pyproject.toml for the same behavior as in setuptools. This feature is the heading [tool.poetry.scripts]. Under this, you create the linkage between a command and a function in your script in the form of cmd = "package.module.path:function", giving the fully qualified location of the function using the same dot notation as you would with an import statement.
