Call another click command from a click command

Question

I want to use some useful functions as commands. For that I am testing the click library. I defined my three original functions then decorated as click.co

Answer 1

Due to the click decorators the functions can no longer be called just by specifying the arguments. The Context class is your friend here, specifically:

1. Context.invoke() - invokes another command with the arguments you supply
2. Context.forward() - fills in the arguments from the current command

So your code for add_name_and_surname should look like:

@click.command()
@click.argument('content', required=False)
@click.option('--to_stdout', default=False)
@click.pass_context
def add_name_and_surname(ctx, content, to_stdout=False):
    result = ctx.invoke(add_surname, content=ctx.forward(add_name))
    if to_stdout is True:
        sys.stdout.writelines(result)
    return result
