问题 I am trying to accomplish something not very standard for CLI parsing with Click and it only works partially: main CLI has multiple sub-commands (in sample below 'show' and 'check') both those commands might have optional argument, but the argument is preceding them not following I decided to handle that argument in the group "above" it and pass the value in the context Sample: import click @click.group() @click.argument('hostname', required=False) @click.pass_context def cli(ctx, hostname

问题 I want to write a CLI hello that takes a FILENAME as an argument except when the option -s STRING is given, in which case the STRING is processed directly. The program should print hello {NAME} where name is either given via the STRING or taken to be the contents of the file FILENAME. example : $ cat myname.txt john $ hello myname.txt hello john $ hello -s paul hello paul A possible workaround is to use two options: @click.command() @click.option("-f", "--filename", type=str) @click.option("

问题 I am trying to test the raising of exceptions by a command implemented with the Click package. This is my command: @click.option( '--bucket_name', ...) @click.option( '--group_id', ...) @click.option( '--artifact_id', ...) @click.option( '--version', ...) @click.option( '--artifact_dir', required=False, default='downloads/artifacts/', ...) @click.command() def download_artifacts( bucket_name, group_id, artifact_id, version, artifact_dir ): logger.info( f"bucket_name: {bucket_name}, " f"group
