I am using click within a local module and I would like to adjust how the help is displayed:
Currently output with --help:
Usage: __main__.py [OPTIONS] COMMAND [ARGS]...
Options:
--help Show this message and exit.
Commands:
foo Foo is a program very nice and pretty...
By default the prog name is __main__.py and the text is trimmed to 78 chars.
I discovered that this can be adjusted using the HelpFormatter class. But I don't know how to use it in this context.
Current Code:
import click
@click.group()
def main(ctx):
pass
@main.command()
def foo():
pass
click.CommandCollection(sources=[main])()
Expected output:
Usage: my_module_name [OPTIONS] COMMAND [ARGS]...
Options:
--help Show this message and exit.
Commands:
foo Foo is a program very nice and pretty and this sentence is very long.
