Description
Choice arguments are not printed very nicely with a large number of options.
OPTIONS=[
'option000',
'option001',
'option002',
'option003',
'option004',
'option005',
'option007',
'option001',
'option009',
'option010',
'option011',
'option012',
'option013',
]
arg_board = click.argument('board', type=click.Choice(OPTIONS))
@click.group()
def cli0():
pass
@cli0.command()
@arg_board
def login(board, server):
""" Login to a board """
pass
produces
$ ./test0 login
Usage: test0 login [OPTIONS] BOARD
Error: Missing argument "board". Choose from option000, option001, option002, option003, option004, option005, option007, option001, option009, option010, option011, option012, option013.
Using the textwrapper to separate options by line would make for cleaner and more readable output.
$ ./test0 login
Usage: test0 login [OPTIONS] BOARD
Error: Missing argument "board". Choose from:
option000
option001
...
Also from http://click.pocoo.org/arguments/
Click will also not attempt to document arguments for you and wants you to document them manually in order to avoid ugly help pages.
How does one insert help text for an argument?
Thank you.
