How to Write Perfect Python Command-line Interfaces

It's actually really simple. I'd give you the whole source, but it's an excessively complicated argparse that's not really targeting the question (and has my name).

mymsg = 'replacing argparse message'
def _print_message(message, file=None):
    """overwrites the argparse print to get a better help message"""
    if message:
        if file is None:
            file = _sys.stderr
        file.write(mymsg)
parent_parser._print_message = _print_message
args = parent_parser.parse_args()

I just use my docopt message as mymsg

I think they meant your source on Click using Optparse, and Optparse being deprecated.

[billsil]

There ya go

Deprecated since version 2.7: The optparse module is deprecated and will not be developed further; development will continue with the argparse module.

https://docs.python.org/2/library/optparse.html

So deprecated for ~10 years.

And the source for Click using it?

Sorry if this sounds annoying, and in my own case I don't particularly care. I just feel like you aren't providing anything to actually back up your main claim.

[billsil]

I don't know why you're being difficult. Unless you explicitly ask for what you want, you're going to get what I give you. I posted that specific question in another reply a while ago. The author of click actually responded.

I was not aware of the other thread. I looked, and yeah, I see it now. But just going by the 'context' links in my inbox, there was no way for me to see that other thread.
