[CentralOH] Feedback on a New Package

Thank you for the quick feedback! It's exactly the sort of thing I was
looking for. I've been munching on it the last couple days, thoughts

First -- duh. The instant I looked at the docs after reading your
message, I saw exactly what you're talking about. The links under
"Development" are documents about how to build/test/QA clik itself.
But that is not *at all* clear! (Unless, err... you happened to have
been the one who wrote that section like a month ago and haven't
thought about it much since....)

Second -- sigh. Quickstart/introductory documentation was/is a major
struggle with clik.

> first argument into a function that opens the file

For a real-world program the answer is "just use argparse" -- clik
provides nothing but an extra dependency to hassle with. clik doesn't
really start to help out until/unless the program is more complex
(namely: once it grows subcommands).

So I've felt that, to make a compelling case for clik, the example
code fundamentally has to be complex. That's why the tutorial is
thirteen friggin' steps, and 52m in screencast form.

But that's an unsatsifying answer. Expecting new users to make that
kind of investment of time and mental energy on a first-pass
evaluation is INSANE.

I'm not totally sure what the answer is. But you're right, I need to
bridge that gap.

Also, there is a more specific answer to your example question.
See below :).

import sys

from clik import app, args, parser

def do_a_thing_with_a_filename(filename):

def myapp():
    This sentence and the next will be between the usage statement and
    the argument docs. If you're familiar with argparse, it's the

    All the content after the first blank line is shown after the
    argument docs. In argparse terms, it's the ``epilog``. Note that
    argparse will reformat your documentation, so this is not
    a good place for things like examples that require formatting.

    # Note: The -h/--help argument is automatically added by argparse.
    #       clik provides the ``name`` (for the usage statement),
    #       ``description`` and ``epilog`` to argparse. Description
    #       and epilog are taken from the function docstring, as
    #       described above. The ``name`` defaults to the function's
    #       name, but can be overridden by calling the decorator as
    #       follows: @app(name='other-name')

        help='filename to pass to the function',


    if args.filename is None:
        print('please provide a filename', file=sys.stderr)
        yield 1


if __name__ == '__main__':

Thanks again for your feedback!
