New submission from fralau <[email protected]>:
With argparse, an common requirement is is that a user may want to pass a
series of key/value pairs (a sort of equivalent of **args on the command line).
Here is a solution that could be implemented in the standard library with
little effort.
This can be done so, e.g.:
command --set foo=hello bar="hello world" baz=5
With the benefit of experience, this is easy and very intuitive.
This does not require any modification, as the '--set' option can be defined
as:
nargs='+',
metavar="KEY=VALUE"
The next step is to parse the resulting list.
See github gist for a trivial implementation:
https://gist.github.com/fralau/061a4f6c13251367ef1d9a9a99fb3e8d).
It might be useful to integrate a helper method to the standard library
together with an explanation in the doc on how to do it.
