Robert Benson <derelbenkoe...@gmail.com> added the comment:
What I'm talking about is reading a single arg (of a dictionary or collection
type) that can be split across multiple lines, rather than a single line
containing multiple args
My motivation was that reading args from a file should behave in a manner
similar to other command-line utilities, such as the `-d` option for `curl` and
the `-e` option for `ansible`. These take the entire file you give it and store
it as one dictionary or object, not by merging it with the rest of the
namespace but by taking the dictionary as the value of just that arg. So:
argument_parser.add_argument("-d", "--data", type=argparse.JsonType) # just
for example
if I call the program with `--data @foo.json`
I want argument_parser.parse_args().data to be the dict that is in foo.json,
whether foo.json is pretty-printed or not.
I haven't done an exhaustive search of StackOverflow, but seeing a couple top
answers indicated that this was not readily available without the user at least
having to call `json.loads` on a string argument themselves, when it seems
logical that it would be built into the library to parse the json into a
dictionary
