Why not have two small code blocks rather than a table here?

With a code block it is not possible to link to the individual args, but I'm not sure that's really necessary since there are already links in one of the following tables.

I think the target markup is not necessary. The headings are automatically targets, but the markup to create the link is different (if I remember right):

`:ref:`prog`

This description is not particularly clear.

You should also decide if you want to use 2nd or 3rd person and do it consistently (e.g. this is 3rd, but then you have "indicate" which is 2nd/imperative).

You could use :class:`int` instead of integer.

I would use singular "argument" throughout the table, since add_argument and its options only affect a single argument.

Also ArgumentParser is a class, not a function.

Maybe «Core functionality» was meant.

Review comments haven’t been addressed

@merwok I'm not sure they will ever be addressed, @louisom 's repository is now marked unknown. We could either close this PR, or if you think it still has value I could take over for @louisom

rhettinger · 2019-08-22T05:52:59Z

I think the current state of the patch is hopeless. If some one is inclined to take a more professional pass at this, I think they would be better off starting from scratch.
