This contains two types of re-ordering:
- Internal, putting the focus of each file first.
- Public, re-arranging items and grouping impl blocks to try to better
organize the documentation and find related items.
The main weakness of the docs work is in `Args`. Its just a mess. In
particular, we should probably link the simple casesm like `required` to
the advanced impl block.
Fixes#55
Until we have a modular help generator that can be configured and/or
authored by the users themselves as part of #2914, we will provide the
flexibility of turning off colored help messages but still wanting
colored error messages.
This flexibility was available before #2845 and @dbrgn immediately
noticed it and requested it back to which I agree. This was also
suggested by Josh in
[here](https://github.com/clap-rs/clap/issues/2806#issuecomment-933877438)
Adding in a `StructOpt` derive with `structopt` attributes, with
deprecation notices. Unofrtunately, not as many deprecation warnings as
I would like. Apparently, you can't do them for a `use` of a derive? I
also wanted to inject code that would trigger a deprecation notice for
attributes but that would require enough of a refactor that I didn't
consider it worth it. We are at least providing a transition window
even if it means we'll have to remvoe it next major release without a
deprecation warning.
The intention had been to that people setting this would now set
nothing. Unfortunately, clap2 had `EmptyValues` as the default, so
people were more likely to unset it, making this not work out.
These were broken in #17 and #38 when renaming `hidden` to `hide`. These
weren't caught because we test with `--all-targets` which is mutually
exclusive with `--doc`.
I've been finding I've been setting `AppSettings` without it which is
likely leading to bugs. This tries to raise the visibility by using it
based on the setting being used and not whether the application needs
it.
This both distances itself from our 'require' terminology and aligns
itself with `Option::expect`, making it more likely for people to guess
the intended behavior.
This makes it easier for us to compose. Before, we had to infer things
like "bold" based on the color. Now we just say "error" and get all of
the formatting specific to that.
