Like was said in #2435, this is what people would expect.
While we should note this in a compatibility section in the changelog, I
do not consider this a breaking change since we should be free to adjust
the help output as needed. We are cautious when people might build up
their own content around it (like #3312) but apps should already handle
this with `--help` so this shouldn't be a major change.
We aren't offering a way for people to disable this, assuming people
won't need to. Longer term, we are looking at support "Actions" (#3405)
and expect those to help customize the flags. We'll need something
similar for the `help` subcommand.
Fixes#3440
This is a part of #2717
Some settings didn't get getters because
- They are transient parse settings (e.g. ignore errors)
- They get propagated to args and should be checked there
`is_allow_hyphen_values_set` is a curious case. In some cases, we only
check the app and not an arg. This seems suspicious.
This just affects how it's rendered; rather than attempting to highlight
these blocks as a shell script, they'll get highlighted as console
output.
See the rendered versions for a better comparison.
The extra whitespace was targeted at machine processing for a subset of
users for a subset of runs of CLIs. On the other hand, there is a lot
of concern over the extra verbose output.
A user can set the help template for man, if desired. They can even do
something (env? feature flag?) to make it only run when doing man
generation. We also have #3174 in the works.
So let's focus on the end-user reading `--help`. People wanting to use
`help2man` have workarounds to do what they need.
Fixes#3096
This creates distinct tutorial examples from complex feature examples
(more how-tos). Both sets are getting builder / derive versions (at
least the critical ones).
