Adding "found" might seem minor but I feel it has a slight softening on the message. It also maintains scanability as it is at the end and short.
As this is a one-off message change and not a styling issue to be consistent with, I think this is safe to put in a patch release.
This let's you get an arguments values, grouped by the occurrence of the
argument.
Note: this does not stablize derive support. That requires a blocking
change and can be enabled via `unstable-v5` flag. See #4626 for an
exploration of how we can make this easier in the future.
Fixes#2924
In text communication you need to balance
- Scannability, putting the most important information upfront
- Brevity so people don't get lost in the message
- Softness to help ease people through a frustrating experience
I feel we weren't doing great on the first two points, so tried to
iterate on the messages to improve them. I hope we aren't suffering too
much on the third point as a side effect.
This is an intermediate solution for #4408. As there were no agreeed
upon goals, I went with what I felt read well and that I saw commonly
used on non-clap commands.
- "information" isn't really a necessary word.
- I originally favored `Print this help` but realied that doesn't read
correctly in completions.
- Besides being shorter, the reason for the flipped short/long hint is
it gives people the context they need for scanning, emphasizing
"summary" and "more".
Fixes#4409
Similar to
- Listing all required arguments when one is missing
- Listing all possible values when no value is provided
This came up when discussing #3572
Making this plural can go either way as
- Clarify it is plural
- This is all really to simulate actually doing subcommands and you only
do one at a time
For now, I lean towards clarifying it is plural
I also tweaked the message to be more consistent with how `--help` and
`-h` describe themselves.
Fixes#4342
In clap v4, we changed the padding from 4 to 2 but we didn't update our
calculation for when to switch to next-line-help as it was a magic
number (we tried to catch all of these).
When updating the tests, we also missed that a test was being wrapped
too narrowly
This was found while discussing #3300

Inspired by #2766
This will fix `clap_derive`s behavior for optional-flattened groups as
it will properly detect when the group is present (#3566).
While I consider this a bug and not part of compatibility guarentees, I
still want to keep in mind user impact which could still prevent this.
Defaults will make the group always-present which has little value and
if anything is relying on this, it is probably an application bug.
When overriding other fields, help or version flag, globals, etc, a user
might not care about the value, so let's ignore the lookup.
Been talking about this for a while but Issue #4367 moved this forward
because there wasn't a good way to handle this without changing
behavior.
