I thought I was adding a test in #3305. Maybe I considered the
clap_complete changes sufficient for this. Doing more `debug_assert`s
would be good also.
Unsetting `PropagateVersion` helps in some cases but we need to unset it
globally to override the global propagation.
Fixes#3310
This reverts commit 333b993481.
PR #1810's motivation was effectively "this is redundant with `\n`".
That is a fine motivation. Unfortunately, we don't have a way to force
a hard break in `clap_derive`. #2389 should help with this eventually
but we shouldn't hold up 3.0 to get that ready. So in the mean time, we
are restoring `{n}`.
We have #3230 for tracking the re-removal of it.
This allows two overriding args to interact with each other mid-line.
This was broken in 7673dfc / #1154. Before that, we duplicated the override
logic in several places.
Now we plug into the start of a new arg which allows us to do this
incrementally without making the logic complex or inefficient, thanks to
prior refactors.
Fixes#3217
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
We have two ways of fixing this
- Making `--help` work
- Don't put `--help` in the help output
For now, I went with the latter. I tried to make it clear what the
actual requirement is so we can pivot if needed.
Fixes#2892
This happens to also fix the interaction of `DisableHelpFlag` with the
help subcommand and complcations. I've added a test to help catch if we
break this by changing how we fixed the original issue.
Fixes#2724
These issues were reported against clap3. I've not tried to reproduce
these in clap2 to see if they should show up in the release notes.
I'm assuming we won't have a negative performance impact by removing
`impl Copy for Id` because the compiler would inline the `clone()`s and
turn them into copies.
Addresses problems from #3164
This is prep for moving the derive tests. Besides organizing the test
folder for each API, this should reduce link time at the cost of
re-compiling more when a test changes.
