This allows callers to instantiate long-lived formatter. ui.write() can't
be invoked while formatter is borrowed. My plan is to make Ui directly hold
output streams so the color settings can be easily reset.
ui.stdout/stderr_formatter() will create a temporary formatter there.
write_commit_summary() could be hosted by WorkspaceCommandHelper to eliminate
some of the function arguments, but that would make the source RepoRef unclear
while transaction is in progress.
Let WorkspaceCommandHelper clone it. WorkspaceCommandHelper could return
workspace_id by reference, but doing that would introduce noisy .clone()
calls and lifetime mess.
I changed the "GLOGAL OPTIONS" help heading to use title case, to
match clap's new help style.
I also removed our override of the help text for `-h, --help` because
the default text now includes "(use `-h` for a summary)" (and it's
harder override now).
Perhaps the most obvious difference to users will be the changed help
output
(https://epage.github.io/blog/2022/09/clap4/#polishing-help-output). It
no longer has color, and long lines are not wrapped. I suppose we
should wrap the text ourselves instead..
When we resolve aliases and we try to resolve something that is not a
real command and not an alias, we currently replicate `clap`'s error
message. I don't know why I did that because it seems that we should
just stop resolving aliases and let `clap` try to parse what we have
resolved at that point. This patch makes that change, thereby removing
an additional call to `process::exit()`.
In many of these places, we don't need an owned value, so using a
reference means we don't force the caller to clone the value. I really
doubt it will have any noticeable impact on performance (I think these
are all once-per-repo paths); it's just a little simpler this way.
This commit moves much of the `commands` module that isn't specific to
a particular command into a new `cli_util`.
Much of this is actually not even CLI-specific, so we should move that
further down into the library, but that can come later. That includes
the code in `WorkspaceCommandHelper` for snapshotting the working copy
and automatically importing/exporting to a colocated Git working copy.
