The native backend is just a proof of concept and there's no real
reason to use it other than for testing, so let's reduce the risk of
accidentally creating repos using it.
Since the concrete Formatter type is hidden behind the Ui, there wouldn't
be many reasons to use dyn Write at the formatter layer. This allows us
to create a formatter against MutexGuard<Box<dyn Write>> without one more
Box<dyn Write> wrapper.
This should help to create a temporary ColorFormatter instantly.
A cached_colors table could also be shared across formatters, but doing that
would require some locking mechanism. Since commands like cmd_log/diff()
use a single formatter instance, I don't think shared mutable cache would be
needed for the moment.
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.
Previously an expression 'foo-bar-' failed to parse because
1. try first rule: 'foo-bar-' matches (identifier_part+ ~ '-')+, but the
trailing '' doesn't match identifier_part+
2. fall back to second rule: 'foo' matches identifier_part+
=> (identifier 'foo')
Instead, we need to consume as much (identifier_part ~ '-' ~ ...) as possible
before falling back to the identifier_part rule.
I think the trailing + of identifier_part+ is redundant, so removed it as
well.
I had intended for the `features = ["toml"]` to enable *only* the
`toml` feature, but I forgot to disable the default features so it had
no effect. This shrinks the binary from 17.4 MiB to 16.8 MiB.
Let WorkspaceCommandHelper clone it. WorkspaceCommandHelper could return
workspace_id by reference, but doing that would introduce noisy .clone()
calls and lifetime mess.
For consistency with the tree_state handling. This isn't that simple and
concise compared to the tree_state one, so I'm fine to drop the series.
I've extracted {operation_id, workspace_id} pair so these values can be
safely initialized by OnceCell. The extracted struct is named after the
"checkout" file.
As @huyz noticed, I accidentally lost the undo demo in 0d1bf7cb3b. I
also didn't update the working-copy demo. This patch fixes that by
updating all demos, so we also get the recent styling change from
af145c998ea4..
Here OnceCell<T> serves as RefCell<Option<T>>, but it doesn't require runtime
Ref/RefMut wrapper. This allows us to get rid of some .clone() calls needed to
hide Ref<_> from public interface.
I'll make TreeState::snapshot() return a boolean denoting whether tree_state
is updated or not. New tree_id can be obtained from TreeState, so let's
remove it from the return value.
While making tree_state() return RefMut<TreeState> instead of RefMut<Option<_>>,
I felt uncomfortable that tree_state(&self) returned a mutable reference. So
this patch splits it into tree_state() and tree_state_mut().
I was reading a draft of "Git Rev News: Edition 91" [1] where Peff
mentions some unfinished patches to allow negative timestamps in
Git. So I figured I should add support for that before I forget. I
haven't checked if libgit2 supports it, so it might be that our Git
backend still doesn't support it after this patch.

`pkgconfig` has been a alias to `pkg-config` since 2021-01-18, and has started being an error since 2022-09-24.
This commit makes recent nixpkgs versions work, but might make version older than January 2021 break (which is probably not an issue).
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 the remote rejects a push, we now say something like this:
```
Remote rejected the update of some refs (do you have permission to push to ["refs/heads/main"]?)
```
That message could be formatted better, but this seems good enough for
now. We should probably have some more custom conversion from
`GitPushError` to `CommandError` in the CLI layer.
