Offset is a more descriptive noun for this argument. This commit also tweaks
the help message for the argument.
This isn't an option/flag, so this change should be transparent to users.
This function doesn't actually need commits, it only needs their IDs. In some
contexts we may only have commit IDs, so there's no need to require an iterator
of Commits.
This commit also adds a `CommitIteratorExt` that makes it easy to convert an
iterator of `&Commit` to an iterator of `&CommitId`.
The type parameter 'C' will be removed from the Template trait, making it
represent a printable type or compiled template.
TemplateRenderer now holds Box<dyn _> template because it's unlikely that the
inner template type can be statically determined.
In short, this enables compilation of template of e.g. Vec<Commit> type by
using CommitTemplateLanguage.
A Template<C> was originally compiled for a specific type C, and invoked as
"Fn(&C) -> _". It was simple and intuitive, but we had to define the context
type C statically. Things got even worse by extensions support because we had
to provide object-safe hook point for each context type C.
This patch basically removes the Context type from compiled templates. The
"self" variable is injected through RefCell<Option<C>> placeholder. A compiled
template knows its "self" type, but the type can be decided per instance, not
per TemplateLanguage type. A drawback is that the "self" variable will have to
be cloned one more time.
The Template<C> abstraction no longer makes sense, and will be split to inner
Template<()> implementations (which usually represent printable types) and the
outer Template<C>.
Users who edit non-head commits usually expect `jj next/prev` to
continue to edit the next/previous commit, so let's make that the
default behavior. This should not confuse users who don't edit
non-head commits since they will simply not be in this state. My main
concern is that doing `jj next; jj prev` will now usually take you
back to the previous commit, but not if you started on the parent of a
head commit.
This prevents rust doctests from trying to compile the code blocks.
I don't think we use doctests much or at all, but I'd like
`cargo insta test --test-runner nextest --accept --workspace`
to pass.
Unfortunately, this affects the output of `jj help` as well, but I
can't think of a workaround for that.
It seems better to have the caller pass the transaction description
when we finish the transaction than when we start it. That way we have
all the information we want to include more readily available.
`RevsetExpression::resolve()` is meant for programmatically created
expressions. In particular, it may not contain symbols. Let's try to
clarify that by renaming the function and documenting it.
