This should already have been done when adding the "View divergence from
upstream" command, but now we're going to add yet another item to the menu that
is unrelated to setting or unsetting the upstream.
So far this hasn't been necessary because all defaults were zero values. We're
about to add the first non-zero value though, and it's important that it is
initialized correctly for users who have a state.yml that doesn't have it yet.
This fixes two minor problems with the prompts:
1. When pressing shift-A in the local commits view, it would first prompt
whether to stage all files, and then it would prompt whether to amend the
commit at all. This doesn't make sense, it needs to be the other way round.
2. When pressing shift-A on the head commit in an interactive rebase, we would
ask whether they want to amend the last commit, like when pressing shift-A in
the files view. While this is technically correct, the fact that we're
amending the head commit in this case is just an implementation detail, and
from the user's point of view it's better to use the same prompt as we do for
any other commit.
To fix these, we remove the confirmation panel from AmendHelper.AmendHead() and
instead add it at the two call sites, so that we have more control over this.
This encapsulates the logic to make sure we have something to commit; which is
to
- auto-stage all files if no files are staged and the SkipNoStagedFilesWarning
config is on
- otherwise, prompt the user whether they want to stage all files
- error out if we don't have any files at all
Of these, the first one was only done when committing with the built-in commit
message panel; there's no reason why it shouldn't also be done when committing
with the editor, or when amending, and now it is.
It implemented this because it wants to do custom truncation of the ref name;
however, we can achieve the same thing by passing the truncated ref name to our
DynamicTitleBuilder, which was previously unused.
Since the slice stores pointers to objects, and we're only modifying the objects
but not the slice itself, there's no need to return it and assign it back. This
will allow us to call the function for subslices of commits.
Also, move the condition that checks for an empty string inside the function;
we're going to call it from more than one place, so this makes it easier.
We will pass these positions back to clients for rendering non-model items, and
it's important that clients can consistently rely on them no matter which
columns were removed.
