We only want to do this when the function is called from the remote branches
panel. It can also be called with a selection of local branches in order to
delete their remote branches, but in this case the selection shouldn't be
collapsed because the local branches stay around.
We had code already that was supposed to do this, but it didn't work. It should
have used SetSelection() instead of SetSelectedLineIdx(); the latter doesn't
actually cancel a range selection.
Introduce a new function specifically for collapsing the range after deleting
multiple items, so that clients don't need two calls (we'll add a bunch more in
this branch).
While it's true that the behavior is a little different from the staging panel,
where the staged lines are actually removed from the view and in many cases the
selection stays more or less in the same place, it is still very useful to move
to the next stageable thing in the custom patch building view too.
This improves the experience when selecting a hunk generously with the mouse, by
dragging over it including some context lines above and below. Previously we
would consider the "moving end" of the selection range for whether things need
to be added or removed, but this doesn't make sense if it's a context line. Now
we consider the first actual change line that is included in the range.
It is confusing to get header lines, hunk headers, or context lines rendered as
being included in a custom patch, when including these makes no difference to
the patch.
This is only a visual change; internally, we still record these non-patch lines
as being included in the patch. It doesn't matter though; you can press space on
a header line and nothing happens.
It would probably be cleaner to only record + and - lines in the includedLines
array, but that would be a bit more work, and doesn't seem worth it.
CheckMergeOrRebase calls Refresh already. However, it does an async refresh by
default, so we must turn this into a sync refresh so that moving the selection
down by one works even for the very first commit in history. Also, we must add
an explicit call to FocusLine so that the view selection is in sync with the
model selection; previously this was taken care of by the PostRefreshUpdate call
that happens as part of a refresh.
Keep the same commit selected, by moving the selection down by the number of
cherry-picked commits. We also do this when reverting commits, and it is
possible now that we use a sync waiting status.
We also need to turn the refresh that happens as part of CheckMergeOrRebase into
a sync one, so that the commits list is up to date and the new selection isn't
clamped.
We are about to change the selection behavior when cherry-picking, and it's good
to have tests that document in what way it changes in the next commit.
For the case of creating a new branch by moving commits to it, we were using the
current (old) branch name in the stash name; change this to use the new name
instead.
Unlike moving a patch to the index, applying or reverting a patch didn't
auto-stash, which means that applying a patch when there's a modified (but
unstaged) file in the working tree would error out with the message "error:
file1: does not match index", regardless of whether those modifications conflict
with the patch or not.
To fix this, we *could* add auto-stashing like we do for the "move patch to
index" command. However, in this case we rather simply stage the affected files
(after asking for confirmation). This has a few advantages:
- it only changes the staging state of those files that are contained in the
patch (whereas auto-stashing always changes all files to unstaged)
- it doesn't unnecessarily show a confirmation if none of the modified files are
affected by the patch
- if the patch conflicts with the modified files, the conflicts were "backwards"
("ours" was the patch, "theirs" the modified file); it is more logical if "ours"
is the current state of the file, and "theirs" is the patch.
It's a little unfortunate that the behavior isn't exactly the same as for "move
patch to index", but for that one we do need the auto-stash because of the
rebase that runs behind the scenes.
The tests show that this currently fails with the confusing error message "does
not match index", regardless of whether the patch conflicts with the
modifications or not. We'll improve this in the next commit.
I don't bother adding tests for reverting a patch, as the code is basically the
same as for apply.
This is functionality that works already, we only add the test for more complete
test coverage. However, there's a detail problem, and the test demonstrates
this: we keep the stash even if there was no conflict. We'll fix this next.
Refresh is one of those functions that shouldn't require error handling (similar
to triggering a redraw of the UI, see
https://github.com/jesseduffield/lazygit/issues/3887).
As far as I see, the only reason why Refresh can currently return an error is
that the Then function returns one. The actual refresh errors, e.g. from the git
calls that are made to fetch data, are already logged and swallowed. Most of the
Then functions do only UI stuff such as selecting a list item, and always return
nil; there's only one that can return an error (updating the rebase todo file in
LocalCommitsController.startInteractiveRebaseWithEdit); it's not a critical
error if this fails, it is only used for setting rebase todo items to "edit"
when you start an interactive rebase by pressing 'e' on a range selection of
commits. We simply log this error instead of returning it.

I don't understand what "cancel on the next popup" means; there is no further
popup after this code.
I took the set of enabled checks from revive's recommended configuration [1],
and removed some that I didn't like. There might be other useful checks in
revive that we might want to enable, but this is a nice improvement already.
The bulk of the changes here are removing unnecessary else statements after
returns, but there are a few others too.

The function would return "head/branchname" when there was either a tag or a
remote with the same name.
While fixing this we slightly change the semantic of the function (and of
determineCheckedOutBranchName, which calls it): for a detached head it now
returns an empty string rather than the commit hash. I actually think this is
better.
