When pasting a multi-line commit message into the subject field of the commit
editor, we would interpret the first newline as the confirmation for closing the
editor, and then all remaining characters as whatever command they are bound to,
resulting in executing all sorts of arbitrary commands.
Now we recognize this being a paste, and interpret the first newline as moving
to the description.
Also, prevent tabs in the pasted content from switching to the respective other
panel; simply insert four spaces instead, which should be good enough for the
leading indentation in pasted code snippets, for example.
Jesse's comment from https://github.com/jesseduffield/lazygit/issues/4237:
We recently added a new option to check out a commit's branch from within the
commits, reflog, and sub-commits panels:
https://github.com/user-attachments/assets/0a5cf3f2-6803-4709-ae5a-e4addc061012
After using it for some time, I find it annoying that the default option has
changed. I rarely find myself wanting to check out a branch from the commits
panel, and it's rarer still to want to check out a branch from the reflog and
sub-commits panel. Although there may be use cases for this, it is jarring that
something you can always do (checkout the commit) is harder to do than something
that you can sometimes do (checkout the branch).
We've also had a user complain (see
https://github.com/jesseduffield/lazygit/pull/4117) about their muscle-memory
being broken by the recent change, and I have also fallen victim to this. I
don't think that the new branch checkout option is sufficiently useful to
dislodge the existing keybinding, so let's swap them.
The code that tries to reselect the same branch again uses GetItems, which in
case of filtering is the filtered list. After replacing the branches slice with
a new one, the filtered list is no longer up to date, so we must reapply the
filter before working with it. It so happens that refreshView does that, so
simply call that before setting the selection again; I don't think the order
matters in this case. Otherwise we'd have to insert another call to
ReApplyFilter before the call to GetItems, which we can avoid this way.
Note that this doesn't actually make anything work better in the case of
deleting a branch, since we can't reselect the deleted branch anyway of course.
But it avoids a possible crash if the branch that was deleted was the last one
in the unfiltered list.
This includes the "only conflicting" status that the user can't switch to
themselves. We display it anyway to give a hint that files are being filtered,
and to let them know that they can turn the filter off if they want to.
I renamed the "Reset filter" item to "No filter" to make it look more like a
state than an action, so that it fits the radio button concept better.
When there are conflicts and we set the filter to show only conflicting files,
then none of the radio buttons light up, which is slightly strange. I guess it's
ok though.
We don't need to maintain additional state to allow this; all we need to do is
take over the filter only when the number of conflicting files goes from zero to
non-zero, rather than every time it is non-zero.
The only problem is that we don't allow users to go back to showing only
conflicted files, but that's just because we don't have that as an entry in the
menu. And I don't think it's a problem.
This handles the situation where the user's own config says to not show
untracked files, as is often the case with bare repos managing a user's
dotfiles.
Git diff and patch doesn't work reliably with a context size of 0, so disable it
in this case (and discarding changes as well). Magit does the same, see
https://github.com/magit/magit/issues/4222.
Staging entire files by pressing space in the Files panel is still possible, of
course.
When pushing a branch that didn't have an upstream yet, we use the command line
git push --set-upstream origin HEAD:branch-name
The HEAD: part of this is too unspecific; when checking out a different branch
while the push is still running, then git will set the upstream branch on the
newly checked out branch, not the branch that was being pushed. This might be
considered a bug in git; you might expect that it resolves HEAD at the beginning
of the operation, and uses the result at the end.
But we can easily work around this by explicitly supplying the real branch name
instead of HEAD.
For editable views it is important to actually show the blank line so that we
can put the cursor there for typing.
This fixes problems with adding blank lines at the end of longer commit
messages.
There are two ways to jump to the editor on a specific line: pressing `e` in the
staging or patch building panels, or clicking on a hyperlink in a delta diff. In
both cases, this works perfectly in the unstaged changes view, but in other
views (either staged changes, or an older commit) it can often jump to the wrong
line; this happens when there are further changes to the file being viewed in
later commits or in unstaged changes.
This commit fixes this so that you end up on the right line in these cases.
When the user checks out a commit which has a local branch ref attached
to it, they can select between checking out the branch or checking out
the commit as detached head.
Sometimes we populate the commit message panel with a pre-created commit
message. The two cases where this happens is:
- you type `w` to commit, in which case we put the skipHookPrefix in the subject
- you have a commitPrefix pattern, in which case we match it against the branch
name and populate the subject with the replacement string if it matches
In either case, if you have a preserved commit message, we use that.
Now, when you use either of these and then cancel, we preserve that initial,
unchanged message and reuse it the next time you commit. This has two problems:
it strips spaces, which is a problem for the commitPrefix patterns, which often
end with a space. And also, when you change your config to experiment with
commitPrefix patterns, the change seemingly doesn't take effect, which can be
very confusing.
To fix both of these problems, only preserve the commit message when it is not
identical to the initial message.
So far, lines in the view corresponded 1:1 to lines in the patch. Once we turn
on wrapping for the staging view (which we don't do yet), this is no longer
true, so we need to convert from view lines to patch lines or vice versa all
over the place.
to make it more generally usable by clients other than ConfirmationHelper, which
we will do later in this branch. Rename it to WrapViewLinesToWidth while we're
at it.
Add tests; in particular, add a sanity check that we wrap lines the same way as
gocui does. The tests that are added here are the same ones as in gocui for its
lineWrap function, but we'll extend them a bit in later commits in this branch.
This is also what we do in the staging controller, and it makes it so that when
you exit the patch building view and then enter it again (for another file, or
the same one) we select the first hunk again.
For non-merge commits we change "pick" to "drop" when we delete them. We do this
so that we can use the same code for dropping a commit no matter whether we are
in an interactive rebase or not. (If we aren't, we could just as well delete the
pick line from the todo list instead of setting it to "drop", but if we are, it
is better to keep the line around so that the user can change it back to "pick"
if they change their mind.)
However, merge commits can't be changed to "drop", so we have to delete them
from the todo file. We add a new daemon instruction that does this.
We still don't allow deleting a merge commit from within an interactive rebase.
The reason is that we don't show the "label" and "reset" todos in lazygit, so
deleting a merge commit would leave the commits from the branch that is being
merged in the list as "pick" commits, with no indication that they are going to
be dropped because they are on a different branch, and the merge commit that
would have brought them in is gone. This could be very confusing.
Not much of a change in behavior, because moving merge commits was already not
possible. However, it failed with a cryptic error message ("Todo fa1afe1 not
found in git-rebase-todo"), so disable it properly instead.
It is needed by both call sites of this function. This has the added benefit
that the argument doesn't unnecessarily show up in the status view when diffing
mode is on.
In 67b8ef449c we changed the "edit" command to insert a "break" after the
selected commit, rather than setting the selected todo to "edit". The reason for
doing this was that it now works for merge commits too.
Back then, I claimed "In most cases the behavior is exactly the same as before."
Unfortunately that's not true, there are two reasons why the previous behavior
was better (both are demonstrated by tests earlier in this branch):
- when editing the last commit of a branch in the middle of a stack of branches,
we are now missing the update-ref todo after it, which means that amending the
commit breaks the stack
- it breaks auto-amending (see the added test earlier in this branch for an
explanation)
For these reasons, we are going back to the previous approach of setting the
selected commit to "edit" whenever possible, i.e. unless it's a merge commit.
The only scenario where this could still be a problem is when you have a stack
of branches, and the last commit of one of the branches in the stack is a merge
commit, and you try to edit that. In my experience with stacked branches this is
very unlikely, in almost all cases my stacked branches are linear.
We allow deleting remote branches (or local and remote branches) only if *all*
selected branches have one.
We show the a warning about force-deleting as soon as at least one of the
selected branches is not fully merged.
The added test only tests a few of the most interesting cases; I didn't try to
cover the whole space of possible combinations, that would have been too much.
Since we want to select multiselections, this will make it easier to pass a
slice of remote branches. It does require that for the case of the local
branches panel we need to synthesize a RemoteBranch object from the selected
local branch, but that's not hard.
