Stefan HallerandClaude Opus 5 3cfdd0cd2d Show a selection only over the diff the panel offers
Some merge conflicts can only be resolved by picking a side. The files
panel explains those rather than diffing them, and where one side deleted
the file and the other modified it, git's diff of that modification is
shown below the explanation. The focused main view took those change lines
for a diff of its own. It drew a selection over them and offered to stage
hunks of a file whose conflict staging can't resolve.

So have a render say whether it holds the diff the panel offers in the
main view, and put a selection only on one that does. Every diff render
already goes through NewMainViewDiffTask, so it says so for itself; the
custom patch preview, assembled as text rather than run as a command, says
so through NewMainViewDiffStringTask. Establishing a selection asks the
pane the same question rather than looking for change lines itself.

The selection has been wrong over this content since "Show a selection in
the focused main view" introduced it, and the fix belongs there. It lands
here instead because a render had no way to say what it holds until "Show
git's own diff when the renderer's can't be acted on" gave every diff
render one constructor to go through.

Stefan HallerandClaude Opus 5 e4bb7e6dc6 Show git's own diff when the renderer's can't be acted on
A diff renderer may lay a diff out however it likes: line numbers in a
gutter, the +/- column replaced by colour, the two sides in columns. Once
it has, we can only tell which line of which file a row shows if the
renderer says so. Under a renderer that doesn't say, the main view holds
a diff that can be read but not staged, edited or copied from. That is no
good now that the main view is where you stage.

So focusing it brings git's own diff instead, and every re-render while it
stays focused keeps to that, so staging a hunk doesn't flip back. Browsing
is untouched: you see what the renderer produced until you focus the view
to act on it.

Whether the renderer says anything is settled by asking it rather than by
watching it work: run it on empty input and see whether it announces the
protocol. Announcing is a property of the renderer, so the answer is known
before we render anything, and a diff with no lines to describe can't fool
it. Watching would have to see a diff go by first, and a binary file's diff
holds nothing that would tell the two cases apart. The answer is remembered
until the renderer changes. git itself is asked the same question, with the
renderer's own arguments, since it announces itself for exactly the formats
whose output can't be read back as a diff.

Stefan HallerandClaude Opus 5 e5fa336c1a Commit and find a fixup base from the focused main view
Staging in the main view leaves you looking at the working tree's diff with
everything you meant to stage in the index — and, until now, having to go
back to the files panel to commit it. The commit keys, and the one that
finds the commit a fixup belongs to, are offered there too, so that the
whole staging-to-committing round happens in one place.

They act on the working tree, which the main view only sometimes shows, so
they do nothing over a commit's or a stash's diff — browsing history can't
commit by accident — and are listed only where they do something. The check
happens per press: what the main view is showing changes as the user moves
about, while the bindings are registered once.

Stefan HallerandClaude Opus 5 985b2a2736 Discard the selected diff lines from the focused main view
The remove key now works on a diff selection the way it does in the staging
view: on the unstaged side it throws the selected lines away, which it asks
about first, and on the staged side it takes them out of the index, which is
unstaging and needs no warning.

It goes through the same path as staging, so that everything around the
action behaves identically — the selection lands on the change that took the
place of the discarded one, and the focus follows the side it acted on.

Stefan HallerandClaude Opus 5 a5dfc78f82 Carry the acted-on lines into the pane the work lands in
Each side of a file's diff has a pane of its own, but a pane is only shown
while its side has something in it: staging the last unstaged change takes
the upper pane away, and unstaging the last staged one takes the lower one
away. The focus follows into the pane that is left, and the selection has to
be waiting there when it arrives — on the lines just acted on, which is where
they are now, unless they were discarded rather than moved, in which case on
what is left of the file. The pane being moved to shows no selection until
the restore places one, so that the selection it was left with the last time
it was used doesn't appear for a frame.

Whether the acted-on side still holds anything is a question the model can't
answer: a refresh only queues its update, and by the time it lands the
re-render this has to ride is already under way. So the answer is worked out
from what we just did — the files we changed report whether the selection
covered all of their changes, and the ones it didn't touch are as the model
describes them.

Stefan HallerandClaude Opus 5 1f3f29a9ab Leave a pane that only the permanent split keeps around
Configured to always split the diff, a pane is shown whether or not its side
of the file holds anything, so emptying the side the focus is on no longer
takes the pane away — but it does take away everything there was to do there,
which is the question the focus is really asking.

So the render says which of the panes it is giving something to act on,
rather than the focus reading that off which panes are shown.

Stefan HallerandClaude Opus 5 739412cd5f Follow the focus into the pane that is left
Each side of a file's diff has a pane of its own, and a pane is only shown
while its side has something in it. So anything that empties the side the
focus is on takes that pane away with it: committing what was staged, or a
commit or a discard happening outside lazygit and arriving with a refresh.
The focus was left on a pane that isn't there any more, where the next
keypress acted on nothing.

The render is what decides which panes are shown, so the question is asked
there, of every render rather than of the handful of actions that could think
to ask it themselves. The pane the focus moves into gets its selection once
that render has finished and there is something to put one on, the way
focusing it by hand would — and shows none until then, so that the selection
it was left with the last time it was used doesn't appear for a frame.

Stefan HallerandClaude Opus 5 c4a7978dd4 Carry the selection to the next change after staging
Staging takes the lines it acted on out of the diff, so the selection has
nothing to sit on afterwards and would be left wherever those lines used to
be. What the user wants is the change that moved up into their place, so
that pressing the key again goes on to the next one — which is how staging
line by line through a file works.

The line acted on is gone, so it can't be remembered by identity the way a
re-render of the same diff remembers one; what is remembered instead is its
place in the sequence of the diff's changes, which the change after it
inherits. Staging the last change is the one case with nothing to inherit
it, and there the selection stays on the last change there is.

Stefan HallerandClaude Opus 5 7b912d2f51 Act on a whole file's changes as acting on the file
The diff of a deleted file is its content going away, so putting every
line of it into the index leaves an empty file there (modified in the
index, deleted in the working tree) rather than the deletion the user
selected. The reverse case matches: the diff of an added file is its
whole content, and taking all of it back out of the index leaves the file
tracked and empty rather than untracked again. In the staging view you
had to enter such a file deliberately to reach these cases, but stepping
through a directory's diff hunk by hunk runs into them routinely.

Selecting every change of a file says "this file", so stage or unstage
the file itself. This applies to any file, since applying a file's whole
diff amounts to the same thing everywhere else.

Stefan HallerandClaude Opus 5 d514cd400c Stage and unstage diff lines from the focused main view
Space in the focused main view now acts on the selected lines the way it
does in the staging view: over the working tree's unstaged changes it puts
them into the index, and over the staged ones it takes them back out. Which
of the two it does is a property of the pane, each side of the diff having
one of its own. Nothing has to be entered first, and a selection reaching
across several files of a directory's diff is applied as one patch per file.

The rows on screen are only a picture of the diff, so the patch is built
from the diff itself: each selected row's identity — which file, which line
of it, and whether it is a deletion — is looked for in the file's own diff,
and the lines that match are the ones the patch includes. Matching by
position rather than by counting rows is what tells the two halves of a
modified line apart, since the deletion and the addition replacing it sit at
the same place in the new file.

Panels other than the working tree offer no action on their diff yet, so
space says nothing and does nothing there.

Stefan HallerandClaude Opus 5 33e53a7579 Copy the selected diff lines from the focused main view
The main view shows a diff renderer's picture of a diff, and that is not
what you want on your clipboard: a renderer may drop the +/- column, move
the line numbers into a gutter, group a hunk's deletions before its
additions, or leave lines out altogether. So copying takes the lines from
the diff itself, locating them by the identity of the selected rows.

Only the panel that produced the diff can produce it again, though: the
working tree's staged or unstaged side, a commit's, a stash entry's. The
new seam is there for that. It asks per file, so that copying three lines
of a commit's diff doesn't fetch the whole of it, and it will grow the
actions on a selection as staging and patch building arrive.

The clipboard gets the run of diff lines from the first selected line of
a file to the last, so that lines the renderer hid come along and the
result still reads as a diff. Headers count as selected lines too. A hunk
header names the first line of its hunk, so it is looked for the way a
line of the file is. A file header names no line at all, and a rendering
may draw it over any number of rows, so a selection touching one of them
takes the whole header.

As in the patch explorers, a selection that is all additions or all
deletions loses its +/- column, ready to be pasted into code. One that
reaches into a header keeps the columns, and what comes out is a patch
fragment rather than lines of code.

Stefan HallerandClaude Opus 5 55752f8ba7 Always show a file's staged changes in the lower pane
Which pane a side of a file's diff appeared in depended on what else the file
had: the staged side had the lower pane while there were unstaged changes
above it, and took over the upper one when there weren't. So the same content
moved about, and which side a pane was showing was something the code had to
work out from the file's status rather than knowing from the pane.

Now each side has a pane of its own — unstaged above, staged below — shown
when there is something on it. A file with nothing unstaged shows its staged
changes in the lower pane alone, which then has the whole space, including
the label of the key that focuses it.

Nothing about this is visible to the user: the same diff appears in the same
place, with the same title and the same label, and the same keys focus and
scroll it. What it is for is the code, which no longer has to ask the file
what a pane is showing — and, once the diff can be staged from, no longer has
to make one key mean opposite things in the same pane.

Stefan HallerandClaude Opus 5 636832e045 Let an emptied main pane forget what it was showing
A pane that has been emptied is showing nothing, but it kept the scroll
position it was left at and went on claiming the render it used to show,
so the next render into it — the same command's output, the file it was
showing being selected again — counted as content the view already had,
and was revealed partway down.

So say what the empty pane is: at the top, and showing nothing that a
render can be a re-render of.

Stefan HallerandClaude Opus 5 2236c8d8d9 Add a test for a main pane coming back after being emptied
A pane the render has nothing to show is emptied, but keeps the scroll
position it was left at and its claim to the render it was showing. So
when it comes back — the file it was showing before is selected again —
its content is rendered under the same command it already had, which is
taken for the content the view is showing, and the user is left partway
down a diff they have only just been given.

Stefan HallerandClaude Opus 5 ed7ab3ac26 Keep both ends of a selected range across a re-render
A range or hunk selection covers a stretch of the diff, and restoring only
the cursor left the other end pointing at whatever line the new rendering
happened to put there — with more context lines above, a selected hunk
would grow a tail of context it never covered.

So the other end is remembered by identity too, and put back before the
cursor. If it is a line the re-render dropped, the selection is left as the
single line we landed on: there is no telling which line inherits a
selection's edge, and a wrong guess acts on lines the user never chose.

Stefan HallerandClaude Opus 5 02e873d1fe Keep your place in the diff when ignoring whitespace
Ignoring whitespace is how you ask whether what you are looking at is more
than reindentation, so being dropped at the top of the diff is a poor
answer: you have to find your way back to the change you were asking about
to see what became of it.

Unlike the other ways of re-rendering a diff, this one can take the line
you were on away for good, along with the hunk or even the file it was in.
When it does, the view lands on the nearest line the diff kept, wherever in
it that is — the walk of fallbacks doesn't stop at the file's edge, since a
file of nothing but reindentation leaves nothing nearer to land on. And
when ignoring whitespace empties the diff altogether, there is nothing to
keep and the view simply shows what is left.

A whitespace-only change that shares a hunk with a real one is a happier
case: it is shown as a context line rather than as a change, but it is
still the same line of the same file, so we stay on it.

Stefan HallerandClaude Opus 5 9ec77382cc Keep your place in the diff when switching diff renderers
Cycling through the diff renderers is for comparing how they show the same
change, which is hard to do from the top of the diff each time. The line
you were on is the same line of the same file whichever renderer draws it,
so the restore finds it again — by the records a renderer states, where it
speaks the protocol, and by parsing its output as a diff otherwise.

The restore sits in DiffHelper.RenderToMainAgain. A switch between a
dark and a light terminal background renders the diff again through the
same helper, so it keeps your place as well.

Stefan HallerandClaude Opus 5 20625407d6 Keep your place in the diff when changing the context size
Pressing { or } re-rendered the diff with less or more context around each
change and dropped you back at the top of it, so finding your way back to
what you were reading was on you.

Remember where the view is before triggering the re-render, and have the
restore put it back there. The line to remember is the selected one when a
selection is showing, and the middle visible line otherwise — what you are
looking at, rather than the view's top edge. It is remembered by identity,
because the new rendering puts it on a different line of the view, and it
is found again by the records a diff renderer states for its rows, or by
parsing the rendering as a diff where it still looks like one.

The line may not be there at all afterwards: shrinking the context takes
context lines away. So the lines around it come along as fallbacks, nearest
first, and the view lands on the nearest one that survived, put back on the
screen row it was on — leaving what you were reading where it was, give or
take the line that went. The walk that collects them covers the whole diff
rather than stopping at the nearest change on either side: those always
survive a context-size change, but not everything a re-render can do to a
diff is that considerate.

Under a diff renderer that says nothing about its rows there is nothing to
look for at all, and the view is left at the offset it had instead: often not
the line it was on, but always closer to it than the top of the diff. That is
what the re-render asks for besides the restore, since it is a different
command from the one that produced what is on screen and would otherwise be
taken for a diff the user has never seen.

Stefan HallerandClaude Opus 5 0a8f7a8262 Follow the selection with the search in the focused main view
Search the diff, then move the selection with the arrow keys, and
pressing "n" goes to the match after the one the search was last on
rather than to the one after the selection. So walking through the diff
and then picking up the search where you got to takes as many presses as
there are matches behind you.

List views and the staging view keep the current match in step with their
selection; do the same here.

Stefan HallerandClaude Opus 5 ec02df73cb Edit the selected line of a diff from the focused main view
Reading a diff is often how you notice something to fix, and the file and
line are right there in front of you — so pressing edit opens the file at
the line under the selection, as it does in the staging view.

The line number the diff shows is the line number in the version the diff
is of, which for a commit's diff is not where that line sits today, so it
is carried forward the same way clicking a diff-renderer hyperlink already
does. A file header names no line, so it just opens the file.

Stefan HallerandClaude Opus 5 e583bded5d Jump by hunk and by file in the focused main view
Reading a diff of any size means moving in bigger steps than a line at a
time, which the staging view offers and the main view didn't. So the same
hunk keys work here, and n / N step from file to file — worth having only
here, since a diff spanning several files is something the staging view
never showed.

Where "the next file" begins isn't in the text: a diff renderer may print
whatever it likes above a file's content. So navigation lands on the first
row that states which file it belongs to, which is the file's header when
the source says so and its first content line otherwise. The anchor's own
file is found by scanning down rather than to the nearest row either way —
having just landed on a header, the nearest row above belongs to the file
we came from, and taking it would send the next press back where we
started.

A file you go to is brought to the top of the view, since the file is what
you went there for and the more of it is on screen the better. That only
applies where the view has to scroll at all: a file already on screen
leaves it where it is. In hunk mode what ends up selected is the file's
first change rather than the row the file begins at, and a large context
size can put that change further down than a screenful; the selection is
scrolled into view afterwards as any other jump's is, and the alignment
gives way where the two can't both hold.

The diff loads lazily, so a target below the loaded portion isn't there to
be found; rather than doing nothing, we read the rest in and look again.

Stefan HallerandClaude Opus 5 c7a5276d11 Select a range of diff lines by dragging
Selecting a range with the mouse is the obvious gesture once clicking
selects a line, and it's the only way to get a range without knowing the
keybindings.

The range has to be anchored where the mouse went down, which the view
can't tell us: a click in hunk mode selects a whole block, leaving the
view's own range anchor at the block's far end, so a drag from there would
grow the selection from the wrong end. So the clicked line is remembered
when the click happens, and the drag anchors there.

A drag that reaches the edge of the view keeps scrolling, using the same
autoscroller the staging view does — mouse capture means the pointer can be
dragged past the edge, and there is more diff down there than fits on
screen. Unlike the staging view, whose content is a string that is always
there in full, this diff loads lazily, so scrolling down has to keep
reading it in or the autoscroll would stop at the loaded edge.

Stefan HallerandClaude Opus 5 a76fe1a2b9 Select a whole change block when focusing the main view in hunk mode
Users who set hunk mode as their default get it when entering the staging
view, and the focused main view is on its way to replacing that view, so it
has to behave the same: focusing selects a whole change block, and clicking
a change line selects that line's block, ready to act on. A click on a
context line still selects only that line, since the click points at it
precisely — you may well want to edit it. A click inside the block that is
already selected does the same, giving hunk mode up and going back to line
by line. That keeps a single line reachable with the mouse in a block too
long to see the end of, and matches how a click inside a range selection
already collapses it.

The block offered up is the first one that begins on screen, so that its
whole extent can be seen before acting on it. Only when none does — a change
too long to fit on the screen — is the block that reaches into the view from
above taken instead, and the selection then extends to its first line off
screen: focusing a diff must not move it, so nothing here scrolls.

The staging view makes one exception, and so must we, or a file that is one
solid block of changes (a file you just created, or deleted) would come up
with all of it selected. The staging view asks the parsed patch; we ask the
rendered diff the same question, which needs no second git invocation and
works over a whole commit's diff, where the answer differs per file.

Stefan HallerandClaude Opus 5 831ff5c32f Show a selection in the focused main view
The focused main view could be scrolled but not pointed at: there was no
way to say "this line" or "these lines", which is what every line-level
interaction needs — editing a line, copying part of a diff, and, later,
staging. So a diff main view now always carries a selection while focused,
starting at the first change already on screen so that focusing doesn't
move the view.

The mode of the selection lives on the main context (a single line, a
range from a fixed anchor, or the change block around the cursor); the
selected line and the range anchor stay in the view itself, whose native
range select draws them, so there is no new highlight machinery. The modes
and their keys are the ones the staging view has, including that the arrow
keys step from block to block in hunk mode.

A pane holds something to select only when what it is showing is a diff
with changes in it, which the render works out once its content is final: a
placeholder message is not a diff, and neither is a diff with nothing in it
at all, such as a binary file's or an empty commit's. Whether a selection
is then drawn there follows from the context stack, as it does for every
other view.

A click in the focused main view now has a meaning again: it selects the
line it points at.

Stefan HallerandClaude Opus 5 1dbb7051d0 Ask diff renderers for OSC 1717 metadata
A renderer that speaks the protocol emits nothing unless it is asked to,
so that its output stays plain wherever it is used outside lazygit. The
variable names the versions we understand.

git is one of the renderers we ask. It has no pager to spawn, and so no
terminal to spawn one in, but it still renders the diff itself — for the
word-diff formats, whose markup nothing else could resolve — so the
request has to be made before we decide a pty isn't needed.

Tags can only be deleted one at a time. If many of them have piled up,
for example backup tags made before rewriting a branch, deleting them
takes a lot of keypresses.

Let the delete menu work on a range selection of tags. It deletes the

remote tags, and asks for a single remote for all of them. After
deleting local tags, collapse the range selection to its first line;
otherwise it would select the tags that moved up into the place of the

Stefan HallerandClaude Opus 5.5 26ad23a8d2 Offer to update the branches stacked below the current one when pulling
When somebody else rebases a stack and force-pushes it, pulling the
topmost branch leaves the branches below it diverged. They can be
updated with `f`, but pushing the stack offers to push the branches
below along with the current one, and pulling should be symmetric.

When pulling, find the branches stacked below the current one that can
be updated without losing anything. These are those that are behind
their upstream branches, and those that diverged from them only because
they were rewritten. If there are any, show a menu that lists them and
offers to update them in addition to pulling the current branch, or to
pull only the current branch. The current branch is pulled as before.

The decision is based on the last fetch, not on a new one, so that the
menu appears right away. If the remote has changed since then, a branch
might not be offered although it could be updated; it then shows as
diverged after the pull, and pulling again offers it. The update itself
fetches the upstream branches and checks them again, so it never loses
commits.

Branches that are checked out in another worktree are not offered,
since updating them would change the files there.

The branches below are updated before the current branch is pulled. If
one of them pointed into the commits that a rebasing pull rebases, the
pull would move it when rebase.updateRefs is set, and updating it
afterwards would fail. If updating them fails, the current branch isn't
pulled.

Stefan HallerandClaude Opus 5.5 0a99f65be3 Auto-forward branches that are checked out in other worktrees
If a main branch is checked out in another worktree, auto-forwarding
after a fetch skips it. People who keep the main branch checked out in
their main worktree, and work on feature branches in linked worktrees,
therefore never get it forwarded.

Fast-forward such a branch in the worktree it is checked out in, as `f`
does. Skip the worktree if it has changes to tracked files, since
nobody asked for its files to change. Also skip it if it is mid-rebase
or mid-bisect, because its HEAD is then detached from the branch. A
branch in the current worktree is never forwarded. This covers the case
of the current worktree being mid-rebase on a main branch, whose ref
would otherwise be forwarded under the rebase.

Auto-forwarding now writes the same reflog message as `f`
("lazygit: update to upstream branch").

Stefan HallerandClaude Opus 5.5 1b4fc02040 Keep fast-forwarding the other branches when one of them fails
If `f` is used on several branches that are checked out in other
worktrees, the first worktree in which the fast-forward fails stops the
whole operation. For example, an untracked file that the fast-forward
would overwrite leaves the branches after it untouched, even though
nothing is wrong with them.

Try all the branches, and report the errors of the failed ones
together. The checks that refuse to fast-forward any of the branches
still run before anything is moved.

The next commit uses forwardBranches for auto-forwarding branches in
other worktrees, where stopping at the first failure is worse. A
worktree that fails every time would prevent the ones after it from
ever being forwarded. For this, forwardBranches also takes the git
commands to use, since a background worker doesn't block switching
repos.

Stefan HallerandClaude Opus 5.5 ef00e18247 Refuse to fast-forward a branch being rebased or bisected in a worktree
The worktree loader associates a worktree that is mid-rebase or
mid-bisect with the branch involved, even though its HEAD is detached.
Fast-forwarding such a branch therefore ran the fast-forward in that
worktree. This moved the detached HEAD and put the upstream commits
into the rebase in progress, while the branch stayed where it was.

Remember in the worktree model when its branch comes from a rebase or
bisect, and refuse to fast-forward the branch in that case. Updating
only the ref is no option for a rebase; the rebase writes the branch
when it finishes.

Stefan HallerandClaude Opus 5.5 5990946a23 Add a test for fast-forwarding a branch being rebased in a worktree
If a branch is being rebased in a worktree, pressing `f` on it moves
the detached HEAD of that worktree instead of the branch. The upstream
commits end up in the rebase in progress, and the branch itself stays
where it was. The same happens for a branch being bisected.

Stefan HallerandClaude Opus 5 83bff569a0 Allow fast-forwarding a range of branches
After somebody else rebased and force-pushed a stack of branches, every
branch of the stack has to be brought back to its upstream, and pressing
`f` on them one by one is as tedious as the checking out and pulling it
replaces.

Let `f` work on a range selection. The upstream branches are fetched with
one `git fetch` per remote, and the branches that aren't checked out
anywhere move in a single `git update-ref` call. All the selected
branches are looked at before any of them is moved, so a branch that has
to be refused leaves the others alone rather than updating the stack
halfway.

Stefan HallerandClaude Opus 5 78dc65cbeb Fast-forward branches whose upstream branch was rewritten
When somebody else rebases a branch and force-pushes it, the local
branch is left diverged from it, so `f` refuses to touch it. To get back
in sync, the branch has to be checked out and pulled, and for a stack of
branches that means doing it once per branch.

Such a branch has none of its own work in it, though: the commits it is
ahead by are the old versions of the ones that are now on the remote
branch. So when the branch has diverged and none of the commits it is
ahead by is ours, reset it to its upstream instead of refusing. This is
the same state that checking the branch out and pulling it would produce,
as rebase drops commits that the upstream already has.

A branch that isn't checked out anywhere is reset with the same
`git update-ref` that a fast-forward uses. One that is checked out
somewhere is reset with `git reset --keep`, and only when that worktree
has no changes to tracked files, so that the files under the user's feet
change no more than they have to. `--keep` also refuses to overwrite an
untracked file that the reset would bring in, which `--hard` would do
silently.

Stefan HallerandClaude Opus 5 667df9e784 Split fast-forwarding a branch into fetching and updating it
Fast-forwarding a branch that isn't checked out ran a single
`git fetch <remote> refs/heads/<branch>:<branch>`, so git's own refusal
to move a local branch backwards served as the safety check. A later
commit widens the set of branches the command accepts, and for that
lazygit has to make that decision itself.

Fetch the remote branch on its own, updating only its remote-tracking
branch. Then ask git whether the branch is an ancestor of it, and only
then move the branch: with `git update-ref` when it isn't checked out
anywhere, guarded by the hash we knew it to have, and with
`git merge --ff-only` in its worktree when it is checked out there.
Keeping `git pull --ff-only` for the latter case would fetch a second
time.

Fast-forwarding a branch that isn't checked out in a worktree had no
integration test at all, so add one. The second new test covers a repo
that keeps no reflogs, because a later commit starts reading those and
this case has to keep working without them.

Stefan HallerandClaude Fable 5.1 9a585bf11e Offer to push the branches stacked below the current one
After rebasing a stack of branches, every branch of the stack has to be
force-pushed, and so far the only way to do that in lazygit was to check
out each branch in turn and push it. For a stack of a dozen branches
that is a lot of work for a routine task.

When the current branch is pushed and there are branches below it in the
stack that have commits to push, show a menu that offers to push them
along with it. The menu lists the branches and how far each of them has
diverged from its remote branch, so that the user can see what is about
to happen. It doesn't show where each branch goes; the branches panel
doesn't show that for a normal push either. Pushing only the current
branch is the second entry. If any of the branches has diverged from its
remote branch, a single confirmation covers force-pushing all of them.

A branch is offered if its tip is a commit of the current branch that
isn't merged yet, it has an upstream that is stored locally, that
upstream is not gone, and it is ahead of its push destination. Branches
without an upstream are left out because a branch that was never pushed
can't be told apart from one that is meant to stay local. A branch that
is only behind is left out because pushing it would move the remote
branch back to an older commit; the lease doesn't catch that when the
remote-tracking branch is up to date.

Each branch is pushed to where `git push` would push it if it were
checked out, using the destination git reports in the %(push) field.
This honors push.default, remote.pushDefault and
branch.<name>.pushRemote without lazygit having to interpret them.
Branches going to the same remote are pushed in one command, with
--force-with-lease when the user confirmed force-pushing; the lease
checks each ref against its remote-tracking branch, so a coworker's
unseen push is still rejected. The current branch joins that command
when its remote-tracking branch is stored locally. Otherwise it needs a
plain push first, for example with --set-upstream, and that option
would apply to every refspec of a combined command; so in that case it
is pushed on its own as before, and the other branches follow in a
second command.

Pushing the current branch on its own still runs a bare `git push`, so
users who rely on push.default or remote.<name>.push for it see no
change. The push is non-atomic, as git defaults to; if one branch's
lease fails, the others still go through and the error names the one to
look at.

Stefan HallerandClaude Opus 5.5 51002cc473 Move gui.authorColors and gui.branchColorPatterns into gui.theme
We are about to add overrides of gui.theme for dark and light
backgrounds. Author and branch colors need them too, because a color
that reads well on a dark background may be hard to read on a light
one. Move them into gui.theme, so that the overrides cover them without
a mechanism of their own.

The migration of gui.branchColors creates gui.branchColorPatterns, so it
now has to run before the moves.

Stefan HallerandClaude Opus 5 087bdcd57f Render a diff without a pty on Windows
ConPTY doesn't carry a diff renderer's output to us as the renderer
wrote it. It parses the output into a screen buffer and re-encodes that
for the terminal side, and a sequence it can't represent there goes out
the moment it is parsed, separately from the text around it. The OSC
1717 records a renderer states its diff lines in therefore arrive
detached from the rows they describe, and the identity layer attributes
rows to the wrong diff line or to none.

Feed the renderer through a pipe there instead, so that its bytes reach
us unaltered. A stdin filter becomes a command of our own, since git
only invokes the one named by GIT_PAGER when it talks to a terminal; an
external diff renderer is git's own business either way and needs
nothing but the pipe.

Unix keeps the pty. A renderer reads the width to lay out to off it, so
taking it away would leave every configuration that doesn't name a
width rendering at whatever the renderer falls back to, and diff
renderers have worked on Unix far too long for that.
LAZYGIT_RENDER_WITHOUT_PTY asks for the piped path anyway, which is how
the integration tests cover it on a platform where they run at all.

Tell a command that renders into a view how wide that view is, through
COLUMNS. git reads it in preference to the size of the terminal it is
talking to, so the diffstat now fills the view whether or not the render
has a terminal to offer.

A diff renderer that can't ask a terminal gets the width from it too;
difftastic, diff-so-fancy and delta all support COLUMNS, so we can stop
running git in a PTY and these will still work.

Stefan HallerandClaude Opus 5 afb66f78a9 Sort remote branches with the same committer date in stack order
Force-pushing a stack of branches puts the same commits on the remote,
so the remote branches panel shows the same alphabetical order for a
stack that the local branches panel did. Sort them by ancestry too,
which needs the tip hash and committer date of each remote branch.

Stefan HallerandClaude Opus 5 effe661e09 Sort local branches with the same committer date in stack order
In date order, the branches panel lists a stack of branches
alphabetically rather than from the top of the stack down. Rebasing a
stack creates all of its commits within the same second, so all of its
branch tips end up carrying the same committer date, and git sorts refs
with equal committer dates by name.

Sort each group of branches that share a committer date by ancestry
instead, so that a branch comes before the branches it is based on.
Branches that are not descended from one another keep the alphabetical
order git gave them. Determining the ancestry takes one more
for-each-ref call, and it only runs when there is a group to sort.

Stefan HallerandClaude Opus 5 3868a9407b Ask git for the branch when the HEAD file doesn't hold it
Reading HEAD is worth keeping for the repos it can answer for, because
the menu opens on a keystroke and asking git costs a process per entry.
So go to git only for the placeholder, and for anything else the read
can't make sense of. That last part also gets the menu an answer for
layouts we don't know about yet, where it used to give up and say
"Branch unknown".

Git needs two commands to cover every repo. `git symbolic-ref` names the
branch even when it has no commit yet; `git rev-parse` resolves a
detached HEAD, and fails on a branch without a commit.

A repo that keeps its refs in a reftable shows ".invalid" in the branch
column. Git stores the real HEAD in a binary table there and leaves
"ref: refs/heads/.invalid" in the HEAD file, so that anything still

We read that file and take the placeholder for a branch name.

The menu shows "Branch unknown" for every submodule, whatever it has

naming the directory, and for a submodule git writes that name relative
to the submodule. We hand it to os.ReadFile unchanged, so it resolves
against lazygit's own working directory and the read fails. A worktree
created with --relative-paths (or with worktree.useRelativePaths set)
gets a relative name too, and fails the same way.

The path column is the last one, so nothing pushes it aside; instead it
runs off the right edge of the menu itself, and the reader has no way of
telling that there is more to it. Give it a maximum width as well, sized
so that the three columns and the spaces between them fill the menu at
its widest.

A path loses its middle rather than its end, because the directory that
immediately contains the repo says more about where it is than the root
of the tree does. The whole path, with the home directory still
abbreviated, joins the names in the tooltip when it doesn't fit.

Each column of a menu is padded to the width of its widest entry, so a

column 86 of 88.

Truncate both names to 30 characters, and put the ones that got
truncated into the item's tooltip, so that the full text is still on
screen for the selected entry. Filtering keeps matching the full names
and the full path, which the columns no longer show in their entirety.

Stefan Haller 8b049be31d Find the lazygit root directory by go.mod instead of .git
Running the tests in an exported source tarball fails with "must run in
lazy project folder or child folder". GetLazyRootDirectory searches the
working directory and its parents for a .git directory, and a tarball
doesn't have one. This has always affected the integration tests; since
34da956f5d a unit test calls the function too, so now even
`go test ./... -short` fails.

Search for the go.mod file that declares lazygit's module instead. It
ships in tarballs, and there is exactly one of it per source tree.

Put the function in our own pkg/utils rather than change lazycore's; the
criterion is specific to lazygit, and I don't feel like making a change
to lazycore.

Return an error rather than call log.Fatal, and report it from the two
callers that run under `go test`. In a test binary, log.Fatal exits
without attributing the failure to any test. That is the failure mode
34da956f5d set out to remove. The remaining callers are development
tools that have nothing useful to do without the root directory; they
keep exiting, now through MustFindLazygitRootDirectory.

Also stop the search at the root of the file system rather than at "/".
On Windows the old loop walks up to "C:\" and then spins there forever.
