The focused main view's click/enter/e/G handlers all need the same thing: given
a rendered diff row, the patch-space line it corresponds to. Until now that came
solely from delta's lazygit-edit:// hyperlinks, which only carry a path and a
single line number — no side. That's lossy: for a deletion the number is the old
line, but the consumers fed it into new-file lookups, and two consecutive
deletions (which share a new-file line number) couldn't be told apart at all.
Replace GetFileAndLineForClickedDiffLine with GetDiffLineInfo, returning the
fuller (file, type, new-line, old-line) record from diff-line-metadata-notes.md.
This is mechanism #1: parse the decolorized view buffer — walk up to the file's
"diff --git" section, reuse patch.Parse on it (splitting multi-file commit diffs
on the "diff --git" boundaries), and read the type and line numbers off the patch
arithmetic. It serves the structure-preserving renderings — no pager, git diff
--color, and delta --color-only without line numbers — with no external
dependency.
To avoid trusting a mis-parse, the parser bails when a hunk's body no longer
matches its header (Patch.IsWellFormed). That's what happens when a pager keeps
the diff/hunk headers but restructures the body: delta's line-number gutters push
the +/- marker off the start of each line, so every body line reads as context.
Such renderings fall through to the next backend rather than yielding a confident
wrong answer. (diff-so-fancy goes further and rewrites the headers too, so it
fails even earlier, on the missing "diff --git".)
GetDiffLineInfo is a seam with swappable backends: the buffer parser first, then
the old hyperlink reader as a fallback for renderings the parser can't handle
(delta's default mode, or delta with line-number gutters). The future #2 OSC
per-cell metadata reader plugs in ahead of both, behind the same record shape.
Wire the consumers to the record per that doc's field mapping:
- dive into staging/patch building lands on the exact patch line, looking a
deletion up by its old-file line number (PatchLineForOldLineNumber) so the
two-deletions case resolves correctly;
- `e` edits at the new-file line;
- `G` anchors the PR link on the left (old) side for a deletion, the right (new)
side otherwise.
The hyperlink fallback can't convey the side, so it reports DiffLineOther, which
the consumers treat as a non-deletion — i.e. exactly today's behavior.

Diving into staging or patch building from a focused main view (by
double-clicking a line, or pressing enter on the selected line) always
landed on a single-line selection. Entering the same views through the
side panel honours the UseHunkModeInStagingView config and selects the
whole hunk by default. The two ways in should agree, so that diving in
from the main view feels like the established flow.
A non-negative line index in NewState was overloaded for two intents:
clicking directly on the patch explorer view (where a single-line range
is the start of a drag) and diving in from the main view (where we want
the default select mode). Distinguish them with SelectLineInDefaultMode
on OnFocusOpts: the main-view entry points set it; the click-to-drag
path does not.
In hunk mode the selection covers the block of changes around the
clicked line. A context line has no surrounding changes, so we snap to
the next change line (as toggling hunk mode does); the clicked context
line itself is then not part of the selection.
This is a separate commit only because the branch is a throwaway
prototype; in a real history it would be folded into the commit that
introduces the focused-main-view enter behavior rather than landing on
top of it.

EscapeFromPatchExplorer re-renders the side panel's content back into the main
view and wants to land at the scroll position and selection the user had before
diving into staging/patch building. The previous version set the origin on the
next UI tick, after the placeholder had already been painted at the wrong
position, so the restore was visible as a jump.
Instead, ask the re-render itself to restore the scroll (via
ScrollToOriginYForNextTask), so the saved position is applied in the first
paint that shows the real content. The selection still needs the diff loaded
down to the selected line, so restore it via ReadToEnd once the content is
fully read; the scroll is no longer touched there.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
When re-rendering content the user was already scrolled into, we want the
saved scroll position applied exactly when the real content first paints — not
before. Setting the origin up front instead paints it onto whatever placeholder
is currently in the view (e.g. the shorter buffer CopyContent left there),
which flickers: either a blank frame past the placeholder's end, or a jump to
the top when the task resets the origin at startup.
Add ViewBufferManager.ScrollToOriginYForNextTask: the next cmd/pty task then
(a) does not reset the view to the top at startup even though the command key
changed, so the placeholder stays put, (b) sizes its initial read to the saved
position so enough content is loaded to fill the view there, and (c) scrolls to
it as part of the first refresh, in the same paint that shows the real content.
This is the cmd/pty analogue of RenderStringWithScrollTask.
No caller sets it yet, so this is behaviour-preserving on its own.

refreshMainViews reset the scroll position of every other main view at the
very top, before moveMainContextPairToTop runs its CopyContent. CopyContent
copies the previously-shown view's content into the now-visible one to avoid a
blank frame during the async re-render — but because the reset ran first, it
had already zeroed the origin of that soon-to-be-copied source view. The
placeholder therefore always appeared scrolled to the top, jumping away from
wherever the screen actually was, on every cross-pair transition.
Move the reset to after the copy. The end state is unchanged (each other main
view still ends at origin 0, and the destination always re-renders), but the
brief placeholder now stays at the source view's real scroll position until
the real content paints.

The layout scrolls a view up if its origin is past the bottom of its
content, to avoid showing blank space (e.g. after a resize). But it measures
content height by the lines loaded so far, and command/pty tasks load
asynchronously. So when a view is re-rendered while scrolled down, the layout
would yank it to the top because only a fraction of the content has been read
yet, then leave it there once loading finished.
Track whether a command task is actively reading (set synchronously when the
task is created, so a layout pass in between sees it; cleared at EOF, but not
when stopped, since that means a newer task is taking over) and skip the
scroll-up clamp for such views. onEndOfInput already re-clamps once loading
completes.

Instead of a user config that always shows a selection on focus, the
focused main view starts without a selection (matching master). Pressing
<space> shows a selection in the middle of the view (no scrolling);
pressing <esc> hides it again before falling through to exiting the view.
This was already possible, but only when a file was selected, and it woudln't
always land on the right line when a pager was used. Now it's also possible to
do this for directories, and it jumps to the right line.
At the moment this is a hack that relies on delta's hyperlinks, so it only works
on lines that have hyperlinks (added and context).
The implementation is very hacky for other reasons too (e.g. the addition of the
weirdly named ClickedViewRealLineIdx to OnFocusOpts).
Git only writes the space after a marker when there is a label to write
after it, and the label can be empty: `git checkout -m` with the diff3
conflict style, for instance, has no name for the common ancestor, so it
writes a bare "|||||||" line.
Git doesn't always write conflict markers of seven characters: the
conflict-marker-size gitattribute overrides that per file, and it is set
for good reasons — for file types whose regular content tends to contain
marker-looking lines, such as documentation about merging, or test
scripts. We hard-code seven characters everywhere we look for markers,
so none of that works.
Prepare for honoring the attribute by threading the marker size through
everything that recognizes a marker, carried on the file model. Nothing
fills it in yet, so we still use git's default size of seven everywhere,
and matching is unchanged: a marker consists of exactly that many marker
characters, and all but the "=======" one are followed by a space and a
label.
Creating and applying a stash both touch every changed file, so in a
large repo they can take long enough to be noticeable — and running them
on the UI thread meant the confirmation popup stayed on screen, frozen,
for the whole operation. Run them on a worker instead, with a spinner,
and keep blocking input for their duration so that the type-ahead
guarantee the refresh used to provide still holds.
Dropping stays on the UI thread: it only rewrites the stash reflog, so
it's fast no matter how big the stashes are.

Collapsing the range before kicking off the refresh paints the new
selection against the list as it was before the drop, so for a frame the
entries that were just dropped are still on screen (and, with
gui.shrinkSidePanelsToContent, the panel is still at its old size).
Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
Pushing the files context right after kicking off the refresh moves the
focus (and, with gui.shrinkSidePanelsToContent, resizes the panels) a
frame before the refreshed stash and files lists arrive. Doing it from
Then puts it in the same frame as the data it belongs to.

Stashing and popping change both the stash list and the files list.
With each scope updating the UI as soon as its own refresh is done, the
two panels visibly change at different times; with
gui.shrinkSidePanelsToContent that also means their sizes change at
different times than their contents.

Entering a submodule clears GIT_DIR and GIT_WORK_TREE, as it must: they
say where the superproject is. But the stack we push the superproject
onto so that escape brings us back only held its path, and for a repo
opened with --git-dir/--work-tree the path leads nowhere — git can't
find a repo there. Escaping out of a submodule of a dotfile repo failed
with "not a git repository", or, if some unrelated repo happened to lie
above the work tree, quietly switched to that one instead.
Push the environment onto the stack along with the path, taken from the
repo paths rather than from the process env, so that it also covers a
repo we worked the location out for ourselves.

onNewRepo also runs when switching repos, and a failure there leaves us
in the repo we came from — with a nil GitCommand, which nothing else is
prepared for. Only assign once we have one.

The commit list a filtering mode change leaves behind has nothing to do
with the one that was showing, so the scroll position it inherits says
nothing about where the selection ended up, and the selection can land
anywhere off screen. PostRefreshUpdate only moves the cursor within the
existing scroll position, so ask for the scroll separately, the way the
commits refresh does when it moves the selection itself.
Exiting filtering mode looked like it worked, but only by accident: the
commits refresh recognizes the commit that was selected before it ran,
selects it again at its new index, and scrolls because the index moved.
That does nothing for the case where the commit is gone from the list, or
for entering filtering mode, where we select the first commit ourselves.
Entering or leaving filtering mode switched the screen mode and the
focused panel immediately, then reloaded the commit list in the
background. The result was an unfiltered list presented in the layout
that says "you are filtering", with nothing to say that anything was
still happening — and in a big repo that state can last seconds.
Before we stopped blocking the UI thread on refreshes, the reload
happened before any of it, so the two always agreed; the price was a
frozen UI for the duration.
Do neither: reload on a worker, so the UI stays live, and hold back
everything the user can see of the change until the new lists are ready,
so they still land together in one frame. A waiting status says what is
going on in the meantime, and blocking input means the keys pressed while
it runs arrive after the change rather than acting on a list that is
about to be replaced.
Setting a filter and clearing it are the same transition in opposite
directions: mutate the mode, bring the screen mode in line with it,
reload the views that depend on the filter, and put the selection
somewhere sensible in the reloaded commit list. They were implemented
twice, once in the filtering menu and once in ModeHelper, which is how
the two came to repaint the commit list in different ways.
Derive the screen mode and the panel switch from whether a filter is
active after the change, so both directions fall out of the same code,
and give ModeHelper the entry points for both. The filtering menu is
left with nothing but the menu.
Blocking keyboard input and hiding the working tree state mode are two
separate concerns; they were fused into one helper because every caller
so far wanted both. A caller that blocks input for something other than a
rebase would then hide the "Rebasing" indicator for the duration of its
operation, which has nothing to do with it.
Make it an explicit option instead, so blocking input on its own doesn't
imply anything about the modes on display.
The mode it suppresses is active for any working tree state, not just a
rebase: merging, cherry-picking and reverting show through the same
indicator. Name it after what it hides.
Whether a graph can be drawn was read from the filtering mode, while the
graph itself is drawn over the commit list in the model. Those two only
agree once the list has been reloaded for the new mode, and a filtering
mode change reloads the list in the background, so in between we can be
asked to draw a graph over a list the graph makes no sense for.
That is not just cosmetic. Commits in a filtered list are almost never
each other's parents, so no pipe ever terminates: the pipe set grows by
one per row and every continuing pipe rescans it, which is cubic in the
length of the list. Escaping out of filtering mode with a filtered list
of 13000 commits — as you get once the 300 commit limit has been lifted,
which happens for good as soon as the selection passes COMMIT_THRESHOLD
— wedges the UI thread for around twenty minutes.
Record whether the list was loaded with a filter, right where the list
itself is stored, and decide from that. The graph now also stays up while
the pre-change list is still on display, rather than vanishing a moment
before the list it belongs to.
The pty teardown in Close runs on a background goroutine that doesn't
get to finish when lazygit is quitting: the process exits milliseconds
after the view buffer managers are closed. The job objects still cover
the clients -- KILL_ON_JOB_CLOSE reaps them when the process's handles
are rundown at exit -- but nothing reaps the conhost, so on Windows
builds whose conhost fails to run down on its own, quitting leaks one
conhost per live pty.
This is not a rare timing window: a diff longer than what has been
read keeps its git process (and thus its pty and conhost) running for
the entire time it is displayed, so that scrolling can read more.
Quitting while looking at a long diff is therefore the common case,
and with an external differ configured it leaks a conhost on affected
builds on almost every quit.
Fix this by having the gui's shutdown path wait synchronously for the
in-flight teardowns after closing the view buffer managers. A quit
signal makes the teardowns skip the conhost rundown wait -- the
conhost serves nothing once its clients are dead, and the exit must
not stall for its sake -- so the wait normally completes in
milliseconds, keeping quit as fast as before; a 2-second cap protects
the exit path even if a teardown wedges.

The task stop path terminates the still-running command by pulling its
*os.Process out of the Cmd interface and applying one global strategy
(TerminateProcessGracefully) to it. That shape can't accommodate the
upcoming fix for orphaned process trees on Windows: there, stopping a
pty task requires terminating the entire process tree via a job object
whose handle lives with the pty, not with the process. And the two Cmd
implementations genuinely need different strategies anyway: a
process-group kill (the likely future fix for #5675 on Unix) is only
safe for pty children, which run as session leaders, while plain
commands share lazygit's own process group.
So let each Cmd implementation decide how to terminate itself, and drop
GetProcess, which had no other callers. No change in behavior.

At the end of a diff against the worktree, git re-reads and refreshes
the index and writes it back if it found stale stat information
(diff.autoRefreshIndex, on by default). It holds index.lock for the
whole refresh; GIT_OPTIONAL_LOCKS does not cover this lock, and the
window scales with the size of the repository (~150ms for a 6k-file
repository with a warm stat cache).
On Windows, a pty task that is stopped because the user moved on
terminates its git process at an arbitrary point: tearing down the
pseudoconsole delivers CTRL_CLOSE_EVENT, which git leaves to the
default handler, which simply calls ExitProcess. If that lands inside
the refresh, a stale index.lock is left behind and the next git
command chokes on it. This is the same problem that 98801da106 fixed
by no longer killing git processes; the ConPTY support added in 0.63
reintroduced it through the close event.
Disable the automatic refresh for pty-rendered commands. They can
afford it: the refresh only persists refreshed stat information, and
lazygit's foreground git status refreshes -- which never run in a pty
and are never killed -- already write that back on every user action
and on terminal focus-in. The cost is that while the on-disk stat
cache is stale, an external differ is invoked even for files whose
stat information changed but whose content didn't, showing them as
empty diffs; this heals with the next foreground refresh, which also
re-renders the view.
Unix keeps the refresh: a stopped pty child gets SIGTERM there, and
git's signal handlers remove its lock files, so the lock window is
harmless. The rawGit renderer keeps it too: its tasks don't run in a
pty and are never killed on Windows -- they either run to completion
or die on a broken pipe mid-output, before the refresh begins.

Having the cache in state.yml causes this file to be rewritten every
60s, which is annoying if you have a lazygit running in the background
somewhere without even realizing it, and it keeps overwriting the
foreground lazygit's newer command shell history and recent repos list
with its stale data. State.yml should only contain things that change in
response to user actions, not periodically.
In the branches list we show the checks icon (✓, ✗ etc) instead of the
gihub icon for branches that are open and have a state. It is a little
confusing, because the ✓ in front of the name means something very
different than the ✓ after it, but the checks status is just too useful
to see in the list.
In the main view we show it as a compact status before the PR title,
with a hyperlink that takes you directly to the checks tab in Github.
The branch controller should decide which pull request to show, not how its
header is styled and linked. Move the existing formatter and state badge next
to the branch presentation helpers so subsequent header changes stay in one
layer.
GitHub exposes a combined status for the head commit without requiring
individual check contexts. Include that rollup in the existing request
and startup cache so every consumer sees the same state without making a
second network request.
For a long time lazygit has used the term "custom pager" to refer to
what's really a "diff renderer". A pager is a program that allows you to
view output page by page (hence the name), e.g. less; lazygit's custom
diff renderers are not pagers. It used the term only because the feature
is implemented using git's GIT_PAGER env var, but that's an
implementation detail.
Rename the 'git.pagers' config to 'git.diffRenderers', and restructure
its elements while we're at it to make things clearer:
- Add a 'type' field to explicitly specify which type of diff renderer
it is (the two fundamentally different ones are 'stdinFilter' and
'extDiff').
- Add a third type, 'rawGit', which has an 'args' field that makes it
easy to use 'git --color-words' as a custom renderer
- Unify the old 'pager' and 'externalDiffCommand' fields to a single
'command' field for both types
Existing config files are migrated automatically.
We don't want callers to need any additional logic, so pass in the
translation set so that the function can decide what static text to
return. This allows us to get rid of the CurrentPagerUsesGitConfigDiff
method which is in the way for the refactoring we're about to do.
Moving commits runs a rebase, which can take a while. Instead of
letting the drop indicator vanish the moment the button is released,
keep it in place and turn it into a "moving commits here" spinner once
the move takes longer than a short grace period, so that quick moves
stay free of flicker. The indicator is cleared when the post-move
refresh lands.
While a commit drag is in progress, escape now aborts it: the drag
state and the drop indicator are discarded and the mouse capture is
released, so nothing happens when the button is eventually released.
Otherwise escape keeps its normal meaning.
Reuse the drag autoscroller for commit drags. Scrolling stops once the
insertion point reaches the end of the allowed range in the scroll
direction, so during a rebase the view doesn't keep scrolling once the
last insertion position among the todos has been reached.
Pressing the left button on the current selection now starts a drag
that moves the selected commits, both in the normal commits view and
for todos during an interactive rebase. A press anywhere else falls
through to the usual click handling, so dragging from an unselected
line still creates a range selection, and releasing without having
moved collapses the selection to the pressed commit like a plain click
would.
While dragging, the insertion point follows the pointer: rows below
the dragged block insert after the pointed-at commit, rows above it
insert before it, and during a rebase the destination is limited to
the contiguous block of movable todos around the selection. gocui
moves the view cursor along with the pointer, so each drag event moves
it back to keep the original selection highlighted.
The move happens on release. The model may have been refreshed during
the drag, so the dragged commits are located again by their identity
(hash, subject, todo action); if they no longer form a unique
contiguous block, the drop is ignored rather than guessing.
Render the insertion point of a commit drag as a non-model item in the
commits list. It must be inserted at the right position relative to
the section headers, because the list renderer assumes non-model items
are ordered by their model index.
Not used yet, we'll hook it up to the drag gesture in the next commit.
Let the todo-move primitives take a distance instead of hardcoding a
single row, by iterating the one-row move in memory. Dropping a commit
several rows away thus rewrites the todo file once and, outside of an
interactive rebase, runs a single rebase rather than one per row.
Merge the up/down variants of the move commands into one
direction-parameterized implementation. Dragging commits is about to
need moves over arbitrary distances, which we don't want to build twice.
