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 on an unselected row still
creates a range selection.
While dragging, a "drop here" indicator shows where the commits will be
inserted.
Moving commits with the mouse is useful for the case that you want to
move them a longer distance, because that's slow when doing it one by
one with the keyboard, and also you don't want to resolve conflicts at
every step. The standard workaround for that is to enter an interactive
rebase first and then continue it afterwards, but that's a bit
cumbersome; dragging solves that nicely.
Closes#5842.
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.
Like in the staging view, drag with the mouse in a list view to create a
non-sticky range selection (including auto-scrolling as the mouse
reaches the view edge).
Give the list views the same edge autoscroll during drag selection
that the staging view already has; the new mouse-release binding stops
the autoscroll when the drag ends.
Dragging with the left button held now extends the selection from the
pressed line, exactly like moving with shift+up/down does. We use the
non-sticky flavor so that the range collapses on the next plain cursor
movement, again matching the keyboard behavior.
The binding is only registered for contexts that support range selection
in the first place; dragging in other lists continues to do nothing.
The staging view (and custom patch building view) already has the
capability to create a range selection by dragging with the mouse;
however, a longer range couldn't be selected this way because the
dragging stopped at the view edge. Add auto-scrolling so that the view
scrolls as the mouse reaches the view edge; slowly on the innermost edge
row, faster on the outermost row and beyond. Scrolling starts after a
short delay so that a drag merely passing near the edge doesn't scroll.
When the pointer reaches the edge of the view during a drag (or leaves
the view entirely, which mouse capture makes possible), keep scrolling
and extending the selection: slowly on the innermost edge row, faster
on the outermost row, and very fast beyond. Scrolling starts after a
short delay so that a drag merely passing near the edge doesn't scroll.
When the view loses focus mid-drag (e.g. because a popup appeared),
cancel the autoscroll and the mouse capture.
Add press/move/release primitives next to the existing Click. The test
driver remembers the last reported position so a release doesn't have
to repeat the coordinates, and RepeatMouseMove lets a test verify that
a held-button motion event within the same cell has no effect.
Route all mouse events to the view that was under the pointer when the
left button was pressed, until the button is released. Previously each
event went to whatever view was under the pointer at the time, so a
drag that left the view's bounds started acting on neighboring views.
Since events can now carry positions outside the view, clamp the view
cursor to the view's bounds in that case (handlers still receive the
unclamped position), and require an actual click for tab activation so
that a captured drag crossing the tab row doesn't switch tabs.
Releasing a mouse button was delivered as a plain mouse-move (hover)
event: the release processing resets dragState to NOT_DRAGGING, after
which the event fell into the NOT_DRAGGING branch. Views therefore had
no way of telling that a drag gesture ended, which the upcoming
drag-based features (range selection, commit reordering) need.
Deliver the release as a real mouse event with the MouseRelease key
and normalize its modifiers to ModNone, so release bindings also match
modified drags. Make recordClickInfo ignore it: a release is the end of
a click, not a click of its own, and must not break double-click
detection.
Add a test pinning down that a press/release/press sequence at the
same position is detected as a double click. An upcoming commit starts
delivering the release as a real mouse event to the click-recording
code, which must not mistake it for a click of its own.
When the left button is pressed and the pointer then moves, the event
that made the MAYBE_DRAGGING -> DRAGGING transition fell through the
switch without being assigned a key or modifier, so the first cell of
every drag arrived at handlers as a MouseRelease event without the
motion modifier and was effectively lost. Give it the same
MouseLeft/ModMotion identity as all subsequent drag events.
Held-button motion events that stay within the pressed cell carry no
information at all; swallow them instead of letting them through as
further release-shaped events (which used to clobber the double-click
state when the pointer jittered within a cell between two clicks).
I'm not a skilled UI designer, so I suspect there may be even better
options, but it's definitely already better than the raw ASCII "---" we
had before.
Put the line only at the beginning because it looks bad if the line
after the label is misaligned when labels don't have the same width
(e.g. "Remote" vs. "Local" in the divergence view).
When selecting sibling directories sharing a common prefix, trying to
add them to a custom patch or discarding them from the commit would only
add one, not both. We had the same bug in the files panel and fixed it
in #3599, but forgot to make the equivalent change in the commit files
panel.
Fixes#5866.
The root item's path is ".", and the path of a file at top level is
"./file". When using GetPath, this gives us "." and "file",
respectively, and isDescendentOfSelectedCommitFileNodes would return
false for these.
Working with the internal paths (i.e. without stripping the leading
"./") fixes this.
There is no known breakage that is caused by this, that's why I'm not
adding an integration test that demonstrates a bug.
Equivalent to the change that was made to isDescendentOfSelectedNodes in
files_controller.go in 302b621b68.
It never changes inside this function, so there's no need to recompute
it with every loop iteration.
Equivalent to the change that was made to isDescendentOfSelectedNodes in
files_controller.go in d0c6e27fee.
When lazygit is running in a VS Code window that doesn't have the focus
(e.g. a split tab) and you click in the commits panel to focus it and
select a commit at the same time, it would briefly select the commit you
clicked but then flash back to the commit that was previously selected.
This PR fixes that so that the clicked commit stays selected.
This was only a problem with VS Code; in Zed's builtin terminal it
worked, apparently because it first dispatches the click and then the
focus-in event. Ghostty and iTerm2 were not affected because they don't
dispatch clicks in inactive windows or tabs at all.
Labelling as ignore-for-release because it fixes a regression that was
introduced since the last release.
This fixes the problem described in the previous commit; we no longer
capture the selection at the start of the refresh. There's no reason to
do that (we don't do it for branches either). It is enough to capture
the selection in the final bounce, before we assign the new model slice.
When clicking in the commits view of lazygit running in an unfocused VS
Code window, VS Code first sends us the focus-in event and then the
mouse-click. The focus-in refresh captures the selection when it starts,
then we handle the mouse click and you briefly see the clicked row
getting selected, but then the selection flashes back to the original
row as the refresh restores it when done.
CreatePseudoConsole and ResizePseudoConsole reject zero dimensions with
E_INVALIDARG, but we legitimately request them: the pty is sized after
the main view, and that view is zero-sized while hidden, e.g. in
full-screen mode with a side panel focused. Entering that mode while a
custom pager is configured therefore made StartPty fail (degrading to
unpaged output now that the fallback works), and resizing a live pty
from onResize would fail layout. The Unix pty accepts zero sizes, so
the clamp lives in the Windows implementation only.

CreatePseudoConsole rejects zero dimensions with E_INVALIDARG, so
starting a pty sized after a hidden (and thus zero-sized) view fails.

NewCmdTask feeds the reader returned by its start func into a
bufio.Scanner, and Scanner.Scan panics with a nil pointer dereference
when that reader is nil. Two start funcs could produce one:
- newPtyTask's fallback for a failed StartPty returned a literal nil
reader, alongside an ExecCmd that was never started, so the intended
"fall back to a plain cmd task" never worked. This crashed lazygit on
Windows when using a custom pager with the main view zero-sized, e.g.
after pressing + twice to enter full-screen mode with a side panel
focused: ConPTY rejects zero dimensions, making StartPty fail.
- startCmdWithPipe returned nil when the pipe couldn't be created,
which the Unix pty fallback path can trigger, since a failed pty
start can leave the tty assigned to the command's stdout.
Make startCmdWithPipe never return a nil reader: when the pipe can't be
created, don't start the command at all and return an empty reader so
the task shuts down cleanly with the error in the log. Then route
newPtyTask's fallback through it, so a StartPty failure degrades to
running the command without a pty: the pager is lost, but the command's
output still renders.

NewCmdTask feeds the reader returned by its start func straight into a
bufio.Scanner, whose Scan panics on a nil reader with a nil pointer
dereference. startCmdWithPipe returns exactly that when the pipe cannot
be created.
Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
The fallback path in newPtyTask (taken when StartPty fails) needs the
same start-the-command-with-a-pipe logic that newCmdTask uses, so pull
it out into a helper that both can share. No behavior change.

A refresh from the UI thread returns immediately and applies its model
and view updates as queued UI-thread callbacks. A key pressed before
those have run is handled against the stale, pre-refresh state. For most
keys that's harmless, but some handlers turn that state into git
commands: pressing space twice in quick succession in the staging panel
builds the second patch from the already-applied diff and fails with
'patch does not apply', because the refresh after the first press is
what moves the selection to the next stageable hunk.
Notably, this is not just a regression of the recent change that made
UI-thread refreshes non-blocking; the window was merely much narrower
before. A blocking refresh parked the UI thread while the scopes'
bounces were queued, and the event loop drains pending keyboard input
with priority over queued user events, so a key pressed during the
blocked window still beat the queued state updates. The guarantee that
the next keypress sees post-refresh state had already ended when the
scopes' state updates moved from worker-side mutex-guarded writes to
UI-thread bounces.
Fix it with the input-blocking mechanism we already use for commit
surgery, exposed as a new RefreshBlockingInput entry point: it begins
blocking events synchronously in the calling handler, and ends the block
from a callback that the finishing step queues behind the refresh's own
updates. Keys pressed while the refresh is in flight are buffered and
replayed, in order, against the fully refreshed state; since a replayed
key's handler re-enters this same path, a burst of keypresses applies
sequentially, each one seeing the previous one's refresh. Unlike the old
blocking refreshes, this doesn't freeze the UI thread: rendering,
spinners, resizing, and mouse scrolling keep working while input is
withheld.
Blocking input is opt-in per call site rather than the default for all
UI-thread refreshes, because most refreshes (the focus-in and startup
refreshes, say) don't produce state that the next keypress depends on,
and blocking on them would delay typing for no reason. It should also be
limited to quick, narrow-scoped refreshes: a full refresh, or any scope
that pulls in COMMITS, can take very long in large repos and should
usually not hold up input.
Use the new function for the staging panel's stage/discard/edit-hunk
refreshes, for moving rebase todos, and for stash operations.
Labelling as ignore-for-release because it fixes regressions introduced
after the last release.
On startup we don't want to block input during the initial refresh (it
should be possible to press, say, `4` to jump to the commits panel right
after startup without a delay), and we also want panels to show their
contents as soon as possible; it doesn't matter so much that it's not in
sync, we go from empty to populated here. However, when switching repos
it can be confusing that some panels that are slow to update still show
the old repo's data while others already show the new one's data, so
update the UI only when everything is ready, and also block input to
prevent accidentally trying to act on the old, stale data.
Popping or dropping a stash shifts the indices of the entries below it,
and renaming re-creates the stash at the top, shifting all the others.
The stash model is only rebuilt by the refresh, which finishes in the
background, so acting on the next entry in quick succession — pressing
the key, confirming the popup, and pressing again right away — reads the
stale pre-operation indices and targets the wrong stash. Note that the
confirmation popup is no protection here: the race starts when the
confirm handler runs, and the next keypress can easily beat the refresh.
Use RefreshBlockingInput so a quick follow-up keypress is buffered and
replayed once the refreshed stash list is in place.
