GetIsRefreshingFiles() is never called anywhere in the codebase, so the
flag serves no purpose. Remove it from Gui, StateAccessor, and
IStateAccessor, and drop the two SetIsRefreshingFiles calls in
refreshFilesAndSubmodules that maintained it.

Operations that show an inline status next to the item they operate on
("Pushing", "Fast-forwarding", "Fetching", …) would sometimes fail to
remove this inline status when done.
Fixes#5534.
Pushing a tag triggers no refresh, so it used to redraw the tags view
by hand to remove the "Pushing" inline status. WithInlineStatus now
always re-renders after clearing the operation, so this is redundant.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Operations that show an inline status ("Pushing", "Fast-forwarding",
"Fetching", …) removed it by relying on the async refresh they trigger
to redraw the view after the item operation had been cleared. That
ordering was never guaranteed: the item operation is cleared on the
worker once the operation's function returns, while the refresh redraws
the item from the UI thread whenever its (asynchronous) git work
happens to finish. If the refresh redrew before the clear, the status
was left on screen with no later redraw to remove it, so the branch (or
tag/remote) stayed stuck showing e.g. "Pushing" indefinitely even though
the operation had completed. This is timing-dependent, which is why it
surfaced as rare, hard-to-reproduce reports and as flaky CI failures.
Fix it by re-rendering in stop() right after clearing the operation,
and by making these refreshes synchronous rather than async. Because a
synchronous refresh has already updated the model and queued its own
redraw by the time stop() runs, and UI-thread callbacks run in order,
the redraw we queue here runs last and draws the up-to-date model with
the status removed. An async refresh couldn't give that guarantee: its
model update might not have landed yet, so the redraw could briefly
flash the pre-operation status.
Pull refreshes through the shared CheckMergeOrRebaseAndSelectHeadCommit,
so that helper becomes synchronous too; its only other caller,
RegularMerge, thereby also refreshes synchronously, which is fine: a
synchronous on-worker refresh is what we want anyway.

Some operations used to freeze lazygit while they ran, with no sign that
anything was happening — the UI would just lock up until they finished.
This affected:
- Merging a branch (including squash merges)
- Rebasing a branch interactively onto another ref
- Setting a commit to "edit"
- Resetting to a commit, branch, or tag
- Continuing, skipping, or aborting a merge or rebase
Many of these were usually fast under normal conditions (e.g. a hard
reset when the head doesn't change, or a "rebase --continue" when
there's only a handful of commits left), but in some cases they could
take long (e.g. a hard reset to some distant commit where lots of files
changed). Now each of these shows a spinner while it works and keeps the
UI responsive, matching how similar operations already behave.
Resetting to a commit/branch/tag from the reset menu ran inline on the UI
thread with no spinner; a hard reset to a distant commit can take a while
and blocks the UI meanwhile. Run it on a worker with a waiting status. The
undo/redo callers of ResetToRef already wrap it this way.

Setting a single commit to "edit" ran the interactive rebase inline on the
UI thread with no spinner, while its sibling startInteractiveRebaseWithEdit
(used when editing multiple commits or quick-starting a rebase) already runs
on a worker with a waiting status. Make the direct path match.

The interactive-rebase item in the rebase-onto-ref menu ran inline on the UI
thread with no spinner, unlike its two siblings in the same menu (simple
rebase and rebase onto base branch), which already run on a worker with a
waiting status. Make it consistent.

The regular and squash merges from the merge menu ran inline on the UI
thread, freezing it with no spinner while git worked. Run them on a worker
with a waiting status, like the rebase entry points already do.

Continuing, skipping, or aborting a merge/rebase from the options menu ran
the git command inline on the UI thread, freezing the UI with no spinner
while it worked (a continue can replay many commits). Run the
non-subprocess path on a worker with a waiting status instead, matching how
the other merge/rebase entry points already behave.
The auto-skip recursion in CheckMergeOrRebaseWithRefreshOptions must not
start its own worker: it already runs on the caller's thread (the worker of
the enclosing waiting status, or the UI thread for the synchronous callers).
Route it through genericMergeCommandImpl with the waiting status suppressed
so its behavior is unchanged.

When showing the files of a commit, we used to display renamed files as
a pair of added and deleted files, rather than a single `R` entry. This
is inconvenient when just browsing the commit's files because you can't
see if the rename also has modifications; but it becomes a real problem
when trying to work with the renamed file in a custom patch if it also
had modifications; there was no way to discard them, for example.
The Files panel already shows renamed files as `R` and allows you to
stage/unstage/discard hunks in them, so there's no reason why the patch
building panel shouldn't allow the same; and this PR adds this.
To drop just the modifications of a rename, add the individual hunks to
the custom patch (the side panel shows a `◐` icon); reverting the patch
then only drops the modifications but not the rename. To also drop the
rename, add the entire `R` file to the custom patch from the side panel
(it gets a `●` icon).
When loading the files of a commit we passed --no-renames, so a rename
showed up as a separate delete and add rather than a single R entry.
That made it impossible to work with a rename that also modifies the
file: the modifications were spread across a full deletion and a full
addition instead of appearing as the handful of lines that actually
changed. The staging view already shows renames and lets you stage
their hunks, so there was no good reason for the patch builder to
differ; the flag was only there because the commit-file parser couldn't
cope with the rename record format.
Switch the commit-file loader and the per-file diff to --find-renames,
teach the parser about the rename record (a status followed by two
paths), and carry the previous path through the patch builder so the
diff for a rename is loaded with both paths, which is what makes git
emit the rename in the first place.
A whole-file selection keeps the rename in the header, so the rename
moves or is discarded together with the file's contents. A partial
selection instead strips the rename metadata and points the header at
the new path, so applying the patch only changes the contents and
leaves the rename in place; the blob index line is kept so that a 3-way
apply can still fall back to a blob merge.
Discarding a renamed file from a commit now discards both the new and
the old path, so the new file is removed and the old one is restored.
Changing the rename similarity threshold refreshes the commit files
panel too, not just the files panel, so that a rename can turn into a
delete and add or back. It is disabled while building a patch, however,
because the patch builder caches each file's diff by path and would
desync if a rename changed into a delete and add underneath it.
Finally, copying a file's diff from the commit files panel now passes
both paths for a rename, so the copied diff shows the rename instead of
a new-file add.

In many cases some of the side panels show a lot of empty space; for
example the branches panel when there is only a `main` branch. This gets
worse when `expandFocusedSidePanel` is on (accordion mode), in which
case the almost-empty panel gets even bigger when focused and steals
valuable space from the other panels that do have something to show.
This PR adds a new `gui.shrinkSidePanelsToContent` option which causes
side panels to never show more than their content (plus one blank line,
so it's clear there's nothing more below). This means that panel heights
are now dynamic and may change as their content changes; for example,
when the working tree is clean the Files panel shows only two blank
lines, but as you start changing file, it gets taller to show them.
The option is off by default because it takes some getting used to. It
is also independent of the `expandFocusedSidePanel` option; that one
just makes the effect even more pronounced.
Accordion mode expands the focused side panel, but when that panel has
little content (an empty Files panel, a Branches panel with only master)
it just fills the extra height with blank space. The same waste happens
for any panel that gets more height than it has content to show.
When this option is enabled, each side panel is sized to its own content
(plus a blank line, so it's clear there's nothing more below) rather than
to an equal share of the height. The height a small panel gives up flows
to the panels that have more content than fits; those grow up to their
content and then scroll, weighted toward the focused panel in accordion
mode so the two features compose. Only when every panel fits with room to
spare is the leftover shared out equally, regardless of focus: enlarging
the focused panel there would reveal no more content and would only make
the panels jump around as the focus moves.
The option is independent of expandFocusedSidePanel and off by default.
The status panel, and the stash panel when unfocused, keep their fixed
one-line height as before.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The height thresholds that decide between the proportional layout and
the squashed layout (and, within the squashed layout, between 3-row and
1-row unfocused panels) were hard-coded constants tuned for the fixed
set of five side panels. Now that the panels are configurable, a layout
with fewer panels has less to fit, yet was still forced into the
squashed layout at the same height as five panels would be.
Scale the thresholds down in proportion to the panel count so a smaller
layout keeps using the proportional layout at smaller heights. Only ever
scale down: raising the thresholds for more panels would make them
squash sooner, which works against the reason someone adds panels in the
first place (they want to see them).

A handful of default keybindings differ by platform (e.g. word-wise
cursor movement in text inputs uses alt on macOS but ctrl elsewhere).
Lazygit chooses these based on the OS it runs on, but that's the wrong
signal when the OS isn't where the user is actually typing: someone
running lazygit in a Linux container that they access over ssh from a
Mac gets the Linux bindings, when they'd rather have the Mac ones.
Remapping each binding by hand via config is tedious, so add a single
LAZYGIT_KEYBINDING_PLATFORM override.

This PR improves three rough edges around deleting worktrees and the
branches checked out in them:
- **Deleting a branch that's checked out in another worktree now
actually deletes the branch.** The menu used to offer to remove or
detach the worktree but then stop there, leaving behind the very branch
you asked to delete. Both actions now delete the branch afterwards, and
the labels say so ("Remove worktree and delete branch" / "Detach
worktree and delete branch"). The old "Switch to worktree" entry is
dropped — it's not a useful option in the context of deleting a branch.
- **A branch's local branch, remote branch, and worktree can be deleted
in one step.** Picking "Delete local and remote branch" for a single
branch that's checked out in another worktree used to fail with a
confusing "select them one by one" error (which only makes sense for a
multi-selection). It now goes through the same worktree menu, with
labels that make clear the remote is deleted too.
- **Pressing `d` on a worktree can delete its branch.** The plain
confirmation becomes a menu: "Remove worktree", "Remove worktree and
delete branch", and "Remove worktree and delete local and remote
branch".
Throughout, the explicit menu choice acts as the confirmation, so the
separate "Are you sure you want to remove worktree?" prompt is gone; the
dirty-worktree force prompt and the not-fully-merged warning still show
up when relevant.
Closes#5205.
Pressing `d` on a worktree only ever removed the worktree, leaving its branch
behind even though deleting it too is often what you want. Turn the confirmation
into a menu: "Remove worktree", "Remove worktree and delete branch", and "Remove
worktree and delete local and remote branch". The branch-deleting items come
after the plain removal (they do more harm if picked by accident); both are
greyed out for a detached-HEAD worktree, and the local-and-remote one is also
greyed when the branch has no upstream. The plain menu pick is the confirmation,
so the standalone "remove worktree?" prompt is gone (and its now-dead
translation string with it); the dirty-worktree force prompt and the
unmerged-branch warning still appear when relevant.

Picking "Delete local and remote branch" for a single branch that's checked
out in another worktree used to fail with "Some of the selected branches are
checked out by other worktrees. Select them one by one to delete them." That
message only makes sense for a multi-selection; for a single branch there's no
reason we can't remove the worktree and delete both the local and remote branch
in one go. Route that case through the same worktree menu as the local-only
delete, with labels that spell out that the remote goes too. The multi-select
error stays for actual multi-selections.

When you delete a local branch that's checked out in another worktree, the
menu offered to remove or detach the worktree but then stopped there, leaving
the branch you asked to delete still around. Now both actions delete the branch
afterwards, and the labels say so ("Remove worktree and delete branch" /
"Detach worktree and delete branch") to avoid surprises.
Also drop the "Switch to worktree" item: switching abandons the delete the user
asked for, and it's already reachable by checking out the branch or via the
worktrees panel. And drop the now-redundant "remove worktree?" confirmation:
the explicit menu pick is the confirmation (the dirty-worktree force prompt and
the unmerged-branch warning still appear when relevant).

Split the actual worktree removal out of the confirmation in Remove into a
non-confirming helper, and give both Remove and Detach an optional `then`
continuation that runs after a successful removal in place of the default
refresh. Upcoming flows need to delete the worktree's branch once the worktree
is out of the way; threading a continuation through (rather than the caller
firing branch deletion independently) keeps it ordered after the git command
that actually frees the branch. No behavior change yet.

Pull the merged-check-and-force-warning step and the actual git deletion

Creating a worktree in lazygit used to be more awkward than it needed to
be:
- The first thing you were asked was whether you wanted a "normal" or
"detached" worktree — a distinction that's confusing to face up front,
and meaningless when you're creating a worktree from a commit, tag or
stash (both choices did the same thing there).
- You then had to type the new worktree's path by hand. That's easy to
get wrong (a mistyped `.worktrees`, for instance), it wasn't clear
whether you were meant to enter the parent folder or the full path, and
it was ambiguous what a relative path would resolve against — especially
when you were already inside another worktree.
- If you picked a branch that was already checked out in another
worktree, lazygit still asked you for a path and only told you it
wouldn't work afterwards.
- There was no quick way to create a new branch and a worktree for it
(sharing the same name) in one step.
This PR reworks the whole flow:
- **No more up-front mode menu.** Pressing `w` on a branch, commit, tag,
stash or remote branch opens a menu whose options are tailored to what
you selected, and each option spells out exactly what it will do — e.g.
"New worktree for 'main'", or "New detached worktree at 'v1.2.0'".
- **You never type a path from scratch.** Lazygit offers ready-made
locations — the folders your existing worktrees already live in, plus an
optional configured default — and shows each as a full path before
anything happens. The folder name is filled in for you from the branch
(or the name you choose). You can still pick "Other…" to type a custom
path.
- **Create a branch and its worktree in one step**, with a single name
used for both. Slashes are preserved, so `feature/foo` gives you a
`feature/foo` branch and a matching nested folder.
- **Branches already checked out elsewhere are caught up front:** the
relevant option is greyed out with an explanation of why, instead of
letting you do the work and then failing.
- **The worktrees panel's `n` is now a single branch picker.** Start
typing, or pick from the list: choosing an existing branch checks it out
in a new worktree, choosing a remote branch creates a local tracking
branch for it, and typing a new name creates a new branch off your
current one — each then simply asks where to put the worktree. Branches
that are already checked out are left out of the suggestions.
There's also a new `worktree.defaultPath` setting to tell lazygit where
to create worktrees by default — useful before you have any existing
worktrees for it to take its cue from. Starting that path with `~/` is
supported (your home dir); this is also supported in the "Other…" path
prompt mentioned above.
Fixes#3230Fixes#4708Fixes#5664
Lazygit runs git directly rather than through a shell, so a literal "~"
reaches `git worktree add` unexpanded and git creates a directory named
"~" instead of using the home directory.
Expand the tilde ourselves, both for paths typed into the "Other"
location prompt and for the worktree.defaultPath config value.

The command was renamed from "View worktree options" to "New worktree",
but its keybinding config key was still 'worktrees.viewWorktreeOptions'.
That name no longer matches the command, and the 'worktrees' section made
little sense: it held a single binding that isn't even used in the
worktrees panel (that panel uses universal.new), only in the branches,
remotes, tags, commits, and stash panels. Other keybinding sections are
named after the panel they're local to; this one wasn't local to any.
Move it to universal.newWorktree, which describes the action and drops the
spurious section, and migrate existing configs automatically.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
RenameYamlKey can only rename a key in place, under the same parent. To
migrate a keybinding from one section to another we need to relocate the
key to a different parent mapping, which is a move, not a rename.
MoveYamlKey creates intermediate maps at the destination as needed and
prunes any maps left empty behind the key, so a section that held only
the moved key doesn't linger as an empty mapping in the user's config.

The old 'n' flow opened a "normal vs detached" menu (the same meaningless
gate the 'w' flow used to have), then asked for a base ref, a path typed from
scratch, and a branch name in three separate prompts.
Replace it with a single picker prompt titled "New worktree for branch",
suggesting local branches not already checked out anywhere, plus remote
branches that don't yet have a local branch of the same name. The entered
value is classified on confirm: an existing local branch checks out into a
new worktree, a remote branch creates a new local tracking branch, and
anything else creates a new branch off the current ref. All three then feed
the same location menu the 'w' flow uses, so paths are chosen from candidates
rather than typed blind. Picking a remote or new branch needs no separate
name prompt — the picker value already is the name. Checked-out branches are
filtered from the suggestions, and a verbatim type-in of one is rejected with
an error.
createWorktree now takes the context to switch focus to once the worktree is
created, so 'n' lands back in the worktrees panel while 'w' still lands in
the branches panel.
This deletes the old NewWorktree / NewWorktreeCheckout core and the now-
orphaned i18n (CreateWorktreeFrom, CreateWorktreeFromDetached, NewWorktreeBase,
NewBranchNameLeaveBlank), completing the migration started for 'w'.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The old flow forced an up-front "normal vs detached" menu (meaningless for
commits, tags and stashes), then asked the user to type a worktree path from
scratch — easy to get wrong, and ambiguous about what relative paths resolve
against. It also offered the same two actions everywhere regardless of what
was selected.
Replace it with per-context "Worktree" menus whose items imply the intent
(new branch + worktree, worktree for an existing branch, detached worktree),
each feeding a shared name -> location -> create pipeline. The location menu
offers candidate parent directories as absolute paths instead of a blank
field, and "Worktree for a branch" is disabled (with a reason) when that
branch is already checked out somewhere, rather than failing after the fact.
Each ref/commit panel binds 'w' in its own controller and calls the matching
typed entry point on the worktree helper, so which menu opens is decided
statically by the call site rather than by dispatching on a ref's dynamic
type. The three commit panels share one menu through BasicCommitsController;
there is no longer a shared worktree-options controller.
The worktrees-panel 'n' flow and its old core (NewWorktree /
NewWorktreeCheckout) are left untouched here so nothing is written and then
rewritten; they migrate, and the dead i18n strings get removed, in a
follow-up commit.

This is the core of "never type a path from scratch": from the repo root,
the configured default path, and the parents of existing worktrees, derive
the ordered list of directories under which a new worktree could be placed.
Pure and unit-tested here; wired into the creation flow in a later commit.

The redesigned worktree-creation flow never asks the user to type a path
from scratch; instead it offers candidate parent directories. Until a repo

users seed that list with a configured default location.

Custom pagers were not available on Windows because the feature depends
on a working PTY implementation, and the PTY library we are using
doesn't have support for Windows (see
https://github.com/creack/pty/pull/155). This PR adds this support on
our side; the same PTY library is still used on Mac and Linux, but on
Windows we now have our own implementation using ConPTY.
This also enables prompting for SSH passphrases for users who don't have
an ssh-agent running, which previously also didn't work on Windows.
There's one limitation here: pressing `f` in the Files panel means
`fetch --all` by default (unless you turn that off using `git.fetchAll:
false`), in which case passphrase prompting still doesn't work; the
reason is that git spawns a bunch of child processes for each remote to
be fetched, and on Windows these don't inherit the PTY like they do on
Mac and Linux.
Fixes#1453Fixes#5525
ConPTY compresses runs of default-colored spaces into ECH + CUF
(\x1b[NX\x1b[NC) instead of emitting them literally. ECH is still a
no-op for us — our buffer is built sequentially and has nothing to
erase — but CUF has to materialize as N visible space cells so the
gap actually appears, otherwise content the child wrote with leading
indentation slides left against the preceding cell.
The view's cursorForward branch reuses the same machinery as tab
expansion: substitute the trigger byte for a space and let the
repeatCount path emit the cells under the parser-tracked SGR. The
existing notifyCellsWritten plumbing then advances screenCol over
the gap, keeping subsequent CUP targets aligned.

ConPTY compresses runs of default-colored spaces into ECH + CUF
(\x1b[NX\x1b[NC) rather than emitting them literally. Both currently
fall through the parser's swallow path, so the gap they describe
collapses entirely and content that the child wrote with leading
indentation ends up slid left against the previous cell.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
ConPTY presents its child's output as a screen buffer and uses CUP /
CUD / CNL / VPA to skip over blank rows rather than emitting LFs. The
previous behaviour swallowed all of those and the visible content
collapsed together. Now the escape parser tracks the screen-relative
cursor row, and any CSI that moves the cursor past the current row
emits a cursorDown instruction that the view turns into the matching
number of empty lines.
Column tracking is deliberately omitted: doing it correctly would mean
duplicating the view's grapheme-cluster width math in the parser, and
ConPTY in practice positions to column 1 after a CR-equivalent, which
the existing wx-reset path already handles. ConPTY-internal scrolling
needs no special handling either: it only emits cursor-positioning
escapes within the first, un-scrolled screenful — once its screen
scrolls it switches to plain linefeeds, which the view advances on
directly regardless of the tracked cursor.
Backward cursor moves are silently dropped — the view's buffer is
append-style and can't undo earlier writes. The exception is cursor-home
(CUP to row 1): ConPTY emits it at the start of every screen, so rather
than drop it we re-anchor the row tracking to the current write position.
Without that, a view not rewound in lockstep with ConPTY's screen (the
command log, which streams pty output without a rewind) accumulates
drift, and every later absolute CUP becomes a dropped backward move that
collapses the rows ConPTY positioned with.

ConPTY presents its child's stdout as a screen buffer and uses CUP
(`\x1b[<row>;<col>H`) to skip over blank rows rather than emitting LFs
for them. Our escape interpreter swallows CUP via the catch-all
"valid CSI final byte we don't implement" branch, so the blank rows
the child put between non-blank ones disappear and the surrounding
lines collapse together — which is what makes the delta-rendered diff
in the screenshot look like its blank lines and section breaks were
removed.

The per-platform getCmdHandlerPty split existed because the Unix side
had creack/pty and the Windows side had nothing — so it fell back to a
non-pty handler. Now that oscommands.StartPty provides a pty on both
platforms, the two files collapse into one cross-platform
implementation and the stub is gone.
cmdHandler grows a 'wait' field because the pty path on Windows spawns
via CreateProcess and never runs exec.Cmd.Start — so cmd.Wait wouldn't
work there. Non-pty handlers set wait = cmd.Wait; pty handlers set it
to the wait closure StartPty returns.

Replace the StartPty stub with a real ConPTY implementation:
CreatePipe + CreatePseudoConsole + PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE
+ CreateProcess. Pagers and external diff tools now get real terminal
behavior instead of being handed pipes.
One Windows-specific quirk worth flagging: ConPTY does not EOF the
output pipe when the child exits; conhost keeps it alive until
ClosePseudoConsole is called explicitly. A background waiter goroutine
calls ClosePseudoConsole as soon as proc.Wait returns, so callers see
EOF on outRead — restoring the Unix master-fd-EOFs-when-slave-closes
semantics they depend on.
The ErrPtyUnsupported sentinel and the no-pty fallback in newPtyTask
are gone now that both platforms have a real implementation.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Move the pty master behind a small interface (Read/Write/Close/Resize),
and push the actual startup into a platform-specific StartPty function
in pkg/commands/oscommands. The Unix implementation still uses
creack/pty; the Windows implementation is a stub that returns
ErrPtyUnsupported, at which point newPtyTask falls back to a plain cmd
task — matching the existing Windows behavior.
The primitive lives in oscommands rather than pkg/gui because the
cmd_obj_runner pty handler (also in oscommands) is going to consume it
too, and tasks → oscommands is the existing dependency direction.
Same observable behavior on every platform; this just carves out a seam
for a real ConPTY implementation on Windows.
Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
Windows ConPTY can't attach a child process to a pseudoconsole via
os/exec — Go's stdlib doesn't expose PROC_THREAD_ATTRIBUTE_PSEUDOCONSOLE
(golang/go#62708). The ConPTY path has to call CreateProcess directly,
so it can't hand an *exec.Cmd back to the task runner.
Widen NewCmdTask to accept a small Cmd interface satisfied by both
*exec.Cmd (via the ExecCmd adapter) and the Windows ConPTY command type
we're about to add. Change TerminateProcessGracefully to take
*os.Process, which both cmd shapes can provide.
Behavior is unchanged on every platform.

The env var was previously set only on Windows, where the no-op pty
stub was just running the command without a pty and needed to expose
the width to pager scripts another way. With ConPTY coming to Windows
the rationale disappears there, but the env var is documented in
docs/Custom_Pagers.md for pager scripts that can't query the terminal
width directly. Set it on every platform so those scripts remain
portable, regardless of whether a pty is in play.
