Sometimes it takes a while to get PRs accepted upstream, and this blocks our
progress. Since I'm pretty much the only one making changes there anyway, it
makes sense to point to my fork directly.
This lets us get rid of a few more calls to Error(), and it simplifies things
for clients of OnWorker: they can simply return an error from their callback
like we do everywhere else.
We upgraded our minimum Go version to 1.21 in commit
57ac9c2189. We can now replace our
`utils.Min` and `utils.Max` functions with the built-in `min` and `max`.

When exiting filtering mode, we currently keep the selection index the same in
the commits panel. This doesn't make sense at all, since the index in the
filtered view has no relation to the index in the unfiltered view.
I often use filtering mode (either by path or by author) to find a given commit
faster than I would otherwise be able to. When exiting filtering mode, it's
useful to keep the same commit selected, so that I can look at the surrounding
commits, see which branch it was a part of, etc. So reselect the commit again
after exiting filtering mode.
Sometimes this is not possible, most likely when the commit is so long ago that
it's outside of the initial 300 range. In that case, at least select the commit
again that was selected before I entered filtering; this is still better than
arbitrarily keeping the same selection index.
To support this, we turn the confirmation prompt of the "Create fixup commit"
command into a menu; creating a fixup commit is the first entry, so that
"shift-F, enter" behaves the same as before. But there are additional entries
for creating "amend!" commits, either with or without file changes. These make
it easy to reword commit messages of existing commits.
We pass all of them to a single editor command, hoping that the editor will be
able to handle multiple files (VS Code and vim do).
We ignore directories that happen to be in the selection range; this makes it
easier to edit multiple files in different folders in tree view. We show an
error if only directories are selected, though.
We've seen a lot of issues recently where people complain that lazygit doesn't
behave as documented, but that was only because they were running the latest
release but were looking at the documentation of master. Make the documentation
links in the status panel point to the release that they are using in the hope
that this will help a little bit with this problem.
Some operations don't support switching to the editor from the commit message
panel; an example is the commit message panel that appears when moving a custom
patch into a new commit. Disable the "open in editor" menu entry in this case,
instead of silently doing nothing.
By default we now search for substrings; you can search for multiple substrings
by separating them with spaces. Add a config option gui.filterMode that can be
set to 'fuzzy' to switch back to the previous behavior.
Lazygit has two ways to decide whether it needs to ask the user to force-push:
1. if it knows ahead of time that the push will fail because the branch has
diverged, by looking at the incoming/outgoing information that it shows as ↑3↓7.
2. by examining the error that comes back when the push has failed.
The second situation should happen only rarely, because lazygit fetches every
minute by default, so the ↑3↓7 information is usually up to date. It might not
be if the user turned off auto-fetch (or increased the auto-fetch interval).
However, in this case it's almost always harmful to prompt the user to
force-push, because we know that the reason for diverging is that something was
pushed to the remote, and we would wipe it out by force-pushing. In such a
situation, the more likely user action is to pull the remote changes and then
push normally again.
So just remove the second prompt, and replace it by a better error message when
we detect that updates were rejected remotely.
A little bit of history archeology reveals that the second prompt was added at a
time where we didn't have the first one yet, so at that time it made sense to
have it; but when the first prompt was added, we should have removed the second.
... and when recalling a commit message from an old commit by pressing up-arrow.
This is necessary because committing turns our soft line breaks into real ones,
but when rewording we want to turn them back into soft ones again, so that it's
possible to insert words at the beginning of a paragraph and have everything
rewrap nicely.
This is only a best effort; the algorithm only removes those hard line breaks
that can be removed without changing the way the message looks. This works well
when the previous commit message was wrapped at the same width, which for most
users should be the most common case; but if it wasn't, the result is not great.
Specifically, if the old wrap width was smaller, some hard line breaks just
won't be removed; if it was wider though, you'll get an unpleasant comb effect
with alternating long and short lines. In such a case it's best to switch to the
editor and use whatever wrapping features you have there (e.g. alt-Q).
This should arguably have been done in b133318b40 already; it's becoming more
important now because we're going to extend the common code with more logic in
the next commit.
It starts a rebase on the bottom-most commit of the range, and sets all the
selected commits to "edit" (skipping merge commits, because they can't be
edited).
A common workflow for me is to create a fixup commit from only some of my
current changes; to do that, I enter a file, stage a few hunks, and then want to
invoke ctrl-f to find the base commit for these changes. Currently I need to esc
back to the files panel in order to do that; it's more convenient to be able to
do this right from the staging panel.
This commit introduces a new feature to the commit view, allowing users
to filter commits based on the author's name or email address. Similar
to the existing path filtering functionality, accessible through <c-s>,
this feature allows users to filter the commit history by the currently
selected commit's author if the commit view is focused, or by typing in
the author's name or email address.
This feature adds an entry to the filtering menu, to provide users with
a familiar and intuitive experience
Calling "git reset" on the command line (without further arguments) defaults to
--mixed, which is reason enough to make it the default for us, too.
But I also find myself using --mixed more often than --soft. The main use case
for me is that I made a bunch of WIP commits, and want to turn them into real
commits when I'm done hacking. I select the last commit before the WIP commits
and reset to it, leaving all changes of all those commits in the working
directory. Since I want to start staging things from there, I prefer those
modifications to be unstaged at that point, which is what --mixed does.
This fixes two problems:
- each time the custom commands panel was opened, the history of commands would
be shown in reversed order compared to last time. (The reason is that
lo.Reverse modifies the slice in place rather than just returning a new,
reversed slice.)
- when executing a previous command again (either by typing it in again, or by
picking it from the history), it should move to the beginning of the history,
but didn't.
We fix this by storing the history in reversed order (as the user sees it in
the panel), this makes the logic simpler. We just have to prepend rather
than append newly added commands now.
While this is theoretically a breaking change, it's not worth bothering because
the order was wrong for existing users in 50% of the cases anyway.
Scenario:
- show the files of a commit, escape out of it again
- start an interactive rebase of a stack of branches, with the rebase.updateRefs
git config set to true
- select one of the update-ref todos
- trigger a refresh (either manually or by bringing lazygit's terminal window to
the front)
This results in an error message "fatal: ambiguous argument '': unknown revision
or path not in the working tree."
Fix this by putting another band-aid on the check for the commit files refresh.
This is the easiest way to fix the problem, but I don't think it's the best one.
We shouldn't be refreshing the commit files context at all if it isn't visible,
because it's pointless; there's no way to switch to it again except by calling
viewFiles again with a specific ref. But I'm too lazy too figure out how to do
that right now.
After discarding file changes from the commit, the was still referencing
these indexes as being part of the range select. The consequence was
needing to hit escape twice to exit commit files in some situations.
Canceling the range select after discarding changes fixes that.
The waiting status shouldn't happen until after the user has responded
to the popup.
Since we're not giving a standalone prompt about clearing the patch, all
of the business in `discard` doesn't need to be in a function any more
It can be tedious after each cherry-pick opearation to clear the
selection by pressing escape in order for lazygit to stop displaying
info about copied commits. Also, it seems to be a rare case to
cherry-pick commits to more than one destination.
The simplest solution to address this issue is to clear the selection
upon paste.
The only exception is a merge conflict. Initially, I wanted to clear
selected commits in this scenario too. During a discussion we found out
that it may be convenient to have the copied commits still around.
Aborting the rebase and pasting the commits in the middle of a branch
can be a valid use case.
To do that, change the "Apply fixup commits" command to show a menu with the two
choices "in current branch" and "above the selected commit"; we make "in current
branch" the default, as it's the more useful one most of the time, even though
it is a breaking change for those who are used to "shift-S enter" meaning
"squash above selected".
As part of making lazygit more discoverable, there are certain keys which you almost certainly
need to press when you're in a given mode e.g. 'v' to paste commits when cherry-picking. This
commit prominently shows these keybinding suggestions alongside the others in the option view.
I'm using the same colours for these keybindings as is associated with the mode elsewhere e.g.
yellow for rebasing and cyan for cherry-picking. The cherry-picking one is a bit weird because
we also use cyan text to show loaders and app status at the bottom left so it may be confusing,
but I haven't personally found it awkward from having tested it out myself.
Previously we would render these options whenever a new context was activated, but now that we
need to re-render options whenever a mode changes, I'm instead rendering them on each screen
re-render (i.e. in the layout function). Given how cheap it is to render this text, I think
it's fine performance-wise.
This adds a bunch of tooltips to keybindings and updates some keybinding descriptions (i.e. labels).
It's in preparation for displaying more keybindings on-screen (in the bottom right of the screen),
and so due in part to laziness it shortens some descriptions so that we don't need to manage both
a short and long description (for on-screen vs in-menu). Nonetheless I've added a ShortDescription
field for when we do want to have both a short and long description.
You'll notice that some keybindings I deemed unworthy of the options view have longer descriptions,
because I could get away with it.
This is useful if you want to move a range of commits, so you select them, and
then realize it's better to do it in an interactive rebase. Pressing 'i'
preserves the range now.
This helps work around bugs in editors that may get confused about relative
paths (like nvim-remote, see https://github.com/neovim/neovim/issues/18519), and
shouldn't have any negative effect on others.
As part of this, you must now press enter on a merge conflict file
to focus the merge view; you can no longer press space and if you do
it will raise an error.
I prefer this because I almost never use sticky range selections. Also, this
fixes the issue that just clicking a line in a diff (without dragging) already
creates a range selection. It still does, technically, but it's no longer a
problem because a non-sticky one-line range selection behaves the same as a
non-range selection.
Something dumb that we're currently doing is expecting list items
to define an ID method which returns a string. We use that when copying
items to clipboard with ctrl+o and when getting a ref name for diffing.
This commit gets us a little deeper into that hole by explicitly requiring
list items to implement that method so that we can easily use the new
helper functions in list_controller_trait.go.
In future we need to just remove the whole ID thing entirely but I'm too
lazy to do that right now.
This wasn't necessary before, because the only available branch sorting option
was by recency, so the sort order couldn't change except by checking out
branches. Now, you can sort by committer date, so the branch order can change by
fetching; in this case it's important to keep the same branch selected. One
important use case is to rebase the checked-out branch onto master; you select
master, press "f" to fetch it (this can now change its position in the list),
and then press "r" to rebase. To make this work smoothly it's important to keep
master selected after pressing "f".
We don't need it there so no need to enable it.
I'm leaving the disabled reason checks there, even though they're now redundant,
because they're only one-liners and they communicate intent.
We want to show an error when the user tries to invoke an action that expects only
a single item to be selected.
We're using the GetDisabledReason field to enforce this (as well as DisabledReason
on menu items).
I've created a ListControllerTrait to store some shared convenience functions for this.
This requires us to change the 'v' keybinding for paste to something else,
now that 'v' is used globally for toggling range select. So I'm using
'shift+v' and I'm likewise changing 'c' to 'shift+c' for copying, so
that they're consistent.
We will need to clearly communicate this change in keybindings.
The only time we should call SetSelectedLineIdx is when we are happy for a
select range to be retained which means things like moving the selected line
index to top top/bottom or up/down a page as the user navigates.
But in every other case we should now call SetSelection because that will
set the selected index and cancel the range which is almost always what we
want.
This is the highest priority of the escape actions because it's the thing you're
most likely to want to do upon hitting escape if you have a range selected.
Applying this to the staging/patch-building views is tricky: if we want this logic
for when a range of lines is selected, we'll also need to apply it when a hunk
is selected too. I still think it's worth it though: I've often accidentally
escaped from the staging view when trying to cancel a range selection.
We're not fully standardising here: different contexts can store their range state however
they like. What we are standardising on is that now the view is always responsible for
highlighting the selected lines, meaning the context/controller needs to tell the view
where the range start is.
Two convenient benefits from this change:
1) we no longer need bespoke code in integration tests for asserting on selected lines because
we can just ask the view
2) line selection in staging/patch-building/merge-conflicts views now look the same as in
list views i.e. the highlight applies to the whole line (including trailing space)
I also noticed a bug with merge conflicts not rendering the selection on focus though I suspect
it wasn't a bug with any real consequences when the view wasn't displaying the selection.
I'm going to scrap the selectedRangeBgColor config and just let it use the single line
background color. Hopefully nobody cares, but there's really no need for an extra config.
This adds range select ability in two ways:
1) Sticky: like what we already have with the staging view i.e. press v then use arrow keys
2) Non-sticky: where you just use shift+up/down to expand the range
The state machine works like this:
(no range, press 'v') -> sticky range
(no range, press arrow) -> no range
(no range, press shift+arrow) -> nonsticky range
(sticky range, press 'v') -> no range
(sticky range, press arrow) -> sticky range
(sticky range, press shift+arrow) -> nonsticky range
(nonsticky range, press 'v') -> no range
(nonsticky range, press arrow) -> no range
(nonsticky range, press shift+arrow) -> nonsticky range
Previously we included all navigation keybindings from all views in the keybindings menu, meaning
if you pressed enter on 'next page' in the commits view, you'd end up triggering the action
in the sub-commits view.
Because we obtain disabled reasons after every action, we need to keep the code for doing so
super fast. As such, we should not be hitting the filesystem to get rebase state, instead
we should just get the cached state.
I feel like we should actually be using the cached state everywhere like we do with all
our other models if only for the sake of consistency.
A common issue I have is that I want to move a commit from the top of my branch
all the way down to the first commit on the branch. To do that, I need to navigate
down to the first commit on my branch, press 'e' to start an interactive rebase,
then navigate back up to the top of the branch, then move my commit back down to
the base. This is annoying.
Similarly annoying is moving the commit one-by-one without explicitly starting
an interactive rebase, because then each individual step is its own rebase which
takes a while in aggregate.
This PR allows you to press 'i' from the commits view to start an interactive
rebase from an 'appropriate' base. By appropriate, we mean that we want to start
from the HEAD and stop when we reach the first merge commit or commit on the main
branch. This may end up including more commits than you need, but it doesn't make
a difference.
The algorithm works by blaming the deleted lines, so if a hunk contains only
added lines, we can only hope that it also belongs in the same commit. Warn the
user about this.
Note: the warning might be overly agressive, we'll have to see if this is
annoying. The reason is that it depends on the diff context size whether added
lines go into their own hunk or are grouped together with other added or deleted
lines into one hunk. However, our algorithm uses a diff context size of 0,
because that makes it easiest to parse the diff; this results in hunks having
only added lines more often than what the user sees. For example, moving a line
of code down by two lines will likely result in a single hunk for the user, but
in two hunks for our algorithm. On the other hand, being this strict makes the
warning consistent. We could consider using the user's diff context size in the
algorithm, but then it would depend on the current context size whether the
warning appears, which could be confusing. Plus, it would make the algorithm
quite a bit more complicated.
There are two possible fixes for this bug, and they differ in behavior when
rewording a commit. The one I chose here always splits at the first line feed,
which means that for an improperly formatted commit message such as this one:
This is a very long multi-line subject,
which you shouldn't really use in git.
And this is the body (we call it "description" in lazygit).
we split after the first line instead of after the first paragraph. This is
arguably not what the original author meant, but splitting after the first
paragraph doesn't really work well in lazygit, because we would try to put both
lines into the one-line subject field of the message panel, and you'd only see
the second and not even know that there are more.
The other potential fix would have been to join subject and description with two
line feeds instead of one in JoinCommitMessageAndDescription; this would have
fixed our bug in the same way, but would result in splitting the above message
after the second line instead of the first. I think that's worse, so I decided
for the first fix.
While we're at it, simplify the code a little bit; strings.Cut is documented to
return (s, "") when the separator is not found, so there's no need to do this on
our side.
We do have to trim spaces on the description now, to support the regular reword
case where subject and body are separated by a blank line.
Without this it's not reliably possible to ask whether a given view is visible
by asking
windowHelper.TopViewInWindow(context.GetWindowName()) == context.GetView()
because there could be transient, invisible contexts after it in the Z order.
I guess it's a bit of a coincidence that this has never been a problem so far.
The output of the GetWindowDimensions function is hard to understand just by looking at it,
so I've added a helper function in the tests to render the window layout as text, so that
in order to create a new test you just come up with some args and paste the output as the
expected output.
This has the same downsides that any snapshot-based testing has: it's more brittle than
targeted assertions. But it is much easier to make sense of these snapshots than it is
to make sense of more fine-grained assertions, and I like the fact that these tests can
serve as documentation.
We are also removing the single-character padding on the left/right edges of the bottom
line because it's unnecessary
Unfortunately we need to create views for each spacer: it's not enough to just
layout the existing views with padding inbetween because gocui only renders
views meaning if there is no view in a given position, that position will just
render whatever was there previously (at least that's what I recall from talking
this through with Stefan: I could be way off).

refreshWorktrees re-renders the branches view, because the branches view shows
worktrees against branches. This means that when both BRANCHES and WORKTREES are
requested to be refreshed, the branches view would be rendered twice in short
succession. This causes an ugly visual glitch when force-pushing a branch,
because when pushing is done, we would see the ↑4↓9 status come back from under
the Pushing status for a brief moment, to be replaced with a green checkmark a
moment later.
Fix this by including the worktree refresh in the branches refresh when both are
requested. This means that the two are no longer running in parallel for an
async refresh, but hopefully that's not so bad.
When pulling/pushing/fast-forwarding a branch, show this state in the branches
list for that branch for as long as the operation takes, to make it easier to
see when it's done (without having to stare at the status bar in the lower
left).
This will hopefully help with making these operations feel more predictable, now
that we no longer show a loader panel for them.
Very similar to WithWaitingStatus, except that the status is shown in a view
next to the affected item, rather than in the status bar.
Not used by anything yet; again, committing separately to get smaller commits.
This is not a complete fix, but it's good enough to fix the spurious test
failures of submodule/reset.go. We have some vague hope to fix this in a more
sustainable way by somehow improving our concurrency model fundamentally, but
that's a more long-term undertaking, and it's annoying that this test fails so
often, so let's fix it in this way for now.
A new gui config flag 'portraitMode':<string> is added to influence when
LazyGit stacks its UI components on top of one another.
The accepted values are 'auto', 'always', 'never'.
'auto': enter portrait mode when terminal becomes narrow enough
'always': always use portrait mode unconditional of the terminal
dimensions
'never': never use portraid mode

Previously there was no way to render a view's search status without also moving the cursor
to the current search match. This caused issues where we wanted to display the status
after leaving the view and coming back, or when beginning a new search from within the
view.
This commit separates the two use cases so we only move the cursor when we're actually
selecting the next search match
Now that we no longer show it in a loader panel, but in the app status view,
it's awkwardly long (the loading animation is much further to the right than for
other waiting status texts). Hopefully seeing just "Fast-forwarding <branch>" is
enough to be able to tell what's happening.
We do this for two reasons:
- when popping up a credentials prompt, it looks distracting if the waiting
status keeps spinning while the user is typing the password
- the task that updates the waiting status periodically would keep the program
busy, so integration tests would wait forever for the program to become idle
again
This can be useful when you know that a cherry-picked commit would conflict at
the tip of your branch, but doesn't at the beginning of the branch (or
somewhere in the middle). In that case you want to be able to edit the commit
before where you want to insert the cherry-picked commits, and then paste to
insert them into the todo list at that point.
This is useful to disable items that are not applicable right now because of
some condition (e.g. the "delete branch" menu item when the currently
checked-out branch is selected).
When a DisabledReason is set on a menu item, we
- show it in a tooltip (below the regular tooltip of the item, if it has one)
- strike through the item's key, if it has one
- show an error message with the DisabledReason if the user tries to invoke the
command
Add co-author to commits
Add addCoAuthor command for commits
- Implement the `addCoAuthor` command to add co-authors to commits.
- Utilize suggestions helpers to populate author names from the suggestions list.
- Added command to gui at `LocalCommitsController`.
This commit introduces the `addCoAuthor` command, which allows users to easily add co-authors to their commits. The co-author names are populated from the suggestions list, minimizing the chances of user input errors. The co-authors are added using the Co-authored-by metadata format recognized by GitHub and GitLab.
This should already have been done when adding the "View divergence from
upstream" command, but now we're going to add yet another item to the menu that
is unrelated to setting or unsetting the upstream.
This fixes two minor problems with the prompts:
1. When pressing shift-A in the local commits view, it would first prompt
whether to stage all files, and then it would prompt whether to amend the
commit at all. This doesn't make sense, it needs to be the other way round.
2. When pressing shift-A on the head commit in an interactive rebase, we would
ask whether they want to amend the last commit, like when pressing shift-A in
the files view. While this is technically correct, the fact that we're
amending the head commit in this case is just an implementation detail, and
from the user's point of view it's better to use the same prompt as we do for
any other commit.
To fix these, we remove the confirmation panel from AmendHelper.AmendHead() and
instead add it at the two call sites, so that we have more control over this.
This encapsulates the logic to make sure we have something to commit; which is
to
- auto-stage all files if no files are staged and the SkipNoStagedFilesWarning
config is on
- otherwise, prompt the user whether they want to stage all files
- error out if we don't have any files at all
Of these, the first one was only done when committing with the built-in commit
message panel; there's no reason why it shouldn't also be done when committing
with the editor, or when amending, and now it is.
It implemented this because it wants to do custom truncation of the ref name;
however, we can achieve the same thing by passing the truncated ref name to our
DynamicTitleBuilder, which was previously unused.
When editing a commit, the index of the current commit can change; for example,
when merge commits are involved, or when working with stacked branches where
"update-ref" commands may be added above the selected commit.
Reselect the current commit after pressing "e"; this requires doing the refresh
blocking on the main thread. (Another option that I considered was to use a
SYNC refresh, and then select the new line with an OnUIThread inside the Then
function. This also works, but results in a very visible lag.)
This is useful for when you begin to type the message in lazygit's commit panel,
and then realize that you'd rather use your editor's more powerful editing
capabilities. Pressing <c-o> will take you right there.
It determines the yellow/red status by getting the merge-base between the
current branch and its upstream; while we're rebasing, the current branch is
HEAD, so it tried to get the merge-base between HEAD and HEAD{u}, which doesn't
work. Fix this by passing the name of the checked-out branch separately.
This also fixes a bug where after the rebase each commit in the commits view had a tick against it because we hadn't
refreshed the view since the base commit was no longer marked
This was on oversight on my part: I assumed that the --work-tree arg was
always intended for use with linked worktrees which have a .git file
pointing back to the repo.
I'm honestly confused now: seems like there are three kinds of worktrees:
* the main worktree of a non-bare repo
* a linked worktree (with its own gitdir in the repo's worktrees/ dir)
* a random folder which you specify as a worktree with the --work-tree arg
I'm pretty sure the --work-tree arg is only intended to be used with this
third kind or workree
The proper fix is to actually have these two functions share code,
or for views to be able to manage their own heights based on their contents.
But I want to get this out for the sake of a Lazygit Anniversary release.
Now that we refresh upon focus, we can scrap this file watching code.
Stefan says few git UIs use file watching, and I understand why: the
reason this code was problematic in the first place is that watching
files is expensive and if you have too many open file handles that
can cause problems.
Importantly: this code that's being removed was _already_ dead.
I've been thinking about this for a while: I think it looks really cool if nuking your working tree
actually results in a nuke animation.
So I've added an opt-out config for it
This allows to do the equivalent of "git rebase --onto <target> <base>", by
first marking the <base> commit with the new command, and then selecting the
target branch and invoking the usual rebase command there.
We are in the outsideFilterModeBindings section here; all of these handlers are
wrapped in a OutsideFilterMode guard in a loop below. No need to add one
manually here.
It's tricky to get this right for reflog commits wrt what's the current branch
for each one; so just disable it entirely here, it's probably not something
anybody needs here.
We want to mark all local branch heads with a "*" in the local commits panel, to
make it easier to see how branches are stacked onto each other. In order to not
confuse users with "*" markers that they don't understand, do this only for the
case where users actually use stacked branches; those users are likely not going
to be confused by the display. This means we want to filter out a few branch
heads that shouldn't get the marker: the current branch, any main branch, and
any old branch that has been merged to master already.
We've been sometimes using lo and sometimes using my slices package, and we need to pick one
for consistency. Lo is more extensive and better maintained so we're going with that.
My slices package was a superset of go's own slices package so in some places I've just used
the official one (the methods were just wrappers anyway).
I've also moved the remaining methods into the utils package.
In the presentation layer, when showing branches, we'll show worktrees against branches if they're
associated. But there was a race condition: if the worktree model was refreshed after the branches model,
it wouldn't be used in the presentation layer when it came time to render the branches.
A better solution would be to have some way of signalling that a particular context needs to be refreshed
and after all the models are done being refreshed, we then refresh the contexts. This will prevent
double-renders
There are quite a few paths you might want to get e.g. the repo's path, the worktree's path,
the repo's git dir path, the worktree's git dir path. I want these all obtained once and
then used when needed rather than having to have IO whenever we need them. This is not so
much about reducing time spent on IO as it is about not having to care about errors every time
we want a path.
We now always re-use the state of the repo if we're returning to it, and we always reset the windows to their default tabs.
We reset to default tabs because it's easy to implement. If people want to:
* have tab states be retained when switching
* have tab states specific to the current repo retained when switching back
Then we'll need to revisit this
Older versions of git don't support the -z flag in `git worktree list`.
So we're using newlines.
Also, we're not raising an error upon error because that triggers another refresh,
which gets us into an infinite loop
