Jesse's comment from https://github.com/jesseduffield/lazygit/issues/4237:
We recently added a new option to check out a commit's branch from within the
commits, reflog, and sub-commits panels:
https://github.com/user-attachments/assets/0a5cf3f2-6803-4709-ae5a-e4addc061012
After using it for some time, I find it annoying that the default option has
changed. I rarely find myself wanting to check out a branch from the commits
panel, and it's rarer still to want to check out a branch from the reflog and
sub-commits panel. Although there may be use cases for this, it is jarring that
something you can always do (checkout the commit) is harder to do than something
that you can sometimes do (checkout the branch).
We've also had a user complain (see
https://github.com/jesseduffield/lazygit/pull/4117) about their muscle-memory
being broken by the recent change, and I have also fallen victim to this. I
don't think that the new branch checkout option is sufficiently useful to
dislodge the existing keybinding, so let's swap them.
When the user checks out a commit which has a local branch ref attached
to it, they can select between checking out the branch or checking out
the commit as detached head.
This might seem controversial; in many cases the client code gets longer,
because it needs an extra line for an explicit `return nil`. I still prefer
this, because it makes it clearer which calls can return errors.
The current behaviour when creating a new branch off of a remote branch
is to always track the branch it was created from.
For example, if a branch 'my_branch' is created off of the remote branch
'fix_crash_13', then 'my_branch' will be tracking the remote
'fix_crash_13' branch.
It is common practice to have both the local and remote branches named
the same when the local is tracking the remote one. Therefore, it is
reasonable to expect that 'my_branch' should not track the remote
'fix_crash_13' branch.
The new behaviour when creating a new branch off of a remote branch is
to track the branch it was created from only if the branch names match.
If the branch names DO NOT match then the newly created branch will not
track the remote branch it was created from.
For example, if a user creates a new branch 'fix_crash_13' off of the
remote branch 'fix_crash_13', then the local 'fix_crash_13' branch will
track the remote 'fix_crash_13' branch.
However, if the user creates a new branch called 'other_branch_name' off
of the remote branch 'fix_crash_13', then the local 'other_branch_name'
branch will NOT track the remote 'fix_crash_13' branch.
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 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".
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.
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.
Save has been deprecated for a while, push is the recommended way to save a
stash. Push has been available since 2.13, so we can use it without problems.
The global counter approach is easy to understand but it's brittle and depends on implicit behaviour that is not very discoverable.
With a global counter, if any goroutine accidentally decrements the counter twice, we'll think lazygit is idle when it's actually busy.
Likewise if a goroutine accidentally increments the counter twice we'll think lazygit is busy when it's actually idle.
With the new approach we have a map of tasks where each task can either be busy or not. We create a new task and add it to the map
when we spawn a worker goroutine (among other things) and we remove it once the task is done.
The task can also be paused and continued for situations where we switch back and forth between running a program and asking for user
input.
In order for this to work with `git push` (and other commands that require credentials) we need to obtain the task from gocui when
we create the worker goroutine, and then pass it along to the commands package to pause/continue the task as required. This is
MUCH more discoverable than the old approach which just decremented and incremented the global counter from within the commands package,
but it's at the cost of expanding some function signatures (arguably a good thing).
Likewise, whenever you want to call WithWaitingStatus or WithLoaderPanel the callback will now have access to the task for pausing/
continuing. We only need to actually make use of this functionality in a couple of places so it's a high price to pay, but I don't
know if I want to introduce a WithWaitingStatusTask and WithLoaderPanelTask function (open to suggestions).
We have not been good at consistent casing so far. Now we use 'Sentence case' everywhere. EVERYWHERE.
Also Removing 'Lc' prefix from i18n field names: the 'Lc' stood for lowercase but now that everything
is in 'Sentence case' there's no need for the distinction.
I've got a couple lower case things I've kept: namely, things that show up in parentheses.
