This is a regression introduced with #5135. I didn't notice it because I am
using `gui.scrollOffBehavior: jump`, in which case the problem wouldn't appear;
it only happened with `scrollOffBehavior: margin` (which is the default). In
that case, if you used the arrow keys (or j/k) to move the selection so that the
view would start to scroll, empty space would appear.
This brings in https://github.com/jesseduffield/gocui/pull/98 with the following
fix:
Fix rendering of CRLF sequence ('\r\n')
The FirstGraphemeCluster call returns this as a single character; we want to
treat it the same way as a single \n.
This would be a problem if e.g. a progress bar used \r repeatedly to paint over
the same line, and then printed a \n to move on to the next line; the last pair
of \r and \n was swallowed.
Another scenario where this was a problem was if you stream output of a command
to the log, and the command used \r\n as line feeds. This happens for example
for a background fetch that fails with an error; in that case we print the
combined output (stdout plus stderr) to the log after the command finished, and
for some reason it uses \r\n in that case (I can't actually explain why; when I
do `git fetch --all | xxd` I see only bare \n characters). All output would
appear on one line then.
Also, filter out escape sequences for character set designation; there's nothing
useful we can do with them. In practice, the only one that you are likely to see
is `ESC ( B`, which is sent as part of tput sgr0, which is sometimes used in
scripts to reset all graphics attributes to defaults.
I've optimised for muscle memory backwards compatibility here:
- Outside interactive rebase: press 'f' then instead of a confirmation
panel, a menu appears where you can choose to keep the selected commit's
message
- Inside interactive rebase: press 'f' then press 'c' to see the menu
for keeping the message, where if you press 'c' again it will retain the
current message. so 'fcc' is the chord to press.
We're also now showing the -C flag (which is what enables the behaviour)
against the todo.
I've picked the 'c' keybinding because 'C' was taken and it corresponds
to the flag. Previously that showed a warning about a change in
keybinding for cherry picking but it's been ages since we've made that
change so I'm happy to retire it.
Not used yet, we pass an empty string everywhere, to match the previous
behavior. Just extracting this into a separate commit to make the next one
smaller.

It's been ages since we changed the key, users should hopefully be used to it by
now, and we want to reuse the key for something else later in the branch.

On very large screens they would get ridiculously wide.
The limits we chose here are a little arbitrary:
- 80 for confirmations and prompts
- 90 for menus
- auto-wrap width plus 25 for the commit message editor (or 100 if auto-wrap is
off)
To reproduce: open the keybindings menu ('?'), press '>' to select the last
line, esc to close it, open it again. The view would appear still scrolled down,
so the selected first line was out of view. Even worse, if you open a different,
shorter menu (e.g. the "View upstream reset options..." menu in the Files
panel), you'd only see the Cancel item, the other ones were scrolled out of
view.
This is a regression introduced with efd4298b5e91 (#5134).
Since the reflog can get very long, this saves some memory but especially some
UI thread lag. In one of my repos I had over 11'000 reflog entries (I guess I
should prune them more regularly...), and rendering them took ~600ms; since this
happens on the UI thread, there was an annoying stall for half a second after
every background fetch, for example.
This fixes a bug in ListContextTrait.FocusLine whereby the view would go blank
when scrolling by page (using ',' or '.') in views that have
renderOnlyVisibleLines set to true but refreshViewportOnChange set to false.
Currently we don't have any such views; the only ones who use
renderOnlyVisibleLines are commits and subcommits, and they also use
refreshViewportOnChange. However, we are going to add one in the next commit,
and eventually it might be a good idea to convert all our list views to that by
default, and get rid of the renderOnlyVisibleLines flag.
Move SetContentLineCount into OverwriteLinesAndClearEverythingElse. Calling it
separately beforehand is not concurrency safe; we need both to happen
when the view's writeMutex is locked.
We have this logic to avoid constantly rerendering the main view when hitting
up-arrow when you are already at the top of the list. That's good, but we do
want to scroll the selection into view if it is outside and you hit up or down,
no matter if it changed.
It is possible to scroll the selection out of view using the mouse wheel; after
doing this, it would sometimes scroll into view by itself again, for example
when a background fetch occurred. In the files panel this would even happen
every 10s with every regular files refresh.
Fix this by adding a scrollIntoView parameter to HandleFocus, which is false by
default, and is only set to true from controllers that change the selection.
We want to do this whenever we switch branches; it wasn't done consistently
though. There are many different ways to switch branches, and only some of these
would reset the selection of all three panels (branches, commits, and reflog).
We move the selection down by the number of commits that were reverted (to keep
the same commits selected). However, this only happens after refreshing, which
has rendered the main view with the wrong commit, so we need to render it again
after moving the selection.
There are many other callers of MoveSelection in LocalCommitsController, but all
of them happen before the refresh. Revert is special because it needs to move
the selection after refreshing, e.g. when reverting the only commit of a branch.
Now that we can use 'k' as a menu item binding (this was fixed in #5131), use it
for the "keep" entry in the merge menu. I don't think this will be a problem for
people's muscle memory, given that this menu is not encountered every day; and
it's simply the better keybinding.
This reverts commit b32b55201e0b392c777846de75eae3a2183aada6.
This is not really super important because we are very unlikely to assign a key
such as esc or up/down to a menu item. However, users might do this in a custom
commands menu, and in that case it is important that the builtin keys still
work; or they might remap those builtin commands to other keys, in which case
they might conflict with single-letter keys in normal menus.
The confirmation used to make sense back when the Open MergeTool command was its
own top-level command; however, that command was changed in 703f053a7e to open a
menu instead, and Open MergeTool is now just a submenu entry in that menu, so it
no longer needs a confirmation.
Users have filed issues with crash reports that seem to indicate that the
FileTreeViewModel gets swapped out (by a refresh) while a call to itemsSelected
is in progress, iterating over the previous items. Guard against this by locking
the mutex that we already have for this for the duration of the call.
I don't have a good way of testing whether the fix helps, because the crashes
only occurred very infrequently. Let's just see if the crash reports stop coming
in after we ship this.
Note also that this is only the minimal fix for the crashes that were reported.
Theoretically, the same problem could happen for a key handler itself, but we
never saw reports about that, so we don't bother doing anything about that yet.
Note also that long-term I envision a different solution to this class of
problems (discussed in https://github.com/jesseduffield/lazygit/issues/2974),
that's why I want to avoid locking mutexes more than necessary now.
It is a bit generic, it seems that users sometimes set it for other reasons, and
then they are confused why they don't see anything. Use a more specific name
instead.
We move the code to push the branches context into CheckoutRef, this way it
works consistently no matter where we call it from. Previously, checking out
remote branches or tags would switch to the branches view, but checking out a
commit did not.
Note that it now also takes effect for undoing or redoing a checkout, which may
be a bit questionable; but I still think it makes sense for this, too.
This doesn't really solve a pressing problem, because I guess it's unlikely that
users add spaces at the beginning or end of what they type into a prompt; but it
could happen, and in this case we almost always want to strip it. Just adding
this here for completeness while I was working on this code.
The only exception is the input prompt of custom commands, because who knows
what users want to use that input for in their custom command.
