A refresh left the focused main view alone while a search was on, so the
diff on screen stayed as it was however much the working tree had moved
on underneath it. The search could not cope with the content changing
under it, and leaving the content alone was the way around that.
It can cope now. The positions are worked out again from whatever the
view holds, and the status with them, so render it like any other.

Opening the search prompt reads the whole of the view's content, so that
the search counts every match in it. Rendering the content again reads
only as much as the scrollbar needs, so the matches below that point are
lost. The "x of y" drops to what the shortened content holds, and grows
again as the user scrolls far enough to load more.
Read to the end while a search is on, the way opening the prompt does.

A view drew a selection because something told it to, from four places on
three different schedules: a context being focused, a context losing focus,
a context being activated over another one, and a list being re-rendered.
Whether the flags ended up describing the state of the app depended on
which of those had run last, and the last one to run was often none of
them: a refresh only re-focuses the view that has the focus, so a list
whose contents changed underneath an unfocused panel kept whichever
highlight it happened to have.
Derive both flags instead, in one place, from the two things they mean: a
view shows a selection while its context is on the stack and has something
to select, and the context the user is in shows an active one where the
ones behind it show inactive ones. Nothing else needs to say anything about
highlighting, so nothing else can leave a view saying something untrue
about where the focus is.

The filter input is where the keyboard points for as long as such a menu
is open, so that the first printable key can go straight into it. The menu
still gets every key the input doesn't take, because the input view is
embedded in the menu view, and the two are drawn as one focused panel.
Which keys the input takes changes once there is a filter: until then
printable keys still drive the menu, so that the configured navigation
keys work as usual, and afterwards they are all filter text. A menu item's
own keys are never bound in such a menu, because typing one has to reach
the filter rather than execute the item.
Escape gives up the filter and leaves the menu open; the next one closes
it. The filter prompt behind '/' is gone from these menus: the row already
does that job, and a second filter would only be confusing.

This fixes two problems:
1. the list selection updated before the list content did, which caused
a bit of a wobble effect in the list
2. the main view would first update to a different commit's diff and
then back to the one that is being moved, resulting in a very ugly
flicker especially when moving the todo multiple times with auto repeat
Ever since scrolling the selection into view became opt-in, we have been
fixing the same class of regression by hand, five times so far: a
controller moves the selection somewhere new, doesn't say that it wants
the view to follow, and the selection ends up off screen. The decision
needs facts from two places — whether the selection went somewhere new is
known to the list, whether the scroll position is the caller's to manage
is known to the caller — and asking every caller for both is what keeps
going wrong. The callers that get it wrong are usually not even the ones
that moved the selection: they are pass-throughs like postRefreshUpdate,
which can't know what a refresh did to the selection.
So default to scrolling, and let the two callers that maintain the scroll
position themselves say so.
The one case where scrolling is always wrong is a refresh that no user
action is behind: a background poll, or a reload of state on window
focus, after a subprocess, or after a repo switch. Those must leave the
viewport wherever the user last scrolled it to — that is what made the
scrolling opt-in in the first place. Both are already marked in
RefreshOptions, so the refresh can decide it once, centrally, instead of
each caller judging it.
A user action that ends in a foreground refresh does now yank the view
back to the selection if the user had scrolled away from it. That's a
behaviour change, and there may be actions where it turns out to be
unwelcome; those we can fix individually, and it beats the ones that
don't scroll today.

Reading more lines into a lazy-loaded view (e.g. a diff being scrolled)
never changes the window layout, and after the first screenful it
doesn't even change the visible content - the new lines land below the
viewport, so the only thing that changes on screen is the scrollbar
thumb. Yet each read triggered a full render: a layout pass plus a
redraw of every view. On a slow terminal that full-screen repaint on
every read is a big part of why scrolling through a not-yet-fully-read
diff stutters.
Route the task's refresh through a content-only render instead. It
skips the layout pass and only redraws the views whose content changed,
leaving tcell's cell-level dirty tracking to emit just the cells that
actually differ (in the steady state, the scrollbar column).

I copied all files except dot files (.github and .gitignore), the _examples
folder, and go.mod/go.sum.
At some point we may want to copy the files back to the gocui repo when other
clients (e.g. lazydocker) want to use the newer versions of them.
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.
The logic in postRefreshUpdate would only rerender the main view if the context
being updated is the current view. This is not the case when a popup is showing;
but we still want to render the main view in that case, behind the popup. This
happens for example when we refresh the Files scope, we determine that all
conflicts have been resolved and show a popup asking to continue the merge or
rebase, but the postRefreshUpdate of the Files context only happens when the
popup is already showing, so we would still see the conflict markers behind the
popup, which is rather confusing.
Previously we would re-render the focused main view several times during a
refresh, once for every side panel. While this should usually not be noticeable
for users because we are careful to avoid flicker when refreshing the main view,
this would sometimes lead to the main view scrolling up to the top by itself;
see PR description for more details.
When rerendering a view at the end of a refresh, we call HandleFocus only if the
view has the focus. This is so that we rerender the main view for the new
selection.
What was missing here is to update the view selection from the list selection if
the view doesn't have the focus, so that the selection is painted properly.
Normally this is not relevant because you don't see the selection if another
side panel has the focus; however, you do see it as an inactive selection when
e.g. a popup is shown, in which case it does matter.
This will become more important when we introduce section headers for commits,
because in that case the view selection needs to change when the working copy
state changes from normal to rebasing or vice versa, even if the list selection
stays the same.
The changed test submodule/reset.go shows how this was wrong before: when
entering the submodule again after resetting, there is a refresh which keeps the
same branch selected as before (master); however, since the branches panel is
not focused, the view didn't notice and kept thinking that the detached head is
selected (which it isn't, you can tell by running the test in sandbox mode and
focusing the branches panel at the end: you'll see that master is selected). So
the change in this commit fixes that.
Apparently this was an attempt at working around go's lack of default arguments,
but it's very unidiomatic and a bit confusing. Make it a normal parameter
instead, so all clients have to pass it explicitly.
Original commit message of the gocui change:
This fixes View.Size, Width and Height to be the correct (outer) size of a view
including its frame, and InnerSize/InnerWidth/InnerHeight to be the usable
client area exluding the frame. Previously, Size was actually the InnerSize (and
a lot of client code used it as such, so these need to be changed to InnerSize).
InnerSize, on the other hand, was *one* less than Size (not two, as you would
have expected), and in many cases this was made up for at call sites by adding 1
(e.g. in calcRealScrollbarStartEnd, parseInput, and many other places in the
lazygit code).
There are still some weird things left that I didn't address here:
- a view's lower-right coordinates (x1/y1) are one less than you would expect.
For example, a view with a 2x2 client area like this:
╭──╮
│ab│
│cd│
╰──╯
in the top-left corner of the screen (x0 and y0 both zero) has x1/xy at 3, not
4 as would be more natural.
- a view without a frame has its coordinates extended by 1 on all sides; to
illustrate, the same 2x2 view as before but without a frame, sitting in the
top-left corder of the screen, has coordinates x0=-1, y0=-1, x1=2, y1=2. This
is highly confusing and unexpected.
I left these as they are because they would be even more of a breaking change,
and also because they don't have quite as much of an impact on general app code.
Make it recognize URLs wrapped in angle brackets, and followed by punktuation.
We don't need this for the status panel, but we will need it for confirmation
panels.
After #3283 we need to read more lines initially so that the scrollbar goes to
its minimal height of 1 for long diffs. Without this, it would start with a
height of 2 and then become smaller after you scroll down half the window
height.
Notably, the reflog view is taking ages here because it's got a
few thousand lines to write to the view.
In future we should only populate the view's viewport.
This begins a big refactor of moving more code out of the Gui struct into contexts, controllers, and helpers. We also move some code into structs in the
gui package purely for the sake of better encapsulation
We refresh the view after reading just enough to fill it, so that we see the
initial content as quickly as possible, but then we continue reading enough
lines so that we can tell how long the scrollbar needs to be, and then we
refresh again. This can result in slight flicker of the scrollbar when it is
first drawn with a bigger size and then jumps to a smaller size; however, that's
a good tradeoff for a solution that provides both good speed and accuracy.
