The previous two commits stop gocui from flushing while suspended, but
that guard cannot be fully airtight from gocui's side: it is a
check-then-act on the suspended flag, so a flush racing the suspend
itself (e.g. from a spinner goroutine) could still reach the screen
just as it disengages, and tcell's disengageFinish mutates the cell
buffer without holding the screen lock. Upstream now closes this at
the source (gdamore/tcell#1139): draw() returns immediately on a
disengaged screen, and the draw scan loop can no longer stall on the
width-0 cells that a released cell buffer reports (#5309).
The delta over the previously pinned snapshot is these two fixes, a
CSI R input decode fix, a wasm packaging chore, and dependency bumps.

tcell's filterEvents goroutine sends events into eventQ with a plain
blocking send, while Fini (via finish/finalize) closes eventQ after
closing the quit channel. The goroutine can have already committed to
the ev = <-inQ select arm when quit is closed, so its send into eventQ
races with the close; the race detector flags this (send and close on
the same channel are unsynchronized), and if the close wins, the send
panics with "send on closed channel".
This was caught by the integration tests under the race detector,
where every test drives a real tScreen over a MockTerm and tears it
down via Fini, but it equally affects real-terminal shutdown.
Upstream fixed it in 243630d2 ("Fix screen Init/Fini races") by
tracking the filter goroutine in a WaitGroup that finalize waits for
before closing eventQ, and guarding the send with a select on quit.
That commit is not in a tagged release yet (latest is v3.4.0), so pin
the pseudo-version; the delta over v3.4.0 is just this fix, a Windows
key-release fix, a cell-rendering perf tweak, and dependency bumps.

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.
This provides two fixes:
- proper handling of keypad keys on certain terminals (e.g. iTerm2)
- fix problems pasting certain emojis or east asian text on Windows Terminal
In Gui.onWorker we only make the minimum possible change to get things to
compile after the API-breaking change of the gocui update; we'll make this
cleaner later in this branch.
The previous scrollbars were too chunky and encroached too much on a view's content.
The new ones are slim and right-aligned so they encroach into dead space between views
which is much better
... and import stefanhaller's tcell fork for real rather than just replacing it
This solves the problem that people trying to
"go install github.com/jesseduffield/lazygit@latest" would get the error
go: github.com/jesseduffield/lazygit@latest (in github.com/jesseduffield/lazygit@v0.40.0):
The go.mod file for the module providing named packages contains one or
more replace directives. It must not contain directives that would cause
it to be interpreted differently than if it were the main module.
The proper fix will come out of this PR but it's not yet merged:
https://github.com/gdamore/tcell/pull/439/files
In the meantime I'm just going to directly edit this from my vendor
directory. If it ends up stretching a while I'll fork tcell properly
and use the fork.
