Problem: When unibi_format() modifies params and data->buf overflows,
unibi_format() is called again, causing the params to be
modified twice. This can happen for escapes sequences that
use the %i terminfo format specifier (e.g. cursor_address),
which makes unibi_format() increase the param by 1.
Solution: Make a copy of data->params before calling unibi_format().
Now that the TUI calls nvim_paste and nvim_input through RPC, the data
race is much more likely, as nvim_paste is deferred while nvim_input is
not. Add an expect_child_buf_lines() call to avoid the race.
Problem: `chansend()` on Windows sends lines in reverse order.
Cause: Using \n instead of \r\n for newlines on Windows.
Solution: on Windows, use CRLF newline characters.

Extend the capabilities of is_os to detect more platforms such as
freebsd and openbsd. Also remove `iswin()` helper function as it can be
replaced by `is_os("win")`.
This is essentially a convenience wrapper around the `pending()`
function, similar to `skip_fragile()` but more general-purpose.
Also remove `pending_win32` function as it can be replaced by
`skip(iswin())`.
dispatch.sr.ht is being deprecated, meaning that using sourcehut CI
won't be possible (see https://github.com/neovim/neovim/issues/19609).
Since Github Actions doesn't provide any BSD runners an external service
is required and Cirrus CI seems like a good replacement for sourcehut.
Initially experimented with using FreeBSD and OpenBSD virtual machines
in GitHub Actions, but Cirrus has been a much better fit with better
performance, logs and overall experience.
Failing tests are automatically skipped on FreeBSD regardless if it's on
CI or not. Ideally these tests should only be skipped in CI with the
help of `isCI` helper function. Unfortunately, the tests don't recognize
the environment variable CIRRUS_CI even if it's set manually. This
workaround is good enough for the time being, but we might want to only
skip tests when using the CI (or even better, fix the failing tests).

* fix(test): screen.lua nil index
When actual_rows and expected_rows are different avoid a nil index.
* fix(tui): resize at startup
The deleted code is not needed after 402b4e8.
It caused the condition to false positive when the function was called
more than once before startup (first normal mode). Being itself what
set the dimension and not the user, locking the size of the screen to
an incorrect size.
Make got_winch an int to mitigate: tui_grid_resize changing the size
of the host terminal between the signal handler and the call to
sigwinch_cb. Since the actual signal handler uv__signal_handle doesn't
directly call the callback, the event loop does.

Problem:
- Since c57f6b28d7#8519, sockets are created in ~/.local/… but XDG
spec says: "XDG_RUNTIME_DIR: Must be on the local filesystem", which
implies that XDG_STATE_DIR is potentially non-local.
- Not easy to inspect Nvim-created temp files (for debugging etc).
Solution:
- Store sockets in stdpath('run') ($XDG_RUNTIME_DIR).
- Establish "/tmp/nvim.user/" as the tempdir root shared by all Nvims.
- Make ok() actually useful.
- Introduce assert_nolog().

Rename:
- `underlineline` to `underdouble`
- `underdot` to `underdotted`
- `underdash` to `underdashed`
`underdouble` also now takes higher precedence than `undercurl`.
Problem:
- Unix sockets are created in random /tmp dirs.
- /tmp is messy, unclear when OSes actually clear it.
- The generated paths are very ugly. This adds friction to reasoning
about which paths belong to which Nvim instances.
- No way to provide a human-friendly way to identify Nvim instances in
logs or server addresses.
Solution:
- Store unix sockets in stdpath('state')
- Allow --listen "name" and serverstart("name") to given a name (which
is appended to a generated path).
TODO:
- is stdpath(state) the right place?

Allow extra trailing spaces when matching terminal lines.
This make Nvim recognize `ESC NUL` as <M-C-Space>, as many terminal
emulators (including libvterm) send <M-C-Space> as `ESC NUL`.
There is already another unambiguous way to encode a `ESC` key supported
by libtermkey: `ESC [ 2 7 u`, which is a `CSI u` sequence.
If one still wants to use `ESC NUL` as `ESC`, they can just map
<M-C-Space> to <Esc>.

Fixes#17624.
The Lua modules that make up vim.lua are embedded as raw source files into the
nvim binary. These sources are loaded by the Lua runtime on startuptime. We can
pre-compile these sources into Lua bytecode before embedding them into the
binary, which minimizes the size of the binary and improves startuptime.
refresh_scrollback assumes pending scrollback rows exist only if the
terminal window height decreased (or the screen was full).
However, after accumulating scrollback, it's possible in some cases for
the terminal height to increase before refresh_scrollback is called via
invalidation (especially when the terminal buffer isn't initially
displayed in a window before nvim_open_term), which may crash.
As we'll have enough room for some scrollback rows, just append them to
the top of the buffer until it fills the window, then continue with the
previous logic for any remaining scrollback rows if necessary.
Problem: Cannot distinguish Normal and Terminal-Normal mode.

When entering terminal mode, cursorlineopt is no longer entirely
disabled. Instead, it's set to `number`. Doing so ensures that users
using `set cursorline` combined with `set cursorlineopt=number` have
consistent highlighting of the line numbers, instead of this being
disabled when entering terminal mode.

Problem:
jobwait() returns early if the job was stopped, but the job might have
pending callbacks on its event queue which are required to complete its
teardown. State such as term->closed might not be updated yet (by the
pending callbacks), so codepaths such as :bdelete think the job is still
running.
Solution:
Always flush the job's event queue before returning from jobwait().

Offsets of window were not taken into account when sending mouse
coordinates to the terminal. Therefore, when nu or rnu is set, the mouse
coordinates sent to the terminal were not correct. Change it to send the
correct coordinates by subtract window offset from col.
This makes it possible to restore the working directory of :terminal
buffers when reading those buffers from a session file.

After PR #8226 an unmapped META key in insert mode behaves like
ESC-<key> (:help i_META).
The behaviour does not fully match, since if <Esc>-<key> is pressed
manually then since it were pressed manually `gotchars` would be called
on the second <key> after insert-mode had already been left.
This would mean that `may_sync_undo` (called from `gotchars`) would
call `u_sync(FALSE)` on the second key (since we would be in normal
mode).
This overall means that <Meta-[something]> behaves differently with
respect to undo than <Esc>[something] when the [something] makes a
change.
As an example, under `nvim -u NONE`:
ihello<M-.>u
leaves the buffer empty, while
ihello<Esc>.u
leaves the buffer with one instance of `hello`.
- Fix by calling u_sync() manually in the new clause under
`normalchar:` in `insert_handle_key`.
- Update test in tui_spec.lua that accidentally relied on the old behaviour.

It is perfectly fine and expected to detach from the screen just by
the UI disconnecting from nvim or exiting nvim. Just keep detach() in
screen_basic_spec, to get some coverage of the detach method itself.
This avoids hang on failure in many situations (though one could argue
that detach() should be "fast", or at least "as fast as resize",
which works in press-return already).
Never use detach() just to change the size of the screen, try_resize()
method exists for that specifically.
PR #8221 took a short-cut when implementing the tests: screen.lua would
translate the linegrid highlight ids back into the old per-cell
attribute description.
Apart from cleaning up technical debt, this enables to check both rgb
and cterm colors in the same expect(), which previously was needlessly
restricted to ext_hlstate tests only.

Before this, --embed UIs (without --headless) would not trigger UIEnter.
For TUI, maybe UIEnter isn't useful, but:
- It is less "surprising"/special.
- Makes documentation simpler.
- When TUI becomes a coprocess, it will happen anyway.
simplify handling of default colors
nvim is always true color internally, remove ui_rgb_attached() check.
Fix "runtime termguicolors" test. The test actually reflected broken behavior
in (parent) nvim: nvim_ui_set_option("rgb", true) was not respected by existing
:terminal instances, so all 16-palette colors became dark blue.
Forcing insert-mode after the first paste-chunk seems to work, as an
alternative to a9e2bae0eb (insert-before-cursor).
NB: Dot-repeat needs to match the original action. Since a9e2bae0eb
changed paste to insert-before-cursor, dot-repeat must also. But that
makes dot-repeat unpleasant/unusual.
Inserting "after" the cursor in Normal-mode, for big paste-streams, is
not reliable: sometimes the text "after" the cursor ends up in the
middle of the pasted text. Maybe the cursor position is not updated?
To avoid weird behavior, always paste "before". Maybe nvim_put() or
vim.paste() can be fixed more properly later.
Problem: If multiple paste "chunks" are streamed, chunks after the
first line are pasted into the buffer.
Solution: Check for cmdline-mode for all chunks in a paste-stream.
- Workaround #10966: 'paste' option is not always reset.
- In any case there's not much reason to wait until phase=3, because
pasting in cmdline-mode skips lines after the first line (thus the
`:set paste .. :set nopaste` dance happens only ~once).

Adapt some tests for OpenBSD:
- scrollback_spec:
- seq(1) is not available on OpenBSD: we'd use jot(1).
- Instead use a (hopefully) portable awk(1) snippet.
- channels_spec
- job_spec
- tui_spec
- All "chunks" in a paste-stream should form a single undo-block. Side
effect of 7a85792884 was to create an undo-block for each chunk.
- Also: remove old :redraw force logic, irrelevant after 7a85792884.
Otherwise cursor and redraw code for normal and insert mode will not run. The
"tickle" workaround was used for this instead, and can now be removed.
The builtin vim.lua got the name
[string "-- Nvim-Lua stdlib: thevimmodule (:help l..."]
in error messages. Fix it to something reasonable.
- Introduce TRY_WRAP() until we have an *architectural* solution.
- TODO: bfredl idea: prepare error-handling at "top level" (nv_event).
- nvim_paste(): Revert luaeval() hack (see parent commit).
- With TRY_WRAP() in nvim_put(), 'nomodifiable' error now correctly
"bubbles up".
- nvim_paste(): Marshal through luaeval() instead of nvim_execute_lua()
because the latter seems to hide some errors.
- Handle 'nomodifiable' in `nvim_put()` explicitly.
- Require explicit `false` from `vim.paste()` in order to "cancel",
otherwise assume true ("continue").
- Show error only once per "paste stream".
- Drain remaining chunks until phase=3.
- Lay groundwork for "cancel".
- Constrain semantics of "cancel" to mean "client must stop"; it is
unrelated to presence of error(s).

This happens because `curwin->w_cursor.col` is sometimes decremented at
the end of `do_put`... because the editor is in Normal-mode instead of
the expected Insert-mode.
Caused by "typeahead race" (#10826): there may be queued input in the
main thread not yet processed, thus the editor mode (`State` global)
will be "wrong" during paste. Example: input "i" followed immediately by
a paste sequence:
i<start-paste>...<stop-paste>
^
"i" does not get processed in time, so the editor is in
Normal-mode instead of Insert-mode while handling the paste.
Attempted workarounds:
- vim.api.nvim_feedkeys('','x',false) in vim._paste()
- exec_normal() in tinput_wait_enqueue()
- LOOP_PROCESS_EVENTS(&main_loop,…,0) in tinput_wait_enqueue()
ref #10826
Fixes strange behavior where sometimes the buffer contents of a series
of paste chunks (vim._paste) would be out-of-order.
Now the tui_spec.lua screen-tests are much more reliable. But they still
sometimes fail because of off-by-one cursor (caused by "typeahead race"
resulting in wrong mode; fixed later in this patch-series).
Also fix V576: use width specification

<Paste> is a 3-byte sequence and the beginning one or two bytes can appear at
the very end of the typeahead buffer. When this happens, we were exiting from
`vgetorpeek()` instead of reading more characters to see the complete sequence.
I think this should fix#7994 -- at least partially. Before this change, when I
paste exactly 64 characters into a freshly booted instance, I get what I pasted
plus the literal text "<Paste>" at the end. Nvim also stays in nopaste mode.
The attached test case fails in this manner without the code change.
Fix#7994
Problem: When we changed startup to wait for the TUI (like a remote UI),
we forgot to set os/input.c:global_fd. That used to be done by
input_start().
Solution: Initialize os/input.c:global_fd before initializing libtermkey
(termkey_new_abstract) so that tui_get_stty_erase() and
friends can inspect the correct fd.

The test.functional.helpers and test.unit.helpers modules now include
all of the public functions from test.helpers, so there is no need to
separately require('test.helpers').
Previously, ordinary redraws were missing from terminal mode. Instead,
there was an async callback that invoked update_screen() on terminal
data regardless of mode (as if :redraw! was invoked by a timer).
This created some issues:
- async changes to an unrelated ordinary buffer were not always redrawn in
terminal mode
- screen cursor position was not properly updated in terminal mode (partial
fix, will be properly fixed in a follow up PR)
- ad-hoc logic was needed for interaction with special states such as
inccommand or horizontal wildmenu.
Instead redraw terminal mode just like any other state. This disables forced
redraws in cmdline mode, which were inconisent which async changes to
normal buffers (which are not redrawn in cmdline mode).
Before now, Nvim always degrades UI capabilities to the lowest-common
denominator. For example, if any connected UI has `ext_messages=false`
then `ext_messages=true` requested by any other connected UI is ignored.
Now `nvim_ui_attach()` supports `override=true`, which flips the
behavior: if any UI requests an `ext_*` UI capability then the
capability is enabled (and the legacy behavior is disabled).
Legacy UIs will be broken while a `override=true` UI is connected, but
it's useful for debugging: you can type into the TUI and observe the UI
events from another connected (UI) client. And the legacy UI will
"recover" after the `override=true` UI disconnects.
Example using pynvim:
>>> n.ui_attach(2048, 2048, rgb=True, override=True, ext_multigrid=True, ext_messages=True, ext_popupmenu=True)
>>> while True: n.next_message();
Problem: Using `:stopinsert` while in normal mode in a terminal buffer
prevents neovim from entering insert mode.
Solution: Move `stop_insert_mode = false` from terminal_check to
terminal_enter to be consistent with edit.c, as suggested by bfredl in
#9889.
Closes https://github.com/neovim/neovim/issues/9889.
Problem: Calling :stopinsert from RPC while in terminal-mode does not
go back to normal-mode.
Solution: Implement a check() handler for state_enter(), adapted from
insert_check().

ignore potentially wrong 'background' before the terminal response is
handled.
If terminal response is received during startup, set 'background' from
a nested "one-shot" (once) VimEnter autocmd.
The previous not-so-clever "self-rescheduling" approach could cause
a long delay at startup (event-loop does not make forward progress).

Problem: Relative cursor position is not calculated correctly.
Solution: Always set topline, also when window is one line only.
(Robert Webb) Add more info to getwininfo() for testing.

- Like Vim, use set_option_value() followed by reset_option_was_set().
- Do not use set_string_default(), so the default is predictable.
This affects `:set bg&`.
- Wait until end-of-startup (VimEnter) to handle the response. The
response is racey anyways, so timing is irrelevant. This allows
OptionSet to be triggered, unlike during startup.
Makes the 'scrollback' option more consistent (same default for all buffers) and future-proof.
- Default to -1 for all buffers, but treat it as an implementation detail.
- Document range of 1 - 100_000.
- New terminal buffer by default sets scrollback=10_000 if the global default is -1.
- Existing terminal buffer: On entering terminal-mode or on refresh, if the user explicitly did `:set[local] scbk=-1`, the local value goes to 100_000 (max). (This is undocumented on purpose. Users should work with explicit values in the range of 1-100_000.)
- Avoid using platform-specific shell, it failed in MINGW_64 env.
- tty-test.c echos our input, which is exactly what we need for this test.
- Test fails correctly if 894f6bee54 is reverted.
wp->w_height_inner now contains the "inner" size, regardless if the
window has been drawn yet or not. It should be used instead of
wp->w_grid.Rows, for stuff that is not directly related to accessing
the allocated grid memory, such like cursor movement and terminal size
By historical accident, Nvim defaults to background=light. So on a dark
background, `:colorscheme default` looks completely wrong.
The "smart" logic that Vim uses is confusing for anyone who uses Vim on
multiple platforms, so rather than mimic that, pick the (hopefully) most
common default.
- Since Neovim is dark-powered, we assume most users have dark backgrounds.
- Most of the GUIs tend to have a dark background by default.

- window_split_tab_spec.lua: Put cursor at bottom of :terminal buffer so
that it follows output.
- inccommand_spec.lua: Increase timeout to allow 2nd retry.
- Timer tests are less reliable on Travis CI macOS 10.12/10.13.

Add ext_newgrid and ext_hlstate extensions. These use predefined
highlights and line-segment based updates, for efficiency and
simplicity.. The ext_hlstate extension in addition allows semantic
identification of builtin and syntax highlights.
Reimplement the old char-based updates in the remote UI layer, for
compatibility. For the moment, this is still the default. The bulitin
TUI uses the new line-based protocol.
cmdline uses curwin cursor position when ext_cmdline is active.
Show a proper confirmation dialog when trying to unload a terminal buffer while
the confirm option is set or when :confirm is used.

closes#7698
Wrapping a command in double-quotes allows cmd.exe to safely dequote the
entire command as if the user entered the entire command in an
interactive prompt. This reduces the need to escape nested and uneven
double quotes.
The `/s` flag of cmd.exe makes the behaviour more reliable:
:set shellcmdflag=/s\ /c
Before this patch, cmd.exe cannot use cygwin echo.exe (as opposed to
cmd.exe `echo` builtin) even if it is wrapped in double quotes.
Example:
:: internal echo
> cmd /s /c " echo foo\:bar" "
foo\:bar"
:: cygwin echo.exe
> cmd /s /c " "echo" foo\:bar" "
foo:bar
Make HlAttr contain highlighting state for both color modes (cterm and rgb).
This allows us to implement termguicolors completely in the TUI.
Simplify some logic duplicated between ui.c and screen.c. Also avoid
some superfluous highlighting reset events.
The old behavior is probably not justified, for the usual reason:
terminal buffers may have interactive processes, so cursor placement is
arbitrary, therefore tracking it in the jumplist is useless (or worse).
N.B.: per the docstring for `checkpcmark()` it looks like we were
calling `checkpcmark()` and `setpcmark()` in the wrong order.
