The 'arabicshape' feature of vim is a transformation of unicode text to
make arabic and some related scripts look better at display time. In
particular the content of a cell will be adjusted depending on the
(original) content of the cells just before and after it.
This is implemented by the arabic_shape() function in nvim. Before this
commit, shaping was invoked in four different contexts:
- when rendering buffer text in win_line()
- in line_putchar() for rendering virtual text
- as part of grid_line_puts, used by messages and statuslines and
similar
- as part of draw_cmdline() for drawing the cmdline
This replaces all these with a post-processing step in grid_put_linebuf(),
which has become the entry point for all text rendering after recent
refactors.
An aim of this is to make the handling of multibyte text yet simpler.
One of the main reasons multibyte chars needs to be "parsed" into
codepoint arrays of composing chars is so that these could be inspected
for the purpose of shaping. This can likely be vastly simplified in many
contexts where only the total length (in bytes) and width of composed
char is needed.
The terminal buffer closes automatically when using `:terminal` and the
command exits without an error. This messes up some tests that expect
the terminal buffer to still be open. We can force the buffer not to
close by passing an argument to `:terminal`. This can be anything, since
the shell-test stub simply prints whatever argument it's given.
Avoid consecutive RPC requests involving :startinsert or :stopinsert,
because consecutive RPC requests may be processed together, before the
:startinsert or :stopinsert takes effect.
Also change some feed_command() to command() to make tests faster.
Problem: Message is cleared when removing mode message (Gary Johnson).
Solution: Do not clear the command line after displaying a message.

`nvim_(get|set)_option_value` pick the current buffer / window by default for buffer-local/window-local (but not global-local) options. So specifying `buf = 0` or `win = 0` in opts is unnecessary for those options. This PR removes those to reduce code clutter.
Problem: When setting a shell size smaller than the containing
terminal window through `:winsize` or `:set lines/columns`
the screen is not properly cleared.
Solution: Clear the tui dimensions rather than the grid dimensions.
Problem:
has('gui_running') is still common in the wild and our answer has
changed over time, causing frustration.

Solution:
Use stdin_tty/stdout_tty to decide if a UI is (not) a GUI.

Don't bother to emit the unrecognised sequence in DECRQSS response as it provides an echo roundtrip possibility

erase_internal() should only set fg/bg colour, resetting other attributes (especially RV)

Added vterm_screen_set_default_colors(), which repaints the cells in the buffer(s)

Permit either colour argument to be NULL to vterm_state_set_default_colors()

Delete the mk_wcswidth functions as they're not used; guard the CJK-wide one with an ifdef as by default we don't use it
816. By Paul "LeoNerd" Evans on 2022-10-01
Make sure to supply empty (void) prototype to functions that take no arguments in bin/vterm-ctrl.c
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.
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())`.
Problem: Command overlaps with printed text in scrollback.
Solution: Clear until end-of-line and use correct message chunk.
