Subject: [PATCH 05/66] tui: Optimize cursor motions

Instead of emitting CUP in several places each with their own poor local
optimizations, funnel all cursor motion through a central place.

This central function performs the same optimization for every place that
needs to move the cursor, and implements a better set of optimizations:

* Emit CUU/CUD/CUF/CUB instad of CUP when they are likely shorter.
* Use BS and LF when they are shorter than CUB and CUD.
* Use CR for quick returns to column zero.
* If printing the next few characters is shorter than a rightwards motion,
  then just write out the characters.

Subject: [PATCH 06/66] tui: Use what scrolling PuTTY has.

PuTTY does not implement DECLRMM or DECSLRM, but it does implement DECSTBM.
So allow using PuTTY terminal scrolling when the scroll rectangle is the
full width of the terminal.

+Where possible, Nvim will use the terminal's ability to set a scroll region in

+description describes an ability to set top and bottom scroll margins, that is
+used.

+This will not speed up scrolling in a window that is not the full width of the

+
+This ability is only present in genuine Xterm, not in the many terminal
+emulators that incorrectly describe themselves as xterm.  Nvim's detection of

+colours when the COLORTERM or TERM environment variables contain the string
+"256" somewhere.

+Nvim supports using true (24-bit) colours in the terminal.  |terminfo| does
+not contain flags to say when terminals have true colour support.  So Nvim
+simply assumes true colour support for (all) "xterm", "rxvt", "linux",
+"putty", and "iterm" terminal types, or when Konsole or a terminal emulator
+that sets the COLORTERM environment variable to "truecolor" is detected.
+
+							*xterm-resize*
+Nvim can resize the terminal display on some terminals that implement an
+extension pioneered by the dtterm program.  |terminfo| does not have a flag
+for this extension.  So Nvim simply assumes that (all) "dtterm", "xterm",
+"teraterm", "rxvt" terminal types, and Konsole, are capable of this.
+
+					*cursor-shape* *termcap-cursor-shape*
+Nvim will adjust the shape of the cursor from a block to a line when in insert
+mode, on terminals that support it.  If Konsole is detected, it will use the
+idiosyncratic Konsole terminal control sequences for this, attempting to do
+the right thing if tmux is between Nvim and Konsole.  Otherwise, it uses the
+conventional DECSCUSR control sequences.
+
 							*cs7-problem*
 Note: If the terminal settings are changed after running Vim, you might have
 an illegal combination of settings.  This has been reported on Solaris 2.5

Subject: [PATCH 12/66] tui: Split fix_terminfo() up and refactor.

There are now a few built-in terminfo entries, taken either from unibilium
or ncurses terminfo, for falling back upon when there is no terminfo database
or when it is missing stuff.  In an ideal world, these would be in unibilium
itself.

The ultimate fallback, for no terminfo database and no built-in terminfo
record that matches the terminal type, is now the "ansi" terminal type; so
unknown terminal types are now considered to have at minimum the basic
ECMA-48 colour, motion, and editing capabilities.

The terminfo records are just blobs, raw images of the equivalent terminfo file
created with the od command.  No longer are incomplete terminfo records built
up with code.  These blobs are the full, real, records; already built.

The post-processing of the terminfo record, once found, is split into the
part where we fix known errors and deficiencies in terminfo, and the part
where we add extensions that we need that terminfo does not define
capabilities for.  In an ideal world, the former would be a no-op.

No part of the TUI layer apart from these is aware of terminal type or has
conditional code based upon checking environment variables at runtime.  It
is all pre-calculated and written into unibilium (or the TUIData object) at
initialization time.

This is fairly aggressive about turning on 256-colour and true colour support.

This also positively decodes genuine xterm for turning on DECSLRM use, rather
than assuming that anything that says that it is xterm is actually xterm,
fixing scrolling problems with vertically split windows.

Subject: [PATCH 13/66] tui: Disable interference in guicursor by higher
 layers.

Ironically, higher layers trying to be "smart" about the terminal type
but not actually being very smart at all, makes it more difficult rather
than less to correct the TUI layer.

Note that this orphans the os_term_is_nice() function and down the road,
presuming that we do not have to revert this, that function can be removed.
It incorporates knowledge of terminal types and behaviours in the wrong place.

Subject: [PATCH 14/66] tui: More refactoring, and improvements to cursor shape
 support.

The details are in the on-line help under :help cursor-shape .

The brief precis is that nvim is following the lead of tmux, and going
beyond what tmux does to make cursor shape changes work on a broad range of
terminals.  This includes on tmux itself, which is no longer bypassed.

+it.  It uses the same |terminfo| extensions that were pioneered by tmux for
+this: "Ss" and "Se".  If your terminfo definition specifies these, as some
+(such as "xterm+tmux") do, then nothing more is required.
+
+If your terminfo definition is missing them, then Nvim will on a wide range of
+terminals resort to using the conventional DECSUSR control sequence for
+adjusting the cursor shape.  If Konsole is detected, Nvim will use the
+idiosyncratic Konsole terminal control sequences for this.
+
+Note: tmux itself accepts the conventional DECSUSR control sequence, the same
+as many other terminals do.  It has to translate this into whatever control
+sequence is appropriate for the terminal that it is outputting to.  Like Nvim,
+it will use the "Ss" and "Se" capabilities from terminfo if they are present.
+
+Unlike Nvim, if they are not present in terminfo you will have to add them by
+setting the tmux "terminal-overrides" setting in $HOME/.tmux.conf .  It will
+appear that Nvim is not changing the cursor, but in fact it is tmux receiving
+instructions from Nvim to change the cursor and not knowing what to do.  See
+the tmux(1) manual page for the details of how and what to do in the tmux
+configuration file.  It will look something like: >
+		set -ga terminal-overrides '*:Ss=\E[%p1%d q:Se=\E[ q'

+	set -ga terminal-overrides \

Subject: [PATCH 20/66] tui: Improvements to RGB colour support. The details
 are in the on-line help under :help true-color .

The brief precis is that nvim is (I hope.) converging with tmux and libvte.
It is taking the same approach with setrgbf and setrgbb terminfo capabilities
that it does with the Ss and Se terminfo capabilities.

Subject: [PATCH 21/66] tui: Remove tmux wrapper from the Konsole path. tmux
 has its own code path, now; and the tmux wrapping was not the ideal thing to
 do in the first place.

Also improve the commentary on the built-in terminfo records.

Subject: [PATCH 28/66] tui: Fix Interix and account for deferred wrap. The
 Interix termcap entry is missing the carriage_return capability which nvim
 relies upon.  And Interix is one of the few terminal emulators that does not
 defer automatic wrap at the right margin, which is now accounted for when
 moving the cursor left and when outputting whole lines at a time.

Subject: [PATCH 32/66] tui: Treat genuine Xterm and iTerm.app as
 standards-conformant. They both can handle SGR control sequences in the form
 set out in ISO 8613-6:1994/ITU T.416:1993.

+ - The correct $TERM for GNOME Terminal has been "gnome" since 1999, or

+   "xterm-256color" are incorrect; for starters they do not include
+   iTerm.app's status line capability.
+ - The correct $TERM for Terminal.app is "nsterm".  "vt100", "xterm", and
+   "xterm-256color" are incorrect; for starters they do not include
+   Terminal.app's status line capability or correctly describe its

 If no built-in terminfo record matches the terminal type, the built-in "ansi"
 terminfo record is used as a final fallback.
 
+The built-in mini-database is not combined with an external terminfo database,
+nor can it be used in preference to one.  You can thus entirely override any
+omissions or out-of-date information in the built-in terminfo database by
+supplying an external one with entries for the terminal type.  Note that the

 example used &term which is no longer meaningful. Fortunately, we can change
 this into a useful example using $TERM that also shows how to address a
 common need with termguicolors at the same time.

that namespace, and the prefix is already used for some other TUI

Subject: [PATCH 49/66] tui: Do some deferred wrap on iTerm2.

Partly undo 8ab08a65ba3bc9a44741a2ec9aa81fbcc77467fb.  Further testing
by Enrico Ghirardi suggests limiting the non-deferred automatic wrap to
only the bottom line, whose rightmost column is not printed for iTerm.

Subject: [PATCH 55/66] tui: Do not optimize left motion at the right margin.

From observation, there are several different possible behaviours:

1. Deferred wrap like a real DEC VT.  The cursor stays visible in the last
   column, and CUB is calculated relative to that column.
   Examples: xterm, Unicode rxvt, PuTTY, nosh console-terminal-emulator,
   FreeBSD kernel's built-in emulator, Linux's built-in emulator
2. Deferred wrap like a real DEC VT.  CUB is calculated relative to the last
   column.  But the cursor is invisible.
   Examples: emulators using newer libvte
3. Non-deferred wrap.  The cursor has already wrapped to the next line and CUB
   does not wrap back.
   Examples: cygwin, Interix
4. Non-deferred wrap that acts like deferred wrap.  The cursor has already
   visibly wrapped to the next line, but CUB can wrap back around the left
   margin.
   Examples: Konsole
5. Deferred wrap with visibly out of bounds cursor.  The cursor visibly moves
   outwith the screen boundaries.  CUB is calculated relative to a cursor
   column that has overflowed the end of the screen grid array.
   Examples: iTerm2
6. Deferred wrap with invisibly out of bounds cursor.  CUB is calculated
   relative to a cursor column that has overflowed the end of the screen grid
   array.  And the cursor is invisible.
   Examples: emulators using older libvte

In many cases, nvim does not have enough information to know which behaviour
the terminal will exhibit, and thus the correct amount of CUB to issue.

Subject: [PATCH 58/66] tui: Recognize "Tc" terminfo capability.

This is a new convention pioneered by tmux.  It does not do much for
nvim; since nvim always looks to see whether it should be making up
"setrgbf" and "setrgbb" capabilities.  But it is a way for terminfo to
force this, irrespective of the hardwired list in the code, for more
terminal types.  On the gripping hand, updating terminfo descriptions to
actually have "setrgbf" and "setrgbb" capabilities so that nvim never
has to try to invent them in the first place, is as good if not better
an approach for overriding what is baked into the code.

 correct terminal type in your $TERM environment variable so that Nvim is
 pulling the correct entry from the terminfo database in the first place.
 
-As noted in the commentary in the terminfo source file:
- - The correct $TERM for GNOME Terminal has been "gnome" since 1999, or
-   "gnome-256color" since 2006.  "vte" and "vte-256color" are equivalents.
-   "xterm" and "xterm-256color" are incorrect.
- - The correct $TERM for iTerm.app is "iterm" or "iTerm.app".  "xterm" and
-   "xterm-256color" are incorrect; for starters they do not include
-   iTerm.app's status line capability.
- - The correct $TERM for Terminal.app is "nsterm".  "vt100", "xterm", and
-   "xterm-256color" are incorrect; for starters they do not include
-   Terminal.app's status line capability or correctly describe its
-   cursor-addressed mode.
- - The correct $TERM for tmux is "tmux" or "tmux-256color".  "screen" is
-   incorrect; for starters it does not include tmux's italics and status line
-   capabilities or correctly describe how to set inverse video.

Subject: [PATCH 64/66] tui: Switch terminal keyboard mode properly.

The terminfo doco explicitly states that it covers the case where the
terminal is in application cursor/keypad (i.e. "keypad transmit") mode,
and not where it is in normal cursor/keypad (i.e.  "keypad local") mode.
Full screen applications like nvim must switch to and from keypad
transmit mode when expecting the control sequences given by terminfo.
