f4c7141f5d Do not lazily use BUFSIZ for "I don't care what size" when building 
strings because it is only guaranteed to be 256 bytes and even the
default 1024 is not always enough. Reported by Gregory Pakosz.

bc0e527f32 Support for extended underline styles on terminals which offer them, 
enabled by adding the Smulx capability with terminal-overrides (add
something like ',vte*:Smulx=\E[4\:%p1%dm'). GitHub issue 1492.

f915a4bf0c Handle terminfo colors > 256 correctly, GitHub issue 1337. 2018-05-07 13:39:09 +00:00
nicm
fe7a871a23 Upstream ncurses has introduced terminfo capabilities to specify RGB 
colour ("true" or "direct" colour). These consist of new entries (such
as "xterm-direct") which have a different setaf/setab implementation,
colors and pairs set to 0x1000000 and 0x10000, and a new RGB flag.

The setaf/setab definitions seem to be geared towards what ncurses (or
emacs maybe) needs, in that the new versions do only ANSI and RGB
colours (they can't be used for the 256 colour palette); they rely on
the silly ISO colon-separated version of SGR; and they use a weird
multiplication scheme so they still only need one argument. The higher
values of colors and pairs require a recent ncurses to parse.

tmux can use the RGB flag to detect RGB colour support (keeping the old
Tc extension for backwards compatibility for now). However, as we still
want to send 256 colour information unchanged when possible, the new
setaf/setab are awkward. So when RGB is present, reserve setaf/setab
only for ANSI colours and use the escape sequences directly for 256 and
RGB colours. (To my knowledge no recent terminal uses unusual escape
sequences for these in any case.)

7eb496c00c Look for setrgbf and setrgbb terminfo extensions for RGB colour. This is 
the most reasonable of the various (some bizarre) suggestions for
capabilities.

1ba7f1d03f Check the terminfo(5) U8 capability and disable using UTF-8 for ACS if 
it is present and zero. This is useful for users with terminals or fonts
that do not correctly support UTF-8 line drawing characters. GitHub
issue 927, reported by Hiroaki Yamazoe and Akinori Hattori.

df3ab87964 Add support for the strikethrough attribute (SGR 9), using the new smxx 
terminfo capability. This means there are now nine attribute bits, so
anything above 0xff uses an extended cell.

427b820426 Support for RGB colour, using the extended cell mechanism to avoid 
wasting unnecessary space. The 'Tc' flag must be set in the external
TERM entry (using terminal-overrides or a custom terminfo entry), if not
tmux will map to the closest of the 256 or 16 colour palettes.

Mostly from Suraj N Kurapati, based on a diff originally by someone else.

2056a9ef9e Drop explicit support for F13-F20 and change to match the xterm terminfo 
entry:

        F13-F24 are S-F1 to S-F12
        F25-F36 are C-F1 to C-F12
        F37-F48 are C-S-F1 to C-S-F12
        F49-F60 are M-F1 to M-F12
and     F61-F63 are M-S-F1 to M-S-F3

This should be no difference for applications inside tmux, but means
that any key binding for F13 will need to be replaced by S-F1 and so on.

13441e8cb8 The actual terminfo entries we ended up with for cursor changes are Cs, 
Ce, Ss and Se (not Cc, Ce, Cs, Csr). So use and document these instead
of the ones we were using earlier.
