Hi
I've seen several times users being confused about
how to set up t_8f and t_8b, needed for some terminals
to get 'termguicolors' feature to work. Copy/pasting the
following 2 lines from :help xterm-true-color does
not work, since ^[ needs to be typed as a single Escape
char:
set t_8f=^[[38:2:%lu:%lu:%lum
set t_8b=^[[48:2:%lu:%lu:%lum
Attached patch attempts to clarify how to set t_8f and t_8b.
I've also been confused myself with getting 'termguicolors'
to work, as it works for some terminals but not others.
How about listing in help files terminals where 'termguicolors'
is known to work and terminal where it known to not work?
I've only tried 'termguicolors' on xubuntu-14.04 and xubuntu-15.10:
'termguicolors' did not work with:
- xfce4-terminal 0.6.3 (xubuntu-14.04, xubuntu-15.10)
- gnome-terminal 3.6.2 (xubuntu-14.04)
- MATE Terminal 1.10.1 (xubuntu-15.10)
'termguicolors' worked with:
- XTerm (297, xubuntu-14.04)
- gnome-terminal (3.16.2, xubuntu-15.10)
I'm hoping that support for 'termguicolors' is better
in more recent distributions.
Regards
Dominique
