27.0.50; Emacs TERMINFO "xterm-direct" "efaq" example not working |
|
Date: |
Sun, 11 Feb 2018 21:09:40 -0500 |
Hi,
The example in the "efaq" Info file gives the following
TERM=xterm-direct emacs -nw
When I execute this, as stated, I get an Emacs session
WITHOUT any colors -- even "M-x list-colors-display"
does not show any colors.
However, if I change this to the following, I see colors
displayed:
TERM=xterm-direct2 emacs -nw
[Note the "2" in "xterm-drect2"]
Here is the definition for the setab/setaf parameters for
each:
xterm-direct2:
# Emacs 26.1 and later support direct color mode in terminals, using a
# combination of user-defined capabilities and ncurses-dependent function
# calls. We will not include that here.
#
# Here is a first revision, which (disregarding the reuse of colors 1-7 which
# is of interest only to the numerically illiterate), is compatible with other
# terminal descriptions written for curses. It relies upon the extended range
# for numeric capabilities provided in ncurses 6.1:
xterm+direct2|xterm with direct-color indexing,
[...]
xterm-direct2|xterm with direct-color indexing (old),
use=xterm+direct2, use=xterm+titlestack, use=xterm,
[...]
setab=\E[%?%p1%{8}%<%t4%p1%d%e48\:2\:%p1%{65536}%/%d\:%p1%{256}%/%{255}%&%d\:%p1%{255}%&%d%;m,
setaf=\E[%?%p1%{8}%<%t3%p1%d%e38\:2\:%p1%{65536}%/%d\:%p1%{256}%/%{255}%&%d\:%p1%{255}%&%d%;m,
xterm-direct:
# That in turn had a problem: in the original patch submitted for KDE konsole
# in 2006, the submitter and the developer alike overlooked a "color space
# identifier" parameter. This version provides for that parameter:
xterm+direct|xterm with direct-color indexing,
[...]
setab=\E[%?%p1%{8}%<%t4%p1%d%e48\:2\:\:%p1%{65536}%/%d\:%p1%{256}%/%{255}%&%d\:%p1%{255}%&%d%;m,
setaf=\E[%?%p1%{8}%<%t3%p1%d%e38\:2\:\:%p1%{65536}%/%d\:%p1%{256}%/%{255}%&%d\:%p1%{255}%&%d%;m,
Between the two ("xterm-direct"and "xerm-direct2"), I see
the diffeence in at least "\:2\:\:" and "\:2\:".
respectively -- "xterm-direct" has an additioal "\:"
So, should Emacs be changed to accommadate the missing
parameter ("\:" as in "xterm-direct")??
Or should the information in "efaq" be changed to specify
"xterm-direct2"?
Or...?
Can anyone else confirm that colors are not displayed
in Emacs TTY when using TERMINFO's 6.1 definition of
"xterm-direct" (setab/setaf)?
Thanks.
