            Bug ID: 371919
           Summary: export COLORTERM=3Dtruecolor
           Product: konsole
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: UNCONFIRMED
          Severity: wishlist
          Priority: NOR
         Component: general
          Assignee: konsole-devel@kde.org
          Reporter: egmont@gmail.com
  Target Milestone: ---

Konsole supports true colors, however, there's no official way of advertisi=
ng
this feature.

Unfortunately the maintainer of ncurses and terminfo is not interested at a=
ll
in adding this possibility to terminfo, see e.g.
https://lists.gnu.org/archive/html/bug-ncurses/2016-08/msg00036.html.

S-Lang, on the other hand, has just released its version 2.3.1 with true co=
lor
support. Due to the lack of an "official" way of checking for this feature,=
 the
author decided to look at the COLORTERM environment variable expecting it t=
o be
set to either "truecolor" or "24bit". See
http://lists.jedsoft.org/lists/slang-users/2016/0000014.html.

The probably most well-known application using S-Lang (by default, with ncu=
rses
being an option too) is Midnight Commander. It has a patch on its way to
support true colors, see https://www.midnight-commander.org/ticket/3145.

VTE (gnome-terminal et al) sets this environment variable beginning with
version 0.44, see https://bugzilla.gnome.org/show_bug.cgi?id=3D754521.

Please make konsole set this variable. This is required for a forthcoming
version of Midnight Commander to support true colors out of the box without=
 any
kind of hacking. Also, being consistent across terminal emulators is the be=
st
we could do to make this a de facto standard and encourage the authors of o=
ther
applications that support true colors to also check for this environment
variable rather than everyone coming up with their own individual hacks.
