Hm.... it seems like you're right, the colors in Konsole are ever so
slightly off... It looks as though they're stepping evenly...
xterm's steps are 00, 5F, 87, AF, D7, FF ; it favors the lighter colors.
konsole's are 00, 33, 66, 99, CC, FF ; it favors being even...
(I found it at TECommon.h:149 after searching harder)
So, I would certainly welcome some advice on how querying
can be done reasonably...
Gnome-terminal and Konsole, at least, do not seem to be able
to report back their colors... So, I guess one (pseudocode)
approach is...
if $TERM =~ 'screen'
prefix = "\eP"
suffix = "\e\\"
endif
resp = send_query(prefix + "\e]4;17;?\007" + suffix)
if resp != ""
palette = query_active_palette() # Repeatedly calls send_query
else
# No answer: assume default based on &t_Co
if &t_Co == 88
palette = default_urxvt
else
if $KONSOLE_DCOP_SESSION == ""
palette = default_xterm_gnome_terminal_putty
else
palette = default_konsole_rxvt
endif
endif
endif
Any thoughts? At the very least, this fails where a user launches
gnome-terminal from konsole, since KONSOLE_DCOP_SESSION
would have been exported... Is there a better way to tell them
apart? Why can't they use $TERM right... :-/

Here's hoping. :)
