John,
Ugh! What a mess this stuff is. The documentation is terse and ambiguous so I
just went back to the kernel source. Clearly you're using a different
configuration than mine in some regard since our results differ. My best guess
for you to get the final results you want is to add 15 to each of the 2nd and
3rd parameters in order to get black text. This should actually result in
dimmed text so it'll appear grey. To get dark black, change the first parameter
to 16 (from 120). So based on the results you report, something like:
setw -ga terminal-overrides
',*:Cc=\E[?16;%p1%s;255c:Cr=\E[?16;95;255c:civis=\E[?25l:cnorm=\E[?25h:cvvis=\E[?25h,'
And then add 15 to each of the values you were passing to vim.. so:
let &t_EI="\<esc>]12;31\007"
But i've lost confidence in my local results matching yours, so you'll just
have to play with it a bit. The main takeaway is that the 3rd parameter is
logically OR'd with the attribute bits and then parameter 2 is XOR'd. so in
the example above we're first forcing all attribute bits on (ie. with 255) and
then turning some of those bits off with whatever we set in parameter 2. The
8 attribute bits are broken into 2, 4-bit nibbles, one for the foreground and
the other for the background.
Good luck,
Sean
