Package: crawl Version: 2:0.2.7-1 Severity: normal I have built xterm with 256 colour support from upstream xterm-227 source. Now when I run crawl in that, with TERM=xterm-256color, everything that should have a light foreground colour instead gets displayed in bold with the corresponding dark foreground colour. Most importantly, things that should be dark grey become black and thus invisible. This affects for instance those parts of the map that are not in sight.
The cause appears to be this xterm vs. xterm-256color difference
in terminfo:
setaf: '\E[3%p1%dm', '\E[38;5;%p1%dm'.
If I run printf "\033[0;30;1ma\033[0;38;5;0;1mb\033[mc\n",
then the "a" is dark grey but the "b" is black. Apparently, the
boldColors resource of xterm affects only SGR values 30 to 37,
and not colours set with the 38;5 syntax.
Possible fixes:
(a) Change Crawl to detect that the terminal directly supports 16
or more colours, and then use those colours via the setaf
capability, instead of assuming that the bold attribute also
changes the colour.
(b) Change Crawl to send "\E[30m" for black if the terminfo
indicates "\E[38;5;0m". Not a good idea: I normally run things
in Screen, which would map the "\E[30m" to "\E[38;5;0m" anyway.
(c) Change xterm to respect the boldColors resource also when the
foreground colour is set with SGR 38;5. I think boldColors is
really a hack and its effects should not be extended like this.
I could try patching Crawl for solution (a) in a few weeks,
but it would be nice if you could first comment on whether
you consider that a reasonable way to fix the problem.
