Nethack in colour with System V r3.2 curses
Pim Zandbergen
release of nethack on ISC UNIX (System V/386 release 3.2).
Everything runs just fine, but it lacks the colours that
were promised when defining TEXTCOLOR in include/unixconf.h.
This is no curses/terminfo problem, as other applications,
like u386mon, posted recently to comp.sources.misc work
just fine with colour.
Any clue anybody?

Not that I ever have time to play games, but I just solved this problem
under ESIX. I had to do the following:
1) change the ANSI color escape sequences in termcap.c
to specify the color first, and then the intensity second.
Note that Nethack is incredibly "poortable" and therefore
finding the hunk of code which UNIX uses is nontrivial.
Anyhow, it does them with lines similar to:
sprintf(hilites[c+BRIGHT],"\033[1;3%dm",c);
but you need something like
sprintf(hilites[c+BRIGHT],"\033[3%dm\033[1m",c);
2) Either set the "standout" option, or remove some checks in pri.c
which specify no colors unless flags.standout is on. Perhaps this
doesn't matter. 1) is the main thing.
And gee, the money is really more satisfying in bright yellow than it is
in drab white...
Of course, I don't know if this same trick works under ISC or SCO.

The fix to this is incredibly simple, but doesn't appear to be documented
anywhere in the code or release notes for nethack...
In your .profile, you will need to initialize a variable called
NETHACKOPTIONS so that it looks similar to:
NETHACKHOPTIONS="standout";export NETHACKOPTIONS
If you've actually compiled everything correctly, and your terminfo supports
colour displays, then you will now have a full colour nethack. (And your
terminfo DOES support colour, because I'm running the same OS with full-colour
nethack running just fine...)
You can set other nifty items using NETHACKOPTIONS as well, but most of
those are pretty well documented.
