We''ve had other people get it working on Cygwin before, I believe. Are you running this within Cygwin''s rxvt? What if you modify lib/sup/colormap.rb so that NUM_COLORS=15? -- William <wmorgan-sup at masanjin.net>
Reformatted excerpts from Dan Falcone''s message of 2009-10-12:> Honestly, it''s probably an issue with my setup... is there a guide > anywhere on how to get sup running in cygwin? Maybe I''m missing a > required package?There''s no guide per se. Other people have definitely made it work in the past. Are you able to get other color curses programs to work? I suspect it''s not a Sup issue per se, but I''m not that familiar with the intricacies of Cygwin. -- William <wmorgan-sup at masanjin.net>

What does this program print? require ''rubygems'' require ''ncurses'' x = begin Ncurses::initscr(); Ncurses::has_colors?() ensure Ncurses::endwin(); end puts x If it prints true, then, if you look in the contents of the gem (wherever that is on your system), there should be an examples/ directory. If you run examples/tlock.rb or examples/rain.rb, (probably with ruby -rubygems), do you see color? -- William <wmorgan-sup at masanjin.net>
Hi William, Sorry I didn''t get back to you sooner. I finally got back around to playing with this again. Here are the answers to your questions:>gem list --local | grep cursencurses (0.9.1) The test script prints: true The ncurses examples all seem to work and display color. I did have to edit them to add require ''rubygems'' at the top. I also tried playing with the sup code a bit. If I comment out lines 133-4 in lib/sup/colormap.rb: # Curses.init_pair id, fg, bg or raise ArgumentError, # "couldn''t initialize curses color pair #{fg}, #{bg} (key #{id})" sup loads, but everything is in black and white and a bit difficult to read. I also tried uncommenting that, then changing Curses to Ncurses so it looks like this: Nurses.init_pair id, fg, bg or raise ArgumentError, "couldn''t initialize curses color pair #{fg}, #{bg} (key #{id})" sup loads with that as well, and displays some color, but most of the screen is unreadable (I''m guessing it''s displaying as white text on white background). Any ideas? I tried changing more things from Curses to Ncurses, but that quickly started generating method undefined errors. Thanks!
