Re: [sup-talk] curses exception

[Dan Falcone <danfalcone@gmail.com>]

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 curse
ncurses (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!
Dan

Hm. What version of the ncurses gem do you have? (gem list --local
should tell you.)

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?
