How can I get a single keyboard character from the terminal with Ruby without pressing enter?
I tried Curses::getch, but that didn't really work for me.

#!/usr/bin/ruby
begin
system("stty raw -echo")
str = STDIN.getc
ensure
system("stty -raw echo")
end
p str.chr
(Tested on my OS X system, may not be portable to all Ruby platforms). See http://www.rubyquiz.com/quiz5.html for some additional suggestions, including for Windows.
