Hello,
I would like to emulate the good old Pascal ‘loop until keypressed’ code
snippet:
repeat
write(“Hello”);
until keypressed;
(also the borland c/c++ function kbhit() was similar).
Also I would like to continue the loop in the same manner unless the
user pressed a specific key.
Since ansi C/C++ does not support this functionality, I guess it is not
supported by Ruby either - and after searching around a bit I could not
find some good substitute yet.
I do no want a general solution - it is enough if it will run under
linux. It is also not a problem if it will require a gem or anything
else (like libcurses-ruby or something).
Any ideas?
TIA
