How to ReadKey on those weird ones...

[PipTigger]

I've tried to use Term::ReadKey to get a single key and I have the latest one installed but I get a segfault everytime I try to ChangeMode... so I found HotKey.pm which serves my text character input needs fine... but how does one go about reading special characters like Controls and Alts and Arrow keys etc.? Please help! Thanks. TTFN.

You can use to Term::ReadKey to read raw keystrokes. The follow code prints out an interger value coresponding to each keystroke. While it doesn't let you check the conrol keys without another key, it does let you tell the difference between control+key, and alt+key, or to detect the arrow keys.

The following code tested under linux. If you are using another platform, be sure to RTM first.

Note also that if you run this code, you will have to kill the process remotely. If that doesn't make any sense, change ReadMode before you run it.

use strict;
use Term::ReadKey;
ReadMode 5;
while (my $key = ReadKey(0)){
    print ord($key)
}
ReadMode 0;

update: have you tried rebuilding and/or reinstalling Term::ReadKey? It is a very important module, I would focus on getting it to work instead of replacing it.

Is it any call to ReadMode that crashes?

If you install via perl -MCPAN -e'shell' then it will do a number of tests as it installs.
