I'm making a Dungeons & Dragons die-rolling program in which the user is asked for input over and over until Ctrl-C. The source code is here:
#!/usr/bin/perl
print "Input the dice and modifier you want to roll like this: 2d9+100
+. To quit, press Ctrl-C.\n";
while (1) {
my $dice = <>;
my @arr = split (/d/, $dice);
my @arr2 = split (/\+/, $arr[1]);
for my $i (1 .. $arr[0]){
print ((int(rand($arr2[0] - 1)) + 1 + $arr2[1]), "\n");}}
I want to add input history to this program; that is, when a user presses the up-arrow, the program provides the last input, just like in interactive ksh/csh/bash. How would I go about this?
$thanks++, zsl
