I went with the first option.
I was glad you gave me choices ;).
The first one was
exactly the behaviour I was looking for.
You seen to dislike this option but I fail to see why.
Here's the code I used, based on
all the help in this
thread:
use strict;
my $dict = "/usr/dict/words";
my ($set, $cur, $end) = (0, 1, 2);
for my $i (1..30) {
printf "word #%2d: \%s\n", $i, &pick_word(10);
}
sub pick_word {
my $reqsize = shift;
my $ret = "";
my $die = 0;
open DICT, "$dict" or die "redmist code: $!";
seek DICT, rand(-s $dict), $set;
<DICT>; # this get's us to the start of the next line.
TOP: while (<DICT>) {
($ret = $1 and last) if /^(\w{$reqsize})$/;
}
if(length($ret) != $reqsize) {
# ok, go back around
seek DICT, 0, $set;
# but remember we were already here ...
die "Word too big, aaaaaaaahhhhhh!" if $die;
$die = 1;
goto TOP;
}
close DICT;
return $ret;
}
