Declaring an Array Using Character Classes

[simpzoid]

Dear All, I am looking to create an array like this:

my @arry = ("a","b","c","d","e","f","g","h","i","j","k","l","m","n","o","p","q","r","s","t","u","v","w","x","y","z","0","1","2","3","4","5","6","7","8","9");

but am struggling to find a shorthand way of doing this. Surely there must be a way of doing this with character classes.

G'day simpzoid,

Perhaps something like this:

$ perl -Mstrict -Mwarnings -e '
my @arry = ("a" .. "z", 0 .. 9);
print "@arry\n";
'
a b c d e f g h i j k l m n o p q r s t u v w x y z 0 1 2 3 4 5 6 7 8 
+9

Wow, thanks for the quick reply. That worrks for me.

Array with uppercase/lowercase alphabet and -10 to 10 using Range Operators:

$ perl -W -Mstrict -E 'my @alphanum = ( "A" .. "Z", "a" .. "z", -10 ..
+ 10 ); say "@alphanum"'
A B C D E F G H I J K L M N O P Q R S T U V W X Y Z a b c d e f g h i 
+j k l m n o p q r s t u v w x y z -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0 1

Hello Scott,

The replies you've already received do a great job of creating the array you asked for. I'm a little bit curious on what your intended use for this array is? I ask because I'm trying to imagine a use for this, and the only one I could come up with would be something like a password (or other random string) generator. On the chance that is what you're doing, you may want to check out CPAN modules like the following:

• String::MkPasswd
• Crypt::GeneratePassword
• ...

The list is actually quite lengthy, so I refer you to the recent research of Neil Bowers: CPAN modules for generating passwords

My apologies of course if I'm completely off the mark, but again I'm curious about your use case if you'd like to share.

Hi,

probably something like this:

my @arry = grep { is_of_some_class($_) } map { chr $_ } (1..255);

Best regards
