Easy way to print Perl array? (with a little formatting)

Question

Is there an easy way to print out a Perl array with commas in between each element?

Writing a for loop to do it is pretty easy but not quite elegant....

Answer 1

Using Data::Dumper :

use strict;
use Data::Dumper;

my $GRANTstr = 'SELECT, INSERT, UPDATE, DELETE, LOCK TABLES, EXECUTE, TRIGGER';
$GRANTstr    =~ s/, /,/g;
my @GRANTs   = split /,/ , $GRANTstr;

print Dumper(@GRANTs) . "===\n\n";

print Dumper(\@GRANTs) . "===\n\n";

print Data::Dumper->Dump([\@GRANTs], [qw(GRANTs)]);

Generates three different output styles:

$VAR1 = 'SELECT';
$VAR2 = 'INSERT';
$VAR3 = 'UPDATE';
$VAR4 = 'DELETE';
$VAR5 = 'LOCK TABLES';
$VAR6 = 'EXECUTE';
$VAR7 = 'TRIGGER';
===

$VAR1 = [
          'SELECT',
          'INSERT',
          'UPDATE',
          'DELETE',
          'LOCK TABLES',
          'EXECUTE',
          'TRIGGER'
        ];
===

$GRANTs = [
            'SELECT',
            'INSERT',
            'UPDATE',
            'DELETE',
            'LOCK TABLES',
            'EXECUTE',
            'TRIGGER'
          ];
