I can do this to convert a scalar string into an array of individual
characters:
my @characters = split (undef, $string); #or ('', $string)
But if I get close to my screen, I detect a faint odor of bad code. Is
there a better way?
Is there something you want to apply to each character in return?
Would iterating over each character be acceptable?
#!/usr/bin/perl
use warnings;
use strict;
my $foo = 'ffooooo';
do_something($1) while $foo =~ m{(.)}g;
To be equivalent you would have to include the /s option:
do_something($1) while $foo =~ m{(.)}sg;
And you don't really need the capturing parentheses:
do_something($_) for $foo =~ m{.}sg;
