Re: Reading File Into Array

There are at least a couple of different ways to do this.

Here's one example using Path::Tiny:

use strict;
use warnings;

use feature 'say';

use Path::Tiny;

my $file = 'test_file.txt';

my @lines = path($file)->lines({chomp => 1});

my $line_number = 1;
foreach my $line (@lines) {
    say "$line_number: $line";
    $line_number++;
}

Here's an example that uses Tie::File:

use strict;
use warnings;

use feature 'say';

use Tie::File;

my $file = 'test_file.txt';

tie @lines, 'Tie::File', $file or die "Unable to open file '$file': $!
+";

my $line_number = 1;
foreach my $line (@lines) {
    say "$line_number: $line";
    $line_number++;
}

Here's an example that does not use any modules:

use strict;
use warnings;

use feature 'say';

my $file = 'test_file.txt';

open(my $fh, "<", $file) or die "Unable to open file '$file': $!";
my $data;
{
    local $/;
    undef $/;
    $data = <$fh>;
}
close($fh);
my @lines = split /\n/,$data;

my $line_number = 1;
foreach my $line (@lines) {
    say "$line_number: $line";
    $line_number++;
}
