Re^3: updating a variable call in a hash table

I guess here's an even simpler example:

$color = "green";
$text = "The color is $color"
$color = "blue";
print $text;

I want the output to be "The color is blue". How do I make that happen?

It doesn't matter where your template string comes from, it's still a string containing some markup. It's the same question with the same answer: use a templating system. Consider: `use warnings; use strict; for my $color (qw(green blue red puce)) { my $text = "The color is COLOR\n"; $text =~ s/COLOR/$color/g; print $text; }` [download] prints: `The color is green The color is blue The color is red The color is puce` [download] Perl's payment curve coincides with its learning curve.

It's the same question with the same answer: use a templating system. Consider:

use warnings;
use strict;

for my $color (qw(green blue red puce)) {
    my $text = "The color is COLOR\n";

    $text =~ s/COLOR/$color/g;
    print $text;
}

prints:

The color is green
The color is blue
The color is red
The color is puce
