Scalar::Dynamizer

Scalar::Dynamizer enables the creation of dynamic scalars that automatically recompute their values whenever they are accessed. This module simplifies working with dynamically evaluated scalars using Perl's tie mechanism and operator overloading, making it intuitive and transparent to implement scalars that depend on the program's state at the time of access.

Dynamic scalars are particularly useful for counters, timestamps, or real-time data from external sources such as databases or APIs.

Installation

To install this module, run the following commands:

perl Makefile.PL
make
make test
make install

Usage

Here’s a quick example:

use Scalar::Dynamizer qw(dynamize);

my $count = 0;

# Create a dynamic scalar
my $counter = dynamize { ++$count };

print $counter;             # 1
print $counter * 100;       # 200
print "Count is $counter";  # "Count is 3"

See the examples/ directory for additional examples.
