Command line application template for Perl

Implement CLI application by editing main.pl.
You may add new files to keep your code clean, if it is allowed in your challenge.

How to get input parameters

In main.pl, there is a function called main, which receives command line arguments as-is.

sub main {
    # code to run ...
}

main(@ARGV);

How to output result

You can use the standard print() method to output results to standard output.

print("text to output");

Install External Libraries

To install external libraries, write dependencies in cpanfile. Dependencies will be install by using Carton.

Following sample from cpanfile has been verified to installs dependencies as expected.

requires 'Plack', '1.0'; # 1.0 or newer
requires 'JSON', '>= 2.00, < 2.80';
 
recommends 'JSON::XS', '2.0';
conflicts 'JSON', '< 1.0';
 
on 'test' => sub {
      requires 'Test::More', '>= 0.96, < 2.0';
        recommends 'Test::TCP', '1.12';
};
 
on 'develop' => sub {
      recommends 'Devel::NYTProf';
};
 
feature 'sqlite', 'SQLite support' => sub {
      recommends 'DBD::SQLite';
};
