Mojolic...Command(3)

💖 NAME

okay bestie, this is the manual page for Mojolicious::Command — the command base class. The header/manual name is Mojolic...Command(3), and it’s from User Contributed Perl Documentation. It’s the abstract blueprint energy for Mojolicious commands, not a full app all by itself.

✨ SYNOPSIS ✨

Here’s the code starter pack, exactly as it appears — no cap, do not rename anything:

# Lowercase command name
package Mojolicious::Command::mycommand;
use Mojo::Base 'Mojolicious::Command', -signatures;

# Short description
has description => 'My first Mojo command';

# Usage message from SYNOPSIS
has usage => sub ($self) { $self->extract_usage };

sub run ($self, @args) {

  # Magic here! :)
}

=head1 SYNOPSIS

🦋 DESCRIPTION 🦋

Mojolicious::Command is an abstract base class for Mojolicious commands.

For a list of commands that are available by default, see COMMANDS in Mojolicious::Commands.

🎀 ATTRIBUTES 🎀

Mojolicious::Command implements the following attributes.

🌸 app

my $app  = $command->app;
$command = $command->app(Mojolicious->new);

Application for command, defaults to a Mojo::HelloWorld object. Note that this attribute is weakened.

Introspect example, because sometimes you just gotta peek:

# Introspect
say "Template path: $_" for @{$command->app->renderer->paths};

🍓 description

my $description = $command->description;
$command        = $command->description('Foo');

Short description of command, used for the command list.

🧚 quiet

my $bool = $command->quiet;
$command = $command->quiet($bool);

Limited command output.

💜 template

my $template = $command->template;
$command     = $command->template({vars => 1});

Attribute values passed to Mojo::Template objects used to render templates with render_data, defaults to activating vars.

🌈 usage

my $usage = $command->usage;
$command  = $command->usage('Foo');

Usage information for command, used for the help screen.

🔥 METHODS 🔥

Mojolicious::Command inherits all methods from Mojo::Base and implements the following new ones.

💅 chmod_file

$command = $command->chmod_file('/home/sri/foo.txt', 0644);

Change mode of a file.

🫶 chmod_rel_file

Portably change mode of a file relative to the current working directory.

🎀 create_dir

$command = $command->create_dir('/home/sri/foo/bar');

Create a directory if it does not exist already.

🦋 create_rel_dir

$command = $command->create_rel_dir('foo/bar/baz');

Portably create a directory relative to the current working directory if it does not exist already.

⭐ extract_usage

my $usage = $command->extract_usage;

Extract usage message from the SYNOPSIS section of the file this method was called from with extract_usage in Mojo::Util.

🌸 help

$command->help;

Print usage information for command.

🍓 rel_file

my $path = $command->rel_file('foo/bar.txt');

my $data = $command->render_data('foo_bar', @args);
my $data = $command->render_data('foo_bar', {foo => 'bar'});

Render a template from the DATA section of the command class with Mojo::Loader and Mojo::Template. The template can be configured with template.

💜 render_to_file

$command = $command->render_to_file('foo_bar', '/home/sri/foo.txt');
$command = $command->render_to_file('foo_bar', '/home/sri/foo.txt', @args);
$command = $command->render_to_file(
  'foo_bar', '/home/sri/foo.txt', {foo => 'bar'});
