Mojo::Loader - Loader

SYNOPSIS

use Mojo::Loader qw(data_section find_modules load_class);

# Find modules in a namespace
for my $module (find_modules 'Some::Namespace') {

  # Load them safely
  my $e = load_class $module;
  warn qq{Loading "$module" failed: $e} and next if ref $e;

  # And extract files from the DATA section
  say data_section($module, 'some_file.txt');
}

DESCRIPTION

Mojo::Loader is a class loader and plugin framework. Aside from finding modules and loading classes, it allows multiple files to be stored in the DATA section of a class, which can then be accessed individually.

package Foo;

1;
__DATA__

@@ test.txt
This is the first file.

@@ test2.html (base64)
VGhpcyBpcyB0aGUgc2Vjb25kIGZpbGUu

@@ test
This is the
third file.

Each file has a header starting with @@, followed by the file name and optional instructions for decoding its content. Currently only the Base64 encoding is supported, which can be quite convenient for the storage of binary data.

FUNCTIONS

Mojo::Loader implements the following functions, which can be imported individually.

data_section

my $all   = data_section 'Foo::Bar';
my $index = data_section 'Foo::Bar', 'index.html';

Extract embedded file from the DATA section of a class, all files will be cached once they have been accessed for the first time.

say for keys %{data_section 'Foo::Bar'};

file_is_binary

my $bool = file_is_binary 'Foo::Bar', 'test.png';

Check if embedded file from the DATA section of a class was Base64 encoded.

find_packages

my @pkgs = find_packages 'MyApp::Namespace';

Search for packages in a namespace non-recursively.

find_modules

my @modules = find_modules 'MyApp::Namespace';

Search for modules in a namespace non-recursively.

load_class

my $e = load_class 'Foo::Bar';

Load a class and catch exceptions. Note that classes are checked for a new method to see if they are already loaded.

if (my $e = load_class 'Foo::Bar') {
  die ref $e ? "Exception: $e" : 'Not found!';
}
