=head1 NAME

Mojo::Loader - Load all kinds of things

=head1 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');
  }

=head1 DESCRIPTION

L<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 C<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 C<@@>, 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.

=head1 FUNCTIONS

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

=head2 data_section

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

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

# List embedded files
  say for keys %{data_section 'Foo::Bar'};

=head2 file_is_binary

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

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

=head2 find_packages

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

Search for packages in a namespace non-recursively.

=head2 find_modules

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

Search for modules in a namespace non-recursively.

=head2 load_class

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

Load a class and catch exceptions, returns a false value if loading was successful, a true value if the class was not
found, or a L<Mojo::Exception> object if loading failed. Note that classes are checked for a C<new> method to see if
they are already loaded, so trying to load the same class multiple times may yield different results.

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