NAME

Data::Object::Data

ABSTRACT

Data-Object Data Extraction Class

SYNOPSIS

  use Data::Object::Data;

  my $data = Data::Object::Data->new;

This example is extracting from the main package.

  use Data::Object::Data;

  my $data = Data::Object::Data->new(from => 'Example::Package');

This example is extracting from a class.

  use Data::Object::Data;

  my $data = Data::Object::Data->new(file => 'lib/Example/Package.pm');

This example is extracting from a file.

  use Data::Object::Data;

  my $data = Data::Object::Data->new(data => [,'...']);

This example is extracting from existing data.

  package Command;

  use Data::Object::Data;

  =pod help

  fetches results from the api

  =cut

  my $data = Data::Object::Data->new(
    from => 'Command'
  );

  my $help = $data->content('help');
  # fetches results ...

  my $token = $data->content('token');
  # token: the access token ...

  my $secret = $data->content('secret');
  # secret: the secret for ...

  my $flags = $data->contents('flag');
  # [,...]

  __DATA__

  =flag secret

  secret: the secret for the account

  =flag token

  token: the access token for the account

  =cut

DESCRIPTION

This package provides methods for parsing and extracting pod-like data sections from any file or package. The pod-like syntax allows for using these sections anywhere in the source code and Perl properly ignoring them.

INHERITANCE

This package inherits behaviors from:

Data::Object::Base

LIBRARIES

This package uses type constraints defined by:

Data::Object::Library

METHODS

This package implements the following methods.

content

  content(Str $arg1) : Str

The content method returns the pod-like section where the name matches the given string.

content example

  =pod help

  Example content

  =cut

  # given $data

  $data->content('help');

  # Example content

contents

  contents(Str $arg1) : ArrayRef

The contents method returns all pod-like sections that start with the given string, e.g. pod matches =pod foo. This method returns an arrayref of data for the matched sections.

contents example

  =pod help

  Example content

  =cut

  # given $data

  $data->contents('pod');

  # [,...]

data

  data(Str $arg1) : ArrayRef

The data method returns the contents from the DATA and END sections of a package.

data example

  # given $data

  $data->data($class);

  # ...

file

  file(Str $arg1) : ArrayRef

The file method returns the contents of a file which contains pod-like sections for a given filename.

file example

  # given $data

  $data->file($args);

  # ...

from_data

  from_data(Str $arg1) : Str

The from_data method returns content for the given class to be passed to the constructor. This method isn't meant to be called directly.

from_data example

  # given $data

  $data->from_data($class);

  # ...

from_file

  from_file(Str $arg1) : Str

The from_data method returns content for the given file to be passed to the constructor. This method isn't meant to be called directly.

from_file example

  # given $data

  $data->from_file($file);

  # ...

item

  item(Str $arg1) : HashRef

The item method returns metadata for the pod-like section that matches the given string.

item example

  =pod help

  Example content

  =cut

  # given $data

  $data->item('help');

  # {,...}

list

  list(Str $arg1) : ArrayRef

The list method returns metadata for each pod-like section that matches the given string.

list example

  =pod help

  Example content

  =cut

  # given $data

  $data->list('pod');

  # [,...]

parser

  parser(Str $arg1) : ArrayRef

The parser method extracts pod-like sections from a given string and returns an arrayref of metadata.

parser example

  # given $data

  $data->parser($string);

  # [,...]

pluck

  pluck(Str $arg1, Str $arg2) : HashRef

The pluck method splices and returns metadata for the pod-like section that matches the given list or item by name.

pluck example

  =pod help

  Example content

  =cut

  # given $data

  $data->pluck('item', 'help');

  # {,...}
