ABSTRACT

    Podish Parser for Perl 5

SYNOPSIS

      package main;
    
      use Data::Object::Data;
    
      my $data = Data::Object::Data->new(
        file => 't/Data_Object_Data.t'
      );

DESCRIPTION

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

ATTRIBUTES

    This package has the following attributes:

 data

      data(Str)

    This attribute is read-only, accepts (Str) values, and is optional.

 file

      file(Str)

    This attribute is read-only, accepts (Str) values, and is optional.

 from

      from(Str)

    This attribute is read-only, accepts (Str) values, and is optional.

METHODS

    This package implements the following methods:

 content

      content(Str $name) : ArrayRef[Str]

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

    content example #1

        # =name
        #
        # Example #1
        #
        # =cut
        #
        # =name
        #
        # Example #2
        #
        # =cut
      
        my $data = Data::Object::Data->new(
          file => 't/examples/content.pod'
        );
      
        $data->content('name');
      
        # ['Example #1']

 contents

      contents(Str $list, Str $name) : ArrayRef[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. Optionally, you can filter
    the results by name by providing an additional argument.

    contents example #1

        # =name example-1
        #
        # Example #1
        #
        # =cut
        #
        # =name example-2
        #
        # Example #2
        #
        # =cut
      
        my $data = Data::Object::Data->new(
          file => 't/examples/contents.pod'
        );
      
        $data->contents('name');
      
       # [['Example #1'], ['Example #2']]

 item

      item(Str $name) : HashRef

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

    item example #1

        # =name
        #
        # Example #1
        #
        # =cut
        #
        # =name
        #
        # Example #2
        #
        # =cut
      
        my $data = Data::Object::Data->new(
          file => 't/examples/content.pod'
        );
      
        $data->item('name');
      
        # {
        #   index => 1,
        #   data => ['Example #1'],
        #   list => undef,
        #   name => 'name'
        # }

 list

      list(Str $name) : ArrayRef

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

    list example #1

        # =name example-1
        #
        # Example #1
        #
        # =cut
        #
        # =name example-2
        #
        # Example #2
        #
        # =cut
      
        my $data = Data::Object::Data->new(
          file => 't/examples/contents.pod'
        );
      
        $data->list('name');
      
        # [{
        #   index => 1,
        #   data => ['Example #1'],
        #   list => 'name',
        #   name => 'example-1'
        # },
        # {
        #   index => 2,
        #   data => ['Example #2'],
        #   list => 'name',
        #   name => 'example-2'
        # }]

 list_item

      list_item(Str $list, Str $item) : ArrayRef[HashRef]

    The list_item method returns metadata for the pod-like sections that
    matches the given list name and argument.

    list_item example #1

        # =name example-1
        #
        # Example #1
        #
        # =cut
        #
        # =name example-2
        #
        # Example #2
        #
        # =cut
      
        my $data = Data::Object::Data->new(
          file => 't/examples/contents.pod'
        );
      
        $data->list_item('name', 'example-2');
      
        # [{
        #   index => 2,
        #   data => ['Example #2'],
        #   list => 'name',
        #   name => 'example-2'
        # }]

 parser

      parser(Str $string) : ArrayRef

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

    parser example #1

        # given: synopsis
      
        $data->parser("=pod\n\nContent\n\n=cut");
      
        # [{
        #   index => 1,
        #   data => ['Content'],
        #   list => undef,
        #   name => 'pod'
        # }]

 pluck

      pluck(Str $type, Str $item) : ArrayRef[HashRef]

    The pluck method splices and returns metadata for the pod-like section
    that matches the given list or item by name. Splicing means that the
    parsed dataset will be reduced each time this method returns data,
    making this useful with iterators and reducers.

    pluck example #1

        # =name example-1
        #
        # Example #1
        #
        # =cut
        #
        # =name example-2
        #
        # Example #2
        #
        # =cut
      
        my $data = Data::Object::Data->new(
          file => 't/examples/contents.pod'
        );
      
        $data->pluck('list', 'name');
      
        # [{
        #   index => 1,
        #   data => ['Example #1'],
        #   list => 'name',
        #   name => 'example-1'
        # },{
        #   index => 2,
        #   data => ['Example #2'],
        #   list => 'name',
        #   name => 'example-2'
        # }]

    pluck example #2

        # =name example-1
        #
        # Example #1
        #
        # =cut
        #
        # =name example-2
        #
        # Example #2
        #
        # =cut
      
        my $data = Data::Object::Data->new(
          file => 't/examples/contents.pod'
        );
      
        $data->pluck('item', 'example-1');
      
        # [{
        #   index => 1,
        #   data => ['Example #1'],
        #   list => 'name',
        #   name => 'example-1'
        # }]
      
        $data->pluck('item', 'example-2');
      
        # [{
        #   index => 2,
        #   data => ['Example #2'],
        #   list => 'name',
        #   name => 'example-2'
        # }]

    pluck example #3

        # =name example-1
        #
        # Example #1
        #
        # =cut
        #
        # =name example-2
        #
        # Example #2
        #
        # =cut
      
        my $data = Data::Object::Data->new(
          file => 't/examples/contents.pod'
        );
      
        $data->pluck('list', 'name');
      
        # [{
        #   index => 1,
        #   data => ['Example #1'],
        #   list => 'name',
        #   name => 'example-1'
        # },{
        #   index => 2,
        #   data => ['Example #2'],
        #   list => 'name',
        #   name => 'example-2'
        # }]
      
        $data->pluck('list', 'name');
      
        # []
