Gedcom::Grammar(3pm)					User Contributed Perl Documentation				      Gedcom::Grammar(3pm)

NAME

       Gedcom::Grammar - a module to manipulate Gedcom grammars

       Version 1.16 - 24th April 2009

SYNOPSIS

	 use Gedcom::Grammar;

	 my $st = $grammar->structure("GEDCOM");
	 my @sgr = $grammar->item("DATE");
	 my @items = $grammar->valid_items;
	 my $min = $grammar->min;
	 my $max = $grammar->max;
	 my @items = $grammar->items;

DESCRIPTION

       A selection of subroutines to handle the grammar of a gedcom file.

       Derived from Gedcom::Item.

HASH MEMBERS

       Some of the more important hash members are:

   $grammar->{top}
       The top of the grammar tree.

   $grammar->{top}{structures}
       A reference to a hash mapping the names of all structures to the grammar objects.

METHODS

   structures
	 my $st = $grammar->structure("GEDCOM");

       Return the grammar item of the specified structure, if it exists, or undef.

   item
	 my @sgr = $grammar->item("DATE");

       Return a list of the possible grammar items of the specified sub-item, if it exists.

   min
	 my $min = $grammar->min;

       Return the minimum permissible number of $grammar items

   max
	 my $max = $grammar->max;

       Return the maximum permissible number of $grammar items

   items
	 my @items = $grammar->items;

       Return a list of tags of the grammar's sub-items

   valid_items
	 my @items = $grammar->valid_items;

       Return a hash detailing all the valid sub-items of the grammar item.  The key is the tag of the sub-item and the value is an array of
       hashes with three members:

	 grammar => the sub-item grammar
	 min	 => the minimum permissible number of these sub-items
	 max	 => the maximum permissible number of these sub-items
