NAME

       yapps - create a Python module from a grammar file

SYNOPSIS

       yapps [ --dump ] [ --use-devel-grammar ] [ -fcontext-insensitive-scanner ] [ -p	pid ] [ -f ] input.g [ output.py ]  name

DESCRIPTION

	 --dump 			  Dump out grammar information
	   --use-devel-grammar		     Use the devel grammar parser from	    yapps_grammar.py instead of the stable grammar from grammar.py
	      -fcontext-insensitive-scanner    Scan all tokens (see docs)

       yapps generates a Python program which will parse a given grammar.

OPTIONS

       --dump Dump the grammar information to stdout.

       --use-devel-grammar
	      Use the grammar file in ./yapps_grammar.py instead of yapps/grammar.py.
	      This option is useful for testing new grammar parsers. (Yes, yapps' parser is itself written with yapps...)

       -fcontext-insensitive-scanner
	      Set the option to use the non-context-sensitive scanner.

CAVEATS

       yapps implements a recursive-descent scanner.

HISTORY

       Written by Amit J. Patel <amitp@cs.stanford.edu>.
       This version was enhanced by Matthias Urlichs <smurf@debian.org>.  It is not downwards-compatible with the original yapps2 (yet) and uses a
       different runtime library.
       See the change log for details.

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
