Update of /cvsroot/koha/koha/marc
In directory usw-pr-cvs1:/tmp/cvs-serv22490

Modified Files:
	fill_usmarc.pl marcschema.sql 
Added Files:
	File.pm USMARC.pm 
Log Message:
1st scripts for MARC-DB. 

WARNING : YOU MUST DO THE FOLLOWING IF YOU EXPECT THE MAIN-BRANCH TO WORK.

* install MARC::Record package, from cpan or sourceforge
* OVERWRITE File.pm and USMARC.pm. The original misses 1 functionnality we absolutly need in koha (reading a MARC from a variable, not from a file). Thanks to Steve, who modified MARC::Record.
* modify your DB by adding marcschema.sql tables
* populate new tables by launching fill_usmarc.pl

Then, it should work...
What works exactly will come in the next commit, in a few minuts (hitchcock suspens...)

package MARC::File;

=head1 NAME

MARC::File - Base class for files of MARC records

=cut

use 5.6.0;
use strict;
use integer;
use vars qw( $VERSION $ERROR );

=head1 VERSION

Version 0.93

    $Id: File.pm,v 1.1 2002/07/24 15:52:53 tipaul Exp $

=cut

our $VERSION = '0.93';

=head1 SYNOPSIS

    use MARC::File::USMARC;

    my $file = MARC::File::USMARC->in( $filename );
    
    while ( my $marc = $file->next() ) {
	# Do something
    }
    $file->close();
    undef $file;

=head1 EXPORT

None.  

=head1 METHODS

=head2 in()

Opens a file for input.

=cut

sub in {
    my $class = shift;
    my $filename = shift;

    my $self = {
	filename => $filename,
    };

    bless $self, $class;

    if ( !open( $self->{fh}, "<", $filename ) ) {
	undef $self;
	$MARC::File::ERROR = "Couldn't open $filename: $!";
    }

    return $self;
} # new()

#    }

    return $self;
} # new()

sub out {
    die "Not yet written";
}

=head2 next()

Reads the next record from the file handle passed in.

=cut

sub next {
    my $self = shift;

    my $rec = $self->_next();

    return $rec ? $self->decode($rec) : undef;
}

=head2 skip

Skips over the next record in the file.  Same as C<next()>,
without the overhead of parsing a record you're going to throw away
anyway.

Returns 1 or undef.

=cut

sub skip {
    my $self = shift;

    my $rec = $self->_next();

    return $rec ? 1 : undef;
}

sub close {
    my $self = shift;

    close( $self->{fh} );
    delete $self->{fh};

    return;
}

sub _unimplemented() {
    my $self = shift;
    my $method = shift;

    warn "Method $method must be overridden";
}

sub write   { $_[0]->_unimplemented("write"); }
sub decode  { $_[0]->_unimplemented("decode"); }

# NOTE: _gripe can be called as an object method, or not.  Your choice.
sub _gripe(@) {
    if ( @_ ) {
	shift if ref($_[0]) =~ /^MARC::File/;	# Skip first parm if it's a $self

Constructor for handling data from a USMARC file.  This function takes care of all

=head2 update_leader()

If any changes get made to the MARC record, the first 5 bytes of the
leader (the length) will be invalid.  This function updates the 
leader with the correct length of the record as it would be if
written out to a file.

=cut

=head2 _build_tag_directory()

Function for internal use only: Builds the tag directory that gets
put in front of the data in a MARC record.

Returns two array references, and two lengths: The tag directory, and the data fields themselves,
the length of all data (including the Leader that we expect will be added),
and the size of the Leader and tag directory.

=cut

		my $direntry = sprintf( "%03d%04d%05d", $field->tag, $len, $dataend );
		push( @directory, $direntry );
		$dataend += $len;
	}

		LEADER_LEN +    # better be 24

				# all the directory entries

		$baseaddress +	# stuff before first field
		$dataend + 	# Length of the fields
		1;		# End-of-record marker



	return (\@fields, \@directory, $total, $baseaddress);
}

=head2 encode()

Returns a string of characters suitable for writing out to a USMARC file,
including the leader, directory and all the fields.

=cut

sub encode() {
    my $marc = shift;
    $marc = shift if (ref($marc)||$marc) =~ /^MARC::File/;

  #  
  #  $Log$
+ #  Revision 1.15  2002/07/24 15:52:53  tipaul
+ #  1st scripts for MARC-DB.
+ #
+ #  WARNING : YOU MUST DO THE FOLLOWING IF YOU EXPECT THE MAIN-BRANCH TO WORK.
+ #
+ #  * install MARC::Record package, from cpan or sourceforge
+ #  * OVERWRITE File.pm and USMARC.pm. The original misses 1 functionnality we absolutly need in koha (reading a MARC from a variable, not from a file). Thanks to Steve, who modified MARC::Record.
+ #  * modify your DB by adding marcschema.sql tables
+ #  * populate new tables by launching fill_usmarc.pl
+ #
+ #  Then, it should work...
+ #  What works exactly will come in the next commit, in a few minuts (hitchcock suspens...)
+ #
  #  Revision 1.14  2002/06/04 08:13:31  tipaul
  #  ouuppsss... forget the 1.13 version, i made a mistake. This version works and should be the last
