NAME

Catmandu::Fix::marc_paste - paste a MARC structured field back into the MARC record

SYNOPSIS

    # Copy and paste to the end of the record
    marc_copy(001, fixed001)
    set_fieldfixed001.$first.tag,002)
    marc_paste(fixed001)

    # Copy and paste in place (rename a field)
    do marc_each(var:this)
      if all_match(this.tag,001)
        # Change it
        set_field(this.tag,002)

        # Paste it back into the record
        marc_paste(this)
      end
    end

DESCRIPTION

Paste a MARC stucture created by Catmandu::Fix::marc_struc back at the end of a MARC record.

METHODS

marc_paste(JSON_PATH, [at: MARC_PATH , [equals: REGEX]])

Paste a MARC struct PATH back in the MARC record. By default the MARC structure will be pasted at the end of the record. Optionally provide an at option to set the MARC field after which the structure needs to be pasted. Optionally provide a regex that should match the content of the at field.

The equals parameter requires an at parameter. When both are provided, then the value of JSON_PATH will only be pasted if the string value of the MARC_PATH in at matches the regular expression equals.

    # Paste mycopy at the end of the record
    marc_paste(mycopy)

    # Paste mycopy after the last 300 field
    marc_paste(mycopy, at:300)

    # Paste mycopy after the last 300 field with indicator1 = 1
    marc_paste(mycopy, at:300[1])

    # Paste mycopy after the last 300 field which has an 'a' subfield
    marc_paste(mycopy, at:300a)

    # Paste mycopy after the last 300 field which has an 'a' subfield equal to 'ABC'
    marc_paste(mycopy, at:300a, equals:'^ABC$')

    # Paste mycopy after the last 300 field with all concatinated subfields equal to 'ABC'
    marc_paste(mycopy, at:300, equals:'^ABC$')

INLINE

This Fix can be used inline in a Perl script:

    use Catmandu::Fix::marc_copy as => 'marc_copy';
    use Catmandu::Fix::marc_paste as => 'marc_paste';

    my $data = { record => ['650', ' ', 0, 'a', 'Perl'] };

    $data = marc_copy($data,'650','subject');
    $data = marc_paste($data,'subject');
