NAME
Catmandu::Fix::perlcode - execute Perl code as fix function
DESCRIPTION
Use this fix in the Catmandu fix language to make use of a Perl script:
perlcode(myscript.pl)The script (here myscript.pl) must return a code reference:
sub {
my $data = shift;
$data->{testing} = 1 ; # modify the item
return $data; # and return the data
}When not using the fix language this
my $fixer = Catmandu::Fix->new( fixes => [ do 'myscript.pl' ] );
$fixer->fix( $item );is roughly equivalent to:
my $code = do 'myscript.pl';
$item = $code->( $item )All scripts are cached based on their filename, so using this fix multiple times will only load each given script once.
The code reference gets passed a second value to reject selected items such as possible with see Catmandu::Fix::reject:
sub {
my ($data, $reject) = @_;
if ($data->{my_field} eq 'OK') {
return $data; # return the data and continue processing
}
else {
return $reject; # return the reject flag to ignore this record
}
}
