NAME¶
Catmandu::Fix::perlcode - execute Perl code as fix functionDESCRIPTION¶
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; ... return $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, $reject) = @_; return rejection_criteria($data) ? $reject : $data; }
To indicate the end processing, return "undef".
