NAME
    Data::Clean::JSON - Clean data so it is safe to output to JSON

VERSION
    version 0.01

SYNOPSIS
     use Data::Clean::JSON;
     my $cleaner = Data::Clean::JSON->new;    # there are some options
     my $data    = { code=>sub {}, re=>qr/abc/i };

     my $cleaned;

     # modifies data in-place
     $cleaned = $cleaner->clean($data);

     # ditto, but deep clone first, return
     $cleaned = $cleaner->clone_and_clean($data);

     # now output it
     use JSON;
     print encode_json($cleaned); # prints '{"code":"CODE","re":"(?^i:abc)"}'

DESCRIPTION
    This class cleans data from anything that might be problematic when
    encoding to JSON. This includes coderefs, globs, and so on.

    Data that has been cleaned will probably not be convertible back to the
    original, due to information loss (for example, coderefs converted to
    string "CODE").

    The design goals are good performance, good defaults, and just enough
    flexibility. The original use-case is for returning JSON response in
    HTTP API service.

METHODS
  new(%opts) => $obj
    Create a new instance. For list of known options, see Data::Clean::Base.
    Data::Clean::JSON sets the following options:

     (
         CODE     => [str => "CODE"],   # convert coderef to string "CODE"
         DateTime => [str => 'epoch'],  # convert DateTime object to Unix time
         Regexp   => ['str'],           # stringify Regexp
     )

  $obj->clean_in_place($data) => $cleaned
    Clean $data. Modify data in-place.

  $obj->clone_and_clean($data) => $cleaned
    Clean $data. Clone $data first.
