    Thanks, that looks like what I should be doing all right.

    But doing this:

    use JSON;
my $j = JSON->new();
$j->boolean_values( 1, 0 );

    Gets me Can't locate object method "boolean_values" via package "JSON"

    What am I doing wrong?

      Hello Cody Fendant

      grepping CPAN it seems the method ships with JSON::PP and you can read about it

      # Note that JSON version 2.0 and above will automatically use
# JSON::XS or JSON::PP, so you should be able to just:
 
use JSON;

      This probably means you have also JSON::XS installed and it is loaded first

        Both JSON::PP and JSON::XS support boolean_values, and the error message said the method wasn't found in JSON, not JSON::XS.

      works fine for me, JSON v4.03, JSON::PP v4.06

      Are you using version 4+?

        I was using the very latest JSON, but not the very latest JSON::PP, so that's a factor. Upgrading JSON::PP and specifically using that has fixed it.
