NAME
JSON::MaybeXS - use Cpanel::JSON::XS with a fallback to JSON::PP
SYNOPSIS
use JSON::MaybeXS;
my $data_structure = decode_json($json_input);
my $json_output = encode_json($data_structure);
my $json = JSON->new;
DESCRIPTION
This module tries to load Cpanel::JSON::XS, and if that fails instead
tries to load JSON::PP. If neither is available, an exception will be
thrown.
It then exports the "encode_json" and "decode_json" functions from the
loaded module, along with a "JSON" constant that returns the class name
for calling "new" on.
EXPORTS
All of "encode_json", "decode_json" and "JSON" are exported by default.
To import only some symbols, specify them on the "use" line:
use JSON::MaybeXS qw(encode_json decode_json); # functions only
use JSON::MaybeXS qw(JSON); # JSON constant only
encode_json
This is the "encode_json" function provided by the selected
implementation module, and takes a perl data stucture which is
serialised to JSON text.
my $json_text = encode_json($data_structure);
decode_json
This is the "decode_json" function provided by the selected
implementation module, and takes a string of JSON text to deserialise to
a perl data structure.
my $data_structure = decode_json($json_text);
JSON
The "JSON" constant returns the selected implementation module's name
for use as a class name - so:
my $json_obj = JSON->new; # returns a Cpanel::JSON::XS or JSON::PP object
and that object can then be used normally:
my $data_structure = $json_obj->decode($json_text); # etc.
