NAME JSON::Decode::Marpa - JSON parser using Marpa VERSION This document describes version 0.02 of JSON::Decode::Marpa (from Perl distribution JSON-Decode-Marpa), released on 2014-08-27. SYNOPSIS use JSON::Decode::Marpa qw(from_json); my $data = from_json(q([1, true, "a", {"b":null}])); DESCRIPTION This module is based on MarpaX::Demo::JSONParser (using "json.2.bnf"), but offers a more convenient interface for JSON decoding. I packaged this for casual benchmarking against Pegex::JSON and JSON::Decode::Regexp. The result on my computer: Pegex::JSON and JSON::Decode::Marpa are roughly the same speed (but Pegex has a much smaller startup overhead than Marpa). JSON::Decode::Regexp is about an order of magnitude faster than this module, and JSON::XS is about *three orders of magnitude* faster. So that's that. This is the benchmark code used: use 5.010; use strict; use warnings; use Benchmark qw(timethese); use JSON::Decode::Marpa (); use JSON::Decode::Regexp (); use JSON::XS (); use Pegex::JSON; my $json = q([1,"abc\ndef",-2.3,null,[],[1,2,3],{},{"a":1,"b":2}]); my $pgx = Pegex::JSON->new; timethese -0.5, { pegex => sub { $pgx->load($json) }, regexp => sub { JSON::Decode::Regexp::from_json($json) }, marpa => sub { JSON::Decode::Marpa::from_json($json) }, xs => sub { JSON::XS::decode_json($json) }, }; FUNCTIONS from_json($str) => DATA Decode JSON in $str. Dies on error. FAQ SEE ALSO JSON, JSON::PP, JSON::XS, JSON::Tiny, JSON::Decode::Regexp, Pegex::JSON. HOMEPAGE Please visit the project's homepage at . SOURCE Source repository is at .
