JSON::Decode::Regexp - JSON parser as a single Perl Regex
This document describes version 0.101 of JSON::Decode::Regexp (from Perl distribution JSON-Decode-Regexp), released on 2018-03-25.
use JSON::Decode::Regexp qw(from_json); my $data = from_json(q([1, true, "a", {"b":null}]));
This module is a packaging of Randal L. Schwartz' code (with some modification) originally posted at:
http://perlmonks.org/?node_id=995856
The code is licensed "just like Perl".
Decode JSON in $str. Dies on error.
$str
As of version 0.04, performance-wise this module quite on par with JSON::PP (faster on strings and longer arrays/objects, slower on simpler JSON) and a bit slower than JSON::Tiny. And of course all three are much slower than XS-based modules like JSON::XS.
JSON::Decode::Regexp does not yet support Unicode, and does not pinpoint exact location on parse error.
In general, I don't see a point in using it in production (I recommend instead JSON::XS or Cpanel::JSON::XS if you can use XS modules, or JSON::Tiny if you must use pure Perl modules). But it is a cool hack that demonstrates the power of Perl regular expressions and beautiful code.
