![]() ![]() Data Structure & Algorithm-Self Paced(C++/JAVA).Full Stack Development with React & Node JS (Live).Data Structure & Algorithm Classes (Live).If $enable is false (the default), then decode will only accept valid JSON texts. I suggest only to use this option to parse application-specific files written by humans (configuration files, resource files etc.) Be aware that this option makes you accept invalid JSON texts as if they were valid!. If $enable is true (or missing), then decode will accept some extensions to normal JSON syntax (see below). The mutators for flags all return the JSON::PP object again and thus calls can be chained: my $json = JSON::PP->new->utf8->space_after->encode( relaxed $json = $json->relaxed() All boolean flags described below are by default disabled (with the exception of allow_nonref, which defaults to enabled since version 4.0). new $json = JSON::PP->newĬreates a new JSON::PP object that can be used to de/encode JSON strings. The object oriented interface lets you configure your own encoding or decoding style, within the limits of supported formats. This section is also taken from JSON::XS. See MAPPING, below, for more information on how JSON values are mapped to Perl. On perl 5.36 and above, will also return true when given one of perl's standard boolean values, such as the result of a comparison. Returns true if the passed scalar represents either JSON::PP::true or JSON::PP::false, two constants that act like 1 and 0 respectively and are also used to represent JSON true and false in Perl strings. JSON::PP::is_bool $is_boolean = JSON::PP::is_bool($scalar) This function call is functionally identical to: $perl_scalar = JSON::PP->new->utf8->decode($json_text)Įxcept being faster. The opposite of encode_json: expects an UTF-8 (binary) string and tries to parse that as an UTF-8 encoded JSON text, returning the resulting reference. decode_json $perl_scalar = decode_json $json_text This function call is functionally identical to: $json_text = JSON::PP->new->utf8->encode($perl_scalar)Įxcept being faster. encode_json $json_text = encode_json $perl_scalarĬonverts the given Perl data structure to a UTF-8 encoded, binary string (that is, the string contains octets only). encode_json and decode_json are exported by default. This section is taken from JSON::XS almost verbatim. JSON::PP has been in the Perl core since Perl 5.14, mainly for CPAN toolchain modules to parse META.json. If you need JavaScript-friendly RFC7159-compliant pure perl module, try JSON::Tiny, which is derived from Mojolicious web framework and is also smaller and faster than JSON::PP. not to escape extra characters such as U+2028 and U+2029, etc), in order for you not to lose such JavaScript-friendliness silently when you use JSON.pm and install JSON::XS for speed or by accident. JSON::PP works as a fallback module when you use JSON module without having installed JSON::XS.īecause of this fallback feature of JSON.pm, JSON::PP tries not to be more JavaScript-friendly than JSON::XS (i.e. JSON::PP is a pure perl JSON decoder/encoder, and (almost) compatible to much faster JSON::XS written by Marc Lehmann in C. # JSON::XS or JSON::PP, so you should be able to just: # Note that JSON version 2.0 and above will automatically use ![]() ![]() $pretty_printed_json_text = $json->encode( $perl_scalar ) $json = JSON::PP->new->ascii->pretty->allow_nonref $perl_hash_or_arrayref = decode_json $utf8_encoded_json_text $utf8_encoded_json_text = encode_json $perl_hash_or_arrayref # exported functions, they croak on error JSON::PP - JSON::XS compatible pure-Perl module. ![]()
