Read JSON into a Perl variable

JSONParse is a module for parsing JSON. JSON means “JavaScript Object Notation” and it is specified in “RFC 7159”.

JSONParse offers the function “parse_json”, which takes a string containing JSON, and returns an equivalent Perl structure. It also offers validation of JSON via “valid_json”, which returns true or false depending on whether the JSON is correct or not, and “assert_valid_json”, which produces a descriptive fatal error if the JSON is invalid. A function “json_file_to_perl” reads JSON from a file, and there is a safer version of “parse_json” called “parse_json_safe” which doesn’t throw exceptions.

For special cases of parsing, there are also methods “new” and “run”, which create a JSON parsing object and run it on text. See “METHODS”.

JSONParse accepts only UTF-8 as input. See “UTF-8 only” and “Handling of Unicode”.
