v1.3.0

Support for saving values to JSON files and loading them back.

Change Log

• serialization to JSON:
  • json.save_to_json() function — this function serializes the passed value to the JSON with the json.to_json() function and saves the result to the file at the specified path via the file writer:
    • the default implementation of the file writer uses the standard io package;
  • json.load_from_json() function — this function loads the JSON via the file reader and transforms it to a data with the json.from_json() function:
    • optionally, it can validate the data against a JSON Schema;
    • optionally, it can recreate tables with the __name property with the passed constructors;
    • the default implementation of the file reader uses the standard io package;
  • the json module now supports Lua 5.1;
• project maintenance:
  • added Lua 5.5 to the test matrix and restored standard LuaJIT testing;
  • updated the minimum supported version of the luatypechecks dependency to 1.3.4.

Features

• data.to_data() function — this function recursively calls the __data() metamethod if it exists:
  • supports for enhancing tables with the __name metaproperty;
• Nameable mixin — this mixin adds the __name metaproperty to a class created by library middleclass; this metaproperty equals to the name property of the mix target class;
• serialization to string:
  • string.to_string() function — this function calls the data.to_data() function and then applies library inspect.lua;
  • Stringifiable mixin — this mixin adds the __tostring() metamethod that calls the string.to_string() function;
• serialization to JSON:
  • json.to_json() function — this function calls the data.to_data() function and then transforms the data into the JSON;
  • json.save_to_json() function — this function serializes the passed value to the JSON with the json.to_json() function and saves the result to the file at the specified path via the file writer:
    • the default implementation of the file writer uses the standard io package;
  • json.from_json() function — this function transforms the text in the JSON to a data:
    • optionally, it can validate the data against a JSON Schema;
    • optionally, it can recreate tables with the __name property with the passed constructors;
  • json.load_from_json() function — this function loads the JSON via the file reader and transforms it to a data with the json.from_json() function:
    • optionally, it can validate the data against a JSON Schema;
    • optionally, it can recreate tables with the __name property with the passed constructors;
    • the default implementation of the file reader uses the standard io package.

v1.2.0

Support for table constructors in the json.from_json() function.

    • optionally, it can recreate tables with the __name property with the passed constructors.
