JSON metadata logger and analyzer written in Lua for the Luvit framework.

Initially written for logging Discord WebSocket payloads, but can be used for any dkjson-compatible data.

Work-in-progress.

• Initialize a JSONLog object with a log name as its only argument.
• Add a key, value pair to the log with JSONLog:add(k, v)
• To cache the log's state for future use, call JSONLog:dumpState(). The filename <name>_state.json is used.
• To output a human-readable analysis of the logged JSON, call JSONLog:dumpPretty(). The filename <name>_pretty.txt is used.
• Optionally call JSONLog:startLoop(ms) to initilize a loop that periodically calls JSONLog:dumpState() and JSONLog:dumpPretty()
• Optionally call JSONLog:stopLoop() to stop the dump loop.
