Show HN: Ldump – serialize any Lua data

girvel Friday, January 31, 2025

Some time ago, I was implementing saves for my LOVE2D game. I wanted to do a full dump of the game state -- which included closures (AI), complex graphs, sets with tables as keys and also fundamentally non-serializable data (coroutines and userdata), that require user-defined serialization/deserialization logic. I went through every Lua serialization library -- none covered all data types/cases. So I wrote my own.

It is a polished version, thoroughly annotated, tested and documented. It is made to be as functional and customizable as possible (or at least I did everything I could think of). I would be happy to hear suggestions/corrections for both code and documentation -- even nitpicky ones.

Summary
The article discusses the development of ldump, a lightweight command-line utility for creating and managing database backups. It emphasizes the tool's simplicity, ease of use, and the ability to perform incremental backups, making it a versatile solution for managing database backups.
