Ware is an embeddable library that allows addons to transfer data into (and out of) restricted environments via Lua's ordinary table syntax, without serialization to Lua code. It also provides a simple mechanism for passing arguments to restricted snippets executed from insecure code.
Usage
You can install Ware as a stand-alone addon (in which case it is accessible via the global _G.Ware), or embed it into your own addon (in which case it is embedded into your private addon table: local _, T = ...; local Ware = T.Ware).
For documentation and examples, see the official site and reference manual.
