cloudwu / lua-conf

Convert a lua table to a C object , and share it among many lua states .

What's the lua-conf

lua-conf is a lua library , it can convert a lua table to a constant C object (a lightuserdata). And then you can share it among many lua states .

Why use lua-conf

1. Reading the constant C object is thread safe , so you can use it in many lua states concurrently.
2. If you convert a large lua table , it will reduce the memory usage of lua vm . So the garbage collector will run faster (mark less gc objects).
3. Sometimes you need reload the lua vm , the constant data in the table don't need parser again.

Supported types

The keys must be a 32 bit integer or a string, the values can be boolean, string, number, and table.
