How to precompile code?

[splashsky]

Hey there! Apparently, you can't call functions across different states - but is it possible for me to precompile some Lua code into bytecode that can be executed in any arbitrary state? This is a key feature for what I am attempting to build.

Have you tried Function::dump ?

No, I'm trying to use LuaJIT and need to more or less precompile Lua code into bytecode chunks for reuse. I could make it fit into a function call, but it's not a great candidate for that.

[khvzak]

Any chunk is a function in Lua.

This is an example how to compile any chunk to bytecode:

let bytecode = lua.load("print(123)").into_function()?.dump(false);

And this works for any arbitrary bit of Lua code? i.e. an entire script loaded into a "function" then executed somewhere in the state?
