Require lua script from rust

[hgftrdw45ud67is8o89]

I want to know how to require("aluascript") inside rust.

From the readme, it seems like the reverse* is possible. from lua calling rust code as a module.

The reason I want to allow custom scripting as per execution by user.
Is to let rust app always require that lua script and user can edit using lua.

Any help is very useful.

Given an MLua instance lua and that you want to load Lua module module.spec, something like this should do it:

let spec: LuaString = lua.create_string("module.spec")?;
let require: LuaFunction = lua.globals().get("require")?;
let my_module: LuaTable = require.call::<LuaTable>(spec)?;

Obviously this presumes the Lua module you are loading returns a table. You may need to adjust that if it returns a function or other value type.

I see.so then I can do something like

a original lua code
-- a module named 'mymodule.lua'

local my_module= require("mymodule")
my_module.someFunction()

to

let spec: LuaString = lua.create_string("mymodule")?; let require: LuaFunction = lua.globals().get("require")?; let my_module: LuaTable = require.call::<LuaTable>(spec)?; my_module.someFunction()

let me try it,

Not quite. You have to keep going in Rust syntax not Lua. At the end of that sequence my_module will be of type LuaTable on the Rust side. You can call functions in that table, but you're going to need to first .get() them (just like I did to get the require() function out of Lua and bring it over to a Rust handle I can .call(). That or you need to use the method call functions on the LuaTable type.
