lua

Embedded Lua 5.4 execution backed by Rust mlua with vendored Lua sources. The module is a cdylib installed as stdlib/lua.so; it does not require a system Lua installation.

Requires: a Rust toolchain (cargo). Build it with make cargo or make buildLynxer.

global setup(){ import("lua"); }

global main(){
    println(global.lua.luaVersion());
    println(global.lua.evalLua("1 + 2 * 3"));
    println(global.lua.runLua("print('hello from Lua')"));
}

Function	Description
`runLua(code)`	Execute an in-memory Lua script and return captured `print` output.
`runLuaFile(path)`	Read and execute a Lua file and return captured `print` output.
`evalLua(expression)`	Evaluate one Lua expression and return its scalar text representation.
`luaVersion()`	Return `Lua 5.4`.
`luaExists()`	Return `true` when the embedded runtime is available.

Lua print arguments are joined with tabs. Each captured output string ends with a newline when the script printed at least one line. Runtime and file errors are returned as strings beginning with Error[syntax]:, Error[runtime]:, Error[io]:, or Error[other]:. The original mlua diagnostic, including the Lua traceback for runtime failures, follows the classification prefix.
