Learn LUA with Real Code Examples

Download Lua from https://www.lua.org/

Use package managers: LuaRocks for library management

Compile from source for custom builds

Integrate with host applications via C API

Use Lua interpreters or REPL for testing

Install Lua from lua.org or via package manager

Install LuaRocks for dependency management

Use ZeroBrane Studio or VSCode with Lua extensions

Test scripts with REPL

Optionally build LuaJIT for faster execution

init.lua - main entry script

config.lua - configuration file

module.lua - reusable module

rockspec - LuaRocks package specification

Makefile - optional build automation

lua main.lua - run Lua script

luac -o main.luac main.lua - compile bytecode

luarocks install <package> - install package

lua -i - interactive REPL

luarocks remove <package> - uninstall package

Use tables for language strings

Load localization data at runtime

Handle UTF-8 encoding

Switch languages via config or environment variables

Support multiple locales with minimal code changes

Depends on host application for UI

Provide semantic labels and descriptions

Ensure text and audio feedback if embedded in games

Use tables for structured accessibility data

Test accessibility in target application

Lua itself has no built-in UI

Used in game engines (LOVE2D) for UI elements

UI layout via host application APIs

Animation handled by host or engine

Data-driven styling via tables

Variables are dynamically typed

Tables hold structured data

Coroutines manage cooperative state

Global vs local variables carefully managed

Modules can encapsulate state

Tables as arrays, dictionaries, or objects

JSON encoding/decoding with cjson or dkjson

Use metatables for custom behaviors

Load and save data files for persistence

Embed Lua in host apps to manage application data
