Lua: Programming For Absolute Beginners

Install Lua on Windows by downloading a binary, choosing 64-bit or 32-bit, extracting files, updating the environment path, and verifying the version in cmd.

Learn to write and run a first Lua program by installing Lua and setting up a project in Visual Studio Code. Create hello world.lua and print 'Hello world'.

Explore the five basic data types in Lua: nil, number, string, boolean, and tables, and understand how each type is defined and used.

Learn to write comments in Lua using two hyphens for single-line comments and, with a selected block, control plus slash for multi-line comments, then run code to print Hello world.

Learn about variables in lua by comparing local and global scope; define a local variable with a value, and a global variable using the underscore g convention.

Learn strings in Lua by declaring local variables, using multi-line literals, and converting numbers with tostring. Apply common string operations such as string.sub, string.byte, string.gsub, string.find, string.match, and string.format.

Learn Lua basics: numbers, string to number conversion with tonumber, and math tools like random, pi, min, max, floor, sin, cos, tan, os.time, and making your own math functions.

Master if-else in Lua by using end and print, with comparisons like >, <, >=, <=, ==, ~= and booleans to control flow.

Explore Lua loops using for with start end and step to print sequences and iterate arrays by length; practice while and repeat loops to control execution.

Explore user input in Lua by reading a numeric answer, converting it with tonumber, and validating it against 10 plus 5 with correct/incorrect feedback.

Explore tables in Lua, the language's arrays, capable of storing numbers, strings, and booleans. Learn indexing from 1, length, sorting, inserting, removing, and iterating with for loops.

Learn to use Lua's os module to get the current date and time, run system commands like ip config, measure execution time with clock, and control program flow with exit.

Explore functions in Lua, learn to create local and anonymous functions, handle default and variable parameters, return multiple values, and use recursion, for loops, and varargs for reusable code.

Explore how Lua interacts with files by creating, writing, and closing, reading the first five characters, numbers, and lines, and using io.open for writing or appending.

Learn how to create custom modules in Lua, define global and local functions, and import them into a separate file using require to perform operations like add and power.

Explore object oriented programming in Lua by mimicking objects with tables and metatables, creating pets with feed and status methods, and illustrating inheritance with Lassie.

Learn how coroutines in Lua enable cooperative multitasking by creating, yielding, and resuming functions; switch between routines, inspect status, and manage suspension and completion.

Learn how to use meta methods in Lua to overload operators on tables by defining a meta table with add and sub functions, and applying them to table values.

Explore luarocks, a lightweight Lua package manager, to download packages and build powerful apps with love for game development. Learn dependency management and installation basics for Lua and C modules.

Consolidate Lua knowledge by reviewing syntax, semantics, control structures, functions, and tables. Explore metatables, coroutines, Lua rocks, and Lua packages for game development and embedded systems.
