Debugger.lua
06/01/21 07:30 Filed in: Lua
I've spent a fair amount of time looking at the debug library in Lua. It's too much work to write my own debugger using it. (I'd have to debug the debugger.) There is an alternate solution that someone created known as debugger.lua.

More on Debugging
05/18/21 07:33 Filed in: Lua
Last time I started looking into how to debug Lua code and discovered it's really a form of introspection and doesn't feel, to me, like true debugging. Today, I'll continue looking at this capability. Read More…

I'm using Lua in various ways. I'm playing around with an environment, Codea, and need a way to debug my code. Today, I try to find an answer that works in Lua. Read More…
Lua Modules

Lua modules are reusable code. The interesting thing about Lua modules is that like every other thing in the language a module is a Lua table. Today I create and use my own simple module. Read More…
Closures and Injecting Source Code
04/06/21 08:25 Filed in: Lua
I needed a way to change what a Lua program does by letting a user write their own code. I spent yesterday working out how to do this. The solution comes down to closures and injecting source code. Read More…

The Global Table, _G
03/09/21 09:02 Filed in: Lua
Everything in Lua is a table, including variables. Variables that you don't explicitly label as local, are placed into a table known as _G. Today, I learn a bit about how to work with it.

Objects In Lua
02/23/21 08:08 Filed in: Lua
Today, I want to learn about OOP in Lua. Why OOP instead of functional programming? Because I still use OOP in many other languages and want to see how Lua handles it. Let's dive in. Read More…

Welcome to Learning Lua
01/09/21 09:23 Filed in: Lua
Welcome to my Lua learning journey. I was originally going to include learning Lua as part of my getting up to speed on PICO-8, but I knew PICO-8 uses a subset of Lua and didn't want to conflate or confuse the two. I've decided to break Lua out separately. Read More…
