Lua C API tutorial: using the stack and working with tables

This tutorial covers the most fundamental functions of Lua's C API. This will be useful to anyone:
* writing a Lua module that needs to run C code,
* embedding Lua as a scripting language, or
* creating a framework or game engine using Lua.

I don't specifically talk about C++ or Objective-C, but Lua's C API is compatible with those languages as well.

This video also uses an educational module called apidemo. If you have luarocks, you can install this module by running:

sudo luarocks install apidemo

This module is open source; here is the repo for it:

Don't know if you still answer questions on this video since its 3 years old, but I have one nonetheless. At 35 minutes into the video you did a lua=tointeger(L, 2) and got back a 12 from the stack. Does a tointeger not change the value on stack the same as a push? Because right after you did an optnumber and it still returned the value 12.3 even tho you can converted to string and then converted to the number 12? I was just expecting the stack to now contain 12 in the 2 position of the stack and instead it still returned 12.3. Can you enlighten me as to what happened there?

Aw hell yeah, what's your Vim colour scheme? Is it premade or did you write it yourself?
