Is the Programming in Lua, fourth edition e-book not available to libraries?

I have started reading the first edition of Programming in Lua and quite like it. I understand the language has changed at least somewhat since it was written and that the fourth edition has a changed (improved?) layout. I wanted to take a look but I can't find it in the digital catalog of any of my libraries.

Hence the noscript question: Is the Programming in Lua, fourth edition e-book not available to libraries?

How to add type annotations to compiled C module

My lua module is implemented entirely in C. It is not quite yet ready for prime time, but it is close enough to start thinking about how to make it nice.

One of the things I want is luaCats type annotations. But I cant figure out how to add them to my compiled module?

In my rockspec I have these build instructions, which tell it to use my makefile, and set up passthru for the variables I will need as specified by their documentation. The build and main install step work, which require LUA\_INCDIR in build and LIBDIR in install

build = {
type = "make",
build_variables = {
LUA_INCDIR="$(LUA_INCDIR)",
},
install_variables = {
LIBDIR="$(LIBDIR)",
LUADIR="$(LUADIR)",
},
}

And in the makefile in my install step I do

install: $(SRC)/meta.lua
ifdef LIBDIR
$(check_so_was_built)
@mkdir -p "$(LIBDIR)";
cp "$(DESTDIR)/$(MYMODNAME).so" "$(LIBDIR)/";
@echo "Installed to $(LIBDIR)";
ifdef LUADIR
@mkdir -p "$(LUADIR)/$(MYMODNAME)";
cp "$(SRC)/meta.lua" "$(LUADIR)/$(MYMODNAME)/";
endif
else
@echo "LIBDIR not set, skipping install"
endif

The types in my meta.lua are correct enough and work when I am inside the project directory

However when I install my package via luarocks, usually my editor can find the types for the modules I installed. But for this one it cannot find the types declared in my meta.lua file if I try to declare them manually, nor does it associate `tomlua/meta.lua` with `require('tomlua')` as I thought it was meant to? It does seem to successfully get the meta.lua file to where I expect it to go to, but it isnt being picked up by the lsp.

Looking for a Developer / Reverse Engineer
I’m seeking someone with strong experience in C# and LuaJIT (including working with runtime dumps and decompiled bytecode). The task involves analyzing and reversing some files, so familiarity with reverse engineering practices is important.

Is it a good idea to use Lua (with JIT) in some serious applications?

I heard it has simplicity of Python combined with the speed of C-languages. I asked ChatGPT about it and it said they never use it just because people never do.

So, maybe I will be an exception? Because I like metatables and the Lua syntax itself

I've done something with the lua API

I've been learning about Lua, especially how it works, and I understand the stack method it uses to store things. Well, that's more or less what I understood from its documentation. Playing around with the API, I created something with SDL Mixer. It's basic for playing audio files, so I'm just learning. I'd like your feedback and recommendations. Feel free to contribute if you'd like. To the code. https://github.com/JuanPerdomo00/Laudio

blackscreen NUI fix.

FIVEM if you ever built a UI and are bashing your head against the wall with a backscreen that just wont go away here is the fix. Root cause: CEF (the Chromium wrapper FiveM uses) was compositing a fallback opaque layer behind your UI. If the page/body/background aren’t explicitly transparent, or if you use CSS effects that force a new compositing layer (backdrop-filter, heavy box-shadow, large border radii), CEF often draws a solid black rounded rectangle as the fallback.

What the fixes did:

Explicitly set body/html background to transparent so CEF knows to render game beneath the page.

Removed backdrop-filter and reduced/removed the heavy box-shadow so the browser didn’t create the extra opaque compositing layer.a

Used a semi‑transparent RGBA card color instead of relying on filters; that avoids forcing the opaque fallback.

Practical note: If artifacts persist after code changes, clear FiveM cache and restart the client because CEF can cache rendered frames.

What do you think about OOP in Lua?

Hi guys, I recently started to learning Lua, and pretty fast I learn almost everything, but only metatables, the most powerful Lua thing, left (and coroutines btw, but that's not the topic). And, using some meta-functions, you can basically create everything. Also I saw an example when you can create any object of type Person, and setup its parameters, like name, age etc. I don't understand yet what it actually doing to reach this, so I want to ask you: is OOP in Lua that comfortable like, for example, in C++ or Java?

(Luau) I'm having a problem with generating grass.

I am making static generating terrain that was originally from infinitely generating terrain (I got too lazy)

the problem is it's not generating grass no matter what I do. I am trying to return "grassland" back so It generates. I have left you with a lot of comments so you could find out what is what.

Macros / Inline Syntax and Text Replacement

Are there any good LUA transpilers that bring this functionality?

I think having your own syntax sugars would make the language even more powerful and intuitive as is. I'm working on my own solution running on a language server because i haven't found something sensible yet.
