Lua is one of the greatest scripting language for video game mods that I have encountered. If you're creating a game and have mods in mind as a possible feature, include Lua scripts in that mod loader, the community will make amazing things with it.

that's a good way of saying its very easy to use!
Lua doesn't have Regex because the Regex C library is bigger than the entire Lua compiler and runtime, including Lua's own "Lua patterns" that works like a simpler Regex.
I love lua patterns soo much!
or you can write your own parser, which, let's face it, is probably gonna be smaller than the regex matcher
Some CS:GO cheats' Lua API's have an ability to run JavaScript code, so we just use that if Lua patterns limit us lol

While there are no traditional classes in lua, you should note that there is a concept called metatables that allows for object oriented programming.

Lua is interesting because it's what I'd a call a "low level" scripting langauge. It's not close to the metal or anything, but it is quite flexible. It doesn't have classes, but you can implement them with function tables, metatables, or closures, each having its advantages and disadvantages. You can also implement multiple inheritance using metatable pooling. You can reuse tables to conserve memory with the table.clear() function. Iterators are simply functions that return a function for retrieving the next element of your (custom) collection.
No one cares.

So glad I came across this language a while ago, becuase of this video! I like the extreme portability and simplicity. Making games and desktop apps (that don't need to be super secure, or don't need to cummunicate with a lot of outside devices (printers, routers etc.)) with this language is pretty painless and straight foreward.
To me, Lua always felt like someone heard the "JavaScript the Good Parts" talk by Doug Crockford, and decided to make a language from it. Sometimes I wish, we had Lua in the browser.
Computercraft is a populair Minecraft mod that adds programmable blocks and drones (turtles) into the game, it uses Lua as their scripting language and it's how I got in contact with programming for the first time.

Lua does have classes (though it doesn't do them the same way python for example does), they can be created via a metatable and they support inheritance, object values, the self keyword and just about anything else you can think of.
Thanks to the colon operator closely followed by the self keyword, it's obviously an intended feature rather than something that can be simulated.
Actually self is not a keyword but a default defined argument of functions that use the colon notation instead of dot
Lua doesn't have classes, but you can make classes using table.
if lua had classes then there would be a class keyword of something of that sort
@@elpersonpl576 they can have class keyword and still doesn't have classes, if the class keyword is just syntactic sugar.
@@mikumikudice It's pretty much what I meant since I added it right after that point, not to mention that self in Lua cannot be used outside of a function with colon notation, but regardless thank you for the correction.
This video helped me understand Tables a bit beter, thanks Fireship!
It would be appreciable if you can make full length Lua programming series or suggest some best tutorials for this language.😊
I agree it's greatly underrated. Its flexibility is amazing. I've hopped around through many languages over the past 15 years, never really feeling comfortable about any. I tried Lua some 4 years ago, and at first I struggled a bit with the 1-indexing, but it didn't take long for me to really settle for it. Coding in Lua is a breeze. I only stopped for about a year because I thought it wasn't fast enough for my gaming projects, but eventually I went back and I found out it was just my bad implementation being bad.
Lua, at least with LOVE/LuaJIT, is actually really fast.
Lua being a simple language is also a plus. When I got back to it after that long pause, I still remembered almost everything about it. And it's also the one language I can go for days or even weeks without needing to check something in its documentation.
Wow bro thanks for information
man lua is so fucking fast. learning to work around the JIT's nuance + storing data in c types will give you ungodly performance you would not believe. People really dont understand how fast this language can get. Those benchmarks showing near C and sometimes faster than C speeds are real.
I agree on lua's flexibility and simplicity, in lua everything just feels really straight forward, i feel like my only limit is the speed of my hands and the language is fast, where as in other languages i feel like i have to do roundabout techniques to get what i want, also lua's first class functions are a huge plus, its painful for me to use a language without first class functions at this point.
Edit: also tables and metatables really deserve more credit, they can do the job of what in other languages you'd have like 4+ things to do it, for example tables can function as: arrays, dictionaries, structs, enums, etc.. and if you learn metatables (easier than they seem) you can emulate classes if you really wanted to, but because of how unbelievably flexible lua ls you wont even feel like you need to, its honestly really sad how it stagnated
I also love lua for how common it is in sandbox games
Be it Roblox (how I discovered it), Gmod, ComputerCraft, you name it. Its quite common in that niche.
First time I heard about lua when I thought about switching vscode by nvim and found out plenty of nvim plugins are written in lua. That was a barrier for me 'cause I really didn't want to spend a lot of time learing new language just to use nvim properly. But just this one small video makes me feel it's not that scary to go into lua. Thank you Jeff for your videos they're really inspiring

Lua is most probably the easiest language to get into
I know this comment it a year old, but for others: You will literally learn Lua naturally without even trying just by taking the time to configure neovim how you like it. Assuming you have some very minimal programming experience in any language, you can just dive in, you will figure it out as you go without once ever reading the Lua docs.
I was looking for a language to start learning coding and this looks perfect!
This is the greatest video ever, now I know a lot more about Lua than I already did :0
You can define dictionary tables without the `["index"]` syntax. That is only required for using non-standard names (like ones containing special characters) or when the key you want to assign something to is dynamic (for example, you want to assign specific keys from a loop, but you don't know the key name at that point). This syntax works as well (and from what I understand, seems to be the convention): `local t = { x = 4, y = 2 }`. You can also access table fields both using `varname["key"]` and a more "object"-asque syntax with `varname.key`.
Exactly. Roblox even _encourages_ using object-style syntax with tables (if the key is a valid variable name, just alphanumerics and no spaces, you're golden for nesting keys as far as you want, and in fact that's literally how accessing game objects in the DataModel natively works, they're functionally just tables inside tables). I got quite good at scripting back when I was still interested in the game, and even made a few ModuleScripts (libraries) for referencing Terrain voxels (which natively have to be accessed using stud coordinates for some reason???) using more reasonable "one voxel, one index over" coordinates, aka how Minecraft and literally all other voxel engines read and write their data structures...
Just like Javascript

Is there a downside to doing that?

It was my first language to deal with, I modded so much things on old Gmod servers in Lua, most of the CS:S and OrangeBox games (based on Source 1 before the BIG source 1 update that killed 120 tick servers...) used Lua to give the community the ability to create plugins ! Loved this one Jeff, thanks for the memories :)
My first encounter with Lua was on roblox, I was probably only 9 or 10 at the time but even at that age I was able to grasp the absolute basics, that's how simple Lua is. A few years after that I attempted to get into minecraft modding, but the absurd amount of work required to just do anything in Java immediately made me gave up because it was so much more fun to use Lua and especially roblox's engine which basically makes the barrier of entry to being a gamedev absolutely non-existent.

Ugh, now I'm getting docked hipster points for my preferred language being covered on this channel! ;)
Understandable omitting the use of metamethods & metatables given the 100 second overview, but they are a very powerful concept that allow you to (amongst other things) write in an object-oriented manner also. Definitely worthwhile exploring for any folks interested in picking up Lua
I've heard of Lua once when I was in college, didn't think too much of it.
Watching this video has piqued my interest again -- insanely awesome!
I think it's incredibly powerful, that Lua has a C API that allows developers to run Lua code in a C program, and vice versa.
Great -- how am I suppose to get my work for the day done now? 😂
This happpens to me every single time I discover something new 🤣
I also thought Lua was just a meme. But a lightweight interpreted language sounds very interesting...
But be aware that although the "run Lua code in a C Program" part is very easy to do, the "run C program in lua code" will require a lot of binding work.
about running C inside an interpreted language is nothing new really, most language has support to it, Ruby for example has a lot of libs(gems) that uses C to speed up the code
@@victor95pc It's called FFI (foreign function interface). This technology is present in all jit (just in time) compilers of various languages (see JNA for Java or cffi in python/pypy). It binds at runtime instead of compile-time so calling bound functions is a bit slower.

I knew next to nothing about lua except for the array indexing weirdness, and now I have a much better grasp of the 'Lua Philosophy' now.
Thanks Mr. Ship!
I suppose it's worth noting that you can in practice use tables with zero indexing, with the caveat that you compensate for it in *for* loops (e.g. subtract 1 from the limit, as in *for i=0, width-1 do)* and keep in mind you shouldn't rely on *#* to get the length of that table, because *#* doesn't take the index 0 into account (or else keep in mind the length of the table will be *#table** + 1).* This is usually not a problem, though. When I started out in Lua I found it a bit confusing to know when I should use 1 and when I could safely use 0, but it didn't take much time to get it figured out.
LUA was really fun to learn when I was making WoW mods. It became a meme at my company where I would suggest we rewrite the front end of our entire application library in LUA at almost every standup meeting ha

Coincidentally it's a Brazilian language too!

Its underrated because Google chose Python, and a lot of really important libraries followed suit.

@@Pyrohawk I mean its just true. The only thing Lua is really missing is more popular libraries. If it had that it'd be a solid competitor to Python.
@@iamunamed5800 LUA is intended to be a simplest-but-functional scripting language to be added to your C program. It is not self-sufficient by design. LUA must drop this simplicity principle to be able to become self-sufficient and be able to compete with python. It will effectively prevent LUA being LUA.
I used lua for my game's scripting language (the engine is written in C++) and it made letting other less coder devs get involved in the coding and make useful functions without having to understand the nasty engine stuff. It has been great. I really love how simple it is while retaining a c-like syntax. My only complaint is that it indexes at 1, only thing I'd really want to change about it is make it index at 0, like every other normal language. Everything else is pretty intuitive and sensible. Would highly recommend using it as a scripting language for a game, but don't have much experience using it for other things.
Lua is way cooler than I thought though, been wanting to learn it for a while.
I'd also add that lua has proper tail call recursion, so you can use functional paradigms without bloating your stack (yes I'm looking at you python) - and this was before funcional programming was hip.

That array index starting at '1' reaction was hilarious. 🤣 1:32
Lua é a linguagem mais fácil de aprender :)
Nunca pensei que ia ter um video sobre a linguagem lua aqui
Lua is a sick language and I'm glad it got covered here. Check out it's sister languages: moonscript, teal, pallene, Titan and Fennel
there's also 'shine'
I've only ever used Lua for ROBLOX and Garry's Mod scripting, but it seems interesting. Great video!
i love Lua so much
First introduction to Lua for me was World of Warcraft modding, but nowadays I use it only for programming stuff in modded Minecraft (CCTweaked, OpenComputers). Oh how I despise meta tables though. I've been doing OOP for so long that my brain is wired to think in classes. It's a neat language though, as long as you're open to think a bit differently.
'dynamic language' and 'no type annotations are required' are two different things. You can write a C++ program always using auto etc. but it still isn't dynamically typed.
but auto still is type annotation, no?
Popular programs that uses Lua in some way:
- AwesomeWM (Window Manager)
- Neovim (text editor)
- Wezterm (terminal emulator)
Using lua for modding games is ducking amazing
Fun fact, you can put functions within tables to mimic classes, you can even use a special metatable keyword in a for loop to create new copies of the class.
All my years of programming games in Defold are paying off 😂
