Some time ago I wanted to contribute to an open source program. For this I had to learn LUA. I really started to love it for it being so simple yet so powerful.

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.

The way you depict the arrays starting at one is perfection.

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.

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.

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.

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.

This video helped me understand Tables a bit beter, thanks Fireship!

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.

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.

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`.

@WackoMcGoose

2 жыл бұрын

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...

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.

I've only ever used Lua for ROBLOX and Garry's Mod scripting, but it seems interesting. Great video!

My first exposure to programming was through lua and love2d game development. It was a great experience. I am loving programming from then. I would recommend anyone starting programming to give lua a try.

Funnily enough I learned Lua when I was an admin on a Wikia (now Fandom) site. Did some cool stuff with it, like parsing a bespoke record format I created to draw tables, which is nigh impossible with wiki markup. Things went sideways and I left but the things I learned on the Mediawiki environment I'd always cherish. Lua being the scripting language of choice of many programs like VLC and Garry's Mod makes it easy for me to dip my toes into them too, as I approach them as a returning Lua coder instead.

@@_mickmccarthy That's actually how I got started with Lua, yeah

Thank you so much for covering my favorite language ever

Lua is somewhere in my top 3 favorites, but I never get to use it much in day-to-day programming. I use it once in a while for trying to recreate stuff, though. (for example, a Tic-Tac-Toe app)

I'd love to see a video about fp-ts library for functional programming in typescript. It (un)suprisingly gains a lot of traction right now, at least in terms of npm downloads per week.

I use Awesome window manager as daily driver in my debian machine, which is fully written in Lua. So I had to learn a little bit of it in order to customize my desktop to my linking. I found it super easy to get my head around quickly and had a lot of fun configuring (after coming from Qtile which is written in Python).

@@ChristophBackhaus I think that functional programming goes well with object-oriented programmming. Scala is an example of that. Such style is possible even in Java with streams, records and some elements of pattern matching, but it's annoying there because streams are single-use and there needs to be a lot of boilerplate.

there's also this metatable feature of lua that gives special properties to tables, which allows users to simulate classes and perform operations on them

I love theese videos so much!

been waiting for this for a long time

It is also used in Adobe to create plugins for products like Lightroom and Photoshop.

@Fireship, do Django in 100 seconds! Lua is completely underrated. I played around with it to show my kids how to build their own Roblox games, and it was a joy to work with.

One of the distinctive features of Lua is its metatables and metamethods. Metatables allow customization of table behavior, enabling operators like addition and comparison to be defined for tables.

Eu programo em Lua já alguns anos e sempre enjeto código C no meio. Fica super legal para os propósitos que eu preciso, aínda mais para sistemas de embarcação!

what do you use lua for? embedded system?

Lua é a linguagem mais fácil de aprender :) Nunca pensei que ia ter um video sobre a linguagem lua aqui

This language looks cool actually. Lua can be found in most industrial embedded devices like sensors, PLC, and HMI development toolkit. I still don’t get why it is so underrated.

Its underrated because Google chose Python, and a lot of really important libraries followed suit. I believe in Lua supremacy.

​@@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.

this brings back memories, we used LUA to build homebrews for PSPs back in the days

I love the ability of Lua, to do quasi-oop with setmetatable, maybe you can do a piece on that!

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 😂

i love how im working on something that involves lua while also lua is also on other games such as garrys (for addon development, which is what i am doing currently, but i am also a 10 year vet and game dev on roblox so ya)

I was thinking during the video and lua was my first contact with lua progamming bots for Tibia, amazing and very easy language 🇧🇷

i love Lua so much

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.

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.

beautifully concise!

Still in school, and this 1:11 just made me understand functions

"A language that is known for being too underrated" - There isn't more exact than that, what do I say...

I will definitely be learning this.

This randomly popped up but now I can use this for rainmeter.

You can also create an index on a table just giving the key name and value: *local foo = { bar = 1 };* *print(foo.bar);* PS: *local* is practically mandatory in terms of best practices.
