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.

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.

[@SkyyySi]

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]

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 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.

[@cyberlawit8891]

Wow bro thanks for information

[@jameswashington4704]

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.

[@pixelstriko1642]

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

[@skaruts]

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'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.

Lua is a really cool programming language, some would even say that beginners should start with Lua and not Python for an introduction to programming.

[@seadrown6252]

I started with lua, making games on ROBLOX. I now do lua and python, (lua due to Roblox and python due to GCSE computer science), and I have to say I do enjoy lua more. It's syntax is very easy to pick up

[@ZephrymWOW]

Lua is a bad first language if you are not doing it for fun or planning on doing video game development. It teaches you bad habits and is very different from the majority of "real world" applications.

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

[@jxl721]

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

[@blanknaemguy]

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

[@ScipiPurr]

Back when I was still first learning programming I got super burnt out on C/C++ over the years. Lua was the language that reignited my love for programming and games development. It can be such a joy to use!

[@inserteunnombreapropiado9079]

Same history: I started to learn programming with C++ and it was hard. I mean, got many of the concepts of programming, but it wasn't funny. Then, I wanted to learn how to make games in Roblox and win money and I got to learn Lua. Now I don't make Roblox games, but I use Lua for pretty much any programming task I want.

[@savejeff15]

1:37 ... i'm head out.

[@mfaizsyahmi]

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.

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.

[@daiangan]

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

I know about Lua through Final Fantasy XI. I hear it forms the basis of how the endgame works there with enabling gear-swapping in mid-combat. Pretty cool where you can find Lua, honestly!

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.

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.

[@jesusmanuelmartinfernandez6947]

sounds great! why is not more popular nowdays?

[@futuza]

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.

[@RobertWildling]

Those fancy fluid logos - who makes them? And how? Any chance you could make a short tutorial about those? Really, really beautiful!

In Davinci Resolve (Or Fusion) you can just make a Fusion template with nodes and change the source image. Then you can reuse this template.
