Sales guy at the office: "So you see patterns in the code, you can read this cryptic mess?" — "Uh this is PHP, Its not the syntax that makes it hard to read, it's the dimwit who wrote it"

So, you start with a PHP website.
Nah, no hating on PHP here, this is not about language design or performance or strict type systems...
This is about architecture.
No backend web framework, just "plain PHP".
Well, I can deal with that. As long as there is some consistency, I wouldn't even mind maintaining a PHP4 site with Y2K-era HTML4 and zero Javascript.
That sounds like fucking paradise to me right now. 😍
But no, of course it was updated to PHP7, using Laravel, and a main.js file was created. GREAT.... right? Yes. Sure. Totally cool. Gotta stay with the times. But there's still remnants of that ancient framework-less website underneath. So we enter an era of Laravel + Blade templates, with a little sprinkle of raw imported PHP files here and there.
Fine. Ancient PHP + Laravel + Blade + main.js + bootstrap.css. Whatever. I can still handle this. 🤨
But then the Frontend hipsters swoosh back their shawls, sip from their caramel lattes, and start whining: "We want React! We want SPA! No more BootstrapCSS, we're going to launch our own suite of SASS styles! IT'S BETTER".
OK, so we create REST endpoints, and the little monkeys who spend their time animating spinners to cover up all the XHR fuckups are satisfied. But they only care about the top most visited pages, so we ALSO need to keep our Blade templated HTML. We now have about 200 SPA/REST routes, and about 350 classic PHP/Blade pages.
So we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + React + SPA 😑
Now the Backend grizzlies wake from their hibernation, growling: We have nearly 25 million lines of PHP! Monoliths are evil! Did you know Netflix uses microservices? If we break everything into tiny chunks of code, all our problems will be solved! Let's use DDD! Let's use messaging pipelines! Let's use caching! Let's use big data! Let's use search indexes!... Good right? Sure. Whatever.
OK, so we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + React + SPA + Redis + RabbitMQ + Cassandra + Elastic 😫
Our monolith starts pooping out little microservices. Some polished pieces turn into pretty little gems... but the obese monolith keeps swelling as well, while simultaneously pooping out more and more little ugly turds at an ever faster rate.
Management rushes in: "Forget about frontend and microservices! We need a desktop app! We need mobile apps! I read in a magazine that the era of the web is over!"
OK, so we enter the Era of Ancient PHP + Laravel + Blade + main.js + bootstrap.css + hipster.sass + REST + GraphQL + React + SPA + Redis + RabbitMQ + Google pub/sub + Neo4J + Cassandra + Elastic + UWP + Android + iOS 😠
"Do you have a monolith or microservices" -- "Yes"
"Which database do you use" -- "Yes"
"Which API standard do you follow" -- "Yes"
"Do you use a CI/building service?" -- "Yes, 3"
"Which Laravel version do you use?" -- "Nine" -- "What, Laravel 9, that isn't even out yet?" -- "No, nine different versions, depends on the services"
"Besides PHP, do you use any Python, Ruby, NodeJS, C#, Golang, or Java?" -- "Not OR, AND. So that's a yes. And bash. Oh and Perl. Oh... and a bit of LUA I think?"
2% of pages are still served by raw, framework-less PHP.32 -
My wife is a (semi-)pro gamer, so the only way it affects our dating is that I have to help her write LUA addons, performance analytics and Twitch bots.18

curl cheat.sh — get an instant answer to any question on (almost) any programming language from the command line
tldr
do curl cht.sh/go/execute+external+program to see how to execute external program in go
And this question: why I actually should I start the browser, and the browser has to downloads tons of JS, CSS and HTML, render them thereafter, only to show me some small output,
some small text, number or even some plot. Why can't I do a trivial query from the command line
and instantly get what I want?
I decided to create some service that will work as I think such a service should work.
And that is how wttr.in was created.
Nowadays you probably know, how to check the weather from the command line, but if not:
curl wttr.in
or
curl wttr.in/Paris
(curl wetter in Paris if you want to know the weather in Paris)
After that several other services were created (the point was to check how good the console
can solve the task, so I tried to create services providing information
of various nature: text, numbers, plots, pseudo graphic etc.):
curl rate.sx/btc # to check exchange rate of any (crypto)currency
curl qrenco.de/google.com # to QRenco.de any text
And now last but not least, the gem in this collection: cheat.sh.
The original idea behind the service was just to deliver a various UNIX/Linux command line cheat sheets via curl. There are several beautiful community driven cheat sheet repositories such as tldr, but the problem is that to use them you have to install them first, and it is quite often that you have no time for it, you just want to quickly check some cheat sheet.
With cheat.sh you don't need to install anything, just do:
curl cheat.sh/tar (or whatever)
you will get a cheat sheet for this command (if such cheat sheet exists inf one of the most popular community-driven cheat sheet repositories; but it surely does).
But then I thought: why actually show only existing cheat sheets? Why not generate cheat sheets or better to say on the fly? And that is how the next major update of cheat.sh was created.
Now you can simply do:
curl cht.sh/python/copy+files
curl cht.sh/go/execute+external+program
curl cht.sh/js/async+file+read
or even
curl cht.sh/python/копировать+файл
curl cht.sh/ruby/Datei+löschen
curl cht.sh/lua/复制文件
and get your question answered
(cht.sh is an alias for cheat.sh).
And it does not matter what language have you used to ask the question. To be short, all pairs (human language => programming language) are supported.
One very important major advantage of console oriented interfaces is that they are easily
programmable and can be easily integrated with various systems.
For example, Vim and Emacs plugins were created by means of that you can
query the service directly from the editor so that you can just write your
questions in the buffer and convert them in code with a keystroke.
The service is of course far from the perfection,
there are plenty of things to be fixed and to be implemented,
but now you can see its contours and see the contours of this approach,
console oriented services.
The service (as well as the other mentioned above services) is opensource, its code is available here:
https://github.com/chubin/cheat.sh
What do you think about this service?
What do you think about this approach?
Have you already heard about these services before?
Have you used them?
If yes, what do you like about them and what are you missing?26 -
"Running the sample code is easy! Just git clone, make sure python, lua, gcc, docker and cuda are installed, and run ./install.sh. Easy!"

PineScript is absolute garbage.
It's TradingView's scripting language. It works, but it's worse than any language I have ever seen for shoddy parsing. Its naming conventions are pretty terrible, too:
transparency? no, "transp"
sum? no, cum. seriously. cum(array) is its "cumulative sum."
There are other terrible names, but the parser is what really pisses me off.
1) If you break up a long line for readability (e.g. a chained ternary), each fragment needs to be indented by more than its parent... but never by a multiple of 4 spaces because then it isn't a fragment anymore, but its own statement.
2) line fragments also cannot end in comments because comments are considered to be separate lines.
3) Lambdas can only be global. They're just fancy function declarations. Someone really liked the "blah(x,y,z) =>" syntax
4) blocks to `if`s must be on separate lines, meaning `if (x) y:=z` is illegal. And no, there are no curly braces, only whitespace.
There are plenty more, but the one that really got me furious is:
98) You cannot call `plot()`, `plotshape()`, etc. if they're indented! So if you're using non-trivial logic to optionally plot things like indicators, fuck you.
Whoever wrote this language and/or parser needs to commit seppuku.rant or python? pinescript or fucking euphoria? or ruby? why can't they just use lua? or javascript? tradingview17 -
I had to open the desktop app to write this because I could never write a rant this long on the app.
This will be a well-informed rebuttal to the "arrays start at 1 in Lua" complaint. If you have ever said or thought that, I guarantee you will learn a lot from this rant and probably enjoy it quite a bit as well.
Just a tiny bit of background information on me: I have a very intimate understanding of Lua and its c API. I have used this language for years and love it dearly.
[START RANT]
"arrays start at 1 in Lua" is factually incorrect because Lua does not have arrays. From their documentation, section 11.1 ("Arrays"), "We implement arrays in Lua simply by indexing tables with integers."
From chapter 2 of the Lua docs, we know there are only 8 types of data in Lua: nil, boolean, number, string, userdata, function, thread, and table
The only unfamiliar thing here might be userdata. "A userdatum offers a raw memory area with no predefined operations in Lua" (section 26.1). Essentially, it's for the API to interact with Lua scripts. The point is, this isn't a fancy term for array.
The misinformation comes from the table type. Let's first explore, at a low level, what an array is. An array, in programming, is a collection of data items all in a line in memory (The OS may not actually put them in a line, but they act as if they are). In most syntaxes, you access an array element similar to:
array[index]
Let's look at c, so we have some solid reference. "array" would be the name of the array, but what it really does is keep track of the starting location in memory of the array. Memory in computers acts like a number. In a very basic sense, the first sector of your RAM is memory location (referred to as an address) 0. "array" would be, for example, address 543745. This is where your data starts. Arrays can only be made up of one type, this is so that each element in that array is EXACTLY the same size. So, this is how indexing an array works. If you know where your array starts, and you know how large each element is, you can find the 6th element by starting at the start of they array and adding 6 times the size of the data in that array.
Tables are incredibly different. The elements of a table are NOT in a line in memory; they're all over the place depending on when you created them (and a lot of other things). Therefore, an array-style index is useless, because you cannot apply the above formula. In the case of a table, you need to perform a lookup: search through all of the elements in the table to find the right one. In Lua, you can do:
a = {1, 5, 9};
a["hello_world"] = "whatever";
a is a table with the length of 4 (the 4th element is "hello_world" with value "whatever"), but a[4] is nil because even though there are 4 items in the table, it looks for something "named" 4, not the 4th element of the table.
This is the difference between indexing and lookups. But you may say,
"Algo! If I do this:
a = {"first", "second", "third"};
print(a[1]);
...then "first" appears in my console!"
Yes, that's correct, in terms of computer science. Lua, because it is a nice language, makes keys in tables optional by automatically giving them an integer value key. This starts at 1. Why? Lets look at that formula for arrays again:
Given array "arr", size of data type "sz", and index "i", find the desired element ("el"):
el = arr + (sz * i)
This NEEDS to start at 0 and not 1 because otherwise, "sz" would always be added to the start address of the array and the first element would ALWAYS be skipped. But in tables, this is not the case, because tables do not have a defined data type size, and this formula is never used. This is why actual arrays are incredibly performant no matter the size, and the larger a table gets, the slower it is.
That felt good to get off my chest. Yes, Lua could start the auto-key at 0, but that might confuse people into thinking tables are arrays... well, I guess there's no avoiding that either way.13 -
A Fellow Ranter said I should introduce myself, so here I go.
Me = {
Gender = "Male",
CodeOfChoise = {"lua", "PHP"},
Age = "28"
Location = "404"
}
No really here we go, I am Rex, I am dyslexic and forget code really badly but it does not stop me from trying to have fun with some ideas, I use mostly PHP these days but when I want to make a quick windows tool I use a app called AMS or AutoPlayMedia Studios what as a nice lua scripting language back end.
I been coding on and off for many years since I was about 15 and I been in love with computers since I was about 6 (don't tell my wife).
So far I like the site, its better then Twitter and Facebook as it's code related and fun to read and some stuff gets the cogs a turning.
I don't have any real foot print in the dev world, I get by but I not here to be loved, or to be big in any field, I am here because I enjoy my tech.
I leave this little introduce me with a question, what was your first or first memorial computer.
Mine was the Acorn A4000 Mixed with parts from the A3000 and A5000's :) she was a little bit of a mix match.18 -
I'M SO PROUD, I WROTE A FULLY-FUNCTIONAL JSON PARSER!
I used some data from the devRant API to test it :D
(There's a lot of useful tests in the devRant API like empty arrays, mixed arrays and objects, and nested objects)
Here's the devRant feed with one rant, parsed by Lua!
You can see the type of data (automatically parsed) before the name of the data, and you can see nested data represented by indentation.
The whole thing is about 200 lines of code, and as far as I can tell, is fully-featured.24 -
who ever has this as their skill set are legends!!
made me laugh going through thousands of lines of skills :D

I know it's not done yet but OOOOOH boy I'm proud already.
Writing a JSON parser in Lua and MMMM it can parse arrays! It converts to valid Lua types, respects the different quotation marks, works with nested objects, and even is fault-tolerant to a degree (ignoring most invalid syntax)
Here's the JSON array I wrote to test, the call to my function, and another call to another function I wrote to pretty print the result. You can see the types are correctly parsed, and the indentation shows the nested structure! (You can see the auto-key re-start at 1)
Very proud. Just gotta make it work for key/value objects (curly bracket bois) and I'm golden! (Easier said than done. Also it's 3am so fuck, dude)15 -
This is going to be a rant, but personally, I'm pleased with the outcome of my life now.
I was part of a community for a few years and decided to help them out with my knowledge of programming Lua nearly 2 years ago since they lacked developers for the project itself.
Since it was sort of a custom language that they modified how Lua worked on it, it took me a bit to adapt, but within a few weeks, I was pretty fluent in this so-called custom language they had. Began working on some major updates, additions, removals, and just optimizing this code base. It was a pretty old code base and needed a good chunk of love.
A few months later, I've implemented loads of features, optimized the base whenever I could, and then things start taking a turn for the worse. We get new 'developers' who haven't ever coded the language, and worse they couldn't afford to provide them development servers thus they ended up breaking my servers. I helped them and they learned, they were decent, but now the Seniors and CEO's of the project began to take a toll on me.
I was told that this community had a reputation of driving out developers, ruining their reputations, and that is what started happening. I started getting questioned if I was loyal to helping them, that I've become lazy, even though they were explained I've had mental health issues for a few years and have been hospitalized multiple times.
These sort of attacks kept happening for months, and then they finally pushed my buttons, where I was talking to another Senior of how we should redo the base since it's just so massive and a few tiny updates to the base take a few days to implement across the entire code. What instead happened was that I went to sleep, and this Senior told the CEO I was going to steal the code base and go sell it...
I woke up to messages of how the CEO is all pissed off, and that this what the Senior said. At this point, I started responding with, fuck it. I was so sick and fucking tired of their bullshit. I was the only fucking competent developer, and I did more work in the few months I was there then some people did in 2 or 3 years.
A few hours later I decided to go chat with the CEO and explained what was truly brought up, and he just brushed it off like I was lying. At that point, I lost it. I told him why the code base was horrible since he hired stupid ass developers. He didn't know how to code. People wanted certain items, and he wouldn't be able to add them for fucking months and players sit there making fun of it. Some people state the only differences they see within the code is the code I've done. Basically, he was an incompetent fuck that said he knew what he was doing, and had all these big plans for the future yet couldn't listen to the only competent developer and fucking claimed bullshit.
Now a few months have gone by, I'm looking at their community and it's basically dead with no proper updates except for copy and paste updates claiming to be custom coded. While I'm working on my real life businesses (Which are currently being a headache, but within the year should resolve its issues), starting University for my Computer Science degree here soon, and even considering building my own game here.
Basically, karma is a bitch and that's why when you get loyal people in your life, keep them. (Writing this at 3 am after a few drinks, hopefully, it made sense, I think it does.)
Anyways, goodnight everyone.5 -
EEEEEEEEEEEE Some fAcking languages!! Actually barfs while using this trashdump!
The gist: new job, position required adv C# knowledge (like f yea, one of my fav languages), we are working with RPA (using software robots to automate stuff), and we are using some new robot still in beta phase, but robot has its own prog lang.
The problem:
- this language is kind of like ASM (i think so, I'm venting here, it's ASM OK), with syntax that burns your eyes
- no function return values, but I can live with that, at least they have some sort of functions
- emojies for identifiers (like php's $var, but they only aim for shitty features so you use a heart.. ♥var)
- only jump and jumpif for control flow
- no foopin variable scopes at all (if you run multiple scripts at the same time they even share variables *pukes*)
- weird alt characters everywhere. define strings with regular quotes? nah let's be [some mental illness] and use prime quotes (‴ U+2034), and like ⟦ ⟧ for array indexing, but only sometimes!
- super slow interpreter, ex a regular loop to count to 10 (using jumps because yea no actual loops) takes more than 20 seconds to execute, approx 700ms to run 1 code row.
- it supports c# snippets (defined with these stupid characters: ⊂ ⊃) and I guess that's the only c# I get to write with this job :^}
- on top of that, outdated documentation, because yea it's beta, but so crappin tedious with this trail n error to check how every feature works
The question: why in the living fartfaces yolk would you even make a new language when it's so easy nowadays to embed compilers!?! the robot is apparently made in c#, so it should be no funcking problem at all to add a damn lua compiler or something. having a tcp api would even be easier got dammit!!! And what in the world made our company think this robot was a plausible choice?! Did they do a full fubbing analysis of the different software robots out there and accidentally sorted by ease of use in reverse order?? 'cause that's the only explanation i can imagine
Frillin stupid shitpile of a language!!! AAAAAHHH
see the attached screenshot of production code we've developed at the company for reference.
Disclaimer: I do not stand responsible for any eventual headaches or gauged eyes caused by the named image.
(for those interested, the robot is G1ANT.Robot, https://beta.g1ant.com/)4 -
And already, I have completed my New Year's resolution! (SPEED RUN!)
I've just published my first completed project!
https://algorythm-dylan.github.io/t...
It allows you to make advanced cross-platform console applications. It's cross-platform curses, basically.
I spent quite a lot of time on the docs, so you can read all about it there. There's still a lot of stuff to do, but the very foundation is there, and it's everything you need(ish). It can just be a little inconvenient at times without helper functions for drawing, or adding strings, and such.
I'm currently binding it to Lua, which is going to be super fun to use!
Happy with this first version5 -

Chrome, Firefox, and yes even you Opera, Falkon, Midori and Luakit. We need to talk, and all readers should grab a seat and prepare for some reality checks when their favorite web browsers are in this list.
I've tried literally all of them, in search for a lightweight (read: not ridiculously bloated) web browser. None of them fit the bill.
Yes Midori, you get a couple of bonus points for being the most lightweight. Luakit however.. as much as I like vim in my terminal, I do not want it in a graphical application. Not to mention that just like all the others you just use webkit2gtk, and therefore are just as bloated as all the others. Lightweight my ass! But programmable with Lua, woo! Not like Selenium, Chrome headless, ... does that for any browser. And that's it for the unique features as far as I'm concerned. One is slow, single-threaded and lightweight-ish (Midori) and another has vim keybindings in an application that shouldn't (Luakit).
Pretty much all of them use webkit2gtk as their engine, and pretty much all of them launch a separate process for each tab. People say this is more secure, but I have serious doubts about that. You're still running all these processes as the same user, and they all have full access to the X server they run under (this is also a criticism against user separation on a single X session in general). The only thing it protects against is a website crashing the browser, where only that tab and its process would go down. Which.. you know.. should a webpage even be able to do that?
But what annoys me the most is the sheer amount of memory that all of these take. With all due respect all of you browsers, I am not quite prepared to give 8 fucking gigabytes - half the memory in this whole box! - just for a dozen or so tabs. I shouldn't have to move my web browser to another lesser used 16GB box, just to prevent this one from going into fucking swap from a dozen tabs. And before someone has a go at the add-ons, there's 4 installed and that's it. None of them are even close to this complete and utter memory clusterfuck. It's the process separation. Each process consumes half a GB of memory, and there's around a dozen of them in a usual browsing session. THAT is the real problem. And I want to get rid of it.
Browsers are at their pinnacle of fucked up in my opinion, literally to the point where I'm seriously considering elinks. Being a sysadmin, I already live my daily life in terminals anyway. As such I also do have resources. But because of that I also associate every process with its cost to run it, in terms of resources required. Web browsers are easily at the top of the list.
I want to put 8GB into perspective. You can store nearly 2 entire DVD movies in that memory. However media players used to play them (such as SMPlayer) obviously don't do that. They use 60-80MB on average to play the whole movie. They also require far less processing power than YouTube in a web browser does, even when you download that exact same video with youtube-dl (either streamed within the media player or externally). That is what an application should be.
Let's talk a bit about these "complicated" websites as well. I hate to break it to you framework web devs, but you're a dime a dozen. The competition is high between web devs for that exact reason. And websites are not complicated. The document itself is plain old HTML, yes even if your framework converts to it in the background. That's the skeleton of your document, where I would draw a parallel with documents in office suites that are more or less written in XML. CSS.. oh yes, markup. Embolden that shit, yes please! And JavaScript.. oh yes, that pile of shit that's been designed in half a day, and has a framework called fucking isEven (which does exactly what it says on the tin, modulo 2 be damned). Fancy some macros in your text editor? Yes, same shit, different pile.
Imagine your text editor being as bloated as a web browser. Imagine it being prone to crashing tabs like a web browser. Imagine it being so ridiculously slow to get anything done in your productivity suite. But it's just the usual with web browsers, isn't it? Maybe Gopher wasn't such a bad idea after all... Oh and give me another update where I have to restart the browser when I commit the heinous act of opening another tab, just because you had to update your fucking CA certs again. Yes please!23 -
Hello devRant, this is going to be my first time posting on the site.
I work for a gaming community on the side, and today one of the managers asked me to implement a blacklist system into the chat and reactivate the previously existing one temporarily. This shouldn't have had any issues and should've been implemented within minutes. Once it was done and tested, I pushed it to the main server. This is the moment I found out the previous developer apparently decided it would be the best idea to use the internal function that verifies that the sender isn't blacklisted or using any blacklisted words as a logger for the server/panel, even though there is another internal function that does all the logging plus it's more detailed than the verification one he used. But the panel he designed to access and log all of this, always expects the response to be true, so if it returns false it would break the addon used to send details to the panel which would break the server. The only way to get around it is by removing the entire panel, but then they lose access to the details not logged to the server.
May not have explained this the best, but the way it is designed is just completely screwed up and just really needs a full redo, but the managers don't want to redo do it since apparently, this is the best way it can be done.7 -

Here's one that involves Windows, Linux (at the same time!), WInZip, Python, Lua and Minecraft, sort of.
So, when I get depressed I often find that old 2011 Minecraft videos help a lot from the nostalgia boost. If its stupid, but it works, it isn't stupid. Anyways, I was thinking about how much fun it must have been to just fuck around with code and make something like Minecraft. Naturally, I got a huge code boner and really wanted to do something I hadn't in a while: binding c to a higher level language.
This time around, I wanted to try Python. C + Python seems like a good pair. I watched a tutorial and it seemed pretty interesting and simple enough but I remembered that I actually like Lua a lot better than Python, so I went to the download page of Lua.
The download is a tar.gz so I let out a sigh and start typing "WinZip" into google. But no, fuck that, I hate 3rd party decompression programs on Windows. They all just give me this eerie feeling.
"This would be so much fucking easier on Linux"...
I remember that I haven't tried the Windows Subsystem for Linux. I guess it's time, isn't it?
I read the docs of how to do it. Nice little touch, they tell you how to enable WSL from PowerShell but don't mention the GUI way to do it. It's genuinely a nice touch.
So I get everything installed and go to the app store to choose a distro. I want Ubuntu. I click the Install button...
...
... "Something unexpected happened"
Windows and their fucking useless error messages. Jesus, okay. I restart computer. Same issue. I update Windows. Same thing. Uninstall WSL. Reboot. Install WSL. Reboot. Same thing. HOLY SHIT.
Went to bed. Woke up. Tried to install Ubuntu.
"Yea ok lul i'll work this time for no reason"
Finally unzipped Lua.4 -
I think I'm not as socially awkward as I once believed. I realize I just have nothing in common with the majority of people.
I don't watch sports, I don't care about cars, or fantasy football, or have any hobbies non-developers would find interesting.
If you want to talk about software patterns, finite automaton, Lua/C APIs, etc, then fuck yeah I'll talk to you all day long.5 -
Just found out about Yue, a GUI library for Node.js, Lua and C++ (and owners of the "gui" package on npm).
It is so awesome! The RAM usage is so low compared to Electron! Of course it has its limitations and doesn't use HTML + CSS + JavaScript, but you can still build really good applications with it!
I'll show you what I'm making at the moment soon, so stay tuned!
Anyways I've built the same application in Electron and Yue, here's the comparison of the RAM usage:16 -
Hey guys I'd like to share a Lua-based shell I've been working on the past few years. It's entirely complete, allows for all windows and Linux commands. I've been working very hard on it so I'm super excited to share it with you all. Here's the source.

Wow, I think I might be closer to done than I thought I would be!
Double buffered console library, works cross-platform with support for color! Color was a challenge because of the differences between Linux and Windows but I think my solution was okay!
The only thing I have left is reading input and I don't think that's going to be terribly hard! Then, I'm gonna bind it to Lua and make really cool console applications like a portable console notepad lol.

So I bought a smart watch to go with my Samsung Galaxy back when I was 12, and upon inspecting the watchface maker app I came across lua scripting files. This amazed me. Animations, complex math, hexadecimal color system, variables, sensors...
I spent about four months
learning/experimenting with lua until I discovered arduino and C++.
I am now 14 and have been fascinated with robotics and learned java and dos since.2 -
Progress: I have Lua code running, however it returns an error every time.
An error containing the result I wanted.3 -
Learned Lua for an hour, I think its a fun language to mess around, but i’m still figuring out what i’m going to use it for...10

Dev of 15 years here. All my career historically started and evolved/revolved around Microsoft in one way or the other, so was my exposure to only DOS and the Windows as a child and growing up.
Like already discussed in multiple rants here, I was one of those naturally Windows -favoring ppl through all my life. That is not to say I didn't try Linux here and there, for hosting of personal projects, as one usually does. But it never quite stuck with me as a personal daily driver, mainly because all I ever needed for personal use was a browser, discord, and Steam/GOG/Epic Games store for gaming (work-wise I always had and still have company provided laptops which are OF COURSE Windows powered)
Anyway, maybe you can see where I'm going with this... I recently gave Nobara Linux a go (Glorious Eggroll's Fedora flavor, with some custom kernel patches) and I have to say, not thinking of going back to Windows at all.
Just a few thoughts on comparing two sets of experiences with Win vs Nobara
- Win definitely feels more sluggish
- Nobara's default desktop env was Gnome 42 with some extensions pre-enabled. I dove right into hacking/customizing it to my tastes and it looked glorious. Never would have achieved this customization with Win
- I was using RDP to remote into my work laptop from my personal desktop setup with Windows and I still successfully do so with Remmina now in Linux
- A week ago I dove deeper and installed Awesome window manager as a UI and mh boy does this feel intimidating at first. But then the allure of having nice window managing experience was too strong, and 15 years of coding do help with just seeing a new language and kinda feeling at home instantly (Lua language for AwesomeWM customization/themes). Fast forward a week and now I'm sitting happily with 3 monitor setup, one of them vertical, all properly auto aligned with arandr on startup, variety+wal for wallpaper auto circling and applying a theme out of main wallpaper colors every so often (+wrote a script to put those main colors into my RGB peripherals via OpenRGB)
- Gaming. I still game, Steam Deck from steam gave me all the confidence to set up Linux gaming that I needed. I think I am now properly versed in all things Wine/Proton/Lutris/Bottles/Heroic Games Launcher, you name it. Recently finished Cyberpunk 2077.
ANYWAY, thank you for coming to my Linux appreciation TED talk. It's amazing. -
That specific moment a C# Developer (me) makes an API for Modding his own game but the mod language is Lua.
(And it works)6 -
Customer: I want to be included in any and all design and development meeting in the future.
Me: OK, I mean, I'm just one person so there's not formal meetings as such...
Customer: Nevertheless, I wish to be included and ensure my needs are met.
Some time passes.
Me: So, I'm thinking of swapping out the old Beanshell interface, cos, really... Interpreted, scriptable Java isn't great and most users don't want to write Java just to run some jobs. Could you help me with creating an API that fits you and your departments needs?
Customer: No, I'm way to busy to deal with this right now!
Me: And when would be convenient for you?
Customer: I don't know, just not now.
To this day, despite successfully integrating the rhino js engine into the app, part of the software I develop has a bean shell interface rather than js, Python or lua.
-_- I hate bean shell... -
Reading about Lua, see this:
"Lua arrays are 1-based: the first index is 1 rather than 0 as it is for many other programming languages (though an explicit index of 0 is allowed)."
*close tab*2 -
The English language.
Maybe my fascination with code that reads like a book comes from a desire for my code to be understood. Maybe it comes from novelty. But it really does send tingles down my spine when it reads like literature.
That's one of the largest reasons Lua is my favorite language and Java is one of my least favorite (sounds like a guy with a bad stutter, always repeating himself)2 -
What is your opinion on hopping from one language to another?
So far I have been programming for a little over a year and have used Python, Lua, Javascript amd C++, planning on trying Java in the very near future.
I've had quite a positive experience with switching languages so far, especially when starting out. Some concepts I wouldn't understand, but after seeing them from a perspective of a different language I finally got it. Do you think it's good to know a lot of languages, or in the long run is it better to master one?8 -
what kind of dumb fuck you have to be to get the react js dev job in company that has agile processes if you hate the JS all the way along with refusing to invest your time to learn about shit you are supposed to do and let's add total lack of understanding how things work, specifically giving zero fucks about agile and mocking it on every occasion and asking stupid questions that are answered in first 5 minutes of reading any blog post about intro to agile processes? Is it to annoy the shit out of others?
On top of that trying to reinvent the wheels for every friggin task with some totally unrelated tech or stack that is not used in the company you work for?
and solution is always half-assed and I always find flaw in it by just looking at it as there are tons of battle-tested solutions or patterns that are better by 100 miles regarding ease of use, security and optimization.
classic php/mysql backend issues - "ooh, the java has garbage collector" - i don't give a fuck about java at this company, give me friggin php solution - 'ooh, that issue in python/haskel/C#/LUA/basically any other prog language is resolved totally different and it looks better!' - well it seems that he knows everything besides php!
Yeah we will change all the fucking tech we use in this huge ass app because your inability to learn to focus on the friggin problem in the friggin language you got the job for.
Guy works with react, asked about thoughts on react - 'i hope it cease to exists along with whole JS ecosystem as soon as possible, because JS is weird'. Great, why did you fucking applied for the job in the first place if it pushes all of your wrong buttons!
Fucking rockstar/ninja developers! (and I don't mean on actual 'rockstar' language devs).
Also constantly talks about game development and we are developing web-related suite of apps, so why the fuck did you even applied? why?
I just hate that attitude of mocking everything and everyone along with the 'god complex' without really contributing with any constructive feedback combined with half-assed doing something that someone before him already mastered and on top of that pretending that is on the same level, but mainly acting as at least 2 levels above, alas in reality just produces bolognese that everybody has to clean up later.
When someone gives constructive feedback with lenghty argument why and how that solution is wrong on so many levels, pulls the 'well, i'm still learning that' card.
If I as code monkey can learn something in 2 friggin days including good practices and most of crazy intricacies about that new thing, you as a programmer god should be able to learn it in 2 fucking hours!
Fucking arrogant pricks!8 -
Another update on my 3D Software Engine:
Big progress since my last rant.
I now have a simple lightning with the Gouraud Shading Algorithm!
Looks really cool now!
Btw for those who are interested, I am following a tutorial but I'm translating everything to Lua/LÖVE2D. Here's the link to the tutorial:
https://davrous.com/2013/06/...8 -
I started with C#at the age of 12, it was way too complicated and I learned Lua for Computer craft instead. Next I learned Ruby for RPG Maker and finally Javascript for web Dev stuff.
Now comfortable enought with Javascript but put off by its quirks I learned Java for compiling faulty minecraft mods, but I only fully learned it in school.
At the same time I learned python and quite liked it for scripting, but ultimately it was not a good match for my projects.
Disapointed with Java I returned to C# and liked it quite a lot, but started learning C++. After touching my first Microcontroller I learned C and I've stuck with it as my favorite language.
Along the way I picked up Kotlin, in case I need to do some Java shit. Much better.
But how did I come to an understanding of programming. Well I got better after each time I got a layer deeper until I hit silicon.
I had tinkered with electronics since I was 15 so I just had to study some boolean mathematics in school and some vintage computers architecture and instruction sets and...
Then I finally understood how that shit I wrote in Lua way back when was actually executed by my hardware.
Allways dig deeper and you'll find enlightenment eventually. -
I don't get it.
I tried Kotlin on Android just for fun, and it doesn't support binary data handling, not even unsigned types until the newest version. Java suffers from the same disease.
How does one parse and process binary data streams on such a high end system? Not everything is highlevel XML or JSON today.
And it's not only an Android issue.
Python has some support for binary data, and it's powerful, but not comfortable.
I tried Ruby, Groovy, TCL, Perl and Lua, and only Lua let's you access data directly without unnecessary overhead.
C# is also akward when it comes to data types less than the processer register width.
How hard can it be to access and manipulate data in its natural and purest form?
Why do the so called modern programming language ignore this simple aspect that is needed on an everyday basis?11 -
Making games for my TI-Nspire CX CAS is so much fun!
It's so simple but you can do a lot with it. It's also a bit of a challenge because you don't have a huge API with lots of methods and events. You have to use what you have.
Oh btw you can program it with Lua!15 -
Lua is one of the stupidest languages to ever exist.
Oh, the language is easy to learn? The syntax is friendly? There's only like negative 10 functions you ever need to know? Everything is a table?
EVERYTHING IS A TABLE?! WTF CARES? WHAT ABOUT NIL?!
The arrogance this language has is extraordinary, literally. No lang, except Lua, imposes such an opinionated dichotomy. Everything is a fucking table, or, it's nil. -- That's so fucking stupid.
And look, I get it, this lang (oh sorry, scripting language (?)) CAN be good and fun and whatever... the moment you start to do IO is the literal end of days.
Everything is nil. Except, if it's defined... then it's not nil. -- OK. That sounds sensible/reasonable enough. -- What if it's not defined? You get nil. What if it's not the right data? You get nil. Do I get errors/exceptions or whatever? No, absolutely not, you get nil... unless the application you're using with Lua with has a lib that handles that.
There are so many more issues I have with this lang, but honestly... Am I fucking missing something? Is this lang like actually super dooper awesome and I'm missing something? -- I can't not look at this language as just dumb and arrogant. -- It's literally a language where you have to manage and remember ALL conceivable state at ALL times.11 -
Who thought Lua was a good idea for extending gameplay functionality??
It's weakly typed, has no OOP functionality and no namespace rules. It has no interesting data structures and tables are a goddamn mystery. Somebody made the simplest language they could and now everybody who touches it is given the broadest possible tools to shoot themselves in the foot.
Lua's ease of embedding into C++ code is a fool's paradise. Warcraft 3's JASS scripting language had way more structure and produced much better games, whilst being much simpler to work with than Lua.
All the academics describing metatables as 'powerful extensionality' and a fill-in for OOP are digging the hole deeper. Using tables to implement classes doesn't work easily outside school. Hiding a self:reference to a function inside of syntactic sugar is just insanity.
Nobody expects to write a triple-A game in lua, but they are happy to fob it off to kids learning to program. WoW made the right choice limiting it to UI extensions.
Fighting the language so you can try and understand a poorly documented game engine and implement gameplay features as the dev's intend for 'modders', is just beyond the pale. It's very difficult to figure out what the standard for extending functionality is, when everybody is making it up as they go along and you don't have a strongly-typed and structured language to make it obvious what the devs intended.
If you want to give your players a coding sandbox, make the scripting language yourself like JASS. It will be way better fit for purpose, way easier to limit for security and to guarantee reasonable performance. Your players get a sane environment to work in and you just might get the next DOTA.
Repeatedly shooting yourself in the foot on invisible syntax errors and an incredibly broad language is wasted suffering for kids that could be learning the programming concepts that cross all languages way quicker and with way more satisfying results.
Lua is hot garbage for it's most popular application, I really don't get it. Just stop!24 -
Hey everyone!
I'm on the hunt for new and exciting languages!
I'll state the ones I already know:
Python, Haskell, C(++), C#, Java, JavaScript, Ruby, Rust, Lua, about every kind of Basic, some branches of Lisp, BrainF**k, assembly, Octo (Chip-8) and GML(basically JavaScript).
I've also learnt some styling languages:
Html, CSS, Markup and Markdown.
Some misc languages too: Regex and a runny bit of the Wolfram Language.
Also I'm kind of limited to Windows, Linux and Android, as I do not own any Apple hardware except I have access to an old iPad, so are languages like Swift still good?
Thanks!28 -
Not quite a rant, but looking for opinion/advice.
I have been programming for a little over a year now, excluding those cringy Lua scripting days with if statement hell. I'm pretty far ahead most of the people in my course (1st year Software Engineering), but I'm at this awkward point where I know quite a bit but not enough. All of my projects so far have been small 1-2 source file programs, mostly in javascript although Python is my main hoe. At the moment I'm reading a book on machine learning and I feel like I'm doing fine, not struggling too much with it, but I don't feel confident at all in my abilities. I had two programming internship interviews half a year ago, both of which I wasn't accepted in. I've been thinking of contributing to an open source project lately to get some "real world" experience but I can't find a good project to start with and just don't feel like I'm good enough. There are also a lot of small things I come across such as async and coroutines in Python which I'm not familiar with yet and they make my confidence drop even lower. I'm guessing most of you have been in a similar position. Would you have any advice for me? Should I search for a project or should I keep on studying with books?2 -
To everyone who wants a terminal editor but hates how overly complicated vim/emacs is:

YouTube is so fuckin weird. A year ago I made some Lua tutorials and got no new subscribers. When I started, I had 8.
I have not posted any since.
But since then, I get a steady few per month.
I have over a hundred now?7 -
Holy fuck... Ruby has the best fucking syntax ever!
Ruby is so awesome!!!! (But Lua is a bit better)9 -
Lua, tables ("arrays") start at 1.
It also has no sleep function and its defacto package manager (luarocks) has almost never worked for me without some serious fuckery7 -
If you've ever tried using Go plugins raise your hand.
If you've ever tried doing plugins in Go, raise your hand.
If you think that the following rant will be interesting, raise your hand.
If you raised your hand, press [Read More]:
This is a tale of pain and sorrow, the sorrow of discovering that what could be a wonderful feature is woefully incomplete, and won't be for a very long time...
Go plugins are a cool feature: dynamically load pre-compiled code, and interact with it in a useful and relatively performant way (e.g. for dynamically extending the capabilities of your program). So far it sounds great, I know right?
Now let me list off some issues (in order of me remembering them):
1. You can't unload them (due to some bs about dlopen), so you need to restart the application...
2. They bundle the stdlib like a regular Go binary, despite the fact that they're meant to be dynamic!
3. #2 wouldn't be so bad if they didn't also require identical versions of all dependencies in both binaries (meaning you'd need to vendor the dependencies, and also hope you are using the right Go version).
4. You need to use -trimpath or everything dies...
All in all, they are broken and no one is rushing to fix it (literally, the Go team said they aren't really supporting it currently...).
So what other options are there for making plugins in Go?
There's the Hashicorp method of using RPC, where you have two separate applications one the plugin, one the plugin server, and they communicate over RPC. I don't like it. Why? Because it feels like a hack, it's not really efficient and it carries a fear of a limitation that I don't like...
Then we come to a somewhat more clever approach: using Lua (or any other scripting language), it's well known, it's what everyone uses (at least in games...). But, it simply is too hard to use, all the Go Lua VMs I could find were simply too hard to set up...
Now we come to the most creative option I've seen yet: WASM. Now you ask "WASM!? But that's a web thing, how are you gonna make that work?" Indeed, my son, it is a web thing, but that doesn't mean I can't use it! Someone made a WASM VM for Go, and the pros are that you can use any WASM supporting language (i.e. any/all of them). Problem inefficient, PITA to use, and also suffers from the same issues that were preventing me from using Lua.
Enter Yaegi, a Go interpreter created by the same guys who made (and named) Traefik. Yes, you heard me right, an INTERPRETER (i.e. like python) so while it's not super performant (and possibly suffering from large inefficiency issues), it's very easy to set up, and it means that my plugins can still be written in Go (yay)! However, don't think this method doesn't have its own issues, there's still the problem of effectively abstracting different types of plugins without requiring too much boilerplate (a hard problem that I'm actively working on, commits coming soon). However, this still feels to be the best option.
As you can see, doing plugins in Go is a very hard problem. In the coming weeks (hopefully), I'm going to (attempt to at least) benchmark all the different options, as well as publish a library that should help make using Yaegi based plugins easier. All of this stuff will go (see what I did there 😉) in a nice blog post that better explains the issues and solutions. But until then I have some coding to do...
Have a good night(/day)!14 -
Chased a bug for nearly a week. Huge code base, over 2mn lines consisting of a mess of C++, Python and Lua glued together.. Wrote a very complex distributed computational framework. End up with a elusive compiler bug in GCC.. FML

Good evening programmers, IT's, devranters and memeians.
I would like to use a little bit of your collective conciousness - the hive mind if you will.
I've been working on my automation system for quite a while and I've received some exposure from non-programmers - which resulted in more questions than suggestions.
I would like to ask you guys to give me some suggestions as to what I could add to my system.. that is, if you have time..
The program in short (if you don't want to read the readme file) is an automation system scriptable in pure Lua.
It utilizes Selenium for web automations, NAudio for audio operations and Moonsharp as an interpreter.
While my tester friends say that they use it for the actual testing, I myself found it very useful in writting bots (for browser games for example).
Here's the github link: https://bit.ly/2GDu92g
Thanks a ton!

Why isn't the Lua scripting language widely used in the industry? It's flexible, modular and it's packages aren't bad; seems like a great fit.8

Does LUA have anything similar to the GIL in Python? Because my code seemed to be updating the same piece of memory at once

Last rant was about games and graphics cards (admittedly not received too well), time for a rant about game development houses.. especially you EA.
So yesterday a friend of mine showed me in one of our Telegram chats that he'd modified some cheats in an old FPS game by editing these scripts (not Lua for some reason) that the game used as a.. configuration language I guess? He called the result a tank cemetery 🙃
Honestly the game looked a lot like Medal of Honor to stoned me at the time, so I figured, well why not fire up that old nx7010 I had laying around for so long, get a new Debian installation on that and rip the Medal of Honor: Allied Assault war chest that I still had, and play it on one of my more modern laptops? Those CD's are now very old anyway, maybe time to archive those before they rot away.
So I installed Debian on it again, looked up how to rip CD's from the command line, and it seemed that dd could do it - just give /dev/cdrom as the input file, and wherever you want to store your copy as the output file. Brilliant! Except.. uh, yeah. It wasn't that easy. So after checking the CD and finding that it was still pristine, and seeing another CD in that war chest fail just the same, I tried burning and then ripping a copy of Debian onto another CD.. checksummed them and yes, it ripped just fine, bit for bit equal. So what the fuck EA, why is your game such a special snowflake that it's apparently too difficult to even spin up the drive to be copied?
So I looked around on plebbit and found this: https://reddit.com/r/DataHoarder/... - the top comment of that post shattered all my hopes for this disc to be possible to rip. Turns out that DRM schemes intentionally screw up the protocols that make up a functioning disc, and detecting those fuck-ups is part of the actual DRM.
"I also remember some forms of DRM will even include disc mastering errors/physical corruption on the actual disc and use those as a sort of fingerprint for the DRM. The copied ISO has to include them at the exact same place in the ISO as on the IRL disc and the ISO emulator has to emulate the disc drive read errors they cause."
So yeah. Never mind that I already own this goddamn game, and that it's allowed by law to make one copy for personal use, AND that intentionally breaking something is very shady indeed.. apparently I don't really own this game after all. So I went onto the almighty search engines, and instantly found a copy of this game for download. You know EA.. I wanted to play nice. You didn't let me. Still wondering why people do piracy now? Might take your top suits that suggested these fucked up DRM schemes another decade to figure out maybe.. even given the obvious now.
But hey I wouldn't even care that much if the medium these games are stored on wouldn't be so volatile (remember these discs are now close to 20 years old, and data rot sets in after 30 years or so). You company decided to publish these on CD. We've had cartridges in many forms before, those are pretty much indestructible and inherently near impossible to duplicate. And why would you want to? But CD is what you chose because you company were too cheap to go to China, get someone to make some plastic molds and put your board and a memory chip in that. Oh and don't even get me started on the working conditions for game devs.. EA and co, aren't you ashamed of yourselves? No wonder that people hate game development houses so much.
Yay, almost finished downloading that copy of Medal of Honor! Whatever you say EA.. I've done everything I could to do it legally. You are the ones who fucked it up.9 -

So I installed a new Linux distro, and since the DE is Gnome, I wanted to spice things up with a Conky file.
I download my conky theme, extract it, and try to run it.
And it's broken.
Apparently, the Conky development team decided it would be a great idea to switch over to an ENTIRELY FUCKING NEW SYNTAX, LEAVING EVERY CONKY THEME WRITTEN BEFORE AUTUMN THIS YEAR USELESS
Oh, no biggie, I think. After all, the development did very graciously publish a Lua file to convert old conky configs to the new syntax.
Except no.
The file used to convert conky configs uses the old loadstring function, for which support was dropped in Lua 5.4
So not only did Conky make every config written earlier than this Autumn obsolete, the FUCKING TOOL THEY DEVELOPED TO HELP WITH THAT IS ALSO FUCKING BROKEN
Fuck Conky. I wasted 2 hours screwing with this broken-ass piece of shit3 -
Starting game modding on Garry's Mod 9 back in 2006. I was 14. I never thought it would turn into my career. Also I miss writing Lua3
-
I was looking for alternatives of MC that are atleast usable, and found a thing called Minetest. This apparently is a Voxel Engine/Scriptable game, where you create games, that consist of mods/modules and other resources.
The cool part of it is, that mods and games etc. get handled by the game itself in a package manager type fashion, so the only thing you as a user have to do is selecting them in the ui, and putting them into your world.
It's this easy because the content is managed by a content database. This engine is built with multiplayer support by default.
Now comes the interesting part: apparently a few devs sat together and made a whole MC clone in this engine, and have called it Mineclone 2. I was testing it recently on a server and have to say, that it doesn't appear to be some low effort clone, but to my surprise is an actual playable and nicely looking game. So far i'm having fun with playing and even modding it.
Since the core is written in C++ and the mods and games content is written in LUA, you can easily writte new stuff for it, and even look at other mods stuff, to find out how to make it compatible or how to do certain things. The licenses usually allows to reuse and redistribute.
If you're looking for something like that, give Minetest + Mineclone2 a spin.4 -
After opening game files for Ragnarok Online and saw the quest files are human readable (lua or other scripting language). Had some Flash workshops to confirm my interest.
Later in college, I make games for every lecture projects (with my friends). Now our game studio is 7 years old.2 -
So LUA injector to Payday 2 requires on Linux certain library (libcurl3). So you know, sudo apt install libcurl3 and there you go!
You would think.
Apparently while you do that, the installation of libcurl3, it completely nukes your Steam installation... For some reason.
Can some please explain me, what the hell just happened? Please?1 -
Everyone I tell this to, thinks it’s cutting edge, but I see it as a stitched together mess. Regardless:
A micro-service based application that stages machine learning tasks, and is meant to be deployed on 4+ machines. Running with two message queues at its heart and several workers, each worker configured to run optimally for either heavy cpu or gpu tasks.
The technology stack includes rabbitmq, Redis, Postgres, tensorflow, torch and the services are written in nodejs, lua and python. All packaged as a Kubernetes application.
Worked on this for 9 months now. I was the only constant on the project, and the architecture design has been basically re-engineered by myself. Since the last guy underestimated the ask.2 -
Rant portion:
Fuck me, there's not a ton of great resources for Lua. I have the book, and it's actually fucking incredible, but as soon as I have a question which I would usually Google, either it's a SO question that almost hits the mark (but absolutely does not answer my initial question) or a mailing list that DOES answer my question but holy FUCK it's difficult to read!
I 100% recommend the Lua book, though. It's remarkably helpful and covers just about every little detail of the language and it's corresponding c API, and even some of how Lua works behind the scenes.
Non-rant portion:
Finished up the first version of my library and now I'm binding it to Lua and this time around I'm using all the best practices including setting and checking metatables so that Lua can't segfault. It's going great, I properly learned about the Lua stack, and I feel good. Cross-platform double-buffered command line via a scripting language... What a way to enter 2020. Everything went so smooth that I got to 3am before I realized what even happened.1 -
I think mine had to be when I was working with SQL and Lua. I was attempting to store some ints into the database but kept having it fail randomly. It was a 50/50 chance that it would succeed or fail. I tried reading errors (Limited on what I could see) after a while (Almost 3 days, since everything I could think of didn’t have issues and was completely lost) I realized the system another developer setup returned either string or int, thus it causing it to error out when I gave it a string. Once I added a tonumber statement, all my headaches went away.

Can gamedevelopers stop using lua as their freaking scripting language..
Every time I try and figure out how tables work and think I finally get it it throws a big fuck you curve ball.
Oh and then they use json file to store the data of a table except that those json interfaces are complete retards.
If you are going to support json files then why the fuck won't you put in a small fucking inconsecential JS interperter so you can actually find some docs regarding more complex fucking docs then those simple minded t[guildName] = "guild"
Another thing, why the fuck does lua not use {} like every other langauge. I use those curly brackets to figure out where shit start and ends half the freaking time.
Fuck this I'm out for today...
And a big fuck you with both middle fingers to any dev that thinks lua is a great scripting language for plugins.3 -
Sitting in my beautiful chalet on this beautiful park. My garden nicely mowed. Sun in shining. Was in the zone the whole day. Now it's time to shift some gears and fetch some desperado's (will pass out after three probably, didn't drink for long time). Walk towards neighbor and drink together.
Life can be so beautiful14 -
I have always been interested in computers. when I was in second grade, I decided I was no good at electronic circuits, and decided I wanted to program instead. My dad told be to check out free basic, and I immediately downloaded FBIDE, and followed tutorial videos on YouTube. once I finished the videos, I started to write mad libs programs. I made various types of calculators, etc. and loved it, so later I learned a bit of VB. I messed with that a bit, but didn't like it too much, and started web developing. The moment I saw some JS code, it was like an instinctive second language to me. I learned js and started making some ugly, but cool interactive web pages. When computercraft came out for minecraft, I learned lua and got a deeper understanding of programming. Now, I am using node to build a personal-use IoT server and currently making a drone flight program using a raspberry pi3

LUA... its great! I love it... but WHY THE FUCK DOESNT LUA START COUNTING FROM FUCKING 0!!! WHY THE FUCK DOES IT START FROM 1! I SEARCHED HALF A FUCKING HOUR IN MY CODE AND IT JUST DIDNT WORK! then it hit me... LUA IS THE ONLY FUCKING LANGUAGE THAT STARTS FROM 1 and sure enough... after changes and testing IT FUCKING WORKED!

Lua users, have you used moonscript?
It's a little language that has it's own interpreter or can be compiled down to Lua and it's absolutely lovely (currently using it with Love2d).
Of course, as with most things, what I love about it also royally pisses me off sometimes.
For starters local has to be declared for variables, unlike lua.
Otherwise the variable goes to _
Also note, that some tutorials literally tell you the opposite.
all variables are local by default
unless you don't declare them
then they go to _ (throwaway)
Some tutorials get this wrong too.
all variables have to be declared local
except tables. failure to declare a table WITHOUT a local will cause things like
table.insert to fail with "nil" values for no god damn reason.
No tutorial I could find mentioned this.
Did you know we call methods with '\'?
By the way, we call methods with '\'.
Why? Who the fuck knows.
Does make writing web routes more natural though.
Variables in the parameters of new are declared and bound for you. Would have loved to know this before hand instead of trying
to bind to them like a fucking idiot.
Fat arrows are used to pass in self for methods.
Unless you're calling a method. Then you use backwards slash. This fact is unhelpful when you're a beginner and dealing with the differences between the *other* arrow, the backslash, the fat arrow, and the fact that functions can be called with or WITHOUT parenthesis.
And on that note..
While learning all this other shit, don't forget parenthesis are optional!
Except when they're not!
..Like when you have a function call among your arguments and have to disambiguate which args belong to the outer call and to the inner call! Why not just be fucking consistent?
But on the plus size, ":" is now used for what it should have been used for in the fucking beginning: binding values to keys.
And on the downside, it's in a language thats built on top of another language that uses it for fucking *method calls*, a completely
different fucking usage.
And better still, to add to that brainfuckery thats lost in the mental translational noise like static on a fucking dialup modem, you define methods with the fat arrow. Wait, was that the single arrow or fat one? Yeah the fat one. Fuck. But not before you do THIS shit..
someShit: =>
yeah, you STILL include the god damn colon just so when you're coming from lua you can do a mental double take. "Why am I passing self twice? Oh right, because fuck me, I decided to use moonscript." It's consistent on that front but it also pisses me off.
A lot of these are actually quality of life improvements disguised as gotchas, but when you're two beers in to a 30 minute headscratcher it sure doesn't fucking feel like it.
Nevertheless, once I moved beyond the gotchas, it was like night and day. Sure moonscripts takes a giant steaming dump all over the lua output, like a schizophrenic alcoholic athena from the head of zeus, but god damn, when it works it just WORKS.
Locals that act like locals? Check.
Sane OOP? Check.
Classes, constructors, easy access to class methods, iterators? Check, check, check, check, check.
I fucking hate ceremony. Configuration over convention is for cunts. And moonscript goes a long ways toward making lua less cunty.
If you've ever felt this way while using lua, please, give moonscript a try.
You'll regret it, but in a good way!6 -
Best/Worst dev experience 2017:
Well I started my DevRant-Stats site and got my RandomQuote bot up and running again (although the quotes aren't as good as before)
I also started a little company with my friend and made some sites for clients.
I reached #13 on Sololearn in Austria! Kinda proud of it.
I learned Lua and Ruby which are one my favorite languages now!
And as always I started some side projects that I've never finished...
Don't remember everything I experienced in 2017 but these are some I won't forget.2 -
I've ranted about this before, but here we go again:
Go Plugins.
I was racking my brains trying to figure out how one could possibly implement plugins easily in Go.
I had a look at using RPC, which requires far to much boilerplate to be realistic. I looked at using Lua, but there doesn't seem to be a straight forward way of using it. I was even about to go with using WASM (yes, WASM). But then I came across Yaegi ("Yet another elegant Go interpreter", you heard right: "interpreter"), Yaegi is also very easy to use.
There are a few issues (including some I haven't solved yet), including flexibility (multiple types of plugins), module support, etc. Fortunately, Traefik just released their plugin system which is based on Yaegi (same company), and I got to learn a few tricks from them.
Here's how module loading works: The developer vendors their dependencies and pushes them to a repo. The user downloads the repo as a zip and saves it to the plugins folder. I hash the zip, unzip it to a cache, and set the the GOPATH for the interpreter to be that extracted folder. I then load the module (which is defined by a config file in the folder), and save it for later. This is the relatively easy part.
The hard part is allowing for different types of plugins. It looks easy, but Go has a strict typing system, makes things complicated. I'm in the process of solving this problem, and so far it should go like this: Check that the plugin fits an arbitrary interface, and if it does, we're good the go. I will just have to apply the returned plugin to that interface. I don't like this method for a few reasons, but hopefully with generics it will become a bit more clean.1 -
Everything startest with HTML. I got an awesome book about HTML/CSS and I just started learning and trying out some stuff. At the beginning I got a lot of help from my father but soon I created my own websites! I setup a free webserver and after some time, I met PHP. I made tons of stuff with PHP :)
After about 1 year of creating things with PHP, I learned Javascript. And with Javascript I got into game development. I created some games but I wanted more. So I tried Unity Engine. But... well... It was hard. Then I tried Godot Engine and I finally found a game engine wich I enjoy!
I created a lot of games.
Then in 2016 I met Lua, wich is my favourite language now! (But I didn't do much with it)
Later I also met Node.js but I'm still learning :)1 -
At some point I was watching a sethbling video about programming mining turtles in a Minecraft mod called computer craft, which uses a reimplementation of lua with some mod specific functions. This inspired me to learn lua, then as I got bored with that I started moving through different languages until I settled on primarily kotlin and rust1
-
Does anyone know any good resources for learning Lua?
(And possibly how to use it with games by Valve (e.g. TF2, GMod, CS:GO)?)2 -
I hate dual boot, it might seem strange, but those 13 seconds it takes to shut down the pc, turn it on, select linux on grub (well, Windows broke my grub, so I actually have to use a modified version made to avoid windows 10 trying to make my computer "not mine") and type my password are the reason I'm starting to get lazy...
And there's more! The time between the on button press and the moment I can start working on linux is something between 3 and 4 seconds, not too much, and it takes less yhan 2 seconds to shutdown, it's not a problem, on the other hand, windows takes 20 seconds to boot, and after typing my account details, I have to wait almost 5 minutes before I can play (285 second onaverage)...
Sooooooo... Garbagedos is there only for games, I don't have any tool but notepad++ (hate it) and a lua ide for modding, I'd like to format everything and make a gpu passthrough, but I have an i5 quadcore, I don't know if that's enough 😥1 -
my old game had this flow every time a client places an object:
Client A creates a new generic object, and attaches texture paths (yep, global paths are allowed), and... lua code as strings to it.
Client A sends the entire object list to the server
Server receives it, replaces it's own object list
Server copies the entire object list and sends it to all clients
Client A and Client B both receive the object list and replace their versions.
All clients see that the object contains some code as strings
They compile and store it, and then run every frame. UNSANDBOXED.
any client could make all other ones execute any code and i was proud of my idea! -

v0.0005a (alpha)
- class support added to lua thanks to yonaba.
- rkUIs class created
- new panel class
- added drawing code for panel
- fixed bug where some sides of the UI's border were failing to drawing (line rendering quark)
v0.0014a (alpha) 11.30.2023 (~2 hours)
- successfully retrieving basic data from save folder, load text into lua from files
- added 'props' property to Entity class
- added a props table to control what gets serialized and what doesn't
- added a save() base method for instances (has to be overridden to be useful beyond the basics)
- moved the lume.serialize() call into the :save() method on the base entity class itself
- serialized and successfully saved an entities property table.
- fixed deserializion bugs involving wrong indexes (savedata[1] not savedata[2])
- moved deserialization from temp code, into line loading loop itself (assuming each item is on one line)
- deser'd test data, and init()'d new player Entity using the freshly-loaded data, and displayed the entity sprite
All in all not a bad session. Understanding filing handling and how to interact with the directory system was the biggest hurdle I was worried about for building my tools.
Next steps will be defining some basic UI elements (with overridable draw code), and then loading and initializing the UI from lua or json.
New projects can be set as subfolders folders in appdata, using 'Setidentity("appname/projectname") to keep things clean.
I'm not even dreading writing basic syntax highlighting!
Idea is to dogfood the whole process. UI is in-engine rendered just like you might see with godot, unity, or gamemaker, that way I have maximum flexibility to style it the way I want. I'm familiar enough with constructing from polygons, on top of stenciling, on top of nine-slicing, on top of existing tweening and special effects, that I can achieve exactly what I want.
Idea is to build a really well managed asset pipeline. Stencyl, as 'crappy' as it appeared, and 'for education' was a master class in how to do things the correct way, it was just horribly bloated while doing it.
Logical tilesets that you import, can rearrange through drag-n-drop, assign custom tile shapes to, physics materials, collisions groups, name, add tag data to, all in one editor? Yes please.
Every other 2D editor is basic-bitch, has you importing images, and at most generates different scales and does the slicing for you.
Code editor? Everything behavior was in a component, with custom fields. All your code goes into a list of events, which you can toggle on and off with a proper toggle button, so you can explicitly experiment, instead of commenting shit out (yes git is better, but we're talking solo amateurs here, they're not gonna be using git out the gate unless they already know what they're doing).
Components all have an image assignable to identify them, along with a description field, and they're arranged in a 2d grid for easy browsing, copying, modifying.
The physics shape editor, the animation editor, the map editor, all of it was so bare bones and yet had things others didn't.
I want that, except without the historic ties to flash, without the overhead of java, and with sexier fucking in-engine rendering of the UI and support for modding and in-engine custom tools.
Not really doing it for anyone except myself, and doubt I'll get very far, but since I dropped looking for easy solutions, I've just been powering through all the areas I don't understand and doing the work.
I rediscovered my love of programming after 3-4 years of learning to hate it, and things are looking up.2 -

My work product: Or why I learned to get twitchy around Java...
I maintain a Java based test system, that tests a raster image processor. The client is a Java swing project that contains CORBA bindings to the internal API of the raster image processor. It also has custom written UI elements and duplicated functionality that became available in later versions of Java, but because some of the third party tools we use don't work with later versions of Java for some reason, it's not possible to upgrade Java to gain things as simple as recursive directory deletion, yes the version of Java we have to use does not support something as simple as that and custom code had to be written to support it.
Because of the requirement to build the API bindings along with the client the whole application must be built with the raster image processor build chain, which is a heavily customised jam build system. So an ant task calls out to execute a jam task and jam does about 90% of the heavy lifting.
In addition to the Java code there's code for interpreting PostScript files, as these can be used to alter the behaviour of the raster image processor during testing.
As if that weren't enough, there's a beanshell interface to allow users to script the test system, but none of the users know Java well enough to feel confident writing interpreted Java scripts (and that's too close to JavaScript for my comfort). I once tried swapping this out for the Rhino JavaScript interpreter and got all the verbal support in the world but no developer time to design an API that'd work for all the departments.
The server isn't much better though. It's a tomcat based application that was written by someone who had never built a tomcat application before, or any web application for that matter and uses raw SQL strings instead of an orm, it doesn't use MVC in any way, and insane amount of functionality is dumped into the jsp files.
It too interacts with a raster image processor to create difference masks of the output, running PostScript as needed. It spawns off multiple threads and can spend days processing hundreds of gigabytes of image output (depending on the size of the tests).
We're stuck on Tomcat seven because we can't upgrade beyond Java 6, which brings a whole manner of security issues, but that eager little Java updated will break the tool chain if it gets its way.
Between these two components we have the Java RMI server (sometimes) working to help generate image data on the client side before all images are pulled across a UNC network path onto the server that processes test jobs (in PDF format), by reading into the xref table of said PDF, finding the embedded image data (for our server consumed test files are just flate encoded TIFF files wrapped around just enough PDF to make them valid) and uses a tool to create a difference mask of two images.
This tool is very error prone, it can't difference images of different sizes, colour spaces, orientations or pixel depths, but it's the best we have.
The tool is installed in both the client and server if the client can generate images it'll query from the server which ones it needs to and if it can't the server will use the tool itself.
Our shells have custom profiles for linking to a whole manner of third party tools and libraries, including a link to visual studio 2005 (more indirectly related build dependencies), the whole profile has to ensure that absolutely no operating system pollution gets into the shell, most of our apps are installed in our home directories and we have to ensure our paths are correct for every single application we add.
And... Fucking and!
Most of the tools are stored as source bundles in a version control system... Not got or mercurial, not perforce or svn, not even CVS... They use a custom built version control system that is built on top of RCS, it keeps a central database of locked files (using soft and hard locks along with write protecting the files in the file system) to ensure users can't get merge conflicts by preventing other users from writing to the files at all.
Branching is heavy weight and can take the best part of a day to create a new branch and populate the history.
Gathering the tools alone to build the Dev environment to build my project takes the best part of a week.
What should be a joy come hardware refresh year becomes a curse ("Well fuck, now I loose a week spending it setting up the Dev environment on ANOTHER machine").
Needless to say, I enjoy NOT working with Java. A lot of this isn't Javas fault, but there's a lot of things that Java (specifically the Java 6 version we're stuck on) does not make easy.
This is why I prefer to build my web apps in python or node, hell, I'd even take Lua... Just... Compiling web pages into executable Java classes, why? I mean I understand the implementation of how this happens, but why did my predecessor have to choose this? Why?2 -
Holy shit, what a language...
I'm currently learning Java right, I have never seen such a weird language in my life.
My background is Web Developing and some lua here and there. After a while playing around with Kivy and other alternatives to native Android Studio development I decided it was most probably time for me to start actually getting ready for the inevitable Android Studio.
Getting used to the GUI was easy, everything seemed to make sense and I was already used to IntelliJ.
But the issue came from Java, the number of ways that it's broken, just JVM by itself should be enough to condemn this language to eternal doom. Not even talking about the Syntax, coming from JS it was basically Hell.
I get it's more than useful, but seeing its History, Java should've probably stayed at its Oak stage lmao.27 -
Any opions/experience with Lua? Im using this language right now in my internship. Its suprisingly easy, but not as popular as javascript or c#.8
-
With a background of predominantly C style languages and Lua, it's quite refreshing to be able to jump into Python and feel comfortable in it's usage. I've been running through some exercises (https://www.practicepython.org/) and am having a pretty jolly time with it.
Just wanted to share that I'm having a great day so far, and that I hope you do too! :D -
Got VS running, SDL up and running and outputting, and angelscript included. Only getting linker errors on angel at the moment, not on inclusion, but on calling engine initialization.
Who knows what it is. Devs recommended precompiling but I wanted to compile with the project rather than as a dll (maybe I'm doing something stupid though, too new to know).
Goal is to do for sdl, cpp, and angelscript, what LOVE2d did for lua. Maybe half baked, and more just an experiment to learn and see if I can.
Would be cool to script in cpp without having to fuck with compilers and IDEs.
As simple as 1. write c++, 2. script is compiled on load, 3. have immediate access to sdl in the same language that the documentation and core bindings are written for.
Maybe make something a little more batteries-included than what lua and love offer out of the box, barebones editors and tooling and the like, but thats off in the near future and just a notion rather than a solid plan.
Needed to take a break from coding my game and here I am..experimenting with more code.
Something is wrong with me.8 -
I started in Lua in a program called AMS (it made autorun programs but has full scripting support making it pretty powerful) making little software applications.
That evolved into PHP and shortly after JS, HTML and CSS.
After a while i added other languages and it continues to grow today.
The UI aspect has just been something i have always had an eye for. -
Couldn't be arsed with all the conditional compilation that angelscript required, so I dumped right back to good ol' lua for now.
Got lua in, vm started, loading strings and pushing/popping the stack.
Got SDL actually drawing as intended.
I don't know even half of what I'm doing.
Apparently header files that end in ".hpp" are specific to c++, while .h are for c headers.
I like the new SDL2 though, little bit different than SDL1. Not a lot of tutorials cover the difference, but I could kinda suss out from the documentation where I needed to adapt, even though I'm still pretty loose on the library, on the docs, and on c++ itself.
Still just a learning project.
Also, I'm continually surprised there isn't a portable, platform independent tool or little language just for replacing all pseudo-languages out there like .bat and .sh, and .zsh
Maybe even just a tool that standardizes it all, then takes config files that map the new standard to system dependant commands, so you can download the damn thing, configure the relevant environment variables, drop in the platform dependent configuration (or your browser or package tool detects what platform you are on and chooses the relevant package/download for your platform), write a console script and the tool automatically translates, and emits the system-relevant commands to that platform's console (so you don't even need much platform-specific code to do things like file access). -
I want to learn a scripting language, and can't decide which one.
Python, Ruby, Lua, something completely different ?
I want to hear your opinions.11 -
My first programming lan was Lua. And they who know that lan knows, that I may was confused when I switched to a 'normal' programming lan like c# or java, because when you init a string you just type: a = ":)". but you can still set it to an int: a = 10. So every vars in Lua aren't sticked to a type. The arrays also can have any kind of var in it.
So I never learned what a String, int, ... is. I didn't understood why a method can't just return anything or why an array has a length.1 -
I have lost track of the whys, but I'm writing something that loads a datastructure not unlike specifications of C types (plus struct single inheritance and generics) from any DLL-s tossed in the same folder, then organizes them into a pretty database. Now I just gotta keep gradually broadening the scope until I get to the feature set of the modern C# type system.rant what is this not gonna halt another project at least i can show off my mathz i could've went with lua i really should stop writing in the tag row why

In highschool I started by setting up an open tibia (OT) server for which I copied and edited lua scripts to create spells and quests. Didn't do anything remotely difficult in those times.
In university I needed to learn and use Prolog. And soon after that I had an OOP course in Java. Didn't really learn Java during that course. And started to accept I would never like real programming.
During a Datastructures course I actually got the hang of java and started to program in my spare time.
Finished the Datastructures course with a good grade which landed me a job as student assistant for a python course.
That job in turn landed me a part-time job as python developer where I learned most of my programming skills.
Now I'm back to working in Java and I still learn everyday. -
Lua and its goddamn metatables. I love the crap out of lua and its syntax, and metatables are really important, but setting them up is unbelievably confusing.1
-
First contact with code was about 10 years ago, trying to customize my own server of the old Tibia (pre historic mmo game) with lua language

What programming books do you all recommend?
Language wise any books on C, GoLang, Python, Rust, and LUA are welcome
And topic wise I’m interested in books about computer science theory, network programming, low level programming, and backend programming are welcome.
I know it’s a wide variety of topics but some are stuff Im currently doing, I’ve already messed with and just really want to learn more or focus on, or plan to do it when I get around to it6 -
In 2011,when i was 12, i was playing Garry's Mod with a couple of friends, and i don't remember the circunstance, but one of my friends said: "I wonder how games i made". I have no idea why i was never curious about this subject before,since i played A LOT of videogames, but this question did stick to my mind, so i decided that i would search about it. Searching, i discovered that Garry's Mod used the Source engine, and that it was made in LUA. Tried LUA. Understood very little. Lost my interest. And then, i would only attempt to program again back in 2015, where i learned C++ in high school. Then i learned SQL, and now learning Java. I also discovered that i LOVE programming, and now i have plans to graduate on CS.

Skein: noun - a type of access modifier, allowing a property to be read internally or externally, but only written to *externally*. See "orwell" for opposite access modifier.
hermit (noun) - an access modifier specifying a property may only be written or read internally.
Gopher (noun) - an access modifier not to be confused with a groundhog.
Blackhole (noun) - can be written to, can never be read. See dev/null for details.

Is Lua worth learning?
What can be achieved easily with it? What are it's strengths and weaknesses?6 -
I got admitted into University a few weeks back, unfortunately Universities in my country dose not allow students to take CSE unless they have maths and physics in their A levels even though I had computer science in my A levels and did a lot better than my friends who had maths and physics. I asked them if there was any way I could change my major and they said no. So unfortunately i have to study management information system now and that's the closest subject i could find related to computers the i was allowed. I envied all the students I met there since all of them were studying computer science and they didn't even know how to code . These are the very students who change their major from CSE to BBA . The education system in my country is fucked up ;-; . But that isn't going to stop me from coding right now I started learning java and after I'm done with that i plan on starting to learn lua. Anyways I'm planning on giving another A levels on maths which I'm really bad at lol. Also I don't really know much about management information system i just went with it because all the other BBA majors seemed boring to me and I was too bummed out to research on the subject.Anyways wanted to ask if it is possible to get a job as a developer if you're self taught in South Asian countries?7

The absolute worst experience i have ever had with a dev technology was a mixture between notepad, pgeLua and a PSP.
Back in 2010, i coded a game called "ReapeR ValleY" for PSP (homebrew). I had no idea what an ide was and i have never really coded before that.
That resulted in a 1500+ line code that in a single file written in notepad. The performance was horrible since it just ran through the same lines of code over and over again with arrays filling up and flowing over with data.
The entire game was written in pgeLua (a supposedly more game friendly version of Lua) and ran on the PSP.
The PSP needed to be overclocked in order to run the Game smoothly. I had to restart the entire PSP when the game crashed and i already installed a custom bootscreen that basically shortened the time to boot.
You can still find the game online hosted on various websites. It was my very first and unexperienced attempt at coding, but it worked.
Moral of the story: you can code with just about anything, but when you don't inform yourself about IDEs, frameworks and such, it might be painful.
... also Notepad is pure brain pain to code in. -
The Love2D documentation is so lovely to read, this has been my favourite experience learning a language.1

I'm trying to pick up game development as a hobby (im already a full stack software engineer) and ive decided to either do lua with roblox or java with minecraft. im going to start out doing mods and building on top of already existant systems and then venture further if i like it. which do you think i should do? lua or java?5

It was game dev.
Just googled how to make games on my own, thats how it began. Yoyo games game maker, Oracle's greenfoot(this was some cool shit),stencyl then using some random game engines, pygame,lua etc. Had fun. Still having fun. Will try game dev again in future.2 -
I started with programming through a Minecraft mod called Computercraft. You programmed a computer with lua. Some time later I played with python, and then I was hooked. I am a self taught programmer and have tried many different languages since.

LUA is used in Starbound, WoW, in Half Life mods...
I learn Lua making mods for Starbound.

Welcome to the first (and probably only) episode of Code’s Papercuts!
I don’t like Lua. I have almost no experience with it, but in my opinion any programming language where arrays start at 1 should be ashamed of itself.
This has been ~~Brady’s~~ Code’s Papercuts!2 -
Started with the old computer craft mod for Minecraft that put Lua into a form I could understand with clear goals (I was 12 or 13 at the time), and from there learned Java and some web dev tools. Now I'm here writing simple compilers to procrastinate uni work

Hi everyone well we quit gg scripting cause we figured out lua can be converted to cpp for memory searches! we all know lua and know how to convert it to cpp but for the gui
How do i learn java?8 -
There needs to be a new (MOOC) class for people like me.
Hi, I'm William. I can't get my head around designing systems. I've read GoF and a few breakdowns of it as well. I find some patterns obvious for my field of interest (game dev, woot!) while I'm reading through the stuff, but have a pretty hard time retaining much of it. I'm aware of the danger of over using patterns, so I don't worry that much about it. I'll look something up when I'm sure I need it.
Still, I'm tired of the tutorial blues. I can watch a few different people write entire games, usually not in the language of choice, but that only helps me so much.
How do I fight scope creep? In the meantime, how can I make things extensible? Scope does need to creep some, after all.
People joke about starting with (visual) BASIC ruining you forever. I don't believe in that crap, but is this just denial? Am I too dumb for this? Not that I'd ever seriously blame a language for that.
I've been a hobbyist for well over 10 years, please don't make me count exactly how long I've been unsuccessful.
I'm baffled by Löve. I think it's the coolest shit I've seen, maybe ever (unless we're counting IPFS).
I think what really prompted this rant, apart from the obvious degradation of my mental health, was my search for an entity component system for Löve/Lua. Hold your replies. I know there's a few of them, and I'm positive that they're fantastic. I'd roll my own, but that requires actual Lua specific knowledge that I just haven't dug all that deep into yet. I can't wrap my head around the ones that exist, even though I can tell their complexity is next to none really.
I have severe tool anxiety, I'm shocked that I've stuck with ZeroBrane Studio as long as I have. It feels good though.
Sorry to use this as "Devs Anonymous", but I think that's how this community helps (me) best.
I feel like I should stop now and just say: Advice? before this gets much deeper/less readable. -
I am learning Lua because I am developing in a game. My question is would there be a way to load C into Lua6

I've been doing stuff on my free time after school for about 3 years now. And i cant keep working on projects without losing motivation or getting stuck without a solution and then giving up, i've also tried working with a lot of teams and friends but it seems like everything i do or i work on ends up cancelled or full of issues and roadblocks. any advice?4

Today after the week and a lesson time in an high-school I got back home and decided to play some sacred 2
I had already installed some mods on it given that I have already finished it years ago and I wanted some challenge.
It ends up that the mods add too much difficulty, so I open up the configuration files of the mod (some sort of Lua tables) and then spend like an hour and half doing some reverse engineering on it to find a middle way between the vanilla and the Uber difficult mod
Wow! -
I have a class on my college on which we can choose what to do as a final project the only requisite being that we need to do something we haven't covered in any class at the degree.
I want to be a Gameplay programmer and saw that many offers ask for Lua, then I think this is an opportunity to do something in Lua and learn the basics but I don't know what to do, any ideas of a simple project I can do in Lua or a framework that uses Lua that can teach me the basics of it?
Tl;Dr: Want to do a small project in Lua, have no idea what to do tho. Ideas?4 -
Have i told You i hate lua and lohrawan with a node Red Copy to? And anyway IOT also. Grgrgrgr. And i hate Autokorrektur now3

Was playing some devast.io and it was awesome

I had a high score around 1000k or so kept being killed constantly and such on downloaded pycharm on mom's pc, downloaded an android emulator as well :) i cant wait to go back to scripting but andlua is just a mix of java and lua
Example: https://youtube.com/watch/...
what do ya think about the high score? -
I started with a free trial of neobook (anyone remember that?), and then moved on to MS SmallBasic. At some point I had discovered Roblox and was stuck with that and lua for a few years. Eventually I started learning C# from a course, but never really used it much so I kinda forgot it.
School got a lot more busy for me and so I wasn't really able to do much programming for a few years, and even when I did, it was mostly bash and docker stuff. Then in the beginning of last year, I was able to start learning Go, which is now my current language of choice. -
WOW -__- they left me to code the SPO Teams website when im coding a Text rpg engine while Over clocked is fixing his tablet while Solario is helping his other friends code his java + lua = andlua mod menus for android Screw ya )=<
@overclockedgd
@Solario360
im not even good at website designs LOL its gonna be a website that wants to commit DDoS iill post the final product and if you survive through the whole website without getting your computer molested props to you =)14 -
man that whole lua shit from neovim really went overboard
like seriously, that shit used to be for msgpack/RPC and they've literary made it default then built-in and now the whole fucking remote protocol's silently rotting 🪰 away...
A software fuckup so massive the fucking editor now needs 2 running instances so their "lua kink" can keep going.
No wonder fucking denops was born

only thing keeping me there's tree sitter but once that gets inside vim/vim it's byebye fuckers2 -
Lua handles arrays and maps/dictionaries essentially the same way. Makes for a pain when binding to cpp. Shame in an otherwise awesome embedded lang
-
Tried Lua for the first time in a while. Really didn't like how it handled chars/strings, that's about it.3

Dabbled in primary school on Microsoft Front Page, but actually programming would have been the WoW private server scene. Started on C++, got confused, tried LUA, loved it, came back to C++ was still confused but could get things done. And then the story goes on and on.1

! Rant
Recently received my ESP8266 and for bad or for worse quickly flashed it to use thingsSDK and espruino.
I have setup a webserver on it but at the moment you need to go to its local ip to see the page, does any one have tryed this before and overcome to redirect all requests to that page? Any ideas are welcome, i know this can be done easly with LUA but cant code LUA, yet...13 -
Wtf is this ESP32 shit and it's hype?
I bought one because I thought JS on a microcontroller? That's gotta be fun!
I'm a hobbiest when it comes to MCUs and I do JS as a job, so I tought I'm made for this and I know at least as much as all the kids on the internet doing it.
Nothing makes sense with this shit. You have to flash wildly compiled modules of WHATEVERTHEFUCK with fucken python development-kits which have something to do with Lua to give you some kind of node-REPL which answers you with a bunch of strangely-looking errors starting with "stdin:x:".
If this NODE-MCU shit is made for JS why is there stuff about Lua everywhere you go with this, I don't get a single thing. Now I'm sitting on about 3 different git repos of sdks or what do I know and know less than before.
Oh and there is actually not a single tutorial really targetting the esp32. it's all about that 82xx-model.
Then I start googling around a bit more - It's not even ES6, it's just some ES3/5 shit. Why would you even do this. That's actually harder to manage than classic C/C++. You get no gain with it. Fuck me.
Wtf bro.23 -
Why is Lua such a pain to install? Like seriously there are so many hoops to jump through, why can't it be like java or python? -_-3

Looking for Starbound modding LUA examples
Download unofficial modding book and found out json examples...1 -
Has anyone used or seen a nice lua back end wrapped already in a windows front end programming platform, I have made many apps do many things in a app called AutoPlayMediaStudios, even tho it was made for AutoPlay Menus at first the tools it as and can make are epic but it's getting past it and the support is bad for $300 you get the app at that time and 6 months support and update after that you get NO updates and no real support.
I looking to move forward,there is the option to learn a new language for most people but for me I do it for fun and I just want to be able to keep supporting the tools I already made but in a more updated platform and better windows integration.
I love lua as its 90% if not 100% readable and understandable so when I get a error I can see it easy.
Love to see what other apps might be out there, also I don't want to make overlay apps I want to make core exe's fk MS's overlay bull.
Thanks for reading.1 -
Seeing as I will be scorned for asking this on SO, and there's a ton of devs here that probably had this conundrum: how have you solved horizontal scrolling when working? I know shift + mw+/- works but what's the use having a mouse with macro functionality if not to simplify that? My current software supports lua scripting (but I don't know how to write it). I see some people requesting this while googling I but cannot find anyone that has a solution. The closest I get is a user requesting it from Logitech as they apparently have the same but for ctrl+mw in their products.10

Hi everyone hows it going today? been learning alot lately Question? when working with lib2cpp.so files whats the best inspector for them? and what do these files contain? (example: gamelib.so)
i know a .so file is C++ so i think it has something to do with offsets and memory ranges something like that.
but im trying to open one lol
we have moved to andlua and i learned the api fully

AndLua+ app is a lightweight scripting tool that allows you to easily perform script programming and testing on your Android phone. This is a very useful tool for those who need script (android development or modding) programming. AndLua+ is based on the open source project lua. It uses a simple and beautiful lua language, which simplifies cumbersome Java statements. At the same time, it supports the use of most Android APIs, free installation and debugging, and makes your development on your mobile phone easier and faster. The permission requested is for you to write a program to use, please rest assured to use. -
For fucks sake, why can't Microsoft switch to Lua or JS as an embedded language instead of VBA.
It bad enough working with their office-jank but having program in this butt-rape of a language takes the cake.8 -
Lua/ C
Java/ C
Swift/ Objective C
Visual Basic / C or something
C / C#
……..
👆last reversed yet, that looks like a funny face 😑…
Where, am I?…8 -
luasocket decided to provide blocking network primitives to be used in single threaded lua environments. Sure I can overcome it with socket select polling, promises and coroutines. But WTF. It is 2016! Even node.js does it better.
