The perfect way to learn a new language.
Make your own documentation.

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.

LUA ARRAYS START AT 1.

I HATE MY LIFE.

Friend: You using UBLUNTOOTH?

Me: Excuse me? This is going on devRant.

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.

Network-connected train displays, failing and displaying their IP address, on a train that has WiFi on board. That's just begging to be hacked.

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'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.

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)

*College dropout (3-4 months, Computer Science - Personal Reasons)
*No prior work experience.
*Good textural communication skills, poor verbal communication skills.
*Currentally unemployed. (NEET :P)

*I have extensive personal experience with Java, and Python. Some Lua. Knowledge of data generation, parsing, Linux, Windows, Terminal(cmd & bash), & Encryption(Ciphers).
*Math, but very little algebra/geometry (though, could easily improve these).
*Work best under preasure.

Gotta love trying to sleep and waking up to a bright blue screen. Fucking Windows...

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.

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.

didn't think it'd ever happen but I had to talk a client out of having background music on their site 🙄

I have Kali Linux now, so bow down bitches.

Just had a great convo with my friend who thinks arrays start at 1. My day's going great.

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:

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.

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)."

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)

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?

Comic Sans.

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.

No boss at all 😎

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!

Should I learn C++, or C#?

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?

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.

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!

To everyone who wants a terminal editor but hates how overly complicated vim/emacs is:

Micro is like nano but with lua extensions and multiple tabs.

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!

Any lua devs here or am i index 1? (Lua jokes)

java.lang.StackOverflowError

Well, I've been betrayed... Now what?

In Lua arrays start with 1 by default. Please kill me.

she doesn't know...

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?

Who else when they're coding or get a new app, immediately Google how to change to a dark theme?

Holy fuck... Ruby has the best fucking syntax ever!

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)!

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 fuckery

I don't think you understand the word, "vacation."

Lua rocks.

You know what also rocks?

Moonscript.

Imagine python if python minus the bad parts.

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

Just spent forever trying to figure out why my POST request parameter(s) weren't working. The PHP was checking for GET parameters. Fucking hell.

Fuck starting the project, what's it going to be called?

I recently got into an argument with some people, and I want your opinion. I did a speed code in Java (just sped up clip of programming, because it looks cool lol), and someone commented:

"Way too much static abuse here. Jesus"

In which I replied:

"Actually, sir. There is near none at all, just because I use static methods does not make it static abuse. A static method belongs to the class, and is somewhat permanent. It is not a type (instance, cat, dog, animal, etc.) class, it is a Utility class, much like other dependencies you'd use are Utilities and not types."

To which they reply:

"Getting and setting is a Utility?"

Boi. If it is a static variable, yes. Like, what?

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

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.

Lua has made my life simpler! 👐

Don't work.

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 Lua

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 shit

How does random number generation work? I'm curious. What are different methods in which you can generate random numbers?

If you could link me to an article or some docs, that'd be appreciated. How far does your understanding of it go?

Thanks for your time.

Who else is a retard and does this:

String = "";

and doesn't notice the error immediately??

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.

On a website, using var something = $.parseJSON('{"with": "perfectly valid javascript in here"}') when you could just have done var something = {"native": "javascript goes here", "with": "no parsing needed"};

I hate lua .

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.

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?

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.

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!

Fuck

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.

I've been trying to sleep for a while now. Counting sheep isn't helping because now the sheep have a whiteboard and are writing down answers to fix my bugs :/

Edit: if you were wondering, there is 1 sheep as of right now

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 beautiful

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 pi

fuck this takes forever

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.

cheers mate

18 hours because I can

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!

Just spent 3 hours looking for an error in the client program. I later found out that it was a server-side error :D

k m n

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.

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 rust

So matplotlib can do 3d plots. However, when you try to then label your axes...
plt.xlabel("protocol") # ok
plt.ylabel("volume") # ok
plt.zlabel("time") # error: no such method zlabel (ಠ_ಠ)

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!
