I like how the most difficult thing in the whole video is the lua syntax highlighting

teachers: there is not a bad question tsoding: its just a bad question 😎

BRAZIL MENTIONED? 🇧🇷🎉

to yet another Pogromming session?

Lua is a great little language. Tables as data structures work surprisingly well, closures, iterators, everything can be a key and value, ... Even module import just fits so neatly into the language, usually just returning a table (but Lua just lets you do whatever! No restrictions is really cool)

The code is actually pretty well documented with helpful comments. It really makes it easy to follow the code and get what it's doing. I'll remember this next time I cross paths with one of those clean-code advocates who defend that you should never use any comments in code.

Lua my beloved

A good reason for the app to use the vm is to test whether ALL of the functions of the VM work. Because lua isn't just an app it's value is also in the vm you can embed in literally any other app - like how the vm is embedded in this c app that interprets lua

Gotta implement this fix to the embedded Lua interpreter in my app.

Gonna take note of, Asserting dominance, when joining a new project.

You mentioned at the end you look into other open source projects from time to time. Which ones did you look into and found interesting?

Next, let's add nullptr to Rust.

Finally, arrays in Lua (tables reference)

Chat Question: "Is there a [programming] language he [=Tsoding] cannot code [in]?" (around 30:00) This is not really a question, or only a question and not what it looks like in the first place. It shows the respect of the questioner, because he is impressed of your computer programming skills. The person asking in fact implies, that there is no language (to his knowledge), that he thinks of that you couldn't possibly learn and use. This is a highly meta-level question and it lives in the context and also in a social context. That is btw. very impressive and in contrast to programming languages something that computers CAN NOT understand and possibly will never understand (Including large language models. There is no such thing as "understanding something". Thanks for the great video, Tsoding and also to Lua, that actually fixed you! Hehehe:)

Russian луна́ is not from latin, actually, it's from a common ancestor with latin, they just developed in very similar ways.

Make it a PR. They would commit a sin not accepting it.

With the complication of non-local jumps and `goto`, my first thought was to instead just transform `double` into `for i=1,2 do`, i.e. make double less a macro and more a loop so it plays nicely with the relative jumps. I probably would've done this from the start, but it's neat to see you took the code duplication approach first and found out interesting things about the byte code. (edit: I clicked post about 5 seconds before you mentioned the easy solution was to implement it as a loop, forgive me for my hubris haha)

Where can i find your emacs configuration?

I wonder if it would have been possible to backup the lexerstate and effectively run the lexer over the double body twice to get the goto statements into the internal backpatching system.

I was waiting for this for so long

I FKN LOVE THE POWER OF SIMPLICITY!!!

Welcome to a Brazilian programming language.

Is the code for emacs lua-mode longer than the actual lua interpreter?

I'm not going to say it's better, because it's really just a different way of doing things, but Vim makes it pretty easy to add keywords for highlighting. I defined null as an alias for NULL that I use in my header for every project, and I just added it to the list of keywords and it was highlighting from then on. The weird error you had when trying to compile later was that you added 'a' to the start of lua_load() at around the 41:00 mark. As for adding 0-based indexing, I'd name it Lua++ and use .lpp for the file extensions to differentiate it. And as far as using a double block, you could either convert it into a for loop that runs twice, or convert it to a while loop and use a local inner variable to determine the exit condition of the loop.

Yes Portuguese is Latin based, and Lua is our word for Moon yes. It's to note that Lua (the language) was made in Brazil where Portuguese (of the Brazilian variation (duh)) is spoken. Reading the wiki tells me that there were some trade barriers on software importation which lead to its creation, also seems that Lua was preceded by a language called SOL (Simple Object Language) but in Portuguese Sol mean Sun, so Sun and Moon.

"tylko jedno w głowie mam"... lua 5.1gram

You fixed Lua? Why? It's part of the experience!

TJ will be happy to see that the 1-based was fixed hahaha

The priority limit was first invented/discovered by Bob Floyd.

Do you know of any resources on how to write and build a website in Lua ?🙏

"luac" must be the compiler: anything ending with "c" is a compiler, in classic UNIX style. Also --help says the output is "luac.out", similar to the default output file for the C compiler (gcc still does it that way) is "a.out".

2:05:34: This is not true, the ipairs function will index raw, starting from zero. Which "user-facing-value" for a starting index is used does not matter.

U are literally the best programmer Livestreamer on yt in my opinion

Impressed. I agree, knowing & being able to follow logic is so much more important than the actual language itself. Instead of finding *int begin, end* with luaK_getlabel then looping through luaK_code, _I wonder if you can simply do_ *block(ls); block(ls);*

There should be a specification statement like in fortran to opt out of the 1 indexing of the array

...sometimes you gotta do "die Scheiße"

I feel like this is just a dumb way of doing it. Lua basically treats an array as a key value pair so you could literally just say the key is 0, 1, 2… etc instead

so by doing copy pasting, we can just add proper Table thing, like there is default Table that starts from 1 and properTable that starts with 0) no codebase in the world will be broken that way I guess

Why fix something when it can fix itself: days = {[0]="Sunday", "Monday", "Tuesday", "Wednesday", "Thursday", "Friday", "Saturday"}

Do you have plans for LuaJIT?

what if you jump *into* the double block? or even jump into a condition or a function or a loop. So basically goto is weird

Impressive, very nice. Now lets see Paul Allen's fix for Javascript.

PUC - RIO, brasil mentioned let's go!!!

no way bro just chacked lua

Hi tsoding now that you've got some Lua experience you should check out the löve framework, it's very similar to raylib in a lot of ways but focused on lua

submit the pull request

I literally though about zero indexed lua yesterday

I'm amazed at the comments in this source code.

1:05:00 man gets frustrated its hard to add new syntax highlighting to a language specifically designed to never add new syntax

when will neovim switch to hacked lua for config

I’d love to see you write an lsp for porth

55:17 i know some devs who have a very different meaning for what "high-level" is lol

Can you work on your text editor again soon :) I really enjoyed that project.

I always wonder 🤔 if you are a typical introver programmer ?

You look like you just won a brand new skateboard or something like this lol kkkkk never saw someone so happy reading code (at least until minute 49:00 lol I'm still watching)

Waited for double block inside another double block

Man... Цoding... what a guy!!!

The Roblox people went off and wrote luau-lang which is an "improved lua". Remains to be seen if it'll gain any traction.

how to join ur discord server?

This lua-mode for emacs 💀

Lua devs should add compile time parameter to tell what the first element of array should be. So that I could make game whose scripting engine starts arrays with -2 or with 5.

Lua's design is focused on embeddability, so all main does is that it prepares interpreter/bytecode VM and starts file execution.

Did Lua move to a register based machine ?

guys i think he fixed lua

I was considering doing something similar to this for my capstone and this guy just sits down and does it in 2 hours lol. Talking the whole time as well. I spent an hour just getting to understand the parser an gave up lol

can you do a tutorial of how to make a progeamming language in c++ im stuck

Thank you....

00:00 new bookmark

Can you hack into Rust and fix what’s wrong with it?

I had to translate a lot of matlab code (that is 1-indexed just like lua) into python/numpy code. Since then I have a very solid disgust against any 1-indexed language.

Next up: Fennel. :)

can you fix python and make True -> true, and False -> false

Almost 100k wtf

So… you made Lua-

> Doesn't fucking matter so that's important xDDDDD

Whenever I used Lua, I used Luajit - what about that?

What's the tool that lets Tscoding zoom in on the screen at any time? I've always wondered but can't find any info regarding it

Tsluading

Pogroming My life

And now, think of something useful to extend the language with...

Lua++ lmao

Nice

BRAZIL MENTIONED? 🇧🇷🇧🇷🇧🇷🇧🇷

Finally

Now try to fix react

Jebated. You've actually only broken things

@ 28:00 that was a gem in the rough

One of the reasons I love Lua is that the index starts at 1 😂

Lu0

That's the thing... I don't think you fixed Lua, Tsoding. Lua fixed you.

Chama no Brasil 👌

I write my neovim config in lua

So the right fix is to allow any upper and lower index bounds. Please tell me that this is the fix, because if not, there's no reason to watch.

neovim 😛

3rd!

ok now fix python

31:04 Look at this code. "chunkname" is a CONST char, and yet, few lines below its value is altered. Great job, lua devs. Lots of laught.

- "fixing lua" - ruins one of the most sensical changes in coding ever done, that, for some reason, almost NOBODY thought of beforehand
