compiler just converts High level code to machine code Even I dont remember exactly 1. Identify variables and their values tokenization making AST and so on there were 7-8 steps as far as I remember
@@markasgrazhulis9081 Well, like I said, I've just started designing it. Still deciding on the syntax, but it will probably be a JVM language since I know bytecode pretty well. I could use LLVM but that would require a bit more work since my language will probably be more high level and use a GC which JVM provides out of the box. Planning to do a hybrid of functional and imperative languages but for JVM platform. Java interop probably won't be natively (or seamlessly) supported since my language won't enforce or even probably support most of the object oriented paradigms. Should be pretty fun to develop though!
You might be surprised at how often they come in handy though. As a JS developer, I find myself needing AST pretty often for static analysis, making a codemod to make migration easy on my consuming devs, creating an eslint plugin, creating reports/manifests for projects. It's pretty niche, but not entirely crazy uncommon.
I recommend the "How to write an interpreter in Go" and "How to write a compiler in Go" books. They're really great, I'm using them right now to create my own toy language (translating the code from Go to Rust, though, since I want to get better at that).

Important: An AST does not necessarily need to be valid. The parser may detect syntax errors, but the lexer will detect further semantic errors, such as assigning a value to a read-only variable.
IVE BEEN STUCK WRITING A DANG AST FOR SO LONG!! I’m trying to write it in JS, but with high portability (so I can rewrite it in a faster language). I have a fully functioning tokenizer+lexer, but the AST generation is so confusing. would LOVE a more in depth video!! Great contents as always.
I find it most helpful to develop it together with the compiler. Neither makes any sense by itself. I am surprised there isn't more of a general standard for AST formatting though.
Before i fall asleep yesterday as a dead body, i took a deep wide breath and i wisely said to my self: The compiler is more genius than just compile your written shit. Now I know.
With the AST of a programming language one can even manage to write a compiler for JS which compiles JS to Machine Code (will be tough as JS is dynamic + WEAKLY TYPED)
That's btw exactly what JS engines like v8 in Chrome or Spidermonkey in Firefox do. It fully possible, that the JS which displays this comment was actually run in machine code.
Wouldn't mind it at all... I'd especially want to know how not to shit all of your confidence out on an interview when forget the answer to a question that's so simple a kid would know it...
Bruh i had a class in college where we've made an interpreter for mini C, like ive practically done this, but when he said that term my mind was absolutely blank
If you do a language building tutorial, could you please do one that included curly braces?? all the existing tutorials are basically lisp-syntax languages that don’t help much.
You big time need to put a de-esser on your voice. It would sometimes be a preset inside of a regular compressor. Just tweak around the frequency knob to detect your harsh "s" or adjust the threshold.
For those wondering it’s much easier to write a grammar using tools which generate abstract code for parsing the AST. Tools like Antlr are the way to go for yet another DSL.
Not a CS major, one of my pain is people talking about "runtime" code vs "compile time" code, I look up the word and seem to understand in a vacuum, but once people use those words in a sentence, I just feel they mean different than what I modelled in my mind, do you care to make a video about it? Thanks.
I would love a video/tutorial explaining how a compiler works.
Maybe even teaching how to make our own programming language.
there're a like a ton of books and university semester courses on this subject, a video tutorial would be way too long to teach you well.

If an interviewer asks me what is abstract syntax tree. I would ask myself what did I apply for?
abstract syntax gardening probably

underrated comment
only used an AST once, that was to draw text with markdown-like formatting support in html5 canvas.
You could be working on a framework, a Domain language, a RESTful API or even GraphQL. Syntax tree are pretty common. An extremly useful.
Fun fact:
"Ast" is the german word for tree branch.
Yea that confused me at first :D
lol I didn't interpret as the German ast... probably because I read the title first.?

This is the best, shortest and concise explanation that i found on the internet 😆
What a timing! My high school’s advanced placement class just started teaching about compilers and this video popped up! 😮
We need a series where you make a compiler/interpreter
Basically HTML is the true programming language.
It’s funny cause it still applies even the second time around😅😭
Flashbacks form my compiler construction class.
Important: An AST does not necessarily need to be valid. The parser may detect syntax errors, but the lexer will detect further semantic errors, such as assigning a value to a read-only variable.
Thanks bro. I’m gonna use this information and absolutely flunk my advanced programming class now

He is going deep now.
I'm working on my own programming language at the moment and it's compiled. Making a compiler is a pain in ass :')
An easy way to see what one looks like is to poke around in the internals of a GraphQL query object.
