Building a compiler in rust: Lexing & parsing arithmetic expressions (Part 1)

In this stream we have implemented a basic parser and lexer. We can transform basic arithmetic operations into an ast. Furthermore we have also implemented an ast evaluator, which can evaluate these basic operations. Overall I am pretty happy with our progress and I am looking forward to the next stream, where we will look into implementing variables.

I had taken the decision of learning Rust and during my decision making I realised that Compilers are something that can be made with Rust, I had prior interest in System Programming and OS but I had absolutely 0 idea/guidance about how to make such a complex project .THIS video is a BLESSING .Thank you

I love how you combine c like programming techniques in rust well done.

Wonderful presentation. Yes a bigger font would be nice. I'm impressed because when I was your age I had only just learned programming in BASIC and assembler in technical college. Anything like building a compiler/interpreter would have seemed way to advanced for us at the time. Now I'm getting into Rust after years of many other languages I'm looking forward to following your progress here.

Hey, which color scheme and text font are you using in this video?

Hi Julian, thanks for your video. Seems the parser cannot parse the statement 1+ 2*3 - 4 correctly, the divide expression is returned because of its precedence is smaller than multiply

can you explain why we specify a lifetime here. I am new :)
enjoying the video so far! thanks!

would you use Pest as a parser generator instead ?

this is terrible, personally i have created windows 11, and unreal engine 5 by myself. i am currently working on a new os from scratch using my own programming language.
