    At university the by far coolest and most fun course was compiler construction. We had to write something which would compile a small subset of Java (Javalette) into the Java Virtual Machine instruction set.

    I wrote my compiler in Haskell because it seemed that it’d be much less hassle compared to do it in a object oriented or procedual language.

    It ain’t pretty but it’s honest work: https://github.com/jeena/CC/blob/master/Compiler.hs

      That is not a feeling I’d associate with Haskell!!

        But it definitely was, oh and when you compared the results, I don’t remember the exact number anymore but compared to especially the solutions in Java and C++ the haskell ones used around 1/10 of the lines of code to solve this particular problem. Because in the end this problem really has a recursive nature.

      I have an idea for a Rust-like language with total functional methods bouncing around in my head. Lord knows when I’ll get around to building it.

      Actually compilers are more complex than operative systems, and incredibly they are built using compilers.

        Compilers are built using compilers?

        I belive you. I made a basic OS in around a month and now i’m starting a C compiler, I think I underestimated it a bit

    When you write a compiler, you eventually have to write it twice. Once in a pre-existing language, then again in the language it compiles.

    Just say no to bootstrapping.

        Just make your own components. It’s not that hard. Tailwindcss and its cousins can handle the utility classes.
