libCat VS AECforWebAssembly

Compare libCat vs AECforWebAssembly and see what are their differences.


🐈‍⬛ A runtime for C++23 w/out libC or POSIX. Smaller binaries, only arena allocators, SIMD, stronger type safety than STL, and value-based errors! (by Cons-Cat)


A port of ArithmeticExpressionCompiler from x86 to WebAssembly, so that the programs written in the language can run in a browser. The compiler has been rewritten from JavaScript into C++. (by FlatAssembler)

  • Good languages for writing compilers in?
    8 projects | /r/ProgrammingLanguages | 11 May 2023
    Well, I have written the first compiler for my programming language, targetting x86, in IE6-compatible JavaScript, and the second compiler, targetting WebAssembly, has been written in C++11. I think that, to choose a language to write a compiler in, you need to look at at least two things:

    That could be true. I host my AEC-to-WebAssembly compiler on GitHub, GitLab and SourceForge, and it's only on GitHub that it has 21 stars and 2 forks. On GitLab and SourceForge, it has zero of both.

    Well, the main compiler for my programming language is targetting the JavaScript Virtual Machine by outputting WebAssembly. I think it's even better than targetting Java Virtual Machine, because, for one thing, your executables can run in any modern browser if you output WebAssembly. If you target Java Virtual Machine, the users need to actually download your app. Furthermore, there is an official assembler for WebAssembly called WebAssembly Binary Toolkit (WABT), so your compiler can output assembly and not have to deal with binary files. There is nothing equivalent to that for Java Virtual Machine.
  • How many lines of code does a compiler contain?
    4 projects | /r/ProgrammingLanguages | 22 Apr 2023
    Well, my AEC-to-x86 compiler contains 2'000 lines of code (click "View Source"), and the much more feature-rich AEC-to-WebAssembly compiler contains 5'500 lines of code.

    Are you really telling me it's easier to write a tokenizer in Rust than in C++? You know, like I've written a tokenizer for my programming language in C++:

    I had no idea that is a valid syntax! OK, my largest C++ program to this day is only 5'500 lines of code. If I were making larger programs, I'd probably know stuff like that.

  • Undergrad dissertation/thesis ideas relating to programming language design / compiler implementation?
    2 projects | /r/ProgrammingLanguages | 26 Mar 2023
    For my Bachelor thesis, I have implemented a PicoBlaze assembler and emulator in JavaScript. If I ever get to that point, if I do not drop out before I have to submit my Bachelor thesis (I have two courses left in my undergraduate program: "Communication Skills" and "Basics of Automatic Control", "Basics of Automatic Control" probably being the most difficult course in my undergraduate program). And, for my Master thesis, I have a compiler that compiles my programming language to WebAssembly, but I will probably not get to submitting my Master thesis.
