  • Playing with DragonRuby Game Toolkit (DRGTK)
    This Ruby implementation is based on mruby and LLVM and it’s commercial software but cheap. - Source: dev.to / 2 days ago

  • Programming from Top to Bottom - Parsing
    You can never mistake type_declaration with an identifier, otherwise the program will not work. Aside from that constraint, you are free to name them whatever you like, there is no one standard, and each parser has it own naming conventions, unless you are planning to use something like LLVM. If you are interested, you can see examples of naming in different language parsers in the AST Explorer. - Source: dev.to / 3 months ago
  • Why do lifetimes need to be leaky?
    C++ compiler which compiles the Rust as if it were C++ (LLVM). Source: 5 months ago
  • Bring garbage collected programming languages efficiently to WebAssembly
    LLVM isn't a virtual machine, but WASM is. That's obviously a common misconception given the name -- LLVM was meant to be a VM early in its life, but never was, and isn't now. It's clarified in the first sentence of a home page - https://llvm.org/ It's basically a bunch of C++ libraries that implements an IR that changes over time, which help you write compilers. Curiously, I think a decade or more ago there was... - Source: Hacker News / 6 months ago

  • I want to start learning how to program DOS games
    I recommend using Open Watcom, particularly the Open Watcom V2 fork, to target 32-bit protected mode DOS, rather than 16-bit real mode. Source: almost 2 years ago
