  • it's happening!!!! damn rust programmers they are rewriting all the world in rust

    We have already re-written the Python Interpreter in rust. Javascript will be just too easy to re-write in rust, fear not for we have already re-made nodejs in rust; aka Deno.
  • how is python actually implemented?

    Quick note - CPython is the OG and most popular implementation of Python, but it is not the only implementation of Python. Some other fairly well-known examples are Jython (Java implementation), RustPython (Rust implementation), or the more mind-bending PyPy (Python implemented via Python 🤯). Python is an interpreted language, and you can think of all these different Python implementations as being different implementations of the interpreter itself. The interpreter is the program that takes your Python code and executes it via a virtual machine. This differs from a compiled language (like C) which needs the high-level C code to first be converted to machine code and then executed by the CPU.

    lalrpop is great. It's a completely different approach from nom, but for parsing a programming language, I would at least consider it. RustPython uses it.
  • What I like about rust
    2 projects | reddit.com/r/rust | 1 Nov 2022
    I still understand the priorities, there was lately some significant effort to improve performance ( and this gave this kind of hilarious extrapolation Python 3.14 Will be Faster than C++ - totally a clickbait, sorry ) - and they're still improving everything that makes static analysis reliable. So while I say I wish I have to respect the decisions that the core team are making, it paid off so far. There is also a very active community rewriting the interpreter in rust, this blows my mind. We have also to consider what happened to Perl. Perl 6 was a big retro-incompatible rewrite and ... it's basically dead now.
  • Rust going to impact python?
    2 projects | reddit.com/r/Python | 6 Oct 2022
    I mean, it already has happened. Now obviously that doesn't mean cpython is going to get replaced by a rust version any time soon, but I'd be cautious about saying never.

    Well, there's rustpython

    RustPython already exists for those who want it, it's totally possible there's a future world where it's more popular than CPython and people switch, but it's pretty unlikely https://github.com/RustPython/RustPython
  • How do the neovim plugins for OrgMode and Magit compare with the real thing?
    8 projects | reddit.com/r/emacs | 6 Aug 2022
    Honestly, my fantasy IDE would be something very much like emacs, but ported from the ground up in rust and streamlined a bit to avoid some of the bloat, and using RustPython for scripting the layers, including a badass kakoune/helix emulator.
  • Sooooo... are we going to have a plugin system or no? :)

    I’m still hoping out hope for something like RustPython https://rustpython.github.io. Using Python to extend SublimeText over the years has been amazing. I have tons of little helpers that were dirt simple to write. I would love to see Helix adopt a known and popular language that’s easy for anyone to use rather than something obscure like Rhai.
