NEO Emacs – GPU-Accelerated Emacs Powered by Rust

tommica

Oh that looks so pretty! I've wanted an excuse to try out emacs in the first place, and this could be it!

> Aiming for modern design, multi-threaded Elisp, 10x performance and 100% Emacs compatibility. I'm afraid that 100% compatibility may be very often at odds with multi-threaded elisp. So much in Emacs depends on global state :-/

Interesting interesting. I'm huge into Emacs and have felt like Emacs has needed a Neovim sort of moment for a while now. A lot of the modern features you'd expect out of an IDE are bad and slow in Emacs rn due to threading and pretty core issues to Emacs (so I cope and say I don't need autocomplete). But also suspicious of anything this AI generated which touts rust like this.

Seems fully vibe coded :(

Why not... Lem?

Watch demo button on the website doesn't work. I mean gnu-emacs is already quite snappy in Wayland mode.

It's hard to take this seriously when it has wonky Claude website design. Rewriting emacs in Rust also feels like a nonsensical task.

the webpage fills vibecoded in the worst way tbh; i don't think that's attractive to the current gen of emacs users maybe it targets net new users?

Does the "Watch Demo" button do anything?

With neovim's cult following I figured it was only a matter of time before somebody made a similar rewrite for Emacs, even if it does smell of vibe-coding based on the README. I don't see any notes in the README about alternative scripting engines, elisp was always the main thing that turned me off from emacs. Does anybody know if they plan to add something like Lua?

I've gone from being blown away by what LLMs could do with web design (I mean, it's impressive, especially what it does purely without vision...) to wishing it couldn't. Everything has become "same"y in a way that is hard to describe, kinda like AI generated images. Panda riding a unicorn? Impressive the first time. 1000 uncanny piss filter Pixar images later, you are begging for mediocrity to come back. Not that the README is any better. It's just a long string of Claudisms. Fuck. "Don't you ever get bored of pointing out that everything is AI slop?" Yes. I am very bored of pointing this out. I'll let you know when getting bored of it fixes the problem. I'm sorry if you think slop that will likely be unmaintained in a month and can be done even better by next month's model releases anyways is worth taking up a massive chunk of the HN frontpage forever, but I just don't agree.

Emacs written in rust.

The watch demo button doesn't work for me

Lost me with broken "Watch Demo" button

In my 20 years living inside Emacs, the running joke has always been that it's a great operating system lacking only a good text editor. With Neomacs bringing a GPU-accelerated display engine, and WebKit to the table... it looks like our operating system finally got a modern compositor. On top of that multithreading! (so some cache ops won't pause the editor!) Jokes aside, this is exactly the kind of mad-science evolution Emacs needs, rather than being hard-blocked by 1980s terminal-era C code. I'm curious how much of this project is done by AI? PS: kudos for doing it, I will definitely support it!

Interesting. I'm pretty jaded these days, so I decided to compile this and give it a go. I am actually a little surprised. So far, all of my configuration and packages have just worked out of the box. Eglot (LSP), Treesitter, evil, themes configuration and all my custom elisp and just kind of work. Brownie ponits there. Unfortunately, the developer has chosen to; for lack of a better phrase; gone batshit insane with cursor and window animations. The homepage looks nothing like what's OOTB either, so quite misleading to be honest. Otherwise, pretty decent job, feels smooth and will check in another year.

Do you have any evidence that neoemacs witnesses any speedup? It's a neat idea but I don't quite get why I'd want this without seeing some evidence I've also considered the possibility of a Rust rewrite of emacs, but after doing some more digging it seems like it may not be worth the effort. The remacs project seems to have been abandoned. I think they hit diminishing returns Moreover, this ready like AI slop
