Xmonad

Darcs

Git-annex

Although, it would be very hard to write SIMD performant code in Haskell, even its string libraries don't use any optimization tricks.

I was excited when I heard of it, but I thought Darcs had run into some major issues with patch theory and exponential merges. Other than it being written in Haskell, why would I use it over git?

Well, speed issues are currently not that noticeable (a lot of times passed since initial bumps) but I'm pretty sure some large repositories (more than millions of lines of patches) wouldn't be able to work with it.

git is a whole different story compared to darcs, darcs is simpler to use, especially when merging.

if it was consistently fast I'm pretty sure git wouldn't be as popular as it is.

there is rust vcs https://pijul.org/ that seems to be doing the same thing as darcs but faster.

so I guess CJefferson's controversial comment stands :D

It will only be a matter of time before someone rewrites xmonad in Rust.

Negative time, actually: https://github.com/kintaro/wtftw

(there's an i3 inspired one as well, I forget the link)

Nice!

I think this is the other one you were thinking of: https://github.com/tsurai/xr3wm

There is a different one based on wlc (So it's a wayland compositor, rather than just an X11 window manager). The one you linked doesn't seem to have been updated since 2015

Edit: Here it is: https://github.com/Immington-Industries/way-cooler

I need an R5RS+ Scheme that is tightly integrated with Rust. High-level and fast enough, with the ability to drop down into Rust for speed.
