Nathan Sobo recently open-sourced Zed, a code editor that focuses on performance, integrates AI capabilities, and supports software teams’ collaboration out of the box. For performance, Zed leverages a Rust code base, multicore- and GPU-optimized code, with a custom Rust GUI framework. For collaboration, Zed relies on CRDTs and team channels. Zed is currently Mac only.
My guess is that it has that default because they use Rust. Everyone uses rustfmt so everything looks the same and if you always format before a commit you never get massive diffs.
Most rust projects I’ve seen even have a ci job to check the formatting with rustfmt.
