Remacs is a community-driven port of Emacs to Rust. Emacs is an extensible, customizable, self-documenting real-time display editor.
Although most Emacs code is written in a dialect of Lisp, the interpreter for that Lisp (along with low-level stuff like IO) is written in C. The goal of Remacs is to rewrite the C code in Rust while maintaining “bug-for-bug compatibility” with Emacs. The rewrite is incremental.
Remacs should generally behave identically to Emacs. Remacs aims to be fully Elisp compatible. Remacs also aims to use existing Rust crates wherever possible, and create new, separate crates where the code could assist others.
Remacs doesn’t add any additional functionality to Emacs.
The developers believe that porting Emacs to Rust provides many opportunities such as leveraging the crate ecosystem, drop support for legacy compilers and platforms, and add docstrings / unit tests to core functions that aren’t exposed to elisp.
