## Health v2 (maintenance only)
Score: 32/100 (v2, computed 2026-09-03T02:20:16.233290+00:00)
- activity 0, release rhythm 35, longevity 100
- inputs: {"age_days": 3571, "days_push": 1974, "days_rel": null, "gap_med": null, "n_releases_24m": 0}
- flags: no_releases
- formula: round(0.45*activity + 0.35*rhythm + 0.20*longevity); archived -> min(score, 10)

## What it is
Remacs is a community-driven port of GNU Emacs to Rust, replacing parts of the C codebase with Rust implementations while remaining compatible with Emacs Lisp. The project is no longer maintained, with users directed to emacs-ng as an alternative Rust-based Emacs fork.

## Use cases
- run an Emacs editor built with Rust instead of C
- contribute to porting Emacs C primitives to Rust
- use Emacs Lisp with a memory-safe implementation
- build a custom Emacs fork with Rust integration
- research how Rust and C interoperate in a large codebase

## When to choose
- you want a Rust-based Emacs implementation for experimentation or research
- you need a real-world example of incrementally porting C to Rust
- you want to study Emacs internals rewritten in Rust

## When to avoid
- you need a maintained, production-ready editor - the project is abandoned
- you want new features or bug fixes - use GNU Emacs or emacs-ng instead
- you rely on timely security updates

## Facets
- artifact type: application
- maturity: abandoned
- function: editor, interpreter, programming-language
- domain: text-editors, developer-tools, programming-languages
- platform: windows, cross-platform
- tags: emacs, rust, fork, elisp, unmaintained, linux, macos
