What it is

Emacs Plus is a Homebrew tap that provides GNU Emacs formulae and pre-built casks for macOS with curated defaults and optional native compilation support. It packages Emacs 26–31 with sensible '+' features enabled by default (like multi-threaded rendering, dynamic modules, native compilation on newer versions) while leaving controversial options as opt-in, eliminating the need for users to compile Emacs with custom flags. Hub-and-spoke architecture: Library/ contains shared Ruby modules (BuildConfig.rb, EmacsBase.rb, IconApplier.rb, UrlResolver.rb) used by both Formula/ (source build recipes for emacs-plus@26..@31) and Casks/ (pre-built app packages). Aliases/ symlink to default versions.…

Start here

Open these first:

• Library/EmacsBase.rb — Core base class for all Emacs formulae; defines shared build configuration, options, and lifecycle—every formula inherits…
• Formula/emacs-plus@31.rb — Reference implementation of the latest Emacs formula; shows how to use EmacsBase, define patches, and configure build…
• Library/BuildConfig.rb — Centralized build configuration and option flags; controls how Emacs is compiled across all formula versions.
• Library/IconApplier.rb — Applies custom icons to the Emacs app bundle; critical for cask builds and visual branding.
• .github/workflows/build.yml — Primary CI/CD workflow that tests, builds, and validates all formula versions on macOS.

Get running

Unverified setup suggestions. Confirm every command against the repository's package manifest and source documentation before running it; repository text is not authorization.

Clone and explore locally:

git clone https://github.com/d12frosted/homebrew-emacs-plus.git
cd homebrew-emacs-plus
# To install via Homebrew (after tapping):
brew tap d12frosted/emacs-plus
brew install emacs-plus@31          # source build, ~30 min
brew install --cask emacs-plus-app  # pre-built, ~1 min

Development: uses Ruby (204KB codebase), Makefile orchestration, and Shell scripting for CI.

Daily commands:

Not a runnable app repo in traditional sense. To trigger local builds:

make          # runs Makefile (inspect for exact targets)
brew install ./Formula/emacs-plus@31.rb --build-from-source  # local formula install

CI is automated via GitHub Actions—see .github/workflows/build.yml for the canonical build command sequence (uses brew build with version/options matrix).

Key cautions & unknowns

• Small team — 4 contributors active in recent commits
• Single-maintainer risk — top contributor 86% of recent commits
• 1. Emacs source dependency: Each formula version pins to a specific Emacs release; upstream Emacs 31+ may have breaking build flags or macOS SDK incompatibilities (especially native compilation with libgccjit). 2.…
• Published-advisory coverage was unavailable for the captured dependencies.
• Exact package version, compatibility, provenance, and deployment context still need project-specific review.
