railwaycat/homebrew-emacsmacport

This system is a Homebrew tap that builds and distributes custom macOS versions of Emacs, specifically the emacs-mac port. It provides stable and experimental formulas for versions 28 through 32, along with corresponding Homebrew casks for both Intel and Apple Silicon architectures. The repository automates the build process using dedicated scripts and CI pipelines to apply macOS-specific patches, manage dependencies, and generate distributable application bundles.

The tap now provides a stable formula for Emacs 28 (emacs-mac@28) alongside new experimental formulas for upcoming versions: emacs-mac@30exp, emacs-mac@31exp, and emacs-mac@32exp. The Emacs 28 formula includes support for native compilation, xwidgets, and various icon options. The experimental formulas track specific commits or branches from the jdtsmith fork, with Emacs 31 and 32 being HEAD-only builds. All formulas support options for native compilation, xwidgets, unlimited select, and Metal-based double buffering.

New Homebrew casks have been added for Emacs-mac versions 28 (v28.3-rc1) and 29 (v29.4), providing installers for both Intel and Apple Silicon Macs. These casks introduce granular macOS version requirements, distinguishing between macOS 13 (Ventura), 14 (Sonoma), and 15 (Sequoia) for Apple Silicon builds, and ensuring Intel builds target macOS 13. The v29 casks replace the previous default version, while the v28 casks offer an alternative stable release, with the spacemacs-icon variants providing a specific application icon.

Casks · high confidence

A new symbolic link named 'emacs-mac' has been added to the Aliases directory, pointing to the [e-mail redacted] formula file. This allows users to reference the specific version 29 of the emacs-mac formula using a simpler alias name.

The icons directory now includes a Makefile to generate PNG previews from ICNS source files and a README documenting the available icon choices. Users can now select from additional icon variants, including several from the emacs-icons-project (such as EmacsTerm, EmacsVapor, EmacsIcon1-9, and various card styles), as well as new options like the retro-sink black-and-white icon, gnu-head, modern, sjrmanning, spacemacs, and sexy icons.

The repository now includes a structured set of build scripts in the \build-scripts/\ directory to automate the creation of macOS Emacs bundles. This change introduces version-specific source fetchers (\fetch-src-emacs-28.sh\, \fetch-src-emacs-29.sh\, \fetch-src-emacs-30exp.sh\) that retrieve code from specific upstream commits and apply necessary patches, such as multi-tty support and natural title bar adjustments. It adds \Brewfile-29\ and \Brewfile-30\ to define Homebrew dependencies (including \tree-sitter\ and \libyaml\) and a core \build-emacs.sh\ script that configures the build with modules, xwidgets, and tree-sitter support. Supporting utilities like \copylib.rb\ handle library embedding and \install\_name\_tool\ adjustments for self-contained apps, while \make-zipball.sh\ generates the final distributable archives with SHA256 checksums.

The repository has been reorganized to support modern build and distribution workflows. New CI configurations for Azure Pipelines and Travis CI have been added to automate building and packaging Emacs Mac Port for various macOS versions (10.14, 10.15, 11). The old Homebrew formula file (emacs-mac.rb) has been removed, and the README has been significantly updated to reflect support for Emacs 29 and experimental versions (30, 31, 32), including instructions for Homebrew formulas and casks, as well as pre-built downloads for Intel and Apple Silicon Macs. A BSD 2-Clause License file has also been added.

(repo-wide) · high confidence

A new Library directory has been introduced to house shared code used across formula versions. This includes Icons.rb, which centralizes the names and SHA-256 hashes of all supported application icons, and UrlResolver.rb, which provides logic to resolve paths for patches and icons based on whether the build is running locally or within the Homebrew tap environment.

This update adds and refines several patches for the macOS Emacs build. It enables multi-tty support by allowing terminal frames on macOS (previously restricted to Windows), fixes ARM64 code-signing issues by correcting the configuration pattern and re-signing after dumping, and improves font metrics by preferring OS/2 table values for ascender/descender/linegap. It also introduces user-controllable title bar styles (transparent, dark, light, and hiding document icons) via defaults, adds a new \mac-use-title-bar\ customization option, fixes the \man\ command's portability by using POSIX character classes, and ensures compatibility with macOS 26 by disabling specific event features and using the non-prefixed \posix\_spawn\_file\_actions\_addchdir\_np\ when needed.
