Emacs Plus formulae for the Homebrew package manager

Emacs Plus

About

Emacs Plus is → GNU Emacs formulae for macOS → Homebrew package manager. It offers a wide rage of extra functionality over regular → Emacs package. Emacs Plus intent is to give the most of ‘plus’ stuff by default, leaving only controversial options as opt-in. Please refer to → Options section for more information.

$ brew tap d12frosted/emacs-plus
$ brew install emacs-plus    [options] # install the latest release (Emacs 27)
$ brew install emacs-plus@26 [options] # install Emacs 26
$ brew install emacs-plus@27 [options] # install Emacs 27
$ brew install emacs-plus@28 [options] # install Emacs 28

Feel free to open an issue or contact me via email if you face any issues, questions or feature requests. I love pull requests, so do send them. You might want to check → Development guidelines to have better understanding on how to contribute.

Install

Emacs Plus contains separate formulas for different Emacs versions:

• emacs-plus install current release version (Emacs 27);
• emacs-plus@26 install Emacs 26, previous release version;
• emacs-plus@27 install Emacs 27, current release version;
• emacs-plus@28 install Emacs 28, development version.

  $ brew tap d12frosted/emacs-plus
  $ brew install emacs-plus    [options] # install the latest release (Emacs 27)
  $ brew install emacs-plus@26 [options] # install Emacs 26
  $ brew install emacs-plus@27 [options] # install Emacs 27
  $ brew install emacs-plus@28 [options] # install Emacs 28
      

By default (without any addition options) this formula install Cocoa version of Emacs with support of gnutls, imagemagick, librsvg, libxml2, dynamic modules and multicolor fonts. Please see the list of available options to disable any bit of default behaviour or add even more stuff.

Reinstall

If you wish to reinstall emacs-plus with you should not use reinstall command of brew (not related to this formula, it’s a general advice). Instead, you should uninstall a package and then install it with desired options.

Avoid reinstall even if you want to reinstall with the same set of options, otherwise you will likely to get compilation errors! For example, #218 and #321.

In short, brew doesn’t really support options. They break time to time (brew#4793, brew#7397, brew#7498 to show a few).

$ brew uninstall emacs-plus
$ brew install emacs-plus [options]

Emacs 26 options

Emacs 26 comes without any available options due to → #195.

Emacs 27 and Emacs 28 options

Option	Description
--with-ctags	don’t remove the ctags executable that Emacs provides
--with-dbus	build with dbus support
--with-debug	build with debug symbols and debugger friendly optimizations
--with-mailutils	build with mailutils support
--with-no-frame-refocus	disables frame re-focus (ie. closing one frame does not refocus another one)
--with-no-titlebar	build → without titlebar
--with-x11	build with x11 support
--with-xwidgets	build → with xwidgets support
--without-cocoa	build a non-Cocoa version of Emacs (terminal only)
--without-imagemagick	build without imagemagick support
--HEAD	build from emacs-27 branch (only for emacs-plus@27)
--with-native-comp	build with native compilation aka → gccemacs (only for emacs-plus@28)

By default emacs-plus builds the Cocoa version of Emacs.

emacs-plus unconditionally enables support for gnutls, librsvg, libxml2, little-cms2 and dynamic modules.

No Titlebar

This patch is enabled with the --with-no-titlebar option. It is meant for use with window tiling applications like → yabai, → chunkwm or → amethyst so that the titlebar you will never need to click on won’t take up screen real estate. If you see gaps between your emacs frames and other windows, try this:

(setq frame-resize-pixelwise t)

Xwidgets (webkit)

Browse the web in Emacs as in modern browser.

The original → Emacs xwidgets builds and works on macOS however must be used with X11 and hence not practical option on macOS. This version enables xwidgets on native macOS Cocoa via embedding a native webkit window.

More details can be seen here → Veshboo’s emacs branch.

System appearance change

This patch is enabled by default and can’t be disabled. It adds a hook, ns-system-appearance-change-functions, that is called once the system appearance is changed. Functions added to this hook will be called with one argument, a symbol that is either light or dark. This mainly allows loading a different theme to better match the system appearance.

(defun my/apply-theme (appearance)
  "Load theme, taking current system APPEARANCE into consideration."
  (mapc #'disable-theme custom-enabled-themes)
  (pcase appearance
    ('light (load-theme 'tango t))
    ('dark (load-theme 'tango-dark t))))

(add-hook 'ns-system-appearance-change-functions #'my/apply-theme)

Note that this hook is also run once when Emacs is initialized, so simply adding the above to your init.el will allow matching the system appearance upon startup. You can also determine what the current system appearance is by inspecting the value of the ns-system-appearance variable.

The hook is NOT run in TTY Emacs sessions.

gccemacs

gccemacs is a modified Emacs capable of compiling and running Emacs Lisp as native code in form of re-loadable elf files. As the name suggests this is achieved blending together Emacs and the gcc infrastructure.

→ Andrea Corallo

While gccemacs gives performance boost in many scenarios, this feature is still experimental and might require time and effort from your side for it to work! Use at our own risk :)

Please see official → gccemacs documentation for more information.

Knows issues:

• ld: library not found for -lSystem. This only happens on older versions of gcc installed by Homebrew. Please execute $ brew reinstall gcc libgccjit to resolve this issue.
• Errors during compilation of your init.el. Try running Emacs with -Q option and give it some time to compile everything (maybe run M-x to force compilation) - you shall see buffer *Async-native-compile-log* in the list of buffers.

Emacs configuration

Emacs is a journey. And for some of you these projects might be inspiring.

Known Issues

Please checkout → Issues page for a list of all known issues. But here are several you should be aware of.

emacs dependency in other formulas

In some cases (like when installing cask) regular emacs package will be required. In such cases you might want to install all dependencies manually (except for emacs) and then install desired package with --ignore-dependencies option.

$ brew install cask --ignore-dependencies
