This repository allows you to build Emacs for Mac OSX. If you are not familiar with Emacs building process I suggest you to grab a ready-to-use binary version at Emacs For Mac OSX.

Ok this is an other Emacs build but what are the differences with Emacs For Mac OSX?

• You can choose the version you want to build from any commit within the whole Emacs history. Well this is true for most of them (Emacs >= 24).

• A stand alone Emacs.App is generated. This means you only need dependencies for the building process. Then you can deploy the Emacs.App on any OSX desktop. For the curious all non-system libraries are stored into the Contents/Resources/lib directory.

• Some very basic patches are applied:

  • Full screen support: Emacs supports OSX full screen mechanisms but lacks of a full screen toggle function. This patch adds ns-toggle-fullscreen which allows you to toggle full screen from Emacs itself.

  • Show git commit ID in emacs-version:

  GNU Emacs 25.0.50.1 (x86_64-apple-darwin, NS appkit-1404.13 Version 10.11.1 (Build 15B42), git sha1 d5ee655) of 2015-10-28
  

All patches are included in emacs-patches-directory (which is located in the application bundle at Contents/Resources/patches). A list of all applied patched is stored in the emacs-patches-list variable.

The view-emacs-patches function opens a dired buffer in emacs-patches-list. The view-emacs-patch opens a particular patch.

• Users Emacs directory: instead of just searching init.el in ~/.emacs.d your configuration files will be searched in that order:

  • ~/.emacs.d-GIT_COMMIT (i.e. ~/.emacs.d-10292e9)
  • ~/.emacs.d-EMACS_VERSION (i.e. ~/.emacs.d-24.4.50.1)
  • ~/.emacs.d-EMACS_MAJOR_VERSION (i.e. ~/.emacs.d-24)
  • ~/.emacs.d-EMACS_MAJOR_MINOR_VERSION (i.e. ~/.emacs.d-24.4)
  • ~/.emacs.d

  This is useful if you need to test your configuration against several versions at the same time.

• The C source files are included in Contents/Resources/src in the application bundle.

• A small emacs wrapper is deployed into Contents/MacOS/bin/emacs to call emacs from the CLI. You can link this file to your search path.

First you need to install following tools (you may want to use brew for that):

• automake
• jpeg
• giflib
• libtiff
• imagemagick: you need to activate some options:
  • --with-hdri
  • --with-fontconfig
  • --with-ghostscript
  • --with-jp2
  • --with-liblqr
  • --with-rsvg
  • --with-libtiff
  • --with-libwmf
  • --with-little-cms
  • --with-little-cms2
  • --with-openexr
  • --with-perl
  • --with-quantum-depth-16
  • --with-webp
• gnutls
• librsvg
• texinfo
• pkg-config
• jansson

You also need to checkout an Emacs git repository. I suggest you to use Savannah's which is the most up-to-date.

git clone git:https://git.savannah.gnu.org/emacs.git

Once all requirements are installed you can just run:

./build-emacs

If you want to build a specific version you just can pass the commit id or tag to the build-emacs script:

./build-emacs emacs-24.4

Some options are only available on specific OS.

• relocating allocator for buffers: Not supported on darwin (does not work with system malloc).
