Use this script at your own risk. It currently works for me on my own machine, which as of writing is:
- OS X 10.8.5 (12F45)
- Xcode 5.0 (5A1413)
Your luck might vary. Do note that it does not build a universal application. The CPU architecture of the built application will be that of the machine it was built on.
Homebrew does not build a self-contained application though, which caused issues for me when I needed to rollback to a specific build. I found the easiest way to build a completely self-contained Emacs.app nightly from a specific date with custom patches was to do it manually.
So I decided to quickly hack together a script to automate that manual process. The code is a horrible hack, but it (seemingly) works as I'm writing this in Emacs built with it.
Myself I run the following command which will download a tarball of the
master branch, apply the sRGB patch, and build Emacs.app:
Or for example if you want to build the
emacs-24.3 tag, run:
Resulting applications are saved to the
builds directory in a bzip2
I decided to pull Emacs' source from a GitHub mirror rather than the official Bzr repo cause I'm not familiar with Bzr, and GitHub lets you easily download tarballs of any branch, commit or tag. And the tarballs from GitHub are just over 30MB, compared to ~1GB to pull the offical Bzr repo.
The only option passed in
--with-ns, meaning the resulting
application only supports the CPU architecture of the system is was built on.
There might be more side-effects to, but I haven't noticed any.
