Emacs switched the version control system from Bazaar to git yesterday, so now is the time to start hacking away at Emacs.

Emacs: The Best Thing Since Sliced Bread If It Wasn’t For The Fact That Emacs Was Actually Invented Before Sliced Bread.

This is a very short how-to guide on building and then contributing to Emacs.

Depending on what OS you’re running, you should install some libraries and stuff.  On Debian/Ubuntu you’d say something like

sudo apt-get build-dep emacs24

 

(See the end of this post for instructions for other operating systems.)

Then you need to get the Emacs sources and build Emacs.  Here’s how on most Linux systems:

git clone git://git.savannah.gnu.org/emacs.git
cd emacs
make
./src/emacs &

 

And you’re off! If you know what you want to add to Emacs, just start hacking away. If not, you should have a look at the wishlist in the Emacs bug tracker.  Starting with a new feature can be less daunting than starting with a bug, since it’s more open ended.  And more fun.

First we need to get the bug tracker into Emacs.

M-x package-install RET debbugs RET

Ready for action!

M-x debbugs-gnu RET C-a C-k wishlist RET

 

This will list everything that anybody wanted, but nobody got around to doing anything about.  Find one you think look interesting, hit enter to read more about it, and if you think you want to have a go, start hacking away.

When you’re done, make a diff, reply to the bug report with F, and include the diff in the email.

Emacs requires a copyright assignment on all bits that are larger than 15 lines.  Send an email to [email protected] saying you wish to assign your Emacs code to the FSF, and they’ll get back to you on the paperwork, which is very un-daunting.

If you’re fixing lots of bugs and adding lots of new code, just ask for commit rights to the Emacs repository, and your code will fly out a lot faster.

Go forth and Emacs!

Appendix:

If apt-get build-dep doesn’t work for you on Debian/Ubuntu, you could say something like

sudo apt-get install gcc automake autotools libmagick++-dev \
  libgtk2.0-dev libxft-dev libgnutls-dev libdbus-1-dev libgif-dev

 

On Fedora you’d say

sudo yum install gcc makeinfo texinfo gtk3-devel gnutls-devel\
 giflib-devel ImageMagick-c++-devel autotools automake \
 libXaw-devel libpng-devel ncurses-devel libxml2-devel
