If you do a diff on the startup.el file from debian's emacs and the one from emacs bzr, you will quickly see the necessary changes. There are some other differences, but I've found these to be cosmetic. The startup.el file rarely changes and bzr will auto merge if possible when you do a bzr pull to update. As there can be byte code issues between versions of emacs, I also tend to install the emacs-snapshot and set the debian-emacs-flavor to 'emacs-snapshot. I also have 2 simple bash script that I run to setup appropriate symlinks and /etc/alternatives. Not necessary, but handy if you want to easily and consistently move between different versions of emacs such that running 'emacs' will give consistent version results. I install emacs into the default /usr/local tree. After running make install, I rm /usr/local/share/emacs/24.0.50/site-lisp and replace it with a sym link to /usr/share/emacs-snapshot/site-lisp I use load-path-shadow to verify everything is consistent and loading what I think it is after each new build of emacs. #!/bin/bash # Filename: setup-emacs.sh # Creation Date: Monday, 05 July 2010 10:33 AM EST # Last Modified: Tuesday, 06 July 2010 06:06 PM EST # Description: Simple script to setup emacs24 and make it the default alterntaive # if [ -f /usr/local/bin/b2m ]; then if [ -f /usr/local/bin/b2m.emacs24 ]; then rm /usr/local/bin/b2m.emacs24 fi mv /usr/local/bin/b2m /usr/local/bin/b2m.emacs24 fi if [ -f /usr/local/bin/ctags ]; then if [ -f /usr/local/bin/ctags.emacs24 ]; then rm /usr/local/bin/ctags.emacs24 fi mv /usr/local/bin/ctags /usr/local/bin/ctags.emacs24 fi if [ -f /usr/local/bin/ebrowse ]; then if [ -f /usr/local/bin/ebrowse.emacs24 ]; then rm /usr/local/bin/ebrowse.emacs24 fi mv /usr/local/bin/ebrowse /usr/local/bin/ebrowse.emacs24 fi if [ -f /usr/local/bin/emacs ]; then if [ -f /usr/local/bin/emacs24-x ]; then rm /usr/local/bin/emacs24-x fi mv /usr/local/bin/emacs /usr/local/bin/emacs24-x fi if [ -f /usr/local/bin/emacsclient ]; then if [ -f /usr/local/bin/emacsclient.emacs24 ]; then rm /usr/local/bin/emacsclient.emacs24 fi mv /usr/local/bin/emacsclient /usr/local/bin/emacsclient.emacs24 fi if [ -f /usr/local/bin/etags ]; then if [ -f /usr/local/bin/etags.emacs24 ]; then rm /usr/local/bin/etags.emacs24 fi mv /usr/local/bin/etags /usr/local/bin/etags.emacs24 fi if [ -f /usr/local/bin/grep-changelog ]; then if [ -f /usr/local/bin/grep-changelog.emacs24 ]; then rm /usr/local/bin/grep-changelog.emacs24 fi mv /usr/local/bin/grep-changelog /usr/local/bin/grep-changelog.emacs24 fi if [ -f /usr/local/bin/rcs-checkin ]; then if [ -f /usr/local/bin/rcs-checkin.emacs24 ]; then rm /usr/local/bin/rcs-checkin.emacs24 fi mv /usr/local/bin/rcs-checkin /usr/local/bin/rcs-checkin.emacs24 fi #!/bin/bash # Filename: emacs-alternative.sh # Creation Date: Monday, 05 July 2010 10:54 AM EST # Last Modified: Monday, 05 July 2010 11:38 AM EST # Description: Switch between alternative emacs versions # if [ $# -ne 1 ]; then echo "Error: Wrong # arguments" echo "Usage: $0 < 23 | 24 | emacs-snapshot >" exit 1 fi EMACS_VERSION=$1 echo "Configureing for emacs $EMACS_VERSION" cd /etc/alternatives if [ $EMACS_VERSION == "23" ]; then echo "Configureing for Ubuntu emacs 23" rm b2m ln -s /usr/bin/b2m.emacs23 b2m rm ctags ln -s /usr/bin/ctags.emacs23 ctags rm ebrowse ln -s /usr/bin/ebrowse.emacs23 ebrowse rm emacs ln -s /usr/bin/emacs23-x emacs rm emacsclient ln -s /usr/bin/emacsclient.emacs23 emacsclient rm etags ln -s /usr/bin/etags.emacs23 etags rm grep-changelog ln -s /usr/bin/grep-changelog.emacs23 grep-changelog rm rcs-checkin ln -s /usr/bin/rcs-checkin.emacs23 rcs-checkin elif [ $EMACS_VERSION == "emacs-snapshot" ]; then echo "Configureing for Ubuntu emacs-snapshot" rm b2m ln -s /usr/bin/b2m.emacs-snapshot b2m rm ctags ln -s /usr/bin/ctags.emacs-snapshot ctags rm ebrowse ln -s /usr/bin/ebrowse.emacs-snapshot ebrowse rm emacs ln -s /usr/bin/emacs-snapshot-x emacs rm emacsclient ln -s /usr/bin/emacsclient.emacs-snapshot emacsclient rm etags ln -s /usr/bin/etags.emacs-snapshot etags rm grep-changelog ln -s /usr/bin/grep-changelog.emacs-snapshot grep-changelog rm rcs-checkin ln -s /usr/bin/rcs-checkin.emacs-snapshot rcs-checkin elif [ $EMACS_VERSION == "24" ]; then echo "Configuring for local emacs 24" rm b2m ln -s /usr/local/bin/b2m.emacs24 b2m rm ctags ln -s /usr/local/bin/ctags.emacs24 ctags rm ebrowse ln -s /usr/local/bin/ebrowse.emacs24 ebrowse rm emacs ln -s /usr/local/bin/emacs24-x emacs rm emacsclient ln -s /usr/local/bin/emacsclient.emacs24 emacsclient rm etags ln -s /usr/local/bin/etags.emacs24 etags rm grep-changelog ln -s /usr/local/bin/grep-changelog.emacs24 grep-changelog rm rcs-checkin ln -s /usr/local/bin/rcs-checkin.emacs24 rcs-checkin else echo "Unknown emacs version $EMACS_VERSION" exit 1 fi -- tcross (at) rapttech dot com dot au ^ permalink raw reply [flat|nested] 4+ messages in thread

However, keep in mind that part of the build process also involves generating a 'dumped' version of emacs to help speed up startup. This means there can be some values, loaded in the dumped image, that cannot be easily overridden later. This is why I modify the startup.el file rather than just run additional init code to set various things. I use to just use additional init code at startup, but found I sometimes got inconsistent load-path outcomes and difficult to track down bugs. The nice thing about how I have things setup now is that updating from bzr to get the latest emacs sources is a simple as cd bzr/emacs/trunk sudo make distclean bzr pull ./configure make bootstrap sudo make install sudo lib-src/blessmail .... cd ~/bin sudo ./setup-emacs.sh and I'm done. If the emacs version number changes i.e. 24.0.50 to 24.0.51, I have to do the symlink thing with site-lisp, but that is very infrequent. >> >> There are some other differences, but I've found these to be cosmetic. >> The startup.el file rarely changes and bzr will auto merge if possible >> when you do a bzr pull to update. > > Thats cool. > >> >> As there can be byte code issues between versions of emacs, I also tend >> to install the emacs-snapshot and set the debian-emacs-flavor to >> 'emacs-snapshot.

I will give this a go > soon : certainly not what I would term simple ;) > Well, there is a much simpler method that works really well. However, it has a steep learning curve. Once you get the workflow sorted though, it is quite easy. I've used it for other packages, but have never got around to doing it for the emacs stuff. There was a web page somewhere that explained this in a concise step by step way, but I seem to have lost the link. The principal is pretty straight-forward. 1. Grap the deb-src package for emacs 23 2. Unpack it 3. replace the sources with the sources from emacs bzr 4. (Possibly) remove or update any patches. 5. Update the spec file 6. build a new deb package and install it. The biggest hassle with this method (apart from having to get more familiar with deb internals0 is step 4. However, if you just remove all patches except those that update startup.el to add the debian-emacs-flavor and debian-startup stuff, then its straight-forward enough. Most of the hard work has been done by previous maintainers. This approach has two main advantages. 1. You can easily install emacs on multiple machines 2. If you are ever unlucky enough to get an updated emacs bzr version with a nasty bug, you can quickly and reliably downgrade to the previous version MUCH easier and faster than you can using a direct bzr method. The only reason I've not gone this way is that I already had my current workflow in place before I learnt enough about deb packages to see how easy it is to build new packages when you can leverage off existing packages built for an earlier version. More recently, I've also started to seriously question using the debian/ubuntu emacs framework. While I really liked the ability to install/remove deb versions of emacs add-ons, there appears to be a drop off in interest in maintaining emacs for either ubuntu or debian (ubuntu is particularly bad). The packages are now getting to be very out of date (ubuntu is still shipping with emacs 23.1!) and I'm finding I'm running with more and more packages that are not from the deb repositories in order to get recent stable versions. As my emacs environment is pretty stable and I don't tend to install many new packages from the deb repositories, I'm seriously considering just uninstalling the whole lot and keeping my own branches of what I use and building manually.
