emacs23?

It will be available in the incoming new version (trisquel 3.5).

In the meantime, you can install it manually, read this piece of irc log about it:

2010-02-16 02:42:56 pieterc Any idea how I install emacs 23 on my FSF membership trisquel -card?
2010-02-16 02:54:08 quidam pieterc: you can install it as emacs-snapshot, I think
2010-02-16 02:54:48 quidam pieterc: also, you can use this ppa: deb http://ppa.launchpad.net/ubuntu-elisp/ubuntu jaunty main
2010-02-16 02:56:13 quidam I'm not sure if the card has full system persistence or just for the home partition
2010-02-16 02:56:29 quidam you can tune that up anyway
2010-02-16 02:56:37 pieterc tested that - only home dir
2010-02-16 02:56:46 pieterc *sigh* ;)
2010-02-16 02:57:41 quidam pieterc: it is the default as it is safer, but you can change it by changing the label of the home partition
2010-02-16 02:58:03 quidam now it is home-rw, right?
2010-02-16 02:58:08 pieterc yes indeed
2010-02-16 02:58:29 quidam then you can relabel it to casper-rw, that will do the trick
2010-02-16 02:58:47 pieterc then my entire root will be copied on that partition?
2010-02-16 02:59:02 quidam no, just the files you add or modify
2010-02-16 02:59:08 pieterc ok, cool
2010-02-16 03:01:08 quidam pieterc: emacs23 is in the incoming version repos
2010-02-16 03:01:39 quidam pieterc: as soon as it is finished, we will also release an update for the card
2010-02-16 03:01:43 pieterc sudo apt-get dist-upgrade when relabeled should be ok?
2010-02-16 03:01:47 pieterc ah ok
2010-02-16 03:01:51 pieterc great!
2010-02-16 03:02:32 pieterc I'll need a reboot I'm afraid - accidentally removed the card and now it doesn't recognise it as my root system anymore
2010-02-16 03:02:35 quidam pieterc: I recommend you to do as less changes as possible to the card using persistence
2010-02-16 03:02:51 quidam so, no dist-upgrade
2010-02-16 03:03:19 quidam otherwise the kernel will be updated and it might break things
2010-02-16 03:03:20 pieterc because the casper-rw partition is too small?
2010-02-16 03:03:25 pieterc ah ok
2010-02-16 03:03:26 pieterc alright
2010-02-16 03:03:37 quidam no, because it is a glorified live-cd, with some limitations
2010-02-16 03:03:48 pieterc ok
2010-02-16 03:03:59 quidam that is why the default setting is home-rw
2010-02-16 03:04:05 pieterc I'll reboot now and relabel the partition
2010-02-16 03:04:10 quidam it is safer that way
2010-02-16 03:04:15 pieterc right :)
2010-02-16 03:04:22 pieterc I don't like safe ;-)
2010-02-16 03:04:35 quidam ok, do not relabel it while in a live session
2010-02-16 03:04:35 pieterc I meant, I like to take a risk
2010-02-16 03:04:53 pieterc yes, I was planning on rebooting into my normal system ;)
2010-02-16 03:04:54 quidam oh, the card is very easy to rebuild if you mess it up
2010-02-16 03:05:11 pieterc with the DVD and use the create bootkey thing?
2010-02-16 03:05:31 pieterc USB startup disk creator;)
2010-02-16 03:05:44 quidam the dvd is the source code
2010-02-16 03:05:59 pieterc ok
2010-02-16 03:06:01 quidam to rebuild the card you can use this image: http://devel.trisquel.info/trisquel_3.0-FSF-3_i686.iso
2010-02-16 03:06:12 quidam and this script: http://devel.trisquel.info/live-usb-fsf.sh
2010-02-16 03:07:23 pieterc thanks
2010-02-16 03:07:24 pieterc got that
2010-02-16 03:07:30 pieterc thanks for your explanations
2010-02-16 03:07:37 pieterc will reboot now into normal system
2010-02-16 03:07:46 quidam ok, see you
2010-02-16 03:07:51 pieterc bye

If someone has the time please make a wiki entry with this. As the package is already in the upcoming repos I'm colosing this.
