This semester, with the (unfortunately blogless) Amy Wieliczka, I’ve been working sponsored by the Rennselaer Center for Open Source Software, on a project called Glide.
Glide
Excuse my broken GTK theme…

Glide is a Clutter/GTK based presentation application. I could go on for ages complaining about presentation applications, but um…maybe later, for now Glide is still a baby.

The code is on GNOME git, and, there is a fair amount there, and in fact, I think you could play with it today, using backgrounds+text/image elements, and some pretty Slide transitions, and probably make something a little more satisfying than you would in open office present. Build it, try it out. email me (racarr AT gnome), etc, etc…

Glide however is still in rapid development, within the next few weeks, there will likely be major changes. Probably an overhaul of the animations system, add a timeline editor for laying out transitions. An implementation of PDF export that doesn’t cheat. A templating/themeing system, along with an archive file format (containing all resources needed by the presentation! hoorah!). Then probably another pass over the UI…after this I’d like there to be some sort of 0.1 release.

Anyway, I’ve been putting off this post, and want to get it written…so…I’m going to leave it here. Thanks to Professor Moorthy and Sean O’ Sullivan for RCOS, a program which has perhaps been one of the defining experiences of my career as a student at RPI.

    please tell me it uses *.ODP as its native format.

  2. sebn Says:

    I just tried to build it, and configure complained about missing clutter-gtk-0.90.

    But I could not find such a version : http://www.clutter-project.org/sources/clutter-gtk/

    Ubuntu 10.04 comes with clutter-gtk-0.10, so I modified configure.ac and now it builds/installs/runs successfully.

    It’s good to see more work on Office app. Keep up good work :)

  4. DeeJay1 Says:

    A few notes WRT to the repository, especially the po dir:
    please remove .intltool-merge-cache, Makefile, POTFILES and stamp-it files from it, they are unnecessary as they should be autogenerated…

  5. Alex Says:

    This is really exciting and I hope that something useful and mature will grow out of it. After the now dead criawips, it would be great to have something to complement Abiword and Gnumeric in Gnome Office.


  6. awesome! Can’t wait for this to hit Ubuntu :-)

  7. Hylke Says:

    This is great!
    OpenOffice.org sucks so bad. I’ve been looking for a simple presentation tool for ever. Let me know if you need an icon. :)

  8. Tom Says:

    Very cool. Will it be like Keynote?
    But why did you use C instead of Python or Vala? I really fear that this will be abandoned at some point, because C is not really for app development and finding people maintaining a C codebase will be hard in a few years.

  9. ReinoutS Says:

    Very interesting project indeed!
    Have you considered coming to GUADEC 2010 in The Hague and presenting your project there in a lightning talk? (Full paper submissions are closed already, sorry!)

  10. Robin Says:

    “with an archive file format”

    Do you plan to use the OpenDocument ODP format?

  11. Stephane Says:

    You should remove po/Makefile and po/Makefile.in from git and update the configure.ac file with the dependency on Clutter 1.2 (not 1.0)

  12. stormy Says:

    Awesome!

    I look forward to seeing a demo and trying it out.

    One of the things that I think presentation tools really, really need is a way to look at a whole bunch of slides and pick and choose (drag and drop) some of them into a new presentation. While keeping the whole set available.

  13. nacho Says:

    It is great to see this project. Thanks a lot for it. BTW I’ve started having a quick look at the code and as minor thing, there are some files with gpl 3 and others as 2.

  14. Np237 Says:

    Great idea! This is the thing that GNOME lacks most currently.

    I hope to be hearing from it soon.

  15. vincent torri Says:

    if you want some ideas of layout and animations:

    http://watchwolf.fr/public/Eyelight/eyelight.mpeg4

    it’s a quite sexy presentation tool written with the Enlightenment Foundation Libraries (http://www.enlightenment.org/), completely themable.


  16. Any plans for a video or flash export that isn’t rubbish :) openoffice goes to flash but loses animations.

  17. Bob Says:

    Do exists a clutter-gtk-0.90 package? Perhaps it is clutter-gtk-0.9?
    Or even better: what about switch to clutter-gtk-0.10?


  18. Some time ago I did a program which allowed to export a presentation (plus the audio recorded during the conference) to Flash, to allow people to put them in their webs using less bandwidth and having better quality than a video, but it’s quite old, so…

    What do you think about allowing to export to SVG+HTML, plus a little of JavaScript to do the transitions and the AUDIO tag from HTML5 for the audio? Or directly using the CANVAS tag.

  19. Luis Says:

    Looks cool- I plan to try it out for my GUADEC talk.

    Along the lines of what Robin said, it’d be great if the data format were standard- either something like odp, or better something like HTML5 that didn’t require export.

  20. jeff Says:

    Holy shit. You are a hero. You have no idea how badly we need a nice, simple and efficient gnome-centric tool like this for making presentations! Actually you probably do ;)

    Just want to make an early feature request. The only killer feature I *need* (which makes me use OOo Impress) is the “presenter console”: http://wiki.services.openoffice.org/wiki/Presenter_Screen

    It’s the key to making impressive, zen-style presentations, and avoiding “death by powerpoint”.

    Cheers!

  21. think!! Says:

    Oh, I love the effort to create a new Presentation Software, I think the office software should be more divided and therefore this is a wonderful project.
    Perhaps it could be something to linux, as Keynote is to Mac OSX.


  22. Exciting. I was just thinking about a Clutter powered presentation tool a few days ago. I was wondering why you did not use Seed for this? It seems like a good fit for a C-core with Seed on top?


  23. I get a segfault when I run it from the src/ dir. Admittedly I bumped clutter-gtk to 0.10 since that’s what I have here – which might be at fault. Here’s the bt:

  24. kappa Says:

    Cool! I am eagerly looking forward to trying Glide.

    Will you please provide instructions on compiling it?

    A list of dependencies will also help.

  25. Tom Says:

    So the GSoc for “Ease” will reimplement this in Vala? Do you talk to each other? Why not have a GSoc for Glide?
