Text-based presentations

There have been a few posts on planet KDE about text-based presentation tools (1 , 2 , 3) and while their solutions are all probably better than mine, I have to say I did something in the area about a year ago.

Since I like restructured text and PyQt that's what it's based on, but you can just use it with vi and a wyse60, if you want.

My project is called Tobogan and it has a working version.

It has a GUI, but let's ignore it for this post about text-based software ;-) and show the text behind it:

Why use Tobogan

(If you are a nerd)

:transitions: from_left,to_left,from_top,to_top,from_right,to_right,to_bottom,fade_out

It's nerd-oriented

It's trivial to display source code, with
proper syntax highlighting.

.. code-block:: python

    from base64 import *
    def myFirstFunction():
          print b64decode ('YnllIHdvcmxkIQ==')

Even for things like shell sessions.
Dammit, I am a nerd, I will try to add every nerd
feature I deem cool.

It does things simply

This is a subtitle?

Wanna show a flickr photo?

.. code-block:: rst

    .. flickr:: myPhotoTitle

How about using to share your files?
And whatever else you can think of, it probably
**can**\  be done.

.. footer:: Smart thing goes here

And here is the result after running on it.


  • If you move the cursor to the top, you will get (broken?) previous/next arrows
  • If you click on the window, you get to the next slide.

I have not touched this in almost a year, and it would need lots of love, but it's not a bad concept, IMVHO.

What I am plotting...


Ok, here's what I have been doing:

  • Daddy work. Lots of it. Fun!
  • Actual work. Lots of it. Fun, but not so much!
  • Worked a little more in RA-Flip. Play/Stop/Pause is done. The editing mode and opening/saving files is pretty much done, so it will be fully functional as soon as I can spend an afternoon in it.
  • Tobogan (My slideshow software). It works nicely. There are many rough spots and it needs a few features:
    • Some way to edit the CSS for individual slides in a nice manner. Like setting backgrounds and colours (and not much else)
    • A nice way to save the slideshow so it ends all in a single folder.
    • Many UI details
    • Docs
    • A site
  • BartleBlog: it has worked well for me for a long while, since I have been posting this blog using it. And really, it's a nice blog, isn't it? ;-) But of course, there is stuff to be done:
    • Many UI details
    • Decent flickr and openomy uploaders/managers
    • Some extra gadgets I have in mind
    • Docs
    • A site

And that's all I have in mind right now. Except maybe a graphical Befunge interpreter, but that's not really important ;-)

New project: Tobogan

As a result of my playing with mootools and creating powerpoint-style slideshows on webpages from restructured text, I am pretty much decided about turning this into a standalone, real application.

I am doing a PyQt4 frontend, and restructured text addons to generate the slides.

The native file format is restructured text itself, and it supports basic transitions between slides.

It still needs a ton of work, but here is a video showing how it looks after a couple of days hacking. You can see the current UI, a document's source, and a demonstration using firefox (only because Konqy doesn't suppose opacity, the rest of the transitions work even better on Konqueror)

It's Ogg/Theora and 3MB (thanks!): the video
