Colloquium: Narrative-based presentation system

Colloquium is a new approach to presentation tools which centres on narrative, not slides.

In Colloquium, rather than acting as the framework for your words, slides are embedded into the "narrative" of your presentation and only come into play when there's a need for a visual aid. Concentrating on the narrative makes it much easier to give a clear presentation which flows naturally.

You can use the narrative in whatever way you like, which could range from short bullet-pointed notes all the way up to writing your talk word-for-word.

Narrative


Within the narrative, you can double-click a slide to open it in a familiar kind of editor. Drag and drop images, shift-drag to create text boxes, and so on. A stylesheet system helps to enforce design consistency.

Editor


Colloquium's presentation clock shows the passage of time and your progress through the talk on a bar chart. When you're running fast, the difference is coloured green. If you're running slow, it's red. You can see at a glance how you're doing, even though all slides do not take an equal amount of time.

Timer


Colloquium stores your presentations in a transparent, plain text format. Files behave well with all version control systems for easy tracking and merging of changes. You can easily edit files by hand if you need to, or even generate them programmatically.

Here's how it looks, in case you were wondering:

: This is an example file.  This line is normal narrative text
SLIDE {
    SLIDETITLE: Here is the title of the slide
    IMAGE[1fx1f+0+0]: /home/user/image.png
}
: Here is some more narrative text

Installation instructions

Colloquium uses the Meson build system (http://mesonbuild.com), which works with Ninja (https://ninja-build.org/). Start by installing these if you don't already have them. For example, in Fedora:

$ sudo dnf install meson ninja-build

or for Debian/Ubuntu:

$ sudo apt install meson ninja-build

or for Mac OS users, using Homebrew (https://brew.sh):

$ brew install meson ninja

You will also need the gettext and GTK 3 development files:

$ sudo dnf install gettext-devel gtk3-devel

or:

$ sudo apt install gettext-devel libgtk-3-dev

or:

$ brew install gettext gtk+3

This should pull in the other dependencies, which are GDK, GLib, GIO, Cairo, Pango and gdk-pixbuf. You may need to additionally install Flex and Bison.

Set up the build directory using Meson:

$ meson build

Compile Colloquium using Ninja:

$ ninja -C build

To install:

$ sudo ninja -C build install

Running the program

Colloquium should appear in your desktop environment's menus. Alternatively, it can be started from the command line:

$ colloquium

The first time Colloquium runs, it will show an introduction document to help you get started.
