Kary - Presentation based on Kivy language

Kary is a tool to create presentation using Kivy language.

Installation

You need to have Kivy 1.0.7 minimum to make it run (http://kivy.org/)

Usage

::

kary <directory_of_your_presentation>

OR

kary <filename.kv>

How does it work ?

Kary is defining few classes needed for creating slides:

• Slides: a widget that will contain a list of Slide. It must be your root widget, and cannot be used inside another widgets.
• Slide: base widget for constructing more complex Slide, like with or without title, with image content, or video content etc.
• SlidesBackground: this widget will be always created by Slides. Add a rule if you want to customize the background of slides.
• SlidesForeground: this widget will be always created by Slides. Add a rule if you want to customize the foreground of slides.

Create a directory with this layout::

mypresentation/ presentation.kv templates.kv (optional) ... (put any files you want to use in the kv)

In templates.kv, you could define some Kivy template to be used in your presentation.kv::

#: kivy 1.0

# For all your slides, you want to have the same Label for representing
# a title, with always the same background and settings.
[Title@Label]:
    text: ctx.text
    text_size: self.width - 60, None
    halign: 'left'
    size_hint_y: None
    height: 100
    font_size: 36
    color: labelcolor
    canvas.before:
        Color:
            rgba: 0, 0, 0, .2
        Rectangle:
            pos: self.pos
            size: self.size

# This is a simple slide with title on top and content on bottom.
[SlideContent@Slide]:
    GridLayout:
        pos: root.pos
        cols: 1
        Title:
            text: ctx.title
        BoxLayout:
            padding: 50
            Label:
                color: labelcolor
                text: ''.join(ctx.content)
                font_size: ctx.get('font_size', 36)
                text_size: self.width, None

Then, in the presentation.kv, you can use it like that::

#!/usr/bin/env kary
#:kivy 1.0

Slides:

    SlideContent:
        title: 'Hello world'
        content:
            ('This is the first line\n',
            'This is the second line')

    SlideContent:
        title: 'My last slide'
        content: ('Any questions ?, )

Then, open a terminal, and type::

kary mypresentation

And your presentation will be opened !
