Present slideshows from plaintext files. Illuscribe is a simple program written in C using the Xlib and stb_image libraries. It parses plaintext files and renders them as presentations.

For an example of what a slideshow may look like, view the example/ folder

Here are the basic commands/functions:

• slide: name - Declares a slide. Slides contain boxes.
  • name: string
• box: name, <stack-direction>, <text-alignment> - Declares a box. Boxes can contain text and images.
  • name: string
  • stack-direction: stack-vertical, stack-horizontal
  • text-alignment: align-left, align-center, align-right
• define: name - Add text or images inside of a define block, name specifies which box to add to.
  • name: string
• text: <size>, content - Add text to a box.
  • size: huge, title, normal, small
  • content: string
• image: filename - Add an image with the specified filename.
  • filename: string
• end - End a slide or define block.
• template: name - Exact same as defining a slide, except it will not be rendered.
  • name: string
• uses: name - Include a slide or template in another slide. You can then define boxes that are in those slides/templates.
  • name: string

Example of all the above commands in use:

template: "my-template"
    box: "title-box", stack-vertical, align-center
    box: "content-box", stack-horizontal, align-left
end

slide: "slide1"
    uses: "my-template"

    define: "title-box"
        text: title, "Hello World!"
    end

    define: "content-box"
        text: normal, "This is some text."
        image: "yourimage.png"
    end
end

Note: you don't need to use templates, the above code will render the same as this code below:

slide: "slide1"
    box: "title-box", stack-vertical, align-center
    box: "content-box", stack-horizontal, align-left

    define: "title-box"
        text: title, "Hello World!"
    end

    define: "content-box"
        text: normal, "This is some text."
        image: "yourimage.png"
    end
end

You can also use uses: on slides, not just templates, for including full slides inside other slides.

illuscribe <path-to-your-slideshow-file>

By default Illuscribe runs at the same aspect ratio as the monitor it is launched on. If you want a different aspect ratio, you can specify the initial window dimensions like so:

illuscribe <path-to-you-slideshow-file> <window-width> <window-height>

Install the required dependencies:

sudo apt update
sudo apt install libxrender-dev libx11-dev libxft-dev

Clone the repository and compile:

git clone https://github.com/masonarmand/illuscribe.git
cd illuscribe
sudo make install

Now you can run illuscribe on any slideshow file.
