Imagine a presentation tool that seamlessly blends simplicity with power. Welcome to Dough – your new favorite presentation companion. Say goodbye to clunky interfaces and hello to a tool that’s as intuitive as it is efficient.

Why Dough?

(Why, though? - Get it? xD)

At StackIt, the team gathers every Saturday for their weekly showcase. Each member presents their progress, showcasing the fruits of their week-long hike. Inspired by this collaborative spirit, I came to the idea of Dough - a presentation generator tool like no other. Built in Rust, Dough is a rich, modular, command-line tool to generate presentations. I found similar tools like slidev by antfu and presenterm that inspired me to create Dough.

Features

• Dough’s modular design allows for seamless customization. You can customize the color scheme, the alignment, and the syntax highlighting of the code blocks, and even the runtime of the code blocks.
• Align content both horizontally and vertically and also specify the alignment of individual text segments. You can decide between having a margined presentation or one without margin anywhere, in the bottom, left, or centre, of the screen.
• Code blocks have syntax highlighting, and also support code execution. You can run your code and the output will be displayed in the presentation. The code blocks run in a separate thread and the main thread displays the output in the terminal. The code blocks are internally ordered in the order they appear in the markdown file.
• Dough will also be supporting images in the terminal for the ones that have a GPU-enabled terminal like Kitty or iTerm2.
• You can choose to use templates. The optional --template flag is used to specify the template. The default template is used if not specified. If not, simply spawn a new folder and a markdown file, and you’re good to go. Dough’s intuitive navigation system lets you scroll through slides with ease. You can choose between scrolling top-down or bottom-up. Presentations start from 1 to the last slide. Dough supports arrow keys and VIM keybindings to navigate through slides. There are two modes of navigation:

1. Highlight a line as you scroll through the slides.
2. Scroll through the content of the slide.

• Dough supports hot reloading. You can edit your markdown file and do a ctrl+r to reflect in the presentation instantly. The auto hot reload is still in the works.

The default style settings are stored in a style.yaml file which looks like this: style.yaml

Unveiling the Core

Dough thrives on markdown, transforming simple text files into captivating slides. Leveraging the syntax of pulldown-cmark, it effortlessly transforms your ideas into visual stories.

Projects are created by simply writing a markdown file inside a folder. The folder name is the name of the project. Just mkdir my_folder and touch my_folder/1.md and you’re good to go. You can also use templates using the new command. The slides are presented using the present command. The optional --template flag is used to specify the template. The default template is used if not specified.

At the heart of dough lie two pivotal components:

• Renderer: This component takes charge of the visual rendering of slides.
• Parser: Responsible for dissecting markdown files and converting them into a structured format.

The parser parses the markdown file, prettifies it, and then passes it to the renderer to render it. The renderer then renders the slide in the terminal to display it.

The parser takes in the markdown text and converts it into Nodes of mdast(markdown abstract syntax tree). The tree is reccursively traversed and each node is then styled according to the Node ( Markdown Element ) type. After combining all the nodes, a prettified version of the text is returned. It then modifies the prettified content, applies custom alignment, styles, and spacing, and adds a margin to the content to fit the terminal.

There are two stages of rendering:

1. The renderer takes in the prettified content and renders it in the terminal.
2. The renderer then handles the navigation actions, the scrolling mechanism and the keybindings. It controls the flow of the presentation and is responsible for rendering the slides in the terminal. It switches between presentation and highlighting mode and also handles the code execution.
