Rust implementation of Reveal.js YAML server.
This project is transferred from Python language and now operates in a way that is easier to maintain and release, and it is Rust. Some old functions might be deprecated, and some functions are improved.
This manager downloads the latest Reveal.js archive to provide serving and packing function, and had same licensed as Reveal.js.
Static demo on gh-pages: https://kmolyuan.github.io/reveal-yaml-rs
YAML backend: https://github.com/KmolYuan/yaml-peg-rs (hosted by myself)
Using Reveal.js with Markdown, but it is still difficult to maintain HTML slideshows. This work provides a clean YAML file for your slides, an auto-generated outline, a simple layout function, and a live presentation when editing.
Difference to the before work, the Markdown to HTML translation works by this parser instead of using markdown.js, so there is no more HTML escaping since they will be handled enough. Except for using Markdown recursively in your code block, this needs to use the <code> tags by yourself.
Download CLI executable from GitHub release: https://github.com/KmolYuan/reveal-yaml-rs/releases/
Wherever the binary placed, it should be visible for the environment variable PATH.
If you are a Rust user, install it with cargo:
cargo install reveal-yaml
The executable can be checked with rym --help.
Slides in HTML: In Reveal.js, the HTML structure shown as following. The typesetting is done by original HTML and CSS. ```html
**Slides in YAML**: The horizontal slides are as listed in the second block, which is an array. A slide can work with at least one attribute structure.
yaml
description: ...
The vertical slides work under the `sub` node of first slide, the attributes are same as horizontal slides.
yamlThere are two layout types, called "horizontal stack" (hstack) and "vertical stack" (vstack). The vertical layout is default, as same as HTML.
The stack blocks list in the hstack / vstack tag, and the stack tags can be nested.
yaml
hstack:
- doc: Left
- vstack:
- doc: Right Top
- doc: Right Bottom
The stack tag can add a dollar sign $ to add a borderline between the elements.
yaml
$hstack:
- doc: Splitted left
- doc: Splitted right
The images and resizeable items are support "sized" attribute, which contains three options: src, width and height. The src option is required, otherwise the feature will be disabled or invalid.
The width and height options are the same as the attributes on the <img> tag, they are optional.
yaml
footer: # Footer is a metadata option
src: help/icon.png
width: 50pt
label: Reveal.yaml
link: https://github.com/KmolYuan/reveal-yaml/
img:
- src: img/icon.png
width: 50% # same as width="50%"
height: 70 # same as height="70"
video:
width: 320
height: 240
src: https://www.w3schools.com/html/movie.mp4
autoplay: true
The plugins excluding markdown are enabled by default.
The command rym stands for "Reveal-Yaml Manager".
```bash
rym update
rym new .
rym serve
rym fmt
rym pack ```
Here are the implemented features, or the functions are designed in progress.
Generally, the parser will not check extra key values. In addition, almost all values support the null placeholder to present the default value (blank, ~, null).
Some functions are planed to be demonstrated in the help page. Open the help page by adding /help/ after URL, like http://localhost:8080/help/.
Metadata contains HTML settings and global slide settings.
