# reveal-hugo

A Hugo theme for creating [Reveal.js](https://revealjs.com/) presentations that allows you to put multiple slides in the same markdown file.

The motivation behind creating this theme is pretty simple - I didn't want to have to manage one markdown file for every slide, which would add the overhead of coming up with a file name, setting a `weight` param in the front matter to keep it in order, etc, all for just a few lines of text. Instead, I like to organize groups of slides into a smaller number of markdown files, each representing a section of the presentation.

### Example

Using reveal-hugo, a three-slide presentation can be created with just one markdown file, like so:

```markdown
# English
Hello.

---

# Français
Salu.

---

# Espagñol
Hola.
```

The only requirement is to demarcate slides with `---` surrounded by newlines.

# Demo

Visit [https://reveal-hugo.netlify.com/](https://reveal-hugo.netlify.com/) to see an presentation created with this theme that shows more ways to use it.

# Usage

To create the presentation, the theme will look for all Hugo pages that have a type of `reveal`. That means they're in a `reveal` directory in the `content` folder OR the type is manually set to `reveal` in the front matter.

```toml
type = 'reveal'
```

Use the `weight` param in the front matter to specify the order that the pages should appear in the presentation.

```toml
weight = 20
```

### Fragments

Fragments are a Reveal.js concept that lets you introduce content into each slide incrementally. Borrowing the concept from [hugo-theme-revealjs](https://github.com/RealOrangeOne/hugo-theme-revealjs), you can use a `fragment` shortcode to accomplish this in reveal-hugo in the same way.

```markdown
# Let's count to three...
{{% fragment %}} One {{% /fragment %}}
{{% fragment %}} Two {{% /fragment %}}
{{% fragment %}} Three {{% /fragment %}}
```
