Slides Extended

Slides Extended is an Obsidian plugin designed for creating slide decks directly from Markdown notes. Key capabilities include:

• Note Embedding: Use your existing notes as slide content.
• Live Preview: View changes to your slides in real-time while editing.
• Theming & Annotations: Customize the visual appearance and style of your presentations.
• Export Options: Save your slides as PDF documents or HTML presentations.
• Markdown Support: Supports most standard Obsidian Markdown syntax.

The Slides Extended plugin treats horizontal separators (---) and vertical separators (--) inside fenced code blocks (e.g.,

---
key: value
---

) as inert text. These lines will not trigger a slide or sub-slide boundary, allowing you to include code examples containing separators without breaking your presentation flow.

You can include CSS files that resolve relative to the specific deck's directory (rather than the vault root) by using the css key in the YAML frontmatter. Prefix the path with ./ to ensure the asset is looked up in the same folder as the markdown file defining the deck.

---
css:
- ./local.css
---

You can use a specific slide template to ensure math formulas are rendered as inline-style equations regardless of your global 'show grid' settings. Use the [[template_formula]] template syntax in your slide comment.

To use this, add <!-- slide template="[[template_formula]]" --> before the slide content and wrap your math in a ::: formula container.

<!-- slide template="[[template_formula]]" -->

## Slide Title

::: formula
$$\lim_{t \to \infty} (w(t) - y(t)) = 0$$
:::

Slides Extended supports LaTeX math rendering using both inline and display math syntax.

• Inline Math: Use single dollar signs $ ... $ to render math within a line of text.
• Display Math: Use double dollar signs $$ ... $$ to render math as a standalone block.

Note that the visual rendering of display math (e.g., the position of limits like $\lim_{t \to \infty}$) may change depending on whether the 'show grid' setting is enabled in your presentation settings.

$\\begin{vmatrix}a&b&c\\ d&e&f\\ g&h&i\end{vmatrix}$

$$\\lim_{t \to \infty} (w(t) - y(t)) = 0$$

$$
$\begin{cases}
2x_1^2 + x_2^{2} \leq 10 \\
x_1 + 3x_2 \leq 15 \\
x_1, x_2 \geq 0
\end{cases}
$$

If you use the BRAT plugin for managing beta or GitHub-based plugins:

1. Ensure BRAT is installed.
2. Open the Obsidian command palette (Ctrl/Cmd + P).
3. Run the command BRAT: Add a Beta Plugin.
4. Enter ebullient/obsidian-slides-extended as the GitHub repository.
5. Restart or reload your vault once the installation is complete.

The <grid> component allows you to position elements on a slide using drag, drop, and style attributes, as well as background and padding settings. This is useful for placing callouts or other content in specific areas of the slide.

Key attributes:

• drag: Starting position.
• drop: Target position.
• bg: Background color (e.g., white).
• pad: Padding (e.g., 50px).

<grid drag="30 30" drop="11 68" style="font-size:36px">
> [!example]
> Here is an Example for an Callout in a Slide.
</grid>

<grid drag="50 100" drop="50 0" bg="white" pad="50px" style="font-size:36px">
> [!cite]
> Here is an Cite for an Callout in a Slide.
</grid>

Slides Extended supports standard Markdown syntax including emphasis, bold, highlight, strikethrough, and triple emphasis.

It also supports Obsidian-style Callouts (e.g., [!danger], [!warning], [!tip], [!error], [!example], [!cite], [!note]). Callouts can contain nested Markdown elements like emphasis and bold text.

Note: Unordered list fragments (using - or +) work within callouts, but ordered lists do not support this fragment behavior.

_emphasis_ **bold** ==highlight==  ***triple***  

> [!danger] Attention *for ==real==*!
> _emphasis_ **bold** ==highlight==  _**triple**_

> [!tip] This tip has a custom Header
> This is an Tip with a custom Title

You can embed remote video and audio files using standard Markdown image syntax ![alt text](url). The plugin interprets these as media elements.

Images can be embedded using standard Obsidian syntax ![[image.png]].

Ordered lists using the 1) , 2) syntax are supported for slide numbering.

Unordered lists using - or + are supported, including fragments within callouts.
