Code widgets are a SilverBullet specific “extensions” to [[Markdown]]. Technically, it’s not an extension — it just gives new semantics to markdown’s native fenced code blocks — code blocks that start with a triple backtick, specifying a programming language.
|
|||
|
|
|
|||
|
|
Currently, SilverBullet provides two code widgets as part of its built in [[🔌 Plugs]]:
|
|||
|
|
|
|||
|
|
* `embed`
|
|||
|
|
* `markdown`
|
|||
|
|
|
|||
|
|
In addition, plugs like [[🔌 KaTeX]] and [[🔌 Mermaid]] add additional ones.
|
|||
|
|
|
|||
|
|
## Embed
|
|||
|
|
This allows you to embed internet content into your page inside of an iframe. This is useful to, for instance, embed youtube videos. In fact, there is specific support for those.
|
|||
|
|
|
|||
|
|
Two examples.
|
|||
|
|
|
|||
|
|
First, embedding the silverbullet.md website into the silverbullet.md website (inception!):
|
|||
|
|
|
|||
|
|
```embed
|
|||
|
|
url: https://silverbullet.md
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
and a Youtube video:
|
|||
|
|
|
|||
|
|
```embed
|
|||
|
|
url: https://www.youtube.com/watch?v=VemS-cqAD5k
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
Note, there is specific support for youtube videos — it automatically will set width, height and replace the URL with an embed URL.
|
|||
|
|
|
|||
|
|
The body of an `embed` block is written in [[YAML]] and supports the following attributes:
|
|||
|
|
|
|||
|
|
* `url` (mandatory): the URL of the content to embed
|
|||
|
|
* `height` (optional): the height of the embedded page in pixels
|
|||
|
|
* `width` (optional): the width of the embedded page in pixels
|
|||
|
|
|
|||
|
|
## Markdown
|
|||
|
|
You can embed markdown inside of markdown and live preview it. Is this useful? 🤷 not really, it’s more of a demo of how this works. Nevertheless, to each their own, here’s an example:
|
|||
|
|
|
|||
|
|
```markdown
|
|||
|
|
This is going to be **bold**
|
|||
|
|
```
