We are excited to introduce KaTeX and embedding support for comments in Hyvor Talk.

## KaTeX

KaTeX is the fastest library for math typesetting developed by Khan Academy. It uses Knuth's TeX format. Therefore, you can write math in comments in the same way you would in MathJax or other libraries.

### Enabling KaTeX

KaTeX support for comments is disabled by default. If your audience prefers writing comments with math, you can enable it from the console.

Go to Console -> Community

Scroll down to Comments Options

Turn on

**Math (KaTeX)**

### Writing KaTeX in Comments

#### 1. Inline KaTeX

You can add inline math notations easily by adding valid KaTeX syntax between `$$`

tags.

Ex:

`1Equation: $$ c = \pm\sqrt{a^2 + b^2} $$`

will be converted to

#### 2. Block KaTeX (Multiline)

If you want to add KaTeX as a block element, you can do it as follows.

`1KaTex Example2` 3$$4\frac{1}{\Bigl(\sqrt{\phi \sqrt{5}}-\phi\Bigr) e^{\frac25 \pi}} = 1+\frac{e^{-2\pi}} {1+\frac{e^{-4\pi}} {1+\frac{e^{-6\pi}} {1+\frac{e^{-8\pi}} {1+\cdots} } } }5$$

This will be converted to:

Start block KaTeX with

`$$`

in one lineAdd your multiline KaTeX

End the block with

`$$`

.

## Embeds

You can now embed content from your favorite sites in your comments!

Hyvor Talk will automatically detect embeddable links and convert them to an iframe or another embed format. All you have to do is to add the link in a new line.

These embeds are currently supported

Youtube videos

Vimeo videos

Giphy GIFs (No need to add them as images in markdown)

Twitter posts

Instagram posts

Facebook posts and videos

Maximum embeds per comment are 3.

Embeds are turned on by default. You can turn them off from the console if needed.

Enjoy the new features! âœŒ

Update: On June 24th, we introduced link previewing as an improvisation for embedding.
