A wrapper around MathQuill, a very intuitive math typing editor

npm i -D svelte-mathquill

Add this to your +layout.svelte or any wrapper file where you use MathQuill:

<script>
	import { MathQuillSetup } from 'svelte-mathquill';
</script>

<MathQuillSetup />

This injects jQuery and MathQuill (+ styles) into the head of the document, to begin using MathQuill in your components.

Simple example:

<script lang="ts">
	import { MathQuill } from 'svelte-mathquill';

	let latex = '';
</script>

<MathQuill bind:latex="{latex}" />
<br />
<input bind:value="{latex}" />

autofocus: boolean - if the element should focus on mount

latex: string (bindable & updates) - the content of the element

noBorderOutline: boolean - if styling should be applied to remove borders / outlines. Only use if you have a wrapper that's styled (outlines help accessibility!)

class: string - classes to apply to the math element

config: MathQuillConfig (updateable) - Apply a config to the element.

Triggers when the text is edited: on:edit={latex => ...}

Triggers when the enter key is pressed: on:enter={() => ...}

Triggers when the down arrow is pressed: on:downOutOf={() => ...}

Triggers when the right / left arrows are pressed: on:moveOutOf={("L" | "R") => ...}
