Julia

Julia is a high-level, high-performance programming language for scientific computing. It is designed for numerical analysis, data science, and computational science with syntax familiar to users of other technical computing environments.

Usage

Demo

show code

JS

import { createPlayground } from 'livecodes';

const options = {
  "template": "julia"
};
createPlayground('#container', options);

TS

import { createPlayground, type EmbedOptions } from 'livecodes';

const options: EmbedOptions = {
  "template": "julia"
};
createPlayground('#container', options);

React

import LiveCodes from 'livecodes/react';

export default function App() {
  const options = {
  "template": "julia"
};
  return (<LiveCodes {...options} />);
}

Vue

<script setup>
import LiveCodes from "livecodes/vue";

const options = {
  "template": "julia"
};
</script>
<template>
  <LiveCodes v-bind="options" />
</template>

Svelte

<script>
import LiveCodes from 'livecodes/svelte';

const options = {
  "template": "julia"
};
</script>

<LiveCodes {...options} />

Solid

import LiveCodes from 'livecodes/solid';

export default function App() {
  const options = {
  "template": "julia"
};
  return (<LiveCodes {...options} />);
}

Preact

import LiveCodes from 'livecodes/preact';

export default function App() {
  const options = {
  "template": "julia"
};
  return (<LiveCodes {...options} />);
}

Web Components

<live-codes
  template="julia"></live-codes>

<script type="module">
  import "livecodes/web-components";
</script>

JavaScript Interoperability

Julia programs run asynchronously in a Web Worker. JavaScript can interact with the Julia runtime using the livecodes.julia global:

• livecodes.julia.input — set this to pass input to the Julia script (accessible as livecodesInput)
• livecodes.julia.run(input?) — execute the Julia script, returns a promise with the output string
• livecodes.julia.loaded — a promise that resolves when the Julia runtime is ready
• livecodes.julia.output — the last output string

Live Reload

The Julia runtime is a large download. Initial loading may take some time, after which subsequent runs should be faster.

By default, when code is updated, the environment is re-used. This behavior is used for performance reasons. However, in order to get full reload and start a new environment, insert this comment in the code:

# __livecodes_reload__

Think of this like restarting the kernel in Jupyter notebooks.

This comment can be added in the hiddenContent property of the editor for embedded playgrounds.
