Docusaurus Live Codeblock for Python

NPM Version

[!NOTE]
This theme works with Docusaurus v3+.

[!WARNING] This theme is still in development and the api is not considered stable in the beta phase.

You can create live code editors with a code block live_py meta string.

Install

npm i docusaurus-live-brython # or yarn add docusaurus-live-brython

Modify your docusaurus.config.js

module.exports = {
  ...
+ themes: ['docusaurus-live-brython'],
  presets: ['@docusaurus/preset-classic']
  ...
}

Configure 👉 Brython source:

module.exports = {
  ...
+ themes: [
+   ['docusaurus-live-brython'],
+   {
+     brythonSrc: 'https://cdn.jsdelivr.net/npm/brython@3.12.4/brython.min.js', // default
+     brythonStdlibSrc: 'https://cdn.jsdelivr.net/npm/brython@3.12.4/brython_stdlib.js' // default
+   }
  presets: ['@docusaurus/preset-classic']
  ...
}

Example:

import turtle
t = turtle.Turtle()
t.width(5) 
t.speed(5)
for c in ['red', '#00ff00', '#fa0', 'rgb(0,0,200)']:
    t.color(c)
    t.forward(100)
    t.left(90)

# dot() and write() do not require the pen to be down
t.penup()
t.goto(-30, -100)
t.dot(40, 'rgba(255, 0, 0, 0.5')
t.goto(30, -100)
t.dot(40, 'rgba(0, 255, 0, 0.5')
t.goto(0, -70)
t.dot(40, 'rgba(0, 0, 255, 0.5')

t.goto(0, 125)
t.color('purple')
t.write("I love Brython!", font=("Arial", 20, "normal"))

results in an live editable code block:

Options

A brython live code block can have additional options in the meta string:

  • title=Some-Text The title shown in the codeblock header. The title must be unique per page. Single hyphens/underscores (- and _) are replaced by a space, double hyphens/underscores are replaced with a single hyphen/undescore: title=Foo-Bar--Bazz => Foo Bar-Bazz; title=Foo_Bar__Bazz => Foo Bar_Bazz
  • persistent when added, the reset button will not be shown.
  • slim displays only the play button, without a header and without the option to persist changes.

Storage

User edited code is stored in the localStorage. To lookup the edits, id's for each codeblock are generated after the following rules:

  • title is present -> use a sanitized version as the key.
  • title is not present -> all codeblocks on the page are enumerated and the index number is used as the key. !! Saved Edits are probably not correctly applied.

Development

Ensure to locally link the plugin to the website, s.t. changes take place immediately.

To compile and copy the changed .css files to the lib folder, run

yarn run watch

To see the changes within docusaurus, launch the documentation website located under website/.

Initially link the plugin to the website (only needed once)

# in the project root
yarn link

cd website

yarn link docusaurus-live-brython

Then start the website

yarn run start

Publish

yarn run build
# when running inside wsl, use --auth=legacy
npm login --auth=legacy
npm publish --auth=legacy
