I do not see a discussions tab, but wanted to understand any thoughts towards a SQL Cell? I am still working towards understanding the plugin system, however, I did create a sample notebook using starboard-editor and wa-sqlite here

I am accustomed to the Jupyter Shift+Enter shortcut, which I'm very glad is supported in Starboard. When editing Markdown cells, it seems this shortcut does render the MD, but it doesn't "stop editing". If you go to edit another cell after nothing shows up - it will still be typing it in the already-rendered md cell being previously edited. I also typically edit MD cells by double clicking. From some crude testing I think it's only an issue if all of these conditions are met:

• Firefox browser (83.0 64-bit on Windows)
• Shift+Enter shortcut used to run Markdown Cell
• Advanced Editor being used

When it happens it seems there's no way to stop editing the cell, even if you delete the glitch cell. I end up saving and re-loading the whole notebook.

With gzuidhof/starboard-python#5 , Starboard-Python is going to run in a web worker. Furthermore, it has been designed with the ability to run more kernels for different cell types in the same web worker.

The kernel manager code is still in the starboard-python repository but should eventually be moved to starboard-notebook. Potential features that could be added to it would be

• Running in a SharedWorker that stays alive during development (useful when the web worker doesn't change, makes reloads more instantaneous)
• Interrupting a kernel (relevant pyodide/pyodide#852 and pyodide/pyodide#676)
• Restarting a kernel (relevant pyodide/pyodide#703 )
• Access a shared filesystem

I'm not sure if that's the correct place to report the issue - but when I open https://starboard.gg/#visualization on an iPad the notebook remains empty. On console I saw the error TypeError: Illegal constructor

Everytime I click the run button of the last cell in a v0.8.0 notebook a new cell is appended.

I'm wondering if that's intentional?

Would be nice if it worked. My expectation is that the editor is initially expanded vertically to accomodate the whole cell contents even if in "advanced editor" mode.

I noticed that with release 0.4.0 that insertCell and removeCell throw errors:

TypeError: undefined is not an object (evaluating 'this.insertCell')

and

TypeError: undefined is not an object (evaluating 'this.removeCell')

Insert cell does seem to work if you are inserting a cell at the bottom of the notebook.

These errors still exist in the 0.4.1 release as well.

Reproduce via: js cell. type 1, press alt+enter. type 2, press alt+enter. type 3, press alt+enter, etc.,
What you end up with is this notebook:

Starboard notebooks look super interesting! If things go nicely, I might end up contributing to this project, since it seems like it could be pretty useful for some of my university course tools.

I wanted to ask if you're open to the idea of "reactive" notebooks. Basically, a notebook where cells can depend on other cells and auto-update. (Preferably running the entire user-code in a worker that can easily be killed) This would be extremely useful for more math-oriented notebooks.

Furthermore, I noticed your pull request to pyodide, which I find pretty cool. Since you're already have pyodide, loading sympy is pretty easy. Thus, I wanted to ask if you're also open to adding a mathematical formula editor (probably mathlive) and a fair bit of magic along those lines. Maybe the mathematical formula editor should be done as a plugin or something.

I do have a bit of experience with the math stuff, since I hacked together this.

Hi Guido,

I have been disconnected from starboard.gg a few times today while I was editing notebooks. That was silent as far as I can tell: I only noticed it when I tried to save my notebook (I couldn't). Since you support the export of notebooks (👍) and given that starboard-cli enables to work locally with notebooks with pretty much that same interface (👍), that was only a minor inconvenience!

At this stage, is there a way to push my locally edited notebooks back to starboard.gg?

Cheers,

SB

1. The minify-lit-html-loader caused a ton of issues, so I ended up having to remove it.

3. Replacing node-sass with sass doesn't work, because sass wants Webpack 5. So I had to update to Webpack 5 and upgrade nearly all dependencies...which I suppose should be done anyways.

4. Here are the changes I made on my side. I probably missed a fair number of things that should be done. Also, is there a recommended code formatting style? I'm currently using Prettier, which tends to be rather aggressive.

5. Upon opening the website, it took me way too long to find the teensy tiny "add cell" icon

When I try linking to a section, e.g., [link to section](#section), the link generated goes to the notebook's host rather than the current page. Is there a workaround? Or if not, could you implement this?

I am wondering if you can add a copyfree license also along with MPL.

In https://starboard.gg/nb/ntZSsIp, I have the warning:

Could not set localStorage (key = starboard_notebook_text_editor_preference).

Not a big deal, but any solution / explanation for it?

Is it possible to configure the notebook so that, for example, you disallow js cells, or default new cells to python?

I try to embed starboard as a widget in a property view and I managed to move the <starboard-notebook> element from body to the wanted dom position:

let starboardElement = document.queryselector('starboard-notebook');
mycontainer.append(starboardElement)

However, I have an issue with the checks from crossOriginIsolated.ts.
I import starboard-notebook from

http://localhost:8888/tree/treezjs/node_moduels/starboard-notebook/dist/starboard-notebook.js

and the current url of my app is

http://localhost:8888/lab

Therefore:

location.pathname ="/lab"
scope.pathname = "/tree/treezjs/node_moduels/starboard-notebook/dist/"

and location.pathname.startsWith(scope.pathname) is false, causing an error.

=> How can I disable the cross origin check to avoid following error?

I can't get pass this error

Hi,

On Windows npm run build throw an error because Windows doesn't have the rm command natively.

However, I've managed to build the application running the commands separately, without the rm (I deleted the dist directory manually):

npm run build:notebook
tsc

It is disappearing on hover, but simply moving the mouse over to the menu is often interpreted as moving the mouse off of the menu, so it disappears before user can interact with it. I suspect it may be better to simply disappear on toggle or menu item selection

Starboard Notebook looks like a very exciting project!

Are there any plans to create completely independent stand-alone HTML notebook files?
I've played with starboard-cli, but I'm looking to create completely portable stand-alone reports, with bring-your-own data functionality.

e.g. perhaps an "Export as HTML" button would download a stand-alone HTML file which could be emailed to other people.
Perhaps a subcommand could be added to starboard-cli? Something like starboard build.

I'm imagining a situation where different people have a CSV file on their computer.
I would create a report using Starboard, and send it without the data.
Then, a user could open the Starboard file in their browser, and click a button to load in their local CSV file, and it would automatically generate the report.

At the moment I'm doing this using R Markdown and Shiny, but it's not particularly convenient to create a portable stand-alone R Shiny app.

Is this sort of thing in scope for Starboard?

Hello,
I have noticed that if the page is refreshed several times (to reset my workspace), web assembly runs out of memory and is not able to load Pyodide. I think part of this is that I load a 5 MB dataset to the notebook via JavaScript, then copy it to Python. I can improve that on my side, but also clearing selectively clearing the cache on reload so the the Pyodide executable isn't lost would improve this. I'm not very familiar with this so I'm not much help without some research.

Thanks!

Only just found this but I love it. I believe pyodide released 0.16 and was wondering if there's a way to incorporate this instead of 0.15 into a notebook.

ctrl + enter does still work to insert a new cell below.

In my opinion shift + enter should just move you into the next cell so that the user doesn't shift+enter a few cells of code and then get stuck because they hit a markdown cell.

The cell switching currently doesn't support prosemirror #29

Prosemirror itself doesn't have a concept of line numbers, instead it's tree shaped (like the browser dom) and leaves most arrow key navigation things to the browser. Prosemirror uses contenteditable under the hood.

This makes figuring out if the user is at the top of the document rather tricky. For example, imagine the cursor being placed after the <br>a. Then, while the cursor is in the topmost element, it's not at the top of the document. There is still a <br> before it.

With some work, we might be able to cover all possible cases and implement arrow key navigation. One other approach would be to add a zero-height div at the top of the document. When it gets selected, the cell switching gets invoked.

One alternative approach would be to, when the user presses the up arrow key

1. before anything happens, save the cursor position
2. after the event is over, get the new cursor position and compare it to the old one

Hi Guido,

Any idea why getUserMedia wouldn't work out of the box in the context of starboard.gg hosting?

I end up with a NotAllowedError for https://starboard.gg/nb/nI3Psrm while the same notebook hosted on github pages (https://boisgera.github.io/webcam/starboard.html) works as expected (I am asked for permissions and once granted, I get the stream).

I have the same behavior with Firefox and Chrome (Linux). As far I can tell (but I may be wrong) I have no specific setting in these browsers that would deny automatically the access to the webcam from the starboard.gg domain.

Cheers,

SB

If the user click on "Change Cell Type" button, and after that click on "Cancel" button, the "Change Cell Type" button doesn't work anymore.

I'll take a stab at it when I get the chance (but it may be a little while)

Selecting the link opens a context menu to follow for link:

It would be nice if this could also come up on mouse over of the text. Or maybe open link on ctrl click?

Dear,

I tried matplotlib animation in starboard-notebook, but encountered the following error:

Could you please help me advise this? Thanks!

Attached the sample code for your reference:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.animation as animation

fig, ax = plt.subplots()

def f(x, y):
return np.sin(x) + np.cos(y)

x = np.linspace(0, 2 * np.pi, 120)
y = np.linspace(0, 2 * np.pi, 100).reshape(-1, 1)

ims = []
for i in range(60):
x += np.pi / 15.
y += np.pi / 20.
im = ax.imshow(f(x, y), animated = True)
if i == 0:
ax.imshow(f(x, y))
ims.append([im])

ani = animation.ArtistAnimation(fig = fig, artists = ims, interval = 200, repeat_delay = 0, blit = True, repeat = False)

plt.show()

For example, if you run python: print('Hello world') it will run the cell but the cell contents will become print('Hello world')\n; This happens wherever the cursor is when shift+enter is pressed.

Is there a reason why the release commits aren't tagged (nor published as GitHub releases, for that matter)?

Great project.
I'd like to make a 'plugin' on top of the starboard notebook. However, for this I'd like to run Python code without interacting and displaying it in the notebook cells. So when e.g. a notebook cell contains python code 'x=1' and has been normally run I'd like to access these variables. I know that in Pyodide this is possible by just running running seperate runPython commands to write and read variables ,e.g.:

let pyodide = await loadPyodide({
          indexURL : "https://cdn.jsdelivr.net/pyodide/v0.18.0/full/"
        });
        console.log(pyodide.runPython("x = 9 + 1"));
        console.log(pyodide.runPython("print(x)"));

I know when using the barebones demo it is hard to do this due to the iFrame restrictions. I'm now running StarBoard Notebook without an iFrame and I can access the variable 'runtime' to control StarBoard (I'm aware of the security risks).
So ideally I would run Python code - to extract data from the notebook cells - outside the notebook cells from javascript.
Either directly through Pyodide or through the Notebook's runtime.

When for example using the Python Pandas library in the notebook cells I can extract in the background the column names of a Pandas Dataframe, and display those in a sidebar.

I've been trying to find how to do this from the starboard-python and starboard-notebook source code.
I guess it can be done through 'runPythonAsync' or 'runPython', but I don't know how to access these function from a js script in the browser. (Sorry I'm strong Python and a bit of an JS/TS noob).

I guess to directly access the Pyodide variable it depends also if Pyodide is running in the maintread or in a web worker. Today I was able to access the 'pyodide' variable in the Chrome Console, but somehow I cannot replicate it. I think the notebook was initialized to run python in the maintread.

I guess if the runPython functionality can be exposed through the 'runtime' it would make it possible to create a lof of other creative plugins/ applications on top of this.

When the user hits the escape key Esc, Starboard should focus on the current cell and then enter a "command mode"

Jupyter has a quite well made command mode:

https://www.edureka.co/blog/wp-content/uploads/2018/10/Jupyter_Notebook_CheatSheet_Edureka.pdf

How can I interact with a starboard to
a) observe its cells,
b) run some cells and
c) retrieve info about updated cell output?

=> I am wondering if starboard provides a JavaScript API that better serves my needs.

My aim is to embed some observable notebooks in my application to model scientific data flow pipelines.
If parts of the workflow changes, only the required parts should be updated automatically.

After playing around w/ your codebase, I found that it's not very complicated to convert the parser to use the standard code block marks (```) instead of a custom %%.
All text outside of a code block is considered markdown, and (even though I haven't had a use for it yet) front matter could be its own code block syntax.

``` frontmatter
title: this notes' title
```
# Here's my example

I'm writing markdown
- it's default syntax so it's more universal
- it's about as easy to parse

``` js autoRun
// even though not strictly correct, adding properties after the syntax type doesn't break most parsers
```

So what am I not seeing?

I am working on creating a devcontainer for building starboard, however I am running into an issue. with typescript below. Any suggestions?

The Pyodide version has released some newer versions. Could we update the default Pyodide release that is included in Starboard Notebook? This is currently still on 0.17.0 if I'm correct.

I'm willing to help to achieve this, and maybe submit a PR.

Somewhat related to this: what would be the recommended way of changing the artifactsUrl / indexUrl for Pyodide when hosting a notebook?

An example is rxjs, when importing:

await import("https://cdn.jsdelivr.net/npm/[email protected]/bundles/rxjs.umd.js");

TypeError: global is undefined @https://cdn.jsdelivr.net/npm/[email protected]/bundles/rxjs.umd.js:416:1

The code around that line is:

(function (global, factory) {
    typeof exports === 'object' && typeof module !== 'undefined' ? factory(exports) :
    typeof define === 'function' && define.amd ? define('rxjs', ['exports'], factory) :
    (factory((global.rxjs = {})));
}(this, (function (exports) { 'use strict';

Behavior can be seen by adding a new cell at bottom and selecting menu to change cell type or properties.

Workaround is to add extra newlines to cell or to add many extra cells to be able to make the notebook large enough to see.
Perhaps if the iframe size is too small, call iframe resize to make the iframe large enough to display the menu?

This might be a Pyodide issue, but it seems that Starboard works incorrectly on my new Macbook Pro M1 (Apple ARM sillcon).
In Chrome I get an Error 11 (Crash).

It happens for the normal Python pandas matplotlib demo.
I asked a friend on a non-M1 and it worked all fine (except giving warnings).

Notebook:
https://starboard.gg/#python

It runs until: # x = df.loc[:, ['mpg']]
Then the object turns gray and crashes the Chrome tab.

Tested with Safari, Chrome, and version 12.3

Hi,

When I write the following I get an issue:

When I change it to var then it fixes the issue:

Is there a reason for this?

Many Thanks,

The proxy only listens for changes on the root Cell object, but properties is a child object. Should be an easy fix by making the properties object also a proxy.

When I try to show two matplotlib plots in a page with python kernels, they clash with one another, and a second call draws into the original plot, not in the old plot as expected.

Some libraries, in particular mathjs, can be imported via require but not via import (example usage). Unfortunately, require is not built in. I've tried to load require via import, but that doesn't work. I've also tried to load it via a <script src in an HTML cell, also fails. I've resorted to copying and pasting the entire source of requirejs into a cell so I can then require mathjs - inelegant but it does work. Can we have easier access to require?
