[jupyter] Create beautiful reactive GUIs for Python packages using Markdown and a few custom HTML elements

[Simon Biggs]

Scripted Forms


https://github.com/SimonBiggs/scriptedforms


Quickly create beautiful reactive GUIs for Python packages using Markdown 
and a few custom HTML elements. Under the hood it uses the Jupyter Notebook 
server, Angular, Angular Material, Phosphor and JupyterLab.


Display is based upon the cell output within JupyterLab's notebook so most 
items that display within the notebook should work here.


To quickly take it for a spin write:


pip install scriptedforms


Then open a python prompt (not an ipython prompt) and copy in the following:


import scriptedforms as sf
# workaround for https://github.com/SimonBiggs/scriptedforms/issues/24def 
create_file(filename, contents):
with open(filename, 'w') as f:
f.write(contents)

filename = 'quick-start.md'
markdown_contents = """# An 
exampleyour_name`print('Hello 
{}!'.format(your_name))`"""

create_file(filename, markdown_contents)
sf.load(filename)


See https://github.com/SimonBiggs/scriptedforms for how you can then edit 
the resulting markdown file and how you can use Scripted Forms to quickly 
make GUIs for your python package utilities.


Cheers,

Simon

Re: [jupyter] An example of what can be built with the JupyterLab ecosystem

[Simon Biggs]

Hi Fernando,

Thank you for the encouragement. Really chuffed that you want to include 
what I have done as an example in the talk you are giving. Puts a huge 
smile on my face. My supervisor was also quite impressed.

I shall re-post the link with a bit more prominent detail.

Thanks again :).
Cheers,
Simon

You're most likely experiencing this:

- https://github.com/jupyter/notebook/issues/3248
- https://github.com/jupyter/notebook/issues/3263

with notebook 5.3.1, sorry.  If so, an upgrade to 5.4.0 will solve the
issue:  https://github.com/jupyter/notebook/pull/3264.

Cheers,

[jupyter] Creating a new notebook inconsistent between home screen and within active notebook.

[Mark Murphy]

So normally when I try to create a new notebook I will go to the directory 
that I want the notebook and select "New" on the right side of the screen 
and "Python 3" for a new notebook.

However after several updates I have noticed that when I do this the new 
notebook is created in the Jupyter start directory rather than the 
directory I am currently showing in the home page. No matter what folding I 
am in, it will always just create the new untitled document in the base 
directory. This is not just for Python but R NBs as well.  

There is a second way to make a new notebook. And this is from an already 
opened notebook. "File" -> "New Notebook" if I do this, then the new 
notebook is created in the same folder as the current notebook. 


Any ideas why the "New" option on the Home screen wont use the current 
directory? Any ideas how to reset this? 

Thanks

Mark M

Re: [jupyter] How to know which config file is being used?

[Nate L.]

It ended up being a chrome extension called Vimium, which seems to 
overwrite shortcuts for a lot of sites.

 Is the search bar something from a browser extension? If it captures 
 the key event before we get it, there's not much we can do about that.

No prob from me, always good to highlight how folks are adopting the JLab
architecture for new and productive uses (I'll actually try to include this
as a great example of this practice in an upcoming talk of mine where I'll
spend some time on JLab as a modular architecture that we want wide
adoption for :)

You are so right.  I tried using this with Safari and everything works as 
expected. I'll look into what extension in Chrome is getting in the way and 
report back if I find out what it is.

Thanks, Takowl!

 Hi Takowl,

 Yea, I'm in the *notebook* command mode. Upon uninstalling the Vim 
 extension, I can now add cells with 'a', but that's about it. When I press 
 'b', I get the search bar pop-up:


 


 Not sure what's wrong. Maybe I should reinstall jupyter?  The problem 
 with reinstallation is that there are so many ways to uninstall it that I 
 don't know which would be optimal for my case.

Sorry, I've never seen it before. If you don't know you've installed an
extension, chances are it's something built into your browser.

Re: [jupyter] How to know which config file is being used?

[Thomas Kluyver]

Reinstalling probably won't make a difference to issues in the browser like
that, though it's always possible.

Is the search bar something from a browser extension? If it captures the
key event before we get it, there's not much we can do about that.

 If you're having some trouble, scatter some console.log('A') calls
 around (with different letters) and then look in your browser's Javascript
 console to see which bits are getting run.

Re: [jupyter] How to know which config file is being used?

[Nate L.]

Hi Takowl,

Yea, I'm in the *notebook* command mode. Upon uninstalling the Vim 
extension, I can now add cells with 'a', but that's about it. When I press 
'b', I get the search bar pop-up:




Not sure what's wrong. Maybe I should reinstall jupyter?  The problem with 
reinstallation is that there are so many ways to uninstall it that I don't 
know which would be optimal for my case.

You’re doing everything right, there’s just some zmq magic that’s getting
in the way of things behaving clearly. The short answer to your question is
that it’s never to early to send a shell request. zmq is ‘connectionless’
which is the zmq way of saying that you can send messages even when the
other end hasn’t shown up yet. It will handle delivering the message when
the kernel shows up. This is why POLLOUT is true immediately. What you are
likely running into is a failure to propagate subscriptions on the PUB/SUB
channel. If a PUB socket sends a message and it has no registered
subscribers, it will discard those messages immediately. And propagating
those subscriptions takes a finite amount of time.

So the common failure is:

   1. request kernel start
   2. send request immediately
   3. kernel starts, binds, handles request, sends replies
   4. PUB/SUB subscriptions haven’t propagated, so PUB messages are
   discarded
   5. zmq PUB/SUB subscriptions finish propagating (too late!)

The way we deal with this is explicitly waiting for IOPub messages to be
delivered before sending requests. This is implemented in
BlockingKernelClient.wait_for_ready. But the logic is:

   1. send kernel_info_request
   2. wait for reply
   3. wait for status: idle on IOPub

if reply came and idle didn’t, IOPub subscriptions may not have propagated,
run again. This typically takes ~milliseconds, so the second try will
always work. Here’s a script
 that starts a
kernel and connects a client to it and runs a bit of code.

Re: [jupyter] Android Native FrontEnd for Jupyter Notebook

[Thomas Kluyver]

We have a 'powered by Jupyter' logo which we encourage projects to use, but
it doesn't lend itself to combining with other things. So if you want to
design an alternative Jupyter motif to use for such logos, go for it!

(Unfortunately, I don't know where you can get the 'powered by' logo except
by snipping it out of the brand guide PDF. Could someone who has it put it
into the jupyter/design repo?)

Re: [jupyter] How to know which config file is being used?

[Thomas Kluyver]

It can be tricky to get custom.js to load things at the right point. Have a
look at the examples here to wait for promises:
https://github.com/jupyter/notebook/blob/master/notebook/static/custom/custom.js

If you're having some trouble, scatter some console.log('A') calls around
(with different letters) and then look in your browser's Javascript console
to see which bits are getting run.
