A standalone embedding of the FOSS drawio / mxgraph package into jupyterlab

jupyterlab-drawio's Issues

"http://localhost:8888/src/css/common.css" was blocked

When the drawio extension is enabled the following files are requested over the network:
http://localhost:8888/src/css/common.css

But in JupyterLab 2.1.1 I get the following error in the web-console of Firefox:
The resource of "http://localhost:8888/src/css/common.css" was blocked because of a MIME type conflict ("text/html") (X-Content-Type-Options: nosniff)

Import or Paste images into diagram

Would be great to be able to paste images into a diagram, like you can with the standalone Draw.io app, or in other places (like Confluence) where Draw.io is embedded.

Pages menu at the bottom missing

Create plugin! I wonder if I am missing something. When using draq.io I have at the bottom a pages menu.

I don't have it with the plugin. It would be helpful for me.

Compability to JupyterLab 2.0

Hello,
currently the extension is not compatible to JupyterLab 2.0,
could this be fixed?

Automatically creating alternative document formats from .drawio files

A recent release (10.7.5) of draw.io adds command line support that looks as if it lets you run export commands from the command line.

Picking up on Jupytext, which uses the Jupyter content manager to maintain "paired" equivalents of documents (for example, an .ipynb notebook file and a markdown equivalent of it), I wonder if it would be useful to support a similar sort of behaviour for jupyterlab-drawio in which saving a drawio file also results in the automatic creation of an SVG exported version of it, for example?

To keep things tidy,, Jupytext allows you to set watchers on different directory paths so that files of a particular type updated in a specified directory are automatically dualled by equivalent documents of other file types in other directories (mwouts/jupytext#180). In the drawio case, this might mean providing an svg directory into which .svg equivalent filed are automatically exported whenever a drawio file is saved?

Shifted tooltip location

While trying out this cool extension for the first time I saw that the tooltips were pointing at the wrong place.

If I collapsed the file browser the tooltip would get closer but it was still shifted.

jupyterlab-drawio 0.5.0
jupyterlab 0.35.4

Save digram (mac OS) '_xsrf' argument missing from POST

Click save opens a new tab with the above error.

JupyterLab 0.33 support

I'm about to upgrade to the latest JupyterLab and it would be great if the drawio extension would work with that

0.35.0 support

Is this yet available on jupyterLab 0.35.0. I have upgraded from 0.34 and in 0.35 it is not yet supported.

mxgraph library update - 4.0.3

Fixes most of the layout issues related to scaling, and FF-specific bugs. It's worth updating.

Embed into a Jupyter Notebook

Hi!
Thanks for a great plugin.

I have a request -
I know it's possible to export and to embed the PNG, but it'd be great to embed the diagram itself which may be editable inside the notebook or that will open the editor on double-click.

Thanks!

JupyterLab 0.33 breaks jupyterlab-drawio

Work computer got re-imaged, rebuilding everything. This lovely package seems to be giving me some grief though (was working perfectly before):

FWIW, I also have:

$ jupyter --version
4.4.0

Any suggestions greatly appreciated.

EDIT
I fixed this by downgrading to to jupyterlab 0.32, but I'm going to leave this open for the moment as turns out that 0.33 just made it to PyPi and also seems to break jupyterlab-drawio

Compatibility with jupyterlab 2.x?

Our notebook images are based on dockerstacks which now uses jupyterlab 2.0.1 -- however, when installing drawio, there's a version incompatability.

I don't know enough about the API differences between jupyterlab 1.x and 2.x versions -- is this a simple fix?

Installation hangs on MacOS

I am on MacOS 10.13.4. Here are my settings.

• npm 6.0.1
• node 10.0.0
• python 3.6.4
• conda 4.5.3
• pip 10.0.1
• jupyter 4.4.0 (from jupyter --version)
• jupyter 1.0.0 (from pip list | grep jupyter)
• jupyterlab 0.32.1 (pip list)

I followed the installation instructions jupyter labextension install jupyterlab-drawio and the for development (clone the repository, then npm install, ....). However, I seem to always get stuck on downloading or processing some tgz file. I have no idea what this file is. Using the dev installation method, which I thought would avoid downloading anything since I think it's building from source, it hangs here

I cleared the pip and npm caches.

• rm -fr ~/Library/Caches/pip/http
• npm cache clean --force

None of this helped.

Any ideas on what's going wrong here?

Can we have an option to change transparency of objects?

Additional libraries

Is there now, or will there be a way to enable additional draw.io libraries? I suspect this is in the works already, just opening an issue so I can keep up with updates. This is an awesome addition to jupyterlab, thanks for your work on it!

Bug: Export doesn't work with JupyterHub

Jupyterlab file browser view is broken after installing jupyterlab-drawio

I have a jupyterhub 1.0.0 running with jupyterlab 1.0.2.
After installing jupyterlab-drawio all entries in the file browser in jupyterlab are invisible. The gray background while hovering over a line with the mouse is about 1/3 of the original line height.
Clicking on different parts switches to the next folder or opens the selected file. Just the visibility is gone.

Feature request: Link shape to object in kernel

Vision:
Developer/Data Scientists want to document a complex task in a graphical way. After they wrote their code, they open the draw.io extension and select the running kernel. Now they can draw a shape and link it to an object in the kernel (Probably identified by the object name and/or type). The logic link is maybe indicated by a small green check mark at one corner of the box. Now they can sketch their pipeline/process with several objects.
When an object is removed from the code and not present in the kernel anymore (Probably after a kernel restart) a red cross in the shape indicates the absence of the object, signalling the users that their sketched pipeline is not consistent anymore, forcing them to review their code or to adapt their sketch.

Needed components:

• A dropdown to select a running kernel
• A dropdown in the shape properties to select the object
• Checkboxes to check for object properties (Name, Object type, ...[attributes?])
• Visual indication at shape whether object with properties is found in kernel.

Notes:
The general absence of a graphical sanity check and documentation tool is a big weakness of the jupyter workflow. I think draw.io could pretty easily carve out this niche with their existing tools and make a really big difference to data scientists workflows.

The filename of exported svg associated with the original dio filename maybe better

The filename of exported svg to be the same as the original dio filename maybe better, so that it can be convenient when we edit the dio file and reference the exported svg file in .ipynb. Or can we render the dio file directly from .ipynb?
The current svg filename generating machanism is named after untitled[\d].

I think we don't use the standardized messaging protocol this library provides for embedding in other applications, to make the save menus seamless, etc. It would be great to look into using the embed mode: https://desk.draw.io/support/solutions/articles/16000042544-embed-mode

Npm 5.8.0

(these are both installed with current jupyterlab apparently)

$ jupyter -v

jupyter core     : 4.5.0
jupyter-notebook : 6.0.1
qtconsole        : 4.5.5
ipython          : 7.8.0
ipykernel        : 5.1.2
jupyter client   : 5.3.3
jupyter lab      : 1.1.4
nbconvert        : 5.6.0
ipywidgets       : 7.5.1
nbformat         : 4.4.0

fishy behaviour with Text items

Hey there

First off I'd like to congratulate you guys for this great tool, hopefully I won't need to digress with keynotes any more :-)

Now, I'm using this version

$ jupyter labextension list 2>&1 | grep drawio
        jupyterlab-drawio v0.7.0  enabled  OK

but am facing an odd behaviour with text items; creation is fine, but editions later on turn out to be problematic

I have tried to describe a scenario that would allow to reproduce my issue, but I could not find anything deterministically reproducible; so the best I can describe it is, it happens that I open a document to change the contents of a text element, but that does not trigger properly and does not survive the next save/reload cycle; also when the problem occurs I often see erroneous display.

this is not an isolated occurrence, I have run into that a few times already; at first I could be misusing the UI, and it's still possible that I do, but figured it was worth recording the matter in case others would experience the same thing

thanks again for making this tool available !

Unable to install on Mac OS

Hi, I'm not very Terminal or Jupyter savy...

I've tried:
jupyter labextension install jupyterlab-drawio

Then got this:
> '' pack jupyterlab-drawio expected str, bytes or os.PathLike object, not NoneType

Error during install

Error in installation. When I try to install using
$ jupyter labextension install jupyterlab-drawio

I get the following error.

/usr/local/bin/npm pack jupyterlab-drawio
jupyterlab-drawio-0.1.2.tgz

Errored, use --debug for full output:
IOError: CRC check failed 0x4231cfac != 0xc08de80bL

Would appreciate your help.
Thanks

405 : Method Not Allowed when "save"

Hello,

I have an issue with this extension on JupyterHub + JupyterLab when I want to save the work.

The URL is : http://xx.xx.xx.xx:8000/save
405 : Method Not Allowed

Thx

Allow exporting into more formats

The online draw.io app supports more formats, whereas only SVG is available as an export option. At least include PDF and PNG, which can be easily embedded in Latex.
