Dr. Aono, thanks for your efforts! toStringX3D is passed an indent level, I believe Don suggests 2. That’s how far the hierarchical indentation in the produced XML code goes (number of “tabstops” in a way). You can probably also use 0, but not sure.
<a class="m_-6992373326001183697m_-1147013873556976865moz-txt-link-freetext" href="http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/Core/X3DObject.html#toStringX3D-int" rel="noreferrer noreferrer" target="_blank">http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/Core/X3DObject.html#toStringX3D-int</a>-
so you would use it like this:
str0 = X3D0.toStringX3D(2)
Then proceed with the returned string as XML (parse, add closing tags per Andreas’ code, etc).
Please capture what you did to create a pip package or conda package and the installation process so we can publish amongst ourselves and other interested parties, thanks!
I apologise for the late reply, my thinker gave up for a while I guess.
So 4 more action items:
Use toStringX3D in your code
Use Andreas’ code to add any closing tags
Document how to create an installation package for x3dpsail and how to install.
Loren, look at Masaki Aono’s previous post and comment on if we did imports and import references correctly (4 should precede 3)

Dr. Aono,
Thank you for your testing and installation efforts. I think the next step is to copy/paste the HelloWorld.py into the Jupyter notebook and see if it builds and exports XML correctly, similar to Andreas Plesch’s binder, <a class="m_-6992373326001183697m_-1147013873556976865moz-txt-link-freetext" href="https://mybinder.org/v2/gh/andreasplesch/conda/master/?urlpath=lab/tree/sphere.ipynb" rel="noreferrer noreferrer" target="_blank">https://mybinder.org/v2/gh/andreasplesch/conda/master/?urlpath=lab/tree/sphere.ipynb</a> but with the package import as you have, and package prefixes found in HelloWorld.py. The only thing we’re testing in this step is the “x3dpsail” namespace inside jupyter. Whereas Andreas’ solution had no package. Ideally, I’d like to get Loren’s signoff on what we’re doing re: packaging and imports after the notebook is published again.
You’ll have to change the toFileX3D to toStringX3D in HelloWorld.py to get the xml into the page (instead of doing the file open). There are a couple of more XML strings you’ll have to add per Andreas’ notebook. There may also be an issue with trusting the X3DOM javascript url.
See X3DObject (X3D in python) Javadoc here for toStringX3D method:
<a class="m_-6992373326001183697m_-1147013873556976865moz-txt-link-freetext" href="http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/Core/X3DObject.html" rel="noreferrer noreferrer" target="_blank">http://www.web3d.org/specifications/java/javadoc/org/web3d/x3d/jsail/Core/X3DObject.html</a>
We should probably collect a series of Jupyter notebooks into a test suite. Something else to research.
I am sorry if this seems very basic. It takes small steps to get a long distance. We really need to gather this information into a wiki or web page (or jupyter notebook!)

Dear all,
I think I could install x3dpsail.
C:\Aono\ISO-2019\Python\John\pyjnius>pip freeze | grep x3dpsail
x3dpsail==0.1
Then, I did as follows:

Dr Aono, Don, Andreas, Loren,
I have attempted to collect items necessary for building a x3dpsail package in the GitHub repository:

If I was able to find you as an email address or user in the GitHub database, I added you as collaborators
We need, I believe:
A pip package
A conda package
A mybinder package
A conda-forge package
Please check your various attempts and successes to create packages into this repository. Also modify README.md to include instructions.
I have added a HelloWorld.py which should run under all packaging techniques I hope.
I would hope we could find a way to add our package to any activated conda environment.
What I would like to have is the ability to release this folder as an “X3DPSAIL release” and maybe have Travis CI (or similar) deploy the release to various package repositories.
If you know someone with CI experience (I have some, but it’s nearly a decade old, with Java) who is willing to help, that would be terrific (Do they teach CI in schools?) Let me know and I will add them. I think we have a fairly simple release. The only complication is the jar.
I will go back to reading recipes, etc from Andreas’ posts.
Thanks,
John

Dear John and all,
Thank you.
Actually I did svn cleanup and update, which did not solve my problems.
But, yes, I think I could download the necessary sub-folders.
I haven't yet downloaded x3d/content/examples/X3dForWebAuthors folder.

If svn checkout abends, you can cd to the folder, then run

You need the specifications folder, the stylesheets folder, the tooltips folder, and the x3d/content/examples/X3dForWebAuthors folder, I believe for a clean build.
