Ultimately, how do Jupyterlab page_config settings get loaded? I'm trying to move to JL 2.x. I am running under K8s. I have a custom service set up inside my K8s cluster to provide access to the Hub API. Under JL 1.x I could set JUPYTERHUB_API_URL and Lab could talk to hub, but I was using jupyter-labhub. I understand that in 2.x Hub support has been folded into core JL, but it doesn't seem that the Lab is ever establishing contact with the Hub and saying "hey, I'm ready for you."
I am presuming this is getting loaded via a jupyter config setting, but I am not having any luck finding the appropriate one.
If I want to override an internal component, in this case the Launcher. How do I prevent the original component from activating and generating errors like this:
Plugin '@jupyterlab/launcher-extension:plugin' failed to activate.
Error: Command 'launcher:create' already registered.
at CommandRegistry.push.lBOR.CommandRegistry.addCommand (index.js:123)
at activate (index.js:36)
at index.js:156
at async Promise.all (:8889/index 60)
disable the built-in extension
Is there a convenience function to parse and display traceback(in ANSI code) from KernelReplyMsg for display in custom widget? The only ansi parse I could find was in
Can't quite find how
rendermime/src/renderer, which has a function called Private.ansiSpan but it's not exported...Can't quite find how
OutputArea renders it unfortunately.
I have a question about theme: After I installed a theme extension, the newly installed theme won't appear in the Settings -> JupyterLab Theme submenu. How can I fix this?
Well it turned out to be a problem described in this issue jupyterlab/jupyterlab#8122 . I deleted build_config.json and everything works fine!
lookin at jupyterlab/jupyter-renderers#3
I see https://jupyterlab.readthedocs.io/en/stable/developer/virtualdom.html but no code
to go back, all I'm trying to do is to have a dropdown + another component inside a component
I know how to do this with plain DOM, or with react
trying to find out how I would with JupyterLab
@yuvipanda maybe this? https://github.com/jupyterlab/extension-examples/tree/master/react/react-widget
do you think this should be made more visible in the docs? for now there is a link to the repo on the
latest version of this page: https://jupyterlab.readthedocs.io/en/latest/developer/extension_dev.html
@jtpio I think it should be in https://jupyterlab.readthedocs.io/en/latest/developer/virtualdom.html. Also, I see there's a bunch of 'literalinclude' with code snippets that aren't present in the rendered output
IMO that would've been of big help
@jtpio works on my local build but not on RTD, latest or stable
@jtpio I filed jupyterlab/jupyterlab#8473
This feels like it should be fairly simple but I've not found anything at all in the docs
actually I think I can just take lumino out of the equation completely and go pure react
there isn't really any lumino need there
maybe the cell type dropdown in the notebook toolbar can be useful as reference: https://github.com/jupyterlab/jupyterlab/blob/b62d4fd463c6d00451df6327203413cf1b520a8f/packages/notebook/src/default-toolbar.tsx#L243-L308
I like it
also looks like it doesn't depend on anything within JupyterLab itself
otherwise it should be possible to import from apputils in standalone applications outside of jupyterlab with
import { ReactWidget } from '@jupyterlab/apputils';
