This extension does not yet support the current version of JupyterLab.

[idvorkin]

jupyterlab_vim stopped working on the latest. What can I do to help debug?

(jupyter) ➜  jupyter git:(master) ✗ jupyter-lab --version
1.0.0

(jupyter) ➜  jupyter git:(master) ✗ jupyter labextension install jupyterlab_vim

Would also love to see this extension updated for Jupyter 1.0. I feel lost in my notebooks without it!

[idvorkin]

Started but didn't get very far with #88

[dirkroorda]

I forked and checked whether it works regardless of the version. It did not. A real change has to be made.

[idvorkin]

FYI - I ended up pinning my version of jupyter-lab to avoid losing vim compatibility. I'm not sure what depends on jupyter-lab 1.0 thought:

jupyterlab  = "==0.35.6"  # Pin jupyter lab till vim is compatible

[benlindsay]

@idvorkin Out of curiosity, why/where do you use the syntax jupyterlab = "==0.35.6"? I've only seen it like jupyterlab==0.35.6 in requirements.txt or environment.yml

[idvorkin]

@benlindsay It's from a Pipfile used by pipenv. Pipenv is awesome in theory, except it's really sloooow in practice.

[remiOdite]

Hi ! I just installed jupyterlab, and I get the same error when I'm trying to add this extension. Is there any other solution than removing the pinning of the jupyterlab version ?

[wiseyoungbuck]

I can't believe how dependent on this extension I am. I'm really looking forward to this issue being resolved :).

[zaneselvans]

Me too... though I'm concerned we may need to figure out how to fix it on our own, as @jwkvam has hardly been active at all on Github since the last time the plugin was updated in November of last year. Has anybody else here worked on jupyterlab extensions before?

[dirkroorda]

It seems that the API that Jupyterlab offers to javascript libraries that operate on code cells has changed considerably when going to version 1.0.0. The vim bindings in this extension is really a vim-like editor based on codemirror. The work that has to be done is to re-glue the codemirror library to the jupyter code cell. I guess it is mainly a matter of renaming interfaces and functions in the API. Easy if you have written the code, far from trivial if you see it for the first time.

[ryantam626]

I can look into fixing it on Monday (vacation until then) if no one has done it by then

[willprice]

It appears the CodeMirror vim keymap is now lazy loaded in JupyterLab. Previously it was always imported which this addon has relied on when setting the current cell's keymap.
By importing the keymap in the addon, we ensure it's loaded before setting the keymap of a cell thereby resolving the issue.

I've got a branch up over at https://github.com/willprice/jupyterlab-vim/tree/alpha1 which fixes this. Let me know if you have any issues.

To install...

$ git clone https://github.com/willprice/jupyterlab-vim.git
$ cd jupyterlab-vim
$ git checkout alpha1
$ jupyter labextension uninstall jupyterlab_vim
$ jlpm install
$ jlpm run build
$ jupyter labextension link .
$ jupyter labextension enable jupyterlab_vim

And run jupyter lab.

If you have any issues, please open up the browser console and copy and paste any stacktraces.

[zaneselvans]

Yay! It seems to work fine for me (on jupyterlab 1.0.2) Thank you so much for debugging this.

[willprice]

@zaneselvans thanks for the confirmation it works :) it was fairly easy to debug once I'd figured out how extensions work in jupyterlab.

[louison]

Hi @zaneselvans,
It works for me on jupyterlab (1.02) within docker 👌.
Thank you very much
