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

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

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.

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