Hi, I was just wondering if anyone could tell me if codemirror6 is backwards compatible with JupyterLab3 or will it only work with JupyterLab4?
codemirror6 is backwards compatible with JupyterLab3
In core, it will only work with JupyterLab 4. It’s possible someone could write an extension that would replace some renderers with codemirror 6 (e.g. notebook cell inputs), but likely not all of them (e.g. settings editor).
There was an attempt to generalize the
ICodeEditor to allow alternate implementations (e.g. to support
monaco integration), but this never really worked out, and supporting two versions of the same library is particularly challenging when the breaking changes are almost total.
