Inline diffs

[jtpio]

It would be great to also have the option to show inline diffs, directly in the cell.

Which could be implemented in a separate plugin and command.

Here is a quick proof-of-concept with the @codemirror/merge unified view:

jupyterlab-cell-diff-unified.mp4

[jtpio]

There is also https://github.com/jupyterlab-contrib/jupyter-suggestions, which displays inline diffs but with the diff library: https://www.npmjs.com/package/diff

Using a custom codemirror extension: https://github.com/jupyterlab-contrib/jupyter-suggestions/blob/main/packages/base/src/suggestionsPanel/cmExtension.ts

Maybe this should be moved here in this repo as another option for cell diffs, and then have jupyter-suggestions depend on jupyterlab-cell-diff.

I love this idea @jtpio! Can we move some of this code over from jupyter-suggestions?

Can we move some of this code over from jupyter-suggestions?

I haven't looked to much into the details, but otherwise yes the idea would be to extract all diffing from jupyter-suggestions and move it here.
