Personally I use JupyterLab the most for my work. The one thing I don’t like about it is the lack of a variable pane. There is an extension for JupyterLab that provides this for Python and R, [Variable Inspector](https://github.com/lckr/jupyterlab-variableInspector/issues/5). Most of the necessary items seem like they could come from the `varinfo()` function in Julia, but it just prints out info. Looking at the source code will take me a bit.

I guess my questions are:

1. How hard would it be to provide at least basic functionality (variable name, type, content)
2. Does somebody who is much better than me at this type of stuff have a desire to put something together?
3. Assuming the answer to the above question is no (makes sense, I brought it up, I probably want it more than most), what would be a good guide for me to put something together? (Such as other source code that does something similar)

I decided to try and make it work. I managed to get one that works (mostly). If you want to help or make suggestions on my probably terrible code, [here is the issue I opened.](https://github.com/lckr/jupyterlab-variableInspector/issues/133)
