Ability to run all cells from the top or above/below the current cell

[puruzio]

It will be handy to have an option to rerun a range of cells in the notebook automatically, initiated through a button or menu item. (See Jupyterlab example in the image below)

I'm aware of the option to enable automatic refresh by cell in Livebook, but I couldn't find a way to do it the way I described above.

In Jupyter each cell can be run alone and in any order, so running all above is mostly to reproduce certain execution (though there's still global state that may affect it). In Livebook's model all cells run sequentially top-to-bottom, so if you evaluate a cell, all cells above that are changed/stale/new get evaluated automatically. In this context running all above isn't exactly that useful.

If you want to effectively reset the whole session and run all cells up to the focused one, you can do 00 (restart runtime) and then cmd/ctrl + enter (evaluate current, and hence all above). There's also cmd/ctrl + shift + enter to evaluate the whole notebook (or reevaluate stale cells).

If none of this works for you, please elaborate on the use case :)

Oh... those keyboard shortcuts would give me what I need. Thank you for your lightning-fast response and all your great work on LiveBook!

Sweet, for more shortcuts do ? or click the keyboard icon in the session sidebar :)
