Tweak limit of cell results

[rodrigues]

Many times when the resulting data is a bit big (but often not that big), livebook result cells show results limited with ellipsis ...

I often have to write a |> IO.inspect(limit: :infinity) or similar to bypass this issue and explore the full data, dbg also shows limited results.

I wonder if it's possible already, or if it would be feasible to configure that for a notebook, an env variable could also work perhaps? Maybe this would be better as a cell option instead?

It would be also interesting to be able to resize the cell result height at the border.

Thanks!

Hey @rodrigues, you can use Kino.configure/1 to set default inspect options at the top of the notebook :)

Amazing, thanks!

Hi @jonatanklosko for some reason Kino.configure/1 does not always work. I set in the "Setup" section to no avail. I have to call Kino.configure/1 in the same cell for it to work.

Any idea how to solve this?

Oh, that's not related to inspection, Livebook limits text output to 1000 lines.

So, is there any way to circumvent that limitation?

You could set width: 1000 (default is 100) to fit more in a single line, so that the output is less than 1000 lines. It looks like the virtualized lines get slow with this amount of long lines, but it actually has to do with the ANSI coloring (since they result in a ton of extra elements). If you set syntax_colors: [] to disable the coloring, you can even set width: :infinity and fit everything in a single line.

Thank you @jonatanklosko, that worked.
