Feature request: xr.set_option('display.max_data_vars', N)

[raybellwaves]

idea discussed here: #4991

Copying here

the data_vars method provides a convenient ways to see the varaibles and the formatting (https://github.com/pydata/xarray/blob/master/xarray/core/dataset.py#L484) is nice. However, there are times I would look to see the full variables names not just a subset (12 is the default).

Ideally there would be a setting to toggle to specify the length of the formatter akin to https://pandas.pydata.org/pandas-docs/stable/user_guide/options.html#overview

xr.set_option('display.max_data_vars', N)

Problem is that xarray is very unresponsive when you're printing many variables, see #4736. But this should do what you want I believe xr.set_option("display_max_rows", N).

Thanks @Illviljan. I missed that issue. Is the syntax above off slightly? Is it in the docs as well?

[Illviljan]

I might have missed adding it in docs. It's here though: https://github.com/pydata/xarray/blob/master/xarray/core/options.py

Ah, it should be xr.set_options(display_max_rows=20)

Thanks. Works great. Closing.
