375663610 MDU6SXNzdWUzNzU2NjM2MTA= 2528 display_width doesn't apply to dask-backed arrays 1197350 closed 0     3 2018-10-30T19:49:05Z 2020-09-30T06:17:17Z 2020-09-30T06:17:17Z MEMBER      

The representation of dask-backed arrays in xarray's __repr__ methods results in very long lines which often overflow the desired line width. Unfortunately, this can't be controlled or overridden with xr.set_options(display_width=...).

Code Sample, a copy-pastable example if possible

python import xarray as xr xr.set_options(display_width=20) ds = (xr.DataArray(range(100)) .chunk({'dim_0': 10}) .to_dataset(name='really_long_long_name')) ds

<xarray.Dataset> Dimensions: (dim_0: 100) Dimensions without coordinates: dim_0 Data variables: really_long_long_name (dim_0) int64 dask.array<shape=(100,), chunksize=(10,)>

Problem description

[this should explain why the current behavior is a problem and why the expected output is a better solution.]

Expected Output

We need to decide how to abbreviate dask arrays with something more concise. I'm not sure the best way to do this. Maybe really_long_long_name (dim_0) int64 dask chunks=(10,)
