Full Changelog: v0.7.0...v0.8.0

v0.7.0

What's Changed

• Default chunks fix by @d-v-b in #28

That PR contains:

docs:

• a bunch of prose improvements, some new sections, and some broken links removed

ArraySpec.from_array

• When chunks is "auto", use guess_chunks from zarr-python instead of defaulting to a single chunk. A single chunk is completely wrong for large arrays.
• expand the function signature of from_array to explicitly list the relevant parameters of the ArraySpec constructor (banishing **kwargs code smell),
• make each parameter default to "auto", which dispatches to functions that attempt to infer an attribute value from the input data. The default behavior now is that an array with an attrs attribute will have the attrs propagate to the resulting ArraySpec.attributes, and similarly for chunks (in the case of this specific attribute, we also check for chunksize to accomodate dask arrays). If this ends up being terrible I will revert it.

to_zarr

• overwrite is an explicit keyword-only argument

support for python 3.9

• import TypeAlias from typing_extensions
• add some little pydantic dependency that enables the modern union | operator
• add python 3.9 to the test matrix in ci

Full Changelog: v0.6.0...v0.7.0

v0.6.0

What's Changed

• add to_flat, from_flat by @d-v-b in #25.
  These methods allow creating GroupSpec instances to / from a flat "dict of strings" representation of a hierarchy.

• add like method for GroupSpec and ArraySpec by @d-v-b in #25
  This method allows for parametrically comparing GroupSpec and ArraySpec instances to other Group/ArraySpec, or to zarr.Group or zarr.Array.

• add depth kwarg to GroupSpec.from_zarr that limits the depth of tree traversal. by @d-v-b in #25

• [breaking] GroupSpec.members is nullable, to accommodate the flat hierarchy representation, and to accommodate limiting recursion depth in GroupSpec.from_zarr by @d-v-b in #25.

• fix repo name in docs by @d-v-b in #26
