My noodlings so far trying to reimplement the underlying tree structure.
All together this will:
Store unnamed child nodes in a dict rather than named children in a tuple, closing Should .children be a dictionary instead of a tuple? #3,
Replace the
TreeNodeclass with entirely our own code, so removing the anytree dependencyand closing Remove dependency on anytree #7,
Use a
TreeNodeclass which can handle relative paths (e.g. '../var'), closing Re-implement path-like access using pathlib? #12.Make it easier to enable mypy because we won't have missing typing stubs for a key component anymore.

EDIT: This PR introduces a lot of breaking changes (see the
whats-newfile)Changes the return type of
.childrento a FrozenDict (previously Tuple),Removes tag-like access (i.e. using
dt[('folder', 'var')]as an alternative todt['folder/var'], because I decided that was not helpful.Changes the syntax for accessing nodes to be more file-like.
Changes the
__init__signature forDataTree.Removes the option to delete all data in a node by assigning
Noneto the node (in favour of deleting data using the xarray API), or to create a new empty node in the same way (in favour of assigning an empty DataTree object instead).
