v1.2.0 (2022-06-09)

From this release, special type hints (Attr, Coord, Data, Name) can be used within union types.
This would be useful if you want to customize values after dataclass object creation (__post_init__).
The following example automatically sets ranged values to x and y coordinates if they are not specified.

import numpy as np
from dataclasses import dataclass
from typing import Literal, Optional
from xarray_dataclasses import AsDataArray, Coord, Data


X = Literal["x"]
Y = Literal["y"]


@dataclass
class Image(AsDataArray):
    """2D image as DataArray."""

    data: Data[tuple[X, Y], float]
    x: Optional[Coord[X, int]] = None
    y: Optional[Coord[Y, int]] = None

    def __post_init__(self) -> None:
        """Set ranged values to x and y."""
        shape = np.shape(self.data)

        if self.x is None:
            self.x = np.arange(shape[0])

        if self.y is None:
            self.y = np.arange(shape[1])
