"""
Combines multiple `EchoData` objects into a single `EchoData` object.
Parameters
----------
echodatas: List[EchoData]
The list of `EchoData` objects to be combined.
combine_attrs: { "override", "drop", "identical", "no_conflicts", "overwrite_conflicts" }
String indicating how to combine attrs of the `EchoData` objects being merged.
This parameter matches the identically named xarray parameter
(see https://xarray.pydata.org/en/latest/generated/xarray.combine_nested.html)
with the exception of the "overwrite_conflicts" value.
* "override": Default. skip comparing and copy attrs from the first `EchoData`
object to the result.
* "drop": empty attrs on returned `EchoData` object.
* "identical": all attrs must be the same on every object.
* "no_conflicts": attrs from all objects are combined,
any that have the same name must also have the same value.
* "overwrite_conflicts": attrs from all `EchoData` objects are combined,
attrs with conflicting keys will be overwritten by later `EchoData` objects.
Returns
-------
EchoData
An `EchoData` object with all of the data from the input `EchoData` objects combined.
Raises
------
ValueError
If `echodatas` contains `EchoData` objects with different or `None` `sonar_model` values
(i.e., all `EchoData` objects must have the same non-None `sonar_model` value).
ValueError
If EchoData objects have conflicting source file names.
Warns
-----
UserWarning
If the `sonar_model` of the input `EchoData` objects is `"EK60"` and any `EchoData` objects
have non-monotonically increasing `ping_time`, `time1` or `time2` values,
the corresponding values in the output `EchoData` object will be increased starting at the
timestamp where the reversal occurs such that all values in the output are monotonically
increasing. Additionally, the original `ping_time`, `time1` or `time2` values
will be stored in the `Provenance` group, although this behavior may change in future
versions.
Warnings
--------
Changes in parameters between `EchoData` objects are not currently checked;
however, they may raise an error in future versions.
Notes
-----
* `EchoData` objects are combined by combining their groups individually.
* Attributes from all groups before the combination will be stored in the provenance group,
although this behavior may change in future versions.
* The `source_file` and `converted_raw_path` attributes will be copied from the first
`EchoData` object in the given list, but this may change in future versions.
Examples
--------
>>> ed1 = echopype.open_converted("file1.nc")
>>> ed2 = echopype.open_converted("file2.zarr")
>>> combined = echopype.combine_echodata([ed1, ed2])
