"""
Returns an msvc version and a toolset version given a version
specification.
This is an EXPERIMENTAL proxy for using a toolset version to perform
msvc instance selection. This function will be removed when
toolset version is taken into account during msvc instance selection.
Search for an installed Visual Studio instance that supports the
specified version.
When the specified version contains a component suffix (e.g., Exp),
the msvc version is returned and the toolset version is None. No
search if performed.
When the specified version does not contain a component suffix, the
version is treated as a toolset version specification. A search is
performed for the first msvc instance that contains the toolset
version.
Only Visual Studio 2017 and later support toolset arguments. For
Visual Studio 2015 and earlier, the msvc version is returned and
the toolset version is None.
Args:
version: str
The version specification may be an msvc version or a toolset
version.
prefer_newest: bool
True: prefer newer Visual Studio instances.
False: prefer the "native" Visual Studio instance first. If
the native Visual Studio instance is not detected, prefer
newer Visual Studio instances.
Returns:
tuple: A tuple containing the msvc version and the msvc toolset version.
The msvc toolset version may be None.
Raises:
MSVCToolsetVersionNotFound: when the specified version is not found.
MSVCArgumentError: when argument validation fails.
