what is the target API binding for BUILD file objects?

I’m not quite sure what you mean. Is this the

target_types

register.py

entry point question?

it appears to be:

@classmethod
    def alias_groups(cls):
        return BuildFileAliases(
            objects={
                "pants": lambda x: x,
                "artifact": Artifact,
                "scala_artifact": ScalaArtifact,
                "public": Repository(
                    name="public", url="<http://maven.example.com>", push_db_basedir="/tmp"
                ),
            },
        )

Ohh, yes, it is still

objects

. We punted on that because Daniel’s prelude macros feature was in flight.

ok, i haven't been following that

Unless the repo never uses V1, they still need to have V1 bindings for the V2 target API, unfortunately. Meaning that they need to keep

build_file_aliases

around until then. So, we punted on what the future of

objects

is since

build_file_aliases

will be around a bit longer See https://github.com/pantsbuild/pants/pull/9618
