# BlendDataLibraries(bpy_struct)

base class — `bpy_struct`

class `bpy.types.``BlendDataLibraries`(bpy_struct)

  Collection of libraries

  `is_updated`

    Type: | boolean, default False, (readonly)

  `tag`(value)

    tag

    Parameters: | value (boolean) – Value

  `load`(filepath, link=False, relative=False)

    Returns a context manager which exposes 2 library objects on entering. Each object has attributes matching bpy.data which are lists of strings to be linked.

    Parameters: | filepath (string) – The path to a blend file. link (bool) – When False reference to the original file is lost. relative (bool) – When True the path is stored relative to the open blend file.

        import bpy

        filepath = "//link_library.blend"

        # load a single scene we know the name of.
        with bpy.data.libraries.load(filepath) as (data_from, data_to):
            data_to.scenes = ["Scene"]

        # load all meshes
        with bpy.data.libraries.load(filepath) as (data_from, data_to):
            data_to.meshes = data_from.meshes

        # link all objects starting with 'A'
        with bpy.data.libraries.load(filepath, link=True) as (data_from, data_to):
            data_to.objects = [name for name in data_from.objects if name.startswith("A")]

        # append everything
        with bpy.data.libraries.load(filepath) as (data_from, data_to):
            for attr in dir(data_to):
                setattr(data_to, attr, getattr(data_from, attr))

        # the loaded objects can be accessed from 'data_to' outside of the context
        # since loading the data replaces the strings for the datablocks or None
        # if the datablock could not be loaded.
        with bpy.data.libraries.load(filepath) as (data_from, data_to):
            data_to.meshes = data_from.meshes
        # now operate directly on the loaded data
        for mesh in data_to.meshes:
            if mesh is not None:
                print(mesh.name)
