PackageManager· method

PackageManager.load

load only the named packages into the running host

Python
load(names: Iterable[str], bus: Any = None) -> List[str]

Returns List[str] — sorted names of the newly registered classes

Parameters#

name type default description
names Iterable[str] — the package names to load (a subset of what's installed)
bus EventBus None optional desktop event bus; when given, package contributions are wired to it

Example#

Python
from lsdtools.advanced import PackageManager

pm = PackageManager()
new_classes = pm.load(["mim", "gis"])

Notes#

The project-scoped path: open a project and load exactly the packages it declares, rather than everything on disk (that's load_all). Idempotent — already-loaded and disabled packages are skipped. Returns the sorted list of Configurable class names (steps/entities) that newly appeared in the registry.
