Source.of

builds a source of any registered custom kind

Python
of(kind: str, **config) -> Source

Returns Source — a source of the given registered kind

Parameters#

name type default description
kind str — the registered kind name, e.g. "largecsv"
**config Any — config fields for that kind, passed by keyword

Example#

Python
from lsdtools import Source

Source.of("largecsv", path="huge.csv", threshold_mb=200)

Notes#

kind must be a source kind registered with @tool.source; the keyword config values must match the fields of that kind's config UI tree — they are handed to the kind's reader as a dict. Use file or sql for the two built-in kinds.
