pathlib

Nu surface for Python's `pathlib` module - pure path operations only.

Module nustd.pathlib.

Nu surface for Python's pathlib module - pure path operations only.

Mirrors pathlib 1-1: Path is the class (a Form), backed by PurePath so only the lexical operations that never touch the filesystem are modeled. pathlib has no module-level functions, so there are just two layers: forms (the class) and interactions (the constructor and method atoms; property reads use core GetAttr, comparison uses the core atoms). Import it like the stdlib:

from nustd.pathlib import Path
import nustd.pathlib as pathlib    # pathlib.Path.of("a", "b"), ...

Path

pathlib path as a Form - the pure (no filesystem I/O) surface.

Path()

Path nustd.pathlib.Path. Kind ScalarQuery, sort scalar_query, cardinality scalar.

Named Path to mirror from pathlib import Path; backed by PurePath, so only the lexical operations are modeled. Build one with Path.of(...); read its components as properties; transform it with the method calls or the / operator.
