nustd – the Nu standard library
Batteries for Nu: the fabrics that reach the outside world, and Python's stdlib as Nu.
About • Install • Reference • nu
ℹ️ About
nucore is the kernel: the language, the engine, the core atoms, flows,
spans, forms, the tree rewrites, nu.prog, nu.inspect, and nu.mem, the
in-memory fabric over plain dicts. No other fabric lives in it.
nustd is everything that talks to the outside world. One import, then
dot-access: import nustd, then nustd.kv, nustd.ui, nustd.uuid.

The standard library sits at the same level, one module per Python stdlib
module it mirrors: nustd.uuid, nustd.datetime, nustd.decimal,
nustd.math, nustd.pathlib, nustd.logging, nustd.fin and the rest. No
extra needed, they are pure Nu.
A library whose values can sit in a slot carries the leaves for them, one
submodule per fabric: nustd.decimal.mem.DecimalRef for nu.mem,
nustd.decimal.kv.DecimalRef for nustd.kv.
Install
pip install nustd[all] # everything
pip install nustd[kv,ui] # just what you need
nucore comes along as a dependency.
Released in lockstep with nucore. Docs at
nustack.dev.
