Template: Registry-style digestion

Use this template when the library prefers a central registry rather than one file per argument.

Goal

• Define a module exposing ARGUMENT_DIGESTERS.

• ArgDigest discovers digesters via digestion_style="registry".

Required structure

my_lib/
  _argdigest.py
  _private/
    digestion/
      registry.py

Library config (my_lib/_argdigest.py)

DIGESTION_SOURCE = "my_lib._private.digestion.registry"
DIGESTION_STYLE = "registry"
STRICTNESS = "warn"
SKIP_PARAM = "skip_digestion"

Programmatic config alternative (my_lib/__init__.py)

import argdigest.config

argdigest.config.set_defaults(
    digestion_source="my_lib._private.digestion.registry",
    digestion_style="registry"
)

Registry module (registry.py)

def digest_a(a, caller=None):
    return int(a)


def digest_b(b, a=None, caller=None):
    return int(b) + int(a)


ARGUMENT_DIGESTERS = {
    "a": digest_a,
    "b": digest_b,
}

Usage in public API

from argdigest import arg_digest

@arg_digest(config="my_lib._argdigest")
def analyze(a, b, skip_digestion=False):
    ...
