bd-utils 0.1.0

Databricks dbutils-compatible adapter for local and Databricks runtimes.

bd-utils

bd-utils provides a dbutils-like interface that works in both Databricks and local environments.

Goals

• Use native Databricks dbutils when running on Databricks.
• Use a predictable local implementation for tests and local scripts.
• Keep unsupported APIs explicit with actionable errors.

API compatibility target

bdutils mirrors the Databricks module layout:

• credentials, data, fs, jobs.taskValues, library, meta, notebook, preview, secrets, widgets, api

Locally, commonly used commands are implemented (widgets, secrets, fs, jobs.taskValues, notebook.exit); unsupported commands are present and raise NotImplementedError.

Quick start

import bdutils
value = bdutils.widgets.get("country")

Alternative (useful in tests when you need explicit config):

from bdutils import get_dbutils
dbutils = get_dbutils(force_adapter="local")
print(dbutils.fs.help("ls"))

Run tests

make test

This runs:

PYTHONPATH=src python -m pytest -q tests

Local widget lookup order

1. Values set with widgets.text(...) in-process
2. Environment variable DBX_WIDGET_<NAME_UPPER_SNAKE>

Local secret mapping

dbutils.secrets.get(scope, key) maps to environment variable:

DBX_SECRET__<SCOPE>__<KEY>

Notes

• dbfs:/... paths are mapped to ~/.bd-utils/dbfs/... by default.
• Unsupported methods raise NotImplementedError.
