ldr-environment 0.1.0

Methods to interact with the environment.

Environment utilities

This library is for the most part a wrapper on the os stdlib module.

ldr.environment.get

Loads an environment variable, a default, or None if no default is provided and the var is unset.

ldr.environment.require

Loads an environment, a default, or raises a ldr.environment.MissingVarError if no default is provided and the var is unset.

ldr.environment.google

This module contains pydantic models that will load Google Cloud Run container contract variables into a model.

from ldr.environment.google import CloudRunJob

# When in a Cloud Run Job environment.
job_vars = CloudRunJob()
assert job_vars.job == "my-job-name"
assert job_vars.task_index == 1

# Or locally

job_vars = CloudRunJob()
assert job_vars.job is None

ldr.environment.config

Load configuration from the environment.

ldr.environment.config.use_pretty_exceptions

Check whether to use pretty exceptions.

Reads from the PRETTY_EXCEPTIONS env var. Valid values are:

• y | yes | enable | true: Enable pretty exceptions
• auto: Check for Cloud Run container env vars and disable if any are present.
• Any other value: Disable pretty exceptions

Defaults to auto if unset.
