# prophecy-libs — Helper library for prophecy generated code

License: copyleft · Maintenance: active · Downloads: 121.8K/mo

## What it is and what it does

prophecy-libs is a runtime support library for the Prophecy data orchestration platform. It bundles helper functions and utilities that Prophecy's code generation engine embeds into generated Python workflows. The library wraps six external dependencies—pyhocon for configuration, requests for HTTP, hvac for Vault secrets access, zstandard for compression, msgspec for serialization, and websocket-client for real-time communication—into a single importable package.

The library is designed to be used as part of Prophecy-generated code rather than as a standalone tool. It handles common operational concerns like reading configuration files, making authenticated HTTP calls, retrieving secrets from HashiCorp Vault, and managing data compression. Because it carries a GPL-3.0 copyleft license, any project that imports it must comply with copyleft obligations, making it unsuitable for proprietary or closed-source applications without explicit license compatibility.

Use it for:

- Running Prophecy-generated data pipelines that require configuration parsing and HTTP communication
- Accessing secrets stored in HashiCorp Vault from within Prophecy workflows
- Compressing or decompressing data in Prophecy-orchestrated ETL jobs using zstandard
- Serializing and deserializing structured data in generated code via msgspec
- Establishing WebSocket connections for real-time data streaming in Prophecy workflows

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides runtime support and helper utilities for Python code generated by the Prophecy data orchestration platform, including configuration parsing, HTTP requests, secrets management, and compression.

Yes, if you are running Prophecy-generated code and your project is GPL-3.0 compatible. No, if your project is proprietary or closed-source, or if you need a permissive license. The package itself is actively maintained and has low install friction, but the copyleft license is a hard blocker for many use cases.

## Install

pip install prophecy-libs
uv add prophecy-libs
poetry add prophecy-libs

## Installing prophecy-libs

Before you install: Low install friction with a pure Python wheel and six common runtime dependencies. Active maintenance status with a recent release (122 days ago).

License in practice: GPL-3.0 copyleft license means any code that imports and uses this library must also be released under GPL-3.0 or a compatible copyleft license—a significant constraint for proprietary or closed-source projects.

Quickstart:

pip install prophecy-libs

from pyhocon import ConfigFactory
import requests

# Use within Prophecy-generated code context

GPL-3.0 copyleft license applies to any code that imports this library; verify compatibility with your project's license before use.

Verify before relying:

- Whether this package is intended for direct use or only as a transitive dependency of Prophecy-generated code
- What Python versions are actually supported (requires_python is unspecified)
- Whether the six runtime dependencies are all required or conditionally loaded
