datamorph-python 1.22.1

Python bindings for the DataMorph transformation engine

datamorph-python

datamorph-python exposes the DataMorph transformation engine as a normal Python package.

Install it with:

pip install datamorph-python

Then import it with:

from datamorph import evaluate, read, write

Quick Start

from datamorph import evaluate

script = """
output application/json
---
{
  id: payload.id,
  requestId: headers.requestId,
  stage: attributes.stage,
  env: vars.env
}
"""

result = evaluate(
    script,
    payload={"id": 42},
    headers={"requestId": "req-001"},
    attributes={"stage": "test"},
    variables={"env": "dev"},
)

assert result == {
    "id": 42,
    "requestId": "req-001",
    "stage": "test",
    "env": "dev",
}

API

• evaluate(script, payload=None, headers=None, attributes=None, variables=None, payload_mime=None)
• transform(...) as an alias for evaluate(...)
• eval_expression(expression)
• read(input_text, mime_type)
• write(data, mime_type)
• validate(script)
• version()

Notes

• Package name on PyPI: datamorph-python
• Import name in Python: datamorph
• Wheels built from this folder contain the Rust engine, so users do not need a separate DataMorph installation.
