Pre-release

This release is a pre-release and may not be stable for production use.

Pyplines Python Library

The Pyplines Python library provides the Function author SDK, invocation shim, and Function Package tooling used by Pyplines runtime and development images.

from pyplines import Context, Input, Output


class GreetingInput(Input):
    name: str


class GreetingOutput(Output):
    message: str


def handler(i: GreetingInput, ctx: Context) -> GreetingOutput:
    ctx.log.info("Building greeting", name=i.name)
    return GreetingOutput(message=f"Hello, {i.name}!")

Function projects use pyplines.pkg.function.build_backend and declare exactly one handler under [tool.pyplines.function]. The Function development container calls python -m pyplines.pkg.function to check projects and build hermetic Function Package archives.

The public author API is:

from pyplines import ArtifactRef, Context, Error, Input, Output
