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 Action author SDK, invocation shim, and Action 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}!")

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

The public author API is:

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