pipen-deprecated

Marking pipen processes as deprecated.

Installation

pip install -U pipen-deprecated

Enable/Disable

The plugin is enabled by default after installation. To disable it, either uninstall it or:

from pipen import Proc, Pipen

# process definition

class MyPipeline(Pipen):
    plugins = ["-deprecated"]

Usage

To mark a process as deprecated, use the @mark(deprecated=...) decorator.

from pipen import Proc
from pipen.utils import mark

@mark(deprecated=True)
class ProcDeprecatedTrue(Proc):
    ...


@mark(deprecated="This process is deprecated.")
class ProcDeprecatedMessage(Proc):
    ...

When a deprecated process is run, a warning message will be logged.

If the process is marked with deprecated=True, the message will be:

[ProcDeprecatedTrue] is deprecated and will be removed in a future release.

If a custom message is provided, it will be used instead:

[ProcDeprecatedMessage] This process is deprecated.

You can use proc in the message as a placeholder for the process class. For example:

@mark(deprecated='"{proc.name}" is deprecated.')
class ProcDeprecatedMessage(Proc):
    ...

This will log:

"ProcDeprecatedMessage" is deprecated.
