The core set of Steps provided by Patched are designed to cover a wide range of common tasks in software development. However, there are always unique tasks that require custom steps. Patched allows you to create custom steps to automate these tasks.

​
Dashboard

Only available to Pro and Enterprise users
1

Navigate

In the patchflow builder’s Steps sidebar, click the Add Step icon next to the search box.
2

Describe

Describe the Step you wish to create in plain text, and provide the input and output schema.
3

Review

Review the generated code for the step and modify it as needed.
4

Validate

Validate the step by providing a sample input and clicking the Validate button.
5

Save

Once the step is validated, click the Save button. The step will now be available in the Steps sidebar for use in patchflows.

​
CLI

1

Fork

Fork the patchwork template repository to your machine.
2

Directory

Create a new folder for the step in the patchwork/steps directory with StepName.
3

Step File

Create a file named StepName.py in the newly created directory. Any additional files required for the step should be placed in the same folder.
4

Code

Implement the step logic in the StepName.py file. The step should inherit from the Step class provided by Patched. The StepName class is expected to have two methods:

  • init: The constructor of the class. It should accept an inputs dictionary as an argument. This dictionary contains the input data for the step. Checking of the presence and validity of the input data should be done here.
  • run: The main method of the class. This method should contain the logic of the step and return a dictionary with the results.
5

Initialize

Update patchwork/steps/init.py to include the new step in the list of available steps.

Below is an example of a custom step that takes two inputs and returns an output. For more details, view the Patchwork CLI documentation.

Example
Path: patchwork/steps/RunExample/RunExample.py
from patchwork.step import Step


class RunExample(Step):
    required_keys = ['input1', 'input2']

    def __init__(self, inputs):
        super().__init__(inputs)
        for key in self.required_keys:
            if key not in inputs:
                raise ValueError(f"Missing required input: {key}")

        self.input1 = inputs['input1']
        self.input2 = inputs['input2']

    def run(self) -> dict:
        return {
            'output1': "example output",
        }
Path: patchwork/steps/__init__.py
from .RunExample.RunExample import RunExample

__all__ = [
    ...
    'RunExample',
]
