Library for creating evergreen configurations

shrub.py

A python based Evergreen project config generation library

Overview

Based on shrub, shrub.py is a library for programatically building Evergreen project configurations described here.

Example

The following snippet will create a set of parallel tasks reported under a single display task. It would generate json used by generate.tasks:

from shrub.v2 import ShrubProject, Task, BuildVariant

n_tasks = 10
def define_task(index):
    name = f"task_name_{index}"

    return Task(
        name,
        [
            FunctionCall("do setup"),
            FunctionCall(
                "run test generator",
                {"parameter_1": "value 1", "parameter_2": "value 2"}
            ),
            FunctionCall("run tests")
        ],
    ).dependency("compile")

tasks = {define_task(i) for i in range(n_tasks)}
variant = BuildVariant("linux-64").display_task("test_suite", tasks)
project = ShrubProject({variant})

project.json()
