Introduction

Yenta is YEt ‘Nother TAskrunner; it executes a pipeline, defined by a series of tasks and dependencies among them. The goal of Yenta is to provide a reasonable feature set while maintaining simplicity and usability. Yenta tasks are simply functions decorated with the @task decorator and complying with a specific format for their arguments.

Yenta is inspired in part by the functional state management pattern used in projects like Redux. Although I would hesitate to call Yenta “functional” in the strict sense, it does use a caching logic according to which identical inputs are assumed to produce identical outputs under default conditions. This means that Yenta will automatically reuse the cached output of a task if nothing about the inputs has changed.

The name “Yenta” is an old Yiddish name; in the American Yiddish theater of the 30s, a character named Yenta was depicted as a busy-body, so the name became a byword for someone who won’t mind their own business.
