b3rnie/crontab

This system is a lightweight Erlang library for managing periodic background jobs in long-running applications. It provides a cron-like API to schedule and cancel tasks based on time specifications, utilizing a dedicated gen\_server for execution. The codebase includes core scheduling logic, time parsing utilities, and test support infrastructure.

This change introduces the Crontab library, a simple scheduling application for Erlang designed for long-running applications that need to run periodic jobs. It provides an API to add and remove scheduled tasks using cron-like specifications (supporting minutes, hours, days, months, and years, including named days of the week). The release includes the core application code, a Makefile for building and testing via rebar3, and comprehensive documentation in README.md detailing usage examples and API signatures. The project is licensed under the MIT License.

The application has been renamed from 'scheduler' to 'crontab', replacing the old \scheduler\ module with a new \crontab\ module that exposes \add/3\, \add/4\, \remove/1\, and \remove/2\ functions. The underlying implementation has been refactored to use a dedicated \crontab\_server\ gen\_server and a \crontab\_time\ module for parsing and calculating cron schedules, while the old \scheduler\ source files and application resource have been removed.

src · high confidence

Added a new test support module (crontab\_test.erl) that provides helper functions for running tests, including utilities to start and stop the crontab application and wait for it to be ready.
