since-when

since-when is a way to manage repeated cron-like jobs in ruby. Rather than trying to recreate or replace proven scheduling tools, it works with them.

Installation

Add this line to your application's Gemfile:

gem 'since-when', github: 'modcloth-labs/since-when'

then execute:

$ bundle

Usage

  SinceWhen::MissedRunner.new('/path/to/metafile').run(:day) do |time|
    # run your job with each yielded time
  end

• since-when will use the metafile to track when your job ran last, and calculate the in-between times it should have run since the last run.

• If your job completes successfuly, since-when will update the metafile based on the last successful run time.

• If your job raise an exception, since-when will handle it by only updating the metafile to the last successful runtime (or not at all if all job executions failed).
