A minimal library for scheduling jobs for later execution.

Installation

Add this line to your application's Gemfile:

gem 'schdlr', git: 'https://github.com/devsfutter/schdlr.git'

And then execute:

$ bundle

Usage

class Job < Schdlr::Job
    attr_accessor :id
    def perform
        puts "#{Time.now}: Job2 doing something with id: ##{id}"
        return true
    end
end

class JobThatFail < Schdlr::Job
    attr_accessor :id
    def perform
        puts "#{Time.now}: JobThatFail doing something with id: ##{id}"
        fail!('missing argument :id') if id.nil?
    end
end

@queue = Schdlr::Queue::Sqlite.new
@schhlr = Schdlr.new(@queue)

job1 = Job.new(id: '12344')
job2 = JobThatFail.new

@schhlr.now(job1) #=> schhlr.at(Time.now, job1)
at_time = Time.new(2019,2,2)
@schhlr.at(at_time, job2)
#Start processing queue
@schhlr.start!
# => 2019-01-27 13:40:21 +0100: Job2 doing something with id: #12344
# (time passes by)
# => 2019-02-02 00:00:00 +0100: JobThatFail doing something with id: #
#Stop processing queue
@schhlr.stop!

TODO

• [ ] Failed tasks stays in the queue, they should have a status to avoid retrying failed tasks.
• [ ] Improve test suite.
