Release a new version for Ruby < 2.1 compatability

[schoblaska]

Trying to load this gem in Ruby 2.0, I get the following error:

shared/bundle/ruby/2.0.0/gems/sidekiq-unique-jobs-4.0.9/lib/sidekiq_unique_jobs/util.rb:12: syntax error, unexpected ','
    def del_by(pattern = SCAN_PATTERN, count:, dry_run: true)

The required keyword syntax being used for the "count" parameter wasn't introduced until Ruby 2.1. I saw that this was fixed in master with this commit (045ca89), but there hasn't been a new version of the gem since that change. Doing a version bump should fix this problem for me and others.

Thanks for the great gem!

Ah sorry about that! I'll do it first thing tomorrow!

[mhenrixon]

Sorry about the delay, had some unfinished changes locally. Could you check and see if the recent release fixes your issue?

Hmm, now I'm getting a new error: uninitialized constant SidekiqUniqueJobs::Scripts::SingleForwardable

$ rvm use 2.0

You want version 4.0.10 I think. SingleForwardable has been available
since forever.

[mhenrixon]

Not sure if you are aware but ruby 2.0 won't be maintained after end of February. Time to upgrade.

[schoblaska]

Ah, "forwardable" needs to be explicitly required somewhere.

$ rvm use 2.2
$ gem list | grep sidekiq
sidekiq (4.0.1)
sidekiq-unique-jobs (4.0.10)

$ ruby -e "require 'rubygems'; require 'sidekiq-unique-jobs'"
/Users/joey/.rvm/gems/ruby-2.2.2/gems/sidekiq-unique-jobs-4.0.10/lib/sidekiq_unique_jobs/scripts.rb:14:in
  `<module:Scripts>': uninitialized constant SidekiqUniqueJobs::Scripts::SingleForwardable (NameError)

$ ruby -e "require 'rubygems'; require 'forwardable'; require 'sidekiq-unique-jobs'"
(no error)

[mhenrixon]

Fixed in d4c24b1 v4.0.11

[schoblaska]

Awesome. Thanks a lot!
