Silence development warning output

[bensheldon]

I think this output should all be silenced because it's not actionable afaik.

I'm not sure about the best way to do it, but I did something like this recently in Spectator Sport:

# gem 'warning' in gemfile too

# spec/spec_helper.rb
require "warning"
Warning.ignore([ :not_reached, :unused_var ], /.*lib\/mail\/parser.*/)

Yes, the mail gems are annoying. Don't know what I did but didn't get them when adding $VERBOSE = true but I do see it myself now too. I added this in rubocop: https://github.com/rubocop/rubocop/blob/master/spec/support/strict_warnings.rb

It's heavily inspired from the module of the same name in rails. Can me stripped down for GoodJob needs. That warning gem works too I guess, though I haven't used it. Blanket ignoring :not_reached / :unused_var doesn't seem good since these could come from GoodJob itself (though highly unlikely with a linter). Generally I like to see these anyways from other gems to help them out if I encounter them.

stringio/psych warnings could be from homebrew/rbenv? Shopify/bootsnap#112 (comment) It's an older comment so not sure if still relevant.
