Using ActiveSupport StringInquirer for pretty String equality

ActiveSupport is pretty awesome. It has really awesome stuff hidden in it.StringInquirer is one of them.

It lets you test String equality in a much more pretty way. Rails also uses StringInquirer for it’s environment check.

You may recognize this

Rails.env.production?

Instead of doing

Rails.env == 'production'

So how can we use StringInquirer for ourselves.

Let’s pretend that we have a String called status.

status = ActiveSupport::StringInquirer.new 'is_used'
status.is_used? # true
status.is_new? # false

Happy hacking <3
