This morning, I tooted about Ruby’s
unless use case.
It says, “Do not put multiple conditions after
unless in Ruby.”
Some responded to this toot in the local timeline, and I got several good feedbacks.
# Using `unless` with multiple conditions. # Confusing... publish! unless state == "published" && published_at.present? # Using `if`. # Better publish! if state != "published" || published_at.blank? # Define a new private method for the purpose. # Good publish! if ready_to_publish? ## Other examples ## # omg... x unless x > 1 && x < 10 # ... x if x < 1 || x > 10 # better? # i'm ok using `unless` toward single condition. x unless x.between?(1, 10) x unless (1..10).cover?(x)
Thought rubocop has a rule like
AvoidMultipleConditionsAfterUnless, it doesn’t.
I hate the gem much more.
I don’t understand the pros with using
unless for multiple conditions and I asked it to the code-reviewee, but I don’t receive any reply.
I’ll add things on this post after I could get any response from him.
