QUESTION

What does the &quot;-&quot; mean in front of a ruby symbol?

Asked 2022-Mar-21 at 11:50

When I had a look into the ActiveRecord source today, I stumbled upon these lines

name = -name.to_s
ar.aggregate_reflections = ar.aggregate_reflections.merge(-name.to_s => reflection)

ANSWER

Answered 2022-Mar-21 at 11:05

That's String#-@:

Returns a frozen, possibly pre-existing copy of the string.

Example:

a = "foo"
b = "foo"

a.object_id #=> 6980
b.object_id #=> 7000

vs:

a = -"foo"
b = -"foo"

a.object_id #=> 6980
b.object_id #=> 6980
