Do you leave parentheses in or out in Ruby? [closed]

Answer 1

I use parens as comments to help the future me... who is likely to have fewer brain cells than the current me :-)

Nothing worse than looking at some code you wrote 2 years ago and misunderstanding it, so that you break something while modifying it.

If parens will save the future me a few minutes (or hours) in the future, I'll put in as many as needed to make the statement crystal clear.

Answer 2

I tend to leave them out when doing assertions such as assert_equal. Maybe it's to make it domain specific language-like.

Answer 3

I try to leave them out, if at all possible. I think it makes code easier to read (generally speaking).

Answer 4

If you've been programming for a long time, you'll probably have an "itch" to add parentheses, and in many cases there are good reasons for this.

The code is easier on the eyes though in my opinion, and I haven't run into a problem yet--if you're going to need parentheses, you'll know it beforehand before you have to run into the debugging script.

Answer 5

I leave them out when I'm doing DSL-ish stuff, like t.column or has_many in rails. The rest of the time, it generally comes down to clarity, and it's probably an even split.

Answer 6

Whichever is more readable usually.

But I always use parentheses when I'm nesting function calls inside other ones' parameters
