Question

this is a fairly general question about whether people should be using brackets on method calls that take parameters or not.
i.e.

def someFunc(def p) {
...
}

then calling:

someFunc "abc"

vs…

someFunc("abc")

Is this just a question of consistency, or is there specific use cases for each?

Answer 1

It’s primarily a question of consistency and readability, but note that Groovy won’t always let you get away with omitting parentheses. For one, you can’t omit parentheses in nested method calls:

def foo(n) { n }
println foo 1 // won't work

See the section entitled “Omitting parentheses” in the Style guide.
