Hi! Is there an existing rule that would report if some also is unnecessary, for example

foo.also { bar() } // doesn't use "it"

[Landry Norris]

I often use this with expressions. Sometimes I just need

fun foo() = Bar().also { baz() }

With this rule, it'd make me use a full function body.

[Landry Norris]

Typically baz would use the new Bar in some way, needing 'it', but not always.

Ah, right, thats a nice use case.

I've just found

fun foo() {
  val x = 3
  bar().also { baz() }
}

in our code and thought it makes no sense.

I guess it was using it at some point, which got lost after some edit.

I may try to write a rule for this which would exclude your case.

[Landry Norris]

A rule like this with an option to ignore expressions makes sense. Expressions are the only case I can think of where this matters.

Hi @Landry Norris / @dimsuz can you create a new issue in the repo(if not already created)?

[dimsuz]

I thought I'd try to implement + apply this rule in the local ruleset to test it out...

[Atul Gupta]

That's more better. Than also push it to detekt 😀
