Kotest uses following format for defining specs (tests):

class MyTests : StringSpec({
   "length should return size of string" {
      "hello".length shouldBe 5
   }
})

Kotest (standard ruleset) formats it as following:

class MyTests : StringSpec(
  {
    "length should return size of string" {
      "hello".length shouldBe 5
    }
  },
)

How do I prevent it from add a newline for the spec body lambda here? I see there was already this ticket for this from 4 years ago but curious if there's a solution here? What's the rule controlling this behavior?

I think it's multiline-expression-wrapping that causes the issue. You can disable it by adding this to your .editorconfig

ktlint_standard_string-template-indent = disabled
ktlint_standard_multiline-expression-wrapping = disabled

[Kirill Zhukov]

Already have both disabled

I think it's the trailing comma at the call site actually

[Kirill Zhukov]

ij_kotlin_allow_trailing_comma_on_call_site = false disabling this fixes it

[Emil Kantis]

ah..

[Kirill Zhukov]

Is there a way to make trailing commas at callsite optional? That is, they don't get added automatically but they don't get removed either.

[Kirill Zhukov]

It's nice to have in most cases, but I guess I wish it didn't remove the comms even if the rule is disabled

[Paul Dingemans]

No this can not be configured. Either you choose to use them always, or never. Ktlint is more restrictive in this then default formatter of Intellij IDEA.

Unfortunate! Thanks
