Ktlint-cli --code-style=intellij_idea is not respected in ktlint 1.0.0

[voegelas]

Expected Behavior

In the following example, ktlint should not complain about "multiline-expression-wrapping" if the code style is set to "intellij_idea".

val chars = "foo".map { c ->
    c
}

Observed Behavior

ktlint 1.0.0 outputs a "multiline-expression-wrapping" warning and inserts a newline and an extra indentation level if the code is formatted. Intellij IDEA doesn't do that and puts the lambda expression back on the first line if the code is formatted twice. ktlint 0.50.0 works as expected.

val chars =
    "foo".map { c ->
        c
    }

Steps to Reproduce

Run ktlint --code-style=intellij_idea example.kts on the first example.

Your Environment

• Version of ktlint used: 1.0.0
• Operating System and version: Fedora 38 with OpenJDK 17 and Kotlin 1.9.0

Property --code-style=intellij_idea is indeed not passed correctly to ktlint rule engine. Also in previous versions this was not done correctly but in those releases the default codestyle was intellij_idea.

When you specify the code style in the .editorconfig file, it is respected though. This is also the preferred way to specify the code style as it will then be used by everyone working on the same project (provided that the .editorconfig is committed to the repository).

root = true

[*.{kt,kts}]
ktlint_code_style = intellij_idea

I think that it's useful to be able to pass the code style on the command line. I've started to use Kotlin for scripting too. Adding an .editorconfig file to each and every script and repository is cumbersome. I've got the following settings in my Vim configuration:

let b:ale_fixers = ['ktlint']
let b:ale_kotlin_ktlint_options = join([
  \ '--log-level=none',
  \ '--code-style=intellij_idea',
  \ ])

I've built a self-executable ktlint that defaults to "intellij_idea". I'm fine with this solution. No need to keep --code-style.
