Hi folks, i got a question about formatting. I can see in intelij, when i reformat two times it removes custom break likes and when in functions i have like 3 or 2 arguments it reformats it in a signle line for example: Before double reformatting
private suspend fun authRequest(
    codeVerifierDeferred: Deferred<CodeVerifier>,
    urlDeferred: Deferred<String>,
    code: String
) {
After
private suspend fun authRequest(
    codeVerifierDeferred: Deferred<CodeVerifier>, urlDeferred: Deferred<String>, code: String
) {
What is the best approach in your opinion? is this per kotlin style default? I also checked kotlin.coroutines code style and they also have custom break lines in functions, so my guess is that it is ok to have custom break lines in functions but how do i disable intelij to not remove custom break lines in functions? Thanks in advance ! 🙂

This doesn't happen with me. It leaves the lines as they are, and Ctrl+Alt+L says the file is already properly formatted. What style are you using? I've selected Settings > Editor > Code Style > Kotlin > Set from... Kotlin Style Guide.

im using per project style, the one in coroutines is the offical code style so it seems weird that it lets me remove custom break lines. In my own project i generated an .editorsconfig and set the settings there (but at the end the .editorsconfig is generated from intelij with kotlin code style) here is my editorconfig

Keep in mind that when i double press reformat the file it removes custom break lines, meaning two times CTRL + ALT + L

I believe that it's precisely a harder-to-activate feature because custom line breaks are absolutely fine, but sometimes you might wish to strip them all away for simplicity

I hadn't noticed that before, as I had never clicked Ctrl+Alt+L twice, but yes it does that with me too. It first asks "You do want to remove custom line breaks?"
