Using ktlint - f remove wrong semi colon

[Mathieu-Heuzey]

Hello guys, i had an issue using the command "ktlint -f".

I have a kotlin class declaring a companion object like this "companion object;", I needed it to add more properties as extension function outside of it .

but when i use the command "ktlint -f" the semi colon is removed, and the my project does not compile because the companion object is not found anymore.

Hi @Mathieu-Heuzey. Any chance you can provide a complete example? Thanks.

Here is my first class with my companion object

class FirstClass(private val param: String) {

    // Needed to add more properties as extension function outside of it
    companion object;

private var toto : Boolean = false

}

Here is my extension function

fun FirstClass.Companion.create(c: Context) {
            return;
}

Then, when i run "ktlint -F", my semicolon after my companion object will be removed, and without it it does not compile. Is that clear for you or you need more than an example ?

Thank you. That's all I need.

I'll have a fix shortly. As temporary workaround please use:

	companion object; // ktlint-disable no-semi

---

(for future reference (looks like kotlin compiler bug)):

$ cat FirstClass.kt
class FirstClass(private val param: String) {

    // Needed to add more properties as extension function outside of it
    companion object;

    private var toto: Boolean = false
}

fun FirstClass.Companion.create(c: Context) {
    return
}

class Context

$ ktlint FirstClass.kt 
/tmp/FirstClass.kt:4:21: Unnecessary semicolon

$ kotlinc FirstClass.kt 

$ ktlint -F FirstClass.kt 

$ kotlinc FirstClass.kt 
FirstClass.kt:9:16: error: unresolved reference: Companion
fun FirstClass.Companion.create(c: Context) {
               ^
