Formatting not consistent with idea / AS

[PaulWoitaschek]

The following file is formatted correctly according to ktlint:

import java.time.LocalDate
import java.time.temporal.ChronoUnit

fun test() {
    val lastActive = LocalDate.now()
    if (lastActive != null && ChronoUnit.DAYS.between(
        lastActive,
        LocalDate.now()
    ) > 30
    ) {
        println("hello")
    }
}

I applied ktlints configuration to idea using:
ktlint applyToIDEA

When now formatting the code using idea, it generates a different intendation:

diff --git a/src/main/kotlin/test.kt b/src/main/kotlin/test.kt
index 5c49ec7..fcb3329 100644
--- a/src/main/kotlin/test.kt

     ) {
         println("hello")
     }

I created a sample project here: https://github.com/PaulWoitaschek/KtLintFormattingBug
Versions:

• ktlint 0.37.1
• Android Studio 4.0 / idea 2020.2.1

Yes, continuation indent size is set to 8:

ktlint/ktlint/src/main/resources/project-config/.idea/codeStyles/Project.xml

Line 15 in e528091

<option name="CONTINUATION_INDENT_SIZE" value="8" />

Will update it to 4

I don't get it. Isn't that for xml?

No, it is for kotlin files. applyToIDEA just writes two xml files (Project.xml and ktlint.xml) into ./.idea/codeStyles/ folder. This xml files are pretty simple and may not reflect what actual rules expect.

See #701 for possible solution how to improve this situation.

The line you posted:

    <codeStyleSettings language="XML">
      <indentOptions>
        <option name="CONTINUATION_INDENT_SIZE" value="8" />
      </indentOptions>
    </codeStyleSettings>

is definately for xml or am I missing something?

[Tapchicoma]

Yeah, this one for xml, few lines below the same for kotlin:

ktlint/ktlint/src/main/resources/project-config/.idea/codeStyles/Project.xml

Line 28 in e528091

<option name="CONTINUATION_INDENT_SIZE" value="8" />
