This is a problem with both the formatting code in io.github.intellij.dlanguage.features.formatter.DFormattingModelBuilder and the recursion taking place in DUtil::getPrevSiblingOfType

For now I've made a slight tweak but further investigation is needed.

SingingBush commented 3 years ago

The formatting code is another area that needs improving and testing. It's probably worth making proper use of

    override fun getRangeAffectingIndent(file: PsiFile, offset: Int, elementAtOffset: ASTNode): TextRange? {
        return null
    }

there needs to be a limit on how many times this method is called using recursion: https://github.com/intellij-dlanguage/intellij-dlanguage/blob/d2cbe3acbc3cdaecceb6ae9404368e63c6ee3047/src/main/java/io/github/intellij/dlanguage/utils/DUtil.java#L72-L81

Looks like a rewrite is needed to get rid of the recursion:

while(child != null) {
    if (child.getElementType() == type)
        return child.getTreePrev();
    child = child.getTreePrev();
}

return null;
