@ckipp01 I suggest the following change to lines 68ff :
if sections.nonEmpty then
buf.append(System.lineSeparator + System.lineSeparator)
sections.foreach { section =>
buf.append(section)
buf.append(System.lineSeparator)
}
buf.toString
… markdown Currently if you have a simple scaladoc and you use `renderAsMarkdown` (which Metals does) to render markdown for hovers, there are extra newlines added that aren't necessary. Normally you can't tell as it seems some editors just trim off the extra newlines, but you can see in certain editors and in the REPL as well. _Notice how it removes two lines_ ```diff scala> :doc CanEqual Companion object containing a few universally known `CanEqual` instances. CanEqual instances involving primitive types or the Null type are handled directly in the compiler (see Implicits.synthesizedCanEqual), so they are not included here. - - ``` This just ensures that we add the extra two newlines only when we know we have more sections coming. fixes scalameta/metals#3740
