How to insert double quotes into String with interpolation in scala

You don't need to escape quotes in triple-quoted string, so s""""$value""""" will work. Admittedly, it doesn't look good either.

This is a bug in Scala:

escape does not work with string interpolation

but maybe you can use:

scala> import org.apache.commons.lang.StringEscapeUtils.escapeJava
import org.apache.commons.lang.StringEscapeUtils.escapeJava

scala> escapeJava("this is a string\nover two lines")
res1: java.lang.String = this is a string\nover two lines
