scala - How do I escape a newline in macro quasiquotes

Question

For example:

q"import scala.collection.mutable.Buffer\ndef foo: Buffer[Int] = ???"

This gives an error, because the newline characters is not resolved.

Answer 1

我的 tmp 目录中的示例：

    evals += q"""assert ($x.productArity >= ${args.length - 1},
    "Bad product arity ("+ $x.productArity +") for assignment")"""

或者，只使用一个半：

q"import scala.collection.mutable.Buffer; def foo: Buffer[Int] = ???"

您无法拼接已解析的内容。
