我有一个案例 类 的 "deep" 树，我想将其打印为 "like Scala" 源代码。
... because I want to view, copy and paste them to make a UnitTest
我正在使用 lihaoyi's pprint 执行值的 stringify，但是 几个级别后，pprint 停止 打印。
我已经检查了 tokenize 的东西，并且实例按原样发出；你可以看到字符串没有被删除。
我可以（手动）"tweak" 我的测试来测试部分结果并获得我的漂亮来源，但是......感觉不对。
原始"Lack of deep"打印输出

您可以提供高度和宽度，因此如果您提供足够大的值，它将显示所有内容。
scala> pprint.pprintln(Seq(1, 2, 3), width = Int.MaxValue, height = Int.MaxValue)
所以
@ pprint.pprintln(1 to 10, 3, 10)
Range.Inclusive(
1,
2...
可以
