我有一个＆＃34;深＆＃34;我要打印的案例类树＃34;像Scala＆＃34;源代码。

...因为我想查看，复制并粘贴它们以制作UnitTest

我正在使用lihaoyi's pprint来执行stringify的值，但是在几个级别之后，pprint停止打印。我已经检查了tokenize的内容，并且实例正在按原样发出;你可以看到字符串没有被删除。

我可以（手动）＆＃34;调整＆＃34;我的测试测试部分结果并得到我的漂亮来源，但......感觉不对。

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

@ pprint.pprintln(1 to 10, Int.MaxValue, Int.MaxValue) 
Range.Inclusive(1, 2, 3, 4, 5, 6, 7, 8, 9, 10)

正如文档中所提到的，这是一种在打印真正大数据结构时阻止内存错误的功能。
