辽一PPrint深树

Question

标题: Lihaoyi PPrint深层树

链接：辽一PPrint深树

我有一个“深”树的案例类，我想打印为“像Scala”源代码。

..。因为我想查看、复制和粘贴它们以生成UnitTest

我使用李浩毅(氏)来执行值的stringify，但是在几个级别之后，pprint停止了打印。我已经签入了tokenize，并且实例是按原样发出的；您可以看到字符串没有被拔除。

我可以(手动)“调整”我的测试，以测试部分结果，并获得我漂亮的源代码，但是.感觉不对。

原版“缺乏深度”打印

Module(
    Set(),
    Set(
        Material(
            "testTextLayoutContainer",
            List(
                Attribute("Position", VecSingle(2)),
                Attribute("UV", VecSingle(2)),
                Attribute("Color", VecFixed(4))
            ),
            List(
                UniformInstance("ProjMtx", MatSingle(4, 4)),
                UniformInstance("Texture", Texture(2, VecFixed(4)))
            ),
            Set(
                //
                // this is the line that's not being pprinted
                //

Answer 1

您可以提供一个高度和一个宽度，所以如果您提供一个足够大的值，它将显示它的全部。

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...

可以是

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

编辑：

正如在docs中提到的那样，这是一个在打印非常大的数据结构时停止内存错误的特性。
