python - python 中紧凑但漂亮的 JSON 输出？

Question

JSON 可以使用 indent=None(默认)作为单行(人眼无法读取)或使用 ident=N 在每个逗号后换行.

我希望看到的是更紧凑但仍然漂亮的输出，类似于 Common Lisp pretty-print 所做的。例如，而不是

 {
  "cleanup":{
   "cpu":6936.780000000001,
   "wall":7822.319401979446
  },
  "finished":"2017-08-14 18:36:23",
  "init":{
   "cpu":1365.73,
   "wall":1380.7802910804749
  },
  "job":"timings",
  "run":{
   "cpu":953.6700000000001,
   "wall":8350.496850013733
  },
  "started":"2017-08-14 13:28:06"
 }

我想看看

 {
  "cleanup":{"cpu":6936.780000000001,"wall":7822.319401979446},
  "finished":"2017-08-14 18:36:23",
  "init":{"cpu":1365.73,"wall":1380.7802910804749},
  "job":"timings",
  "run":{"cpu":953.6700000000001,"wall":8350.496850013733},
  "started":"2017-08-14 13:28:06"
 }

类似于pprint产生。

目前这是不可能的，但是当RFE: more compact pretty printing已实现，将使用 python-rapidjson 回答此问题.
