如何使用jq从json中提取数组作为TSV？答案

【问题标题】：How extract array of array as TSV from json using jq?如何使用jq从json中提取数组作为TSV？
【发布时间】：2020-01-31 07:01:33
【问题描述】：

我想从这里提取数据。

http://d2p2.pro/api/seqid/["P04637","P51608"]

我目前使用.[] | [ .[][0], .[][2]["disorder"]["consranges"][] ]。我明白了。

[
  "P04637",
  [
    "1",
    "22"
  ],
  [
    "26",
    "27"
  ],
  [
    "30",
    "31"
  ],
  [
    "33",
    "97"
  ],
  [
    "281",
    "329"
  ],
  [
    "343",
    "393"
  ]
]
[
  "P51608",
  [
    "1",
    "118"
  ],
  [
    "151",
    "281"
  ],
  [
    "283",
    "486"
  ]
]

但我想得到 TSV 格式的结果，就像这样。

P04637<TAB>1<TAB>22
P04637<TAB>26<TAB>27
...

有人知道以这种格式提取输出的正确 jq 命令是什么吗？

这是输出。所以 "try(.[][0]) | [.[0]] + (.[2].disorder.consranges[]) | @tsv" 取决于输入中条目的顺序。因此，它并不健壮。

$ jq -r "try(.[][0]) | [.[0]] + (.[2].disorder.consranges[]) | @tsv" < /tmp/1.json
P51608  1   118
P51608  151 281
P51608  283 486
$ jq -r "try(.[][0]) | [.[0]] + (.[2].disorder.consranges[]) | @tsv" < /tmp/2.json

【问题讨论】：

标签： arrays json export-to-csv jq

【解决方案1】：

以下过滤器产生的结果如下所示，与问题中的结果一致，因此希望这将为您提供所需的指导：

.[][0]
| [.[0]] + (.[2].disorder.consranges[])
| @tsv

输出

P04637  1   22
P04637  26  27
P04637  30  31
P04637  33  97
P04637  281 329
P04637  343 393
P51608  1   118
P51608  151 281
P51608  283 486

鲁棒化

在健壮性方面的要求不是很明确，但是散布一个或多个try 语句将赋予健壮性度量。以下将处理 Q 更新中的两个变体：

  .[][0]
  | try [.[0]] + (.[2].disorder.consranges[])
  | @tsv

灵活性

下面是一种在输入结构方面增加程序灵活性的方法的说明，根本不使用try：

.[][]
| .[0] as $p
| ..
| objects
| select(has("disorder"))
| [$p] + (.disorder.consranges[])
| @tsv

但要小心你的愿望！

【讨论】：

我不知道如何添加第三列。能给我看看吗？
谢谢。如何使查询对这个 URL d2p2.pro/api/seqid/["P01106"]> 处的空内容具有鲁棒性。
您可以（例如）为整个表达式添加前缀：try
没有。当某些记录仍然包含有效结果时，这将不起作用。不会打印任何结果（例如，d2p2.pro/api/seqid/["P51608","P01106"]>）
请参阅新章节。顺便说一句，您的稳健性要求不是（也不是）很清楚。
