如何使用jq漂亮的打印，让多个值在同一行？ [英] How to pretty print using jq, so that multiple values are on the same line?

问题描述

  {
frameGrid：{
size ：[
 24，
 24 
]，
维度：[
 1，
 1 
]，
 姓名：[
 [
default
] 
] 
} 
} 
  pre> 
 
 
我想看到的更类似于：
 
 pre $  {
frameGrid：{
size：[24,24]，
dimensions：[1,1]，
names：[ default]] 
} 
} 
  

我知道这两种形式都是有效的，而jq有一个紧凑/漂亮的打印模式。但是中间有什么东西吗？我正在寻找格式化一个更大的json文件，有更多的数组值比这个，所以它很容易阅读和打印。也许我只是使用错误的工具来完成这项工作？

（请原谅可怕的格式选择，似乎code-sample不太喜欢json格式）虽然这可能是最好的使用像这样的工具

解决方案

如果你的json不是太复杂，你可以使用第二个jq调用来后处理第一个的输出。例如，如果您的数据在 data.json

  $ jq -M。 data.json | jq -MRsr'gsub（\\\
 +;）| gsub（\\\
];]）'
  

产生

  {
frameGrid：{
 size：[24,24]，
dimensions：[1,1]，
names：[[default]] 
} 
} 
  

What I get from jq is:

{
  "frameGrid": {
    "size": [
      24,
      24
    ],
    "dimensions": [
      1,
      1
    ],
    "names": [
      [
        "default"
      ]
    ]
  }
}

What I would like to see is something more like this:

{
  "frameGrid": {
    "size": [24,24], 
    "dimensions": [1,1],
    "names": [["default"]]
  }
}

I know both forms are valid, and that jq has a compact/pretty print mode. But is there something in-between? I'm looking to somehow format a larger json file that has many more array values than this, so that it's easily readable and printable. Maybe I'm just using the wrong tool for this job?

(please excuse the horrid formating choice. Seems code-sample doesn't like json formats much)

解决方案

While it is probably best to use a tool like the one peak suggested if your json isn't too complex you could use a second jq invocation to postprocess the output of the first. For example if your data is in data.json

$ jq -M . data.json | jq -MRsr 'gsub("\n      +";"")|gsub("\n    ]";"]")'

produces

{
  "frameGrid": {
    "size": [24,24],
    "dimensions": [1,1],
    "names": [["default"]]
  }
}
