[英]Flatten nested Json objects with JQ
I am creating a script to transform JSON objects to "string" files (for translation purposes). 我正在创建一个脚本来将JSON对象转换为“字符串”文件(用于翻译目的)。 the idea is to transform:
想法是转变:
{
"TRANSLATION1": "text1",
"TRANSLATION2": "text2"
}
into 成
"TRANSLATION1" = "text1";
"TRANSLATION2" = "text2";
That was done with : jq -r 'to_entries|map("\\"\\(.key)\\"=\\(.value|tojson);")|.[]'
这完成了:
jq -r 'to_entries|map("\\"\\(.key)\\"=\\(.value|tojson);")|.[]'
Nice! 太好了!
Now, my problem is with nested objects: 现在,我的问题是嵌套对象:
{
"TRANSLATION1": "text1",
"TRANSLATION2": "text2",
"TRANSLATION3": {
"SUBTRANS1": "subtranslation1",
"SUBTRANS2": "subtranslation2",
}
}
I would like to have as result: 我希望得到结果:
"TRANSLATION1" = "text1";
"TRANSLATION2" = "text2";
"TRANSLATION3.SUBTRANS1" = "subtranslation1";
"TRANSLATION3.SUBTRANS2" = "subtranslation2";
Can anyone help?! 有人可以帮忙吗?! I have been scratching my head for hours now...
我现在已经摸不着头几个小时了......
One approach would be to use tostream
: 一种方法是使用
tostream
:
tostream
| select(length==2)
| (.[0] | join(".")) as $k
| .[1] as $v
| "\"\($k)\" = \"\($v)\";"
When used with the -r command-line option, this will produce the desired results, assuming the input is valid JSON. 当与-r命令行选项一起使用时,假设输入是有效的JSON,这将产生所需的结果。
It might be worth making explicit that the output format may not be very useful if any key name contains a period, so it might be worth checking that this is indeed the case, eg as follows: 可能值得明确的是,如果任何键名包含句点,则输出格式可能不是非常有用,因此可能值得检查确实是这种情况,例如如下:
[.. | objects | keys_unsorted[]]
| map(select(index(".")))
| unique[]
tostream
tostream
paths as $path
| getpath($path)
| strings
| "\"\($path|join("."))\" = \"\(.)\";"
