Let's take a file with for example :



 "test": [
 
 
 ],
 "test": [
 
 "name":"bob",
 "age":21
 
 ]


Is there a way for a regex to minimize the code into something like this :



 "test": [],
 "test": ["name":"bob","age":21]





sed regular-expression json

    Why not use jq or some other appropriate tool? Regular expressions (chomsky type-3) and context-free languages (type-2) like JSON don't mix well.

  • The two documents are equivalent when parsed with a JSON parser. Use a JSON parser.

    I would not downvote this question. Been handling a bit of JSON with python, redis and bash lately and it is extremely hard to find simple and clear documentation to handle jq

Assuming the two keys test actually are unique (the second test would otherwise override the first test when parsing it with a JSON parser), and that the document is a well formed JSON document, use jq -c to produce a compact version of it.



Here, I've changed the names of the keys so that they are unique, and encapsulated the JSON fragment in an anonymous object:



$ cat file.json

 "test1": [
 
 ],
 "test2": [
 
 "name": "bob",
 "age": 21
 
 ]


$ jq -c . file.json
"test1":[],"test2":["name":"bob","age":21]


The . on the command line is a jq filter that passes the document through without modifying the contents.

  • Good answer, +1. The jq documentation is very convoluted, simple examples are more than needed.
