A very handy and narrowly scoped utility to take the output from JSONStream for piping into tools like jq.
Tools like jq will otherwise hang waiting.
Basically it takes
[\n
{"field": "value"}\n
,\n
{"field": "value"}\n
... lots and lots of objects ...
,\n
]\nand makes it into:
{"field": "value"}\n
{"field": "value"}\n
... lots and lots of objects ...Let's say you have a very large source of JSON, maybe it's in a file; maybe it's something sending data over an http connection and that data has been piped through JSONStream.
On the receiving end it looks like this:
[
{"field": "value"}
,
... lots and lots of objects ...
,
]Now if you pipe this directly to jq it waits for the closing ] before it'll start outputting the stream.
This made me sad.
