Streamson Bin

Splits stdout (in JSON format) according to given options. It is supposed to be memory efficient and fast to process.

Examples

Consider following context of input.json file:

{
	"books": [
		{"title": "title 1", "authors": ["author1@exmaple.com"]},
		{"title": "title 2", "authors": ["author2@example.com", "author3@example.com"]}
	]
}

Extract to stdout

cat input.json | streamson-bin -P '{"books"}[]'

Output:

{"books"}[0]: {"title": "title 1", "authors": ["author1@exmaple.com"]}
{"books"}[1]: {"title": "title 2", "authors": ["author2@example.com", "author3@example.com"]}

Extract to stdout without header

cat input.json | streamson-bin -p '{"books"}[]{"authors"}'

Output:

["author1@exmaple.com"]
["author2@example.com", "author3@example.com"]

Extract to file

cat input.json | streamson-bin -f '{"books"}[0]{}:/tmp/output.out'
cat /tmp/output.out

Output:

"title 1"
["author1@exmaple.com"]

Several matchers can be used

cat input.json | streamson-bin -p '{"books"}[]{"authors"}[]' -p '{"books"}[]{"title"}'

Output:

"title 1"
"author1@exmaple.com"
"title 2"
"author2@exmaple.com"
"author3@exmaple.com"
