> A command-line JSON processor using Python syntax.

|
|
|
|
- Pretty-print JSON or JSON-Lines data from stdin to stdout:
|
|
|
|
`cat {{file.json}} | jello`
|
|
|
|
- Output a schema of JSON or JSON Lines data from stdin to stdout (useful for grep):
|
|
|
|
`cat {{file.json}} | jello -s`
|
|
|
|
- Output all elements from arrays (or all the values from objects) in JSON or JSON-Lines data from stdin to stdout:
|
|
|
|
`cat {{file.json}} | jello -l`
|
|
|
|
- Output the first element in JSON or JSON-Lines data from stdin to stdout:
|
|
|
|
`cat {{file.json}} | jello _[0]`
|
|
|
|
- Output the value of a given key of each element in JSON or JSON-Lines data from stdin to stdout:
|
|
|
|
`cat {{file.json}} | jello '[i.{{key_name}} for i in _]'`
|
|
|
|
- Output the value of multiple keys as a new JSON object (assuming the input JSON has the keys `key_name` and `other_key_name`):
|
|
|
|
`cat {{file.json}} | jello '{"{{my_new_key}}": _.{{key_name}}, "{{my_other_key}}": _.{{other_key_name}}}'`
|
|
|
|
- Output the value of a given key to a string (and disable JSON output):
|
|
|
|
`cat {{file.json}} | jello -r '"{{some text}}: " + _.{{key_name}}'`
