#JSONPathCLI

A cli program wrapping JSONPath, for easily querying json data. For more information on jsonpath see http://goessner.net/articles/JsonPath/

##Installation

npm install JSONPathCLI -g

##Usage

Accepts a jsonpath query as a parameter, and an optional filename to operate on

jsonpath $..* albums.json

If no file is provided it acts on stdin

cat albums.json | jsonpath $..*

Use the -c option to display a jsonpath cheatsheet

jsonpath -c

##Output

If the results are of a primitive type (string, number, boolean), they are output separated by a newline.

$ jsonpath $..author sample.json 
Nigel Rees
Evelyn Waugh
Herman Melville
J. R. R. Tolkien

$ jsonpath $..price sample.json 
8.95
12.99
8.99
22.99
19.95

If the results are javascript objects, or if the -j option is used to force json output, then the results are output as json (JSON.stringify)

$ jsonpath $..author sample.json -j
["Nigel Rees","Evelyn Waugh","Herman Melville","J. R. R. Tolkien"]

$ jsonpath $..book[2:] sample.json
[{"category":"fiction","author":"Herman Melville","title":"Moby Dick","isbn":"0-553-21311-3","price":8.99},{"category":"fiction","author":"J. R. R. Tolkien","title":"The Lord of the Rings","isbn":"0-395-19395-8","price":22.99}]

The -p option can be used to pretty-print the json output in for readability (util.inspect)

$ jsonpath $..book[2:] sample.json -p
[ { category: 'fiction',
    author: 'Herman Melville',
    title: 'Moby Dick',
    isbn: '0-553-21311-3',
    price: 8.99 },
  { category: 'fiction',
    author: 'J. R. R. Tolkien',
    title: 'The Lord of the Rings',
    isbn: '0-395-19395-8',
    price: 22.99 } ]
