#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
