jg

Simple command line tool for generating json documents.

Introduction

jg takes any number of command line arguments of the form key:value or key=value, and generates corresponding json.

eg:

$ jg 'a.b:[1,2]'

generates:

{
  "a": {
    "b": [
      1, 
      2
    ]
  }
}

The key is a . separated path describing the nested json objects to create.

The value can be any valid yaml value.

As a shortcut, you can follow relative to the last path by starting with a period, eg:

$ jg obj.field1:1 .field2:2

generates:

{
  "obj": {
    "field1": 1,
    "field2": 2 
  }
}

Curling

To pass the json as a POST body to curl (elasticsearch) do:

$ jg query.match_all:{} facets.myfacet.terms.field:field1 | curl localhost:9200/_search -d @-

Installation

Just copy jg into your path, eg:

$ sudo cp jg /usr/local/bin
