jiffy-json

A cli for easily building JSON.

Installation

The program is a single script, written in python. You will need python2.7 on your path.

You can download the script by itself or clone the repo. Add it to your path somehow and alias or symlink it to jj if you like.

curl https://raw.githubusercontent.com/danthegoodman/jiffy-json/master/jiffy-json -o jiffy-json

Quick Documentation:

Primitives:

Each argument represents the key and value for an item in the json output. They are separated a colon.

Generally, the values are considered strings. However, some patterns have been been given special treatment:

• true and false, which turn into the boolean values
• null, which turns into null.
• [], which is an empty array
• {}, which is an empty object
• any number, which turns into the number.

> jiffy-json name:"Sophie Hatter" gender:female age:20 isMarried:false
{"name":"Sophie Hatter","gender":"female","age":20,"isMarried":false}

This type detection may be overridden by specifying the key as an explicit string.

> jiffy-json 'pi(s):3.14'
{"pi":"3.14"}

Objects:

As seen above, multple arguments may be given to form an object. If a key is a period separated path, nested objects will be generated.

> jiffy-json type:'Tesla Model S' features.cruiseControl:true features.autoPilot:true
{"type":"Tesla Model S","features":{"cruiseControl":true,"autoPilot":true}}

Arrays:

In the key path, you may use [0] to generate arrays.

> jiffy-json pets[0]:Spot pets[1]:Porthos
{"pets":["Spot", "Porthos"]}

You can also use a "push" syntax by omitting the index. This will append values to the array.

> jiffy-json pets[]:Spot pets[]:Porthos
{"pets":["Spot", "Porthos"]}
