prettyaml

This is a fork of json2yaml aimed at making the printed YAML prettier and more readable for the man on the streets.

Installation

npm install -g prettyaml

Note: To use npm and prettyaml you must have installed NodeJS.

Usage

Specify a file:

prettyaml ./example.json > ./example.yml

Or pipe from stdin:

curl -s http://foobar3000.com/echo/echo.json | prettyaml
wget -qO- http://foobar3000.com/echo/echo.json | prettyaml

Or require:

(function () {
  "use strict";
 
  var prettyaml = require('prettyaml')
    , ymlText
    ;
 
    ymlText = prettyaml.stringify({
      "foo": "bar"
    , "baz": "corge"
    });
 
    console.log(ymlText);
}());

Example

So, for all the times you want to turn JSON int YAML (YML):

{ "foo": "bar"
, "baz": [
    "qux"
  , "quxx"
  ]
, "corge": null
, "grault": 1
, "garply": true
, "wãldo": "false"
, "fred": "undefined"
}

becomes

foo: bar
baz:
  - qux
  - quxx
corge:
grault: 1
garply: true
"wãldo": "false"
fred: "undefined"

Note: In fact, both of those Object Notations qualify as YAML because JSON technically is a proper subset of YAML. That is to say that all proper YAML parsers parse proper JSON.

YAML can use either whitespace and dashes or brackets and commas.

For human readability, the whitespace-based YAML is preferrable. For compression and computer readability, the JSON syntax of YAML is preferrable.
