yamlprompt

A prompt that asks for yaml input.

Installation

npm install yamlprompt or npm install -g yamlprompt

Usage

test.js:

var yamlprompt = require('yamlprompt');
// Create readline interface
var rl = require('readline').createInterface(process.stdin, process.stdout);
rl.setPrompt('> ', 2);

yamlprompt(rl, function (err, obj) {
  if (err)
    throw err;

  // print the parsed yaml document
  console.log(obj);
});

This will give you a prompt, where you can type in yaml and it will print the corresponding JS object. Stop parsing input by typing ....

$ node test.js
> key: value,
> array: [ some, values, in, an, array ]
> array2:
>   - 1
>   - 2
> indentation: |
>   indented
> ...
{ key: 'value',
  array: [ 'some', 'values', 'in', 'an', 'array' ],
  array2: [ 1, 2 ],
  indentation: 'indented' }

There is also a binary that can be used from the command line. It converts the YAML input to JSON.

$ yamlprompt
> key: value
> ...
{
  "key": "value"
}

You can redirect it's output to a file.

$ yamlprompt > output.json
> key: value
> ...

You can also pass one file to the prompt to let it act like a conversion tool.

$ yamlprompt test.yml > output.json
