# example

``` js
var archy = require('archy');
var s = archy({
  label : 'beep',
  nodes : [
    'ity',
    {
      label : 'boop',
      nodes : [
        {
          label : 'o_O',
          nodes : [
            {
              label : 'oh',
              nodes : [ 'hello', 'puny' ]
            },
            'human'
          ]
        },
        'party\ntime!'

# methods

var archy = require('archy')

## archy(obj, prefix='', opts={})

Return a string representation of `obj` with unicode pipe characters like how
`npm ls` looks.

`obj` should be a tree of nested objects with `'label'` and `'nodes'` fields.
`'label'` is a string of text to display at a node level and `'nodes'` is an
array of the descendents of the current node.

If a node is a string, that string will be used as the `'label'` and an empty
array of `'nodes'` will be used.

`prefix` gets prepended to all the lines and is used by the algorithm to
recursively update.

If `'label'` has newlines they will be indented at the present indentation level
with the current prefix.

To disable unicode results in favor of all-ansi output set `opts.unicode` to
`false`.
