@eomm/archy

Render nested hierarchies npm ls style with unicode pipes.

This is a fork of substack/node-archy.
The original repository doesn't exist anymore - so here is my fork. This version has an additional feature to customize the fields name of obj input.

example

const archy = require('@eomm/archy');
const s = archy({
  label : 'beep',
  nodes : [
    'ity',
    {
      label : 'boop',
      nodes : [
        {
          label : 'o_O',
          nodes : [
            {
              label : 'oh',
              nodes : [ 'hello', 'puny' ]
            },
            'human'
          ]
        },
        'party\ntime!'
      ]
    }
  ]
});
console.log(s);

output

beep
├── ity
└─┬ boop
  ├─┬ o_O
  │ ├─┬ oh
  │ │ ├── hello
  │ │ └── puny
  │ └── human
  └── party
      time!

methods

const archy = require('@eomm/archy')

archy(obj, prefix='', opts={ labelField: 'label', nodesField: 'nodes' })

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.

You can customize the fields name of obj specifing a string in opts.labelField and opts.nodesField, so you don't need to adapt your tree.

install
