# 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`.
