README
treeify  
=======
[](https://travis-ci.org/notatestuser/treeify)
_treeify_ converts a JS object into a nice, visible depth-indented tree for console printing. The structure
generated is similar to what you get by running the ```tree``` command on Unixy platforms.
```
{
oranges: {
'mandarin': { ├─ oranges
clementine: null, │ └─ mandarin
tangerine: 'so cheap and juicy!' -=> │ ├─ clementine
} │ └─ tangerine: so cheap and juicy!
}, └─ apples
apples: { ├─ gala
'gala': null, └─ pink lady
'pink lady': null
}
}
```
It also works well with larger nested hierarchies such as file system directory trees.
In fact, the ```fs_tree``` example does a pretty good job of imitating ```tree```. Try it out!
See the other included examples or the test suite for usage scenarios.
Getting it
----------
### For use with node.js
First you'll want to run this command in your project's root folder:
```
$ npm install treeify
```
Then proceed to use it in your project:
```js
var treeify = require('treeify');
console.log(
treeify.asTree({
apples: 'gala', // ├─ apples: gala
oranges: 'mandarin' // └─ oranges: mandarin
}, true)
);
```
### For use in a browser
Treeify cooperates with Node, AMD or browser globals to create a module. This means it'll work
in a browser regardless of whether you have an AMD-compliant module loader or not. If such
a loader isn't found when the script is executed, you may access Treeify at ```window.treeify```.
Usage
-----
The methods exposed to you are as follows, in a strange kind of signature notation:
### asLines()
```js
treeify.asLines(obj, showValues (boolean), [hideFunctions (boolean),] lineCallback (function))
// NOTE: hideFunctions is optional and may be safely omitted - this was done to ensure we don't break uses of the previous form
```
### asTree()
```js
treeify.asTree(obj, showValues (boolean), [hideFunctions (boolean)]): String
```
Running the tests
-----------------
There's a pretty extensive suite of Vows tests included.
```
$ npm test
```
