=========
### Offers convenient getters and setters for the stat `mode`
[![Build Status](https://travis-ci.org/TooTallNate/stat-mode.svg?branch=master)](https://travis-ci.org/TooTallNate/stat-mode)

You know that `mode` property on the `fs.Stat` object that you probably
usually just ignore? Well there's acutally a lot of information packed
into that number.

The specific information includes:

 * What the ["file type"](http://en.wikipedia.org/wiki/Unix_file_types) of file it is
 * Whether or not the [`setuid` and `setgid` bits](http://en.wikipedia.org/wiki/Setuid) are set
 * Whether or not the [`sticky` bit](http://en.wikipedia.org/wiki/Sticky_bit) is set
 * The [_read_, _write_, and _execute_ permissions for the _owner_, _group_ and _others_](http://en.wikipedia.org/wiki/File_system_permissions)

This module helps you extract that information.

All the getters are also setters, which change the `mode` property
appropriately. This is useful for when you have to build up your
own `fs.Stat` object for whatever reason (like when implementing a
FUSE filesystem.


Installation
------------

``` bash
$ npm install stat-mode
```


Example
-------

So given some arbitrary file (let's say `/bin/echo`):

``` bash
$ ls -l /bin/echo
-rwxr-xr-x 1 root wheel 14128 Aug 11  2013 /bin/echo
```

We can inspect it using the `fs.stat()` call and creating a `Mode` instance
on top of it.

``` javascript
var fs = require('fs');
var Mode = require('stat-mode');

fs.stat('/bin/echo', function (err, stat) {
  if (err) throw err;

  // create a "Mode" instance on top of the `stat` object
  var mode = new Mode(stat);

  // you can check what kind of file it is:
  mode.isDirectory();
  // false

  mode.isFIFO();
  // false

  mode.isFile();
  // true


  // and you can also check individual owner, group and others permissions
  mode.owner.read;
  // true

  mode.owner.write;
  // true

  mode.owner.execute;
  // true

  mode.group.read;
  // true

  mode.group.write;
  // false

  mode.group.execute;
  // true

  mode.others.read;
  // true

  mode.others.write;
  // false

  mode.others.execute;
  // true


  // the `toString()` output resembes the `ls -l` output:
  mode.toString();
  // '-rwxr-xr-x'
});
```


API
---

### new Mode(Object stat) → Mode

You must pass in "stat" object to the `Mode` constructor. The "stat"
object can be a real `fs.Stat` instance, or really any Object with a
`mode` property.

#### mode.isDirectory([Boolean set]) → Boolean

Returns `true` if the mode's file type is "directory", `false` otherwise.
If you pass `true` to the function, then the mode will be set to "directory".

#### mode.isFile([Boolean set]) → Boolean

Returns `true` if the mode's file type is "file", `false` otherwise.
If you pass `true` to the function, then the mode will be set to "file".

#### mode.isBlockDevice([Boolean set]) → Boolean

Returns `true` if the mode's file type is "block device", `false` otherwise.
If you pass `true` to the function, then the mode will be set to "block device".

#### mode.isCharacterDevice([Boolean set]) → Boolean

Returns `true` if the mode's file type is "character device", `false` otherwise.
If you pass `true` to the function, then the mode will be set to "character
device".

#### mode.isSymbolicLink([Boolean set]) → Boolean

Returns `true` if the mode's file type is "symbolic link", `false` otherwise.
If you pass `true` to the function, then the mode will be set to "symbolic link".

#### mode.isFIFO([Boolean set]) → Boolean

Returns `true` if the mode's file type is "FIFO", `false` otherwise.
If you pass `true` to the function, then the mode will be set to "FIFO".

#### mode.isSocket([Boolean set]) → Boolean

Returns `true` if the mode's file type is "socket", `false` otherwise.
If you pass `true` to the function, then the mode will be set to "socket".

#### mode.owner.read → Boolean [Getter/Setter]

`true` if the mode is "owner read" rights, `false` otherwise.

#### mode.owner.write → Boolean [Getter/Setter]

`true` if the mode is "owner write" rights, `false` otherwise.

#### mode.owner.execute → Boolean [Getter/Setter]

`true` if the mode is "owner execute" rights, `false` otherwise.

#### mode.group.read → Boolean [Getter/Setter]

`true` if the mode is "group read" rights, `false` otherwise.

#### mode.group.write → Boolean [Getter/Setter]

`true` if the mode is "group write" rights, `false` otherwise.

#### mode.group.execute → Boolean [Getter/Setter]

`true` if the mode is "group execute" rights, `false` otherwise.

#### mode.others.read → Boolean [Getter/Setter]

`true` if the mode is "others read" rights, `false` otherwise.

#### mode.others.write → Boolean [Getter/Setter]

`true` if the mode is "others write" rights, `false` otherwise.

#### mode.others.execute → Boolean [Getter/Setter]

`true` if the mode is "others execute" rights, `false` otherwise.
