dmg Cookbook
============
Lightweight resource and provider to install OS X applications (.app) from dmg files.


Requirements
------------
### Platform
- Mac OS X


Resources/Providers
-------------------
### dmg_package

This resource will install a DMG "Package". It will retrieve the DMG from a remote URL, mount it using OS X's `hdid`, copy the application (.app directory) to the specified destination (/Applications), and detach the image using `hdiutil`. The dmg file will be stored in the `Chef::Config[:file_cache_path]`. If you want to install an application that has already been downloaded (not using the `source` parameter), copy it to the appropriate location. You can find out what directory this is with the following command on the node to run chef:

```bash
knife exec -E 'p Chef::Config[:file_cache_path]' -c /etc/chef/client.rb
```

Optionally, the LWRP can install an "mpkg" or "pkg" package using installer(8).

#### Actions
- :install - Installs the application.

#### Parameter attributes:
- `app` - This is the name of the application used by default for the /Volumes directory and the .app directory copied to /Applications.
- `source` - remote URL for the dmg to download if specified. Default is nil.
- `owner` - owner that should own the package installation.
- `destination` - directory to copy the .app into. Default is /Applications.
- `checksum` - sha256 checksum of the dmg to download. Default is nil.
- `type` - type of package, "app", "pkg" or "mpkg". Default is "app". When using "pkg" or "mpkg", the destination must be /Applications.
- `volumes_dir` - Directory under /Volumes where the dmg is mounted. Not all dmgs are mounted into a /Volumes location matching the name of the dmg. If not specified, this will use the name attribute.
- `package_id` - Package id registered with pkgutil when a pkg or mpkg is installed
- `dmg_name` - Specify the name of the dmg if it is not the same as `app`, or if the name has spaces.
- `dmg_passphrase` - Specify a passphrase to use to unencrypt the dmg while mounting.
- `accept_eula` - Specify whether to accept the EULA.  Certain dmgs require acceptance of EULA before mounting.  Can be true or false, defaults to false.

#### Examples
Install `/Applications/Tunnelblick.app` from the primary download site.

```ruby
dmg_package 'Tunnelblick' do
  source   'http://tunnelblick.googlecode.com/files/Tunnelblick_3.1.2.dmg'
  checksum 'a3fae60b6833175f32df20c90cd3a3603a'
  action   :install
end
```

Install Google Chrome. Uses the `dmg_name` because the application name has spaces. Installs in `/Applications/Google Chrome.app`.

```ruby
dmg_package 'Google Chrome' do
  dmg_name 'googlechrome'
  source   'https://dl-ssl.google.com/chrome/mac/stable/GGRM/googlechrome.dmg'
  checksum '7daa2dc5c46d9bfb14f1d7ff4b33884325e5e63e694810adc58f14795165c91a'
  action   :install
end
```

Install Dropbox. Uses `volumes_dir` because the mounted directory is different than the name of the application directory. Installs in `/Applications/Dropbox.app`.

```ruby
dmg_package 'Dropbox' do
  volumes_dir 'Dropbox Installer'
  source      'http://www.dropbox.com/download?plat=mac'
  checksum    'b4ea620ca22b0517b75753283ceb82326aca8bc3c86212fbf725de6446a96a13'
  action      :install
end
```

Install MacIrssi to `~/Applications` from the local file downloaded to the cache path into an Applications directory in the current user's home directory. Chef should run as a non-root user for this.

```ruby
directory "#{ENV['HOME']}/Applications"

dmg_package 'MacIrssi' do
  destination "#{ENV['HOME']}/Applications"
  action      :install
end
```

Install Virtualbox to `/Applications` from the .mpkg:

```ruby
dmg_package 'Virtualbox' do
  source 'http://dlc.sun.com.edgesuite.net/virtualbox/4.0.8/VirtualBox-4.0.8-71778-OSX.dmg'
  type   'mpkg'
end
```

Install pgAdmin to `/Applications` and automatically accept the EULA:

```ruby
dmg_package 'pgAdmin3' do
  source   'http://wwwmaster.postgresql.org/redir/198/h/pgadmin3/release/v1.12.3/osx/pgadmin3-1.12.3.dmg'
  checksum '9435f79d5b52d0febeddfad392adf82db9df159196f496c1ab139a6957242ce9'
  accept_eula true
end
```

Install Pivotal Tracker to `/Applications` using a password-protected dmg:

```ruby
dmg_package 'Pivotal Tracker' do
  volumes_dir    'tracker'
  source         'http://cheffiles.pivotallabs.com/fluid_tracker.dmg'
  dmg_passphrase 'xyz'
end
```

Install Silverlight, with idempotence check based on pkgutil:

```ruby
dmg_package 'Silerlight' do
  source     'http://silverlight.dlservice.microsoft.com/download/D/C/2/DC2D5838-9138-4D25-AA92-52F61F7C51E6/runtime/Silverlight.dmg'
  type       'pkg'
  checksum   '6d4a0ad4552d9815531463eb3f467fb8cf4bffcc'
  package_id 'com.microsoft.installSilverlightPlugin'
end
```
