##Overview

This module adds resource types to manage settings in HOCON-style configuration files.

##Module Description

The hocon module adds a resource type so that you can use Puppet to manage settings in HOCON configuration files.

##Setup

##Beginning with hocon

To manage a HOCON file, add the resource type hocon_setting to a class.

##Usage

Manage individual settings in HOCON files by adding the hocon_setting resource type to a class. For example:

hocon_setting { "sample setting":
  ensure  => present,
  path    => '/tmp/foo.conf',
  setting => 'foosetting',
  value   => 'FOO!',
}

To control a setting nested within a map contained at another setting, provide the path to that setting under the "setting" parameter, with each level separated by a ".". So to manage barsetting in the following map

foo {
    bar {
        barsetting="FOO!"
    }
}

You would put the following in your manifest:

hocon_setting {'sample nested setting':
  ensure  => present,
  path => '/tmp/foo.conf',
  setting => 'foo.bar.barsetting',
  value   => 'BAR!',
}

You can also set maps like so:

hocon_setting { 'sample map setting':
  ensure => present,
  path => '/tmp/foo.conf',
  setting => 'hash_setting',
  value => { 'a' => 'b' },
}

##Reference

###Type: hocon_setting

Parameters

ensure: Ensures that the resource is present. Valid values are 'present', 'absent'.
name: An arbitrary name used as the identity of the resource.
path: The HOCON file in which Puppet will ensure the specified setting.
provider: The specific backend to use for this hocon_setting resource. You will seldom need to specify this --- Puppet will usually discover the appropriate provider for your platform. The only available provider for hocon_setting is ruby.
setting: The name of the HOCON file setting to be defined. This can be a top-level setting or a setting nested within another setting. To define a nested setting, give the full path to that setting with each level separated by a . So, to define a setting foosetting nested within a setting called foo contained on the top level, the setting parameter would be set to foo.foosetting.
value: The value of the HOCON file setting to be defined.
type: The type of the value passed into the value parameter. This value should be a string, with valid values being 'number', 'boolean', 'string', 'hash', 'array', and 'text'.

This parameter will not be need to be set most of the time, as the module is generally smart enough to figure this out on its own. There are only two cases in which this parameter is required.

The first is the case in which the value type is a single-element array. In that case, the type parameter will need to be set to 'array'. So, for example, to add a single-element array, you would add the following to your manifest
```
hocon_setting { 'single array setting':
  ensure => present,
  path => '/tmp/foo.conf',
  setting => 'foo',
  value => [1],
  type => 'array',
}
```
Since this type represents a setting in a configuration file, you can pass a string containing the exact text of the value as you want it to appear in the file (this is useful, for example, if you want to set a parameter to a map or an array but want comments or specific indentation on elements in the map/array). In this case, value must be a string with no leading or trailing whitespace, newlines, or comments that contains a valid HOCON value, and the type parameter must be set to 'text'. This is an advanced use case, and will not be necessary for most users. So, for example, say you want to add a map with particular indentation/comments into your configuration file at path foo.bar. You could create a variable like so
```
$map = 
"{
    # This is setting a
    a : b
    # This is setting c
        c : d
 }"
```
And your configuration file looks like so
```
baz : qux
foo {
  a : b
}
```
You could then write the following in your manifest
```
hocon_setting { 'exact text setting':
  ensure => present,
  path => '/tmp/foo.conf',
  setting => 'foo.bar',
  value => $map,
  type => 'text',
}
```
And the resulting configuration file would look like so
```
baz : qux
foo {
  a : b
  bar : {
      # This is setting a
      a : b
      # This is setting c
          c : d
  }
}
```
Aside from these two cases, the type parameter does not need to be set.

##Development

Puppet Labs modules on the Puppet Forge are open projects, and community contributions are essential for keeping them great. We can’t access the huge number of platforms and myriad of hardware, software, and deployment configurations that Puppet is intended to serve.

We want to keep it as easy as possible to contribute changes so that our modules work in your environment. There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things.

You can read the complete module contribution guide on the Puppet Labs wiki.

      may provide additional or different license terms and conditions
      for use, reproduction, or distribution of Your modifications, or
      for any such Derivative Works as a whole, provided Your use,
      reproduction, and distribution of the Work otherwise complies with

   5. Submission of Contributions. Unless You explicitly state otherwise,
      any Contribution intentionally submitted for inclusion in the Work
      by You to the Licensor shall be under the terms and conditions of
      this License, without any additional terms or conditions.
      Notwithstanding the above, nothing herein shall supersede or modify
      the terms of any separate license agreement you may have executed
      with Licensor regarding such Contributions.

   6. Trademarks. This License does not grant permission to use the trade
      names, trademarks, service marks, or product names of the Licensor,
      except as required for reasonable and customary use in describing the
      origin of the Work and reproducing the content of the NOTICE file.

   7. Disclaimer of Warranty. Unless required by applicable law or
      agreed to in writing, Licensor provides the Work (and each

      implied, including, without limitation, any warranties or conditions
      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
      PARTICULAR PURPOSE. You are solely responsible for determining the
      appropriateness of using or redistributing the Work and assume any
      risks associated with Your exercise of permissions under this License.

   8. Limitation of Liability. In no event and under no legal theory,
      whether in tort (including negligence), contract, or otherwise,
      unless required by applicable law (such as deliberate and grossly
      negligent acts) or agreed to in writing, shall any Contributor be
      liable to You for damages, including any direct, indirect, special,
      incidental, or consequential damages of any character arising as a
      result of this License or out of the use or inability to use the
      Work (including but not limited to damages for loss of goodwill,
      work stoppage, computer failure or malfunction, or any and all
      other commercial damages or losses), even if such Contributor
      has been advised of the possibility of such damages.

   9. Accepting Warranty or Additional Liability. While redistributing
      the Work or Derivative Works thereof, You may choose to offer,
      and charge a fee for, acceptance of support, warranty, indemnity,
      or other liability obligations and/or rights consistent with this
      License. However, in accepting such obligations, You may act only
      on Your own behalf and on Your sole responsibility, not on behalf
      of any other Contributor, and only if You agree to indemnify,
      defend, and hold each Contributor harmless for any liability
      incurred by, or claims asserted against, such Contributor by reason
      of your accepting any such warranty or additional liability.
