Chocolatey 0.9.9+ deprecated support for the `webpi` custom source, so I needed to write this.
[Windows Web Platform Installer](http://www.microsoft.com/web/downloads/platform.aspx) is a way of installing products and applications for Microsoft IIS on Windows. It has a [command line](http://www.iis.net/learn/install/web-platform-installer/web-platform-installer-v4-command-line-webpicmdexe-rtw-release); this ansible module allows IIS modules to be installed via this means.
To find out names of modules, use `webpicmd /list /listoption:available`.
Notes:
* `webpicmd` must be installed and on `PATH` first (see `win_chocolatey` module; package is `webpicmd`)
* `webpicmd` does not allow modules to be uninstalled
* IIS must be installed first (see `win_feature` module; package is `Web-Server`)
* Installations will
* accept EULA (which otherwise requires user input)
* suppress reboots (so you have to manage those; see `win_reboot` module)
This changes the get-attr function slightly, and lets the module specify whether a param is needed and auto-fails if it is not present. A module can now verify params like so::
$params = Parse-Args $args;
$result = New-Object psobject;
Set-Attr $result "changed" $false;
$path = Get-Attr -obj $params -name path -failifempty $true -resultobj $result
or
$params = Parse-Args $args;
$result = New-Object psobject;
Set-Attr $result "changed" $false;
$path = Get-Attr -obj $params -name path -failifempty $true -emptyattributefailmessage "Oh man. You forgot the main part!" -resultobj $result
slight tweak in how the powershell module converts to json in order to support nested objects (allows for more complex facts, among others)
This script gathers some extended facts on windows hosts in a json array attribute called "ansible_interfaces". This info is needed for some network-related modules I'm working on. Required the update to powershell.ps1 to return deeply nested json objects.
