.SYNOPSIS
   Retrieves installed vCheck plugins and available plugins from the Virtu-Al.net repository.

.DESCRIPTION
   Get-vCheckPlugin parses your vCheck plugins folder, as well as searches the online plugin respository in Virtu-Al.net.
   After finding the plugin you are looking for, you can download and install it with Add-vCheckPlugin. Get-vCheckPlugins
   also supports finding a plugin by name. Future version will support categories (e.g. Datastore, Security, vCloud)
     
.PARAMETER name
   Name of the plugin.

.PARAMETER proxy
   URL for proxy usage.
   
.PARAMETER proxy_user
   username for proxy auth.
   
.PARAMETER proxy_password
   password for proxy auth.
   
.PARAMETER proxy_domain
   domain for proxy auth.

.EXAMPLE
   Get list of all vCheck Plugins
   Get-vCheckPlugin

.EXAMPLE
   Get plugin by name
   Get-vCheckPlugin PluginName

.EXAMPLE
   Get plugin by name using proxy
   Get-vCheckPlugin PluginName -proxy "http://127.0.0.1:3128"

.EXAMPLE
   Get plugin by name using proxy with auth (domain optional depending on your proxy auth)
   Get-vCheckPlugin PluginName -proxy "http://127.0.0.1:3128" -proxy_user "username" -proxy_pass "password -proxy_domain "domain"

.SYNOPSIS
   Installs a vCheck plugin from the Virtu-Al.net repository.

.DESCRIPTION
   Add-vCheckPlugin downloads and installs a vCheck Plugin (currently by name) from the Virtu-Al.net repository. 

   The downloaded file is saved in your vCheck plugins folder, which automatically adds it to your vCheck report. vCheck plugins may require
   configuration prior to use, so be sure to open the ps1 file of the plugin prior to running your next report. 

.PARAMETER name
   Name of the plugin.

.EXAMPLE
   Install via pipeline from Get-vCheckPlugins
   Get-vCheckPlugin "Plugin name" | Add-vCheckPlugin

.EXAMPLE
   Install Plugin by name

.SYNOPSIS
   Retrieves configured vCheck plugin settings and exports them to CSV.

.DESCRIPTION
   Export-vCheckSettings will retrieve the settings from each plugin and export them to a CSV file.
   By default, the CSV file will be created in the vCheck folder named vCheckSettings.csv.
   You can also specify a custom path using -outfile.
   Once the export has been created the settings can then be imported via Import-vCheckSettings.

   By default, the CSV file is expected to be located in the vCheck folder named vCheckSettings.csv.
   You can also specify a custom path using -csvfile.
   If the CSV file is not found you will be asked to provide the path.
   The Setup Wizard will be disabled.
   You will be asked any questions not found in the export. This would occur for new settings introduced
   enabling a quick update between versions.

Get-vCheckCommand

# Below is a set of functions to make upgrading a vCheck directory easier

<#
    .SYNOPSIS
        Lists the variables in vCheck plugin files.

    .DESCRIPTION
        Plugin file will be scanned as a text file and any variables in between the "Start of Settings"
		and "End of Settings" section markers will be sent out the pipeline.  Files can be sent in
		via the pipeline or individually with a loop.  If using the "-Verbose" option for troubleshooting
		then using a loop is recommended.

    .PARAMETER  PluginFile
        The file to be processed.  Can be passed as text, a file object, or a set of files, such as 
		"Get-ChildItem *.ps1".

    .EXAMPLE
        Simple
		Get-vCheckVariablesSettings -PluginFile "c:\scripts\vcheck6\vcenter\Plugins\20 Cluster\75 DRS Rules.ps1"

		Recursed
		Get-ChildItem -Path E:\vCheckLatestTesting -File -Filter *.ps1 -Recurse | % { Get-vCheckVariablesSettings -PluginFile $_.FullName }

    .INPUTS
        System.IO.FileInfo

    .OUTPUTS
        File		Selected.System.Management.Automation.PSCustomObject	The 'Fullname' property from the plugin file.
		Variable	Selected.System.Management.Automation.PSCustomObject	The text of the variable assignment from the plugin file.

    .NOTES
        With multiple vCheck directories to upgrade I needed an easy to pull the variables used 
		in the old vCheck installation to go into the new version.

    .SYNOPSIS
        Matches the disabled plugins in a target directory with those in a source directory.

    .DESCRIPTION
        I wrote it for when I'm upgrading vCheck.  This will go through the old directory and
		any plugin marked as disabled there will be marked as disabled in the new directory.

    .PARAMETER  OldVcheckDir
        What you you think it is.

    .PARAMETER  NewVcheckDir
        No tricks here.

	.EXAMPLE
        Sync-vCheckDisabledPlugins -OldVcheckDir c:\scripts\vcheck6\vccenter_old_20150218_163057 -NewVcheckDir c:\scripts\vcheck6\vcenter

    .SYNOPSIS
        Lists the disabled plugins in a target directory.

    .DESCRIPTION
        Essentially a stripped down version of Sync-vCheckDisabledPlugins I threw it in
		in case	someone found it useful.

    .PARAMETER  VcheckDir
        What you you think it is.

        Get-vCheckDisabledPlugins -VcheckDir c:\scripts\vcheck6\vcenter

<#
    .SYNOPSIS
        Does most of the work upgrading to a new version of vCheck.

    .DESCRIPTION
        This function will:
		  -Backup the current directory by renaming it with the current date
		  -Copy in the new version from a directory you've specified
		  -Save all the variable settings to a text file
		  -Set the same disabled plugins in the new version
		  -Opens the saved variable settings in Notepad
		  
		Then run vCheck.ps1 for the first time to configure it using the 
		variables listing open in Notepad as a reference.

    .PARAMETER  CurrentvCheckPath
        Directory to be upgraded.

    .PARAMETER  NewvCheckSource
		Location of the new version downloaded from GitHub.
	
    .EXAMPLE
        Upgrade-vCheckDirectory -CurrentvCheckPath c:\scripts\vcheck6\vcenter -NewvCheckSource c:\scripts\vcheck6\vcenter\vCheck-vSphere-master

    .NOTES
        If you have multiple directories and some settings like smtp server
	are the same for them all you could upgrade the file(s) in the new
	vCheck version directory and they'll be copied out with each upgrade.
	
	This is my process for upgrading vCheck with this function.
	  1.  Extract a new, unmodified version of the vCheck to a directory.  For this example "C:\Scripts\vCheck\vCheck-vSphere-master".
	  2.  Load the utility - ". C:\Scripts\vCheck\vCheck-vSphere-master\vCheckUtils.ps1" .
	  3.  Upgrade-vCheckDirectory –CurrentvCheckPath C:\Scripts\vcheck\vcenterprod -NewvCheckSource C:\Scripts\vcheck6\vCheck-vSphere-master
	  4.  The list of plugin variable values is automatically opened in Notepad.
	  5.  Change directory to C:\Scripts\vcheck\vcenterprod .
	  6.  Run vCheck.ps1 .  Input all the prompts for variable values with the ones in the file opened by Notepad.  For the global variable “ $EmailFrom = "vcheck-vcenter@monster.com" ” I use my own email address until after I done a test run.  Then I change it back to the group email address.
	  7.  After all the variable have been entered vCheck will run.
	  8.  Review the PowerShell console for script errors and the vCheck email report for any problems.  
	  9.  If there are not problems set the “EmailFrom” variable in “GlobalVariables.ps1” back to it’s original value.
