Get-​Ise​Snippet

Gets snippets that the user created.

Syntax

Get-IseSnippet []

Description

The Get-IseSnippet cmdlet gets the PS1XML files that contain reusable text snippets that the user created. It works only in Windows PowerShell Integrated Scripting Environment (ISE).

When you use the New-IseSnippet cmdlet to create a snippet, New-IseSnippet creates a <SnippetTitle>.Snippets.ps1xml file in the $home\Documents\WindowsPowerShell\Snippets directory. Get-IseSnippet gets the snippet files in the Snippets directory.

This cmdlet does not get built-in snippets or snippets that are imported from modules through the Import-IseSnippet cmdlet.

This cmdlet was introduced in Windows PowerShell 3.0.

Examples

Example 1: Get all user-defined snippets

PS C:\> Get-IseSnippet

This command gets all user-define snippets in the Snippets directory.

Example 2: Copy all user-defined snippets from remote computers to a shared directory

PS C:\> Invoke-Command -Computer (Get-Content Servers.txt) {Get-IseSnippet | Copy-Item -Destination \\Server01\Share01\Snippets}

This command copies all of the user-created snippets from a group of remote computers to a shared Snippets directory.

The command uses the Invoke-Command cmdlet to run a Get-IseSnippet command on the computers in the Servers.txt file. A pipeline operator (|) sends the snippet files to the Copy-Item cmdlet, which copies them to the directory that is specified by the Destination parameter.

Example 3: Display the title and text of each snippet on a local computer

PS C:\> #Parse-Snippet Function

function Parse-Snippet
{
  $SnippetFiles = Get-IseSnippet
  $SnippetNamespace = @{x="http://schemas.microsoft.com/PowerShell/Snippets"}
  foreach ($SnippetFile in $SnippetFiles)
   {
     Write-Host ""
     $Title = Select-Xml -Path $SnippetFile.FullName -Namespace $SnippetNamespace -XPath "//x:Title" | foreach {$_.Node.InnerXML}
     $Text =  Select-Xml -Path $SnippetFile.FullName -Namespace $SnippetNamespace -XPath "//x:Script" | foreach {$_.Node.InnerText}
     Write-Host "Title: $Title"
     Write-Host "Text: $Text"
   }
}

# Sample Output

Title: Mandatory
Text:
Param
(
  [parameter(Mandatory=True)]
  [String[]]
  $<ParameterName>
)

Title: Copyright
Text:  (c) Fabrikam, Inc. 2012

This example uses the Get-IseSnippet and Select-Xml cmdlets to display the title and text of each snippet on the local computer.

Example 4: Display the title and description of all snippets in the session

PS C:\> $PSISE.CurrentPowerShellTab.Snippets | Format-Table DisplayTitle, Description

This command displays the title and description of all snippets in the session, including built-in snippets, user-defined snippets, and imported snippets.

The command uses the Windows PowerShell ISE object model. The $PSISE variable represents the Windows PowerShell ISE host program. The CurrentPowerShellTab property of the $PSISE variable represent the current session. The Snippets property represents snippets in the current session.

The $PSISE.CurrentPowerShellTab.Snippets command returns a Microsoft.PowerShell.Host.ISE.ISESnippet object that represents a snippet, unlike the Get-IseSnippet cmdlet, which returns a file object (System.Io.FileInfo) that represents a snippet file.

The command also uses the Format-Table cmdlet to display the DisplayTitle and Description properties of the snippets in a table.

Outputs

System.IO.FileInfo

This cmdlet returns a file object that represents the snippet file.

Notes

  • The New-IseSnippet cmdlet stores new user-created snippets in unsigned .ps1xml files. As such, Windows PowerShell cannot add them to a session in which the execution policy is AllSigned or Restricted. In a Restricted or AllSigned session, you can create, get, and import unsigned user-created snippets, but you cannot use them in the session.

    To use unsigned user-created snippets that the Get-IseSnippet cmdlet returns, change the execution policy, and then restart Windows PowerShell ISE.

    For more information about Windows PowerShell execution policies, see about_Execution_Policies.
