Most of this post is also based on the Microsoft?s Windows PowerShell Quick Reference however despite the sharing scripting runtimes the nature of the both shells differ considerably as described in the previous post: Sitecore PowerShell Console cheat sheet ? Part 1. In all cases where it made sense I?ve converted the samples to establish them in Sitecore scenarios.

How to Write Conditional Statements

To write an If statement use code similar to this:

$page = Get-item .;
$changedBy = $page."__Updated by";

if ($changedBy -eq "")
  { "Unspecified author - a system page?" }
elseif ($changedBy -eq $me)
  { "The page has been last edited by me!" }
else
  { "The page has been last edited by "+ $changedBy }

Instead of writing a series of If statements you can use a Switch statement, which is equivalent to VBScript?s Select Case statement:

$page = Get-Item .;
switch ($page.Language) {
    "en" {"This version is in English"}
    "pl" {"This version is in Polish"}
    "tlh-KX" {"This version is in Klingon?!"}
    default {"No idea what this language is!"}
  }

I?m realizing time and time again that the learning curve for PowerShell can be steep without a proper guidance. While most people I talk to are very excited about the concept they become discouraged after a having some tries and not realizing its full potential. Therefore I decided it?s worth spending some time introducing some basic principles to help scripting alleviate some of the initial pains.

I have gathered some literature available for free about the topic of PowerShell in general you might want to read, but I also think that a distillation of the basic concepts is really important so you can have some quick wins while you begin your PowerShell journey.

A great deal of this post is a port of my older post for similar console for EPiServer, but since the differences are significant enough to confuse Sitecore developers if I sent them to the original version, I?ve decided to create a proper Sitecore cheat sheet.   Most of this is based on the Microsoft?s Windows PowerShell Quick Reference however despite the sharing scripting runtimes the nature of the both shells are pretty different (although the differences are not as vast as one might think).

That said, I considered that enough of the Reference document is irrelevant in the Sitecore scenario that it?s beneficial for the users of the console to have a bespoke cheat sheet created especially for the purpose of this plugin.

The content & samples of the original cheat sheet has been adjusted to more closely reflect scenarios usable for an Sitecore admin or developer.

A few days back a budy from our Sitecore team has alerted me to this interesting question on StackOverflow which asks for automation of content promotion from one Sitecore instance to another. He suggested – and rightly so ? that the PowerShell Console could be used in that scenario. While this was always possible by simply writing it as a PowerShell code the latest version of the console added a few commandlets making building packages much easier.

The easiest approach is to build the package visually in the package designer, save it and then simply use the console to read it and generate the installation zip like:

get-package "powershell console.xml" `
  | Export-Package -FileName "PowerShell Console.zip" -Zip

That?s fine in most cases but if you have some more complex scenarios or want to generate some custom packages ? you might want to generate packages directly in PowerShell.

To Create a Package you simply use:

$package = new-package "Test Package";

Now that you have that package you might want to add some files and items to it.

Let’s add for example our item templates by querying the master database and creating a dynamic item source:

$TemplatesSource = get-childitem "master:/templates/Cognifide" `
  | New-ItemSource "Cognifide Templates";

And subsequently add it to our new package:

$package.Sources.Add($TemplatesSource);

While that by itself is fairly useful, the really cool part is that you have a full flexibility of PowerShell at your disposal when you create a source with static items. Let?s say you want to add all items of template ?Article Template? that reside anywhere under your ?home? node ? now that would require quite a bit of clicking in the Package Designer, but is trivial with the PowerShell Console:

$ArticlesSource = get-childitem master:/content/home/about-us/* -recurse `
  | where-object { $_.TemplateName -match "ArticleTemplate" } `
  | New-ExplicitItemSource "Cognifide Articles";

$package.Sources.Add($ArticlesSource);

You can specify any automation or filter you can think of to your Get-ChildItem, and you really don?t have to skimp on the number of data sources ? after all you can re-generate your package at any time!

Similarly you can do this to the files on disk. Let?s say ? you want to add all .aspx, .ascx and .ashx files, just to make sure your deployment features all the latest code and for the sake of this example let?s assume your UI elements are located in the Layouts folder under your web application:

$LayoutsPath = $AppPath+"layouts\*"
$Layouts = get-childitem $LayoutsPath -include "*.as?x" -recurse -force `
  | New-ExplicitFileSource "My Layouts";
$package.Sources.Add($Layouts);

Easy enough? now let?s add everything that is within the bin folder as a dynamic file source:

$BinFolder = New-FileSource "Bin Folder" -Root "/bin"
$package.Sources.Add($BinFolder);

That is it really? you may want to specify your package metadata which you would do like:

$package.Metadata.Author = "Auto generated " + `
  [DateTime]::Now.ToShortDateString();
$package.Metadata.Comment = "Isn't it cool?!";
$package.Metadata.Publisher = "Cognifide";

and then save it for later opening in package designer:

$package | Export-Package -FileName "test package.xml"

alternatively you can open such package as specified earlier

get-package "test package.xml"

if you ever wanted to add more sources to it or export as a zip file to be imported with the assets in your target environment:

$package | Export-Package -FileName "test package.zip" -Zip

? now on your target machine you need to upload your package to the Data\Packages folder. But then to install it all it takes is:

Import-Package "test package.zip"

Obviously all of it can be hooked to ribbon, context items, or be scheduled? but I get ahead of myself…

So how does it all relate to continuous deployment?

All of this can be completely automated, all you need to do is create a Script item as described in one of my previous posts and call the PowerShell execution URL referencing your script from your CruiseControl server or whichever continuous integration product you use in a fashion similar to:

http://myhost/Console/Layouts/PowerShellResults.aspx?scriptId={1680E211-BD28-49BE-82FB-DA7232814C62}&scriptDb=web

You need to deal with the fact that you are most probably not logged in with your continuous delivery environment ? in this case probably best approach is to use the web database or the script item my turn out to be unavailable to you and the script will not execute.

Now in your source environment your script will create the package and upload it to an FTP server (there is plenty of ways to do this from PowerShell? you can find a couple of samples on Stack Overflow) and subsequently call a second part of the script on the target server.

On the Target server ? a complementary script will be executed in the similar fashion ? by the originating server and if you don?t have direct access to the file on the FTP server you?ve just uploaded ? you can download it and import the package.

Now if you integrate the script with a ribbon in Content Editor on the source server (like described in the previous post) you can have a one-click-deployment solution on your dev machine, but then the REALLY cool part would be to integrate it with the context menu (as described in this post) and be able to push parts of the site to production with a single click! Not to mention your nightlies can really be nightlies if you do it using the scheduled tasks integration.

So now that you can easily create the menus and ribbons executing PowerShell scripts, it might be a good time to do some more administrative tasks? let?s start with scheduled tasks. I?m not going to go deep into the task scheduling, you can find an excellent post by John West on his blog regarding task scheduling. Currently the PowerShell module supports one of the ways described in the post ? the section describing how to configure them is called ?Scheduled Tasks? in the blog.

The module comes with an out-of-the-box PowerShell script command as you can see

You don?t need to create any additional commands, instead you only need to create a script and a schedule for it and the existing command will handle all of them. In my example I wanted to trim all recycle bin items every night.

Let?s get cracking?

Sitecore is built from the grounds up with extendibility in mind. Be that plugging into any place in its internal pipelines or any aspect of its User eXperience, therefore when I?ve managed to extend it?s context menu, I expected to have no problems whatsoever doing the same to its ribbon. Mind you I was right?

Using the PowerShell Console Module it took me less than 10 minutes total to add a nice piece of functionality that I thought was missing ? Publish items I have modified.

Similarly to extending context menu ? first I?ve created the script I wanted to execute that will take the current item and it?s sub-items and publish them by adding a new script item using the /sitecore/templates/Cognifide/PowerShell Script template in the core database. I?ve put it in the same place I store all my my scripts – in the /sitecore/content/Applications/PowerShell Console/Scripts branch but feel free to store them anywhere in the tree.

• Filled in the Script body part with my script.
• I decided I want to see the publishing results as I want to verify if the items I expected got published.

Now the UI integration bits?

Since I wanted it nicely integrated with the publish button – I?ve created a Publish My Items item of template /sitecore/templates/System/Menus/Menu item within the /sitecore/content/Applications/Content Editor/Menues/Publish/ branch in the core database, set it?s icon and reference the script item in the Message field using the following pattern:

item:executescript(id=$Target,script={0937769B-998D-4580-B9FE-730C4CDABECD},scriptDb=core)

where the script guid is the ID of your script and the scriptDb is the database the script is located in.

That?s it really. You can download the solution but I would strongly recommend you try the manual approach ? it?s really exciting to see the puzzles click in.

The solution requires the Sitecore PowerShell Console from Cognifide, available for free from Sitecore Shared Source site.

In the he latest update of PowerShell Console for Sitecore, I?ve started experimenting with further integration ? context scripts. What is that and what can it do for you?

You can safely assume PowerShell is not something your regular users will aspire to learn, but it does not mean they cannot harness its power if you enable them to.

If you look closely at the latest Microsoft solutions you may notice that a lot of what GUI does is running some scripting behind the scenes. This is true for a long time with the SQL Server Management studio where pretty much for any action you can generate a script that will let you automate a common task.

Similarly but the other way around, with the PowerShell Console for Sitecore, you can attach scripts to the context menu in your item tree.
