A few months ago, I wrote only a short note about the (at that time) upcoming release of the PowerShell module ISESteroids. More precisely, ISESteroids is an Add-On for PowerShell ISE by PowerShell MVP Tobias Weltner. This time I’ll highlight some randomly chosen features.

First start

Ok, that is not really a feature. You can start ISESteroids by entering Start-Steroids. Owing to the Module Auto-Loading feature, this will load the ISESteroids module. But, mind the “sensitivity” of Module Auto-Loading! It already loads a module behind the scenes as soon as you “touch” it with Get-Command, Get-Help and Tab Expansion. So be prepared that ISESteroids loads when you invoke commands like Get-Command -Module ISESteroids, Get-Help Start-Steroids, and such…

Expert Level

In a nutshell, ISESteroids‘ objective is to assist you in writing better PowerShell code more quickly. As ISESteroids is so packed with features, however, it could twist that aim right around and tend to confuse especially beginners. If you start ISESteroids for the first time it will ask for the Expert Level. Whatever you’ll choose there, you can it later set to a more appropriate level by choosing the corresponding option the “Expert Level” menu.

Snippets

Yes, the concept of code snippets is already included in ISE. It’s a bit halfhearted, though. ISESteroids uses ISE’s snippet mechanism to the advantage it deserves. If you press the default snippet key sequence STRG-J ISESteroids opens the snippet selector. First surprise: The snippets are organized in folders. Selecting a folder leads to corresponding code snippets. (Btw, with the backspace key you move up in the folder structure.) Second suprise: The snippet selector allows for adding new folders and new snippets.

Compatibility

If you deal with the latest PowerShell version only, be happy in your bubble. My field experience differs regarding the PowerShell versions my scripts have to support. PowerShell 1.0 really faded away meanwhile, but I still stumble over version 2.0 for example. ISESteroids helps you to handle or rather to prevent compatibility issues by marking code that isn’t compatible to the targeted PowerShell version. So, be sure to check the appropriate option in the “Compatibility” menu. Apart from version-related compatibility ISESteroids can mark commands that are not shipping with PowerShell default, thus you have a sort of visual reminder of your script/code requirements.

Risk Management

While you’re scripting, ISESteroids by default checks/analyzes your code against pre-defined risks. On potential risk detection you’ll be notified without attracting attention meaning that ISESteroids will change the risk status indicator from green to yellow or red. Keep an eye on that indicator. You’ll find it in ISE’s status bar and you can click it to enable/disalbe Autochecking, to approve the script, etc. Furthermore, there’s an option to manage black/white lists. (Note that the trail version doesn’t allow you to edit the pre-defined rules.)

ScriptMap

Starting from say 100 lines of code you find yourself scrolling more and more. If you deal with rather huge scripts on a regular basis you’ll definitely like ISESteroids‘ ScriptMap feature. Turned on, it will show a preview of the entire script. If you move the mouse pointer over that ScriptMap area it will act as a reading-glass that helps you to identify the code region in question. A single click will navigate to the chosen code region.

Navigating to function definition/references back and forth

Apart from ScriptMap ISESteroids has more help to offer regarding navigation within (huge) script files. Above the definition of a function ISESteroids displays the number of references to this function (within the same file).

Clicking on this information will navigate to the references:
ise2-functionreferences

If you want to navigate (back) to the function definition, right-click on the reference to function in question on choose “Go To Definition”:
ise2-functiondefinition

CloneView and split screen

Again, if you regularly deal with larger scripts ISESteroids helps you to minimize the ongoing efforts to navigate back and forth in the code. CloneView displays the current editor in a detached external window. Just right-click anywhere within the editor you want to clone and choose “Open CloneView”. The split screen feature divides the current editor in two sections, thus you’re able to simultaneously view/work on different sections of a single script.

Navigation Bar

OMG, yet another about navigating huge scripts? Yes and far more than that. If you turn on the Navigation Bar, at first sight you can both search text and instantly navigate to any function within the loaded script by selecting a function from the list.

Beyond that, the Navigation Bar…

  • offers access to a couple of snippets and templates,
  • enables you to create a function from selected code,
  • and enables you to export a selected function to a new/existing PowerShell module

File Version History

To come to an end, ISESteroids has a rather casual file versioning feature. For those who care about version control but don’t want to get worked up over git, svn, csv, tfs, etc. ISESteroids can keep a file version history for a given file. (Behind the scenes it maintains a zip archive with all the past major and minor versions.)
