Keeping a Continuous Total

There’s a function stored in my $PROFILE (CurrentUserAllHosts). Maybe you’ve read about it before; it’s come up. It’s purpose is to go out to the PowerShell Gallery and determine how many downloads I have of each PowerShell script and/or module I’ve published there. In the past, my tool provided a download total for each project along with a single total of all the downloads. Today that changes, but before it does (I seriously haven’t the updated code yet — typical), let’s show the code and results, as it currently stands.

See how we only have the single Total downloads above (the 1779 value)? I’ve decided I don’t like that, so it’s about to change. I want the total downloads as each of these objects is being returned (, calculated,) and written. In a recent article here at, I included an image of this default output: don’t mind the background color, however.

In the newest version of this little $PROFILE based function, the first thing I’ve done is added the [CmdletBinding] Attribute. It’s to add the OutVariable Common Parameter. We’ll see how that’s helpful momentarily. The second thing we’ve done is begun collecting and displaying, what I’ve called the Type (find in the below code: “; $Type = Module” or “Script”). This will differentiate, when added to each object, whether one of my projects in the PowerShell Gallery is a module or script. Here’s the updated code with these two additions. Notice also, the object created inside [PSCustomObject] now includes a Type property. This is where the “Module,” or “Script” determinations are included.

The other recent addition to this code is the addition of my TotalDownloads variable. Through each iteration we update it so it has the current value and then display said current value with the current object. I may have been a little too generous with my [int] casting; however, do remember that the plus sign (+) is also a concatenation operator. I want a total download count — not a string of individual download counts, strung together.

In closing, there’s something else to remember. By default (and there’s ways around this), when we have more than four properties being returned per object, the “table” output becomes a “list” output — have a look.

While using the newly added OutVariable is helpful if I want to display the above output and capture the output into a variable at the same time, here’s how I run this now.

Next up is likely putting this code into a background job; it’s not the quickest thing I’ve written (although I blame that on the speed of the PowerShell Gallery lookup process — not me). Perhaps a background job that runs in, or starts at, the end of the profile script. This, in order that these slow-to-obtain results are available sooner and with minimal impact.
