[This segment mostly revolves around a discussion of PoshCode.org, the script repository for PowerShell which aims to match CPAN or PEAR in scope. After an introduction to PoshCode and an update on the site activity, we launch into a discussion of the future of the tool.]

PoshCode Requirements List

The "use" requirements

  1. Host snippets of code
  2. Host scripts with multiple functions (including a way to search on verb/noun which will find all the functions in a script)
  3. Host script modules -- which may contain multiple files (need ui for multiple files, and download for "all at once")
  4. Easy in, easy out. (low barrier to entry to contribute, multiple ways to download, view, browse, sort, filter)
  5. Compiled Modules would require source code to be uploaded and PoshCode online would compile
    • I don't think we want to get into compiling things on the server ... let them compile them themselves (we'd have to require *proj files after all) (Joel)
    • I'm not actually sure we want to do this at all, it's a deep overlap with every other source control service ...
    • This may be v2 stuff (hal)
  6. Users would be able to select from a list of approved licenses to be applied to their scripts.
    • License information would be prepended into script upon download
    • licenses:
      • CC-By (Attribution)
      • CC-PD (Public Domain)
      • GPL (sucks [says Hal])
      • MS-PL
  7. Repository would have the following fields: Description, Usage, PSVersion,  and Version History
    • Fields would be inserted as comments into the scripts when retrieved.
    • Dependency on other scripts would be controlled by a link to the other script(s).
    • Tags would be used to signify requirements on external dependencies. ex. "VMWare ESX 3.5", "AD 2003", etc.
    • Well we do need a version field for specifing PS version.
      • We should ask that users be explicit about versions by using the #requires -version n.n header in their scripts/modules. (oisin)
    • Comments
  8. Published WCF interface for external use.
  9. Repository would designed so that users can host their own repositories.
  10. RSS fallback


  • Installing DotNetNuke with PowerShell - "I started building a series of PowerShell scripts for simplifying the process. Although there are installers available for DotNetNuke, they are often out of date and are fairly rigid in how they perform the install. Using PowerShell provides a lot of advantages over a traditional installation program. I have complete control over the installation in an interactive environment and can change any one of dozens of parameters that control the installation."
  • PowerShell Team Blog : V2 Interview: Universal Code Execution Model - "At TechEd, I did an interview with Kevin Remde where I discussed the V2 Universal Code Execution model in detail. You can see it at: Universal Code Execution Model (UCEM)—a vision of how PowerShell scripts can run anywhere, anytime in just the right semantics."
  • Dmitry posted about a SQL Reporting Services PowerPack for PowerGui



Winners for the /n software Netcmdlets contest are:

  1. Steve Hiner - Wrote a wrapper for Send-Email script to send email using Gmail's SMTP server
  2. Mark Schill - Sent in two entries, the one we've chosen to highlight is his Twitter IM client bot thingy. It uses Send-IM and Get-Http
  3. Quintus - A script to download an ESPN podcast using the Get-Rss cmdlet

We will be posting the scripts over the next week, so watch the site for those.


  • Downgrading from PS v2 to v1 causes the snapins installed from v2 to quit functioning--even if they are compatible with v1.  A reinstall of the snapin will fix.
