General PowerShell and Perl conventions for WFA

You must understand certain PowerShell and Perl conventions that are used in WFA to create scripts that are consistent with existing scripts.

  • Use variables that help to clarify what you want the script to do.

  • Write readable code that can be understood without comments.

  • Keep the scripts and commands as simple as possible.

  • For PowerShell scripts:

    • Use cmdlets whenever possible.

    • Invoke .NET code when there is no cmdlet available.

  • For Perl scripts:

    • Always end “die” statements with newline characters.

      In the absence of a newline character, the script line number is printed, which is not useful for debugging Perl commands executed by WFA.

    • In the “GetOpt” module, make the string arguments to a command mandatory.
