In a script I have several functions that need to break down an SVN external definition. These can either be <url> <path>, -r<rev> <url> <path>, or -r <rev> <url> <path>, and the mechanics I came up with to extract the data is more than just two lines, so I want to put this into a separate function.
But when I do so, I end up with three variables containing the relevant data which are local to the function, and I see no way to get all three of them them to the caller.
In a proper programming language I would return a compound type containing all three values, but I don’t see how to do that in Powershell. Of course, I could split this into three separate functions, but then I am back at violating the DRY rule.
So what can I do here in Powershell?
You can return an array of
[string]and then let the caller split it or return a custom object and always the caller do the split.
