Binary powershell module command formatting

Question

I'm writing a binary powershell module that will replace another command line tool that just outputs text.

I have a handful of commands that follow the powershell verb guide (eg. Add-MyModuleUser -UserName "My Username") but I would like to also have an overloaded command that takes the object responses of these and format them like the tool I'm replacing which accepts input in the following format:

myModule addUserName "My Username"

My instinct says to have a command called Invoke-MyModule with an alias to myModule, so I could call Invoke-MyModule addUserName "My Username" which would call Add-MyModuleUser and format that output with like the original tool.

Question: How can I get a powershell command to accept input like this?

Note: I was reading about ParameterSets which seem promising, I was thinking I could declare the parameter set to string, so the first word in the string sets the ParameterSet for the rest of the parameters that are entered.

Thanks!

If the remaining parameters are based on the value of a parameter rather than the presence of a parameter, you probably need to use "Dynamic Parameters". See "get-help about_functions_advanced_parameters", and the dynamic parameter content is towards the end.

Parametersets would be fine if you used a series of switch parameters (-AddUserName, for example) rather than the value "addUserName". ParameterSets are chosen by the presence of parameters that are exclusive to a particular set.
