isesteroids PSSharper would have to analyze your code and try and determine whether your code can accept null values. Note that in either case, you (the code author) would

still have to validate the user input to see if it makes sense,.e. Code composition as well as code formatting is governed by plenty of personal preferences, backgrounds, and priorities. If it was an Int, it is the value. How can you consent with writing set unions and intersection practice null values? So for the time being, we changed the rule in isesteroids and use an attribute. . True or eq, false will deliver the expected results. Jeffrey also explains why the unexpected results are returned as well. My client had written a script that attempted true / false evaluation using the eq comparison operator as though true and false evaluation where strings, and they were getting an unexpected results, getting a true match when a false was expected, and vice versa. Well, you could just assign null, mimicking what PowerShell does under the hood if there is no default value at all: param ( Path null, Filter null or: param ( StringPath StringFilter ' please keep in mind that this is an edge case. This way, the rule would read: If a parameter is optional, it should have a default value unless the code author has declared that a null value is acceptable. .

There is a simple rule that caused a lot of debate: A parameter should either be mandatory or have a defined default value. So the rule should really be: If a parameter is optional, it should have a default value unless a null value is acceptable. I posted an updated Powershell script for a client to resolve rule-generated alerts in scom 2007, but also to illustrate an example of true and false evaluation in Powershell.
