My app allows users to enter powershell scripts that it will run for you later. Is there a straightforward way to be able to validate the powershell script without running it, so that when the user enters it the program could report syntax errors?
Thanks.
In PowerShell v2 you have tokenizer that can process script without running it. Look at class System.Management.Automation.PSParser and it’s static method Tokenize:

In v3 it’s gets even better, there is whole language namespace/ AST support:
