Is there a PowerShell code formatter / pretty printer? [closed]

Question

I'm looking for a source code beautifyer for PowerShell programs. Ideally, it would be CLI based, but any solution is acceptable. I would like to avoid configuring a generic pretty printer tool; I'd like a solution that works for PowerShell out of the box. Is there such a thing?

UPDATE: it's now on GitHub: https://github.com/DTW-DanWard/PowerShell-Beautifier

I wrote a PowerShell pretty printer / code cleaner in PowerShell. It cleans white space, indents code groups, replaces aliases with commands, fixes casing on commands, parameters, types, etc. You can use it to reformat a file in place or read a source file and output the result in a different file.

Let me know what you'd like to see changed/configurable/etc.

Answer 2

I don't know of any. However, PowerShell V2 exposes a PowerShell tokenizer you could build on: System.Management.Automation.PsParser

It might be interesting to do some "lint"-like checks, too.

For example, I think scripts should avoid using aliases that aren't marked ReadOnly, as users may have changed them. See Where are the default aliases defined in powershell? for some discussion.
