Add code fix or formatting rule to generate splatted parameters from command invocation

[mpearon]

Sapien's PowerShell Studio has a feature that will allow you to convert single line commands to be splatted.

This would be a great enhancement, I think!

Yep, I think we could add this as a command in the editor. What do you think @kapilmb?

[kapilmb]

Or a code-action, perhaps?

Not sure about the timeline though. I would say this will be a great post-1.0 addition. What do you say?

[daviwil]

It could be a suggested code action if the line was longer than a certain length, for sure. However, I think it'd be nice if this was something that could be invoked anytime on a command in a script file.

We could try it post-1.0 unless @Jaykul gets to it first ;)

[Jaykul]

If there was a rule that gave a warning on lines longer than 120char, but an information on all commands with more than one parameter ... would that be enough to let you surface it the way you're imagining, @daviwil?

[daviwil]

Yeah, that could work. For the "invoke any time" approach, I think we'd basically just run the rule on the current script line (including any backticked lines following that) and see if a marker gets returned. If yes, apply the correction.
