How can I view the minimal required arguments of a Wolfram Language function?
How can I view the minimal required arguments of a Wolfram Language function?
This question might be a bit of an overstretch, or really obvious, but I haven't been able to find an answer yet.
Is there a way to automatically view the minimum required arguments for a WL function? For example, Sin only requires 1 argument, while Replace requires both an expression and the list of rules. Is there a way that, for example, I can input Sin into a function, and get back something like Real, or enter Replace, and get back Expression, Rules?
Sin
Replace
Sin
Real
Replace
Expression, Rules
I hope this makes sense - I would like to be able to automate input to any function in Mathematica, by being given the required arguments.
Thanks!

Information[functionName]

That's a good idea, however, when I try val = Information[Replace], and then view the results with ?val, it returns that val = Null

Information has side effects and doesn't return anything. Fortunately we can scrape the side effects with Block[CellPrint = Sow, Reap[Information[Replace]][[-1, 1]]]. However Replace::usage would be an easier way to see the information your after.$endgroup$

Information
Block[CellPrint = Sow, Reap[Information[Replace]][[-1, 1]]]
Replace::usage

Great, thanks! I hadn't known that was possible

You can use SyntaxInformation:
SyntaxInformation
SyntaxInformation /@ Sin, Replace // Column

It works - thanks!!!
