SwifterSharp

Make C# more like Swift.

Summary

This project is a collection of C# code analyzers that make C# act more like Swift. Right now it's a collection of one.

Pull requests are welcome.

Why do this?

A coworker showed me in Swift you can require named arguments when calling a method. In C# these are optional except in a few circumstances.

This is a feature I wish C# had. There are some situations when I wish I could require callers to explicitly name all arguments, like to try to prevent transposed arguments or to make transposed arguments easier to identify. This project is my attempt to add this feature to C# and make it work more like Swift.

Maybe I'll add more features if I'm further proselytized.

Analyzers

ForceNamedArguments

If you add the attribute ForceNamedArguments to a method, then all callers will be forced to explicitly name all arguments when calling that method. By default not naming all arguments will result in a compiler error.

For example:

[ForceNamedArguments]
public static void Work(int x, int y, int z)
{
    // some work
}

Without all arguments named:

With all arguments named:

There's currently no code fix for this error in this package. Additionally, this attribute currently only targets methods. It could conceivably also target individual method parameters, selectively requiring some but not all arguments to be named.

Configuring Analyzers

Analyzer rule severity can be changed by right-clicking the analyzer in the solution explorer in Visual Studio. For example, to change the ForceNamedArguments analyzer from its default, an error, to a warning:

If you're not using Visual Studio, since you don't need to in today's cross-platform world, you can also add a ruleset to your project or solution and add entries to change SwifterSharp rule severities:

<Rules AnalyzerId="SwifterSharp.Analyzers" RuleNamespace="SwifterSharp.Analyzers">
  <Rule Id="SwifterSharp1000" Action="Warning" />
</Rules>
