Argument parsing in function

[Hejsil]

There is clap.Result. It's the function that generates the return type for clap.parse.

@Hejsil could you provide an example usage in the above snippet? Simply putting it as clap.Result into the return type definition doesn't work. Do I have to use something like @Type(clap.Result)?

[Hejsil]

Something along the lines of this:

const params = ...;

pub fn parseAndValidateArgs() !clap.Result(clap.Help, params, clap.parsers.default) {
  const cliArgs = try clap.parse(clap.Help, params, clap.parsers.default);

  // validate here

  // then return
  return cliArgs;
}

It works, thank you.
