"Smart names" in the error message #1

Closed bartoszlenar closed 4 years ago

bartoszlenar commented 4 years ago

Feature description

More human-friendly paths/names argument in the messages.
This is pretty much a copy cat of FluentValidation feature.
We already have {_name} message argument, maybe create a parameter like {_name|format=friendly} ?
SuperValue name would be Super Value..

Feature in action

Specification<decimal> specification = s => s
    .Positive()
    .WithPath("Number.Primary.SuperValue")
    .WithMessage("The {_name|format=friendly} needs to be positive!");

var validator = Validator.Factory.Create(specification);

var result = validator.Validate(-1);

result.ToString();
// Number.Primary.SuperValue: The Super Value needs to be positive!

Feature details

Extra parameter in Name argument?
Extra method in PathHelper that does the smart path resolving?
