Suggestion: provide default Validator implementation about promptly-dotnet HOT 2 CLOSED

Great suggestion. I'll be working on common sense defaults this week, including this one. I'll reply when it's in so you can check it out.

from promptly-dotnet.

I've added TextPrompt and IntPrompt to 0.0.6.12 to provide examples of what built in prompts for specific types will look like.

Each of these come with a default Validator that returns the text of the message if supplied, or Int from the message if it can be parsed, respectively.

For example:

                namePrompt.Set
                    .OnPrompt("What is your name?")
                    .OnSuccess((turn, value) =>
                    {
                        ClearActiveTopic();

                        State.Name = value;
                        // Returns a Task, should be returned so OnTurn that called it can return that.
                        OnTurn(turn);
                    });

See the SimplePrompt sample.

I can't supply a default Validator for Prompt<T> because I can't assume that I can parse the resulting value for OnSuccess. For example, if the prompt was defined as Prompt<T>, I can't supply a Validator that will work for all types of T.

I think this addresses your feedback/issue. If not, please reopen and we'll discuss.
