Console Prompts

A small .NET library to take user input in a console with some exception handling and fluent syntax.

Features

• User input queries with fluent syntax
• Input restrictions (e.g. numeric range, string length, path to an existing file)
• Invalid input handling
• Prompt styling
• Support for IParsable

Usage

Use the Prompt class to create a query with one of the For methods. Add limits to the query with fluent syntax and Display the query to the user.

int userAge = Prompt.For<int>("Your age").NoLessThan(1).Display();
const int drinkingAge = 21;

if (userAge >= drinkingAge)
{
	Console.WriteLine("You are of drinking age!");
}
else
{
	Console.WriteLine("Sorry, you can't have a drink.");
}

Styling

The way prompts are displayed can be changed with PromptStyler class.

PromptStyler.PromptFormat = "[{1}] {0} = ";
PromptStyler.InvalidInputFormat = "I can't accept that: {0}";
PromptStyler.HintLevel = PromptHintLevel.Verbose;

Console.WriteLine("f(x) = 60 + 10x");

float x = Prompt
	.For<float>("x")
	.ForceFinite()
	.OfRange(0, 1)
	.AddHint("real", PromptHintLevel.Verbose)
	.Display();

Console.WriteLine($"f(x) = 60 + 10 * {x} = {60 + 10 * x}");
