ConsoleInteractive is a netstandard2 library that make it easy to parse and
validate data from the console. It provide methods to request data in all basic
C# types, and allow to create new input types
When I create small command line tools I kept rewriting input parse and validation, and despite great tools to parse arguments and to print output, I didn't find anything that could help me do it.
You can install it using nuget:
dotnet add package ConsoleInteractive --version 2.0.1<PackageReference Include="ConsoleInteractive" Version="2.0.1" />Install-Package ConsoleInteractive -Version 2.0.1
Register default components:
ConsoleI.RegisterDefaults()
The easiest way to start using it is to clone the repo and see how the ConsoleInteractive.Demo is built, or by reading the Documentation
public class TestFormClass {
public const string REQUIRED = "TEXT_REQUIRED";
public const string AGE_INTERVAL = "AGE_INTERVAL";
public const string WORK_TITLES_COMPONENT = "WORK_TITLES_ENUM_COMPONENT";
public TestFormClass() {
/* For demo purposes validators and components are register at the constructor
In real world, would be better to do it at start up, or before the
first call */
// Validation for string
ValidatorProvider.Global.Register(REQUIRED, ValidatorCollection
.Create<string>().Add(s => (s.Length > 0, "Can't be empty")));
// Validation for uint
ValidatorProvider.Global.Register(AGE_INTERVAL, ValidatorCollection
.Create<uint>()
.Add(n => (n >= 13, "Age must be older than 13"))
.Add(n => (n <= 150, "Age must be younger then 150"))
);
// Register a custom component with name <WORK_TITLES_COMPONENT>
ComponentsProvider.Global.Register(WORK_TITLES_COMPONENT,
InputSelection.FromEnum<WorkTitles>());
}
[FormEntry(Priority = 0, Message = "Insert name", ValidatorsKey = REQUIRED)]
public string Name { get; set; }
[FormEntry(Priority = 1, Message = "Insert age", ValidatorsKey = AGE_INTERVAL)]
public uint Age { get; set; }
[FormEntry(Priority = 2, Message = "Select work", ProviderKey = WORK_TITLES_COMPONENT)]
public WorkTitles WorkTitle { get; set; } // Enum
public override string ToString() {
return $"{Name} ({Age}) => {string.Join(';', WorkTitle.ToString())}";
}
}TestFormClass data = await ConsoleI.RenderForm<TestFormClass>();
