AutoSpectre Source Generation

This allows you to decorate a class with the AutoSpectreForm attribute and decorate properties on that class with:

• TextPromptAttribute
• SelectPromptAttribute

and void or Task methods with

• TaskStepAttribute

and behind the scenes a Form (SpectreFactory) will be generated to request input using Spectre.Console

Example

Code

[AutoSpectreForm] public class Example { [TextPrompt(Title = "Add item")] public int[] IntItems { get; set; } = Array.Empty<int>(); [TextPrompt(Title = "Enter first name", DefaultValueStyle = "bold")] public string? FirstName { get; set; } = "John Doe"; // Default value in prompt [TextPrompt(PromptStyle = "green bold")] public bool LeftHanded { get; set; } [TextPrompt(Title = "Choose your [red]value[/]" )] public SomeEnum Other { get; set; } [TextPrompt(Secret = true, Mask = '*')] public string? Password { get; set; } [TextPrompt] public OtherAutoSpectreFormClass ChildForm { get; set; } = new(); [TextPrompt] public IReadOnlyList<OtherAutoSpectreFormClass> Investors { get; set; } = new List<OtherAutoSpectreFormClass>(); [TaskStep(UseStatus = true, StatusText = "This will take a while", SpinnerType = SpinnerKnownTypes.Christmas, SpinnerStyle = "green on yellow")] public void DoSomething(IAnsiConsole console) { console.Write(new FigletText("A figlet text is needed")); } [SelectPrompt(WrapAround = true, PageSize = 3, MoreChoicesText = "Press down to see more choices", HighlightStyle = "purple")] //[SelectPrompt(Source = nameof(ItemSource))] public string Item { get; set; } = string.Empty; public List<string> ItemSource { get; } = new() { "Alpha", "Bravo", "Charlie" }; [SelectPrompt(InstructionsText = "Check the special items you want to select")] //[SelectPrompt(Converter = nameof(SpecialProjectionConverter))] public List<int> SpecialProjection { get; set; } = new(); public string SpecialProjectionConverter(int source) => $"Number {source}"; public List<int> SpecialProjectionSource { get; set; } = new() { 1, 2, 3, 4 }; [TextPrompt] // [TextPrompt(Validator = nameof(EnterYearValidator))] public int EnterYear { get; set; } public string? EnterYearValidator(int year) { return year <= DateTime.Now.Year ? null : "Year cannot be larger than current year"; } [TextPrompt] public HashSet<string> Names { get; set; } = new(StringComparer.OrdinalIgnoreCase); public string? NamesValidator(List<string> items, string newItem) { if (newItem == "Foobar") return "Cannot be Foobar"; if (items.Contains(newItem)) return $"{newItem} has already been added"; return null; } [TextPrompt] public bool AddExistingName { get; set; } [TextPrompt(Condition = nameof(AddExistingName))] public string?
