Define inputs in reusable objects

[stuartmcgillivray]

Expanding ActivtyInput functionality to allow classes to be used for re-usable input properties across activities.

Overview

ActivityInputObjectAttribute

The ActivityInputObjectAttribute identifies a class to extract ActivityInputs from.

A category can be provided on the ActivityInputObjectAttribute that will be added to all of the properties in that class that don't provide their own category.

        [ActivityInputObject(Category ="Example Category")]
        public ExtraProperties Example { get; set; }

Designer

The properties will appear in the designer form as if they were added directly to the activity.

Examples

Setting Category with ActivityInputObjectAttribute

    public class ExtraProperties
    {
        [ActivityInput(Hint = "The base URL.",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public string BaseUrl { get; set; }

        [ActivityInput(Hint = "The REST Port.",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public int? RestPort { get; set; }

        [ActivityInput(Hint = "The Grant Type to authenticate.",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public string GrantType { get; set; }

        [ActivityInput(Hint = "The Username to authenticate.",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public string RestUsername { get; set; }

        [ActivityInput(Hint = "The Password to authenticate",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public string RestPassword { get; set; }
    }

    public class ExampleActivity : Activity
    {

        [ActivityInputObject(Category = "Example Category")]
        public ExtraProperties Example { get; set; }

        [ActivityInput(Hint = "The text to write.", SupportedSyntaxes = new[] { SyntaxNames.JavaScript, SyntaxNames.Liquid })]
        public string? Text { get; set; }

        private readonly TextWriter _output;

        protected override async ValueTask<IActivityExecutionResult> OnExecuteAsync(ActivityExecutionContext context)
        {
            return Done();
        }
    }

Overwrite ActivityInputObjectAttribute Category

public class ExtraProperties
{
        [ActivityInput(Category = "Rest Configuration",
            Hint = "The base URL.",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public string BaseUrl { get; set; }

        [ActivityInput(Category = "Rest Configuration",
            Hint = "The REST Port.",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public int? RestPort { get; set; }

        [ActivityInput(Category = "Rest Configuration",
            Hint = "The Grant Type to authenticate.",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public string GrantType { get; set; }

        [ActivityInput(Category = "Rest Configuration",
            Hint = "The Username to authenticate.",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public string RestUsername { get; set; }

        [ActivityInput(Category = "Rest Configuration",
            Hint = "The Password to authenticate",
            UIHint = ActivityInputUIHints.SingleLine,
            SupportedSyntaxes = new[] { SyntaxNames.Literal, SyntaxNames.Liquid, SyntaxNames.JavaScript })]
        public string RestPassword { get; set; }
}

public class ExampleActivity : Activity
{

        [ActivityInputObject(Category ="Example Category")]
        public ExtraProperties Example { get; set; }

        [ActivityInput(Hint = "The text to write.", SupportedSyntaxes = new[] { SyntaxNames.JavaScript, SyntaxNames.Liquid })]
        public string? Text { get; set; }

        protected override async ValueTask<IActivityExecutionResult> OnExecuteAsync(ActivityExecutionContext context)
        {
            return Done();
        }
}

That is awesome!
