Typelite: Why is Dictionary mapped to KeyValuePair and not to any or [index:string]:any

Question

I have a class,

public class Instance : IResource
{
   public Dictionary Value { get; set; }

and it is mapped to

<

Answer 1

Here's a more generalized (and updated) solution that builds off of Markus Jarderot's answer:

static void RegisterDictionaryMemberFormatter(this TsGenerator tsGenerator)
{
    tsGenerator.SetMemberTypeFormatter((tsProperty, memberTypeName) => {
        var dictionaryInterface =
            tsProperty.PropertyType.Type.GetInterface(typeof(IDictionary<,>).Name) ??
            tsProperty.PropertyType.Type.GetInterface(typeof(IDictionary).Name);

        if (dictionaryInterface != null)
        {
            return tsGenerator.GetFullyQualifiedTypeName(new TsClass(dictionaryInterface));
        }
        else
        {
            return tsGenerator.DefaultMemberTypeFormatter(tsProperty, memberTypeName);
        }
    });
}

// and if you like the fluent syntax...
static TypeScriptFluent WithDictionaryMemberFormatter(this TypeScriptFluent typeScriptFluent)
{
    typeScriptFluent.ScriptGenerator.RegisterDictionaryMemberFormatter();
    return typeScriptFluent;
}

Use it like this:

var ts = TypeLite.TypeScript.Definitions().For(typeof(SomeClass).Assembly);
ts.ScriptGenerator.RegisterDictionaryMemberFormatter();

// alternatively with fluent syntax:

var ts = TypeLite.TypeScript.Definitions()
    .For(typeof(SomeClass).Assembly)
    .WithDictionaryMemberFormatter();

N.B. this only fixes type signatures of properties (or fields) that have dictionary types. Also definitions for IDictionary are not automatically emitted, you'd have to add them manually:

declare module System.Collections.Generic {
    interface IDictionary {
        [key: string]: TValue;
    }
}
declare module System.Collections {
    interface IDictionary {
        [key: string]: any;
    }
}
