How to access an interface from a typescript.d.ts file when the module names conflict?

Question

How can I access the i1 from within esri.dijit?

module dijit {
    interface i1 {};
}

module esri {
    module dijit {
        interface i2 {}
        interface i3 extends dijit.i2, dijit.i1 {}
    }
}

See Playground example.

Two things. First you need to export an interface for it to be usable outside the module so:

module dijit {
    export interface i1 {};
}

Secondly if you are going to use the same name locally the global name dijit is going to be shadowed. So you need to create an alias :

module dijit {
    export interface i1 {};
}
import alias = dijit;

Now your complete code:

module dijit {
    export interface i1 {};
}
import alias = dijit;

module esri {   
    module dijit {
        export interface i2 {}
        interface i3 extends dijit.i2, alias.i1 {}
    }
}
