Unable to augment export = function/namespace

[blakeembrey]

Possible duplicate of #7148, but it seems like it should be working according to #6742.

TypeScript Version:

1.8.7

Code

File: 1.d.ts

declare module 'm1' {
  function x (): x.Test;

  namespace x {
    export interface Test {
      prop1: boolean;
    }
  }

  export = x;
}

File: 2.ts

/// <reference path="./1.d.ts" />

import m1 = require('m1');

declare module 'm1' {
  interface Test {
    prop2: boolean;
  }
}

m1().prop2 // `prop2` does not exist on type `Test`.

Expected behavior:

Interfaces should merge, giving me access to prop2.

Actual behavior:

No prop2 on interface Test.

I can repro this in 1.8 and it seems to be fixed in @next.

@vladima Thanks for the confirmation, will it be ported to 1.8?

i would use typesctipt@next for this one. there are a couple of other related fixes as well.

@Guria If you want to type moment plugins, looks like you'll need to be using typescript@next. (Ref: #7148 (comment)).

@blakeembrey thanks, will try it :)

Seems working. Thanks.
