enum exported from external module ("declare module" + "export enum") doesn't generate any javascript

[atsu85]

Hi,
I'm having problems with enums defined inside external module (i'm compiling to amd module format).
When using internal module format

module someModule {
    export enum Color {Red, Green, Blue};
}

then resulting JS contains enum and constants as expected (see http://www.typescriptlang.org/Playground#src=module%20someModule%20{%0A%20%20%20%20export%20enum%20Color%20{Red%2C%20Green%2C%20Blue}%3B%0A}%0A ).

But when using following syntax:

declare module 'someModule' {
    export enum Color {Red, Green, Blue}
}

then resulting JS file is empty (see http://www.typescriptlang.org/Playground#src=declare%20module%20someModule%20{%0A%20%20%20%20export%20enum%20Color%20{Red%2C%20Green%2C%20Blue}%0A}%0A )

Is this a bug or am i doing smth wrong? I don't see any compiler errors so I'd guess that this could be a bug.

I'm using TypeScript 1.5 beta with amd module format.

declare creates an "ambient" module -- it's for describing an existing object that isn't part of your compilation. For example, in node.d.ts we have declare module "fs" { to define the shape of the module fs.

If you want to have an external module with that content, make a file someModule.ts with the top-level declaration export enum Color { /*...*/ }
