compilerOptions.declaration=true in tsconfig.json with output.path in webpack.config.js incorrectly nests *.d.ts file

[astralarya]

Setting compilerOptions.declaration=true in tsconfig.json with output.path defined in webpack.config.js incorrectly nests resulting *.d.ts file within output path.

Minimal example
ts-loader-declarations-bug.zip

package.json

{
  "name": "ts-loader-declarations-bug",
  "version": "1.0.0",
  "description": "Minimal example of ts-loader declarations bug",
  "main": "dist/output.js",
  "scripts": {
    "prepublish": "webpack",
    "test": "webpack"
  },
  "author": "Mara Kim",
  "license": "ISC",
  "devDependencies": {
    "ts-loader": "^0.8.2",
    "typescript": "^1.8.10",
    "webpack": "^1.13.1"
  }
}

tsconfig.json

{
    "compilerOptions": {
        "declaration": true
    }
}

webpack.config.js

module.exports = {
    entry: './input.ts',
    output: {
        path: __dirname + '/dist',
        filename: 'output.js',
    },
    module: {
        loaders: [
            {
                test: /\.ts$/,
                loader: "ts-loader",
            },
        ],
    },
};

input.ts

export default class {
    foo():number {
        return 42;
    }
}

To build:

npm install

Current output

Try ls -R dist to view the output directory. The output files are output.js and a weirdly nested *.d.ts file whose location can be described as follows:

If the global location of the ts-loader-declarations-bug directory is $PACKAGE, the *.d.ts file is located at $PACKAGE/dist/$PACKAGE/input.d.ts.

Expected output

The *.d.ts file should be located at $PACKAGE/dist/input.d.ts.

Miscellaneous

There is also currently no way to change the name of the resulting *.d.ts file.

Environment

• ts-loader: 0.8.2
• typescript: 1.8.10
• webpack: 1.13.1
• node: 6.2.2
• Operating System: Mac OSX 10.11.5

Think this is resolved with 0.9.1
