Bug Report

• TSLint version: 4.0.0
• TypeScript version: 2.1.4

TypeScript code being linted

const str = `
    here is some text


`;

with tslint.json configuration:

"rules": {
    "no-consecutive-blank-lines": [
        true
    ]
}

Treats the consecutive blank lines inside the string as a violation

Is there any alternatives to getTokenAtPosition function?
There is easy fix with

const token = (ts as any).getTokenAtPosition(node, start) as ts.Node;

but it is not a part of public API (however ts as any already used in noInferredEmptyObjectTypeRule.ts#L55 )

I tried to use LanguageService but none of methods that has AtPosition returns needed info.

the ts as any was only used there to handle backcompat with TypeScript v2.0, since the field doesn't exist in Typescript v2.1.

Seems strange that getTokenAtPosition is not public. I don't think we should be using private functions. I guess the alternative would be to walk every node to find the template string nodes, then filter the errors

I have a fix in my local fork. Will prepare a PR tomorrow(ish)
