Source maps break

[jnicholl]

So far working with inject-loader has been great, but I found that source maps don't produce the right line numbers for injected modules. I'm running ES6 code through babel and using inject-loader to mock out dependencies for testing.
I was able to get something working by joining lines with spaces instead of \n and just passing the provided source map (second argument) back in this.callback. This isn't really right - the source map really needs a transform applied?

module.exports = function inject(src, sourceMap) {
  this.cacheable && this.cacheable();
  var regex = createRequireStringRegex(loaderUtils.parseQuery(this.query));

  var lines = [
    'module.exports = function inject(injections) {',
    'var module = {exports: {}};',
    'var exports = module.exports;',
    src.replace(regex, "(injections[$1] || $&)"),
    'return module.exports;',
    '}'
  ];

  if (sourceMap) {
    this.callback(null, lines.join(" "), sourceMap);
  } else {
    return lines.join("\n");
  }
}

Hey @jnicholl Thanks for the report. This is the same issue as #10, so if you don’t mind I’ll close this in favour of that earlier issue.

Works for me. Sorry, I read through that issue but didn't quite realize it was the same.
