Context constructor

Context({Style style, String current })

Creates a new path context for the given style and current directory.

If style is omitted, it uses the host operating system's path style. If only current is omitted, it defaults ".". If both style and current are omitted, current defaults to the real current working directory.

On the browser, style defaults to Style.url and current defaults to the current URL.

Implementation 

factory Context({Style style, String current}) {
  if (current == null) {
    if (style == null) {
      current = p.current;
    } else {
      current = ".";
    }
  }

  if (style == null) {
    style = Style.platform;
  } else if (style is! InternalStyle) {
    throw new ArgumentError("Only styles defined by the path package are "
        "allowed.");
  }

  return new Context._(style as InternalStyle, current);
}
