If code is supplied, it will use a combination of the code and the filename to determine the best lexer to use. For example, if the file is ``index.html`` and the file contains Django templating syntax, then "html+django" will be returned. If the file is ``index.html``, and no templating language is used, the "html" lexer will be used. If no string of code is supplied, the lexer will be chosen based on the file extension.. Args: path (AnyStr): The path to the file containing the code you wish to know the lexer for. code (str, optional): Optional string of code that will be used as a fallback if no lexer is found for the supplied path.
