The module loader will be asked for the source only when getlines is called, not immediately. If there is an entry in the cache already, it is not altered. :return: True if a lazy load is registered in the cache, otherwise False. To register such a load a module loader with a get_source method must be found, the filename must be a cachable filename, and the filename must not be already cached. r TFr r � __loader__�__name__� get_sourceN)r r r& r' �get�getattr� functools�partial)r r �name�loaderr: � get_linesr r r r( � s % r( ) �__doc__r= r- r r1 �__all__r r r r r r r( r r r r �<module> s A
