Module Contents
---------------






.. function:: merge_dicts(*dicts)

   
   Merge several mappings together; nested values are merged recursively.

   Operation is not commutative, each next dictionary overrides values of the previous one for
   the same keys sequence.
   (see example). Example:
   >>> a = {1: 1, 2: {3: 3, 4: 4}}
   >>> b = {1: 10, 2: {3: 30, 4: 4, 5: 5}}
   >>> merge_dicts(a, b)
   >>> {1: 10, 2: {3: 30, 4: 4, 5: 5}}
   >>> merge_dicts(b, a)
   >>> {1: 1, 2: {3: 3, 4: 4, 5: 5}}

   :return: New merged dictionary.

   









.. function:: load_jinja2_template(path:str)

   
   Return a loaded template by the specified file path.

   









.. function:: huge_progress_bar(sequence:Sequence, log:logging.Logger, get_iter_name:Callable)

   
   Create big multi-line progress bar with the logs.

   









.. function:: handle_input_arg(input_arg:Union[str, Iterable[str]], log:Optional[logging.Logger]=None)

   
   Process input arguments and return an iterator over input files.

   :param input_arg: list of files to process or `-` to get file paths from stdin.
   :param log: Logger if you want to log handling process.
   :return: An iterator over input files.
