Description:
 def read_pattern(text_str, patterns, terminate_on_match=False, postprocess=str):
 """ General pattern reading on an input string Args: text_str (str):
 the input string to search for patterns patterns (dict):
 A dict of patterns, e.g., {"energy": r"energy\\(sigma->0\\)\\s+=\\s+([\\d\\-.]+)"}. terminate_on_match (bool):
 Whether to terminate when there is at least one match in each key in pattern. postprocess (callable):
 A post processing function to convert all matches. Defaults to str, i.e., no change. Renders accessible: Any attribute in patterns. For example, {"energy": r"energy\\(sigma->0\\)\\s+=\\s+([\\d\\-.]+)"} will set the results from regex and postprocess. Note that the returned values are lists of lists, because you can grep multiple items on one line. """
