Function parse_requirements

goex/exec_engine/container_utils/code_parser.py:250–300

Parse a requirements formatted file. Traverse a string until a delimiter is detected, then split at said delimiter, get module name by element index, create a dict consisting of module:version, and add dict to list of parsed modules. Args: file_: File to parse. Raises:

(file_)
