| Instead of adding every program's directory to my system PATH, I prefer having | |
| a single directory on my PATH which contains Windows shortcuts (lnk files) | |
| pointing to each program. | |
| Windows lnks are different from softlinks because they maintain the program's | |
| real directory necessary for loading nearby dlls etc. | |
| However, this breaks `shutil.which` --> `subprocess.run` because subprocess.run | |
| with shell=False does not interpret lnks, and needs a direct path to the exe. | |
| So, this module provides a function `which` that if it finds an lnk file, will | |
| return the exe path, otherwise behaves the same as normal shutil which. | |
| ''' | |
| import os | |
| import shutil | |
| try: | |
| import winshell | |
| except ImportError: | |
| winshell = None | |
| def which(cmd, *args, **kwargs): | |
| path = shutil.which(cmd, *args, **kwargs) | |
| if path is None: | |
| return None | |
| if os.name == 'nt' and winshell and path.lower().endswith('.lnk'): | |
| path = winshell.Shortcut(path).path | |
| return path |
