Be careful with path handling. You don't want to impose a given OS.
I recommend using the pathlib library instead.

Actually, forward slashes work under windows. I've only encountered a few arcane cases where they cause problems. See the pmg test suite. Runs on Windows in GHA and it's all forward slashes.

The ~ is not valid on Windows, although I guess you get out of that pickle by doing os.path.expanduser.

Doing os.path.expanduser(extraction_path) expands to 'C:\\Users\\asros/.cache/pymatgen/ddec' which will work with os.makedir since os is smart. So, tests will pass, but you're playing with fire a bit... 😅
Guess this is more personal preference because I'm a Windows user tired of opening PRs to fix paths, although it's indeed fine here after closer inspection.

Yeah, i'm running a live experiment. So far it's only caused issues 2 or 3 times and they were niche. Feel like so far the readability gain from not using os.path.join was well worth it. Need to reconsider if sth non-niche comes up.

Feel free to ignore these comments then @chiang-yuan. Good to know, @janosh.

Thanks @Andrew-S-Rosen . I actually prefer pathlib since it is a newer standard over os.path. I was just following what we already have in the code 😉 Will change it whenever appropriate :)

Seems it doesn't really matter :)

while pathlib has some nice features, i find it a bit too OOP with resulting perf overhead compared to os.path (see e.g. https://youtu.be/tFrh9hKMS6Y). although admittedly the speed diff doesn't matter in practice.

Same comments here regarding path handling. Do not hard-code slashes. There are more below. You get the idea.

@janosh I use monkeypatch to mock the class method directly (rather than through module namespace) and add |

@chiang-yuan thanks! i think there are a lot of unintended white space/indentation changes from trailing commas in this PR?

can you revert the trailing comma insertions in this file and tests/command_line/test_chargemol_caller.py? makes it hard to spot meaningful changes
