File system representation in a data structure

[Alfalfa]

I could get it to work by first copying the folder structure, then inserting each files in the proper nest. The result is a dict, which is then converted into a QMenu/QAction structure with a resursive fonction. All items are stored in a set to survive the garbage collection.

# First loop:
{'collision': {}, 'sub1': {'sub2': {'collision': {}}}}

# Second loop:
{'collision': {'collision': '/home/user/.config/qtpad-vim/notes/collision/collision.txt'}, 'sub1': {'sub2': {'collision': {'action3': '/home/user/.config/qtpad-vim/notes/sub1/sub2/collision/action3.txt'}, 'action2': '/home/user/.config/qtpad-vim/notes/sub1/sub2/action2.txt'}, 'action1': '/home/user/.config/qtpad-vim/notes/sub1/action1.txt'}, 'lvl0 with spaces': '/home/user/.config/qtpad-vim/notes/lvl0 with spaces.txt'}

    def _fill(self, current, dest):
        for part in current:
            if type(current[part]) is dict:
                item = QtWidgets.QMenu(part)
                dest.addMenu(item)
                self._fill(current=current[part], dest=item)
            else:
                item = QtWidgets.QAction(part, checkable=True)
                item.triggered.connect(lambda checked, path=current[part]: print(path))
                dest.addAction(item)
            self.items.add(item)

    def refresh(self):
        folder = Path(CFG_DIR / "notes")
        dirs = [x for x in folder.rglob("*") if x.is_dir()]
        files = [x for x in folder.rglob("*.txt") if x.is_file()]
        struct = {}

        for path in dirs:
            folders = path.relative_to(CFG_DIR / "notes")
            folders = PurePath(folders).parts
            last = struct
            for f in folders:
                last.setdefault(f, {})
                last = last[f]

        for path in files:
            folders = path.relative_to(CFG_DIR / "notes")
            folders = PurePath(folders).parts[:-1]
            last = struct
            for f in folders:
                last = last[f]
            last[path.stem] = str(path)

        self.clear()
        self.items = set()
        self._fill(struct, dest=self)

If someone think of a better way I would still like to know :)
