Turn recurring events into individual entries

[sdyang1729]

I became quite surprised to find out that org mode does not provide a way to write events which occurr periodically between start and end dates, such as <2025-11-29 Sat 10:00 +1w>--<2025-12-31>. Since my knowledge on elisp is not good enough to resolve it myself, I asked an AI whether he/she/it(?) can make a function which expands, for example, <2025-11-29 Sat 10:00 +1w>--<2025-12-31> as a series of single events, and he/she/it(?) did. I posted that function in my public repository, hoping that it may be of some help to someone. My address is https://github.com/sdyang1729/org-expand-periodic-events.
