Hello emms devs! I've been digging into the application and hope to contribute to it a bit in the future. Specifically I'm trying to figure out the a good way of editing tags on .opus files, and perhaps using the cache db for additional metadata storage.
Unfortunately, I had an unexpected Emacs crash this morning, and discovered on relaunching that my emms cache had lost information. After looking through the code, it appears that the cache is only saved when you ask it to be or if you kill Emacs. Normally, this might not be a huge deal. Most track data is actually metadata on the media files. I could just re-add them. However, in this case I'd only recently discovered that the tags i'd authored for some .opus files had not actually been saved. This set me off on finding out why the tag editor had "silently failed" to save the metadata to the file, while revealing the feature that the emms-cache-db could preserve metadata not attached to the file! similarly, i'd been experimenting with the emms-bookmarks.el which also uses the cache to store timestamps on a track. Anyhow, i was wondering if there might be some way to mitigate this problem in the future that doesn't demand manually saving the cache or killing Emacs? If anyone has some thoughts, I'd be glad to hear them :) Thank you, grant
