They do this: (advice-add #'completion-metadata-get :before-until #'marginalia--completion-metadata-get) Looks like this is how they install their annotation-function. > Anyway, I've played a bit with responding to metadata requests and it > looks like it's not really suited for my goal because it seems to assume > that the metadata won't change (e.g., category from buffer to file) > during a single completion which is obviously a reasonable assumption. Hmm, yes, that's a problem. Seems a completion table can only provide one ind of metadata for all completions and what you want doesn't fit at all into that approach. See the comment in `completion-table-in-turn'. Michael.
