When you pass a function to completing-read, it is not used to generate the list of canidate completions. As documented: collection can be a list of strings, an alist, an obarray or a hash table. collection can also be a function to do the completion itself. predicate limits completion to a subset of collection. See `try-completion' and `all-completions' for more details ... collection can also be a function to do the completion itself. It receives three arguments: the values string, predicate and nil. I think what you want is: (defun matt/external-addressbook-completion (stub) (interactive (list (completing-read "Name: " (edsquery-return-addresslist "") nil t)))) -- Kevin Rodgers Denver, Colorado, USA ^ permalink raw reply [flat|nested] 8+ messages in thread

Dunno. Your function that does all of the completion, `edsquery-return-addresslist' isn't shown. The error message is saying that function `ad-Orig-minibuffer-complete' expected a number or a marker but received the list of strings. You also apparently advised the standard function `minibuffer-complete', and that code isn't shown either. So it's difficult to guess what is the problem. > i'm not sure, but it looks like it isn't breaking the cdr > cell down into its components before evaluating it? > suggesting to me that, again, there's something wrong with my syntax. No comprendo. What isn't breaking what cdr cell down into what components? FWIW, I see nothing wrong with the call to completing-read. The problem is likely in your completion function `edsquery-return-addresslist'. > i appreciate the remedial lisp lessons. sorry to just continue not > getting it... thanks again, The error message should help. Look at your advised version of `minibuffer-complete', `ad-Orig-minibuffer-complete', and see why and where it expects a number or marker. Look at why your function `eds...' gives it a list of strings in that place instead.

No. As Kevin mentioned, and as I explained prior to that, if you use a function as the COLLECTION argument, then `completing-read' expects that function to do _everything_. It does _not_ expect that function to just return a list of possible completion candidates, which it then uses to perform completion. It expects that COLLECTION function to perform the completion itself. `completing-read' doesn't really do much at all in that case - it simply prompts and then passes your function to `try-completion', which in turn uses your function to perform completion. It's up to your function to perform the completion you want, that is, to do _everything_. This is all documented in the doc strings of `completing-read' and `try-completion', and in the Elisp manual's nodes `Minibuffer Completion' and (especially) `Programmed Completion'. You really must read that if you want to learn this. I'm not sure you need programmed completion for what you want to do - I doubt it, in fact. But if you do, then you need to read the manual about that topic. > > The error message is saying that function > > `ad-Orig-minibuffer-complete' expected > > a number or a marker but received the list of strings. > > i think ad-Orig-minibuffer-complete comes from the > minibuffer-complete-cycle package; i've taken out references to it in > my .emacs for now. but my issue persists. Always try to minimize the number of things in the big sack of unknowns you shake to test code. If your code doesn't rely upon stuff like `minibuffer-complete-cycle', then by all means get rid of it (for now). This is all the more true if such extraneous code advises functions. Advising functions makes debugging more difficult (IMO). You think you are trying to understand `minibuffer-complete', but really you are dealing with some modified (advised) version of it.

It would be quite difficult to understand this stuff if you didn't read up on it. That's what the manual is for - it's your friend. And it is usually much better at explaining things that we folks at help-gnu-emacs. People here are glad to help, but you need to do a minimum of homework yourself - to help yourself. > > The error message should help.

In that case, `completing-read' is not expecting the function to return a set of completion candidates; it is expecting it to perform completion - completely. ;-) > clearly i'm misunderstanding something but it's the kind of > conceptual error i have trouble finding an answer for in the > documentation. Study node `Programmed Completion' in the manual carefully. If you then have questions, post again here. But if you can produce the set of completion candidates you need, then you likely do not need to worry about programmed completion (i.e. a functional COLLECTION arg) - just provide the list of candidates. Programmed completion is for situations where you cannot do that - where, for instance, such a list depends on something contingent that only becomes available during the completion process itself. Bottom line: If you can give `completing-read' the list of candidates to use, do so. > thanks again. you should feel free to drop me, though, drew -- i > appreciate all your efforts. Don't sell yourself short. _IF_ you need programmed completion, then yes, it is a bit confusing, but node `Programmed Completion' is your friend. _IF_ you don't need it, that is, if you can come up with the list of completion candidates you need explicitly, then just do that. ^ permalink raw reply [flat|nested] 8+ messages in thread
