Hi all, Yesterday I tweaked my Emacs configuration to use "ido-completing-read" to select the right address in the minibuffer, and noticed what seems a glitch in the related code. To accomplish the goal, I implemented my own selection function (defun esk-notmuch-address-selection-function (prompt addresses first) "Use `ido-completing-read' to select one of the addresses." (ido-completing-read prompt (cons first addresses) nil nil nil 'notmuch-address-history)) and then assigned it to `notmuch-address-selection-function': (setq notmuch-address-selection-function 'esk-notmuch-address-selection-function) As you can see, I had to `cons' the two arguments, because the caller of that function does something similar to the following (where `orig' is the text entered before TAB-completion): (options (notmuch-address-options orig)) (num-options (length options)) (chosen (funcall notmuch-address-selection-function (format "Address (%s matches): " num-options) (cdr options) (car options))) and the standard `notmuch-address-selection-function' is defined like: (defun notmuch-address-selection-function (prompt collection initial-input) "Call (`completing-read' PROMPT COLLECTION nil nil INITIAL-INPUT 'notmuch-address-history)" (completing-read prompt collection nil nil initial-input 'notmuch-address-history)) where that `initial-input' is not what I initially thought, the text entered by the user, but rather the first completion candidate. Wouldn't it be more "correct" to pass the unchanged `options' list and the "real" `orig' text as `initial-input' to the customizable function instead? I understand that it may be undesiderable to break existing configurations by rectifying the arguments in that way, and in such case could we change the `initial-input' argument name to better reflect the fact that it actually contains one possible candidate instead? Thanks in advance for any clarification, ciao, lele. -- nickname: Lele Gaifax | Quando vivrò di quello che ho pensato ieri real: Emanuele Gaifas | comincerò ad aver paura di chi mi copia. lele@metapensiero.it | -- Fortunato Depero, 1929.
