I'm not sure I understand your question, but if I do, have a look at function `call-interactively'. It lets you call an interactive function (command) in such a way that the function's `interactive' spec is used to obtain the argument values. See the Elisp manual, node `Interactive Call'. ^ permalink raw reply [flat|nested] 11+ messages in thread

Thanks for your reply. I do not want to interactive call a function but call it like pressing a key. for example, press tab in help-mode will cause forward-button function which has a parameter, however I do not need give it parameter and it get parameter by itself. my aim is to binding a funtion to tab key in every mode: if cursor is at the end of word then call M-TAB's function, else call TAB's function. (defun my-indent-or-complete () "if cursor is at the end of word then call M-TAB's function, else call TAB's function." (interactive) ;; ^C^t is binding to tab key's function in mode-hook. (let ((TAB-func (key-binding "^C^t")) (M-TAB-func (key-binding "\M-\t")) ) (if (looking-at "\\>") (apply M-TAB-func '()) (apply TAB-func '()) )) ) my way is only suitable for lisp-indent-line but not forward-button. ^ permalink raw reply [flat|nested] 11+ messages in thread

As you said, `forward-button' expects at least one argument, and you are applying it to zero arguments. Above, you say "it get parameter by itself". It's unclear to me what you mean by that. Calling the command interactively (call-interactively #'button) will provide the needed arguments (by default, N=1, WRAP=(point), DISPLAY-MESSAGE=(point), which I think will do just what you want - but you say you don't want that. Again, perhaps someone else can help you better. Also, it sounds like you are trying to do something that several others have already done.

This, however, might not work. Because if you bind your function to tab, you might be unable to retrieve the original binding. regards, Nikolaj Schumacher ^ permalink raw reply [flat|nested] 11+ messages in thread

Thank you very much! No problem. I sympathize with the language difficulties. BTW, I've filed an Emacs bug (#1010) suggesting a slight change in the doc for `call-interactively', to try to prevent the confusion you had. `call-interactively' just provides the args needed by a command automatically, according to its `interactive' spec. In some cases that does entail reading user input, but not in all cases. I suggested that the language be changed from "reading args" to "providing args" and that how the argument values are determined be explained explicitly. Don't be intimidated by difficulty with English. Using short sentences helps. There's always room for improvement in the doc, especially as concerns its accessibility by people whose mother tongue is not English. ^ permalink raw reply [flat|nested] 11+ messages in thread
