GNU Info (gnus)Extended InteractiveExtended Interactive -------------------- Gnus extends the standard Emacs `interactive' specification slightly to allow easy use of the symbolic prefix (Note: Symbolic Prefixes). Here's an example of how this is used: (defun gnus-summary-increase-score (&optional score symp) (interactive (gnus-interactive "P\ny")) ... ) The best thing to do would have been to implement `gnus-interactive' as a macro which would have returned an `interactive' form, but this isn't possible since Emacs checks whether a function is interactive or not by simply doing an `assq' on the lambda form. So, instead we have `gnus-interactive' function that takes a string and returns values that are usable to `interactive'. This function accepts (almost) all normal `interactive' specs, but adds a few more. `y' The current symbolic prefix--the `gnus-current-prefix-symbol' variable. `Y' A list of the current symbolic prefixes--the `gnus-current-prefix-symbol' variable. `A' The current article number--the `gnus-summary-article-number' function. `H' The current article header--the `gnus-summary-article-header' function. `g' The current group name--the `gnus-group-group-name' function. automatically generated by info2www version 1.2.2.9 |
