From: Keith David Bershatsky <esq <at> lawlist.com> To: 17065 <at> debbugs.gnu.org Subject: bug#17065: 24.3.50; Revise line 5944 of window.el to use `window-width`, instead of `window-total-width`. Date: Fri, 21 Mar 2014 17:32:59 -0800
As to line 5944 of `window.el` -- i.e., `(delta (- new-width (window-total-width window))))` -- the usage of `window-total-width` prevents the user from precisely setting the `window-width` when using *a number* as part of the `alist` -- e.g., `'((window-width . 82))`. This can be demonstrated by the following example: (defun broken-example () (interactive) (window--display-buffer ;; buffer (get-buffer-create "*test*") ;; window (split-window (selected-window) nil 'right) ;; type 'window ;; alist '((window-width . 82)) ;; dedicated t) (message "Window Width: %s" (window-width (get-buffer-window "*test*"))) ) As the Emacs team is well aware, the internal function `window--display-buffer` is used by no less than eleven (11) other functions within the `display-buffer` family of functions. Any of those eleven (11) functions that rely upon `window--display-buffer` for setting the `window-width` with an `alist` in the form of *a number* -- e.g., `'((window-width . 82))` -- will suffer from this problem. My proposed solution would be to replace `window-total-width` with `window-width`. However, I must admit that I do not have sufficient knowledge / expertise to know under what circumstance the `window-total-width` would be used -- I only know that this is what causes the inability to properly set the `window-width` when using many of the `display-buffer` family of functions. Here is a link to the thread that I opened on stackoverflow.com on this same issue: http://stackoverflow.com/questions/22565759/window-display-buffer-how-to-precisely-set-window-width-at-time-of-creation/22572176#22572176 Thanks, Keith ;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;;; In GNU Emacs 24.3.50.1 (x86_64-apple-darwin10.8.0, NS apple-appkit-1038.36) of 2014-03-19 on MP.local Repository revision: 116808 rgm <at> gnu.org-20140320012152-sdi1j3d5gu6uzm81 Windowing system distributor `Apple', version 10.3.1038 Configured using: `configure --with-ns' Important settings: locale-coding-system: utf-8-unix Major mode: Text Minor modes in effect: whitespace-mode: t linum-mode: t hl-line-mode: t lawlist-delete-selection-mode: t global-lawlist-scroll-bar-mode: t lawlist-scroll-bar-mode: t flyspell-mode: t shell-dirtrack-mode: t desktop-save-mode: t tabbar-mode: t highlight-parentheses-mode: t font-lock-mode: t blink-cursor-mode: t visual-line-mode: t transient-mark-mode: t Recent input: <escape> x r e p o r t - e m a c s - b u g <return > Recent messages: Loading /Users/HOME/.0.data/.0.emacs/init.el (source)...
