Fix window geometry 24 years, 2 months

Andy Piper

This patch fixes window geometry to do the right thing (i.e. not include the frame gutters). It means that ispell and friends should now work again. andy 2000-02-25 Andy Piper <andy(a)xemacs.org> * window.c (window_top_frame_gutter_height): new function. (window_top_window_gutter_height): ditto. (window_top_gutter_height): use them. (window_bottom_frame_gutter_height): new function. (window_bottom_window_gutter_height): ditto. (window_bottom_gutter_height): use them. (window_left_window_gutter_width): new function. (window_left_frame_gutter_width): ditto. (window_left_gutter_width): use them. (window_right_window_gutter_width): new function. (window_right_frame_gutter_width): ditto. (window_right_gutter_width): use them. (window_pixel_height): new function. calulate window pixel height with frame gutter involvement. (Fsplit_window): calculate new sizes taking frame gutters into account. (window_char_height_to_pixel_height): don't include frame gutters. (window_char_height): use window_pixel_height. (window_pixheight): rename from window_pixel_height. (change_window_height): use it. (window_pixel_height_to_char_height): don't include frame gutters. (window_char_width_to_pixel_width): ditto. -------------------------------------------------------------- Dr Andy Piper Senior Consultant Architect, BEA Systems Ltd

EGCS and company work, Borland have an offering and Sybase still sell Watcom C and C++, but it has not updated in the last two years AFAIK. Which is a shame, because unlike Kirill, I have seen many problems out of MSVC (inherited, originally, from Zortech), at least in some of the edges of the language.

Re: Use #'(lambda ...) instead of '(lambda ...) 24 years, 2 months

And why is it better. #'(lambda ...) is the reader shorthand for (function (lambda ...)), while '(lambda () is shorthand for (quote (lambda ...)). In interpreted mode, they're equivalent. When compiled, the latter instructs the byte-compiler to compile the lambda form. So (mapcar '(lambda ...) somelist) is slower[1] than (mapcar #'(lambda ...) somelist) To make the story just a bit more spicy, there's also the lambda macro that is a shorthand for (function (lambda ...)). Thus my favorite form of writing the above is: (mapcar (lambda ...) somelist) [1] Actually, that's a lie. In the special case of map* functions, when the byte-compiler finds that the argument is a constant list whose car is the symbol `lambda', it compiles the list. >From bytecomp.el: (defun byte-compile-funarg (form) ;; (mapcar '(lambda (x) ..) ..) ==> (mapcar (function (lambda (x) ..)) ..) ;; for cases where it's guaranteed that first arg will be used as a lambda. (byte-compile-normal-call (let ((fn (nth 1 form))) (if (and (eq (car-safe fn) 'quote) (eq (car-safe (nth 1 fn)) 'lambda)) (cons (car form) (cons (cons 'function (cdr fn)) (cdr (cdr form)))) form))))

Crash in latest 21.2 CVS 24 years, 2 months

Vin Shelton

1. I built the latest 21.2 from CVS sources. 2. I fired up XEmacs (not -vanilla and I don't enable gutters.) 3. I brought up the about screen from the Help menu. 4. I brought up the Installation window from the Help menu. 5. I moved the mouse around between the windows and boom!

Yes & no... you can use borland if you want, but it can generally be a bigger pain that it is worth. Supposedly it is better at tracking the C++ standard than most unix compilers and msvc. Don't know how it stacks up against egcs though. -bill p.
