[xemacs-hg @ 2003-02-09 09:33:42 by ben] walk-windows, redisplay fixes console-stream.c: Abort when any attempts to output a stream console are made. Should be caught sooner. event-msw.c: Don't redisplay() during sizing when the frame has not yet been initialized completely. event-stream.c, menubar-msw.c, menubar-x.c, menubar.c, menubar.h: Restore in_menu_callback. Bind it in menubar-{msw,x}.c when calling filter functions and the like. Conditionalize on it, not in_modal_loop, when issuing error in `next-event', otherwise we bite the dust immediately -- event-msw.c purposely calls Fnext_event() in a modal loop, and knows what it's doing. redisplay-output.c: Formatting fixes. redisplay.c, window.c, winslots.h: Delete lots of carcasses of attempts to add redisplay support for font-lock -- `pre/post-redisplay-hook', unimplemented junk from FSF (redisplay-end-trigger, `window-scroll-functions', `window-size-change-functions'). If we want to port some redisplay support from FSF, port the `fontified' property. redisplay.c: Put in a check here (as well as redisplay_device()) for a stream frame. We can get here directly through Lisp fun `redisplay-frame'. Abort if frame not initialized. redisplay.c: Check for stream frames/devices. window.el: walk-windows was broken when a frame was given to WHICH-FRAMES. it would loop forever. The FSF version fixes this but i didn't sync to them because (a) it conses (bad for lazy-lock), (b) it calls select-window.

@quotation
  Most of the XEmacs text editor is written in the programming
language called XEmacs Lisp.  You can write new code in XEmacs Lisp and
install it as an extension to the editor.  However, XEmacs Lisp is more
than a mere ``extension language''; it is a full computer programming
language in its own right.  You can use it as you would any other
programming language.

  Because XEmacs Lisp is designed for use in an editor, it has special
features for scanning and parsing text as well as features for handling
files, buffers, displays, subprocesses, and so on.  XEmacs Lisp is
closely integrated with the editing facilities; thus, editing commands
are functions that can also conveniently be called from Lisp programs,
and parameters for customization are ordinary Lisp variables.

  This manual describes XEmacs Lisp.  Generally speaking, the earlier
chapters describe features of XEmacs Lisp that have counterparts in
many programming languages, and later chapters describe features that
are peculiar to XEmacs Lisp or relate specifically to editing.
