with the only contents slot. This is possible because each valid window may have either the child window (in vertical or horizontal combination) or buffer to display (for the leaf window). Using that, a lof of operations to traverse and/or change window hierarchies may be simplified. New member horizontal is used to distinguish between horizontal and vertical combinations of internal windows. (WINDOW_LEAF_P, WINDOW_HORIZONTAL_COMBINATION_P) (WINDOW_VERTICAL_COMBINATION_P): New macros. (WINDOW_VALID_P, WINDOW_LIVE_P): Adjust to match struct window changes. * window.c (wset_hchild, wset_vchild): Remove. Adjust all users. Use contents slot, not buffer, where appropriate. (wset_combination): New function. (wset_buffer): Add eassert. (Fframe_first_window): Simplify the loop reaching first window. (Fwindow_buffer): Use WINDOW_LEAF_P. (Fwindow_top_child): Use WINDOW_VERTICAL_COMBINATION_P. (Fwindow_left_child): Use WINDOW_HORIZONTAL_COMBINATION_P. (unshow_buffer): Convert initial debugging check to eassert. (replace_window, recombine_windows, Fdelete_other_windows_internal) (make_parent_window, window_resize_check, window_resize_apply) (resize_frame_windows, Fsplit_window_internal, Fdelete_window_internal) (Fset_window_configuration, delete_all_child_windows, save_window_save): Adjust to match struct window changes. (window_loop): Check for broken markers in CHECK_ALL_WINDOWS. (mark_window_cursors_off, count_windows, get_leaf_windows) (foreach_window_1): Simplify the loop. * alloc.c (mark_object): Do not check for the leaf window because internal windows has no glyph matrices anyway. * dispnew.c (clear_window_matrices, showing_window_margins_p) (allocate_matrices_for_window_redisplay, fake_current_matrices) (allocate_matrices_for_frame_redisplay, free_window_matrices) (build_frame_matrix_from_window_tree, mirror_make_current) (frame_row_to_window, mirror_line_dance, check_window_matrix_pointers) (update_window_tree, set_window_update_flags): Simplify the loop. (sync_window_with_frame_matrix_rows): Enforce live window. Use contents slot, not buffer, where appropriate. * frame.c (set_menu_bar_lines_1): Use WINDOW_VERTICAL_COMBINATION_P and WINDOW_HORIZONTAL_COMBINATION_P. (make_frame_visible_1): Simplify the loop. Use contents slot, not buffer, where appropriate. * xdisp.c (hscroll_window_tree, mark_window_display_accurate) (redisplay_windows, redisplay_mode_lines, update_cursor_in_window_tree) (expose_window_tree): Likewise. Use contents slot, not buffer, where appropriate. * textprop.c (get_char_property_and_overlay): Add CHECK_LIVE_WINDOW to avoid deleted windows. Use contents slot instead of buffer. * buffer.c, dispextern.h, editfns.c, fileio.c, font.c, fringe.c: * indent.c, insdel.c, keyboard.c, keymap.c, minibuf.c, msdos.c: * nsfns.m, nsmenu.m, nsterm.m, print.c, w32fns.c, w32menu.c, xfaces.c: * xfns.c, xmenu.c: Use contents slot, not buffer, where appropriate. |

See the end of the file for license conditions.
This directory tree holds version 24.3.50 of GNU Emacs, the extensible,
customizable, self-documenting real-time display editor.
The file INSTALL in this directory says how to build and install GNU
Emacs on various systems, once you have unpacked or checked out the
entire Emacs file tree.
See the file etc/NEWS for information on new features and other
user-visible changes in recent versions of Emacs.
The file etc/PROBLEMS contains information on many common problems that
occur in building, installing and running Emacs.
You may encounter bugs in this release. If you do, please report
them; your bug reports are valuable contributions to the FSF, since
they allow us to notice and fix problems on machines we don't have, or
in code we don't use often. Please send bug reports to the mailing
list bug-gnu-emacs@gnu.org. If possible, use M-x report-emacs-bug.
See the "Bugs" section of the Emacs manual for more information on how
to report bugs. (The file `BUGS' in this directory explains how you
can find and read that section using the Info files that come with
Emacs.) See `etc/MAILINGLISTS' for more information on mailing lists
relating to GNU packages.
The `etc' subdirectory contains several other files, named in capital
letters, which you might consider looking at when installing GNU
Emacs.
The file `configure' is a shell script to acclimate Emacs to the
oddities of your processor and operating system. It creates the file
`Makefile' (a script for the `make' program), which automates the
process of building and installing Emacs. See INSTALL for more
detailed information.
The file `configure.ac' is the input used by the autoconf program to
construct the `configure' script. Since Emacs has some configuration
requirements that autoconf can't meet directly, and for historical
reasons, `configure.ac' uses an unholy marriage of custom-baked
configuration code and autoconf macros.
The shell script `autogen.sh' generates 'configure' and other files by
running the GNU build tools autoconf and automake, which in turn use
GNU m4 and Perl. If you want to use it, you will need to install
recent versions of these build tools. This should be needed only if
you edit files like `configure.ac' that specify Emacs's autobuild
procedure.
The file `Makefile.in' is a template used by `configure' to create
`Makefile'.
The file `make-dist' is a shell script to build a distribution tar
file from the current Emacs tree, containing only those files
appropriate for distribution. If you make extensive changes to Emacs,
this script will help you distribute your version to others.
There are several subdirectories:
`src' holds the C code for Emacs (the Emacs Lisp interpreter and
its primitives, the redisplay code, and some basic editing
functions).
`lisp' holds the Emacs Lisp code for Emacs (most everything else).
`leim' holds the library of Emacs input methods, Lisp code and
auxiliary data files required to type international characters
which can't be directly produced by your keyboard.
`lib' holds source code for libraries used by Emacs and its utilities
`lib-src' holds the source code for some utility programs for use by or
with Emacs, like movemail and etags.
`etc' holds miscellaneous architecture-independent data files Emacs
uses, like the tutorial text and tool bar images.
The contents of the `lisp', `leim', `info', and `doc'
subdirectories are architecture-independent too.
`info' holds the Info documentation tree for Emacs.
`doc/emacs' holds the source code for the Emacs Manual. If you modify the
manual sources, you will need the `makeinfo' program to produce
an updated manual. `makeinfo' is part of the GNU Texinfo
package; you need a suitably recent version of Texinfo.
`doc/lispref' holds the source code for the Emacs Lisp reference manual.
`doc/lispintro' holds the source code for the Introduction to Programming
in Emacs Lisp manual.
`msdos' holds configuration files for compiling Emacs under MSDOG.
`nextstep' holds instructions and some other files for compiling the
Nextstep port of Emacs, for GNUstep and Mac OS X Cocoa.
`nt' holds various command files and documentation files that pertain
to building and running Emacs on Windows 9X/ME/NT/2000/XP.
`test' holds tests for various aspects of Emacs's functionality.
Building Emacs on non-Posix platforms requires tools that aren't part
of the standard distribution of the OS. The platform-specific README
files and installation instructions should list the required tools.
