new macros in dispextern.h, frame.h and window.h. (make_window): Initialize new members left_margin_cols, right_margin_cols, left_fringe_width, right_fringe_width, fringes_outside_margins, scroll_bar_width, and vertical_scroll_bar_type. (coordinates_in_window): Adapted to new fringe/margin positions and per-window fringes and scroll-bars. Fix bug related to incorrectly adjusting coordinates by frame's internal_border_width (the effect normally negible since the internal_border_width is typically 0 or 1 pixel, but very noticeable for an internal_border_width of e.g. 25 pixels). Upon successful return (other than ON_NOTHING), the coordinates are now always properly converted to window relative for the given display element. (window_from_coordinates): Add new parameters wx and wy to return the window relative x and y position in the returned window and part. A null arg means, don't return the position. All callers changed. (adjust_window_margins): New function which may reduce the width of the display margins if a window's text area is too small after resizing or splitting windows. (size_window): Fix bug that did not account for display margin widths when checking the minimum width of a window; use adjust_window_margins. (set_window_buffer): Call Fset_window_fringes and Fset_window_scroll_bars to setup per-window elements. Add new arg KEEP_MARGINS_P. Non-nil means to keep window's existing display margin, fringe widths, and scroll bar settings (e.g. after splitting a window or resizing the frame). All callers changed. (Fset_window_buffer): New arg KEEP_MARGINS. All callers changed. (Fsplit_window): Duplicate original window's display margin, fringe, and scroll-bar settings; then call Fset_window_buffer with KEEP_MARGINS non-nil. This fixes a bug which caused a split window to only preserve the display margins in one of the windows. When splitting horisontally, call adjust_window_margins on both windows to ensure that the text area of the new windows is non too narrow. This fixes a bug which could cause emacs to trap if the width of the split window was less than the width of the display margins. (window_box_text_cols): Renamed from window_internal_width. All uses changed. Adapt to per-window fringes and scroll bars. Fix bug that caused vertical separator to be subtracted also on window frames. Fix another bug that did not reduce the returned value by the columns used for display margins. (window_scroll_line_based): Fix bug related to scrolling too much when display margins are present (implicitly fixed by the fix to window_box_text_cols). (scroll_left, scroll_right): Fix bug related to scrolling too far by default when display margins are present (implicitly fixed by the fix to window_box_text_cols). (struct saved_window): Rename members left to left_col, top to top_line, width to total_cols, height to total_lines, orig_top to orig_top_line, orig_height to orig_total_lines. All uses changed. New members left_margin_cols, right_margin_cols, left_fringe_width, right_fringe_width, fringes_outside_margins, scroll_bar_width, and vertical_scroll_bar_type for saving per-window display elements. (Fset_window_configuration): Restore display margins, fringes, and scroll bar settings. This fixes a bug which caused display margins to be discarded when saving and restoring a window configuration. (save_window_save): Save display margins, fringes, and scroll bar settings. This fixes a bug which caused display margins to be discarded when saving and restoring a window configuration. (Fset_window_margins): Do nothing if display margins are not really changed. Otherwise, call adjust_window_margins to ensure the text area doesn't get too narrow. This fixes a bug which could cause emacs to trap if setting display margins wider than the width of the window. (Fset_window_fringes): New defun to allow user to specifically set this window's fringe widths and position vs. display margins. (Fwindow_fringes): New defun to return window's actual fringe settings. (Fset_window_scroll_bars): New defun to allow user to specifically set this window's scroll bar width and position. (Fwindow_scroll_bars): New defun to return window's actual scroll bar settings. (compare_window_configurations): Also compare display margins, fringes, and scroll bar settings. (syms_of_window): Defsubr new defuns for fringe and scroll bars. |

This directory tree holds version 21.3.50 of GNU Emacs, the extensible,
customizable, self-documenting real-time display editor.
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. See the file BUGS for more information on
how to report bugs.
See the file etc/NEWS for information on new features and other
user-visible changes in recent versions of Emacs.
The file INSTALL in this directory says how to bring up GNU Emacs on
various systems, once you have loaded the entire subtree of this
directory.
The file etc/PROBLEMS contains information on many common problems that
occur in building, installing and running Emacs.
Reports of bugs in Emacs should be sent to the mailing list
bug-gnu-emacs@gnu.org. 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.in' 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.in' uses an unholy marriage of custom-baked
configuration code and autoconf macros. If you want to rebuild
`configure' from `configure.in', you will need to install a recent
version of autoconf and GNU m4.
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-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 the Zippy the Pinhead
quote database. The contents of the `lisp', `leim', `info',
`man', `lispref', and `lispintro' subdirectories are
architecture-independent too.
`info' holds the Info documentation tree for Emacs.
`man' 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 version 4.2 or later of Texinfo.
`lispref' holds the source code for the Emacs Lisp reference manual.
`lispintro' holds the source code for the Introduction to Programming
in Emacs Lisp manual.
`msdos' holds configuration files for compiling Emacs under MSDOG.
`vms' holds instructions and useful files for running Emacs under VMS.
`nt' holds various command files and documentation files that pertain
to building and running Emacs on Windows 9X/ME/NT/2000/XP.
`mac' holds instructions, sources, and other useful files for building
and running Emacs on the Mac.
Building Emacs on non-Posix platforms requires to install 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.
VMS info:
Emacs 19.x and above do not compile out of the box on OpenVMS.
Richard Levitte <levitte@lp.se> is distributing and maintaining a
version of Emacs (currently based on version 19.28, but soon moving to
19.34 and then 20.1) that compiles and works on OpenVMS 5.5 and above
on both VAX and Alpha architectures. For more information see
http://vms.gnu.org/software/released1/emacs.html#get_emacs_1928_kit
There is also some effort going on with Emacs 21. Source code is
available at ftp://ftp.nvg.ntnu.no/pub/vms/emacs/. Look for most
recent stuff with ls -lta.
It is a working "development" version (editing and much more works).
More developers are needed; contact roart@nvg.ntnu.no.
