Add support for child frames on tty The redisplay part is complete. The frame-handling part supports use-cases like Posframe, Corfu, and child frames acting like tooltips. Other use-cases of child frames are not currently supported. In particular, trying to create minibuffer-only child frames on ttys will signal an error. * src/xfaces.c (free_frame_faces): Change formatting slightly. * src/xdisp.c (redisplay_trace, move_tracxe): Print to stderr because stdout screws up terminal display. (init_iterator): Remove a #ifdef HAVE_WINDOW_SYSTEM. (clear_garbaged_frames): Return a bool telling if we cleared matrix. (echo_area_display): Use combine_updates on tty frames. (redisplay_internal): Changes for redisplay of tty child windows. (deep_copy_glyph_row): Take a frame parameter. (display_tty_menu_item): Changes because of function signature changes. * src/w32term.c (w32_read_socket): Don't use FRAME_OBSCRURED_P, which has been removed. * src/w32inevt.c (do_mouse_event): Workaround for mouse events on child frafmes. * src/w32console.c (w32con_write_glyphs, w32con_update_end): Use glyphs' frame for faces. * src/treesit.c (treesit_load_language): Pacify a warning. * src/w32console.c (w32con_clear_end_of_line): Set glyph's frame. * src/terminal.c (cursor_to, raw_cursor_to): Handle case that frame is a child frame. * src/termhooks.h: Declare formerly static functions. * src/term.c (tty_hide_cursor, tty_show_cursor): Make externally visible.

Callers adapted. (Fresume_tty): Act on root frame. (tty_draw_row_with_mouse_face): Handle child frames. (restore_desired_matrix): Make sure glyphs' is live.

(syms_of_term): Defsubr new Lisp functions. * src/minibuf.c (read_minibuf): Use combine_updates for tty frames. * src/frame.h (struct frame): Always define parent_frame. Change 'visible' to be a boolean. Always define 'undecorated' and 'no_accept_focus'. Add 'z_order'. (FRAME_OBSCURED_P): Removed. (FRAME_PARENT_FRAME): Make it a function. (SET_FRAME_VISIBLE): Take a bool parameter, not an int. (FRAME_INTERNAL_BORDER_WIDTH): Don't special-base HAVE_WINDOW_SYSTEM. * src/frame.c (decode_tty_frame): New function. (set_menu_bar_lines): Set menu bar lines and height to 0 for tty child frames. Compute min height differently. (adjust_frame_size): Set FrameCols/Rows only for root tty frames. Mark tty root frame garbaged if child frame is adjusted. Run some code even if not HAVE_WINDOW_SYSTEM. (make_frame): Run some code even if not HAVE_WINDOW_SYSTEM.

See the end of the file for license conditions.
This directory tree holds version 31.0.50 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.
The file CONTRIBUTE contains information on contributing to Emacs as a
developer.
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.) For a list of mailing lists related to Emacs, see
<https://savannah.gnu.org/mail/?group=emacs>. For the complete
list of GNU mailing lists, see <https://lists.gnu.org/>.
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.
The shell script 'autogen.sh' generates 'configure' and other files by
running Autoconf (which in turn uses GNU m4), and configures files in
the .git subdirectory if you are using Git. 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 original source files for the generated files
in lisp/leim. These form the library of Emacs input methods,
required to type international characters that 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.
'lwlib' holds the sources of the Lucid Widget Library used on X.
'oldXMenu' source files from X11R2 XMenu library, used in non-toolkit builds.
'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 MS-DOS.
'nextstep' holds instructions and some other files for compiling the
Nextstep port of Emacs, for GNUstep and macOS Cocoa.
'nt' holds code and documentation for building Emacs on MS-Windows.
'test' holds tests for various aspects of Emacs's functionality.
'modules' holds the modhelp.py helper script.
'admin' holds files used by Emacs developers, and Unicode data files.
'build-aux' holds auxiliary files used during the build.
'm4' holds Autoconf macros used for generating the configure script.
'java' holds the Java code for the Emacs port to Android.
'cross' holds Makefiles and an additional copy of gnulib used to build
Emacs for Android devices.
'exec' holds the source code to several helper executables used to run
user-installed programs on Android.
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.
