A new version of my modifications to GNU Emacs for the Apollo is now available.
This version supports GNU Emacs 18.57, Domain/OS SR10.2 and SR10.3, and the
latest release of the Domain C Compiler. New features include:
o Network Graphics Terminal Facility
The Network Graphics Terminal Facility allows GNU Emacs to use the Apollo
GPR support on one node's display while the Emacs editor itself runs on
another machine, which need not even be an Apollo. Communication between
the NGT (Network Graphics Terminal) process and GNU Emacs is performed via
a TCP/IP connection. This facility is particularly useful when two Apollo
nodes are able to communicate via TCP/IP but not via DDS (Domain
Distributed Services) directly, or when you are sitting in front of an
Apollo display but must run an Emacs on a non-Apollo machine.
The NGT protocol is optimized for supporting GNU Emacs redisplay and is
more efficient than the X11 protocols. In addition, text strings displayed
via the NGT protocol are fed through a text compressor to minimize the use
of communication bandwidth; thus NGT will perform much better than X11 when
the TCP/IP connection is made over a slow link, such as 9.6kb/s or 56kb/s
leased lines. Even cut/paste commands are supported with NGT.
o Building an NFS shared Emacs on non-Apollo Machines
Even though non-Apollo machines do not support a compound executable format
that can be executed on multiple machine types, it is possible to invoke
Emacs from many machine types from a single NFS source area. This
distribution includes configuration files for the following machines in
addition to the Apollo: HP300, HP800, IBM RT, MIPS Ultrix, IBM RISC
System/6000 (RIOS), Sun2, Sun3, Sun386, Sun4, VAX 4.3bsd, and VAX Ultrix.
New features from the last version of my modifications include:
o The keyboard management in this version had been updated to use the GPR
event types GPR_$Coded_Keys, GPR_$Function_Keys, and GPR_$Physical_Keys
which are new in SR10.2 and give GNU Emacs access to all the interesting
key transitions. For example, the REPEAT key can now be defined to be the
Meta Key; REPEAT is much more conveniently located than the RIGHT BOX ARROW
key, and since autorepeat can be enabled for most keys in SR10.2, there is
little need for a repeat key. For compatibility, RIGHT BOX ARROW remains
the default Meta Key. If you want REPEAT as your Meta Key, you need to add
the form (select-apollo-meta-key "RPT") to your ".emacs" and the command
"kbm -R none -A alpha,default" to your ".login" or equivalent.
o Since Domain/OS SR10.2 supports the X11 window system, the GNU Emacs
support for X11 and X menus is enabled as well. When Emacs is invoked from
a pad and GPR is available, it is preferred over X11 unless the "-display"
or "-d" command line argument is specified. When GPR support is being
used, the Emacs variable window-system has the value 'apollo; when X11 is
used, it has the value 'x.
o Domain/OS SR10.1 and Domain/IX SR9.7 are no longer supported.
o "etc/apollo.el" is now loaded before ".emacs", and hence the variables
*apollo-key-bindings-hook* and *preempt-display-manager-bindings* are no
longer available. Any key bindings formerly made by using
*apollo-key-bindings-hook* can now be installed directly; you should call
the function install-apollo-dm-preemptive-key-bindings from your ".emacs" to
install these key bindings if you formerly set
*preempt-display-manager-bindings* to T.
I am distributing this release from labrea.stanford.edu (36.8.0.47). The
following files are available for anonymous ftp from the "pub/gnu" directory:
APOLLO.README README for Apollo GNU Emacs
apollo-emacs.tar.Z Apollo GNU Emacs modifications
As always, to install my Apollo GNU Emacs modifications, uncompress and untar
"apollo-emacs.tar.Z" on top of a unmodified GNU Emacs 18.57 distribution tree,
and consult "APOLLO.README" for building instructions.
Note: There is a bug in SR10.2 tar such that overwritten files are not
necessarily truncated to the proper size. Before you untar the file under
SR10.2, execute the following commands:
rm README etc/APOLLO etc/MACHINES info/dir lisp/cl-indent.el* lisp/info.el*
rm lisp/lisp-mode.el* lisp/paths.el* lisp/rmail.el* lisp/rnews.el*
rm lisp/server.el* lisp/shell.el* lisp/startup.el* src/Makefile src/crt0.c
rm src/dired.c src/dispnew.c src/emacs.c src/fileio.c src/fns.c src/keyboard.c
