MG 1b README March 15, 1987
MicroGnuEmacs (mg) is a Public Domain EMACS style editor. It is
"broadly" compatible with GNU Emacs, the latest creation of Richard M.
Stallman, Chief GNUisance and inventor of Emacs. GNU Emacs (and other
portions of GNU as they are released) are essentially free, (there are
handling charges for obtaining it) and so is MicroGnuEmacs. You may
never have to learn another editor. (But probably will, at least long
enough to port MicroGnuEmacs...)
MicroGnuEmacs is not associated with the GNU project, and does not
have the copyright restrictions present in GNU Emacs. (However, a few
of the system dependent modules do have copyright notices, specificly
the VMS termcap routines and the amiga specific routines. Look at the
source code for exact copyright restrictions.) The MicroGnuEmacs
authors individually may or may not agree with the opinions expressed
by Richard Stallman and the GNU project.
This program is intended to be a small, fast, and portable editor for
people who can't run real Emacs thing for one reason or another. It
is compatible with GNU because there shouldn't be any reason to learn
more than one Emacs flavor. We have excised most MicroEMACS features
that were incompatible with the big brother, and added missing
features that seemed essential.
There are at least two other major versions of MicroEMACS in
circulation. One comes from Daniel Lawrence, (based on an old version
from Dave Conroy) and is available from mod.sources. It uses a 3.x
version numbering scheme, and the latest I know about is 3.8b. It has
some features not found in MicroGnuEmacs, missing others, is bigger,
and is incompatible with GNU Emacs. It might be a better choice for
you if you *must* have something not present here and can't run GNU.
Another variety uses a different numbering scheme, and is up to v30.
This also comes from mod.sources, and is the latest version from the
original MicroEMACS author Dave Conroy. MicroGnuEmacs is derived from
this version, and we hope to replace it.
Code will move fairly easily between MicroGnuEmacs and v30
derivatives. It will not move easily to the 3.x strain because of
diverging ideas about how things should work internally. Command
functions and keymapping, for instance, are completely different
between the two flavors.
This is the second distribution release of MicroGnuEmacs. (It went
through four beta releases to iron out the changes made by the various
autors.) Beyond the work of Dave Conroy, author of the original
public domain v30, the current version contains the work of:
mwm@ucbopal.berkeley.edu Mike Meyer
mic@ngp.utexas.edu Mic Kaczmarczik
blarson@usc-eclb.arpa Bob Larson
People who have worked on previos versions of MicroGnuEmacs:
rtech!daveb@sun.com Dave Brower
These systems are known to work in the current version:
4.2 & 4.3 BSD Unix, Sun 3.2
OS9/68k
VMS
Amiga
System V
Eunice
Primos
Cpm/68k
Atari ST
As far as MG is concerned, Ultrix-32 is equivalent to BSD unix.
It should support MSDOS, PCDOS, and the Rainbow if you swipe the sys
and tty files from the v30 distribution and modify them as specified
in the file systty.mods. It obviously hasn't been tested.
How to Make a MicroGnuEmacs
---------------------------
On UNIX at least, it's easy. (Note that even on these systems you may
want to change a compile time option.) If you have BSD UNIX, do:
ln sys/bsd/Makefile .
make
For System V, do:
ln sys/sysv/Makefile .
make
There are several other directories under sys: osk, vms, eunice,
amiga, atari, prime and cpm68k. You should follow the directions
contained therein to make one of those versions.
For most systems (everyting except the amiga, atari, and cpm68k
currently), the termcap terminal definition is used. There is a
readme file in the termcap subdirectory of the tty directory
explaining what entries are used and how. (Termcap is a way to do
display manipulation in a terminal independent manner.)
----------------------------------------------------------------------
Known limitaions and minor bugs descovered immeditatly before release:
A newline will be appended to the last line of a file if it does
not have one.
There is a fixed maximum line length on files read. (Defaults
to 256, but this may be changed at compile time.)
See functions for function by function differences from real
GNU Emacs.
DPROMPT code has not been added to ttyio.c for all systems
where it could be supported.
The Amiga code has not been extensivly tested with all options
on all compilers. A problem have been discovered but not
duplicated, possibly a compiler problem.
The System V support is actually UNICOS (yes, MicroGnuEmacs
runs on a Cray). How well it works, if at all, on SysVr? is
unknown.
------------------------------------------------------------------------
If you have a change to make that you think should be incorporated
into the next version of MicroGnuEmacs, send it the mg-support mail
list. Addresses are:
mg-support@berkeley.edu
ucbvax!mg-support
Support for additional systems and terminals should include being
available for beta testing as other changes are made. (Send a short
note to mg-support.) If you can't reach one of us via a computer
network, I suppose you could send a change to my snail mail address
below on 5" os9 format disks or 9 track tape (ANSI variable label or
Prime magsav format), but this efectivly rules you out as a potential
beta tester. (Don't expect the disk or tape back unless you inculude
a SASE with sufficent postage.) I will not be sending out copies on
magnetic media, so please don't ask. If you somehow got an incomplete
or non-standard copy, (i.e. missing one of the sys directories
mentioned here as working) complain to who you got it from not to me.

Alternatively, and under the same conditions, you can send either a 3"
AmigaDOS format disk or a 9 track tape (Unix tar format) to:
