WHAT IS uEmacs/PK?
|
||
|
|
|
||
|
|
uEmacs/PK 4.0 is an enhanced version of MicroEMACS 3.9e. Enhancements
|
||
|
|
have been incorporated by Petri H. Kutvonen, University of Helsinki,
|
||
|
|
Finland <kutvonen@cs.Helsinki.FI>.
|
||
|
|
|
||
|
|
|
||
|
|
WHY IS IT BASED ON AN OLD VERSION OF MicroEMACS?
|
||
|
|
|
||
|
|
In my opinion 3.9e was the best of all MicroEMACSes. Creeping
|
||
|
|
featurism, growing size, and reduced portability made versions 3.10 and
|
||
|
|
3.11 less attractive. MicroEMACS 3.9e was one of the few editors that
|
||
|
|
were truly portable between different flavours of UNIX, PC/MS-DOS, and
|
||
|
|
VAX/VMS. It was pretty robust - although not flawless. uEmacs/PK 4.0
|
||
|
|
includes numerous bug fixes, adds some new functionality and comfort but
|
||
|
|
does not sacrifice the best things (small size and portability).
|
||
|
|
|
||
|
|
|
||
|
|
WHAT IS NEW - COMPARED TO MicroEMACS 3.9e?
|
||
|
|
|
||
|
|
Enhachements:
|
||
|
|
|
||
|
|
o advisory file locking on BSD-derived systems
|
||
|
|
o new screen update algorithm, borrowed largely form "vile" by
|
||
|
|
Paul G. Fox <pgf@cayman.com>, uEmacs can now be used on slow (1200 bps)
|
||
|
|
connections because it uses terminal scrolling capabilities
|
||
|
|
o new variables $scroll, $jump, and $overlap to control scrolling
|
||
|
|
o uEmacs reacts to windows size change signals (UNIX), also from "vile"
|
||
|
|
o automatic file name completion, works under UNIX and PC/MS-DOS
|
||
|
|
o functions keys on VT200 style keyboards can be used
|
||
|
|
o new command: justify-paragraph (Meta J)
|
||
|
|
o something important for us Europeans: allow the use of 8 bit ISO Latin 1
|
||
|
|
alphabet (UNIX and VMS), on an IBM-PC the accented characters are
|
||
|
|
interpreted as letters too
|
||
|
|
o the characters {|}[\] can be interpreted as letters, these are
|
||
|
|
frequently used as "national replacement characters" especially in
|
||
|
|
the Nordic countries
|
||
|
|
o allow use of XON/XOFF flow control: alternative key sequences for
|
||
|
|
^S and ^Q, don't disable flow control
|
||
|
|
o speed up reading of files (under VMS especially)
|
||
|
|
o new variable $tab, hardware tab stop (4 or 8)
|
||
|
|
o automatic configuration on some common systems
|
||
|
|
o new style mode line, includes percentage indicator
|
||
|
|
o new help file
|
||
|
|
|
||
|
|
Bug fixes - not very interesting:
|
||
|
|
|
||
|
|
o use TI and TE termcap strings, uEmacs works now correctly under
|
||
|
|
Sunview and OpenWindows
|
||
|
|
o use old protection mask on existing files (VMS)
|
||
|
|
o catch data overrun errors (VMS)
|
||
|
|
o allow VMS file names with characters < and >, replacements for [ and ]
|
||
|
|
o allow ANSI screens larger than 24 lines
|
||
|
|
o fix add/delete(-global)-mode
|
||
|
|
o display EOF as char = 0x0, not as garbage
|
||
|
|
o allow upper case letters in answers
|
||
|
|
o fix command interpreter spawning
|
||
|
|
o don't use reverse video on some (TVI925 style) terminals
|
||
|
|
o fix message line writing
|
||
|
|
o fix replace/undo
|
||
|
|
o fix &left and &mid functions
|
||
|
|
o fix documentation
|
||
|
|
o smaller bug fixes are too numerous to mention
|
||
|
|
|
||
|
|
Something is gone:
|
||
|
|
|
||
|
|
o removed (obsolete and untested) support for Amiga, Atari, and Mac
|
||
|
|
|
||
|
|
|
||
|
|
WHERE HAS IT BEEN TESTED?
|
||
|
|
|
||
|
|
uEmacs/PK 4.0 has been tested by myself on the following platforms:
|
||
|
|
|
||
|
|
IBM PC and compatibles, PC/MS-DOS 3.2 and up
|
||
|
|
Sun 3, SunOS 4.1.1
|
||
|
|
SPARC, SunOS 4.1.X and 5.{2|3|4|5} (Solaris 2)
|
||
|
|
VAX 8800 and 6000-420, VMS 5.4
|
||
|
|
DECstation 3100, Ultrix V4.1
|
||
|
|
IBM RS/6000, AIX 3.1.5
|
||
|
|
IBM PS/2, UNIX System V/386 Release 3.2
|
||
|
|
uVAX II, Ultrix V2.0
|
||
|
|
AT&T 3B2/400, UNIX System V Release 2.0
|
||
|
|
Various Toshiba i486 laptops, Linux 0.99pl13 thru 2.0.21
|
||
|
|
|
||
|
|
I have no reason to believe that there would be any problems to port
|
||
|
|
uEmacs/PK 4.0 to any reasonable BSD-, OSF/1-, or SVR4-based UNIX system.
|
||
|
|
|
||
|
|
|
||
|
|
HOW CAN I GET IT?
|
||
|
|
|
||
|
|
uEmacs/PK is available by anonymous FTP from ftp.cs.Helsinki.FI (IP
|
||
|
|
address can change) in the directory pub/Software/Local/uEmacs-PK. You
|
||
|
|
cannot get it by email of uucp. Hopefully it will bee soon available
|
||
|
|
from other file servers too.
|
||
|
|
|
||
|
|
|
||
|
|
WHAT IS IN THE PACKAGE
|
||
|
|
|
||
|
|
o em-4.0.<x>.tar.gz: full source, make and command files to build the
|
||
|
|
editor, reference manual as a MS-Write document,
|
||
|
|
tarred and gzipped, for patchlevel <x>
|
||
|
|
|
||
|
|
o there used to be a packages with binaries for PC/MS-DOS,
|
||
|
|
SPARC/SunOS4, Sun 3, MIPS/Ultrix, 386/ix, IBM RS/6000, VAX/VMS,
|
||
|
|
if you are really desperate you can try contacting me for an old
|
||
|
|
version of these
|
||
|
|
|
||
|
|
|
||
|
|
HOW TO INSTALL uEmacs/PK?
|
||
|
|
|
||
|
|
o PC/MS-DOS: Compile the package with using Turbo C 2.0 or MSC 6.0.
|
||
|
|
(Pretty obsolete both of these.) There are some support files
|
||
|
|
you might find useful in the full distribution.
|
||
|
|
|
||
|
|
o UNIX: Copy makefile.unx to makefile, edit to taste, look at estruct.h,
|
||
|
|
do a 'make', test the editor, 'make install'.
|
||
|
|
|
||
|
|
o VMS: To compile use '@VMSMAKE', install manually, uEmacs/PK uses a
|
||
|
|
logical name EMACS_DIR to locate its initialization files.

CONTACT INFORMATION
|
||
|
|
|
||
|
|
There will probably not be many new versions of uEmacs/PK, maybe just
|
||
|
|
some bug fixes. I have no intention to develope the code any further.
|
||
|

ACKNOWLEDGEMENTS AND STATUS
|
||
|
|
|
||
|
|
I would like to thank Linus Torvalds and Jyrki Havia for their work on
|
||
|
|
some bugs. uEmacs/PK 4.0.10 included fixes for a number of bugs and it
|
||
|
|
was assumed to be the final release for the UNIX platform. However,
|
||
|
|
there has been a couple of maintenance releases, so the final version is
|
||
|
|
4.0.13. On other platforms there has been no new releases since 4.0.3 in
|
||
|
|
1991.
|
||
|
|
|
||
|
|
April 23, 1995
|
||
|
|
|
||
|
|
And yet another release (thanks Linus)! This is most definitely the
|
||
|
|
really last (not latest) version, 4.0.14. Hmm ... 14 looks nicer than 13.
|
||
|
|
|
||
|
|
May 2, 1996
|
||
|
|
|
||
|
|
Still one more release - or actually a small patch - which closes a
|
||
|
|
potential security hole. Now we are at 4.0.15. This IS the FINAL release!
