|
|
||

|
(C)opyright 1987 by Daniel M. Lawrence
|
||
|
MicroEMACS 3.9 can be copied and distributed freely for any
|
||
|
non-commercial purposes. MicroEMACS 3.9 can only be incorporated
|
||
|
into commercial software with the permission of the current author.
|
||
|
|
||
|
**********************************************************************
|
||
|
|
||
|
MicroEMACS 3.9 is availible in a couple of different ways.
|
||
|
First, it is availible via my bulletin board system.....
|
||
|
|
||
|

|
||
|
FIDO 201/2
|
||
|
(317) 742-5533
|
||
|
24 hours 300/1200 baud
|
||
|
|
||
|
Also it should be online on the following BBS's:
|
||
|
|
||
|

Recently, MicroSPELL 1.0 has been released. This program allows
|
||
|
you to spell check text files and uses MicroEMACS to scan the file,
|
||
|
doing various corrections.
|
||
|
|
||
|
MicroSCRIBE, a fairly SCRIBE compatible text formatter to go
|
||
|
along with these programs will probably be available for beta testing
|
||
|
early spring 1988. This program is turning out to be a lot more complex
|
||
|
than I thought it would be, and is taking more time to get out.
|
||
|
|
||
|
I have in my possesion a port of MicroEMACS 3.8i to the
|
||
|
Macintosh, and I will be incorporating the needed changes for the current
|
||
|
version to support the Macintosh.
|
||
|
|
||
|
As before, I will continue to support these programs, and
|
||
|
encourage everyone to spread them around as much as they can. If you
|
||
|
make what you think are changes that are useful to many, send me the
|
||
|
updates, and as time permits, I will incorporate the ones I understand,
|
||
|
and agree with into the master sources.
|
||
|
|
||
|
MicroEMACS is available on disk directly from my by sending me
|
||
|
$25 per order and a note specifying the disk format and the product that
|
||
|
you need. I can fill orders for IBM-PC high/low density 5 1/4 and 3
|
||
|
1/5, ATARI ST single and double density, AMIGA disks and HP150 disks.
|
||
|
(You do not need to send disks or mailers, I will provide these.) The
|
||
|
distribution set includes on disk all docs, executables and sources.
|
||
|
Also I will register you and you will receive automatic notices of new
|
||
|
versions of all the programs I am releasing.
|
||
|
|
||
|
Commercial lisences to allow MicroEMACS to be incorporated into
|
||
|
other software packages are also available at a reasonable per package
|
||
|
price. Also I am available to do customization of MicroEMACS at an
|
||
|
hourly rate. Send all requests to the address below:

New Features since version 3.8i
|
||
|
===============================
|
||
|
|
||
|
** New standard startup file
|
||
|
|
||
|
The new emacs.rc file is segmented into more parts and loads much
|
||
|
faster than before. Separate "pages" of shifted function keys are
|
||
|
available. Users can write their own "pages".
|
||
|
|
||
|
*** New Variables (there are a lot...)
|
||
|
|
||
|

|
||
|
$palette color palette settings
|
||
|
$lastkey returns last keystroke
|
||
|
$curchar returns and set the ascii number of the
|
||
|
character under the point
|
||
|
$progname always returns "MicroEMACS"
|
||
|
$version always returns the current version ("3.9")
|
||
|
$discmd sets display of messages on the command
|
||
|
line (except via the write-message command)
|
||
|

|
||
|
command line

|
||
|
in emacs.mss to decode this)
|
||
|
$tpause returns/sets the pause for fence matching
|
||
|
(this is in rather arbitrary units which
|
||
|
WILL vary from machine to machine)
|
||
|
$line return/sets the contents of the current line
|
||
|
$gflags global operations flag (see emacs.txt Appendix G)
|
||
|

|
||
|
|
||
|
*** New computers supported
|
||
|
|
||
|
Atari 1040ST all three graphics modes and 50 line mode on a
|
||
|
monochrome monitor. The mouse is bound to the
|
||
|
cursor keys for now.
|
||
|
|
||
|
*** New Compilers supported
|
||
|
|
||
|
Turbo C v1.0 under MSDOS is now a supported compiler.
|
||
|
Mark Williams C on the Atari ST is also supported.
|
||
|
|
||
|
** New directives
|
||
|
|
||
|
!while <condition> loops while <cond> is true
|
||
|
|
||
|
!break breaks out of the innermost !while
|
||
|
|
||
|
!endwhile delimits the end of a !while loop
|
||
|
|
||
|
All !gotos are legal into and out of a !while loop.
|
||
|
|
||
|
*** Autosave mode
|
||
|
|
||
|
This mode saves the file out to disk every time 256 have been
|
||
|
inserted. $asave controls the # of characters between saves, $acount
|
||
|
controls the # of chars to the next save.
|
||
|
|
||
|

|
||
|
&lower <str> lowercase <str>

||
|
&upper <str> uppercase <str>
|
||
|
&rnd <int> generate a random integer between 1 and <int>
|
||
|
&sindex <str1> <str2> search for string 2 within string 1
|
||
|
returning its position, or zero if it fails
|
||
|
&env <str> return value of DOS environment
|
||
|
variable <str>
|
||
|
&bind <str> returns the function name bound to the
|
||
|
key <str>
|
||
|
&exist <str> Does file <str> exist?
|
||
|
&find <str> find file <str> along the PATH
|
||
|
&band <num> <num> bitwise and
|
||
|
&bor <num> <num> bitwise or
|
||
|
&bxor <num> <num> bitwise xor
|
||
|
&bnot <num> bitwise not
|
||
|
&xlate <str1> <str2> <str3>
|
||
|
scan <str1> replacing characters in
|
||
|
<str2> with the coresponding characters
|
||
|
in <str3>
|
||
|
|
||
|
*** Advanced word processing commands
|
||
|
|
||
|
^X^T trim-line trim all trailing whitespace
|
||
|
^X^E entab-line change all multiple char runs to tabs
|
||
|
^X^D detab-line change all tabs to multiple spaces
|
||
|
|
||
|
*** Merged EGA driver
|
||
|
|
||
|
The EGA driver is now part of the IBM-PC driver. This driver now
|
||
|
supports MONO, CGA and EGA cards/modes. (settable by using the $sres
|
||
|
variable)
|
||
|
|
||
|
*** 8 bit characters fully supported
|
||
|
|
||
|
Eight bit characters (including foreign language and line
|
||
|
drawing characters) are now supported on the various micro environments)
|
||
|
|
||
|
*** List Buffers expanded
|
||
|
|
||
|
Given a numeric argument, ^X^B (list-buffers) will now also list
|
||
|
all the hidden internal buffers.
|
||
|
|
||
|
*** -k switch enhanced
|
||
|
|
||
|
If you use the -k (encrypted file) switch on the command line
|
||
|
without a key immediatly following it, it will prompt you for the key to
|
||
|
use to decrypt with.
|
||
|
|
||
|
*** word delete enhanced
|
||
|
|
||
|
with a zero (0) argument, M-D (delete-next-word) deletes the
|
||
|
next word and not any intervening whitespace or special characters.
|
||
|
|
||
|
*** New File read hook
|
||
|
|
||
|
Whenever MicroEMACS reads a file from disk, right before it is
|
||
|
read, whatever function is bound to M-FNR (which is an illegal
|
||
|
keystroke) will execute. By default this would be (nop), but the
|
||
|
standard emacs.rc binds this to a file that examines the file name and
|
||
|
places the buffer int CMODE if the extension ends in a .c or .h. You can
|
||
|
of course redefine this macro to taste.
|
||
|
|
||
|
*** Search Path modified
|
||
|
|
||
|
The order in which emacs looks for all .rc (startup) and
|
||
|
.cmd (command macros) is as follows:
|
||
|
|
||
|
$HOME (the HOME environment variable if it exists)
|
||
|
the current directory
|
||
|
$PATH (executable PATH)
|
||
|
default list contained in epath.h
|
||
|
|
||
|
*** Line length limits removed
|
||
|
|
||
|
Lines of arbitrary length may be read, edited, and written.
|
||
|
|
||
|
*** Out of memory handling improved
|
||
|
|
||
|
EMACS will announce "OUT OF MEMORY" when it runs out of dynamic
|
||
|
memory while reading files or inserting new text. It should then be
|
||
|
safe to save buffers out IF THE CONTENTS OF THE BUFFER ARE COMPLETE at
|
||
|
that time. When a buffer has been truncated while reading, a pound sign
|
||
|
"#" will appear in the first position of the mode line. Also a # will
|
||
|
appear in a buffer listing. If you attempt to save a truncated buffer,
|
||
|
EMACS will ask if you are certain before allowing the truncated file to
|
||
|
be written. As before, still beware of killing blocks of text after you
|
||
|
have run out of memory.
|
||
|
|
||
|
*** DENSE mode on the Atari ST
|
||
|
|
||
|
On an Atari ST monochrome monitor, setting $sres to "DENSE" will
|
||
|
result in a 50 line display.
|
||
|
|
||
|
*** Execute command
|
||
|
|
||
|
Execute-program (^X-$) will execute an external program without
|
||
|
calling up an intervening shell is possible.
|
||
|
|
||
|
*** Better close braces in CMODE
|
||
|
|
||
|
The name says it all, try it.
|
