MicroEMACS 3.9 Release Notes July 22, 1987 ********************************************************************** (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..... The Programmer's Room FIDO 201/2 (317) 742-5533 24 hours 300/1200 baud Also it should be online on the following BBS's: The Starship Trooper Fido 201/1 (317) 423-2281 2400 [These following two are open from 10pm till 5pm and only while Purdue is in session] The NightStaff Fido 201/4 (317) 495-4270 1200 The Access Violation Fido 201/5 (317) 495-4270 9600 There it is arranged as three MSDOS .ARC files, EMACSDOC.ARC which contains the documentation and command files, EMACSSRC.ARC which contains the sources and the UNIX Makefile, and EMACSEXE.EXE which contains the MSDOS executables. Also all the various executables are available individually. EMACSDOC.ARC includes the files: README This file (These four files should be in your path for the standard setup) EMACS.RC Standard startup file NEWPAGE.CMD Shifted Function key Pager PPAGE.CMD Programming page WPAGE.CMD Word processing page BPAGE.CMD Block and box manipulation page ME110.RC HP110 startup file ME150.RC HP150 startup file AMIGA.RC AMIGA ".emacsrc" startup file ST520.RC ATARI ST startup file EMACS.HLP Online help file EMACS.MSS MicroSCRIBE format of EMACS.TXT EMACS.TXT EMACS BEGINNER'S/REFERENCE MANUAL AZMAP.CMD Translate AZTEC .SYM files to .MAP BDATA.CMD BASIC Data statement builder FINDCOM.CMD Find mismatched C comments FUNC.CMD Allow function keys on systems with non (like UNIX) MENU.CMD Sample Menu system MENU1 datafile for menu system SHELL.CMD Sample interactive MSDOS shell TRAND.CMD Generate random numbers and do statistics on them EMACSSRC.ARC includes the files: ALINE.H Atari ST graphic header file ANSI.C ANSI screen driver BASIC.C basic cursor movement BIND.C key binding commands BUFFER.C buffer manipulation commands CRYPT.C encryption functions DOLOCK file locking stub routines DG10.C Data General 10 screen driver DISPLAY.C main display driver EBIND.H binding list EDEF.H global variable declarations EFUNC.H function name list EPATH.H default path settings ESTRUCT.H configuration and structure definitions EVAL.C expression evaluator EVAR.H EMACS macro variable declarations EXEC.C macro execution functions FILE.C user file functions FILEIO.C low level file I/O driver HP110.C HP110 screen driver HP150.C HP150(A or C) screen driver IBMPC.C IBM-PC CGA and MONOCHROME driver INPUT.C low level user input driver ISEARCH.C incremental search functions LINE.C text line manipulation functions LOCK.C file locking functions MAIN.C argument parsing and command loop RANDOM.C other random user functions REGION.C region cut & paste functions SEARCH.C search and replace functions SPAWN.C OS interface driver ST520.C ATARI ST1040 screen driver TCAP.C Termcap screen driver TERMIO.C low level I/O driver TIPC.C TI-PC screen driver VMSVT.C VMS screen driver VT52.C VT52 screen driver WINDOW.C window manipulation functions WORD.C word manipulation functions Z309.C Zenith 100 PC series terminal driver EMACSEXE.ARC includes the files: MEIBM.EXE IBM-PC CGA/MONO/EGA version MEANSI.EXE MSDOS ANSI graphics version ME110.EXE HP110 portable version ME150.EXE HP150 version ME309.EXE Zenith 100 PC series version ME520.PRG Atari 520/1040ST version MEAMIGA. Amiga 1000 version 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.

Separate "pages" of shifted function keys are available. Users can write their own "pages". *** New Variables (there are a lot...) $status returns status of last command $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) $disinp sets echoing of characters during input on the command line $wline returns and sets # lines in current window $cwline returns and set current line within window $target returns/sets target for line moves $search returns/sets default search string $replace returns/sets default replace string $match returns last matched string in magic search $cmode returns/sets encoded mode of current buffer $gmode returns/sets encoded global mode (see appendix E 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) $rval child process return value *** 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. *** New functions &and <log> <log> Logical AND &or <log> <log> Logical OR &len <str> returns length of <str> &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.
