Amiga 500/1000/2000 version MEANSI.EXE MSDOS ANSI graphics version MEDG10.EXE Data General 10 PC version MEIBM.EXE IBM-PC CGA/MONO/EGA version METIPC.EXE TI Professional version MEZ309.EXE Zenith 100 PC series version MicroSPELL 1.0 is also available. 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 sometime in 1989. 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. 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, and AMIGA 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 licences 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: USmail: Daniel Lawrence 617 New York St Lafayette, IN 47901 ARPA: nwd@j.cc.purdue.edu FIDO: The Programmer's Room 201/10 (317) 742-5533 Voice: (317) 742-5153 evenings and weekends IMPORTANT NOTE ============== On the Atari ST, be sure that MicroEMACS is installed as a GEM application from the GEM desktop. If this is not done, MicroEMACS will grow confused about the state of the mouse, and ring the bell alot to alert the user to the problem. (Mouse handling on the Atari is both complex and tripled layered....). New Features since version 3.9 ============================== *** Multiple Marks now supported The commands set-mark (M-<space>) and exchange-point-and-mark (^X^X) both now accept a numeric argument from 0 to 9 allowing up to 10 marks to be set in a buffer. All region commands still work with mark 0 but the other marks can be used to make navigating around a complex buffer simpler. Also the goto-mark (M-^G) command allows you to go to one of these marks. *** More function key support Under UNIX BSD4.3, V7 SUN, XENIX and some other V5 systems MicroEMACS can now use the TERMCAP entry of the current terminal and decode it's function keys. Also all function key bindings have been renamed to make them machine independant. The CMDFIX program/source distributed along with MicroEMACS will allow you to automaticaly translate old command files to the new bindings. *** Crypt algorithm much better Yes, we found a really bad problem in the security of the encryption algorithm. This has been fixed. Set the environment variable $oldcrypt to TRUE to read in your old encrypted file, and set it to FALSE to write it out again with the new algorithm. *** End-of-word Bending to popular demand, I added an end-of-word command which advances to the end of the current word rather than the beginning of the next word (as with next-word). *** Command line switch to initialize variables The -i switch on the command line allows you to give environment variables a value on the way into EMACS. For example: emacs -i$sres VGA <file> edits <file> in VGA mode on a properly equipped IBM-PC. *** New Hooks added $writehook to execute macroes when writing files. added $exbhook to execute macro when exiting an old buffer. added $bufhook to execute macro when entering a new buffer. *** Trim whitespace function The &trim function strips the trailing whitespace off of a user expression. *** Changed trim/entab/detab commands Now trim-line(^X^T), entab-line(^X^E), and detab-line(^X^D) work on the current region if they have no arguments. These commands are now also called trim-region, entab-region and detab-region. The old names will hang about for a version, then disappear. *** Foreign language text constants MicroEMACS may now be compiled with its internal messages in ENGLISH, GERMAN, DUTCH, PIGLATIN, SPANISH, and FRENCH. The $language variable contains the name of the language of the current version. All command names are still in english to allow macros to be used between versions. Notice that the standard startup files and command files have not been translated, thus the function key window is in english. Only the text messages generated by EMACS itself are translated. *** Upper/Lower case mapping Users can now arbitrarily reset the upper/lower case mapping tables using the &slow and &supper functions. For example: &slow "e" "E" causes a lower case "e" to translate to an "E" when upper cased. This is fairly useful in various foreign languages with unusual and magical casing rules. *** MicroSoft mouse support The MicroSOFT and compatible mice are now supported on the IBM-PC. Mousing commands have changed considerably and are consistent across all supported environments. See the reference manual's new chapter on mousing. *** New user input function >c allows a macro to get an EMACS command key sequence from the user. the resulting string is suitable for binding commands. *** Tab variables $softtab can be used to cause EMACS to use spaces to tab to multiples of $softtab using spaces. If this is zero, EMACS will use hard tabs. $hardtab specifies how many columns between hard tabs. The default value is 8, but may be changed by the user. *** New "safe" file saving Now MicroEMACS write all its output files to a temporary file, then deletes the original, then renames the temp file as the original. This makes system crashes a lot easier to live with. (This behavior can be toggles with the $ssave variable). Notice that $ssave turned on under UNIX will cause your file privledges to be reset to your current umask. *** Horizontal window scrolling Now, by default, when you go beyond the 80th column of the screen, the entire current window scrolls to the left. This makes editing wide tables much more pleasant. $hscroll toggles between this and the old (single line scroll) behavior. $fcol sets what text column is in the first column of the screen. $hjump determines how many characters the screen scrolls right or left. *** More Debugging features The ^XG (display) command prompts the user for a variable name and displays its value (as opposed to execute-command write-message $var). The describe-variables command lists all the current environmental and user variables and their contents in a buffer. *** Named macroes are now bindable The macro-to-key (^X^K) command allows you to bind a keystroke to a named function. Very usefull, this lifts the limit of 40 macroes tied to keys. The older "execute-macro-n" functions will dissapear some day, so please move to this! The describe-bindings function now will list the defined macroes after the built-in functions along with their bindings. *** Hidden modelines??? If you are writing an emacs macro you can hide the emacs modelines by setting $modeflag to FALSE. *** Smooth scrolling If you are of the school that prefers the screen to ride up a line at a time instead of by half windows (I am not BTW), set $sscroll to TRUE. *** Recall last printed statement The last text printed by emacs on the command line can be recalled by querying $lastmesg. Look near the end of the new emacs.rc file to see how this works. *** VGA support IBM's VGA display adapter in 50 line mode is now supported. *** Optimizations! Some internal optimizations have cause a speed increase of apx 30% to the speed of macro execution under all environments. Calling a different level of I/O functions has speed up disk I/O by apx 30% on the IBM-PC and under UNIX. *** CMODE improved CMODE now trims trailing whitespace when the enter key is used, and copies its indentation from the last non-blank line. Blank lines in the middle of a function will no longer cause emacs to forget its indentation level. *** Query-replace bug fixed A rather long standing bug which caused emacs to lock up when aborting a query-replace with the '.' character has been eliminated. *** New Search Algorithm A new search algorithm, written by Geoff Gibbs, implementing the Boyer/Moore search algorithm has speed up all non-MAGIC searches by over 30 TIMES! *** Partial Mouse support added The Atari 512/1040ST, the DEC VAX system under VMS, the IBM-PC with a Microsoft compatible mouse, and the Commodore AMIGA now support mouse usage. Text can be cut and pasted from one buffer to another. Window sizes can be adjusted easily. Mouse support for other operating systems will be forthcoming. New environment variables added for mice include: $xpos Cursor column of last mouse button click $ypos Cursor row of last mouse button click *** Microsoft C Fixes Various fixes have made MicroEMACS compile well under Microsoft C version 5.0 *** New computers supported The WICAT computer is now supported under the MSC operating system. Also the Data General mainframe computers are supported. *** New Compilers supported Mark Williams C on MSDOS is supported. Datalight C under MSDOS is now fully supported as well. *** Rewritten fill-paragraph Fill-paragraph has been rewritten. It is now generally four times faster, and its speed is now related to the size of the paragraph, rather then the square of the size of the largest line, as previously. *** -e switch changed The -e "EDIT" command line switch has been changed to -c "changeable" to allow the -e to be used to automatically execute error.cmd from the command line. This is very useful from Mark Williams C for error parsing. *** New mechanism for hooks Hooks are ways of attaching macroes to MicroEMACS as it is doing specific actions. In the past these were bound to illegal keystrokes. This mechanism is now that there is an environment variable for each of these "hooks" that contains the name of a macro to execute at hook time. These must be one of the built in functions (including execute-macro-<n>) for now. Hooks include: $readhook executes immediately before reading a file, after it's buffer has been created. $wraphook executes when it is time to do a word wrap. This is set to wrap-word by default. $cmdhook executed immediately before MicroEMACS waits for a command from the user. *** select-buffer upgraded A numeric argument to select-buffer causes the target buffer to become "invisible"... ie not listed in the buffer list. Also, when typing in a buffer name interactivly, the space bar will attempt to complete the name from the available buffer list. *** Prefix keys upgraded. More than one key can now be bound to meta-prefix and ctrlx-prefix. Also the terminating character for search and replace strings defaults to the last thing bound to the meta-prefix, and can be reset by setting the $sterm variable. *** Completion routines rewritten Command names, buffer names and file names under some operating systems now share a common completion routines. Typing in a portion of a name and hitting the space bar, meta key or tab key will cause MicroEMACS to attempt to complete the name for you. *** AMIGA INTUITION support The mouse, window resizing and close gadgets are no properly supported on the Commodore Amiga. THINGS TO COME: =============== For the next version, I will be concentrating on: (No promises on the time, I will be concentrating on some other programs for a while) 1) Macintosh support 2) Adding a compiler to the execution language 3) Support for a speaking EMACS to allow sightless people to edit text (AMIGA first)
