Subject: v06i079: MicroEmacs, Version 3.7 (uEmacs3.7), Part09/12
Newsgroups: mod.sources
Approved: rs@mirror.UUCP
Submitted by: ihnp4!pur-ee!pur-phy!duncan!lawrence
Mod.sources: Volume 6, Issue 79
Archive-name: uEmacs3.7/Part09
[ This is the latest revision of one of two programs named "MicroEmacs";
when discussing these on the net, or in contacting the authors, make
sure to mention the version number -- in this case 3.7 -- as that is
the easiest way to distinguish between them. Daniel will be posting
uuencoded executables in net.micro.pc and net.micro.amiga; the file
'readme' contains information on how to also get these from him
directly. --r$ ]

X MicroEMACS 3.7 release notes
X
X First off, I would like to thank all the people that send in
Xvarious comments, bug fixes and code segments. I have included as many
Xof these as possible in this current source. All the new features which
Xare larger than a couple of lines are IFDEF'ed by symbols in the
XESTRUCT.H header file. As long as everyone keeps sending these in, I
Xwill keep trying to incorporate them, at least in spirit.
X
X Installation is fairly straight forward. Copy or compile the
Xappropriate version of the editor into EMACS (EMACS.EXE on MS/PC DOS)
Xsomewhere on your executable path. Then copy the emacs.hlp file to one
Xof the directories names in the epath.h file for your system. A startup
Xfile .emacsrc (EMACS.RC on PC/MS DOS) can be placed in the directory
Xpointed to by your HOME environment variable.
X
X[ Note for AMIGA users: Lattice 3.02 was giving me some rather
Xmysterious software task failure errors while compiling some of the
Xmodules. Not having the Amiga long enough to solve this, I upgraded to
XLattice 3.03 and these problems disappeared. If enough people are stuck
Xwith 3.02 and someone comes up with a fix and sends it to me, I will
Xincorporate it into the master sources. Remember to say "stack 16000"
Xbefore compiling the larger files.]
X
X A new reference manual with a listing of all the commands and
Xdescriptions is now included. Commands are listed in logical groups.
XAlso coming in the near future will be a beginner's document to replace
X"emacs.tut".
X
X Also included are two files, "menu.cmd" and "menu1" that make up
Xa simple menu driven interface to MicroEMACS 3.7. For people who prefer
Xmenu driven interfaces, rename "menu.cmd" as "emacs.rc" and place it
Xwhere a startup file would be expected. Also find a place for the text
Xfile "menu1" and change your "emacs.rc" to view-file from that directory
Xfor "menu1".
X
X MicroEMACS 3.7 is distributed on three 5 1/4" diskettes, or as one
X3 1/2" diskette, or as apx. ten shell archives. The shell archives are
Xposted to USENET mod.sources and do not include the executable files.
XThe executable PC and AMIGA versions will also be posted in the relevent
XUSENET groups.

X-------------------------------------------------------------------------------
X MicroEMACS 3.7 - New Features
X
X*** COLOR!!!!
X
X The forground and backgound color of buffers may be set
Xwith the add-mode and add-global-mode commands. Forgound colors
Xare set with capitalized color names, and background colors with
Xlower case color names. Availible colors are the ANSI color set:
X
Xblack, blue, red, green, yellow, cyan, magenta, and white
X
X This feature is only availible on machines that support
Xcolor properly in text mode. (IBM-PC w/color graphics adapter
Xand its clones)
X
X*** Pipe command
X
X The pipe-command (^X-@) command allows you to execute an
Xoperating system command and send the results into a buffer.
XMicroEMACS will make a buffer by the name of "command" for the
Xresults. This is only supported on systems that allow I/O redirection.
X
X*** Filter buffer
X
X The filter-buffer (^X-#) command allows you to send an
Xexisting buffer's contents through a filter which runs under the
Xcurrent operating system. The result replaces the contents of
Xthe current buffer (beware of non-existant filters). Its a good
Xidea to make a backup of the buffer to be filtered.
X
X*** Switchar is fixed
X
X MicroEMACS under PC/MS DOS no longer cares about the
Xsetting of the switchar. It uses the DOS call to look it up and
Xuse it in its fork and system calls.
X
X*** CMODE is configurable
X
X Automatic entering of CMODE for .c and .h extension
Xfiles is now configurable with the ACMODE symbol in estruct.h
X
X*** Query-replace UNDO command
X
X While making a query-replace (M-^R) run, the U key now
Xundoes the last replace.
X
X*** New cursor position report
X
X Re-wrote the buffer-position (^X-=) command to give more
Xusefull information on # lines in file, current line and column,
Xpercentage of text before cursor and the hex value of the
Xcharacter the cursor is on.
X
X*** Word wrapping improved
X
X Words are now only broken at spaces and tabs by the word
Xwrapping algorithm. No more disapearing punctuation delimiters.
X
X*** IBM-PC Color board display driver
X
X A new screen driver for the IBM-PC color board is in the
Xfile IBMPC.C and this vastly improves the paging speed and
Xeliminates the retrace flicker. However, under the color
Xversion, the update while adding text is a little more slugish
Xthan I would hope. We will be working to improve this in the future.
X
X*** Destroying windows!!
X
X A new command, delete-window (^X-0 [zero]) allows you to
Xdelete just the current window from the screen, leaving all the
Xothers intact, (and one of them bigger). This is very convient
Xwhen you have a lot of windows on the screen.
X
X*** Execute Macro commands
X
X Buffers holding commands can now be executed as a "macro". The
Xnames of these buffers is in the form "[Macro nn]" where nn is a number
Xfrom 1 to 20. Each buffer has a corrosponding execute-macro-nn command,
Xthe first ten of which are bound to the shifted function keys on the IBM
Xversions.
X
X*** Macro loading
X
X Macroes can be loaded from a command file (or startup file) with
Xthe use of the store-macro command. For example, to make macro 5 insert
Xa blank line at the begining of the current line, one would put the
Xfollowing in their startup file:
X
X; Open up a line before the current line
X
X5 store-macro
X begining-of-line
X open-line
X[end]
X
X more details on this can be found in the standard startup file
Xand the reference manual.
X
X*** Clear message line
X
X Sometimes when executing macroes you want the last command not
Xto leave a message on the message line at the bottom of the screen. The
Xclear-message-line command does just that.
X
X*** Absolute window resizing
X
X This new command, resize-window (^X-W) allows you to specify the
Xnumber of lines you wish to have in the current window. For example,
XM 12 ^X W forces the current window to a size of 12 lines if possible.
X
X*** Interactive macro arguments
X
X When executing a command line, if any of the arguments begin
Xwith an at sign (@) MicroEMACS will prompt the user for that argument on
Xthe message line, using whatever text follows. A quick macro
Xdemonstating this can be:
X
X; consult file
X2 store-macro
X 2 split-current-window
X previous-window
X view-file "@File to Consult: "
X 8 resize-window
X add-mode "green"
X add-mode "Black"
X next-window
X[end]
X
X*** Buffer Macro arguments
X
X When executing a command line, any arguments begining with a
Xpound sign (#) mean that the argument is to be fetched from the current
Xline of the named buffer. The point in that buffer is then advanced one
Xline if that buffer is not currently being displayed.
X
X*** Split window modified
X
X The split window command normally leaves the cursor in the window
Xwhere the cursor was originaly. Now a numeric argument of one forces the
Xcursor into the upper window, and an argument of 2 forces the cursor
Xinto the lower window.
X
X*** MicroSoft C compiler support
X
X The MicroSoft C compiler (version 3) now can be used
Xsuccessfully to compile MicroEMACS. Use the large data, small program
Xmodel for best results. Thanks to Oliver Sharp for the needed
Xmodifications.
X
X*** VMS terminal support upgraded
X
X VMS now uses the newer terminal modes when executing MicroEMACS.
XAlso some bugs were fixed. Both of these are thanks to Guy Streeter.
X
X*** CMODE enhanced
X
X Lines starting with # as the first non-blank character (ie
Xpre-processer directives) force the # into column one. Also, if
Xmatching open parenthises and braces are being displayed when the
Xclosing one is typed, the cursor will breifly flash to the open and
Xback.
X
X*** Special character quoting
X
X When typing in search/replace strings, ^Q quotes the following
Xcharacter, allowing keys like <ESC> to be searched for.
X
X*** Bindable prefix keys
X
X The META and ^X prefixes may now be bound to other keys. Only
Xone key may be a prefix key at a time, when one of these is rebound, the
Xold key is automatically unbound.
X
X*** New command line options
X
X @<file> Specifies an alternative startup file(s) to
X run instead of emacs.rc or .emacsrc
X
X -g<n> go to line <n> of the first file read in
X
X -s<string> search the first file for <string> and leave
X the cursor there.
X
X*** Wang keyboard support
X
X The Wang-PC keyboard and is function keys are now supported.
X(Define WANG in estruct.h as 1) Thanks to Sid Shapiro for this code.
X
X*** System V support
X
X Unix system V should now compile and execute MicroEMACS
Xproperly. Code for this was submited by Linwood Varney.
X
X*** Unix definitions reorginized
X
X Now only ONE of the unix symbols should be defined when
Xcompiling on unices.
X
X*** Incremental Search added
X
X For those clamering for it.....Isearch commands. This code was
Xsubmited by D. R. Banks and seems to work well. (Later we will merge it
Xwith parts of the normal searching code to conserve space) This is
Xavailible conditionally depending on the ISRCH symbol in estruct.h
X
X*** Insert string command
X
X The insert-string command (unbound) allows you to insert text
Xinto a line from a macro. This can be used to build special help and
Xtext screens.
X
X*** Unmark buffer command
X
X The unmark-command (unbound) allows you to unmark a buffer.
XThis will keep the exit commands from complaining abount unchanged
Xbuffers. This is most usefull when you have built up a text screen from
Xa macro and have no intention of saving it.
X
X*** Special characters
X
X Inside of string argument in macroes, the following special
Xcharacters are active:
X
X ~n newline
X ~t tab
X ~b backspace
X ~f formfeed
X
X*** Fixed large file problems
X
X Several problems caused by keeping character counts in integers
Xhave been fixed by making these counts be longs. Also regions can now
Xbe larger than 65535 chars.
X
X*** Kill buffer re-coded
X
X New kill buffer routines should (and do) work faster. Also an
Xunlimited (except by RAM) amount of text can be killed safely.
X
X*** Word counting
X
X The count-words (M-^C) command counts the number of words,
Xcharacters and lines in the current region. It also gives an average
Xwords/character total.
X
X*** Changed delete-word behavior
X
X Delete-next-word no longer kills the newline as it deletes tha
Xlast word on the line. It does however then delete the newline as it
Xdeletes the first word on the next line.
X
X*** Next/Previous buffer cammands augmented
X
X Both now take a numeric argument to switch to the nth window
Xfrom the top/bottom.
X
X*** Data General Support
X
X MicroEMACS now supprts the Data General System/10 computer under
XMSDOS.
