===            The ME Low End of the Want List             ===
====================================================================

- Multiple key macros, named macros, macros bound to keys
- Recursive editing
- Local syntax tables

====================================================================
===                Enhancement Requests             ===
====================================================================

- Reverse video (I think, at this point in time, my biggest complaint
  with ME2 is lack of support for reverse video, such as highlighting a
  region/rectangle) highlight bar for the current item;
   Jeff Bowyer                         EMail:
   Technical University of Brno        [e-mail]

- Add another option to the case-bag function to reverse case (i.e.
  lower-case letters are converted to upper-case and vice versa),
  similar to Wordstar's Ctrl-OO command.

- I wish compare-marks was more precise:  if mark1 and mark2 are on the
  same line, what is their relation on the line?
    Jeff Bowyer
  You would have to use
    (goto-mark mark1)(x (current-column))
    (goto-mark mark2)(y (current-column))
    and then compare x and y.

- In help.c, function disp_help(), I suggest changing BFNOCARE to
  BFNOCARE | BFINTERACTIVE since it is a user viewable/messable buffer.
  There is a problem with buffer vars no being created there.  Jeff Bowyer

2/94 v3.4        [Released May, 1994]
---- ----
+ New args for (stop-ME-hook):  you can now tell if it was called for
  signals or general shut down. 3/94
+ Made the X11 code work.  1/94
+ Added mouse code (X11 only). 1/94
+ Changed goto-line to current-line.  If no args, returns the current
  line number.  3/94

* Made the Makefiles much nicer, added Borland C Makefiles. 4/94

1/94 v3.3        [Released , 1994]
---- ----

10/93 v3.2        [Released October, 1993]
----- ----
* (file-to-buffer) left the dot at the start of the inserted file.  To
  be consistant with the other insert routines, the dot should be after
  the insert.  Changed insert_file().  OS-filter also changed because it
  uses insert_file().  1/94

7/93 v3.1        [Released August, 1993]
---- ----
* (OS-filter) doesn't work for pipes ("foo | bar").
  Fix: Don't open a stdin unless the caller askes for it.  Could cause
  other problems.  9/93
* Changed (text-color) and (modeline-color) to take a string (instead of
  a number).  (text-color "foreground:background") eg (text-color
  "green:black").  Better for PCs, allows other color systems.  Breaks
  backwards compatibility.  9/93
* Running out of memory is a real pain.  Kevin Jameson
  ([e-mail]) noted that if you run out of memory while
  reading in a file, the file is incomplete.  Writing the file back out
  is a disaster. 10/93
  Fix:  If reading in a file and run out of memory, set the Bad Read
  buffer flag and make the buffer read only.  The write routines won't
  write a buffer with the bad read flag set.
+ Added (cursor-shape).  Cursor shape is a pain on PCs so this allows it
  to be changed.  Mark van der Velden and Bob May finally asked enough
  times for a fix.  9/93

6/93 v3.0        [Released June, 1993]
---- ----
+ Added a read only buffer flag and support.  7/93

* (move-cursor) and (puts) could cause annoying cursor sync problems.
  Fix:  Inform the display code the cursor is out of sync.  7/93

-------------------------
Changes made to ME2 to create ME3:
  - Removed all the front end C code and rewrote it in Mutt.
  - Rewrote lots and lots of code.
  - Added Mutt keywords: forward-char, forward-word, load-code,
    scroll-window, list-keys, stop-ME, stop-ME-hook,
    keystroke-macro, clear-buffer-hook, free-buffer-hook, split-window,
    buffer-to-file, file-to-buffer, version-hook, OS-command, OS-shell,
    prime-ask, read-clock, display-time, idle-hook, create-keymap,
    clear-keymap, install-keymap, bind-key, beep
  - Added more args to: arg-flag, delete-region, update, looking-at,
    free-window, window-ledge, window-length, complete, buffer-name

1/30/93 v2.6        [Released January 30, 1993]
------- ----
* (tab-stops -n) core dumps when (tab).  Han-Wen Nienhuys
  ([e-mail]) 2/93
  Fix:  check tabsize in tab() (random.c).
- Should use the termcap "km" (Meta sets high bit) attribute.  8/92
- Saving undo information can really slow things down when editing at
  the end of buffers with many lines.  Especially noticable on [older]
  PCs.  12/92
  Fixed in ME3
- Undo doesn't work when in overstrike mode.  1/93
- In Mutt Editor 2.5, delete-previous-word stores words in the wrong
  order to the cut-buffer, when using M-C-H more than once.  They are
  appended to the cut buffer, instead of being inserted at the
  beginning.
  From: [e-mail] (Han-Wen Nienhuys)
  Newsgroups: comp.emacs
  Date: 20 Apr 1993 14:56:41 GMT
  Fix:  Not fixed in ME2 but in ME3 Mutt code:  In
  basic.mut:delete-words, prepend region (instead of append) when
  cutting back words.  delete-characters has the same problem, same fix.
  4/93

2/2/92 v2.5        [Released August 30, 1992]
------ ----
+ newline-and-indent doesn't always work right.  The previous lines
    indent was matched, even if the dot was in the whitespace (eg press
    return at the begining of a line and the new line is indented twice
    as much).  Jeff Bowyer
  Fix:  Only match the indent upto the dot.  indent(), random.c  12/92
+ Modified (move-cursor) so it can take text and display it though the
  display code.  Based on suggestion from Jeff Bowyer about popup menus.
  11/92
+ Added clear-buffer-hook and free-buffer-hook.  11/92
+ Renamed buffer-created-hook to create-buffer-hook.  11/92

* window-height and screen-height are inconsistent.  Jeff Bowyer
    ([e-mail]) 10/92
  Fix:  rename window-height to window-length and put a backwards
    compatible window-height in me2.mut.  10/92
* There are lots of places that won't work all that well with 16 bit
    ints - when they overflow or go negative, the results will be
    unpleasent.  I keep hoping I can close my eyes, click my heels
    together three times and they will go away.  dTables are one of the
    biggies (used by bags).
  Fix: John Burnell added some small int checking to the dtable code.
    10/92.  Did more chasing down 2 byte int problems 1/93.
* insert-file doesn't set undo.
  Fixed 10/92.

- Should use the termcap "km" (Meta sets high bit) attribute.  8/92
- Saving undo information can really slow things down when editing at
  the end of buffers with many lines.  Especially noticable on [older]
  PCs.  12/92
  Fixed in ME3
- Undo doesn't work when in overstrike mode.  1/93

2/2/92 v2.4        [Released August 9, 1992]
------ ----
+ Compile me2.mco into ME2 using mco_to_c.  This is way cool because the
    executable can contain as much Mutt code as desired - easy to
    install, less hassles for novices, less questions for me.  Thanks to
    Todd Moody (sjuphil![e-mail]) for the initial idea.  Changed
    main.c a bit to remove loading me2.mco and instead call the internal
    Mutt code.  8/92
  For ME3, I can remove all the system commands and write the entire
    front end in Mutt.  Now that will be totally radaballical.
+ Munged the Makefile(s) to unGNUize them, added comments to try to make
  it easier to compile.  Kevin Knappmiller
  ([e-mail]).  8/92

- insert-file doesn't set undo.

2/2/92 v2.3        [Released May 10, 1992]
------ ----
+ John Burnell added some more support for the IBM PC grey keypad.  5/92

* For SIGWINCH on HP-UX, forgot to reset the signal in the signal
  handler.  6/92
* Nadav Horesh <[e-mail]> found a display problem
  on IBM PCs with super VGA and 132 column mode.  In pcfv.c, getting
  screen info out of the BIOS should have been (unsigned char *)
  ie *((char *)0x0040004AL) should have been *((unsigned char *)0x0040004AL)
  6/92
* Have the regex search routines abort if can't compile the regex.  This
  way, you can see the regex error message.  7/92
* (looking-at '\<') always returns TRUE if dot is on a letter. 4/92
    (looking-at '\>') always returns FALSE. 7/92
  Fix:  Need to pass the RE code the character before the dot (if there
    is one).  7/92

- There are lots of places that won't work all that well with 16 bit
  ints - when they overflow or go negative, the results will be
  unpleasent.  I keep hoping I can close my eyes, click my heels
  together three times and they will go away.  dTables are one of the
  biggies (used by bags).


2/2/92 v2.2        [Released April 12, 1992]
------ ----
+ Atari stuff (from jwahar r.  bammi ([e-mail])) added 5/92.

* Changed ranger2 (help.c) to work around a bug on AIX.  Hope I didn't
  break it.  5/92

- (looking-at '\<') always returns TRUE if dot is on a letter. 4/92
- There are lots of places that won't work all that well with 16 bit
  ints - when they overflow or go negative, the results will be
  unpleasent.  I keep hoping I can close my eyes, click my heels
  together three times and they will go away.  dTables are one of the
  biggies (used by bags).


2/2/92 v2.0        [ME2 beta, released February 28, 1992]
------ ----
* The default load path appended the $HOME directory.  This was a
  problem if you wanted to roll your own (for example) cmode and just
  plug it in (and use the default path).  3/1/92
  Fix:  prepend $HOME.
* Trying to delete a character at the end of a buffer puts a newline in
  the undo buffer.  3/8/92
  Fix:  Do a little better end of buffer checking in bag.c:
  copy_region_to_bag().
* Trying to cut to much with (cut-line) doesn't cut anything.  3/8/92
  Fix:  Don't be so picky in cutbuf.c: cut_line().
* In bind.c, metacmds() called dscrib_bindings() with no args.  John
  Burnell 3/92.  Lint the whole mess to find more little details.

+ John Burnell got the PC and OS/2 versions going.  Added code and pointed
  out boo-boos.  3/92

- There are lots of places that won't work all that well with 16 bit
  ints - when they overflow or go negative, the results will be
  unpleasent.  I keep hoping I can close my eyes, click my heels
  together three times and they will go away.  dTables are one of the
  biggies (used by bags).



====================================================================
====            ME Bug and Change list            ====
====================================================================

9/17/89 (PL2)     [Released February 18, 1990]
-------------
+ Major rewrites of various parts of ME to create ME2.


9/17/89 (PL1)     [Released November 30, 1989]
-------------
- If you are word wrapping and there are more than one white space
    characters that the end of the line, the white space is wrapped, not
    the word.  This is a contrived example because most of the time word
    wrapping happens as you type.
* The default regular expression search pattern can get out of sync with
    the compiled RE.
* MEAT.EXE only:  File name completion would not find files with the
    archive bit reset (ie the file had no attributes bits set).
  Fix:  Check for this case in fxpand().
* (append-to-register) is broken on PCs (or machines with 16 bit ints).
  Fix:  add (int) to RV.val.num in call to reg_append().

9/17/89     [Released October 8, 1989]
-------
* Overstrike mode causes some Mutt programs to misbehave.
  Why:  (tab), (to-col), (newline) and (delete-previous-character) did
    different things in overstrike/insert modes.  Programs that didn't
    reset the mode and used these routines had problems in overstike
    mode.
  Fix:  Make the routines act like they are in insert mode.
* Fast Video PCs only:  If you have several buffers displayed and do a
    "M-X?", the help messages will have bands though them.
  Why:  the clear to end of line routine was using the wrong color
    (sometimes).
  Fix:  Grab the BIOS color.

7/23/89     [Released August 6, 1989]
-------
- MS-DOS only.  If the .mco file and data it allocates is >32k the
    Lattice C library screws up and causes ME to get confused.
  Fix:  When I get a new compiler.

+ Ability to modify mode line - see (modeline-hook) in memutt.doc.
+ Buffer local strings - see (buffer-string) in memutt.doc.
+ Added (bit-and), (bit-or) and (bit-xor).
+ Added (file-exists).
+ Added timeout to (key-waiting).
+ Fixed bug in (next-page) and (previous-page).
+ Added clear-keymap to (bind-to-key) and (bind-local-key).
+ Added (enter-ME-hook) and (leave-ME-hook).

9/5/88 (PL4)    [Released June 27, 1989]
------------
* (complete), (yesno) don't work like (ask).  They won't get arguments
    from the arg list.  This is really a bug in the Mutt Machine.
  Fix:  Messed around with MM internals (mostly stack frames).  One
    result of this is that (ask) and (complete) are a bit different (see
    below).
+ (ask) now takes zero or more args (it use to take one).  So (ask "one"
    2 "three") is now the same as (ask (concat "one" 2 "three")).  No
    Mutt code need be changed because of this but you do need to
    recompile.
+ (complete) - the args were switched.  (complete "prompt" selector) is
    now (complete selector "prompt").  Did this in case someday I want
    to make prompt more than one arg (ala the change to ask).
* Message line stuff: ^M (Enter) and ^J now terminate the interaction.
    ^Q^M or ^QEnter enter ^M and ^Q^J enters ^J.
  Why:  It is nice to be able to get rid of ^Ms (for example in files
    sent to UNIX from MS-DOS) with query-replace and some systems
    convert Enter to ^J which can really screw up message line
    interaction.
+ What strings in ME and MC.
+ Added a magic number to Mutt code to help control versionits.

9/5/88 (PL3)
------------
* The "?" help (the list of matches you get when you hit ?) could be
    better.
  Fix: Added multiple columns and screens.
* Converting filenames to their concanical form is not very robust and
    sometimes screws up processing "." and "..".
  Fix:  Its still not all that robust but works correctly for "." and
    ".." (unless you try to edit a file named "." or "..").
+ Need file name completation.
  Fix:  Wrote and rewrote a whole lotta code.


9/5/88 (PL1)
------------
- Query replace (interactive):  A long arg to "new string" can cause the
    screen to scroll which will cause the cursor to be wierd during the
    replace.
  Fix:
    - add ^L to query replace or query-replace-hook.
    * write query replace in Mutt.
* window-ledge: Can set left edge to a negative value.
  Fix: set ledge to imax(0,value)
* Mark set on line and delete chars to right (on same line) and mark
    reset to dot.
- If a something aborts without calling ctrlg() or (abort), keyboard
    macros not terminated.  I'm not sure this is a problem.


+ Added job control to UNIX versions (ie ability to suspend ME).
+ Handle signals (SIGTERM, SIGHUP) in UNIX.
+ The remembered search and replace patterns are now separate for
  regular and normal searching.  Not convinced this is that great of an
  idea.
+ Renamed RE-string to re-string for consistancy.
