Release 0.1.1 of JOE (Joe's Own Editor): Note that this program was
previously calles 'E' (which turned out to be the RAND EDITOR and one of the
synonyms for vi) and 'J' (which turned out to be a language and the name of
another UNIX editor). See below for list of big fixes and new features.

Release 0.0.0 of 'J' (Joe's Editor): This release supersedes all previous
versions which lack a release number. Note that this program was previously
called 'E' but the name has been changed ('E' turns out to be one of the
synonyms for 'vi'). See below for list of bug fixes and new features. The
2 following posts contain the source.
Introduction
'J' is a small screen editor which was designed to be easy to use for
novice users but also to be powerful and complete enough for experienced
users. Several elements of its design are unique innovations. Here is a
copy of the on-line help text to give you a feel for this editor:
GO TO DELETE MISC BLOCK FIND QUOTE WINDOW
^B left ^F right ^D single ^T mode ^KB mark ^KF text ` Ctrl ^KO split
^Z word ^X word ^W >word ^R retype ^KK end ^L next ^\ bit-7 ^KI 1 / all
^A edge ^E edge ^O word< ^KA center ^KC copy ^KL line FILE ^KP up
^P up ^N down ^J >line ^KJ format ^KM move EXIT ^KD save ^KN down
^U page ^V page ^Y line ^KZ shell ^KW save ^KX save ^KR read ^KG grow
^KU top ^KV end ^K- undo ^K, indnt< ^KY kill ^C abort/ ^KT shrink
^G matching ([<{` ^K+ redo ^K. indnt> close window ^KE get file
Other relevent features:
* Extremely small - the XENIX version is only 58K
* Help text can be left on while editing
* Key layout designed to eliminate headaches: ^Q and ^S are not used,
both ^H and DEL are backspace. Also, each user may customize
his key layout by modifying a simple initialization file
* Versions for BSD, HPUX and XENIX 386 are included. A simple tty
driver is also provided to ease porting to other systems
* Currently only VT100/ANSI terminals are supported. If the terminal
has scrolling regions, J uses them. Has well-tuned interruptable
screen update algorithm
* Has: autoindent, word-wrap, overtype/insert, picture mode (right-
arrow makes space past ends of lines), right margin (for paragraph
formatting and center), and magic tabs (the column number of text
after tab stops is preserved when inserting and deleting)
* The cursor column doesn't 'jump' when you move between long and
short lines. Instead the cursor column only jumps when you try to
edit in an invalid place or if picture mode is set, the invalid
place is made real by space filling
* Editor modes can be set depending on file extension
* No line length restrictions. Binary files can be edited without
difficulty
* Long lines are truncated, not wrapped (I.E., the screen scrolls to
the right to get to the truncated parts)
FIXES FOR THIS VERSION
* Shell escape lock-ups are fixed
* Paragraph reformat glitch is fixed
* Cursor update screwynesses fixed for picture mode
* Goto next word/Goto previous word/Delete word left and Delete word
right were made more consistant
NEW FEATURES FOR THIS VERSION
* ~ can be used at file name prompts to expand user home directories
* J now has undelete and redelete (you can go backwards and forewards
through the delete buffer to select which text you want to undelete)
* J now has indent functions. A marked block can be indented more
or less. If you use an indent function outside a marked block, the
lines with the same or greater indent level surrounding the cursor
are marked
* Right margin was added for paragraph format and center line
* Goto matching parenthasis (or [ { ` < )
* ` was made the quote control character key because ^_ is not easy
generate on many keyboard. `` gets `
* tty drivers were rewritten. This made the screen update faster
(now the screen update is instantaneous on 20MHz 386s). Screen
update preempting also works better
THE PLAN
Version 1.0.0 will be a complete rewrite. It should be done sometime
before january. These are my goals for it:
* Block oriented software virtual memory support (for less thrashing
and elimination of file size limits caused by the system's process
size limit)
* MS-DOS support
* X windows support
* Better integration with UNIX: J will be able to process text
through pipes (like vi), will have standard unix regular expressions,
and will be usable as a 'more' program.
* Will be terminal independant and use termcap and terminfo
* Will have a ASCII/HEX dump display mode
* Will have complete program developement support (save&make, next
error/previous error, tags file support)
* Will have a much more powerful scrolling algorithm. I have a
methode which is simpler and faster than even GNU-EMACS' Gosling
algorithm
* All of this will require no changes to the basic keyboard layout-
maybe one more added line of help text for new things
* It will probably have keyboard macros but it won't have much of
an extension language. Maybe in version 2.0.0
* I expect all of this not to add more than 30 or 40% to the size
