This version of the STEVIE sources and executable requires the GNO
|
|
multitasking environment, because STEVIE uses some GNO system calls
|
|
to enable it to work more like the real 'VI'.
|
|
|
|
This archive contains only the Stevie executable. Look for the source
|
|
archive in the same place you got this one.
|
|
|
|
This version of STEVIE has been modified to use the termcap library,
|
|
allowing STEVIE to operate on a wide range of terminal types, including
|
|
gno, vt100, proterm special, etc.
|
|
Apple IIgs BBS's now have a full-screen editor for posts, etc.
|
|
|
|
The termcap file is _not_ provided; look in the same place you got
|
|
Stevie for the latest termcap file.
|
|
The termcap file should be placed in your $home directory
|
|
(see your gshrc file for where $home is) or in directory 31:etc
|
|
(choose an existing directory or create a new one, and set prefix 31
|
|
in your gshrc).
|
|
|
|
It shouldn't be too hard to modify STEVIE to work under ORCA, but considering
|
|
all the other advantages of GNO, and the growing library of software that
|
|
requires it, I recommend you purchase GNO immediately (ok, so this is a plug).

CHANGES
|
|
|
|
2/3/94
|
|
Fixed a MAJOR buffer overflow bug that was causing Stevie to barf a lot
|
|
when doing delete lines, undos, etc. Basically, my screen output buffering
|
|
routines were not checking for the end of buffer.
|
|
|
|
7/20/92
|
|
Added auto screen-redraw when Stevie is unsuspended from the shell
|
|
|
|
Fixed termcap support again- we forgot to call tputs in _one_
|
|
location, causing cursor goto's to have a '5' placed in front
|
|
of them. Also took care of the problem where Stevie wouldn't
|
|
scroll with vt100 (you need a new termcap file dated 7/19/92 or
|
|
later for this).
|
|
|
|
I now use one of GNO's TextTools features so I know the difference
|
|
between right-arrow and control-U. Happy, Matt? :-)
|
|
|
|
Sped up screen output slightly by doing buffering and going directly
|
|
through the GNO console rather than TextTools.
|
|
|
|
Claimed Stevie as our own; we won't bother to keep ours current with
|
|
the original because the authors cannot be located.
|
|
|
|
Started optimizing some stuff; done mainly for space considerations
|
|
right now (i.e. only turning off stack 'protection')
|
|
|
|
Sped up file saves ~400% by assembly-izing and using a large, custom
|
|
file I/O buffer. (normal.c: 8 seconds to less than 2)
|
|
|
|
Sped up file loads ~60-80% by using a large, custom file I/O buffer.
|
|
any further load speed increases will require changing Stevie's memory
|
|
allocation scheme-a proposition that will probably mean rewriting most
|
|
of the code in Stevie. (normal.c: 10 seconds to 6)
|
|
|
|
Typing the suspend character while in insert or replace mode adds
|
|
that character to the buffer, rather than suspending Stevie. (e.g.
|
|
typing '^Z' will insert a '^Z'.)
|
|
|
|
4/21/92
|
|
|
|
Fixed termcap support- now correctly calls termcap routine 'tputs'
|
|
to output all term control codes. Thus, Stevie now works with the
|
|
VT100 termcap entry (which has special termcap delay codes, etc in it)
