New CRiSP Features coming

CRiSP has had an impressive life - starting out as an editor on
MSDOS-3.0. It has been updated to run on all CPUs, operating systems
and platforms - from 16-bit to 80-bit processors (yes, 80, it was ported
to the CRAY-1).

I am just finalising some new features (document map, annotation window),
and a new feature, which some people may find useful - file-saving.

Until recently, you could use CRiSP to view files and explore aspects
of the files and directories, such as cross-referencing. You had
the ability to do infinite-undo (years before anyone else could do the
same), and CRiSP was the first syntax coloring editor on the Unix platform.

But the new feature means that as well as editing your files, you can now
save them. Previously, you could load a file, and make changes. On your
next session, you could make additional changes, but only as long as you
remade the prior sessions edits.

When storing files in source code control systems, and building new
versions of software, having to type in your edits repeatedly, was
a slight problem. (CRiSP has a fast-autorepeat, so this helped enormously
when scrolling to relevant parts of a buffer).

With the "File/Save" feature (which no other editor on the market yet
supports, although I am guessing some will try to copy CRiSP's unique traits),
your files are saved, permanently. When you return to editing, CRiSP
will be able to retrieve the last modified file.

Its taken a while to get this feature working properly, and had me
doing some research into various algorithms which allow for file saving.
(Many of the algorithms are quite technical, and caused me much *grief*
trying to get all permutations working).

The first file-saving implementation is geared around Cellular automata
(otherwise known as "Paper"). With this, you commit your changes to paper,
and when you restart CRiSP, you no longer have to remember what changes
you have made, since the "Paper" copy will let you see immediately. The
advantage of this "cellular" technology is that you can keep older versions
of the files you have saved.
