's' from Webb Miller's _A Software Tools Sampler_ is an exhaustively
documented sort-of-stripped-down vi. Admittedly it's a little tricky to
get your hands on the source document (I got it from interlibrary loan back
at the end of the Before Times, and archive.org lets you check it out for a
limited time, but there may be a waitlist).
It's interesting in that it's not just studying the source to see how it
works, but an actual (large) chapter of a book where he steps through the
construction of the individual functions and their keybindings.

I'd use SQLite nowadays, because it takes
extraordinary care to make
sure that no data is lost short of disk failure. It is considerably
more robust than the underlying filesystem, and runs embedded in its
process. It also means you can readily carry about arbitrary data in
additional columns; for example, you could make line marks persistent,
including dot.
Good point; thanks. I'd forgotten about SQLite... I doubt if I'll be
writing a new editor any time soon though (VI works just fine) but was
planning on incorporating it in a project I'm working on.
