I agree. Start by identifying the editing operations that the data
structure must support, no matter how it is implemented. Those
operations will form the API for your data engine, and no other part of
the editor should be written in a way that cares about the internals of
that engine.
Basically you can work with a single operation: Replace range
replace_buffer_range(buffer, start, end, new_content);
This provides insert (start == end), erase (new_content is empty),
and replace without needing to do erase then insert.
Very cool!
But you'll need a couple of other basic operations too:
* read the text within a given range
* search, i.e. set 'start' and 'end' given a regex. (You might want to
have this return a set of ranges rather than just one.)
