problem description
now there is such a requirement:
there is a software, there are several versions of this software, and there is little difference between these versions.
that is, most of the code in these versions is the same, and a small part of the code in
is different.
the point is:
has a problem with the public parts of these programs.
can I have a way to modify
only once, and
to make all versions change
but keep the original version different?
the platform version of the problem and what methods you have tried
(1) extraction of common parts is a big problem.
finally, I found that my needs are a little contradictory, but I still want to discuss it with you.
Thank you
