What's the possibility of getting it into the Sword API? (I know we
are all busy and I am not a C++ coder anymore. It's been too long.)
There's a little complexity in that wdiff is a frontend to diff. (It
literally runs an instance of whatever version of diff is in the path
and processes its output.) So we would need to incorporate both wdiff
and diff, changing the stdio piping to something that can be handled
internally. There might be some complication if the code itself is
especially old (or old in style) C. But this should all be pretty
easily handled.
There's one other issue, but I'll cover that in another email....
Someone has ported the GNU diff algorithm to Java (see
http://www.bmsi.com/java/Diff.java)
It is written as the diff of two arrays.
I compared the code against analyze.c in GNU's diffutils and it looks
like a straightforward port.
I think it would be trivial to port it to C++.
Appropriately, it is licensed with the GPL license.
