Can somebody point me towards a Myers diff algorithm in a C project?
I am looking for the following data as diff result:
1. (old) line number
2. (old) column number
3. (new) line number
4. (new) column number.
Need the above info so I can ask my text editor widget to highlight the line and column as to what was added/deleted.
Please reboost for reach :)

I am loving C 17 feature set. It has so many niceties available in std which makes it easy to focus on my product rather than dealing with trivial things.
