[Tkdiff-discuss] My patch for inline diff highlighting

[Michael D. B. <be...@ya...>]

I made some patches to support inline diff highlighting.
I moved the patches I made to the 3.09 version from
accurev.com to the latest version in cvs (3.09 + the
macosx aqua changes?). Attached is my patched version.

I implemented two algorithms for performing inline diffs:

(1) byte-by-byte - good for large text files with diffs
corresponding to column numbers. I use this for
detailed comparison of images represented as text files.

(2) recursive pattern matching based on
Ratcliff/Obershelp. This finds the longest common
substring, assumes this is an anchor, and recursively
repeats for the remaining left and right substrings. I
revised it a couple of times to make it more efficient,
and it is not too bad.

This required adding to, and changing, the color/font
scheme in the text windows. I also added some gui
changes to support the enabling of either inline diff
algorithm.

I posted the patch to the sourceforge tkdiff patches area ...

Feedback?

Mike.
