diff

I'm looking for some tool to give me a recursive diff of two arrays. What I envision is a web page with two color-coded tree-structures. On each tree, green are parts of the array which match in both arrays, and red is for parts of each that don't match the other. Something like the output of dBug I have some code that gives me a nested array to populate a report. I'm developing a new method that should be faster, but I need to test the values and also the structure, to make sure it gives output identical to the old method. Is there something out there that I can use? Or do I need to write

In a project where some of the files contains ^M as newline separators. Diffing these files are apparently impossible, since git-diff sees it as the entire file is just a single line. How does one diff with the previous version? Is there an option like "treat ^M as newline when diffing" ? prompt> git-diff "HEAD^" -- MyFile.as diff --git a/myproject/MyFile.as b/myproject/MyFile.as index be78321..a393ba3 100644 --- a/myproject/MyFile.cpp +++ b/myproject/MyFile.cpp @@ -1 +1 @@ -<U+FEFF>import flash.events.MouseEvent;^Mimport mx.controls.*;^Mimport mx.utils.Delegate \ No newline at end of file +<U

I've been looking like crazy for an explanation of a diff algorithm that works and is efficient. The closest I got is this link to RFC 3284 (from several Eric Sink blog posts), which describes in perfectly understandable terms the data format in which the diff results are stored. However, it has no mention whatsoever as to how a program would reach these results while doing a diff. I'm trying to research this out of personal curiosity, because I'm sure there must be tradeoffs when implementing a diff algorithm, which are pretty clear sometimes when you look at diffs and wonder "why did the

I need to perform Diffs between Java strings. I would like to be able to rebuild a string using the original string and diff versions. Has anyone done this in Java? What library do you use? String a1; // This can be a long text String a2; // ej. above text with spelling corrections String a3; // ej. above text with spelling corrections and an additional sentence Diff diff = new Diff(); String differences_a1_a2 = Diff.getDifferences(a,changed_a); String differences_a2_a3 = Diff.getDifferences(a,changed_a); String[] diffs = new String[]{a,differences_a1_a2,differences_a2_a3}; String new_a3 =
