How to diff with two files by JGit without creating repo?

Question

When I use JGit to diff with two files, I must create a repo first. But in Git, I only need to use command git diff --no-index 1.txt 2.txt.

Is there a way to use diff in JGit without creating repo?

in other words : How do I do the equivalent of “git diff --no-index file1 file2” with jgit? when using “git diff --no-index file1 file2”, it doesn't need a git repository — eabiao, Oct 21 '12 at 04:40

thank you! I have solved this question!

method is below

private static String getDiff(String file1, String file2) {
    OutputStream out = new ByteArrayOutputStream();
    try {
        RawText rt1 = new RawText(new File(file1));
        RawText rt2 = new RawText(new File(file2));
        EditList diffList = new EditList();
        diffList.addAll(differ.diff(COMP, rt1, rt2));
        new DiffFormatter(out).format(diffList, rt1, rt2);
    } catch (IOException e) {
        e.printStackTrace();
    }
    return out.toString();
}

thank you for your help!

And what is `differ` in this snippet? – zedoo Feb 12 '14 at 13:00
`new HistogramDiff().diff(RawTextComparator.DEFAULT, rt1, rt2)` does the trick – yeahwhat Apr 12 '16 at 09:38

Hm I don't understand the question exactly, but maybe you are looking for something like gitective which makes it with the help of his BlobUtils "Diff two files" to a more easy task.
