A new state "replace"

[jactive]

This is a feature request rather than a issue. A new state "replace" is require.
See https://github.com/reviewboard/reviewboard/blob/master/reviewboard/diffviewer/myersdiff.py#L123

Could you provide some details on what this would do? I'm not sure how this concept to integrate with unified diffs, etc.

Thanks for your concern.
The output of jsdiff includes removed, added and unchanged state to describe the kinds of change in the text. For example, original text: aab, new text: aac. In diffChars mode, jsdiff will return [{value: "aa"}, {value: "b", remove: true}, {value: "c", added: true}]. In general purpose, it is good enough. But I want the result to be more useful. I want to know that the b in the original text "aab" is replaced with c in the new text "aac".

If it is not clear enough, the output of myersdiff.py maybe helpful. Take the previous example. The outputs of myersdiff.py are [('equal', 0, 2, 0, 2), ('replace', 2, 3, 2, 3)]. To print this result, please download the python file by the link in my first post. Paste the two line codes below at the bottom of the file myersdiff.py. Please make sure there is no leading space in the two additional line.

differ = MyersDiffer("aab", "aac")
print list(differ.get_opcodes())

I'm looking for something like that.
A working example of this could be: http://cemerick.github.io/jsdifflib/demo.html
