I want to provide a diff report for a non regression test. My program is Java based but I did not found any API filling my needs.
So I'm using an external tool (CSDiff) that take 2 files as arguments and return an HTML report. That's nice and easy to setup.
Now the only problem I have is that the HTML report needs some tweaks to be used and I am messing around with the report, trying to transform it into something different (hidding some parts, changing the style, ...)
Does someone know a diff tools that has a powerful command line support, allowing custom report to be generated ? Nice report options would be 2 panes view, regexp filtering, easy styling options... something like the vim diff view in html would be great.
I've already read stuff about diff tools in stackoverflow but I don't find the stuff I'm looking for.

- Free diff tool that is configurable?
- Need a Java and Javascript diff tool written in Java
Many Thanks
I would recommend google-diff-match-patch. This provides HTML or the basic diff components which you could style and transform yourself.
Pretty Diff provides an HTML report either on screen in a web browser or as HTML formatted text that can be saved as an HTML file.
I don't know such library from top of my head but if Google search doesn't bring anything relevant back, I would take a look at Eclipse sources. Eclipse has very good text diff tool which you might be able to reuse, unless it's tied up pretty badly to their UI stuff, which I hope is not the case.
