Diffract

DiffDog includes powerful capabilities that let you compare and merge any type of text-based file, with support for Unicode, ASCII, MBCS, and any other file formats. DiffDog allows bi-directional merging as well as direct editing of both compared files. DiffDog automatically creates a backup of each file, allowing you to re-load the original file from the server or disk at any time should you need to start over. The XML differencing and editing features in DiffDog draw on Altova’s legacy as creator of XMLSpy, the world’s leading XML development. With robust features such as well-formedness and validation checking, code completion, DTD/schema based entry helpers, and more, DiffDog is a must-have differencing utility for Web and software developers working with XML.

DirDiff started as a tool to check two copies of files in separate directories, either by date or by a different modified date. From there, we had a go at building our own text-diff. Other diff's show the content of both files, and thus show the content that is equal twice. Sounds like a lot of wasted screen-space, so we show a single 'flow' and the different parts in different colors. Yes, we know we might have got green and red reversed, but since we use diff primarily to check what we've changed before commit, We like them to show up in red because it draws attention. It can also show the structure of XML documents in a tree view. If you configure the usual attribute names that holds identifying values, it will use those to show the relevant changes. If you're using TortoiseSVN, it turns out to be a good alternative diff to use with TortoiseSVN, open the settings and enter the command provided in our site for the external Diff Viewer.
