Diffract

Kompare is a free software graphical computer application that helps the user to compare two different text files or two directories. Kompare does not actually compute the differences between the compared files itself, but is merely a graphical front end to the command line interface diff utility. However, the colour coding of changed lines makes them very easy to spot. Comparison of files or directories via a graphical interface. Bezier-based connection widget lets you see both source and destination as they really appear. Graphical viewing of patch files in normal, context, unified and diff formats. Graphical interface to commonly used diff command-line options. Easy navigation of multiple-file diffs with the dockable navigation tree. Ability to view plain-text diff output in the embedded viewer. Interactive application of differences. Provides full network transparency.

Pretty Diff is a language-aware code comparison tool, beautifier, minifier, and parser for a variety of languages. Pretty Diff was created to compare code samples for various languages regardless of differences in comments, white space, and other factors. Currently, the project operates by beautifying code and then comparing the beautified product of the code samples. The goal in a future version is to introduce the comparison step directly into the beautifiers between the parse step and the beautification step to become a truly language-aware code comparison and analysis tool. The code comparison mode is the default mode and the only mode to require two code samples. Pretty Diff has progressively moved from community-driven dependencies to custom parsers to accomplish code beautification for a diversity of features and requests. Each of Pretty Diff's beautification libraries has a minify feature.
