SourceHighlightIDE is an IDE for GNU Source-highlight. When given a source file, Source-highlight produces a document with syntax highlighting. In particular, SourceHighlightIDE is useful when you have to develop a new language definition file for Source-highlight. Source-highlight reads source language specifications dynamically, so it can be easily extended for handling new languages without recompiling the sources. SourceHighlightIDE is also useful when modifying or debugging an existing language definition file.
Source Navigator NG is based upon Red Hat's Source Navigator. Source Navigator is a source code analysis tool. With it, you can edit your source code, display relationships between classes and functions and members, and display call trees. You can navigate your source code and easily get to declarations or implementations of functions, variables, and macros, which helps you discover and map unknown source code for enhancement or maintenance tasks. Source Navigator NG tries to improve usability and performance.
