jGRASP integrates the Control Structure Diagram (CSD) seamlessly and unobtrusively into source-code editing for Java, C, C++, Objective-C, Ada, and VHDL. The CSD is a control flow and data structure diagram that fits into the space normally taken by indentation in source code. Its intention is to improve the readability of source code. The CSD also enables source code folding in a meaningful way, based on code structures. jGRASP provides lots of editing features, an integrated Java debugger, UML dependency diagrams for Java, configurable colors and font size, and click-to-error for compile and runtime (Java stack dumps) errors.
GPS is a free software multi-platform and multi-language integrated development environment (IDE). It provides a wide range of tools integrated together, and features particularly powerful source navigation capabilities. GPS also integrates GVD, the GNU Visual Debugger, and replaces it.
Structure101 is a tool to understand, measure, and control software structure. It allows you to see exactly how your high-level components depend on each other and why. You can use it to find out immediately when your architecture is accidentally changed by code-level changes at the coal-face. It can help you control structural complexity, since it can measure the complexity of methods, classes, and packages and warn you when given limits are exceeded. It can also discover the locations of productivity-killing package dependency cycles.
QtAda is an Ada2005 language binding to the Qt libraries and a set of useful tools. It allows you to easily create powerful cross-platform graphical user interfaces completely on Ada 2005. QtAda applications use the native look and feel on every supported platform. It also allows you to develop your own widgets and integrate them into the Qt Designer for high speed visual GUI development. It uses a native thread-safe signal/slot mechanism and provides full transparent integration with Ada tasks.
