While debugging in general is an essential part of the devel- opment cycle, debuggers have not themselves evolved over the years as other development tools have through the advancement of Integrated Development Environments. In this free-software research project we propose a way to overcome this problem by introducing, designing and developing a high-level debugging system. High-Level debugging systems are systems that integrate a source - level debugger with other technologies as to extent both the facilities and the interfaces of the debugging cycle. We designed and developed such a sys- tem in a debugging-centric IDE, Misha. Misha, introduces among other things: syntax-aware navigation, data-displaying and editing, reverse ex- ecution, debugging scripting and inter-language evaluation through the integration of its source-level debugger (gdb) with a full- edged source parser, data visualisation tools and other free software technologies.
