A user can start debugging a program with Nemiver either directly from the command line by typing

nemiver    ... 

or by launching Nemiver first and then using its graphical dialogs to launch the program you want to debug.

Once the program to be debugged is launched, Nemiver automatically sets a breakpoint in its main function. Once the program is stopped in the main function, the user is free to set breakpoints, inspect variables, single step, resume the execution of the inferior, etc.


Nemiver stores on disk some basic information about a debugging session so that it can easily be resumed later. Whenever debugging is started, a new session is created automatically unless it is explicitly requested to resume an existing session. On exit, the session will automatically be saved. Information saved with a session includes breakpoints, program arguments, working directory path, environment variables, etc. Additionally, the current session can be saved to disk on demand.


Nemiver is a bit more than just a simple GUI debugger. It is actually a platform which can be extended with plug-ins based on dynamically loaded modules. The libnemivercommon library provides the basic functionality for loading dynamic modules and enabling the plug-in architecture of Nemiver allowing the program to be extended using additional plugins, and even entirely new perspectives for the nemiver workbench. Currently, only the debugging perspective is provided, but others could be added in the future (e.g. a perspective for profiling tools such as OProfile, Valgrind / Massif, etc.). Nemiver also provides an event-based debugger library (which currently features a gdb back end, but others could be added in the future) that could be re-used by other projects seeking to implement a debugger as a part of an IDE, for example.


Nemiver is written in C++, and heavily relies on many components of the GNOME platform, such as Gtkmm.
