Nemiver 0.4.0

Nemiver is an project to write a standalone graphical debugger that integrates
well in the GNOME desktop environment. The project currently features a backend which uses the well known GNU Debugger gdb.

General

- In addition to the toolbar buttons, you can toggle breakpoints simply by clicking in the margin on the line you want to break on.
- hovering over a variable name for longer than 1 second should show its value as a tooltip window if the variable is in scope

Sessions

Nemiver uses an sqlite database to store basic information about a debugging
session so you can resume where you left off last time. Whenever you start
debugging, a new session is created for you automatically (unless you explicitly
request to resume an existing session).

On exit, your session will automatically be saved. Information saved with your session includes breakpoints, program arguments, working directory path, environment variables, etc. Additionally, you can save the current session to the database on demand by selecting File > Save Session to Disk.

To resume a previously saved debugging session, you can either specify the
session ID to the --executesession command line option or select File > Saved
Sessions... > [select session] from the User interface.

Source Directories

Some versions of the GDB debugger dont provide full pathname information for breakpoints, etc. In this case, you may need to specify which directories to search for source files. These can be specified by manually adding source directories in the Preferences dialog. In the future there will be a more explicit prompt asking the user to locate the requested file when nemiver cant determine the absolute path of a file on its own.

Extending Nemiver

Nemiver is a bit more than just a simple GUI debugger. It is actually a platform which can be extended with plugins and dynamically loaded modules. The libnemivercommon library provides the basic functionality for loading dynamic modules and enabling the plugin architecture of Nemiver. You can create additional plugins for nemiver, and you can even create 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 backend, 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.
