Gdb Qt pretty printers

The recently released gdb 7.0 adds a really great feature: python scripting for pretty printers. It makes it really easy to write pretty printers for any class.
Basically it's the same as QtCreator supports, however with a few differences:

• also works in plain gdb on commandline
• no compiled debug-helper library needed
• a gdb-only solution

Example showing a QStringList:

Of course everything can be combined, as seen here:

Currently supported classes are: QString, QByteArray, QList, QMap, QDate, QTime, QDateTime

The code can be found in KDevelop git (gdb plugin uses them by default). For using in cli you need the following in ~/.gdbinit:

python
import sys

sys.path.insert(0, '/home/niko/kdesvn/kde-git/kdevelop/debuggers/gdb/printers')
from qt4 import register_qt4_printers
register_qt4_printers (None)

end
set print pretty 1

Gdb also supports autoloading the pretty printers - they could be included in -dev packages. The merge request that would add it to qt is still pending.

And now I'm off watching an episode of dexter :D
