Implementation Notes

Based on Qt Debugging Helpers

Note: "raw" gdb pretty printer don't work or at least not well with qtcreator, thus a separate implementation

The Qt debugger python api can be a bit obscure, but these resources helper:

• https://doc.qt.io/qtcreator/creator-debugging-helpers.html
• https://github.com/qt-creator/qt-creator/tree/master/share/qtcreator/debugger
• https://github.com/qt-creator/qt-creator/blob/master/share/qtcreator/debugger/dumper.py

TODO

There seems to be (undocumented) support for plot and image data

• Dumper.py has a putPlotData function that calls putDisplay with plotdata:separate
• The forum post https://forum.qt.io/topic/47370/debug-helper-for-visualizing-images indicates the possibility as well

GDB

Example ~/.gdbinit:

python
import sys
sys.path.insert(0, '/path/to/arcana-pretty-printer/')
from arcana.printers import register_arcana_printers
register_arcana_printers()
end

arcana-pretty-printer's Issues

Wrong degree value for angles.

The angle in radians should be multiplied with 180 / pi.
