DroneKit-Python apps can be debugged in the same way as any other standalone Python scripts. The sections below outline a few methods.
The Python Debugger - pdb can be used to debug DroneKit-Python apps.
The command below can be used to run a script in debug mode:
python -m pdb my_dronekit_script.py
You can also instrument your code to invoke the debugger at a certain point. To do this
add set-trace() at the point where you want to break execution:
# Connect to the Vehicle on udp at 127.0.0.1:14550
vehicle = connect('127.0.0.1:14550', wait_ready=True)
import pdb; pdb.set_trace()
print "Global Location: %s" % vehicle.location.global_frame
The available debugger commands are listed here.
If you prefer a IDE like debug you can use pudb - A full-screen, console-based Python debugger.
pip install pudb
To start debugging, simply insert:
from pudb import set_trace; set_trace()
Insert either of these snippets into the piece of code you want to debug, or run the entire script with:
pudb my-script.py
The simplest and most common method of debugging is to manually add debug/print statements to the source.
# Connect to the Vehicle on udp at 127.0.0.1:14550
vehicle = connect('127.0.0.1:14550', wait_ready=True)
# print out debug information
print "Global Location: %s" % vehicle.location.global_frame
In addition to printing DroneKit variables, Python provides numerous inbuilt and add-on modules/methods for inspecting code (e.g. dir(), traceback, etc.)
There is no reason you should not be able to straightforwardly use other popular Python IDEs including IDLE and Eclipse.
