Archive:Debug python scripts with WinPDB

You can easily debug python scripts running inside XBMC in a few simple steps!

Requirements

• XBMC installed on Linux or Windows (should also work fine on Mac)
• Install WinPDB. Download the binary installer for Windows or Mac, use this command for Linux:

  $ sudo apt-get install winpdb

• On Mac, Windows and some Linux distros you will also need to install wxPython. Always use the 32-bit version.

Create a symlink for the debugger

How to make a symlink in Linux

• Assuming your script's name is Foo

$ cd /home/<user>/.xbmc/scripts/Foo
$ ln -s `find /usr/lib/pymodules -name rpdb2.py`

How to make a symlink in Windows

• Get and open the program Directory Linker
• For Link Location: point to your addon folder in XBMC, and then add winpdb.py on the end of the path. For example:

C:\Program Files (x86)\XBMC\addons\plugin.video.icefilms\winpdb.py

• For Link To: point to where the original winpdp.py file can be found. (Should be with your other Python modules) For example:

C:\Python27\Scripts\winpdb.py

• Click Go! button

Modify your script to enable debugger

• Edit /home/<user>/.xbmc/scripts/Foo/default.py and add the following code to the top

import rpdb2 
rpdb2.start_embedded_debugger('pw')

Start debugging session

• From within XBMC, start your script (it will appear to sit there and hang)
• In WinPDB, select File->Password and enter "pw" (no quotes)
• Select File->Attach. You should see your running script in the list box along with its PID and filename.
• Select your script and click OK. The debugger is now attached to your script.
