HOW-TO:Debug Python Scripts with Eclipse

Here is a method you can adopt in order to use the Eclipse (multi-platforms) remote debugger with your Python scripts/plugin.

Aug 28, 2013 Now, go back to PhpStorm or your IDE of choice and set a 'breakpoint'. Breakpoints are like markers on a line which tell the debugger to halt the execution of the script at that breakpoint. In PhpStorm, you can simply add breakpoints by clicking the space next to. Enhanced Class Decompiler integrates JD, Jad, FernFlower, CFR, Procyon seamlessly with Eclipse and allows Java developers to debug class files without source code directly. It also integrates with the eclipse class editor, m2e plugin, supports Javadoc, reference search, library source attaching, byte code view and the syntax of JDK8 lambda expression.

Note: Follow this link Debugging Python Scripts on Linux with WinPDB for more information if you prefer to use WinPDB instead.

Note: The information provided herein is also applicable to user with Aptana Studio 3 installation which come pre-installed with pydev. For this case, you can skip to Configure Pydev and Eclipse after the Aptana Studio 3 installation.

2Prepare and Setup Eclipse
- 2.3Configure Pydev and Eclipse
3Create a Python script/plugin for XBMC in Eclipse
- 3.4Add Pydev Python source code (pysrc) to XBMC
  - 3.4.4Copy pysrc in XBMC Python install

1 Prerequisite

Any platform able to run Eclipse IDE (Windows 32bit-64bit, Mac Carbon 32bit-64bit, Mac Cocoa 32bit-64bit, Linux 32bit-64bit): it is the platform from where you will run the debugger IDE
Python interpreter 2.4 (use the same version as XBMC or version <= 2.7 ) install on the machine running Eclipse
Any platform running XBMC (Xbox, Linux, MACOSX, Windows): it is the platform running Python scripts/plugin connecting with the remote debugger.

XBMC installed on Ubuntu (should work just fine on Windows and Mac too)

Pydev plugin for Eclipse IDE: Pydev is a Python IDE for Eclipse, which may be used in Python, Jython and IronPython development.

2 Prepare and Setup Eclipse

2.1 Install Eclipse

Download Eclipse IDE and install it

Note: in our example Eclipse Galileo (3.5.1) is used

2.2 Install Pydev in Eclipse

In Eclipse go in: Help -> Install New Software..
Click on the Add button and add Pydev website as a source: http://pydev.org/updates
You will see the window below:

Check PyDev box and follow the steps in order to install PyDev

Note: in our example PyDev 1.5.5

2.3 Configure Pydev and Eclipse

2.3.1 Add Python Interpreter Path

Go in Window -> Preferences
Pydev then Interpreter - Python
Click on button New..
In the new prompt, enter the Interpreter Name: Python, and Browse for your Python Interpreter 2.4 python.exe file and select it. After that you should see something like this:

This will help in order to have Python code completion (except for XBMC modules)

2.3.2 Add Pydev view to Eclipse

On the top right corner click on the View button on select Others

Select Pydev then OK, a PyDev View Button should be now available on the top right corner

Use this view for your developments in Python for XBMC

2.3.3 Add Pydev Start/Stop debug server buttons

In the menu bar select Window -> Customize perspective.., a window Customize Perspective - PyDev will open
Select Command Groups Availability Tab
Check Pydev Debug box and OK
You should see 2 new buttons in your toolbar:

2.3.4 Setting the remote debugger port (optional)

If you do not want to use the default port (usually 5678) you can set it up:

Go to Window -> Preferences
Pydev then Debug you can define here the port and the timeout you want

2.3.5 Setting up Predefined Completions (optional)

Many developers are accustom to using predefined completions when writing their code (eg. type-ahead). The standard Python completions are enabled by default when using these instructions, but the standard XBMC components will not be recognized appropriately (xbmc, xbmcgui, xbmcplugin, etc).

In order to overcome this, you can run the PyDev Predefined Completions Creator addon and setup Eclipse to reference this file:

Download the 'PyDev Predefined Completions Creator' Addon (eg. System > Settings > Addons > XBMC.org > Program Add-Ons)
Navigate to the newly installed Addon (eg. Programs from the home screen)
Open the context menu for newly installed addon and select 'Add-on Settings'
Set the location to save the help docs to and save the new settings (This can be anywhere on your system - we'll configure it in Eclipse later)
Select the add-on to run it (the addon should run and close quickly)
Open Eclipse and select Window > Preferences > PyDev > Interpreter - Python
From the 'Predefined' tab, click the new button and select the folder you created in the step above
Press Apply / OK to ensure the changes are saved

3 Create a Python script/plugin for XBMC in Eclipse

3.1 Create a new PyDev Project

Fusion 360 mac torrent. Most of the time when you are doing development, likely that you are running XBMC and Eclipse on the same platform; (The installed debugger described in this article actually can also work with a remote XBMC).<br>Let's say you already have scripts installed in XBMC script folder that you want to create a new PyDev project e.g.

With myscript1 & myscript2 being sub-directories of C:XBMCaddons each containing the Default.py scripts.<br>First you need to define the Python project workspace:

File -> Switch Workspace -> Other..
Browse to the parent directory of your script module i.e. C:XBMCaddons in this example, select and OK

Then proceed to create the Python project:

File -> New -> PyDev Project

OR select below in case PyDev Project is not displayed

File -> New -> Others; and Select Pydev then PyDev Project; Click Next
Enter the name of your project e.g. xbmc_addons
Uncheck option Use Default
Browse to the directory of your scripts and select i.e. C:XBMCaddons.
Set Python' as Project Type
Select 2.4 (XBMC Python version) for the grammar
Select Don't configure PYTHONPATH (to be done manually later on)
Click on Finish button

3.2 Set the Python Path

Right click on your new project and select Properties
Select PyDev - PYTHONPATH and click on Add source folder
Select the source directory of your script, /xbmc_addons in our example

3.3 Import File System

Assuming you want to add in all the directories under C:XBMCaddons

Right click on your new project and select Import..
Select General and click on File System; then Next
Browse to the source directory of your script (or plugin) e.g. C:XBMCaddons
Check the directory and files to be added
Select Into folder: xbmc_addons
Select Options <<Advanced Create links in workspace
Uncheck both the options i.e. Create virtual folders & Create link locations relative to;..
Click on Finish button

Your source code is now recognized by Eclipse and you will have access to neat functionality such as code completion, link between source files, etc.

3.4 Add Pydev Python source code (pysrc) to XBMC

XBMC needs to know where to find the PyDev remote python source file in order to communicate with the remote debugger of Eclipse.

3.4.1 Identify where PyDev remote debugger Python files are

In later versions, you need to have started the debug server from Eclipse at least once for the following folder to show up.

Python source files should be in you Eclipse installation directory:

In our case we use PyDev 1.5.5. With newer versions of PyDev, the directory structure changed.

Look for org.python.pydev.debug (not core)

Instructions for Linux users:

Extended content
In new Eclipse versions on Linux, the standard eclipse installation (/usr/share/eclipse/plugins) does not contain the pydev files any more.The easiest solution is to install the pydevd-addon. To access this from your addon, your addon.xml has to contain `<import addon='script.module.pydevd' version='3.4.1'/>`.

3.4.2 Modify PyDev source in order to support XBMC paths

The pysrc code that came with Eclipse-pydev does not support XBMC paths (special://.. or Q:/..) and the module would not find them making it impossible to insert breakpoints in such files.

In order to add the support of XBMC paths, you will need to do a simple modification to the file pydevd_file_utils.py consisting on adding a line to each procedure that had a filename parameter (4 procedures in total). Add a line like

The other three procedures are:

def _NormFile(filename):
def NormFileToServer(filename):
def NormFileToClient(filename):

of course you need the import directive at the top of the file:

at the beginning of the module..

3.4.3 Choose how XBMC will refer to Pydev debugging module

You have 3 options as below:

Option 1 - Refer from our python script directly the directory where pysrc is installed
Option 2 - Copy pysrc in our script directory and refer it from our script
Option 3 - Copy pysrc in XBMC Python install
Option 4 - Use the pydev from the pydevd-addon

I am only going to show you the steps for Option 3:

3.4.4 Copy pysrc in XBMC Python install

3.4.4.1 Option 3: (Suggested for Windows users)

Copy the content of pysrc to:

Add an empty __init__.py file in it

3.4.4.2 Option 4: (Suggested for Linux users)

Use the pydevd-addon as described above. No action necessary. Option 3 does not work on Linux, because /usr/share/kodi/system/python/Lib is ignored.

3.5 Add to your python script the code for remote debug

At the beginning of you Python script/plugin (usually Default.py) add the following code:

If this doesn't work and you are still getting the PYTHONPATH error you can try to:

Replace:

in the code snippet above with:

In the case you have changed the default port you can replace the line with pydevd.settrace by this one:

Use REMOTE_DBG in order to activate or not the remote debugging
port specifies the listening port number use between the client and the server
Replace localhost by an IP address if XBMC and Eclipse are on 2 different machines
stdoutToServer and stderrToServer redirect stdout and stderr to eclipse console, you won't have to open xbmc.log file

3.6 Run

Go in Debug view (Eclipse: / Debug ) and press on the start server button:

You will see in the console logs like:

Start XBMC and run your script/plugin, you will see it as 'Running' but paused

In Eclipse (Debug View) click on the Resume button (or F8), then you will see the program running in XBMC

You are now fully set up: You can set break-point, watch on variables, run step by step etc

Enjoy!
