Windows Full Python Integration

How to replace the Python Interpreter shipped by Scribus 1.5.x for Windows
The Python interpreter shipped with the Windows build of Scribus 1.5.x is limited by the Python at hand when the build is made by the Scribus developer. The Python interpreter runs off a dynamic linked library (DLL) that is shipped with Scribus. Unfortunately, with a DLL, you cannot expand it and integrate various Python packages like you may in a normal Python environment. The DLL is, in essence, frozen. You may want to have a Python Interpreter that can be expanded to include other packages, e.g. the PostgreSQL database package, which is not included in the DLL version. The way to accomplish this is to replace the DLL interpreter with a full Windows installation of Pyton. This gives you a more robust Python environment allowing you to add whatever packages you want.

You can replace the Python interpreter by following the steps below.

First, determine what version of Python has been included with your build of Scribus for Windows:

Main Menu Scripter->Show Console

In top window of Script Console dialog type:

import sys print(sys.version)

Click Script->Run or press F9. The lower window will produce something like:

2.7.8 (default, Jun 30 2014, 16:08:48) [MSC v.1500 64 bit (AMD64)]

This is the version of Python that has been bundled with your Scribus. You want to know this so that you can download the full version and not introduce any compatibility issues between Scribus and the Python you're going to integrate.

At https://www.python.org/download/releases/2.7.8/ there are two choices for either the 32 bit or 64 bit platform. For instance, for the 64 bit platform, there are:

Windows X86-64 MSI Installer (2.7.8) [1] Windows X86-64 MSI program database (2.7.8) [1] You want the Installer. The "program database" is a larger distribution that is meant to include debugging routines. Download the appropriate installer, we'll run it later down below.

Open a DOS console and type "set" to obtain a listing of your default environmental variables. We are interested in the "Path" variable. For instance your Path may have two versions of Python already in it (the ellipsis represents other values not relevant to Python):

Path=...C:\Python32\;C:\Python32\Scripts;...C:\Python27\;C:\Python27\Scripts;...

You do not want to destabilize your current PATH as you may have other software expecting to find whatever version of Python you have in your "Path" and not 2.7.8. So with the caveat in mind, we'll run their installer, but decline to have the installer modify the "Path" environmental variable.

Run the Python installer. Create new top level directory, e.g. C:\Python278 and make sure during the installation that you do *NOT* add python.exe to your path. This is because your system may already be set up for Python 3 or other versions of Python 2 by having their paths be first in your PATH variable. You do not want to destabilize your current system by altering values in your default "Path" value. Instead, we'll set up a special DOS environment which calls Python 2.7.8 when running Scribus.

Here is a batch script that you should copy and place in your Scribus home directory where the main executable Scribus.exe resides, e.g. C:\Program Files\Scribus 1.5.0. Name this batch script: scribus.bat
