Description
XWiki has possibility to scirpt on its pages in Python. Under the hood it's Java Scripting API and Jython that takes care of running this script and returning result to page. Jython has implementation only for standard libraries. That's why Extension Repository Connector - Pypi is created - to be able to import to XWiki other (non-standard) python packages that are hosted on pypi: https://pypi.python.org/pypi
Limitations
Unfortunately there's huge amount of python packages that cannot be installed in XWiki. There are 2 groups of such packages:
- Platform dependent - packages depending on libraries written in C and compiled per given platform e.g. NumPy or SciPy. Jython has limited compatibility with such packages. The future development of extension may take into consideration JyNI (Jython Native Interface) that is a project with aim to enable Jython to use native CPython extensions.
- Packages only for python 3 - that are packages that does not have built version for python 2. Jython version used by XWiki is 2.7.1 that means it's compatible with python packages in version 2.7. (Built package means platform independent Wheel package). To release package on pypi the minimum requirement is to upload sources in 'sdist' package and unfortunately there are quite some packages (but fortunately mainly those less common) that have only 'sdist' (zip) distribution.
Configuration
No configuration needed. The extension after installment connects automatically to main (and practically the only commonly used one) pypi repository which is https://pypi.python.org/pypi
Example
Using Extension Repository Connector - Pypi import requests package. Then create xwiki page with following script:
{{python}}
import requests
r = requests.get(' http://www.mocky.io/v2/59736a8810000022034418c8')
print "Status code is: "
print r.status_code
{{/python}}
The result should be:
Status code is:
200
Prerequisites & Installation Instructions
We recommend using the Extension Manager to install this extension (Make sure that the text "Installable with the Extension Manager" is displayed at the top right location on this page to know if this extension can be installed with the Extension Manager).
You can also use the manual method which involves dropping the JAR file and all its dependencies into the WEB-INF/lib folder and restarting XWiki.
