Retrieve information from to safely and easily pin your egg versions

Project Description


Retrieve information from to safely and easily pin your egg versions.


It is a common practice, for Plone buildouts, to extend online configuration files that declare known good working versions. Those external resources can, in turn, extend other remote resources.

This means that your buildout relies on the assumption that the all those external resources are available. If they are not buildout will fail: a network problem can really turn out in a catastrophe!

This already happened. Luckily there are workarounds to solve this issue:

Another (minor) issue with this approach is that you have to wait for the resources to be fetched before starting.

Some other times, you may not want to include network resources, e.g. because your customer network will not easily allow you to fetch them.

Given that I don’t want to cross my finger and wait for those resources to be retrieved on the net, I started including all those externals known good working versions in a file.

It is tedious to do it by hand, because you have to fetch and merge some files in the correct order, so I wrote the ploneversions script.

I hope you will enjoy it!


You can install rt.ploneversions with pip or easy_install:

pip install rt.ploneversions


Launch the ploneversions script passing a valid Plone version.

Example output (with some ellipses):

$ ploneversions 4.3-latest
## = 3.5.10
zope.rdb = 3.5.0

zope.annotation = 3.5.0
zope.kgs = 1.2.0

Zope2 = 2.13.21
zope.testbrowser = 3.11.1

docutils = 0.9.1
zc.relation = 1.0

You may want to redirect this output to a file, e.g.:

$ ploneversions 4.3-latest > versions.cfg

and add this file to your buildout.
