Rework Of Center Edit View And Release

I worked on a further edit dialog of the Plone add-on collective.templates today. I added another register to the dialog and reordered some content fields to make it more smooth for the user. You could see some of the register of the template center edit view below.

The register to configure categories, licenses etc.
This register make it possible to provide the allowed file extensions on the website

I published my changes to the Plone add-on and its edit views today. The source code is available from the Plone community Github repository:

Worked Further On Project Edit View Of collective.templates

I created already a new Plone add-on for the upload and management of office template files during the last weeks. I made some further changes to the source code of the add-on during the last days and published new releases of the software.

I reworked the edit view for template projects today. I gave it another structure with register for the different content parts. The dialog is much clearer yet and that will help a contributor to finish the dialog much faster and submit his new project (or edit one of his / her projects).

Here are some screenshots of the dialog and its register:

Register legal
Register category / categories
The register for the upload of the template file

There is another register for the optional upload of template files for different platforms. It looks similar to the above one. There is also a register to upload a screenshot of the template. This screenshot will be shown to the user in the template project view.

The source code of this Plone add-on (collective.templates) is available in the Github repository of the Plone community:

You could download the latest releases from the ‘Cheeseshop’:

New Section Documentation / Howtos

I created a new section for documentation and howtos and added first content about LibreOffice and Plone to it. You could get there my documentation about non-code LibreOffice extensions and a howto about the development of a validation function for file extensions that could be changed by the Plone site-administrator without getting his hands dirty inside the code of a Plone add-on.

You’ll find the new section at

First Release Of The New Plone Add-On collective.addons

I worked on a new Plone add-on to manage and to provide software product add-ons during the last weeks. This new add-on, named collective.addons, runs on Plone 5.2 and Python 3. It has currently a localization in German language too, but it would be easy to add further localizations to the add-on later. It needs only the creation of a subdirectory inside the locales subdirectory and a new po-file for the further language.

I created a first alpha release of the new collective.addons Plone add-on today and uploaded it to the ‘Cheeseshop’ ( You can find it at:

The source code of the new Plone add-on is available at the Plone community repository at Github:

Worked On Plone Add-on Clamav

I created a new Plone 5.2 and Python 3.6 buildout to migrate the Plone add-on collective.clamav to this Plone version and Python 3. I had to change the ‘import Globals’ and the use of ‘Globals’ according to the information on the upgrading Plone 5.1 to 5.2 website ( I also changed the ‘implements’ statement to the ‘@implementer’ decorator.

I had to remove the backward compatibility to the AT content types. It works with the new (Dexterity) Plone content types only. I tested it successful  with the Eicar virus test signatur.

Working With Plone 5.2 On Python 3

I’m currently working on a new Plone add-on to manage the upload and distribution of product add-ons / extensions. I develop this add-on from scratch with my experience from other Plone add-ons which I created within a Python 2 Plone environment.

The development of the new add-on is done inside an environment of the latest Plone version (5.2) in combination with Python 3 (3.6 in this case). I started the development using Python 3 because the support for Python 2 stopps in less than five month and I thought it is not usefull to create a new add-on within an nearly outdated Python environment.

You could get the calculation of the Python 2  version retirement at

It’s time for projects using Python 2 to think about the migration to Python 3 soon.

A New Release 0.36 For The LibreOffice Extension Center Plone Add-on

I made a bunch of changes to the Plone add-on which drives the current LibreOffice extensions website during the last weeks. I especially made it easy to enter the file extensions for extension, image and documentation files and change them if needed. This is possible without the need of any programming skills. I had to create new validators for this purpose and replace the old ones with them.

The new release of the Plone add-on ‘tdf.templateuploadcenter’ is available via the ‘Cheeseshop’ ( yet:

It is version 0.36 and you could download it from there or much easier include it into your buildout script.

A Further Release Of The Plone Add-On For The LibreOffice Templates Website

I made some changes and fixes on the Plone add-on that drives the current LibreOffice templates website. This changes makes it possible for a site administrator to set allowed file extensions on the site within the template center content type (without the need to touch the source code).

I created a release of this Plone add-on and published it today on the Cheeseshop ( (release 0.31):

New Release Of tdf.templateuploadcenter

I worked on some further improvements of the Plone addon tdf.templateuploadcenter. A site administrator is able to edit the allowed image and template file extensions. Thus I wrote a new validator for this file extensions. I created a field to inform contributors about the currently allowed file extensions (with dynamic content).

The add-on provides not only projects with releases but also small projects where the template files are uploaded to the small project content type directly.

Today I made a new release of this Plone add-on, which drives the current LibreOffice templates website. The Plone add-on and its release are published as Free Software under the GPL-2 (General Public License version 2):
