Collabora’s LibreOffice development experts are supporting students for GSoC 2020

Collabora developers are mentoring students during this year’s Google Summer of Code

Google Summer of Code is an amazing, international program encouraging the participation of university students in open source software development. It enables students to independently gain practical experience on concrete projects and matches them with experienced developers. This year a record number of almost 1200 students is taking part in the sponsored projects. Collabora is always delighted to support GSoC projects: some of our experienced developers are mentoring the students: guiding them in the code, encouraging them, and supporting the growth of their skills.

Collabora developers at GSoC 2020

Also for this year’s GSoC several students are being mentored by Collabora Productivity team members. Tomaž Vajngerl, Muhammet Kara, Miklos Vajna, Mike Kaganski, and Michael Meeks are assisting the work on several projects around LibreOffice. And our companies involvement is not just limited to that. Andrej Shadura, a developer from our parent company Collabora, is in charge of various projects around the Debian operating system. Collabora’s support of these Google Summer of Code reflects our commitment to open source software and is also a matter of personal attachment. Several of today’s Collaborans like Elie Tournier and Rohan Garg have successfully participated in the GSoC program in the past. So have the current mentors Muhammet Kara, Miklos Vajna, and Pranam Lashkari from Collabora Productivity team.

A success story – development camps in Turkey

The successful application of no less than six LibreOffice office projects for this year’s Summer of Code would not be fully told without mentioning some previous happenings in winter. Collabora Productivity had sponsored the LibreOffice Developer Bootcamp in Ankara and the LibreOffice Development Workshop at the Anadolu University in Eskişehir (Turkey) during the Free Software Wintercamp 2020. These ambitious development courses by Muhammet Kara spawned no less than three of the six successfully submitted LibreOffice projects of GSoC 2020. Find out more about the great outcome of these development camps within our community news blog post.

LibreOffice projects mentored by Collabora Productivity

The student Ahmad Ganzouri has successfully submitted two projects. Supported by the mentors Tomaž Vajngerl, Miklos Vajna, and Michael Meeks, he will work on a project adding blurry shadows to objects in LibreOffice and on a second one that aims to move the current gallery data in favour to easier to handle ZIP files. Yusuf Keten, another participant of the LibreOffice Developers Bootcamp in Ankara, will be working on additions to better integrate extensions. Keten’s project is being mentored by Collabora’s Muhammet Kara.

Also Collabora’s parent company developers are mentoring

Another interesting GSoC project is bringing a CiviCRM integration to LibreOffice and Collabora Office. “Styles Inspector“, also mentored by Tomaž Vajngerl, is another project aimed at LibreOffice. We all look forward to the results of the students work. And for sure we will try to cover some of that here. Another wonderful story is that of Collabora Productivity developer Pranam Lashkari. He was a GSoC student during the last two years while graduating and this year he is already a mentor for two projects within the Boost C++ libraries. Collabora developer Andrej Shadura is mentoring no less than three projects focusing on Android SDK Tools for the Debian operating system. Find out more about these and other noteworthy projects in the Collabora news blog.

Padded Numbering available in Collabora Office 6.2-9

Discover Padded Numbering in Collabora Office 6.2-9

If you work with spreadsheet, you know the numbering formatting with leading zeroes. It has been there since ages. Interesting that now in Writer, you can also have list numbering with leading zeroes: padding numbering.

A great outcome of our hack week

At Collabora, we have that great tradition of calling a hack week once a year, mostly after stressful periods with big releases. During that week the team members can decide for themselves on which projects they want to work. As you can read in his blog, our LibreOffice developer Miklos Vajna used this time to work on the core implementation of Padded Numbering. As you can read in Miklos’ second article on the topic, the final implementation had to overcome some challenges resulting from the different way the OOXML and ODT file formats handle Padded Numbering.

How can I make use of this new feature?

Padded numbering allows you to work with lists in Writer, with a prefix from one to four zeros. The feature is currently premiering in our new enterprise version 6.2.9 of Collabora Office and will be available in the next release of LibreOffice. You can find the feature following the path Format → Bullets and Numbering → Customize and accessing the “Number” list box.

How can I try it out?

We offer up-to-date snapshots of our enterprise-ready office suite for download, which you can use to test the very latest functions. Alternatively, you can request a demo from us to get to experience the stable version of Collabora Office with all its advantages !
