GSoC 21 Projects mentored by Collabora for LibreOffice

Collabora mentors students on LibreOffice projects during this year’s Google Summer of Code

Summer is synonymous with the opportunity to participate in beautiful projects. Let’s look at the students who work in improving LibreOffice during the Google Summer of Code. This year, four of the approved GSoC projects for the LibreOffice community are mentored by Collabora developers. Find out about the improvements they are currently implementing!

Tests for the VCL graphic backends

The Visual Class Library (VCL) tests identifies if a graphic backend works correctly. This is especially important if the backend depends on the client hardware or drivers (like e.g. on Skia/Vulkan). This task’s main objective is adding more test cases to the pre-existing tests, and implementing a usable UI for users to test the graphic’s feasibility themselves. This project can be considered as of medium difficulty and requires C++ knowledge. It has been taken over by Akshit Kushwaha who is being mentored by Collaborans Tomaž Vajngerl and Luboš Luňák.

Creating a powerful Text Style deck

Text Style deck mock-up by the LibreOffice design team

The current styles deck sidebar is going to see a redesign. The paragraph and character styles will be merged into a single Text Style deck, as illustrated in the mock-up to the left. Furthermore, Anshu Khare, who has picked-up this project, does also want to rework the filter workflow. Anshu Khare is being mentored by Collaborans Tomaž Vajngerl and Mike Kaganski and Heiko Tietze from the LibreOffice design team.

Making SVM format independent of the VCL Metafile

The SVM file is a 1-to-1 pullout of the content of the VCL Metafile. We mentioned the VCL already before. It is a complex code area and since the SVM should not change, stay consistent, modernizing and updating VCL is very hard. Now after this task, there will be a test for the SVM format. And there will also be new classes, making it easier to update/improve VCL. This project can be considered of medium difficulty. It is being taken over by Panos Korovesis who is being mentored by Tomaž Vajngerl and Miklos Vajna.

100 paper cuts

100 Paper Cuts is a versatile and multifaceted project in which Bayram Çiçek will be implementing enhancement requests and solving some issues on the UX side of LibreOffice. This requires knowledge in C++ and the ability to read other peoples code. Due to its nature, the difficulty of this project can vary. Bayram Çiçek is being mentored by Collaboran Muhammet Kara and Heiko Tietze from the LibreOffice design team.

More Projects – Boost.Gil 2D convolution and correlation

Apart from those for the LibreOffice project, Collaboran developers participate in other Google Summer of Code projects. For the Boost C++ Libraries organization, a 2D convolution and correlation algorithm aligned with existing 1D convolution and correlation is to be implemented. Prathamesh Tagore will improve the existing prototype and make it ready for release. He is being mentored by Collaboran Pranam Lashkari, who was himself a successful GSoC scholarship holder a few years ago.

We wish all participants an equally successful and insightful summer and would like to thank all mentors for devoting the time necessary for the success of these projects. At Collabora, we believe that the sharing of knowledge is an essential part of open source and also a driver of progress and innovation.

Background information

Collabora, a leading contributor to the LibreOffice codebase and community, is the driving force behind putting LibreOffice in the cloud. Initial development started back in 2011 and four years later, in 2015, CODE (Collabora Online Development Edition) was created, allowing people to check out LibreOffice in the cloud for the very first time. Shortly after this, the first production-ready Collabora Online was released.

We encourage people to contribute. While Collabora has done more than 95% of code commits so far, we are glad that since the move of collaboraonline to github more people are getting involved. Maybe you can join too?

Collabora developers mentor successful GSoC Projects

Autumn is just around the corner. For many participants in the GSoC 2020, a busy and instructive summer full of hacking on open source projects came to an end a few weeks ago. Commits have been contributed and final reports have been written. This year experienced Collabora Productivity developers were again mentors for various projects of the Google Summer of Code for the LibreOffice project. Here are some examples of projects our team helped to succeed!

Analysing Writer documents with the “Style Inspector”

The “Style Inspector” is a great new tool. You can access it through a new icon (an eye combined with a pencil) in the Sidebar (also via “Sidebar Settings”). The Style Inspector displays in full detail (and hierarchical) all styles and also direct formatting applied to a cursor position in a Writer document. So you can analyse, identify problems and clean them up. Sometimes formatting in documents is messy and people mix styles with direct formatting. The Style Inspector allows you to see that.
The feature is available for testing in pre-released development versions of LibreOffice. Shivan Kumar Singh picked up the proposal from the LibreOffice Design Team. He was mentored by Collaborans TomažVajngerl and MikeKaganski with Heiko Tietze from the LibreOffice Design Team. Take a look into Singh’s final report! It is an inspiring a guide on how to approach a big project like LibreOffice.

Improving the way to find and add extensions

There are many useful extensions to LibreOffice and users should be able to find them easily! Like in app stores like Gnome Software or the Play Store. That is basic idea behind “Tight Integrations” and the proposal from the LibreOffice design team. Yusuf Keten made this his GSOC project a success and added the possibility to search and sort the through extensions without having to leave LibreOffice. You start this new way to search with a clear yellow star with a download arrow, that is in the templates dialog, at the icons in the view options, or from the galleries pane in the side bar.
If you are curios about this handy extensions feature you can already test and find it in the latest LibreOffice pre-releases. Yusuf was mentored ba Collabora’s Muhammet Kara and Heiko Tietze from the LibreOffice design team. Find all the details of Yusuf’s work in his final report.

I learned a lot of things during the GSoC. Although GSoC is finished, I will continue to contribute to LibreOffice. I am very happy to be part of the LibreOffice community.(Yusuf Keten)

Access the Tight Integrations manager through the icon in Gallery
Browse, search and sort through Templates, Galleries & Icons in the new extension dialog.

Changing the contour – shadows are becoming blurry

New blurry shadow option

Did you know, that in LibreOffice the shadows are just a copy of the object? There are already a lot of settings to change their appearance, like its colour, its angle, the transparency and distance behind the object. Mentored by Collaboran’s TomažVajngerl and Miklos Vajna, Ahmad Ganzouri added another option. The “Blurry Shadows” make use of the already implemented BitmapFilterStackBlur and make the shape of the shadow look very realistic. Find the details around the development in Ahmad’s final report. We have seen the Blurry Shadow option in the master branch and expect it to be available to all users in Version 7.1 of LibreOffice. The option can be easily accessed via the “Area” dialog in “Objects & Shapes” or directly via the corresponding Sidebar module.

The blur setting can be defined Area dialog.

Searching for a mentor? Join us GitHub!

Google Summers of Code are an excellent opportunity to learn working in many open source projects. But where to find mentors during the rest of the year? We recently moved the code of Collabora Online to GitHub. You will find a growing community there, with easy hacks to get started. Community Mentor Muhammet Kara and the rest of our team of open source developers are there and willing to share their vast experience.

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.
