Great Response to the LibreOffice Development Workshop at Free Software Winter Camp 2020

Every Winter the Anadolu University in Eskişehir, Turkey, hosts a large Free Software Winter Camp. This year it took place from Jan 25 – Jan 28, 2020, covering over 50 different classes with more than 40 different topics, and close to 1500 participants tutored by over 100 instructors. One of those classes was the LibreOffice Development Workshop, sponsored by Collabora Productivity.

For the four days of intensive training 20 students from all over the country were accepted. While the workshop itself was free, the participants were expected to cover the costs for travel and accommodation. This year 16 students showed for LibreOffice Development Workshop given by Collabora’s Muhammet Kara – a number which was a significant increase compared to the number from the previous year!

The participants of the LibreOffice Development Workshop at Free Software Winter Camp 2020.

In order to be accepted, the students had to have knowledge in C++, the principals of object-oriented programming, and at least user-level experience on a GNU/Linux system. During the workshop the 16 participants got familiar with the processes and tools of LibreOffice development and bug fixing.

Within the four days workshop the students contributed 64 commits, documented in the LibreOffice wiki. Two memorable examples of contributions were an important improvement by Onur Yilmaz for the Automatic Redaction feature and a Python script to analyse the LibreOffice code-base for styling issues written by Batuhan Taşkaya.

Muhammet Kara reported, that the feedback from the participants was very positive:

“Almost all pointed out that they have improved their development skills, and they would like to continue contributing.”

We would like to take this opportunity to express our appreciation once again to the effort of Muhammet, the Linux Users Association of Turkey and Anadolu University for providing this exceptional training opportunity. We look forward seeing more contributions from that dedicated group of participants.

Collabora supports Free Software Winter Camp 2020 in Eskişehir, Turkey

Twenty-one students have been selected to take part in the LibreOffice Development Workshop at the Anadolu University, Eskişehir, Turkey. It is held from Jan 25 to Jan 28 as a part of the Free Software Winter Camp 2020.

Collabora Sponsored LibreOffice Bootcamp in Ankara
Impression of the previous LibreOffice Bootcamp in Ankara

Collabora Productivity is one of the sponsors. Muhammet Kara, Collabora developer who is giving the LibrOffice training, explains that it’s not suitable for just every interested student.

“Of course enthusiasm is very important. But we also require students to have knowledge/experience with C++, and come with GNU/Linux installed on their laptops. And they will try to build LibreOffice before coming.”

This looks as a perfect match for students that followed for example the LibreOffice Bootcamp in Ankara… but there will be others for sure!
Muhammet tells about the program:

“During the camp, we will go through the usual stuff of getting started with LO development, code- structure, tips&tricks etc. And will work on bugs to gain hands-on experience.”

The accommodations will be provided by the Linux Users Association of Turkey, organizers of the event. Find details on the LibreOffice-wiki too.

Thanks Muhammet, Linux Users Association of Turkey and Anadolu University for making this possible!
Of course we wish the participants good luck, and keep an eye on github for LibreOffice or online 😉

Enthusiast students building LibreOffice – Report from Bootcamp in Ankara

Developing in C++ is not easiest thing you can do in ICT. But if you have some C++ knowledge and skills, it brings you great possibilities. What to think of building LibreOffice and working somewhere in the million lines of code? In Ankara, at the Hacettepe University’s Beytepe Campus, 40 students joining the LibreOffice Developer Bootcamp, just arrived at that point.

Muhammet Kara, Collabora Productivity developer, who gives the courses, tells:

We have finished the 5th session/week of the Bootcamp. So far, we did the following. The first four weeks we did C++ basics, and covered topics such as syntax, operators, data types, arrays, pointers, exceptions.. You name it. On week 2, 3, and 4 the students had to do three home works /assignments. In week 5 we looked at LibreOffice development: how it is organized, who are involved, tooling, habits. And of course: what is good about contributing to LibreOffice. The next week the students should have a complete building environment. So we’ll start the real development: working on easy hacks. More on that in the next report!

Collabora is really glad about the enthusiasm for LibreOffice development and happy to sponsor the Ankara Bootcamp.

The training program attracted much interest from the students side. In the first weeks, which were mainly about the basics of C++, were attended by 120 to 140 students were attending the course. The weekly plans, published on Muhammet Kara’s blog, show the ambitious amount of content they have been introduced to.  The LibreOffice Development Bootcamp was also widely noticed beyond the sphere of the Hacettepe University. The tweets posted on the topic generated many hundreds of interactions and over ten thousand views in the social network.

In week five the specific work on LibreOffice moved more into focus. It was discussed why it makes sense to contribute to it. 40 students took part in this phase of the bootcamp, a great number if you consider that it is not a mandatory course and the demands on the participants were very challenging. The weekly sessions will be given until the end of the semester, January 2020. We will keep you updated here and report about the next weeks of the LibreOffice Developer Camp in Ankara.

 

CODE 4.2.0 Released with fresh User Interface

Clean look, feature rich Side Bar, and much more

Cambridge, United Kingdom, December 16, 2019Collabora Productivity, the driving force behind bringing LibreOffice to the cloud, is excited to announce a new, major release of our product CODE (Collabora Online Development Edition) 4.2.0 This release includes a fresh look, mobile improvements, improved inter-operability, new dialogs and functionality as well as a raft of bug fixes and polish. The release gives you an insight into our soon-to-be released enterprise version Collabora Online 4.2.0. CODE and Collabora Online offer privacy as well as the only truly open-source solution for working with and collaborating on rich documents in the cloud.

What’s new?

This major update of Collabora Online Development Edition (CODE) comes with a rich new user interface and is built onto of the stability and performance of our LTS version of LibreOffice: Collabora Office 6.2. It includes many improvements in functionality and user-friendliness. The most obvious new feature is the powerful sidebar on the right. Many settings for text and all kind of properties of objects in the documents can be easily updated here. The sidebar makes it much easier to change tables, colour settings and charts elements in the browser, with close to the same feature richness that is available in Collabora Office on the desktop. The status bar has been redesigned and our powerful function wizard is now available in Calc online. Copy and paste of rich text and content is added for online, and our responsive user interface adapts nicely to mobile phones and tablets.

Rich chart functions from the side bar

When charts are selected, the sidebar now gives access to a wide range of features. For example, you can easily choose chart types from bars, lines and points, pies and more, or whether the diagram should be displayed in 3D.

Other elements of charts can now also be adjusted from the sidebar. You can now determine how and where titles and legends are displayed. Furthermore, many of the visual elements of the diagram can be adjusted here. The sidebar also allows you to define the surface colour, transparency, line types and grid lines.

Click to see that in action:

Online function wizard: a powerful tool for formulas

Working with formulas is important and especially for the more complex types, having help with the tenth optional parameter is good. The new function wizard does that and it is new available in Calc from now on. The function wizard grants easy access to all elements of also the most complex formulas. It shows the structure and meaning of different parts of a formula, and more.

Conditions apply: Enhanced formatting options in Calc

Conditional formatting is a powerful feature in Calc. It is enables you to quickly visualize data in a spreadsheet by setting various useful rules on your sheet to adapt the cells formatting, colour, or even add icons when certain criteria are met. While a simplified set of conditional formats was previously available via an icon in the toolbar, you can now also make use of the full dialogs, to be found in the Format menu, to define and manage conditions fully.

Better display in Calc: smooth scaling of spreadsheets

The scaling of spreadsheets has been significantly improved in CODE 4.2.0. While in Calc you could previously only choose between two zoom factors of 100% and 200%, now fine adjustment is are possible to suit. Using the convenient (and redesigned) quick selector in the lower right corner, you can now choose your favourite zoom percentage between 33% and 200%.

More presentation functions in the sidebar

The new sidebar adds many useful functions to Impress. For shapes and outlines, the size, position, colours, transparency, wrapping and so on are easy to change.

The possibilities to alter the slide master and lay out, from the sidebar, are also completely new in CODE 4.2. You can now access extensive layout functionality for slides such selecting masters, layouts and even editing your own master pages. Needless to say, that character settings, fonts types, sizes, colours and spacing can also be easily adjusted from the sidebar.

Handier working with images

Working with images in all document types is easier, more convenient and more precise. The sidebar allows to adjust colour options, such as brightness, contrast or transparency or the red, blue and green portion of the image. Another handy feature is the adjustment of the layer settings of the images. Bring them to the foreground or arrange them in the background – all via the sidebar.

Rich copy and paste between docx and xlsx documents and more… in the browser

People that work online, often have many documents open simultaneously, and want to mash them together into bigger, better documents. So you’ll be glad to learn the CODE 4.2.0 introduces copying of rich formatted content along with images, charts, and other complex elements, between your online spreadsheets, documents and presentations.

New online colour picker

For certain elements there is not only the usual colour selector, offering a palette, but also the colour picker to chose any custom colours needed. Use it with text and background in presentations, lines in spreadsheets and presentations, text and background for floating frames in text documents.

Handling links in Writer has just become more pleasant

CODE 4.2.0 brings very nice enhancements when working with hyperlinks. Whenever the mouse cursor is located next to a link or on it, you will be kindly notified by a pop-up dialogue allowing the real target to be inspected and launched conveniently with a single click.

Beautiful new icons and a redesigned theme

The new design of the icons embellishes the upper toolbar. The new theme is tidier has more generous spacing, and is clearer in general. It should increase productivity and reduce friction. Buttons that are selected have a clearer and more distinct highlight too.

The status bar also benefits from our visual redesign. Not only does it look cleaner, it also improves quick access to the functions located there. The language of documents can now also be set via a popup.

Table editing in the side bar and table handles

In Writer it is now possible to manipulate tables extensively from the sidebar and we also added easy to use in-document selection handles, choose either or both. Previously the table dialog had to be used, which was far less convenient. These handles make adjusting row height and column width very user-friendly.

You want to insert rows or columns from here? Of course! Or delete some or all of them? a click! Furthermore, the sidebar also allows you to set the background colour of the cells or to fine-tune their height and width of rows and columns. It becomes even more interesting if you select several cells. Then you can also merge them from the sidebar or distribute them evenly.

 

Table of contents

In text documents, the full table of contents can now be configured with the new dialogs. So even online, you can customize your complex table of contents in a few clicks according to your wishes. For example edit the entries and change style, background or columns.

New: Collabora Office for Android

Great new interface and editing – in beta

We are excited to announce a complete new version of Collabora Office for Android, available now in Google Play, with the following main improvements:

  • A great looking interface, easy to use with just one hand on your phone
  • Editing of complex office documents, not just viewing
  • Now re-uses the same technology as Collabora Online.

In common with other Collabora Productivity products, this new Android release enables people to edit their documents without compromising on privacy. There is no longer a reason to hand over your data to get rich mobile editing.
The new release marks the end of a period of rewriting important parts of the application. We now share much of the code and user experience from Collabora Online’s collaborative editor as well as Collabora Office 6.2 for displaying the documents.

(Please don’t miss the announcement of the release of February 2020!)

 

(minimal version Android 5.0)

A new front end, re-using Collabora Online

The technology under the hood has changed almost completely, with only the LibreOffice core for rendering the documents remained. We removed the previous Fennec tiled renderer, and moved to re-use a our Collabora Online web view. This means our Android app can share the same features as our flagship product Collabora Online. The recently released Collabora Office for iOS uses the same approach. As a result, features and improvements and fixes made foor one solution (online, mobile, desktop) often enhance all the others. The Javascript and CSS base makes contributing to and developing and debugging the app much simpler for people to get involved with.

Getting involved

Once you have got Collabora Office (Google Play), your feedback is much appreciated. Report any problems you find to the bug tracker, and attach any documents related to the issue so developers can investigate. You can also checkout the Online code and build it yourself.

Rich history and community growth

The road to the current version of the Android app was a long one, one with many companions and some detours. The first version that brought LibreOffice to the Android platform was released in 2011 after an intensive process of cross-compiling and a number of bug fixes. This version was rather a proof of concept and by no means suitable for productive work.

Two years later, in 2013, the application had developed into a document viewer rendering entire pages and including basic user interface to handle pages. During the years 2014 to 2015, the rendering was changed to split the pages into „tiles“, the same way as other applications like Mozilla Firefox were doing. We have extracted the Mozilla’s compositing from their code and reused it in our Android app – still only a viewer. Later in this period, editing was added as an experimental feature.
Between 2016 and 2018 further features and functions were implemented thanks to community involvement, however the vision of a full editor was not realized.

In 2019 we decided to do a complete rewrite of everything above the LibreOffice rendering core. Inspiration for this was the development of the new Collabora Office for iOS app, which Collabora is driving forward together with our Swiss partner Adfinis SyGroup. The current, newly developed Android app benefits greatly from the Collabora Online code base and work for the iOS version and includes also features implemented this year during the GSoC, mentored by our engineers.

Thanks to everyone that contributed

This new Office app for Android obviously came by a huge investment from Collabora. As with all open source projects, it has also been made possible by the open source community as a whole, by many organizations and the personal dedication of many individuals that contributed. Specifically, for this Android app we want to mention the initial Android port funded by SUSE. The initial app used the tiled rendering funded by CloudOn, and was driven by Smoose, IceWarp and many customers of Collabora Productivity. The Document Foundation’s donors also funded the initial basic editing functionality.

Without ever doing justice to the entire crowd of supporters, we would like to thank a few people whose performance in this development has been outstanding. At this point, we would like to mention the pioneering work of our fellow two collaborators Tor Lillqvist and Michael Meeks and on the initial version of the App that among others included a first loader developed by Iain Billiet, during his GSoC ‘12 program and other components by Matúš Kukan.

Tomaž Vajngerl contributed to the already mentioned tiled rendering to the app in 2014/2105. Miklos Vajna’s efforts made editing possible at that stage. Christian Lohmaier, Ximeng Zu, and Mert Tumer have made important and substantial contributions by adding more features to the toolbar in the last few years.

Tor Lillquist was also responsible for the development of the Collabora Office for iOS app, which had a significant influence on the version for Android, and was made possible thanks to the great personal commitment of Nicolas Christener of Adfinis SyGroup. Thank you to Kaishu Sahu for his large amount of features programmed during the GSoC this summer, while our team member Jan Holesovsky has been the main developer of the current release.
