  • Thanks to Rizal Muttaqin for syncing our Colibre icon sets, making them match the newest Colibre color scheme, and also updating Impress sidebar icons, thus making the general look of Collabora Online more appealing and coherent in colors.
  • Thanks to Alan Verdugo[0], corleone77[1], Batuhan Görkem Benzer[2] and Mücahid Aydin[3] for improving our Python scripts by fixing Pylint errors, thus increasing readability, and making them more developer-friendly.
  • Thanks to Dilaver Demirel[0], Pelin Kuran[1] and Buğra Kurt[2] for fixing code styling issues on our Javascript files towards upgrading our eslint version to 4.0.0. This will bring a bunch of fixes and improvements for one of our depended libraries.
  • Thanks to Andreas Kainz for catching the discrepancy between the widths of Style and Font dropdown lists, and fixing it quickly. He also has multiple other pull requests and issues created, currently in-review, aiming for different fixes and improvements such as syncing COOL icon path with LibreOffice icon path, which will make it way easier to sync icon work between COOL and LibO in the future. Another pull request he is working on together with Pedro Pinto Silva is on revamping the menubar content and arrangement to be in alignment with LibreOffice.
  • Thanks to Yusuf Keten for porting unique pointers in wsd to Util::make_unique(), thus preventing possible memory leaks.

Thank you all, and welcome aboard! 🙂

Join the fun!

You can also join the fun, and be part of our next list of new contributors! 🙂

Just go to our GitHub repo, fork it, build it, grab one of our newcomer-friendly easy hacks, and send your first pull request. And if you get stuck at any point, just drop by one of our communication channels.

Oh, last but not least: We are also participating in the Hacktoberfest. So don’t forget to check our hacktoberfest issues. 😉


New, easy way to build and test

To start developing, you need to first build CODE, and we have build instructions for you on our community website. However, they were a bit generic to be compatible with different platforms & Linux distros. Now we have started adding straightforward, easy-to-follow instructions specific to different distros, and the first one is Ubuntu 20.04 LTS. If you are on a different distro, and would like to contribute a new set of instructions for it, please feel free to get in touch!

Thanks to our new daily archives of LibreOffice core builds, now you can just download the necessary pieces and directly start building CODE itself, instead of also build LibreOffice core from scratch.

And as always, please don’t hesitate to report any issues, or better, send pull requests to fix them. 😉

Now easy to get developing on any platform!

On top of our daily LibreOffice core archives, we have also added integration support for Gitpod, a cloud based development environment. Now you can start hacking Collabora Online in under ~5 minutes! You might want to keep an eye on our Twitter account in case a quick video tutorial comes up in the following days. 😉

Steps to quick start:

  • Sign-up on with your GitHub account
  • Install the proper extension for your browser
  • Go to COOL repo
  • Click on the green Gitpod button

    Gitpod button near the top of the GitHub repo page
  • Wait for a few minutes, and you will have a full development environment with COOL already cloned & built, ready-to-start/develop

  • Don’t forget to also fork the main repo
  • And set the remote address in .git/config to point to your fork’s address with this command:
    git remote set-url origin

Happy hacking! 🙂

Collabora Online (COOL)

  • Starting to develop Collabora Online is now easier and quicker than ever, thanks to initial support for Gitpod -cloud-based development environment- being merged by Muhammet Kara.
  • Thanks to Miklos Vajna for introducing Util::make_unique() method which helps to prevent potential memory leaks in case of an exception thrown between the allocation of memory for a raw pointer and the construction of an std::unique_ptr, and also for hardening COOL by fixing a potential issue.
  • Thanks to Szymon Kłos for fixing interference of sidebar tooltips between views, causing a mix-up of languages, and for fixing a crash which occurs while using a mobile phone when leaving chart edit mode with chart type modified.

Last but not least, we can’t thank enough to our translators who constantly help COOL and its friends talk many languages on this earth. Collabora Online speaks many languages, thanks to all of our translators in our translation project, and all of those who previously contributed and keeps contributing to our mother project, LibreOffice.

We’re continuing to work to find good ways to credit translators’ hard work in the product. Please see a list of those involved, and please get in touch if you’re not listed. Many thanks to all those who have worked on translating Online, you rock!

Listening to our translators

In the previous weeks, our translators reported that the platform we were using was once open source, but no longer, and there are open source alternatives that can be used in alignment with our open source mission/spirit. So we listened, and switched to weblate!

If you would like to help COOL speak your language, you can just go to our translation project on weblate, and start contributing! 😉

Collabora loves LibreOffice!

We’re still contributing to LibreOffice and encourage you too to do so because LibreOffice rocks. 😉
