Quick tip: creating “hybrid” PDF files in LibreOffice

Screenshot of PDF export dialog

Here’s a LibreOffice feature you may not know about: when exporting a PDF, the “Hybrid PDF” option embeds the original file. Then anyone with a PDF reader can view the file – and LibreOffice users can edit it too.

Insights from the InstallFest 2024 conference in Prague

InstallFest 2024

Our Czech community reports back from a recent event…

For the third time, the LibreOffice project had its own booth at InstallFest 2024, and here we present our experiences from the event.

On the weekend of 16th and 17th March 2024, the InstallFest 2024 conference took place at the Faculty of Electrical Engineering of the Czech Technical University in Prague. The conference was held after a two‑year break and under the direction of a new team led by Jan Langmaier. This year, according to the organisers’ estimates, about 300 visitors attended, making InstallFest a successful follow‑up to previous editions. Unfortunately, higher participation is limited by the space capacity of the chosen venue.

The lack of space also affected the LibreOffice booth, which had to be a bit aside from the main event. On the other hand, anyone heading to one of the main lecture halls could not miss us – our exclusive position made us unmissable. Even so, there were far fewer visitors at our booth than in previous years.

Feedback gained at InstallFest

Conferences of this type appeal mainly to the younger generation, who must not be absent. It is therefore not surprising that young people from primary or secondary school are well represented among the visitors at the LibreOffice stand. This year, however, this was significantly more disproportionate than at other times – it can even be said that young people dominated. We always interviewed them, asking what they use LibreOffice for, how long they have been using it, whether it is used at school, where they go, and whether their classmates know about the suite.

The answers were generally similar. LibreOffice tends to be used by young people for basic tasks such as writing texts, creating presentations for school and so on. Those who create presentations in Impress for school assignments have to convert their presentations to PPTX format. Surprisingly, we’ve had good feedback on compatibility with this format, although it is of course problematic.

InstallFest 2024

Very few visitors know about the cloud or mobile versions of LibreOffice, but there are some. We were surprised that one high school student reported using the cloud‑based, non‑paid version of OnlyOffice; after learning about the circumstances (ie that this software is in Russian hands and thus subject to EU sanctions), he understood why the institute he was working with (apparently a non‑profit of some sort) did not want to purchase the paid version of OnlyOffice. It simply cannot.

Many visitors would welcome some changes in LibreOffice’s user interface. While some prefer the traditional toolbar layout, others prefer a Microsoft Office‑like look and feel – either for personal taste or for ease of transition from Microsoft Office. LibreOffice allows you to use different interfaces, but this option is hidden in the menus. Visitors would appreciate if, when LibreOffice is first launched, a wizard were displayed to guide the newcomer through the various setup and customisation options, including user interface selection.

We received a request from one tutor to allow multiplication of a combinational number by a combinational number in LibreOffice Calc, and also to simplify the notation of simple arithmetic operations such as multiplication and division. Currently this has to be done using verbally defined functions, so he would welcome the ability to use simple symbols typed from the keyboard.

InstallFest 2024

Although it would seem that office software cannot attract the attention of youngsters, one ninth-grader stayed with us for perhaps an hour. Obviously he was the record holder.

Zdenek Crhonek has a huge part in translating the LibreOffice manuals into Czech. These manuals are translated by a whole bunch of volunteers, and we displayed their covers here.
Traditionally, Collabora Online, the cloud version of LibreOffice, which is now very stable and usable and with a really extensive arsenal of features, attracted a lot of interest.

There were many interesting meetings of people who often only know each other from the virtual world; that’s what these conferences are for. A regular visitor to our booth is Ladislav Sieger, PhD., from the Faculty of Electrical Engineering CTU. He always has a problem to solve, an observation, or a comment.

After party

A very interesting opportunity (and meeting) was a visit to the basement of Strahov’s dormitories, where the SH Bastlíři (translated “DYI makers”) created their own facilities, a workshop that is available to (almost) everyone. Here you can come across a server rack on the ceiling of the toilet, a circular machine, a 3D printer and other interesting things. The visit to these premises was followed by a dinner at a nearby restaurant, where the participants from among the organizers (including speakers, technical staff, exhibitors) were taken by a chartered bus (!).

InstallFest 2024


The new organising team has done its task well. If there were problems, we are not aware of them; that is, they were of a completely minor nature. For us, the biggest problem was with the location of the stand; perhaps this played a role in the rather low attendance of interested people. Although we probably had the most space of all in the end and did not have to make any space constraints, we may not have reached as many visitors as we could have.

However, the other perspective should also be taken into account. Although LibreOffice plays a primary role in the world of open‑source software, it is considered a utility that does not attract as much visitor interest. Therefore, we have tentatively agreed with the organisers to change that next time on our side, and they have promised to help us.

Anyway, those who visited our booth hopefully took something away with them (besides stickers and leaflets), especially thanks to Zdeněk, who maintains a lively communication with LibreOffice’s front‑line staff and has information literally first‑hand. He can thus provide far more insider insight than one Czech community member alone on the stand could in previous years.

All of the talks were filmed and the recordings are available on YouTube.

Community Member Monday: Adam Seskunas

Adam Seskunas

Tell us a bit about yourself!

My name is Adam Seskunas and I currently live in San Diego, California. In my free time I enjoy outdoor activities, hiking, backpacking in the Sierra, rock climbing and surfing with my daughter Sofia. I have a degree in Computer Science from the University of Maryland Global Campus, and I’m an open source software enthusiast.

What are you working on in the LibreOffice project right now?

Currently I’m working on my first “Difficulty Interesting” Easy Hack, a nice description of which can be found on this page.

The Easy Hack involves the ASCII filter for LibreOffice Writer and the way it handles the output of tables. True to its name, the Easy Hack has been interesting! It’s been challenging and rewarding at the same time. I’d like to thank Hossein Nourikhah for providing the code pointers and background information, and Michael Weghorn for help in code review.

Why did you choose to join the project, and how was the experience?

I’ve been using LibreOffice ever since I became interested in using Linux, when I was studying for my Computer Science degree, but I never had considered contributing. It’s such a large project, and I had no experience with C++. I just happened to see an advert on VolunteerMatch for bug testing, and answering the ad got me in contact with Ilmari Lauhakangas.

Ilmari would meet with me bi-weekly and he taught me how to verify bugs in Bugzilla and eventually got me into developing. Overall, joining the project been a fantastic experience, from Ilmari’s mentorship to all the people involved – everyone’s been great. I’d highly recommend it to anyone.

Anything else you plan to do in the future?

My plan is to apply and hopefully get accepted to do Google Summer of Code for LibreOffice. I’ve been talking to Hossein about ideas and I’m excited to get my application written and submitted.

What does LibreOffice really need now?

I’d say more contributors. There’s a robust community of contributors, but any project could use more. It’s a great way to meet people and gain some experience. I’d encourage anyone reading this and thinking about contributing to check out the wiki. There’s great information there and you can help in many different ways, not just development.

Many thanks to Adam for all his contributions! Every LibreOffice user is welcome to get involved and find out what they can do in our community �

German state moving 30,000 PCs to LibreOffice

German state moving 30,000 PCs to LibreOffice

Following a successful pilot project, the northern German federal state of Schleswig-Holstein has decided to move from Microsoft Windows and Microsoft Office to Linux and LibreOffice (and other free and open source software) on the 30,000 PCs used in the local government. As reported on the homepage of the Minister-President:

Independent, sustainable, secure: Schleswig-Holstein will be a digital pioneer region and the first German state to introduce a digitally sovereign IT workplace in its state administration. With a cabinet decision to introduce the open-source software LibreOffice as the standard office solution across the board, the government has given the go-ahead for the first step towards complete digital sovereignty in the state, with further steps to follow.

The term digital sovereignty is very important here. If a public administration uses proprietary, closed software that can’t be studied or modified, it is very difficult to know what happens to users’ data:

We have no influence on the operating processes of such [proprietary] solutions and the handling of data, including a possible outflow of data to third countries. As a state, we have a great responsibility towards our citizens and companies to ensure that their data is kept safe with us and we must ensure that we are always in control of the IT solutions we use and that we can act independently as a state.

This follows on from the finding by the European Data Protection Supervisor (EDPS) that the European Commission’s use of Microsoft 365 breaches data protection law.

In addition, there is this question: Why should local governments use taxpayers’ money to buy proprietary, closed software from a single vendor? With LibreOffice and free software, administrations have much more choice where to get the software and support, and can fund local developers to make improvements. In addition, local governments can maintain full control of the software, study its source code, make changes they require and deploy it entirely on their own infrastructure. Learn more about “Public Money, Public Code”.

So we welcome the decision in Schleswig-Holstein to move its IT administration to free and open source software, for all the benefits it brings, both for the local government and the almost three million citizens of the state.

Improve copy&paste in Calc and elsewhere

Calc now supports much better copy&paste when you transfer data between Google Sheets and Calc.

This work is primarily for Collabora Online, but the feature is fully available in desktop Calc as well.


First, Collabora Online was using the deprecated document.execCommand() API to paste text, which is problematic, as the "paste" button on the toolbar can't behave the same way as pressing Ctrl-V on the keyboard.

Second, it turns out Google Sheets came up with some additional HTML attributes to represent spreadsheet data in HTML in a much better way, and Calc HTML import/export had no support for this, while this is all fixable.

Results so far

In short, Collabora Online now uses the Clipboard API to read from the system clipboard -- this has to be supported by the integration, and Calc's HTML filter now support the subset of the Google Sheets markup I figured out so far. This subset is also documented.

Note that the default behavior is that the new Clipboard API is available in Chrome/Safari, but not in Firefox.

For the longer version, here are some screenshots:

We used to show a popup when you clicked on the paste button on the notebookbar

The new paste code in action, handling an image

Import from Google Sheets to Calc: text is auto-converted to a number, bad

Import from Google Sheets to Calc: text is no longer auto-converted to a number, good

HTML import into an active cell edit, only RTF was working there previously

Paste from Google Sheets to Calc: text is no longer auto-converted to a number, good

Paste from Google Sheets to Calc: booleans are now also preserved

Paste from Google Sheets to Calc: number formats are now also preserved

Paste from Google Sheets to Calc: formulas are now also preserved

Paste from Google Sheets to Calc: also handling a single cell

Copy from Calc to Google Sheets: text is now handled, no longer auto-converted to a number

Copy from Calc to Google Sheets: booleans are now handled

Cross-origin iframes also block clipboard access, now fixed

Copy from Calc to Google Sheets: number formats are now also preserved

Copy from Calc to Google Sheets: formulas are now also preserved

Copy from COOL Writer to a text editor: much better result, new one on the right hand side

How is this implemented?

If you would like to know a bit more about how this works, continue reading... :-)

As usual, the high-level problem was addressed by a series of small changes:

The tracking issue on the Online side was cool#8023.

Want to start using this?

You can get a snapshot / demo of Collabora Office 24.04 and try it out yourself right now: try the unstable snapshot. Collabora intends to continue supporting and contributing to LibreOffice, the code is merged so we expect all of this work will be available in TDF's next release too (24.8).

  • Mail, admin, tech planning, COOL community call. Group of partners call, marketing strategy call; lots of calls.
  • Discovered that using an A2 M8 bolt as a die to thread a pencil makes a great fidget toy.
  • Finally got to some hacking; Caolan found the watchdog thread could trigger perf via an unusual syscall (futimestat); but it would just sample the watchdog thread. Fixed that by moving it into a signal handler with signals. Finally can get pretty flamegraph profiles of particularly slow things quite simply with
    perf record -e syscalls:sys_enter_futimesat. Grateful for Brendan Gregg's great profiling site - bought his book for good measure.

Test improvement – More and better tests for LibreOffice

One of the areas that can help LibreOffice, but may not directly be visible to the users even though it has a big impact is the quality assurance, is automated testing.  Here, I discuss some areas and notes around improving tests for LibreOffice. First, I start with regressions and bug fixes without a test.

Missing Unit Tests

This is the description from the GSoC ideas page:

While there are some automated tests for LibreOffice, there are not nearly enough. Adding more and better tests helps developers who work on the code to be more productive by allowing them to find regressions as early as possible.

To elaborate more, I should say there are many regressions and bugs in general that are fixed, but lack testing. It is important to have tests for those bug fixes, to avoid such problems in the future. You can see a list of those fixed issues that lack tests here:

If you want to add some new tests for the bug fixes, first you should read the bug report very carefully to understand what is it about, and try to test the fix yourself. You can either use git revert command to revert the fix, and see the problem in action, or try changing back the fix in the code, if it is not too big.

That is important, because you have to see that the test fails without the fix in place, but succeeds when it is applied. This is an essential step when writing the test.

To know more about unit tests, you may look into these Wiki pages:

Porting Existing Test to C++ or Python

Some tests are written in the past, but now have issues because of the way they are written. In this case, porting them can provide improvement.

Tests can be written in multiple languages. At least, C++, Python, Java and BASIC are currently in use for different tests across the LibreOffice code base. Again in the GSoC ideas page, you can read:

There is some support in LibreOffice for automated tests, both at the level of unit tests, and at the level of system tests that drive a full LibreOffice instance. Currently tests can be written in C++, Java, or Python. Various new automated tests should be developed to improve the test coverage.

Tests written exclusively for Java (e.g. the JUnit framework) should be ported to C++ so that they can execute much more rapidly. Similarly, tests that do remote control of an existing LibreOffice instance, should be re-factored to run inside that instance to make debugging much easier.

Almost all JUnitTests and UITests, and also some smoke tests, run as an outside process. To verify, the trick is to remove the soffice(.exe) binary, or to remove its execute permission (on Linux). In this way, out-of-process tests should fail, as they need to run the soffice binary. After a successful build, you can see if this works. For example, try this:

make -d JunitTest_framework_complex

As an example, we have this issue around complex tests that should be ported to Python:

You may find many examples of the previously ported test in the issue page. Keep in mind that usually old Java tests should be removed in the same patch that provides the CppUnitTest port.

Also, you may find examples of UITests ported to C++ from Python. For example, see this patch:

It ports a previously implemented UITest from Python to C++. The result is a faster test, which is more robust.

Focusing on a Specific Area

If you want to add or port some tests, please focus on a specific area of the code. The LibreOffice code base is huge, and consists of more than 200 modules. It is not easy, and in fact not suggested, to work across different applications and modules. It is much better that you pick a specific application, and even inside that application, like Writer, Calc, Impress, etc., focus on a specific module. In this way, it would be much easier to understand the ideas and the way tests are implemented.

How Hard is it to Write / Port a Test?

One important question is around the complexity of writing or porting tests. The answer is not straightforward, as it depends on the area that the test is written. But one can take a look at what others did in the past. By looking into Gerrit or git log, you can find what other people, including GSoC applicants, were able to achieve during their work.

After writing a few tests, or porting a few tests, it may become easier for you to write more tests. Another thing is that you don’t have to write tests from scratch. There are many tests available in the LibreOffice code base, and you can create your new test based on existing tests and customize it to match the purpose of the issue you are working on.

Different Units of Measurement in Libreoffice

Git Git Git Git Git Git

Why work on this

Working on this involves understanding the controlls, specially the spinedit, finding some way to modify it so that clicking on the units “the last 2 characters of the label in the spinedit entry” shows a dropdown, from which we can select a different unit.


I find working on this as a great opportunity to get deeper insights into widget implementations

Finding a Starting Point

I had no idea about where to start. One approach that appealed to me was if somehow I find the cursor position when the spinedit goes into edit mode, and compare it to the text length in the GtkEntry (internal) of the spinedit, then I can easily say that if the cursor is on the last 2 characters, then show a dropdown here. But that would not work, because “creating a new widget” ==> the logic should be built into the widget itself (I don’t know, it’s just guess-work).

Then I went to #gtk IRC channel, and asked about how to approach this problem.

IRC Conversation
sahil_ hi, I have a task to write a custom spinedit control, which will have a fontsize field (with a number and a unit like mm, pt, etc). It should be such that if I click on the unit with mouse, then it should show me a dropdown to use different units. Mockup Here’s the mockup. How can I approach it?
sahil_ Libreoffice uses glade and custom welding for widgets. And from the research I did on it, I found that a normal gtkentry is aware of the cursor position, which can be used like if the cursor is on the last 2 characters, then show the popup.
sahil_ But a new control has to be created for that (in my understanding).
mclasen The pieces are GtkText and GtkGestureClick. You just have to glue them together in the right way
sahil_ mclasen: and for the dropdown?
mclasen GtkPopover is what is used for that
sahil_ Also the spinedit doesn’t expose the gtkEntry (it’s internal). So do I have to create one from scratch?
sahil_ or does it?
mclasen you can take a look at how GtkEntry, GtkSpinButton, etc are put together nowadays they are all just wrappers around a GtkText widget

This was more than enough to get started.

Starting the Hunt

Looking into it, I found that I was mixing up GtkComboBox, which is used as fontsizebox, and GtkSpinButton, which is what I was supposed to explore and modify. weld::SpinButton, which is libreoffice’s wrapper over GtkSpinButton (if I am not wrong) has functions which give access to the cursor location in the Entry. It would require some playing around to understand the dynamics though.

I am also curious about how a dialog, or any UI element, which is created using glade, which usually has the widgets as Gtk types (GtkLabel, GtkButton etc.) is loaded into different backends. Knowing how the welding works would answer it I think.

User Hostile Dialog Box

Git Git Git Git Git Git Git

What do I want to achieve

It’s important to set some target before jumping into and starting to do the thing. I would like to make an annoying “Donate Now” dialog

  • The dialog would show up whenever the user starts libreoffice, or whenever he switches to different modules like calc or writer etc.

  • The dialog would look something like the mockup shown below. The dialog should have a faint background image which shows all the community members, to give out cheerfull vibes. Other than that it would have a text which would be some interesting fact about libreoffice.

  • It would have an image on the top, and a “donate now” and a “close” button on the bottom It would also have a checkbox saying “I am broke”, which would be unchecked by default. If the user checks it, then the dialog will stop asking for monitory donations, and instead pester the user with “Other Ways To Contribute”, which would include all the getting involved stuff.

  • Other than that It would also have an “I don’t care” checkbox, which will be unchecked by default, and if checked, the dialog won’t show up again, and then one has to reactivate it from about > user-hostile-donation-dialog.


This would makeup for a nice and fun learning experience. It would involve playing around with the UI, listeners, strings, “the user centiments” etc.

It’s not a rigid outline, but rather an idea to atleast get started. Patch on gerrit.

Starting with the UI

I will start with understanding how the about dialog is implemented, how does it display images and custom text etc. One thing that I noticed previously is that the “Tip Of The Day” dialog uses GtkDrawingArea while the about dialog uses GtkImage.

I asked on the #gtk IRC channel, and found that GtkImage is an image loaded from the disk at a specific size, while GtkDrawingArea is a canvas you draw on using cario.

This might have been the reason for why Libreoffice was carshing when I used GtkImage while trying to recreate the “Tip Of The Day” dialog. There I just created a bare constructor, without specifying the image.

Well for the user hostile dialog, GtkImage would work fine as I don’t need to change the image on the go.

Creating a Dialog

I created a dialog box using glade. The challenge that I faced was that I was not able to move the checkboxes in the ButtonBox of the GtkDialog to the left side. All 4 controls were stuck together. Then I looked into how the tip-of-the-day dialog does it, and there I found that whatever control I wanted to left align (in the button box), I had to turn on the packing > secondary control. What that is, I am still to investigate into.I got this Documentation Reference from the #gtk IRC channel.

For some reason, the dialog doesn’t carsh now :). Other issue that I faced was related to text wrapping. So if I set some long text in a weld::Label using the set_label(OUString) function, then it just expands the dialog to fit in one line. GtkImage is just a bitmap image, for which we specify the size (width) while loading it. For label wrapping, I will look into how the tip-of-the-day dialog does it. Making the dialog resizable doesn’t work as well. Under general > formatting of the GtkLabel there is an option to specify wrapping properties, and just below that are boxes for max width. Playing around with those, I was able to get text wrapping to work.

Sometimes these things feel hard, and I tend to avoid them as much as I can. But Now I realize that it is those hard moments which build me to tackel bigger challenges, and I should be looking for such opportunities. Today I find glade easier to use compared to yesterday

I got the dialog as I wanted. Looks nice! When I was working on the dialog, I changed the SID_ABOUT: unocommand to display the user-hostile-dialog instead of the about dialog. This way I was able to test whether it works as expected or not.


Then I went ahead to work on the listeners and the configuration logic. There should be some way for us to remember what options were checked/unchecked when the dialog was closed (configuration), and some way know which module we are entering, so that we can change the text accordingly (listeners).

What Next?

I figured that for each dialog, we have a generic wrapper class called VclAbstractDialog. It provides “one type for all dialogs” solution, which makes sense. I followed the about/tip-of-the-day dialog to write all these functions and classes. And since I want a menu entry as well, I had to create an unocommand as well. I found that each module, and the start center etc have their own menubar.xml file. I added the user-hostile-dialog entry to most of those.

Adding Listeners

Looking into tip-of-the-day dialog, I found that when it is created, it adds a listener on the parent window, and checks if it is dying or not, and if so then it terminates as well. Then in the destructor, it removes the listener.

For adding listeners to show the dialog on such and such events, I had to read through the SfxViewFrame::Notify function, as described in the Blog. It listens for changes like document created/opened and creates the dialog then.

Remembering Dialog Configuration

The last part was to remember whether the user checked some checkbox or not, and remember that throughout the session, and between new sessions. I defined configuration defaults in xml file officecfg/registry/schema/org/openoffice/Office/Common.xcs and used the path to define a struct, through which we access/set the values, similar to how tip-of-the-day dialog does it.

struct UserHostileDialogDontCare : public comphelper::ConfigurationProperty<LastTipOfTheDayShown, sal_Int32> {
    static OUString path() { static constexpr OUString PATH(u"/org.openoffice.Office.Common/Misc/UserHostileDialogDontCare"_ustr); return PATH; }
    UserHostileDialogDontCare(); // not defined
    ~UserHostileDialogDontCare(); // not defined


Now when the dialog is created , these configuration values are checked, and are used to set the state of the controls. When the dialog is destroyed, these choices are not lost. I forgot to set the type to boolean in the xml file, and as a result, the dialog was not showing up, so that’s something to reember as well, while copy pasting ;).

I added links to the checkboxes as well to change the Donate button to Contribute, if the user says “I’m broke!”

Button Opens Donation/Contribution page

Since the user can either donate or contribute, I had to redirect him to the correct page. For that I looked at how .uno:Donation does it. At first I tried to do it how the .uno:Donation does it, but then I thought why don’t I just call the uno commands!

So when the button is clicked, it dispatches uno commands depending on whether “[ ] I’m broke!” is checked or not.

What’s Left?

Since I want it to be User Hostile, there should be some way to show it when start center is opened. Other than that there should be some way to tell which module is opened, and change the label according to that.

Writer tables converted to plain text – difficultyInteresting EasyHack

If you copy contents from LibreOffice Writer to a plain text editor like gedit or Notepad, you will see that it does a straightforward thing: It copies the text and some basic formatting like converting bullets to ‘•’. For the Writer tables, the conversion is very simple right now: every cell is written in a separate line.

For example, if you have a table like this:

A | B
C | D

When you copy the table from LibreOffice Writer and paste it into a plain text editor, it will become something like this, which is not always desirable.


It is requested that like LibreOffice Calc, or Microsoft Word, and many other programs, the copy/paste mechanism should create a text like this:


The columns are separated by <tab>.

This feature request is filed in Bugzilla as tdf#144576:

Code pointers for Handling Writer tables

There are many steps in copy/pasting, including the data/format conversion and clipboard format handling. Here, you have to know that the document is converted to plain text via “text” filter.

The plaintext (ASCII) filter is located here in the LibreOffice core source code:

Therefore, to change the copy/paste output, you have to fix the ASCII filter. That would also provide the benefit that plain text export will be also fixed as requested here.

In this folder, there are a few files:

$ ls sw/source/filter/ascii/
ascatr.cxx parasc.cxx wrtasc.cxx wrtasc.hxx

To change the output, you have to edit this file:

In this file, there is a loop dedicated to create the output.

// Output all areas of the pam into the ASC file
do {
    bool bTstFly = true;

Inside this loop, the code iterates over the nodes inside the document structure, and extracts text from them. To check for yourself, add the one line below to the code, build LibreOffice, and then test. You will see that a * is appended before each node.

SwTextNode* pNd = m_pCurrentPam->GetPoint()->GetNode().GetTextNode();
if( pNd )
+   Strm().WriteUChar('*');

For example, having this table, with 1 blank paragraph up and down:

A | B
C | D

You will get this after copy/paste into a plain text editor:


To fix the bug, you have to differentiate between table cells and other nodes. Then, you should take care of the table columns and print tab between them.

To go further, you can only add star before table cells:

if( pNd )
    SwTableNode *pTableNd = pNd->FindTableNode();
+   if (pTableNd)
+   {
+       Strm().WriteUChar('*');
+    }

You can look into how other filters handled tables. For example, inside sw/source/filter/html/htmltab.cxx you will see how table is managed, first cell is tracked and appropriate functions to handle HTML table are called.

For the merged cells, the EasyHacker should first checks the behavior in other software, then design and implement the appropriate behavior.

Final Words

Make Impress master slides copyable – difficulty interesting EasyHack

When working with LibreOffice Impress, “Slide Master” is the place where you can change the templates used for different types of the slides used in your presentation. Here we discuss a possible improvement for the “Slide Master” by making the copy from master slides possible.

Copying the Master Page in Impress

To see the problem and the room for enhancement, open LibreOffice Impress, then choose “View->Master->Slide Master” from the menus. Then, try to copy the master page on the left in the slide sorter. Unfortunately, it is not possible.

Impress slide master

Impress slide master

Having this feature is helpful, because different page types have many things in common, and being able to copy/paste helps creating templates much faster.

Impress Code Pointers

Looking into sd/source/core/drawdoc3.cxx, you can see a huge function SdDrawDocument::InsertBookmarkAsPage, which is relevant here. It contains ~600 lines of code. This huge function is in itself a problem. Therefore, to implement the enhancement, on should try to first refactor the function, then add a unit test in sd/qa/unit, find and then separate all the ~6 use cases, and fix the style/name merging.

After the cleanup, the main fix should be implemented. The suggested path to implement this comes from Jean-Francois. He suggest to improve the duplicate() method, which is described in the documentation:

As described in the above documentation, its role is to duplicate a page:

Creates a duplicate of a DrawPage or MasterPage, including the Shapes on that page and inserts it into the same model.

However, the implementation does not work for master slides, as the macros in the attachment file implies. The solution should add the needed implementation for master slides.

The implementation is inside sd/source/ui/unoidl/unomodel.cxx inside duplicate function:

// XDrawPageDuplicator
uno::Reference< drawing::XDrawPage > SAL_CALL SdXImpressDocument::duplicate( const uno::Reference< drawing::XDrawPage >& xPage )



Final Words

The above issue is filed as tdf#45617. If you like to work on it, just follow the Bugzilla link to see more information.

To implement this feature, first you have to build LibreOffice from the sources. If you have not done that yet, please refer to this guide first:

Fixing multi-view programming challenges in Calc and elsewhere

This post describes some challenges around having multiple views of one opened document in LibreOffice core, when those views belong to LOK views, representing different users, with their own language, locale and other view settings.

This work is primarily for Collabora Online, but is useful for all clients of the LOK API.


LOK views are meant to represent separate users, so we need to make sure that when a user sets their preferences and trigger an action, then the response to that action goes to the correct view, with the correct view settings.

This is different from the desktop LibreOffice use-case, where multiple windows are still meant to share the same user name, language, undo stack and so on.

Results so far

In this post, I would like to present 4 small improvements that recently happened to the LOK API to provide this wanted separation of views.

The first was an issue where two users were editing the same document, one busily typing and the other clicked on a link in Calc. What could happen sometimes is the link popup appeared for the user who typed, not for the user who clicked on the link:

Link popup is actually on the left, should be on the right, now fixed

This specific problem can be fixed by making sure that link click callbacks are invoked synchronously (while the clicking view is still active) and not later, when the current view may or may not be the correct one.

It turns out the same problem (async command dispatch) affects not only hyperlinks, but many other cases as well, where we want to stay async, for example, when one dialog would invoke another dialog, like the Calc conditional format -> add dialog:

Calc conditional format add dialog appearing on the left, should be on the right, now fixed

There you don't want to change async commands into sync commands, because that may mean spinning the main loop inside a dialog, resulting in nested main loops. This can be fixed by making sure that async commands to be dispatched (sfx2 hints in general) are processed in a way that the current view at dispatch & processing is the same, which is now the case.

The third problem was around wrong language & locale in the status bar:

Unexpected English strings in localized statubar UI, now fixed

This is not simply a problem of missing translation, the trouble was that the status bar update is also async and by the time the update happened, the locale of the view on the left was used, for a string that appears on the right.

The way to fix this is to perform the update of toolbars/statusbar/etc (in general: SfxBindings) in a way that the language at job schedule time and at UI string creation time is the same.

The last problem was quite similar, still about bad language on the UI, but this time on the sidebar:

Unexpected English strings in localized sidebar UI, now fixed

This is similar to the statusbar case, but the sidebar has its own executor for its async jobs, so that needed a fix similar to what the statusbar already had, now done.

How is this implemented?

If you would like to know a bit more about how this works, continue reading... :-)

As usual, the high-level problem was addressed by a series of small changes:

Want to start using this?

You can get the latest Collabora Online Development Edition 23.05 and try it out yourself right now: try the development edition. Collabora intends to continue supporting and contributing to LibreOffice, the code is merged so we expect all of this work will be available in TDF's next release too (24.8).

gbuild for Java tests – LibreOffice build system part 3

In this blog post, I discuss gbuild for Java tests. The goal is to write a Makefile to compile and run a JUnit test for LibreOffice. You can also refer to part 1 and part 2 for a brif overiew on gbuild, the LibreOffice build system.

Macro Examples from gbuild for Java Tests

In the first post on gbuild, I have mentioned some macro examples including gb_Output_announce which was used to print nice messages like the ones including “[CXX]”. Now let’s explain some more macros related to Java tests.

Consider that you want to compile and run a JUnitTest. To do that, you need to write the test in a Java file, and create a Makefile to run that.

This is an example for running a test defined in Java file sw/qa/complex/indeterminateState/

$(eval $(call gb_JunitTest_JunitTest,sw_complex))

$(eval $(call gb_JunitTest_add_sourcefiles,sw_complex,\
sw/qa/complex/indeterminateState/CheckIndeterminateState \

$(eval $(call gb_JunitTest_use_unoapi_jars,sw_complex))

$(eval $(call gb_JunitTest_add_classes,sw_complex,\
complex.indeterminateState.CheckIndeterminateState \

The make file for running this Java test consists of calling multiple macros. It starts with gb_JunitTest_JunitTest macro, which defines the test by its name, sw_complex. This macro is defined in solenv/gbuild/ If you grep for define in the same file, you will see this result:

$ grep -w define solenv/gbuild/
define gb_JunitTest_JunitTest
define gb_JunitTest_set_defs
define gb_JunitTest_add_classes
define gb_JunitTest_add_class
define gb_JunitTest_add_sourcefile
define gb_JunitTest_add_sourcefiles
define gb_JunitTest_use_jar
define gb_JunitTest_use_jars
define gb_JunitTest_use_jar_classset
define gb_JunitTest_add_classpath
define gb_JunitTest_use_system_jar
define gb_JunitTest_use_system_jars
define gb_JunitTest_use_external
define gb_JunitTest_use_externals
define gb_JunitTest_use_customtarget
define gb_JunitTest_use_customtargets
define gb_JunitTest_use_unoapi_jars
define gb_JunitTest_use_unoapi_test_class
define gb_JunitTest_set_unoapi_test_defaults
define gb_JunitTest_JunitTest

To stick to the macros used in the above example, I describe these macros:

gb_JunitTest_add_sourcefiles: This macro adds a Java source file to the test. It defines the code that adds the sw/qa/complex/indeterminateState/ to the test. But please note that you should drop the .java extension:

$(eval $(call gb_JunitTest_add_sourcefiles,sw_complex,\
sw/qa/complex/indeterminateState/CheckIndeterminateState \

The other macro gb_JunitTest_use_unoapi_jars, adds the UNO API JAR files to be used with the test.

And in the end, you need to add the test class name using gb_JunitTest_add_classes macro. The class name is visible in the end.

The result can be quite complex, but it works. 🙂

java.exe -Xmx64M -classpath "$W/JavaClassSet/JunitTest/sw_complex;C:/cygwin64/home/user/lode/opt/share/java/junit.jar;$I/program;$W/Jar/OOoRunner.jar;$I/program/classes/libreoffice.jar;$W/Jar/test.jar" -Dorg.openoffice.test.arg.soffice="path:$I/program/soffice" -Dorg.openoffice.test.arg.env=PATH="$PATH" -Dorg.openoffice.test.arg.user=file:///$W/JunitTest/sw_complex/user org.junit.runner.JUnitCore complex.indeterminateState.CheckIndeterminateState

The above is the actual command that runs the test. Please note that if you forget the gb_JunitTest_add_classes macro to define the class name, the test may compile, but it will not run.

As an example, you can see the below patch. This patch fixes the problem of the JUnit test not running:

Final Words

Many macros are available in gbuild, making easier to create Makefiles to compile and run tests, build libraries and executable applications and many other relevant tasks. The best way to find and understand these macros is to look at the Makefiles written by others to the same task. Look for .mk files, and if you want to see the implementation of the macros, look into solenv/gbuild/.

I will write more about gbuild macros in the next series of blog posts on gbuild.

gbuild tips and tricks – LibreOffice build system part 2

In the first blog post on LibreOffice build system, gbuild which uses GNU Make, I discussed some of the features of it. Here I discuss more about some gbuild tips and tricks that you may need.

Building a Single Module

In order to build a single module, you need to use its name. For example, to build only “odk”, which contains office development kit, you only have to type:

make odk

On the other hand, there are many other build targets associated with odk. By typing make odk, and then pressing tab, you will see this list, which shows possible targets:

odk odk.buildall odk.perfcheck odk.uicheck odk.all odk.check odk.screenshot odk.unitcheck odk.allbuild odk.checkall odk.showdeliverables odk.allcheck odk.clean odk.slowcheck odk.coverage odk.subsequentcheck

Each of the above is related to a specific task, in which many of them are common on different modules. Let’s discuss some of them:

make odk -> Builds odk module.

make odk.clean -> Cleans the odk module, removing the generated files.

make odk.check -> Runs test in odk module

make odk.uicheck -> It runs UI tests inside odk module

make odk.perfchek -> Runs performance/callgrind tests inside odk module

make odk.screenshot -> Creates screenshots inside odk module

To get a complete list and detailed description, run make help.

Handling Incomplete Builds

Sometimes because of OS crash or power outage, you may face problems when a build is stopped forcefully. In that case, you may see several zero byte object (*.o) files that exist, and prevent a successful build. In that case, you can find and remove them using this command:

$ rm `find -name *.o -size 0`

After that, you can retry your build without the above problem.

Customizing Build Configuration

The process of creating Makefile starts from configuring LibreOffice for build. This is done by invoking ./ The configuration parameters are read from autogen.input. The build configuration is done via, which is an input for GNU autoconf.

There are various steps before the Makefiles are generated. For example, in order to make sure that a library is there when configuring the build, a very small C/C++ file is created, compiled and tested to ensure that the library is ready, and available to use with C/C++ code.

It is also possible to check for some specific version of library, and available functions. As an example, see this patch, which checks for specific version of ZXing library:

In the above example, multiple situations are handled:

1) When there is no ZXing library

2) When system ZXing library is used

And also, it is checked that specific version of ZXing is available:

1) When ZXing::ToSVG is not usable

2) When ZXing::ToSVG is usable

Then, the HAVE_ZXING_TOSVG symbolic constant is used in config_host/, which can be used in C++ code.

Knowing More About gbuild

If you are interested in knowing more about gbuild, you can start from my first post on gbuild in this blog. I plan to write more about gbuild, and describe some of the frequently used macros.

Also, you can take a look at the article devoted to gbuild in the TDF Wiki:

Comments in Sidebar

Using comments is a key feature in text processing. A typical workflow might be to review a document where notes are made by different colleagues. LibreOffice Writer currently shows these comments in the document margin, which is limited to the page height, ending up in the need to scroll long text (even while editing [1]) and eventually in paging-like interactions if the number of comments exceed the total size.…

Multi-page floating tables in Writer: tables wrapping tables

This post is part of a series to describe how Writer now gets a feature to handle tables that are both floating and span over multiple pages.

This work is primarily for Collabora Online, but is useful on the desktop as well. See the 10th post for the previous part.


Previous posts described the hardest part of multi-page floating tables: making sure that text can wrap around them and they can split across pages. In this part, we'll look at a case where that content is not just text, but the wrapping content itself is also a table.

Results so far

Regarding testing of the floating table feature in general, the core.git repository has 92 files now which are focusing on correct handling of floating tables (filenames matching floattable-|floating-table-). This doesn't count cases where the document model is built using C++ code in the memory and then we assert the result of some operation.

Here are some screenshots from the improvements this month:

Improved click handling near the first page of a floating table

The first screenshot shows a situation where the mouse cursor is near the right edge of the first page of a floating table. What used to happen is we found this position close to the invisible anchor of the floating table on that page, then corrected this position to be at the real anchor on the last page. In short, the user clicked on one page and we jumped to the last page. This is now fixed, we notice that part of the floating table is close to the click position and we correct the cursor to be at the closest position inside the table's content.

A floating table, wrapped by an inline table: old, new and reference rendering

The next screenshot shows a floating table where the content wrapping around the table happens to be an inline table. You can see how such wrapping didn't happen in the past, and the new rendering is close to the reference now.

How is this implemented?

If you would like to know a bit more about how this works, continue reading... :-)

As usual, the high-level problem was addressed by a series of small changes:

Want to start using this?

You can get a snapshot / demo of Collabora Office 23.05 and try it out yourself right now: try the unstable snapshot. Collabora intends to continue supporting and contributing to LibreOffice, the code is merged so we expect all of this work will be available in TDF's next release too (24.8).

Multi-page floating tables in Writer: UI improvements

This post is part of a series to describe how Writer now gets a feature to handle tables that are both floating and span over multiple pages.

This work is primarily for Collabora Online, but is useful on the desktop as well. See the 9th post for the previous part.


Previous posts described the hardest part of multi-page floating tables: reading them from documents, so we layout and render them. In this part, you can read about UI improvements when it comes to creating, updating and deleting them in Writer.

Results so far

Regarding testing of the floating table feature in general, the core.git repository has 89 files now which are focusing on correct handling of floating tables (filenames matching floattable-|floating-table-). This doesn't count cases where the document model is built using C++ code in the memory and then we assert the result of some operation.

Here are some screenshots from the improvements this month:

Improved insertion of floating tables

The first screenshot shows that the underlying LibreOffice Insert Frame dialog is now async (compatible with collaborative editing) and is now exposed in the Collabora Online notebookbar.

There were other improvements as well, so in case you select a whole table and insert a new frame, the result is close to what the DOCX import creates to floating tables. This includes a default frame width that matches the table width, and also disabling frame borders, since the table can already have one.

Unfloating a floating table

The next screenshot shows an inserted floating table, where the context menu allows updating the properties of an already inserted floating table, and also allows to delete ("unfloat") it.

Several of these changes are shared improvements between LibreOffice and Collabora Online, so everyone benefits. For example, inserting a frame when a whole table was selected also cleared the undo stack, which is now fixed. Or unfloating table was only possible if some part of the table was clipped, but now this is always possible to do.

How is this implemented?

I like it here. Can I stay?

(And do you have a vacancy for a back-scrubber?)

Thank you, Red Hat, for generously letting me work for so long on stuff that is near and dear to my heart. At the intersection of theory and practice, of compiler technology and the LibreOffice code base. But, to keep doing what I love, I need to move on.

So, thank you, allotropia, for having me. I’m excited.

And, above all, thank you, LibreOffice, family of friends. Lets make sure to keep this a happy family, one that Tolstoy would have nothing to write home about. With quarrels and arguments, for sure; feud even. But happy at heart. I wish to keep meeting you all for years to come, virtually, and for a feast at FOSDEM or LOCon. And booze.

To paraphrase Hamburger Tafel (donations needed, btw), “Wir haben LibreOffice noch lange nicht satt.”

Have fun, stay safe, peace,

Is developing word processing software hard?

Hello LibreOffice Planet!

This is my first blog post on the topic of LibreOffice. Let me quickly explain my link to LibreOffice. I work for a data protection authority in the EU and help navigate the digital transformation of our office with about 100 staff members. While many of our partner organisations adopt Microsoft 365, our office decided to pilot Nextcloud with Collabora Office Online.

In the future, I want to blog (in my personal capacity) about my thoughts related to the use of alternative word processing software in the public sector in general and in our specific case.

As there are no dedicated resources for training, preparation of templates etc., during the pilot of LibreOffice, the experience so far covers a large spectrum of user satisfaction. Generally, our staff has been spent years of their life using Microsoft Office and has the expectation that any other software works the same way. If it does not, they send an email to me (best case) or switch back to Microsoft Office.

During the week, I discussed again some smaller LibreOffice bugs. Then, I showed this weekend some FOSS Blender animated short videos to family members. It seems that Blender is more successful in its domain than LibreOffice. Is that possible? Or are animated short videos just more capturing due to their special effects? 😅

You can watch the 1min Blender animated short movie “CREST� on Youtube or the making-off. The latter you find here below.

I find it very inspiring to see what talented artists can do with Blender. For my part, I have once installed Blender and deinstalled it. Back then it was not easy to use for people not familiar with video animation software. Blender competes with proprietary software such as Maya or Cinema 4D. The latter is about 60 USD per month in the annual subscription plan. Not exactly cheap.

Then, I read in the fediverse about people working with LibreOffice:

I just tried to use #LibreOffice #Draw to draw some arrows and boxes onto JPEG images for emphasizing stuff.

The UX is really bad for somebody not working with Draw all the time.

Whatever I do, instead of drawing onto the image, the image gets selected instead.

Could not find any layer-sidebar.

Could not scale text without starting the “Character …� menu, modifying font size blindly + confirming > just to see its effect and then start all over.

Dear #FOSS, we really should do better.

In my past, I have worked on online voting systems. They are not very good yet despite years of efforts. xkcd dedicated a comic to voting software

Elections seem simple—aren’t they just counting? But they have a unique, challenging combination of security and privacy requirements. The stakes are high; the context is adversarial; the electorate needs to be convinced that the results are correct; and the secrecy of the ballot must be ensured. And they have practical constraints: time is of the essence, and voting systems need to be affordable and maintainable, and usable by voters, election officials, and pollworkers.

— Author Matthew Bernhard et al. in their paper Public Evidence from Secret Ballots from 2017

What is the unique challenge of developing word processing software? Happy to hear back from you in the blog comments or on the companion fediverse post!

LOUCA23 (LibreOffice Conference Asia x UbuCon Asia 2023)

Long time no see, readers!  Very sorry for my laziness.

I attended LibreOffice Conference Asia x UbuCon Asia 2023 (LOUCA23) in Surakarta, Indonesia, on October 7~8.

This was the second time LibreOffice Conference Asia has been held in Tokyo in 2019, as it could not occur due to the COVID-19 pandemic.  UbuCon Asia was first held online in 2021, and the first in-person event was held in Seoul, Korea in 2022, and this still was the second in-person event.

I was burnt out by the pandemic and had stopped most of my OSS activities, but I still had many friends in the OSS world, so I went to Indonesia to meet with them.  

Therefore, I had initially intended to be a general participant.  Still, a friend of the speaker was suddenly unable to attend due to illness, so I gave a presentation in his place.  Here is my slide:

As mentioned, I am halfway out of OSS activities, but I know what my friends are doing, so it was not so difficult to talk about this subject.

Although I cannot say that the presentation itself was a great success (due to my English language skills), I was pleased because the audience was very responsive and easy to talk to, and many people approached me after the presentation was over.

Other than my presentation, I was naturally interested in the two keynote speeches by The Document Foundation and was surprised and grateful when Franklin Weng mentioned my name as an "Asian activist to be featured at the LibreOffice Latin America Conference. "

I listened to Muhammad Syazwan Md Khusaini's "Hands-On on Translating in Ubuntu" with great interest; however, I was a bit surprised to hear from a friend that many Indonesians use English for desktop environments and applications like LibreOffice.  I recognized that this was quite different from Japan.

The event itself was just as enthusiastic. Unlike OSS events in Japan (laugh), the participants were young, and there were many women. I was also surprised to see junior high school students among the speakers.

Both lunch and dinner were complimentary, and the one-day Surakaruta city tour the day after the event was delightful.  I appreciated the hospitality of the local staff.

This was my first time in Indonesia, and although short, I enjoyed many things, including the train trip. In Yogyakarta, I visited a museum and learned a lot about the history of Indonesia. However, I was overcharged by the tuk-tuk in Yogya.

I know it was a lot of work for the organizers, but as I have many friends in LibreOffice and am also an Ubuntu user, I was very grateful that the two events were co-hosted. Thanks to all the sponsors, global/local organizers, and everyone who talked to me there.  See you soon!

Final Report - Google Summer of Code 2023 - Search Field in Options

About project

LibreOffice is a complex application with a large and growing number of options. It is not easy to find the right needle in the haystack. Like most other complex applications, it will be valuable and useful enhancement to add a search field to the “Tools > Options” dialog that iterates over the various tabs and filters where the search text is found. The Search Field in Options project aims to provide this search functionality in “Tools > Options” page.


  •   Add search field to Options dialog - UI
  •   Implement search function
  •   Include Options TreeView’s parent and child node names into searching
  •   Add GetAllStrings() method to fetch strings from 69 dialogs step by step
  •   Include following element strings into searching:
    •   labels
    •   check buttons
    •   radio buttons
    •   toggle buttons
    •   link buttons
    •   buttons
  •   Include accessibility elements into searching:
    •   accessible-names
    •   accessible-descriptions
    •   tooltip-texts
  •   Include option pages from extensions into searching
  •   Initialize all dialogs at background if it’s possible (salhelper::Thread - asynchronously)
  •   Initialize all dialogs to get strings properly (not in background - synchronously)
    •   initialize ~half of them after opening the options
    •   and initialize remaining ones after doing a search
  •   Update Options TreeView properly after the searching done
  •   Expand the first node and select first child-node after search by default
  •   Remove Hyphen (_) and Tilde (~) symbols from fetched strings to make the search function work correctly

My Work during GSoC

During 13 weeks GSoC program, I added a search field in Options dialog and included the node names and their .ui strings into searching. Since sub-dialogs under the Options are not initialized at startup of Options dialog, it was not possible to access their .ui strings. To overcome this issue we had two options:

  • Option A: Extract .ui strings at build-time and fetch them at run-time
    This option requires working on file operations, LibreOffice’s build system, makefiles, localization etc. I worked on this option for ~5 weeks but this approach caused a lot of issues that took the project out of its scope. For example, how to deal with localization issue while extracting strings at build-time? This was another big problem…
  • Option B: Initialize all dialogs in some way and get their strings
    This option is more understandable and simple. Instructions are clear. No need to worry about localization. No need to work on file operations, extracting and fetching data, working with makefiles etc…

When I felt that Option A is just wasting my time (~5 weeks); I switched to Option B where I can -at least- make some progress. The main issue in Option B was initializing all dialogs which takes about 4-8 secs. I tried to initialize them at background but there was some errors on Win10 that I don’t reproduce the issue on my linux machine. Then I tried to see the errors on Win10 with a virtual machine, but it was too slow to test. Therefore I uninstalled Manjaro/Linux (which I’ve been using it more than 1.5 years) from my computer and had to install Win10 (which I last used 6 years ago) on my machine to see the problems in there. There was some visual inconsistencies while initializing sub-dialogs using salhelper::Thread at background.

After working long hours for weeks meanwhile the time was running out, I decided to initialize almost half of them at Options dialog startup and the remaining ones at the time of searching. In that way, time of initializing process is divided by ~2 which can be acceptable time in some degree in terms of user experience.

There is a single patch on Gerrit for this project: The patch has more than 30 patchsets and includes “+2255 -47” changes.

The most challenging part was implementing GetAllStrings() function for every ~69 dialogs step by step. Current implementation may not be the best solution for user experience, but at least searching through the numerous options is now possible.


Whats left to do or can be done?

Following tasks are left and can be implemented after GSoC:

  •   Include accessibility elements into searching:
    •   accessible-names
    •   accessible-descriptions
    •   tooltip-texts
  •   Include option pages from extensions into searching
  •   Initialize all dialogs at background if it’s possible (salhelper::Thread - asynchronously)

Additional hacks

  • Show modified options with some special indicator (as in KDE settings). (better to discuss this idea in a separate ticket)
  • Implement highlighting feature

Tasks I’ll be working on after GSoC

  • improvement on the initialization of the dialogs, maybe it can be possible to initialize them at background without encountering any visual inconsistencies - especially on Windows.
  • Implementing the remaining tasks:
    • Include accessibility elements into searching
    • Include option pages from extensions into searching
  • If everything works fine I’d like to work on the highlighting feature
  • Also it would be prettier if Options dialog have a modified options indicator (as in KDE settings)


I’m very happy that we all reached the end of GSoC. During that time, I know that I had a responsibility for doing everything that I can. Therefore I worked hard and tried to complete as much tasks as I can.

I learned a lot of things during the GSoC. Although GSoC is finished, I will definitely continue to contribute to LibreOffice. I am really happy to be a part of the LibreOffice community and Google Summer of Code. I’m really thankful to LibreOffice and Google for providing us this such a great opportunity which helped me gain this amazing experience!

I always tried to be active on IRC #libreoffice-dev channel, and I want to thank for everybody who helped me about my questions.

And most importantly, greatly thankful to Andreas Heinisch and Heiko Tietze who were my mentors throughout the GSoC period. They always guided me everything about my questions. Thank you endlessly for your time and effort. I appreciate that you always motivating and encouraging me in all that I attempt and do. I can never truly express how grateful I am. Your guidance, reviews, help and shared experiences have been invaluable. Thank you very much for everything.

I’d like to express my gratitude to everyone in the LibreOffice community for their help and kindness. They always tried to answer my questions on IRC. I fell very lucky to work with this amazing community. I have learned a lot from you and I will never forget this wonderful experience.

Final Report

The past four months working on LibreOffice for Google Summer of Code 2023 have been an amazing learning experience. With the help of mentors Thorsten, Heiko, and Hossein, I implemented features to improve the user experience around digital signing and encryption like remembering recipients, better recipient selection UI, fast searching/filtering of keys, and documentation. My 12 patches were merged and it was incredible contributing to open source with the friendly LibreOffice community. I look forward to more FOSS contributions in the future!

Small Caps in Impress

Writer supports Small Caps, but Impress and drawing shapes in general never fully supported Small Caps. The option was available, and the character dialog provided a preview, but Small Caps was rendered the same as All Caps, as seen here.

 This has lingered for years and it's not easy as a user to try and manually workaround with varying font sizes because underline/overline/strike-through decorations won't link up, as seen in this example:

 but finally for Collabora Hack Week I was able to carve out some time to fix this. So in today's LibreOffice trunk we finally have this implemented as:

In addition a buggy case seen in the preview of double overlines for mixed upper/lower case was also fixed, from:


Also noticed during all of this was the wrong width scaling used for the red wave line underneath incorrect spelling in impress when the text is superscript or subscript so the line didn't stretch over the whole text, as seen here: 

Now corrected as:

and finally added was a missing implementation in the RTF export of shape text to allow the small caps format to be copy and pasted into other applications from impress.
