Content controls in Writer: PDF export and combo box type

Writer now supports exporting content controls to PDF and a 7th content control type: it is possible to differentiate between drop-downs and combo boxes.

This work is primarily for Collabora Online, see the previous post for background.

Motivation

PDF export of Writer content controls into PDF

Writer users can create fillable forms using content controls, but the PDF export only contained the plain text representation of them. PDF can also have fillable widgets for form filling, so it's logical to map content controls to PDF widgets.

A perfect mapping is not possible, since PDF widgets are always a single rectangle and Writer content controls is a list of rectangles (text portions), but this doesn't cause a problem in most cases. The size of the PDF rectangle is determined based on the placeholder's size from Writer.

Benefits includes not having to insert a control shape, manually positioned to look like it's in line with the surrounding text. An other benefit is that this way the widget's style (font name, size, etc) can be specified using Writer styles, not with shape properties. It's also interesting that Word itself doesn't seem to support content controls in its PDF export at the time of writing.

Results so far

PDF export now automatically turns Writer content controls into fillable widgets for the rich text, plain text, checkbox, drop-down, combo box and date types.

Combo box itself is a new type: now combo box content can be either free-form or one of its list items, while drop-down can only be one of its list items.

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 22.05 and try it out yourself right now: try 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 (7.5).

Meet Skyler – Collabora Software Engineering Intern

 

Collabora recruits interns to work over the summer alongside our team, and to build experience to help them assess whether they want to pursue a career in Software Engineering, but how does that work out? Lets hear from Skyler:

Tell me about yourself!

My name is Skyler and I’m currently studying Maths, Further Maths, Computer Science and Business Studies at college. I spent the summer holidays doing an internship at Collabora Productivity. I’m into software development and video games, especially Minecraft and Celeste. I have a huge Steam library!

When did you first become interested in technology/coding?

When I was 11, my parents got me Raspberry Pi and I became fascinated with learning how to programme. Then in Secondary school I had an awesome Computer Science teacher who let us use old laptops to create a server where we built a small internal website. Since then I’ve been doing software development as a hobby.

What’s your favourite project you’ve worked on?

Oh, there’s quite a few to choose from! I’ve made several Discord bots which are automated game bots, including one to play Cards Against Humanity which was installed on over 2000 servers. I also made a version of Ultimate Tic Tac Toe – you can access it at https://uttt.crawling.us. I particularly enjoy creating smaller things that feed into one another to create something larger.

What have you been doing over the summer?

I’ve mostly been working on JSDialog, such as ‘repair document’, ‘number format’ or ‘split table’. I think the most common (and arguably most important) one I’ve worked on is ‘insert captions’ which is ~90% done: there’s 3 dialogs that work together to make our captioning work and I’ve converted 2 of them fully and figured out but not fully fixed an issue for the third.

Why did you want to spend your Summer interning at Collabora?

I went to a talk by Michael at my school where he told us about the benefits we’d get from doing an internship. He mentioned developing scalable techniques for big projects which I thought would be interesting and useful to learn.

I would have spent all Summer doing software programming anyway so I thought instead of letting the summer slip away, I would spend it learning. Plus it looks good on a university application!

What did you learn from your time at Collabora?

The main thing I learnt was the importance of taking notes efficiently so you can see what you were thinking and see if there were any assumptions you made that were wrong. I also learned how to implement scalable techniques (as Michael was talking about) which has really helped me.

What do you want to be working on in the future?

I’ve thought of various things I’d like to work on but I really enjoy back end development, much more than front end. I enjoy DevOps, scripts and testing – it’s satisfying to test and deploy.

I’m applying for university to do a Computer Science course focused on theory and software development and hopefully I’ll be able to get involved with some more projects at Collabora around my studies.

Would you recommend an internship at Collabora to others interested in a career in technology?

Yes absolutely, I’ve encouraged a few of my friends at school to apply!

 

It has been great to have Skyler work with us, and to see the impact on the codebase for all our users. Making our user-interface more visually consistent helps users to have a more easy to use and seamless experience. The underlying code improvements will also help to reduce complexity, making life easy for the next contributors to Collabora Online.

Why not get involved? We love to work alongside the next generation to help them discover what a career in Software Engineering might look like. If you’ve ever considered it for yourself, get in touch today!

LibreOffice Community on Mac app store

On September 19, The Document Foundation (TDF) announced the release of LibreOffice on Apple’s Mac App Store, to support end users who want to get all of their desktop software from Apple’s sales channel. TDF will continue to provide LibreOffice for macOS free from the LibreOffice website, which is the recommended source for all users.

LibreOffice packaged for the Mac App Store is based on the same source code, but does not include Java – because external dependencies are not allowed on the store – and therefore limits the functionalities of LibreOffice Base.

The full TDF blog post is here.

Lox365 extension: XLOOKUP (and more) for LibreOffice Calc

More news from the LibreOffice subreddit! User goose_pirate posted about an extension:

Hi everyone, I made this little extension for LibreOffice Calc which adds a few functions, currently FILTER, SORT, and XLOOKUP. I hope others will find this as useful as I do.

XLOOKUP is a function for finding things in a table by range or row. We asked goose_pirate for a bit of background on the extension:

I’ve been using both Excel and LibreOffice for many years and found the new(er) Excel functions like XLOOKUP to be really nice compared to the old VLOOKUP or INDEX MATCH. I wanted to use it in LibreOffice too, so I wrote this extension.

How I made it: I researched information about LibreOffice extensions, dissected a few such extensions made by others, and finally started my own. It wasn’t too bad, I was surprised no one has made something similar yet.

Great work, goose! 😊

Crowdfund audio recording and playback in LibreOffice presentations!

LibreOffice’s presentation tool, Impress, includes a bunch of features for home and office use. But one thing that’s missing is recording and playback for audio comments in presentations.

Please confirm that you want to play a YouTube video. By accepting, you will be accessing content from YouTube, a service provided by an external third party.

YouTube privacy policy

If you accept this notice, your choice will be saved and the page will refresh.

This feature is important in eLearning: in contrast to video recordings, audio recordings are stored per slide, and can be adjusted to match the individual pace of the presentation. This is particularly suitable in school, academic as well as corporate environments to make learning content and product presentations more interactive.

So, how can we get this feature in LibreOffice? Well, the CH Open association, which has been promoting open systems and standards in the Swiss ICT landscape for over 40 years, is organising a crowdfunding campaign to implement the feature. The project is estimated to cost €62,000 in total – with various milestones along the way.

Video tutorials for LibreOffice Writer, Calc and Impress

On the LibreOffice subreddit, we became aware of some useful tutorial videos created by Steven Davids. These cover various components of the suite, and show how to achieve common tasks.

We asked Steven about how he chooses the topics for his videos, and how he makes them:

My video tutorials come to me – I do not go and look for them. If I have a problem, I search for a solution on the web. I always assume I am not unique, and that many other people had or have the same problem. If I do not find a solution or one that is readily available, I struggle my way out to a solution. Then I share that solution via video! Why video? Because it seems to me people are lazy to read and video illustrations are just easier to understand.

The videos are very low budget and homemade. There are no costs for the software since I use free public open-source programs for the screen recorder and video editor. There are many such programs, but OBS Studio and Shotcut serves me very well. I often use LibreOffice Presentation to assist in presenting the material. The hardware is also low cost. I already have a laptop and mobile phone so there are not extra costs there. A mid-range microphone from Samson is indispensable and basically the only additional cost.

16384 columns in Collabora Online

 After the work to support 16384 columns in LibreOffice Calc I have also made sure that the feature works also in Collabora Online, thanks to the funding of NGI.

This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 871498.

 

 

 

 

Since the Calc core is the same, the underlying functionality works just like in LibreOffice. But the online functionality presented some additional challenges that needed handling, as having more cells in a spreadsheet may mean more data sent over the network, slowing things down. There definitely used to be problems with large spreadsheets, as the tiled rendering used by Online in fact was already limited to 500000 rows compared to 1048576 rows of the desktop version (in fact, git history shows that this started at only 1000 rows initially and then was continually raised over the time as things improved). So together with raising column count to 16384 I have raised this to the normal 1048576 rows as well.

While working on this, one of the problems I needed to handle was a rather unusual one - some automated tests were failing because of timing out. Only with debug builds, because they of course do more checks compared to optimized release builds. And the problem turned out to be how some tests checked resulting spreadsheets after some operations. Since testing Calc running in a browser is more complicated than testing the desktop version, what the tests did was to select a large number of cells (e.g. one entire row), paste that to the clipboard and then the clipboard data was present in browsers HTML data, so the testing framework could test it and verify it is as expected. And this failed with unoptimized debug builds because even though the spreadsheet was almost empty, the unoptimized code checked every cell involved and together it added up enough to exceed the test timeout. Ironically enough, a significant portion was spent in code that was trying to optimize the size of the clipboard data. So I needed to improve the tests and optimize handling of unoptimized code, as strange as it may sound.

Now with hopefully all performance problems solved, Collabora Online 22.05 should support these spreadsheet sizes just as fine as the desktop version.

Chart Data Tables

Chart data table is a feature of charts, that presents in the chart area a data table with the values that are visualised by the chart. The data table is positioned automatically at the bottom of the chart, and can for certain chart types replace the X-axis labels. Until now this feature has been missing in LibreOffice, but thanks to the funding of NGI, it is now implemented.


This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 871498




Figure 1: Charts with a data table

Chart data table usage and description

Figure 2: Insert data table dialog


The chart data table can be added to the chart from the menu (Insert -> Data Table...), where it is possible to select to show the data table and set the data table specific properties (see Figure 2). The data table specific properties are:

  • Show Horizontal Border
  • Show Vertical Border
  • Show Outline
  • Show Keys
The properties "Show Horizontal Border" and "Show Vertical Border" control if the inner horizontal or vertical borders of the data table are shown or not. The "Show Outline" controls if the outline - borders around the data table are shown or not. "Show Key" controls if the legend keys for the data series are shown in the data table in addition to the data series (row) names.

Figure 3: Data Table Dialog


In addition to those data table specific properties it is also possible to change the line, fill and font properties of the data table (see Figure 3). For example the line properties define how the borders (lines) will be shown, so it is possible to change the line style (continuous line, dashes, dots), the colour of the line, transparency, line thickness. The fill properties defines the colour of the cell background and the font properties what font and size the is used for the text in the data tables.

Implementation

The data table implementation is located in the chart2 component, like all the other chart related code. A data table is represented in the model by a new DataTable (chart2/source/inc/DataTable.hxx) class (extending the XDataTable interface) and lives on the "Diagram" object. If there is no DataTable object, it means the data table is turned off. The DataTable holds the data table specific properties as well as line, fill and font properties.

The automatic positioning of the data table is done similar like the x-axis labels, as the data table is also meant to replace the x-axis labels, unless it is not able to do so, because of the chart type (for example the "bar chart", which has the main x and y axis swapped). 

Rendering is done on the DataTableView class (chart2/source/view/inc/DataTableView.hxx), which creates a table shape and positions that into the chart. The row headers (data series names) and column headers (x-axis names) and values (from the data series) are filled into the table cell by cell, where also the cell properties are mapped from the model (DataTable class), so the data table looks correctly.

Document format support

Data table is supported by OOXML (c:dTable element). There was already present reading and writing of the basic data table properties ("horizontal border", "vertical border" and "outline" but not "keys") to preserve the document formatting even when LibreOffice couldn't render the data table itself. The properties however were not present at a convenient place (directly on the Dialog object in the model) so this had to be refactored to use a DataTable class instead. Now the OOXML support can not only preserve the complete properties (including line, fill, font) and of course also render the data table properly. 

Support for the ODF format had to be added into the LibreOffice extended namespace. This was done with a "data-table" element that was added to the "chart:chart" element. The "data-table" element only has a link to a certain style instance (linked with "style-name" attribute to a style:style element with the same "name" attribute). The data table specific properties are attributes of the "chart-properties" element ("loext:show-horizontal-border", "loext:show-vertical-border", loext:show-outline", "loext:show-keys" attributes), that can be added to a style. The style can also have "graphic-properties" and "text-properties", which are mapped to line, fill and text properties of the data table on import (and vice-versa on the export).

The support for the data tables is currently available in LibreOffice master and will be present as a feature of LibreOffice 7.5 when released.

Crash fixes for LibreOffice, part 1: segfaults

One of the bugs that we see in computer programs including LibreOffice is the crash. You’re working with the application, and the program is suddenly closed! Here we discuss the usual causes for these crashes, and how to fix some of them.

Crash Report

Crash Report

There can be many reasons for a crash in C/C++, including segmentation faults (segfaults), assertion failures, aborts, and exceptions that lead to abort. Here we discuss the segmentation faults.

Usual Causes for the Segmentation Fault Crashes

There can be many reasons for a segfault in C/C++, and most of them are are related to the incorrect use of memory. For example:

1. Accessing memory that the program does now own
2. Using memory outside the allocated parts
3. Using uninitialized variables

If you use a variable without properly initializing it, that may lead to a segfault. For example:

int main() {
    int *p;
    *p = 1;
    return 0;
}

Trying to de-reference a null pointer also leads to crash.

int main() {
    int *p = nullptr;
    *p = 1;'
    return 0;
}

$ g++ main.cpp -o main; ./main
Segmentation fault (core dumped)

In C/C++, most compilers do not check the array bounds automatically. When working with arrays, you have to take care that you are accessing inside the array bounds, and not beyond them. Look at this example:

int main() {
    int a[10];
    a[1000000] = 1;
    return 0;
}

When working with pointers, it is important to make sure that the pointer is not null before working with it. For example, look at this file:

sc/source/ui/view/tabview.cxx

Inside it, look at this method:

bool lcl_HasRowOutline( const ScViewData& rViewData )
{
    const ScOutlineTable* pTable = rViewData.GetDocument().GetOutlineTable(rViewData.GetTabNo());
    if (pTable)
    {
    const ScOutlineArray& rArray = pTable->GetRowArray();
    if ( rArray.GetDepth() > 0 )
        return true;
    }
    return false;
}

Here, before working with pTable, with the condition “if (pTable)“, we make sure that the pTable pointer is not null.

That is also the case when working with arguments. Look at this function inside the same file:

IMPL_LINK_NOARG(ScTabView, TimerHdl, Timer *, void)
{
    if (pTimerWindow)
        pTimerWindow->MouseMove( aTimerMEvt );
}

The condition makes sure that pTimerWindow is not null.

How to Fix the segfaults?

To describe how to fix some of the segfaults, I discuss to fixes that are merged recently by Caolan and me.

First, please take a look at this recently fixed crash by Caolan:

The crash was happening when you created a page break, and then tried to edit it. The backtrace showed that the problem is happening in this file:

sw/source/uibase/docvw/PageBreakWin.cxx

inside this method:

IMPL_LINK_NOARG(SwPageBreakWin, FadeHandler, Timer *, void)

just in this line, when invoking IsVisible().

if (IsVisible( ) && m_nFadeRate > 0 && m_nFadeRate < 100)
    m_aFadeTimer.Start();

In a debug session for LibreOffice, one can see that the window object is actually destroyed, but the code wants to check if the window is visible or not. In this way, it leads to a segfault. Looking carefully, it becomes visible that the problem comes from some lines below that. We see that m_pLine->DestroyWin() is invoked, but the control sequence is working in a way that IsVisible() is called right after that. To fix this, Caolan simply added a return after destroying the window, and it fixed the problem.

    if ( m_bIsAppearing && m_nFadeRate > 0 )
        m_nFadeRate -= 25;
    else if ( !m_bIsAppearing && m_nFadeRate < 100 ) m_nFadeRate += 25; if ( m_nFadeRate != 100 && !IsVisible() ) Show(); else if ( m_nFadeRate == 100 && IsVisible( ) ) {
        Hide();
        m_pLine->DestroyWin();
    }
    else
    {
        m_pLine->UpdatePosition();
        PaintButton();
    }

    if (IsVisible( ) && m_nFadeRate > 0 && m_nFadeRate < 100)
        m_aFadeTimer.Start();</pre

    if (IsVisible( ) && m_nFadeRate > 0 && m_nFadeRate < 100)
        m_aFadeTimer.Start();

Different Fixes for the Crashes

Not all the crashes can be fixed this way. Sometimes, you have to work on the logic of the application in a higher abstraction level, to be able to fix the crash. For example, see one of the crashes that I have fixed recently.

You could select many footnotes by pressing up/down keys and holding shift, then delete all the footnotes at once. Then, hovering on a reference of such a footnote, lead to crash.

To fix the crash, I bibisected the problem to find the responsible commit. In that specific change, the commit author changed the behavior of the arrow keys to be able to to go to the beginning of the first line just by pressing up in the first line. Also, the same behavior for the last line was also part of the goal.

To fix the problem, I reduced the behavior change to anywhere other than the footnotes, and set the previous behavior for the footnotes. With this change, the crash no longer happened.

More Information

There are many other types of crashes, and many other tricks for fixing those crashes. If you look for the crash fixes, you will find many of them, and take a look into them.

I will continue this tutorial, and talk about other sources of crashes including assert failures, aborts, and exceptions that lead to abort.

Cropped video for media shapes in Impress

Impress now supports cropped videos in slide edit mode and during slideshow for documents imported from PowerPoint.

First, thanks to our partner SUSE for working with Collabora to make this possible.

Motivation

PowerPoint-style cropped video in Impress

PowerPoint handles videos by taking a preview bitmap from the video, and then it allows users to apply various effects on that bitmap, like cropping. The complex aspect of this is that such filters are also respected while playing the video as well.

Impress didn't store such properties on the media shape, which lead to distorted aspect ratio when playing some cropped videos from PPTX files. This lead to this preview in Impress before the work:

Video with lost cropping in Impress

Results so far

The first problem was that the Impress preview was picked from the 3rd second of the video (presumably to avoid a black preview in many videos that start with a short black fade-in), while PowerPoint can store an explicit preview from the video (seems to be the first frame), so no matter what effects you apply, the previews were just different as the source bitmap was different. This could be fixed by looking for an explicitly provided bitmap for the video first, and only then asking the various avmedia/ backends to produce a preview.

Once the preview's initial bitmap was OK, it was necessary to take cropping into account. This was first done for the preview bitmap, and then also for the gstreamer backend (the relevant one for Linux, as a start) of avmedia/, which is responsible for the actual video playback. The gstreamer bits were done by first creating a videocrop element and then connecting that to the existing playbin.

With these sorted out, we get rendering which matches the reference:

Cropped video in PowerPoint

The last step was to load/save the explicit preview and the crop from/to ODF as well, not only PPTX. We use a markup like this to store the information:

<style:style style:name="gr1">
  <style:graphic-properties fo:clip="rect(0cm, 1.356cm, 0cm, 1.356cm)"/>
</style:style>

And now that the gr1 automatic style is defined, we can refer to it from a media shape:

<draw:frame draw:name="test" draw:style-name="gr1">
  <draw:plugin xlink:href="..." xlink:type="simple" xlink:show="embed" xlink:actuate="onLoad" draw:mime-type="application/vnd.sun.star.media">
    ...
  </draw:plugin>
  <draw:image xlink:href="Pictures/MediaPreview1.png"/>
</draw:frame>

The nice property of this markup is that automatic styles are already used for other shapes and image previews are also used for e.g. table shapes, so this is just using existing markup in a new context, but the ODF spec already allows this markup.

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:

User interface to create such a crop, support for other video effects (e.g. black-and-white) and other backends (Windows, macOS) could be done, but is future work currently.

Want to start using this?

You can get a snapshot / demo of Collabora Office and try it out yourself right now: try 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 (7.5).

LibreOffice Dev Blog

ODF standard and the code – EasyHack

Open Document Format (ODF) is a standard (ISO/IEC 26300) and native file format that LibreOffice uses. OASIS developed this file format based on the file format of StarOffice, the ancestor of LibreOffice.

To understand the ODF standard, working with the LibreOffice code and fixing a small bug is enlightening. Here we discuss a related EasyHack.

ODF File Extensions

If you are a LibreOffice user, you may already know these extensions:

.odt for text processing documents (LibreOffice Writer)

.odp for presentations (LibreOffice Impress)

.ods for spreadsheets (LibreOffice Calc)

.odg for drawings (LibreOffice Draw)

.odf for formulas (LibreOffice Math)

Essentially, these are zip files containing XML and binary files. Additionally, Open Document Format can also be text-only format with the extensions of .fodt, .fods and .fodg instead of .odt, .ods, and odg respectively.

Open Document Specification

OASIS website provides the documents that describe the Open Document Format extensively . You can find the specifications for ODF 1.3, which is the latest version of the standard here:

OpenDocument V1.3 OASIS Standard published

Beside LibreOffice, several other applications support ODF standard, including Microsoft Office, ONLYOFFICE, Calligra Suite, Google Docs, and many others! But here, we focus on LibreOffice.

Basically, LibreOffice handles the Open Document format by opening the zip file using the zip parser and the deflate algorithm, and then parses the XML files inside it using libxml2 library.

On the other hand, the meaning of the XML tags and attributes are available via the specification from OASIS. In essence, the specification describes the text, pictures, shapes and other elements of the text processing, presentations, spreadsheets and formulas. Additionally, ODF standard discusses accessibility, collaboration and many more topics.

An EasyHack Related to ODF

To best way to understand the ODF standard, is working with the LibreOffice code. Please take a look at this small bug, which has the label of EasyHack (tdf#150302):

In this EasyHack, there is a sample document which is using a specific feature in the drawings. Looking at the <draw:enhanced-geometry> tag, one can see that there is an attribute draw:text-path-same-letter-heights that is used to control the way that text is rendered in shapes. It is described in ODF standard as:

19.224 draw:text-path-same-letter-heights

The draw:text-path-same-letter-heights attribute specifies if all letters in a custom shape have the same height.

The defined values for the attribute are:

  • false: letters in a custom shape need not have the same height.
  • true: letters in a custom shape have the same height.

The default value for this attribute is false.

The issue is that handling this parameter in the code is not correct. Specifically, the effect of this bug is that if you open the sample file and click on the SameLetterHeights button in the Fontwork toolbar, nothing happens. On the other hand, the correct behavior should be that the shape changes, and “shows the characters vertical stretched to fit the place between the paths”.

Shapes inside the example ODF file

Shapes inside the example ODF file

After all, to fix this issue one should refer to the code pointer that Regina Henschel has provided:

If you open the file core/svx/source/toolbars/fontworkbar.cxx, you will see that the else part is missing, and that is the cause of the problem. Specifically, you should fix that part of the code, and then submit your changes to Gerrit. To begin, please refer to this page for more information on how to submit code to LibreOffice Gerrit:

Writing a Test for the Fix

The fix is rather straightforward, but this is not the end of the task! Furthermore, you have to make sure that the problem does not happen again. In order to achieve this goal, writing a unit test is necessary. The test code should open the example file, and then use the toolbar option. This is possible by invoking .uno:FontworkSameLetterHeights command.

Fontwork toolbar, SameLetterHeightsFontwork toolbar: SameLetterHeights is the second icon is the second icon

Fontwork toolbar: SameLetterHeights is the second icon

There are some examples in sd/qa/unit/uiimpress.cxx that invoke UNO commands, and you may use as the starting point.

Final Notes

EasyHacks are good starting points for the newcomers. This specific improvement is filed as tdf#150302.

If you want to contribute to LibreOffice code by working on this improvement, but you need to know how to get started with LibreOffice development, I suggest you to see our video tutorial:

Content controls in Writer: the plain text type

Writer now supports a 6th content control type: it is possible to insert a plain text content control.

This work is primarily for Collabora Online, done as a HackWeek project, but the feature is fully available in desktop Writer as well.

Motivation

Word-style plain text content control, user interface

Writer users can put a content control around a piece of rich text, see Content controls in Writer: dropdown, picture and date types for the first five types.

The next step in this journey is plain text: even if one of the big advantages of content controls over input fields is that they allow rich formatting, sometimes you want to restrict this. For example, if one has to fill in their name, then it makes no sense to mark the family name as bold while leaving the given name as non-bold. This would just lead to inconsistent look.

Results so far

There is now a new Form → Content Controls → Insert Plain Text Content Control menu item to create a plain text content control. If you try to make a selection that is a subset of the text inside the content control and you try to format it, the whole text in the content control is formatted to maintain the invariant that plain text has no formatting itself, just the formatting of the whole content control.

As usual, you can delete this content control later. You can also load/save it to ODT/DOCX and it's preserved.

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 22.05 and try it out yourself right now: try 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 (7.5).

  • Poked at some hackery, added some debugging bits to the forkit to chase a problem. Submitted a LibOCon paper really looking forward to meeting up with people in person. And continued working on our very awesome (but no longer co-located) COOL days which will be in Berlin immediately afterwards with Eloy.

Making unsorted lookups in Calc fast

 The VLOOKUP spreadsheet function by default requires the searched data to be sorted, and in that case it performs a fast binary search. If the data is not sorted (for example if it would be impractical to have the data that way), it is possible to explicitly tell VLOOKUP that the data is not sorted, in which case Calc did a linear one-by-one lookup. And there are other functions such as COUNTIF or SUMIF that essentially do a lookup too, and those cannot even be told that the data is sorted and so they processed the data linearly. With large spreadsheets this can actually take a noticeably long time. Bugreports such as tdf#139444, tdf#144777 or tdf#146546 say operations in such spreadsheets take minutes to complete, or even "freeze".

I wanted to do something about those for quite a while, as with the right idea making those much faster should be actually fairly simple. And the simple idea I had was to let Calc to sort the data first and then use fast binary search. These documents usually do lookups in the same fixed range of cells, so the linear search in the same unsorted data was rather a waste when done repeatedly. Surely Calc should be able to sort the data just once, cache it and then use that cached sort order repeatedly. In fact VLOOKUP already had a cache for results of lookup in the same area, used when doing lookup in the same row but different columns.

I finally found the time to do something about this when SUSE filled a bug to Collabora about their internal documents freezing on load and then crashing after 10 minutes. The LO thread pool class has a 10 minutes timeout as a safety measure after which it aborts, and the large number of lookups in the documents actually managed to exceed that timeout. So I can't actually say how slow it was before :), but I can quote Gerald Pfeifer from SUSE reporting the final numbers:

BeforeAfter
76m:56s CPU time (crash)9s CPU time (6s clock time)
126m:23s CPU time (crash)25s CPU time (15s clock time)
160m+ CPU time (crash)38s CPU time (23s clock time)
8m:56s CPU time (8m:56s clock time)14s CPU time (5s clock time)

This work is available in LibreOffice 7.4, and the TDF bugreports show similar improvements. In fact tdf#144777, titled "countifs() in Calc is slower than Excel's countifs()", now has a final comment saying that MS Office 2021 can do a specific document in 26s and LO 7.4 can do it in 2s. Good enough, I guess :).

Vote on the LibreOffice branding icons

LibreOffice iconsThe LibreOffice application icons are undoubtedly awesome. But over the years they have become a bit dated and do not fit well into the zeitgeisty icon design. Plus, the set has no good main icon, which is in particular an issue on macOS where this icon is shown on the launcher bar.…

Document themes in Impress: shape fill

Impress now has the next step of document theme support: it is possible to refer to the theme colors from shape fill colors (including effects).

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

Motivation

PowerPoint-style themed shape fill, user interface

PowerPoint users can attach a set of colors (and fonts, etc.) to master pages, and then refer to these in many areas, like shape text or shape fill. It was already possible to define theme colors and refer to them from shape text (see Start of document themes in Impress: shape text for details).

The next step in this journey is shape fill: if your shape is filled with some color, it can be a theme color, as visible on the above screenshot. One interesting aspect of this is that the default shape fill color can now depend on the master page, and it may not be the same for all slides (this is what would happen with styles, when not using theming).

Results so far

Here is a demo that shows how it works:

If one opens the svx/qa/unit/data/theme.pptx test file from core.git, it looks like this:

PowerPoint-style themed shape fill, after opening

The middle row has 3 rounded rectangles: the first is filled with the 'Accent 1' color, the second is the same, but 60% lighter and finally the last one is the same, but 25% darker.

Here is how you can change what the 'Accent 1' color is:

  • Click 'Master View' on the sidebar to go to the master of the current slide.
  • Right click -> 'Slide Properties' opens the 'Slide Properties' dialog.
  • The 'Theme' page has an 'Accent 1' row, with a blue color.
  • Change that to an orange color: click on the 'Accent 1' drop-down, then select 'Theme colors', finally the 6th choice is orange in the first row -- this comes from the document's theme.
  • Click 'OK' to close the dialog, followed by 'Close Master View' on the sidebar.

Here is how your shapes now look like:

PowerPoint-style themed shape fill, after changing the theme

What you can see here is that the color effect (darker, lighter, default) of the rounded rectangles' fill color was preserved, but all the blue colors are replaced with orange.

As a cherry on the cake, now if you insert a new shape, that will also have an orange fill color by default as well.

You can see how this is useful when designing templates: a designer can create something good-looking, and all you have to do is to set the theme to the colors of your organization, and you're done.

How is this implemented?

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

Content controls in Writer: dropdown, picture and date types

Writer already had rich text and checkbox content controls: a new way to set properties on a piece of text, primarily for form filling purposes. This feature now gained 3 additional types: dropdown, picture and date picker types. This improves compatibility with the DOCX format: there are now 5 inline content control types we can now import.

https://share.vmiklos.hu/blog/sw-content-controls2/feature.png
Figure 1. Word-style inline content controls in Writer.

First, thanks to NGI DAPSI who made this work by Collabora possible.

https://share.vmiklos.hu/blog/sw-content-controls/eu.png
Figure 2. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 871498

Motivation

Word users expect to be able to import their document to Writer and experience a matching feature set: form filling is not an exception. Word provides several content control kinds (inline, block, row and cell content controls), this project focuses on inline ("run") content controls.

In the scope of inline content controls, the above linked blog post already described the rich text and checkbox types. In this post, we’ll focus on the new dropdown, picture and date content controls.

You might wonder why content controls are useful, since Writer already has form controls and fieldmarks, which provide something similar. Here are some benefits:

  • Dropdown content controls have a list of dropdown items. Each item is a display-text and value pair, allowing to differentiate between a human-readable string and a machine-readable value. Fieldmarks only handled (machine-readable) values, resulting in document text different from Word.

  • Picture content controls allow the author of a form to pre-format the image before the filler of the form inserts the actual image. Writer already had placeholder fields for images in the past, but that was just text, allowing image format only after insertion of the actual image.

  • Date content controls were emulated with Writer fieldmarks in the past, which created trouble during export, since Word itself doesn’t have a date form-field.

Results

The feature consists of menu items to insert dropdown/picture/date content controls, and then you can interact with the inserted content controls or with their properties:

https://share.vmiklos.hu/blog/sw-content-controls2/menu.png
Figure 3. Menu items to insert drop-down, picture and date content controls.

Drop-down content controls show a dropdown button when you’re inside the content control:

https://share.vmiklos.hu/blog/sw-content-controls2/dropdown.png
Figure 4. A drop-down content control.

This is similar to dropdown fields, just allows display-text and value pairs, not limited to just values.

Picture content controls contain a single as-character image, but you can interact with them: clicking on the content control opens the file open dialog to provide a replacement for the placeholder:

https://share.vmiklos.hu/blog/sw-content-controls2/picture.png
Figure 5. Picture controls.

And these content controls can be saved to ODT and DOCX.

There is also a content control properties dialog, which allows setting if the content controls are in placeholder mode or not:

https://share.vmiklos.hu/blog/sw-content-controls2/properties.png
Figure 6. Content control properties.

It has additional widgets for dropdowns. There is UI to create, update or delete these list items:

As usual, the high-level problem was addressed by a series of incremental commits:

To make this more interesting, Rashesh Padia of Collabora continued exposing this in Collabora Online, see the PR at https://github.com/CollaboraOnline/online/pull/4803.

Dark Style Preference with GTK

Added something to track the org.freedesktop.appearance.color-scheme property as used by the GNOME 42 Dark Style Preference setting. Screencast recorded with the new iteration of GNOME's screen built-in recorder which is quite snazzy.

Interacting with the Review Bot on Gerrit

Have you received “A polite ping, still working on this bug?” message on one of your Gerrit submissions? You can simply send an arbitrary reply to avoid the patch being abandoned within a month. Here we discuss more about Review bot, which is one of the QA (Quality Assurance) tools for the LibreOffice QA team to manage old submissions.

Interacting with the Review bot

You may have received messages from some bots, including Review bot. This bot checks Gerrit to find the older submissions, and abandon the old ones that no one actively work on them.

If it has been several months after the last change on a submission, the bot adds a comment and asks:

A polite ping, still working on this bug?

Then, you can do one of these things, according to your choice:

    1. Reply with whatever you want, and the Review bot will not longer try to abandon your submission. Do this if you want to continue work on the submission.
    2. Mark the patch as “work in progress”. This would be helpful if you want to prevent the bot from monitoring the submission.
    3. Leave it as is. Then, after 1 month your patch will be automatically abandoned with this message:

Abandoned

Abandoning this for the moment due to inactivity. Be aware it can be reopened anytime if you still want to continue working on it. Do not forget to rebase it first.

Even in this case, you don’t have to worry! As the message says, you can simply click on the RESTORE button on the top right of the page to restore the patch and continue working on it.

Please note that if you have restored an old submission, you have to do a re-base to get the latest changes in the LibreOffice code, pushed while your submission was remaining intact. If there is not a merge conflict, you can do this easily by clicking on the REBASE button on the top right of the page. Otherwise, you have to download the patch and resolve the merge conflict manually.
