FLOSS/fund logo

LibreOffice is a volunteer-driven, community open source project, backed by a non-profit entity, The Document Foundation. The vast majority of the foundation’s income is from community support, and we’re happy to announce that FLOSS/fund has made a very generous contribution of USD $100,000 to support the LibreOffice project and community.

FLOSS/fund is from Zerodha, a financial technology company and India’s largest stock broker. It is built heavily on FLOSS (free, libre and open source software) and gives up to USD $1 million to support projects around the world.

Kailash Nadh from FLOSS/fund (and CTO at Zerodha) says:

LibreOffice is one of the most consequential and impactful FOSS projects in the world. We also strongly believe that it has played an important role in enabling adoption of the Linux desktop among regular users. This belief in fact comes from our personal experience of transitioning over 1000 non-technical employees at our organisation to Linux over decade ago.

Many thanks to FLOSS/fund for their support. This helps us to improve our infrastructure, pay developers to work on the software, and organise events to share knowledge. Thank you!

Conference logo

The Salvadoran Lutheran University (ULS) and the Latin American LibreOffice Project community announce the seventh edition of the LibreOffice Latin American Conference.

Previous editions of the LibreOffice Latin American Conference have been held in person in Asunción (2019), Brasília (2022), Mexico City (2023), Montevideo (2024), and Havana (2025). The 2026 edition will bring the event to El Salvador for the first time, further expanding the reach of the LibreOffice community in Latin America.

ULS, the event’s host, has a long history of involvement with Free Software, most notably through the biannual FESOL (Free Software Educational Fair)—an event held for over 20 years that showcases dozens of projects developed by Computer Science students in areas such as web systems, databases, robotics, and video games, among others.

The conference will take place on November 27 and 28, 2026, with the aim of bringing together users and contributors to share knowledge and experiences related to LibreOffice.

Guest speakers from Mexico, Spain, Brazil, France, and Taiwan will present topics ranging from tutorials on using the applications to ways of collaborating with the project. The schedule will be announced soon on the official event website:

FrOSCon logo

FrOSCon is an annual conference dedicated to Free and Open Source Software (FOSS), held in Sankt Augustin (near Bonn), Germany. And this year, the LibreOffice community was there! We hosted a booth featuring information flyers and merchandise, including stickers, pens, coasters, and more.

We engaged in many substantive conversations at the booth about LibreOffice as a project and its specific features. We also discussed TDF’s development plans for web and mobile platforms and encouraged people to get involved in these areas.

Many visitors stopped by saying, “Of course we use LibreOffice” – often contrasting it with Microsoft Word, which is the “standard” or widely used option in corporate environments. We also frequently heard comments like, “I’ve/we’ve already donated.” Clearly, there is a widespread willingness to contribute financially to software that is both high-quality and genuinely free.

Community members at the stand

Visitors were happy to take home coasters or small stickers. LibreOffice supporters often like to place these items where Microsoft-oriented users can be found.

Alongside the project booth, Andreas Mantke gave a presentation in German titled “Where is LibreOffice Headed?” (Wohin führt der Weg von LibreOffice?), in which he discussed the project’s planned development ideas for web and mobile and answered questions from the audience.

We look forward to being at more events in the coming months!

avtor: Italo Vignoli (The Document Foundation)


Danes, 19. septembra, je Dan svobode programske opreme, poseben dan, ki ga skupnost prostega programja vsako leto praznuje tretjo soboto v septembru po vsem svetu.

To je dobra priložnost, da si ogledamo LibreOffice iz perspektive, ki se pogosto jemlje za samoumevno: ne gre za to, kaj programska oprema počne, ampak za to, kaj omogoča uporabnikom in česa jim ne vsiljuje.

Prosta programska oprema je opredeljena s štirimi svoboščinami. LibreOffice jih vse zagotavlja, iz njih pa izhajajo številne druge svoboščine, ki so pomembne za vsakogar, ki piše pismo, pripravlja proračun ali predstavlja projekt.

Štiri svoboščine

LibreOffice se razširja pod javnim dovoljenjem Mozilla Public Licence 2.0, ki vsakemu uporabniku zagotavlja štiri svoboščine, ki opredeljujejo prosto programsko opremo:

  1. svobodo, da program uporablja za poljuben namen, brez vsakršnih omejitev;
  2. svobodo, da preuči, kako program deluje, zahvaljujoč dostopnosti izvorne kode;
  3. svobodo, da program prilagodi lastnim potrebam, tako na individualni kot na organizacijski ravni;
  4. svobodo razširjanja kopij programske opreme, vključno s spremenjenimi, da lahko tudi drugi uporabniki izkoristijo njene prednosti.

Svoboda lastništva nad lastnimi dokumenti

Dokument pripada njegovemu avtorju le, če format, v katerem je shranjen, ne pripada komu drugemu. LibreOffice kot svoj izvorni format uporablja Open Document Format (ODF): standard ISO/IEC, ki je bil razvit v okviru organizacije OASIS v preglednem in v celoti dokumentiranem postopku, ki ga nobeno posamezno podjetje ne more enostransko nadzorovati ali ga spreminjati.

To pomeni, da bo dokument, danes shranjen v formatu ODF, še čez dvajset let berljiv, bodisi s paketom LibreOffice bodisi z drugo programsko opremo, ki podpira ta standard. Za posameznike je to vprašanje praktičnosti. Za javne organe, ki imajo dolžnost hraniti dokumente in komunicirati z državljani, ne da bi jih prisilili v nakup določene programske opreme, pa je to načelno vprašanje.

Svoboda, da svoje podatke ohranite zasebne

LibreOffice ne zbira podatkov o svojem delovanju in od vas ne zahteva, da si ustvarite račun. Dokumenti se ustvarjajo, urejajo in shranjujejo na računalniku uporabnika ter tam ostanejo, razen če se uporabnik ne odloči drugače. Ni obvezne povezave z oblačno storitvijo, na oddaljenem strežniku pa se ne ustvari noben uporabniški profil.

Svoboda dela brez motenj

LibreOffice ne prikazuje oglasov in uporabnikov ne poziva k sklenitvi naročnine ali prijavi na premijski paket. Vmesnik je zasnovan za podporo delu uporabnikov, ne pa za prodajo dodatnih storitev.

Svoboda odločanja o umetni inteligenci

LibreOffice ne vsebuje nobenih funkcij generativne umetne inteligence. Uporabniki, ki jih potrebujejo, jih lahko dodajo prek razširitev in izberejo, katero storitev bodo uporabljali, vključno z modeli, ki se izvajajo lokalno, medtem ko uporabniki, ki jih ne potrebujejo, ne bodo ničesar zamudili, saj ni ničesar, kar bi lahko zamudili.

Svoboda izbire platforme in jezika

LibreOffice deluje v sistemih Windows, macOS in Linux, dokumenti pa se med sistemi brez težav prenašajo. Uporabniški vmesnik je na voljo v …

por Italo Vignoli Hoy, 19 de septiembre, se celebra el Día de la Libertad del Software, una fecha especial que la comunidad del software libre conmemora cada año, el tercer sábado de septiembre, en todo el mundo. Es una buena oportunidad para analizar LibreOffice desde una perspectiva que a menudo


Friday
18 September, 2026


face

Today, 19 September, is Software Freedom Day, a special day that the free software community celebrates every year on the third Saturday in September all over the world.

It is a good opportunity to look at LibreOffice from a perspective that is often taken for granted: not what the software does, but what it allows users to do and what it does not impose on them.

Free software is defined by four freedoms. LibreOffice guarantees all of them, and from these derives a range of other freedoms that are important for anyone writing a letter, preparing a budget or presenting a project.

The four freedoms

LibreOffice is distributed under the Mozilla Public Licence 2.0, which guarantees every user the four freedoms that define free software:

  1. the freedom to run the programme for any purpose, without any restrictions whatsoever;
  2. the freedom to study how the programme works, thanks to the availability of the source code;
  3. the freedom to modify the programme to suit one’s own needs, both at an individual and an organisational level;
  4. the freedom to redistribute copies of the software, including modified ones, so that other users may also benefit from its advantages.

The freedom to own your own documents

A document belongs to its author only if the format in which it is saved does not belong to someone else. LibreOffice uses the Open Document Format (ODF) as its native format: an ISO/IEC standard, developed at OASIS through a transparent, fully documented process, which no single company can control or modify unilaterally.

This means that a document saved today in ODF format will still be readable in twenty years’ time, either with LibreOffice or with other software that implements the standard. For private individuals, it is a matter of practicality. For public authorities, which have a duty to preserve documents and to communicate with citizens without forcing them to purchase specific software, it is a matter of principle.

The freedom to keep your data private

LibreOffice does not collect data on its operation, and does not require you to create an account. Documents are created, edited and saved on the user’s computer, and remain there unless the user decides otherwise. There is no mandatory link to a cloud service, and no user profile is created on a remote server.

The freedom to work without distractions

LibreOffice does not display adverts and does not prompt users to take out a subscription or sign up for a premium plan. The interface is designed to support users’ work, not to sell additional services.

The freedom to decide on artificial intelligence

LibreOffice does not include any generative AI features. Users who need them can add them via extensions and choose which service to use, including locally running models, whilst users who do not need them do not have to miss out on anything, as there is nothing to miss out on.

The freedom to choose platform and language

LibreOffice runs on Windows, macOS and Linux, and documents transfer …

por Italo Vignoli LibreOffice 26.8 incorpora soporte básico para importar y exportar una serie de tipos de gráficos que Microsoft Office incluye en los archivos OOXML: gráficos de caja y bigotes, embudo, Pareto, radial, mapa de árbol y cascada. LibreOffice no puede mostrar ni editar estos gráficos, pero sí los


face

LibreOffice 26.8 adds basic support for importing and exporting a range of chart types that Microsoft Office includes in OOXML files: box-and-whisker, funnel, Pareto, radial, treemap and waterfall charts. LibreOffice is unable to display or edit these charts, but it does recognise them, informs the user that the chart type is not yet supported, preserves the underlying definition unchanged, and rewrites it when the file is saved.

At first glance, this appears to be an admission of incompleteness, whereas it is actually an example of what implementing a proprietary format entails when the aim is interoperability – for the benefit of users, rather than a commercial strategy that treats users as mere tools.

What happened

Microsoft added these chart types to Office from 2016 onwards, storing them in a namespace generally referred to as ‘chartex’. The namespace is not part of the ISO/IEC 29500 text approved as an international standard, but is documented separately in Microsoft’s extension documentation.

This is entirely legal and perfectly normal commercial behaviour: a vendor improves its product and the file format evolves accordingly. The consequence, however, is that the format in everyday use is no longer the one that was standardised. The ISO number continues to be cited in tender documents and policy documents, but the files being exchanged are different.

For any implementer other than the vendor, this creates a permanent state of delay. This is not a one-off gap to be bridged with sufficient effort, but a structural delay, as the specifications are in the hands of a vendor that does not publish its release schedule, with priorities defined according to commercial criteria.

Three possible responses

An office suite that encounters a chart it does not recognise has three options:

  1. It can reject the file. This is an honest but pointless solution: the user is left with a document they cannot open and concludes that the software does not work.
  2. It can discard what it does not understand. The file opens, the chart disappears, and the user only realises this when the document is forwarded to a colleague and the chart is no longer present. This is the most damaging outcome, as the loss occurs silently and the blame falls on whoever opened the file last.
  3. They can retain what they are unable to display. The user is informed that this type of chart is not supported, so they see a placeholder rather than a blank space, and the underlying definition remains intact when the document is transferred from one application to another. The document is restored in full when returned to the source application.

LibreOffice 26.8 adopts the third option, the only one of the three that respects the fact that the document belongs to the user rather than to the software – or, indeed, to the company that develops the software.

Unfortunately, there is a limitation, and this is an exception. Charts with regional maps contain extensive geographical information that LibreOffice is unable to preserve. The chart type survives …

LibreOffice Expert magazines

A few weeks ago, Linux New Media released an updated version of its “LibreOffice Expert” magazine, which contains tutorials, tips and tricks about the office suite. And some articles were contributed by members of the LibreOffice community! The magazines come with DVDs that include LibreOffice for Linux, Windows and macOS, alongside extra templates, extensions, videos and guidebooks.

We have some copies to give away, for schools, universities, libraries and local communities. Ideally, we’d like to get these magazines out to places where internet connections aren’t always available – so that the users can really benefit from the DVDs.

So, if you can help us to distribute these magazines, drop us a line! Please note that we have 50 copies in total and can therefore only send a maximum of five copies to any one place, to make sure many communities get a chance. When you contact us, please include this information (any requests without information cannot be fulfilled and will be ignored):

  1. What you want to do with the magazines
  2. How many you want (1 – maximum 5 copies)
  3. The address to which we should post them

Include all of that that information in an email to us with subject line “LibreOffice Expert for communities” and let’s see what we can do!

por Italo Vignoli Las novedades más importantes de LibreOffice 26.8 están relacionadas con los sistemas de escritura. Vale la pena explicar qué se ha hecho y, sobre todo, por qué se ha hecho, ya que detrás del trabajo de los desarrolladores existe una decisión importante. Qué se ha hecho Writer


face

The most significant new features in LibreOffice 26.8 concern writing systems, and it is worth explaining what has been done and, above all, why it has been done, as there is an important decision behind the developers’ work.

What has been done

Writer now automatically detects the paragraph direction when opening or pasting documents or plain text, without requiring the user to set it manually.
Spaces at the end of a line are positioned according to the paragraph direction rather than that of neighbouring characters, which corrects a long-standing issue with how line breaks are handled in mixed Arabic and Latin texts.

Object resize handles now work correctly in right-to-left CJK documents and in vertical documents.

Bidirectional control characters are displayed alongside other formatting marks, so that invisible directional substitutions can be both viewed and edited.

The semantics of paragraph alignment have been revised. New documents use justified alignment by default rather than left-justified, and changing the paragraph direction no longer overrides the explicitly set alignment. This is a small change with a significant impact, as a document written in Arabic and one written in English can now share a template without conflicting.

In Calc, when typing text from right to left into an empty cell, the direction of that cell is now set automatically.

LibreOffice Math has gained functions and operators for the N’Ko and Adlam alphabets, along with left-pointing vector arrows and harpoons for right-to-left formulas, without which mathematical notation in these two alphabets cannot be composed correctly.

Finally, the names of fonts registered in languages other than the interface language are now recognised, so that a document created in a Japanese or Russian installation is displayed using the fonts chosen by the author rather than substitute ones.

Why this is unusual

N’Ko is a writing system devised in 1949 by Solomana Kanté for the Mandingo languages of West Africa. Adlam was devised in the late 1980s by two teenage brothers, Ibrahima and Abdoulaye Barry, for the Fulani language, which until then had been written using adapted Arabic or Latin scripts – an inadequate solution. Both scripts run from right to left, are used by populations numbering tens of millions of people, and have been added to Unicode over the last twenty years.

Neither language represents a market. The native speakers concerned do not, as a whole, constitute a customer base large enough to justify the time spent on development based on a commercial analysis. No tender process, anywhere in the world, has led to the completion of this work. No corporate client has requested it. No competitive pressure has made it necessary.

The contributor who added support for N’Ko and Adlam to LibreOffice Math is a volunteer.

Much of the work on bidirectional text was carried out by a developer employed by The Document Foundation, which is funded by donations.

The renaming of the CJK text grid option, so that it correctly referred to the genkō yōshi handwritten grid used in Japanese typesetting …

If you don't know what is dynamic arrays, then just read this article https://exceljet.net/articles/dynamic-array-formulas-in-excel.

Note, dynamic array's functions like UNIQUE, FILTER, SORT, etc. were already implemented early. But other new general dynamic array features were added to LibreOffice Calc only now into current master that will be 27.2 release in next year.

Let's say big thanks to Collabora's developers for it, because all work was made for Collabora Office and then Xisco Fauli copied all patches to LibreOffice project (The source code license allows it, because it's the same MPL 2.0 on both sides).

You can try the new features using master daily builds for your OS by the link.

por Heiko Tietze A principios de este año realizamos una encuesta sobre LibreOffice Base. Al igual que en los cuestionarios sobre LibreOffice Draw (véase la primera y la segunda publicación del blog) y sobre LibreOffice Calc, preguntamos acerca de los casos de uso, las características más importantes y los principales


face

Earlier this year we ran a survey about LibreOffice Base. Similar to the questionnaires about LibreOffice Draw (see first and second blog post) and LibreOffice Calc, we asked about use cases, the most important features, the pain points – and what users expect in the future to support development and to gather ideas how the user interface and workflow can be improved. In total, 455 participants completed the questions. Thanks a lot to everyone who took the time!

Demographics

As usual, the survey is heavily biased. The attendees self-estimate their expertise above the average, run the application more frequently, and show a different distribution in operating system usage compared to regular users.

Applications

To start off, we asked what tools they use. We included Spreadsheet Tools to also cover users who do not actually use a database, but think of a spreadsheet as kind of data storage. Participants responding None, obviously not managing any database, got a different follow-up question.

What tools do you use to manage databases?

Features

To trigger the idea of the following open questions, we asked about the importance of different features. Unlike the large number of functions in other modules, Base offers queries, reports, forms, tables, etc. which are all essential for the work with databases. Therefore we collected some features that may or may not be relevant for a sub-group or have room for improvements.

How important are these features for you?

What is your use case for the database management system?

People understand the question differently, and reply very short or rather verbosely. The answers may point to a professional environment if “payroll information for up to 10000 people” is mentioned, over SME’s processing order management, production count, and shipment status, to obviously private usage. The following attempt to categorize the answers cannot do justice to the variety of all replies:

  • Catalogs/Inventory: In-house Bakery, Receipts, Music/Books, CD/DVD, Musical scores. Plant samples, Publications/Scientific research, Health data
  • Web/Software: Backend storage, Software development, Websites, Managing SQL
  • ERP/Finance: Order management/Production count/Shipment status, Invoicing, User data, Cost management, Expenses,
  • Storing addresses and mail merge processing

For example:

“I use it mostly as place to store sensitive customers data. But since I have small quantities of information, I switched to LibreOffice Calc, which files can be also locked with the password.”

“Smaller business applications in the freight forwarding and logistics sectors, such as fleet management, warehouse management, category management, and invoicing.”

“Managing geospatial information with PostgreSQL/PostGIS and creating reports with the information from the attribute table using LibreOffice Base/Writer.”

“Storing data when it gets too big/slow for a CSV file for personal or internal work (engineering) projects.”

In your opinion, which LibreOffice Base features (if any) need improvement the most, and why?

The majority asks for improvements to the user interface with less clutter and a more attractive design. The workflow and user experience should become either simplified or more powerful, depending on the expertise and the scenario …

The NotebookBar (NBB) or tabbed interface is an alternative user interface for LibreOffice. In the second part of this series, I explain the way the NotebookBar takes icons and text to create the final output that you see on the screen.

Creating NotebookBar is LibreOffice Code

Currently, the NotebookBar is not exactly like the other UI files that in LibreOffice with weld mechanism. In the first part of the series of blog posts on this topic, I discussed the custom widgets in notebookbars and how to edit them using Glade.

The custom widgets rely on C++ code, especially for sizing and other characteristics. For example, Priority Merged Horizontal Box (sfxlo-PriorityMergedHBox) is a “horizontal box hiding children depending on its priorities”. It needs C++ code to implement the priority display of the children. If you search for it in C++ files, you will reach builder.cxx:

$ git grep -l sfxlo-PriorityMergedHBox "*.cxx"
vcl/source/window/builder.cxx

The above file is a huge > 100 KB C++ source code  that handles NotebookBar custom widgets, but also handles every other VCL widget.

The other parts of the relevant code for the NotebookBar resides in below files. Search for both “Notebookbar” and “notebookbar” in C++ files:

$ git ls-files "*otebook*cxx"
sfx2/source/notebookbar/NotebookbarTabControl.cxx
sfx2/source/notebookbar/SfxNotebookBar.cxx
vcl/qt5/QtInstanceNotebook.cxx
vcl/qt6/QtInstanceNotebook.cxx
vcl/source/control/NotebookbarPopup.cxx
vcl/source/control/notebookbar.cxx
vcl/source/window/NotebookBarAddonsMerger.cxx

Icons in Notebookbar

If you open the NotebookBar UI for LibreOffice Writer or other components like Calc, etc., what you see lacks two important things: icons and text.

Notebookbar widgetsNotebookbar widgets

First, let’s look into icons. The icon files come from the set of icon themes that are available with LibreOffice. The icon theme of LibreOffice is configurable, therefore you do not see some specific LibreOffice icon in the design. That makes the work of UI designers harder, but lets LibreOffice choose among different icon themes.

You may find more information in the icon-themes/ module README.md file, which describes how to create new icon themes, and how to link the icons to specific icons via .xcu files. For example, in officecfg/registry/data/org/openoffice/Office/UI/CalcCommands.xcu you see:

<node oor:name=".uno:OpenFromCalc" oor:op="replace">
    <prop oor:name="Label" oor:type="xs:string">
        <value xml:lang="en-US">~Open...</value>
    </prop>
    <prop oor:name="Properties" oor:type="xs:int">
        <value>1</value>
    </prop>
</node>

This is defined for the UNO dispatch command, .uno:OpenFromCalc, which opens a file for Calc. The complete list of UNO dispatch commands is available here:

For each command, two icon sizes are created, one small and one big icon. lc_<command name>.png and sc_<command name>.png, if not in SVG format. At first, one should add the icons for a new command to the colibre theme, in order to be usable also with other themes.

Here, the filenames will be lc_openfromcalc.png and sc_openfromcalc.png, which are available …

Berlin, 26. avgust 2026 – TDF (The Document Foundation) danes objavlja izid LibreOffice 26.8, nove osrednje izdaje brezplačnega in odprto-kodnega pisarniškega paketa, ki je takoj na voljo za Windows, macOS in Linux v več kot 120 jezikih. Izdaja je delo 206 sodelavcev, od katerih jih je 155 prostovoljcev.

LibreOffice 26.8 se osredotoča na tri področja: tipografsko kakovost tega, kar s paketom ustvarite, nabor sistemov pisanja, ki jih pravilno obvladuje, in zvestobo, s katero dokumenti preživijo izmenjavo z drugimi pisarniškimi paketi.

Sistemi pisanja


Največ opravljenega dela v LibreOffice 26.8 naslavlja dvosmerno in kompleksno besedilo. Writer zdaj samodejno zazna smer odstavka, ko odprete ali prilepite dokumente ali navadno besedilo. Prelom vrstic postavi presledke konca vrstice glede na smer odstavka in ne glede na sosednje znake. Ročice za spreminjanje velikosti predmetov se pravilno vedejo v dokumentih CJK, ki se pišejo od desne proti levi in navpično. Dvosmerni kontrolni znaki so zdaj vidni poleg drugih oznak za oblikovanje. V programu Calc se z vnosom besedila od desne proti levi v prazno celico samodejno nastavi smer te celice.

Semantika poravnave je bila ustrezno spremenjena: novi dokumenti imajo privzeto poravnavo na začetek in ne levo, spreminjanje smeri odstavka pa ne odraža več eksplicitno levo ali desno poravnanih odstavkov.

Program Math je pridobil poimenovane funkcije in operatorje za pisavi N'Ko in Adlam, ki se uporabljata za mandejske jezike v Zahodni Afriki in za fulanski jezik, skupaj z levo usmerjenimi vektorji in harpunami za formule od desne proti levi. Možnost besedilne mreže CJK je bila preimenovana, da odraža njeno dejansko funkcijo, in sicer omogoča mrežo rokopisa genkō yōshi. Imena pisav, zabeležena v jezikih, ki niso tudi jezik vmesnika, so zdaj razrešena, zato se dokumenti, napisani drugje, prikažejo v pisavah, ki so jih izbrali njihovi avtorji.

Nič od tega opravljenega dela nima tržnega učinka. Prizadeti jeziki predstavljajo majhne trge ali pa sploh nobenega. Vključeno je, ker pisarniški paket, ki služi le jezikom s kupno močjo, ni infrastruktura, temveč izdelek.

Tipografija

Program Writer uvaja sestavljalnik odstavkov, algoritem postavitve, ki uravnava razmik med besedami po celotnem odstavku, namesto da bi optimiziral vsako vrstico posebej. Enovrstični, pohlepni pristop, ki ga uporabljajo urejevalniki besedil, je standarden že od uvedbe tehnologije in ustvarja poravnano besedilo, v katerem se izmenjujejo prenatrpane in redke vrstice, kjer koli se dolge besede približajo prelomu.

Različice tipografij OpenType so zdaj izvorno podprte, kar omogoča rabo spremenljivih pisav, kot so bile zasnovane, vključno z osmi, ki prilagajajo kontrast in razmerje črk velikosti, na katero je besedilo nastavljeno.

Poravnava mreže osnovnic zdaj deluje pravilno za besedilo znotraj okvirjev, mrežo pa je mogoče prikazati med urejanjem z nastavljivo barvo.

Izmenjava dokumentov

LibreOffice Chart zagotavlja osnovno podporo za krožno pot za novejše vrste grafikonov, ki jih Microsoft Office zapisuje v datoteke OOXML: grafikon kvartilov, lijaki, razvrščeni histogram (pareto), sončni izbruh, drevesni grafikon …

The city has always carried the same caveat: it is a model, it parses no SQL, and no Firebird code runs in your browser.

Electric Firebird (mariuz/electric-firebird on GitHub) compiles the Firebird database engine to WebAssembly, following the same approach PGlite took for PostgreSQL. The goal is to let Firebird run both server-side (Node.js) and fully client-side in the browser, with no server round-trip required for queries.Highlights:Two backends: a native Node.js implementation (via the Firebird Embedded Server

Correction (added 9 August 2026): the section below headed &ldquo;A synchronous replica that dies hangs commits&rdquo; is wrong. Dmitry Sibiryakov pointed this out on firebird-general, and the source confirms it. In src/jrd/replication/Publisher.cpp, checkStatus() is called with canThrow = false on the commit path, so it cannot throw; disable_on_error (default true) instead clears the replicating
