 First of all, my name is.... and I'm the author of the home spell... Spehrchecker and some Libre... other Libre office components... for example Libre logo. It's a little existential but... it's I think, quite interesting. and last months I worked it for... big, hungering IT company, NIS, as Gabor mentioned in his people's presentation. So I will speak about these developments, interoperability developments, too. So, but, yes, the first picture, I didn't mention, but this is the Russia's airport with this interesting statue, and my second slide showed that this is a near 70 years old illustration from a famous Belgian cartoon, the Tintin, the Adventures of Tintin, and the text of this, maybe you can read it, so Tintin, the small person in the middle of the picture so that he is the first man in the moon. And this is the revised version from 1969, with a little rumor. So, the aim to show these pictures is that the art can inspire, can inspire, for example, children, but also liberal office development, too. So, one of the topic of my presentation, similar thing, I try to inspire or show inspiring thing in liberal office. So, my agenda, first I will show and I will try to demonstrate the work of liberal logo. All of my topics in this presentation were already documented in my previous presentation in Tirana, the liberal office conference, and you can find these presentations. So, I will try to demonstrate instead of showing more and more and more slides from my previous but similar presentations. So, a new thing related to liberal logo that in April will be published a new children's workbook for German schools. And that is mentioned in Tirana in October. I show some book covers, but this is a book series and new one, this one has got a cover. So, you can check it, the author is Mirek Hans, a German teacher. And his examples in this book is related to liberal office, too, because liberal logo is a little bit hidden component of liberal office. And the news about liberal logo related to this German textbook and related to the research of the Florence University, where liberal logo was used in the teacher education, and kindergarten, nursery, education, too. So, in November or in October, I made several interesting improvements in liberal logo, mostly fixes in the user interface, but I added unit tests to the code, liberal office code related to liberal logo. So, now in every full building of liberal office, we'll check liberal logo, too. So, it's quite useful if you want a stable liberal logo in liberal office. And on liberallogo.org, it's a homepage of liberal logo. You can read about the results of this interesting results of this unit testing. For example, Stefan Bergman, red head developer, found a new reg exchange in Python 3.6 related to liberal logo, too. Python 3.7, if I remember. So, I'll try to show something. Yes, this is in the picture. No, sorry, that is not something. I will try to set. Yes, this is liberal office writer with a new page. And there is a toolbar here. This is a logo toolbar you can found in the toolbars menu. Maybe I will show it. And you try first enable this toolbar. It's a little bit hidden, because in this little machine, it tries to put in the first line so that you can find it if you try it. And if you click on the run button in an empty document, you will get an example program. And it's a real empty document. Yes, this was not so empty, it seems. And I will try to enlarge these letters. So, you can see the English version of the liberal logo commands. One of the interesting features of liberal logo is very well localized. In fact, all liberal logo commands in the putl server, the translation center of liberal office. So, maybe if your language hasn't supported liberal logo yet, you can try to translate the liberal logo commands in a common interface with that page of liberal office. So, and run again. This little turtle pointer will draw vector graphics. So, one of the, yes, in this example, I will show that this is a real vector graphics. So, you can modify in standard way of liberal office user interface after selecting the object, yes, for example, here. We can make new programs, or, in fact, we can use this input box in this menu. For example, forward will move the turtle. I will clean the image forward, for example, 200 points. This is a typographical point. So, if you print your vector graphics drawn by liberal logo, you will get correct measurements. You can, for example, use millimeter, or inch, two, or centimeters. But it's a little bit too big for 200 centimeters. But if I write, remember, the maximum of the page size of liberal office is three meters. So, you can use 300 centimeters, if you want. For example, five centimeters forward, and write 18. I will center the turtle, and I may enter. Yes, I will try to 100, for example, write 100 degrees. And, like a flower, like symbol, you can use automation, a loop, for example, repeat this command, and fill the result. This is vector base, so there is no, you don't need to center the turtle inside of a shape, because the shape is a real vector shape in liberal office. So, fill command will fill the last object drawn by liberal logo. So, yes, we get an interesting shape after, and I will modify a little bit, or switch off this, and select a better color, or, in fact, the default setting of the filling color is a little bit, the 50-100 visibility transparency, sorry. So, we can switch off these two, no transparency. For example, we can choose a lighter color. As a normal shape in liberal office, double click on it result cursor, so you can add the text too. It's sometimes useful, sometimes useful in the education, or making new illustrations. In liberal logo.org, you will find, for example, viki media commands, extensions, or illustrations. Sorry, my, I will try to, yes, it's correct. I will speak about spelling, checking too, so, sorry, my mistake. I will try to show some more complex things too. For example, one of the fixes of the liberal logo, it's fixing this magic wand, pressing this magic wand, and for these shortening, abbreviations of the commands, for example, FD, will transform to uppercase, and not a full form, or not an abbreviation. And, for example, a cycle, a four cycle, maybe it will, yes, there is a problem in the code, repeat the correct command, yes, try to. So, we get a triangle, and we can combine the different things, for example, a circle somewhere here, and, yes, modify the field color, for example, maybe green, then color green, and pen size 13, this is the result. We can clear the screen with command two, and using this home command, and if you try to modify the result, we got parts, because the circle command will break the line. So, if you want to generate a single shape, we can use the picture command of the liberal logo, abbreviation only pick, but I will, I will, yes, so, there is an error, my, and this line, and here, too. Yes, no, you can see this is a single shape, because liberal logo uses the grouping feature of shape handling of liberal office. So, this is an interesting feature, to reuse the result of liberal logo drawing. We can embed this picture, for example, write six degrees, we can use, for example, the degrees signed, too. Maybe in the school, it's a little bit useful, and there is a new picture here, and a new repeat, and two, yes, and this is the atomium symbol of Brussels, and yes, this is a single shape, so you can use, or you can easily, it's called GDI illustration, this is kind of factor format of liberal office, with this format you can easily transform the result, or enlarge, or copy to draw, et cetera, and I can show that, with the ungroup command, you will ungroup this result, and you will get the six smaller, grouped shape here. So, sorry for that, sorry for, but with undo, I can fix the symbol again. So, if I'm afraid I have no too much time, so I will show other interesting things here. So, yes, okay. So, other fixes here, that is a new parser, instead of the heuristic method, you know, every complex logo expression will be handled correctly, so it's also useful, if you want to make more complex logo programs using different functions, focus on using Python functions, it's possible to combine Python and liberal logo, and with this fix it's more easier and more correctly. Unfortunately, I can show you that there is a dragon curve example on the LibreLogo.org homepage. Using the dragon curve, it's a recursive algorithm using two procedures, and before this fix, it wasn't possible to write the procedure names without parenthesis, so it's also a useful thing if you want to teach fractals or recursion, et cetera. And the other topic, the language technology, if you have a German-like language, for example, not only German, but Dutch, for example, or aglutinative languages like Hungarian or Turkish, no, it's spell checking, it's much faster in LibreOffice because the new version of who spell spellchecker has a multi-level time limitation, keeping the good suggestions, but instead of five seconds, for example, or more, no, there's a maximum half a second or less time for the suggestions. So it's more comfortable. So the new number text is a new library. If you check the numbertext.org, you will see this tool. Maybe I'm afraid a little bit slow, so I can show you, but I will try in the last five minutes. So, and there is a new native number formatting format, this netnum 11, which is, you can, and with the feature that the data files of this number text library originally used only for chapter numbering with number names, one, two, or first, second, et cetera. But with this simple text-level disruption of the formatting functions, you can add very special extensions for numbering. The default functions is not only these ordinal and cardinal numbers in this library, but adding currency symbols or currency names. For example, the origin of the history of the number text is a backtext function of the Microsoft Excel and the OXMS standard. The backtext is a function to convert cardinal numbers, thank you very much, to tie, tie, but the type currency is but, and converting the tie number names. So it's a very limited for an international standard. Number text has no such limitation. It can support much more languages recently, near 40 languages. So, with netnum, you can add special ethical affixation, et cetera, support to LibreOffice. So it's, I mentioned the extended slides. It's quite interesting. For example, in the Turkish or other languages, because, for example, in 2019 or 2018 have different affixes. For example, in 2019 or in 2018 in Hungarian, Kéte zeptizem, Ben and Kéte zeptizem was a ban. So there is a vowel, harmony-related variation. The news in LibreOffice, so about in the last five minutes about this development, we, in the last half a year, we fixed near 60 bucks, interoperability bucks and real, without interoperability, simple or plain LibreOffice bucks, too. So instead of showing the summary, I will show a few fixes in, if I write, yes. And this is a daily build of LibreOffice. So, sorry, I will switch to the LibreOffice window if I can. And so, for example, one of the main topic of the last developments is the change tracking. So I will show a simple texture here and I will switch the change tracking and here I will delete or remove text. And if I, maybe I can show you in the old version of LibreOffice, the similar thing. So I will switch here, too. Yes. And yes. And not a big problem, but most of the, our problems are small, but sometimes it's very hard to fix a small buck, too. And if you click on the next change button, LibreOffice selects the next change in the window, but the problem is, you cannot add the comment on the change. Why? Because it's a bug of LibreOffice. If you click on text, for example, you can add a new comment. Or if you select this from right to left, you can add a comment. But if you select with the mouse from, I'm sorry, from left to right, you can add a comment in LibreOffice, but here is the new version. And in this version, this is a, yes, you can add a comment, for example. No, it's a useful fix, for example. And a bigger problem. And in fact, the solution is a better workaround that in this old version, if you select a word and you made a format change, formatting change here, this change is, or bold letters, et cetera. In fact, the problem, I will show you, it's in you, you will see, yes. If you select the formatting change and instead of accepting to try to react, you cannot react this change here, because it's related to the format. In fact, the next version of open document will handle this kind of problems correctly, but no, it's not possible. So, you can react, and if you click on the react all, instead of reacting this formatting change, LibreOffice secretly will accept these changes. So it's a hard or serious thing, dangerous thing. For example, in that, if you try to use LibreOffice among Microsoft Office or something, things, but this is the new version of the daily version of LibreOffice, and if you try to do the same thing, yes, the next speaker gave me a few minutes. So... Sorry. Sorry. Ok, ok, ok. So, only I try to react all, but the new version doesn't remove this kind of only formatting change, but the button try to notice that this is a problem for LibreOffice. So instead of react, there is a react clear formatting, react or clear formatting button title. So if you try to react this or clear, in fact clear formatting and click on this button, in this case it was a real react of the change, because originally there was no any other formatting here. We are working similar things and maybe I will show more examples in the five minutes sections if it's possible yet. Thank you for your attention.
