Hello There, I have just received The Lazarus Handbook, what a beautiful work ! I was very impressed by the first glance I had with the pdf version, the text is very rich and full of informations, also well structured, but I didn't expect the physical books to be such a pleasure to look at and handle.Thank you for this beautiful job, you have done something rare by the time being. It is going to be a pleasure to work with these manuals, and they will last for long. Have a nice day, keep doing well, thanks a lot,
Just received my copy of the Lazarus Handbook. The books are beautiful. Real craftsmanship.
A pleasure to read. 
Thank you. You and everyone involved have delivered real craftsmanship. Best regards,

Dear Sir, i've just received the *Books* (pre-ordered in 2018) well, they are really nice. They are quality books (as you said back in 2018) and looking at all others IT books i already have, they are the highest quality and finish and by far so many thanks for all this and they are worth any penny. Now I don't know what will be next Books 1 & 2 but could this be the beginning of a "Pascal Encyclopedia". Looking forward a book 3 ... covering pas2js ? Thanks again and kind regards from France
Thank you for keeping me informed about the progress of the Handbook and for making draft PDFs available during its gestation. I am now pleased to report that the printed version has been safely delivered to me. I realize that the production of the book has been a huge effort, and I would like to congratulate you and the other authors for a piece of work that you should all be very proud of. I look forward to using it as my go-to reference now and in the future.
Kind regards N.A. (UK)

    • I am not sure about that. We are working with about 7 people on this project. One of the main authors wasn’t able to do his part because of personal reasons. He has started it now,
      and I am trying to help. But it will probably not yet be completely available because we have little time left so it will be later…

      • Yes we are adding new parts to it Michael has added some extra,
        I am working on the new file. Probably over the weekend I will update it to the newest version so you can have the latest PDF.
        The development and writing of the book is now top-prio.
        The next magazine issue will be done after that.

  • dag Defled,

    Ik kan je niks bereiken en je geef nooit antwoord op mijn whatapp.
    Ik wou die boek kopen en maar ik kan niet compleet invullen.
    Die reageert iedere keer weer naar boven wat ik fout gemaakt hebt.
    Graag wat reactie van u.

  • Well beyond a year and a half past the originally proposed release date for this book and it still isn’t finished. If this were to be a free book, I wouldn’t have an issue with it. Don’t look a free gift horse in the mouth, right? However, though I am not one of them, many people have prepaid money for this book. Therefore, being so far beyond its due date with only monthly drivels of chapters in PDF form is not an acceptable resolution to paying customers. As excited as I was for this book upon its initial announcement, I have now completely given up on it.

    • We cant simply create the chapters without writers. We are working very hard on it and even a new version (12) is coming.
      We are very close to the final result but still not yet ready. We will try to finalize it in February 2020.
      It will be about a thousand pages.(Planned was 650.) We are trying to create the best book that is possible by the best writers.
      I agree that we underestimated the enormous task. And apologize for that.
      But please be a bit more patient. We had a lot of authors starting, but after a while stopped.
      So we needed to find other people for that. But we heave taken the task to take over all those tasks.
      I agree it took far more time then I expected and are working on it very hard.
      Please accept these apologies.

  • It is ok so. Because with the PDF’s between I can take for learning and the finished book will be a very good one. I like this more as to have a finished book and some instructions are incompleted. Good luck for your very good work. (I know, your team have not thinked how efficient and powerful Lazarus is now and how much there is to explain 😉 ).

  • The delay is somewhat understandable. The lack of communication about it, not so much.

    Looking at the Handbook Installation section for macOS, it cannot even get the operating system name correct. It is macOS (and was previously marketed by Apple as Mac OS X and OS X) and is not “MacOS” or “MacOS X”.

    Additionally, it looks to me like the macOS information was taken from the Lazarus Wiki and is now well and truly out of date (eg Xcode is available in the App Store, you no longer need to login to the ADC website to get it).

    Carbon is not just “deprecated” but completely removed from the current version of the macOS operating system. Many file paths are now no longer writeable by any users, including Admin, due to the read-only system volume.

    The dialog shown for non-signed and/or non-notarised applications is now wrong. Users will now need to be instructed in how to bypass Gatekeeper as no Open option is offered any more.

    Some parts of the Handbook are duplicated. See eg pp37-38 and pp39-40 – the same except for the font change.

    Wiki urls are out of date (ie they have changed since the Handbook was started or chapters were written).

    It is “Raspberry Pi” not “RaspBerryPie”, “RaspBerry Pi” or “Raspberry PI”; it’s not a minicomputer it’s a microcomputer.

    There are numerous typos and grammar irregularities.

    The Handbook needs a very serious updating and professional proof reading.

    • The lack of communication? I don’t understand what you mean – we update as many as possible times..
      I will try to have a look at Mac Os X installation matter.
      The installation has been handled by my self in the first place: at that time Mac had no plans for the next level
      that was known to me. If you have the possibility to create a better and newer one, I would be happy to use yours.
      Otherwise I must find some one that has a new machine and the new operating system. About Carbon I can only say that I wrote what was available.
      I think you are right to have the installation rewritten, I will ask for help for that. Maybe you can give some?

      The duplication of chapters has been noticed but was already send. I have already updated that.
      I will remove the wiki addresses because they change constantly.
      At this moment there is one proofreader. We need more.
      We are still writing new chapters…So there will always be glitches. Not even if we have an army of
      proofreaders we can guarantee no errors.
      I am glad that you trouble of mentioning this. We will try to We will correct the errors.
      So please go on helping us.
      Thank you.

  • When the handbook is finally published, will it be available in hardcover/softcover and available for purchase in the U.S.A.?

    • The short answer is that the final version is build now.
      We are checking everything on errors and text errors. I think it will be available end of next week.

    • That version is ready, but under review. We plan to have it available by the weekend.
      It is of no use to send an older version. After this we will be ready and make it available.
      The number of pages is about 950.

  • Congratulations on finally getting to print. Huge effort on you and your colleagues part. Too many people think writing a manual/reference is a simple task 🙂 — they have no idea!
    I did think when I ordered the book, note singular, that your suggested publication date, 18 months ago, was a bit unrealistic considering the , then, empty spaces you had in the PDF. But these books, note plural, will be a very important part of the Lazarus story and should further interest people in trying it.

    Looking forward to getting my printed copy of the Handbook. While the PDF has been a very useful reference there’s nothing like a BOOK ! Even in today’s online fetish with book browsers , I like to margin note in my reference books, can’t do that easily in a PDF.

    • +1

      Recently I became interested in Lazarus to write multi-platform desktop application and after evaluating so many languages – both in static & dynamic camp, I’ve settled on FPC/Lazarus.

      Despite of having Object Pascal Handbook book in print, still I’m glad to support your efforts and will order my printed copy since I like holding real book in my hands hoping to serve me well for years to come. 🙂

  • Very pleased to read that the book is ready to be published. I have downloaded the PDF version and it looks good. Thank you to all for your hard work.

    There is one very minor formatting error on page 20 of the PDF book where the image of ‘The First Start of the IDE’ has merged with the page number.

    I’m sorry to report there is an ‘Arrrgh no’ moment on page 14 where the reference to the ‘Starting the IDE ‘ directs the reader to page 12 when of course it is chapter 1.4/10 page 20.

  • I want just to congratulate all of you here and all the lazarus team because with your hard work you keep PASCAL alive!!! Pascal receives today unfortunately laugh and bad comments from others that support the newest programming languages and they think that pascal is obsolete (they think that Free Pascal is the same as DOS turbo pascal). So thank you all that you show to all the people that pascal is still kicking and it’s alive and strong to build any program you want like the most new programming languages, it has a good community and people to support pascal. Please continue with the same love you have now the Lazarus IDE and the Free Pascal, never stop! Sincerely THANK YOU !!!!!!!!!!! And I think that many many people have the same feelings like me. KEEP UP THE GREAT WORK. THANK YOU ALL FOR YOUR HARD WORK!!!!!! PASCAL FOR EVER !!!!!!!!!!!!!!!!!!!!!!!!
