    One of the best on its field!

    Lazarus is an excellent ide for the powerful modern language FreePascal (FPC). Pascal is both easy to write and hase good performance. Freepascal has through the years added the very useful generics, managed variable arrays, extended records, interfaces etc. With version 4 of the IDE, the developers have enabled a docked approach and made it stable. The editor syntax completion feature is really amazing and better than most of the stuff i have tried for Rust. (BTW: rust and pascal share so many features, but i personally think Pascal has a so much better syntax than Rust. But of course your mileage may vary). This is my fourth decade coding in Pascal and the language just keeps getting better without sacrificing simplicity. Keep up the amazing work!

    Very good program language! I made several program's with it! You can find Srt Editor here on Sourceforge and it was made with Lazarus.

    Lazarus is a fine project, but the lowest rated comment currently visible at the top is one that new users may take at face value and think that cross compiling is difficult. It is not: * If you are using 64 bit Lazarus on Win64 and want to generate (and debug) a 32 bit executable then install the associated lazarus-x.x-fpc-y.y.y-cross-i386-win32-win64.exe from the files section. Similarly you could install 32 bit Lazarus on Win64 and cross compile a 64 bit executable. * If you want to cross compile from Windows to Linux or vice versa, or to a different CPU architecture, then I suggest you use the excellent FpcUpdeluxe available on GitHub. FpcUpDeluxe will usually install the required binary tools as well.
