Earlier quoted context omitted.

Lazarus is Object Orientated. Delphi definitely offers garbage collection in newer versions, not sure about Lazarus.

No. Delphi offers reference counting , but only on interface variables. It's a huge difference really, because if your last interface variable that points to an object goes out of scope, the object is freed from memory. Even if you have raw class pointers to it. Example: IMyInterface = interface procedure Foo; end; TMyClass = class(TInterfacedObject, IMyInterface) procedure Foo; end; procedure TMyClass.Foo; begin Wri…

One of the things I'm excited about, is using FPC/Lazarus as GUI for computationally heavy Go code (Now with the recent efforts to use Go for datascience ... see http://gopherdata.io ), now since Go supports shared object (.so/.dll) files. I collected my (very early) research on it in this thread: https://forum.lazarus.freepascal.org/index.php?topic=24948.0 ... where some users report they tried it already. Seems to…

I've made the mistake to write a complex project in Free Pascal. As far as I can tell pretty much every release of Lazarus is breaking something. And surprisingly often those breaks are major (like e.g. broken multi-threading, broken-strings, ...). For me the whole thing looks more like a playground for hobbyists and is not really useful for anything productive. There's not much continuity in the language. And for th…

I work with a multi-mloc application in fpc. We have migrated the code over many compiler versions with hardly any issues at all. With every update they post a list of things breaks compatibility, and if you are affected, the refactoring tools are almost always enough. We had two tries at a full recompile migrating from 2.6.something to 3.0.2, and passed all tests within 13 hours of starting the process. (some of the…

I mentioned Lazarus in other threads a few days ago (since my kids are playing around with it) and it's great to see it as a top-level post. Some random thoughts: - It's somewhat amusing to realize that in 2017 this is pretty much the easiest way to do a desktop app (besides RealBasic/Xojo which I've yet to try - was put off by their mandatory registration) - I wish we had RAD environments like this for more language…

I've not used Lazarus or Delphi, so I can't really compare properly. Perhaps I'm missing something. But: > if anyone knows of any similar environments (besides QtCreator, etc.) Why "besides QtCreator, etc"? It sounds to me almost like "do you know any X besides all of the popular X". Is there any particular reason you discount QtCreator? Does it not work for your purposes? Or is it just a case of you already know abo…

While we're at it, for those times when you're hacking on console apps, FreePascal also has a very nice text-mode (TUI) IDE that is basically a Turbo/Borland Pascal 7.0 IDE clone - but cross-platform. To do that, they had to port Turbo Vision (or rather its open source fork Free Vision). It's still a great TUI library... it's a shame it's Pascal-specific. Would be interesting to have an implementation of it for, say,…

The Turbo Vision IDE was actually introduced with version 6.0 as an example what the framework was capable of. It was later available in C++ as well, and there is a port available. http://tvision.sourceforge.net/
