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…

As a Delphi/FPC/Lazarus veteran (10+ years), comparing one of the quickest compilers with Qt/Boost C++ development cycle looks like a joke. Much faster edit-compile cycle which scales without issues up 1e6+ LOC (yes, modules/incremental compilation done right right from the start)

The Python bindings to Qt don't require compilation. QML is an interpreted gui declaration, and Qt Quick allows programming behavior in Javascript.

> [x] Readable, somewhat python-like syntax I have a rather different opinion on OP that it has a needlessly verbose syntax. Pythonic it is definitely not. Even C# (which is another creation of Anders Hejlsberg, after MS poached him from Borland) has a better, readable and concise syntax. I used to be a Delphi evangelist in it's glory days. Now I bristle when I read Pascal source code, there's so much unnecessary vis…

My feeling as well. In my heart I am really happy that Lazarus (and Harbour, the Clipper-compatible compiler) exist, but being rational the days of desktop applications are over. Python is being run on microcontrollers these days; I actually wrestle with the non-adoption of Python (or Ruby, or Javascript, or Tcl) as 1st-class citizen language for desktop and mobile; it does not make sense for me. Certainly writing de…

> Python is being run on microcontrollers these days;

So does Pascal and its descendent Oberon, including FPGAs.

Natively compiled to machine code, safe, without any help of C.

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…

For those lacking CS background, reference counting is an GC algorithm.

The 5th chapter from "The Garbage Collection Handbook", http://gchandbook.org/, one of the most renowned books in the field, there are of course other equally renowned sources I can refer to.

WPF/XAML can give you amazing results but I'm nowhere near as productive with it as I was with VB6.

I would venture that WinForms is actually more RAD'ish than WPF. A lot of that productivity came from the drag-and-drop form editing. And what made it possible (and easy) was complete disregard for any kind of advanced dynamic layouts. Delphi's VCL, .NET's WinForms and the nameless VB6 UI toolkit are all designed around the notion of widgets manually placed on a 2D grid, and the most that you can get in terms of dyna…

While true, WPF development when coupled with Blend design can be very expressive.

The main hurdle is getting how templates, styles, triggers and code interact together.

If one happens to work in enterprise projects, it is quite easy to get WPF component libraries.

You are not comparing apples to apples.

Try finding any native code static typing compiler with RAD on board featuring quick compilation within 2x C++ resulting binary speed.

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 like your comment. It highlights what misses from so many discussion about languages/tools down here. Being expressive, powerful, compiled, interpreted doesn't matter much if long term stability, reliability, backward compatibility are not a top goal for the devs.

PyQt is nasty GPLv3 or commercial license only. (And no, PySide is not an option: their last stable release is years old and for Qt 4.)

mORMot framework is also a nice example for modern Pascal... https://synopse.info/fossil/wiki?name=SQLite3+Framework It has DDD, SOA, MVC, ORM (even for NoSql), REST, caching, logging and security features and works with Lazarus.

Looks great - have added to my research list on FPK. Thanks.

mORMot is very full-featured and powerful! I'd suggest to start with its rich set of samples (https://github.com/synopse/mORMot/tree/master/SQLite3/Sample...) and this blog: https://tamingthemormot.wordpress.com/
