 Posted: Wed May 27, 2015 11:07 pm Post subject: What do you like about lazarus |
 |
|
I want to learn about lazarus, and object pascal in general.
So i want to hear everybody's reason to learn lazarus.
What do you like about lazarus or pascal?
Please dont mention about: how easy to build interface using lazarus.
I was thinking like that before.
But now i dont know anymore.
My IDE is just TotalCommander and SciTE, but i can build any interface i want, more easy than if i imagine to build interface with lazarus by text editor only.
Please dont misunderstand, im not using qt or wxwidget or gtk or anything that known beside just compiler.
So i cant look for that reason.
I look for anything else.

i like it because:
i know and understand it better
it allows inline 64 bit assembly
and as you stated, the interface design is a lot easier. I hate and actually refuse to design gui's in text editors

That is a terrible reason to learn something. You won't get far even if you decide to. Also you don't understand i guess that Lazarus is an IDE, you mean you want to learn delphi or pascal lol.
I don't like Lazarus, i tried to compile CE and holy shit, it is a terrible terrible IDE ever built. There is no backward compatibility, you need to actually have the same version that DB uses to compile CE or it would throw a thousand errors. I can compile my old code written in VS 2005 completely fine in the new VS 2013 without having to worry about versions. Actually, that is true for other IDEs i have used, they all support their older versions.
I haven't used it aside from that to know what i like or don't like about it, i tried to learn delphi and it is similar to c++ in some aspects that i see no reason to learn it, doesn't offer any benefits that c doesn't, the support for 64-bit inline assembly is enticing though.

I dont need to go far, because my basic is c and a bit cpp.
And i think it is good to be able to communicate with everbody.
And about lazarus, i too found something a bit odd.
But i think it is not a big problem, because in visual design, that problem will not seen.
I try to to look at lazarus example: hello.pp and helloform.pp.
And surprise that to build simple window and a button, it need about 50 line or ';'. This is something that disliked by many programmer like me who prefer text mode programming.
While in c/c++ language, it should be only about 12 line.
Ah yes, i am only using vc6 and tdmgcc right now, with no widely known interface library support like qt/wxwidgets, or gtk, or something else.

Majority of the users that have come and gone from this forum do not use Delphi / Lazarus. So your opinion there is kind of mute.
As for the UI example you looked at, and comparing C/C++ to it, that is because there are two separate things going on there. In the Lazarus instance, you are looking at a wrapped creation of a window and a control that lets you specifically set each property of those controls. Where as with the C/C++ versions most of the same things are bundled into the single API call. I wouldn't say it is too fair to compare two separate style things (one being a wrapper around an API, the other being straight API). Along with that you also are skipping over a lot of other details that are involved in the Lazarus example.
For example:
| Code: | | button1.OnClick := @button1click; |
Here you have a simple property to handle when the button is clicked. A function named button1click will be called. That is 1 line of code that is using the Lazarus UI wrappings. In straight C/C++ this is going to require you to have a window callback, along with handling the WM_COMMAND event, and within that event handling the specific command ID assigned to the button you created. Which is going to be a lot more lines of code then that simple 1 setting.
I'm not saying one or the other is better, it is clearly dependent on what you plan to do with the language.
I suggest that you, instead of picking a language with the attitude strictly of 'Dark Byte uses it, I should too', to actually picking a language because you are genuinely interested in learning it and making use of it.

Not sure if the ; was a complaint because most languages make use of semi-colons as line endings.

Not just because DB use it.
Many people use pascal-lazarus.
In my country, there are many user of pascal-lazarus.
I want to communicate with them too .... hehe

I typed wrong, sorry.
I mean 22.
More or less, like in this example:
| Code: | #include <stdio.h>
#include <windows.h>
#include <w.h>
struct {
wObj hwnd0;
wObj hwnd1;
} Form1;
BOOL Form1_hwnd1_OnClick(HWND hwnd, WPARAM wParam, LPARAM lParam) {
PostQuitMessage(0) ;
return TRUE;
}
int __stdcall WinMain(HINSTANCE hIns, HINSTANCE hPrevIns, LPSTR lpszArgument, int iShow) {
Form1.hwnd0.Open("wDefForm", 0, 0, 0, 100, 100) ;
Form1.hwnd0.SetText("Hellow World") ;
Form1.hwnd1.Open("wDefButton", Form1.hwnd0, 0, 0, 20, 20) ;
Form1.hwnd1.OnClickProc(Form1_hwnd1_OnClick) ;
while (GetMessage (&msg, NULL, 0, 0)) {
TranslateMessage (&msg) ;
DispatchMessage (&msg) ;
}
return msg.wParam ;
} |

in lcl/pascal that'd be:
| Code: |
program project1;
uses Interfaces, Forms, StdCtrls, Classes;
type TNoClass=class procedure fclick(sender: TObject); end;
procedure TNoclass.fclick(sender: TObject);
begin
Application.Terminate;
end;
var
f: TForm;
b: Tbutton;
begin
Application.Initialize;
f:=TForm.create(application);
f.Caption:='Hellow World';
f.BoundsRect:=rect(0,0,100,100);
b:=Tbutton.create(f);
b.BoundsRect:=rect(0,0,20,20);
b.OnClick:=@TNoclass(nil).fclick;
b.parent:=f;
f.show;
Application.Run;
end.
