[Lazarus] List the procedures of a object.
Is there any how to list the procedures of a object? Att. Everton Vieira. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] List the procedures of a object.
I need to execute an procedure of an object if his exists, i'm doing some
tests and get into this, but this is generating an SIGSEV:
unit Unit1;
{$mode objfpc}{$H+}
interface
uses
Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls;
type
{ TTeste }
TTeste = class
procedure Proc;
end;
type
{ TForm1 }
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ private declarations }
public
{ public declarations }
end;
var
Form1: TForm1;
type
TProc = procedure of object;
implementation
procedure DoProc(Sender: TObject);
var
Proc: TProc;
begin
Proc := TProc(Sender.MethodAddress('Proc')^);
Proc;
end;
{ TTeste }
procedure TTeste.Proc;
begin
ShowMessage('oi');
end;
{$R *.lfm}
{ TForm1 }
procedure TForm1.Button1Click(Sender: TObject);
begin
DoProc(TTeste.Create);
end;
end.

Re: [Lazarus] List the procedures of a object.
Well, i manage to 'find' the procedure now is giving the SIGSEV when
is executed.
For the MethodAddress finds was need to be published.
unit Unit1;
{$mode objfpc}{$M+}

Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls;
type

TTeste = class

TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);

end;
var
Form1: TForm1;
type
TProc = procedure of object;
implementation
procedure DoProc(Sender: TObject);
var
Proc: TProc;
begin
Proc := TProc(Sender.MethodAddress('Proc')^);
Proc; -- Aqui gera o SIGSEV

Re: [Lazarus] List the procedures of a object.
I just did, the real case just saved me to do about 10.000 lines of code in
a very tedious job.
Became like this:
unit Unit1;
{$mode objfpc}{$M+}

uses
Classes, SysUtils, FileUtil, Forms, Controls, Graphics, Dialogs, StdCtrls;
type
{ TTeste }
TTeste = class
published
procedure Proc;
end;
type
{ TForm1 }
TForm1 = class(TForm)
Button1: TButton;
procedure Button1Click(Sender: TObject);
private
{ private declarations }
public
{ public declarations }
end;
var
Form1: TForm1;
type
TProc = procedure of object;
implementation
procedure DoProc(Sender: TObject);
var
M : TMethod;
P: TProc;
begin
M.Data := Pointer(Sender) ;
M.Code := Sender.MethodAddress('Proc') ;
P := TProc(M);
P;
end;
{ TTeste }
procedure TTeste.Proc;
begin
ShowMessage('oi');
end;
{$R *.lfm}
{ TForm1 }
procedure TForm1.Button1Click(Sender: TObject);
begin
DoProc(TTeste.Create);
end;
end.

I would.
Under command of some switch, of course, it surely would come in handy.
The rtti unit they made for it is of course totally convoluted, but the
idea
to be able to use introspection on all aspects of a class is definitely
useful
and would make RPC frameworks a breeze.
That's roughly my opinion too, after a short read-up during D2010 times.
Never enable it globally only for certain classes in frameworks that
benefit
from it. Haven't really used it yet though.
Well, I am using it - I'm exposing a JSON RPC through it.
The 'only for certain classes' is my point of view as well.
It would only be necessary for the classes that get exposed as data, and
the interfaces.

Re: [Lazarus] Project management
Em 01/03/2012, às 21:14, Juha Manninen escreveu: 2012/3/1 Everton Vieira tonvie...@gmail.com That`s true. To get the softer landing improving the doc (and i think the ways of it) would be enough. The project management is more about to lead the people to achieve common goals. I don`t know how you people from the core lives with so few contributors. The high goal of this thread is to improve that. Right... if you honestly wanted to improve the situation you could start contributing yourself. Until now we have seen only this abstract nonsense from you. Ok. I shall make no more comments on that. So, what does the management mean in practice? About management from the wikipedia: Project management is the discipline of planning, organizing, securing, and managing resources to achieve specific goals. Yes, I can read wikipedia. My question included the in practice part. The in practice is the system itself. It will depend on the politics adopted. This is not abstract. I`m not in the position to say on that. Marco? DoDi and others!!! Please don't hijack this thread for whining about documentation and docking and whatnot! You can do that in another thread if you must. Besides, you are supposed to improve the documents, not whine all the time like a baby. I don't know what is wrong with you. I plan, hopefully during Friday, to collect some valid points about how this project should be visible to outsiders, in a constructive way. It really doesn't help things when this thread is filled with irrelevant whining, pushing the signal/noise ratio close to zero. Is it a collective whining period now or what?

Re: [Lazarus] One thank.
I know the mailing list is the standard today, in many places not just here. But is unclear in his lack of formated data, maybe something like the bug tracker to discuss inprovements in which that info like the one you just sended about the TLabel and FocusControl could be added as notes. Would be much more clear. 2012/2/24 Juha Manninen juha.mannine...@gmail.com 2012/2/24 Everton Vieira tonvie...@gmail.com Is there any way, besides the unclear way of try to colect some coments in the mailing list about the acceptance of a specific improment? Of course, no one wants to throw away his work. Mailing list is a good place. If your idea is not good then it will be noticed early on and you don't need to make useless code. Good GUI design is especially difficult because it is always subjective, based on people's opinions, habits and preferences. About your idea of TLabel + the closest TWinControl, Taborder dialog may not be a good place for it. Anchor editor would be better but it is already full of stuff and it is meant for all controls. Your feature is only for TLabel. Maybe best would be a popup menu item in designer when right clicking a label.

You can perhaps make such front-end yourself as a contribution. :) It is not a trivial task because you must connect and update the actual Mantis bug tracker and mostly replicate its user interface. We can always starts small, makes more sense starts small. But, by now, i don't have a clue about how to start such front-end. It makes sense if the IDE can automatically collect information about an exception or other error, and about the environment like OS, FPC version, Lazarus version etc. Otherwise it does not make much sense to replicate it. BTW, this is not really an issue of project management but rather bug management.

With all that richness that has a project management: projects, teams, head members, status of it, code already done, code to be done, ideas about it, discussions on, notes from everyone, and so on. This was the best idea so far. I think there is open source project management programs available. However there is a big difference between professionally run SW projects and hobby open source projects: Professional projects in a company environment have a known number of developers who all will work a known period of time every day. If you can estimate how many man-hours a certain task will take then you can divide the tasks and estimate the whole project's development time. In a hobby project things are different. Nobody can promise exact number of hours to work on the project. Also, developers often do what they want based on personal preferences, not following some project manager's orders. This actually makes it fun to work in an open source project. Everton, did you consider these things in your suggestion? I think can be adapted. It would be mostly a ToDo list with task assignments and maybe time estimates. In fact the wiki already has such info although it is outdated. I am still thinking, do you need the project management data for getting a suitable task for yourself, or is it more like nice to know? I think would be better for everyone. It may also be an illusion from your side that contributing code to a big project becomes easy if only there was a project manager with a nice list of tasks. I think it would be easy with more info about it. No, you will have to browse and study the existing code for hours and hours before you start to understand it enough to make intelligent changes. I think it would be easy with more info about it. When you do it, other developers will be very helpful through the mailing list, I promise. Now you clearly have not even looked at the code. I`ve looked yes, some of it, not all for sure, but i do not see how this make any difference on this subject. Juha But, of course, if you don`t think is a good idea, then ok. Sure i`m not here to convince anybody of nothing. I`m only proposing ideas. Only that. Sure if this ideas don`t found resonance i would be the last to try to convince anybody.

Of course i dont really know what i want in this matter because doesn`t matter what i want. Is a project management, the concept of it is well know. How does fixing a bug or creating a new feature become easier if it is listed in a project management GUI? By start, the talked about it would be grouped. The info would be formatted. It doesn't, you still have to learn and edit the code. Certainly is suposed so. But is very different when theres some lines saying what that code is already doing. And some lines to saying what is missing, and what was already be talked about, by who, everything in a formatted way. And i think, in my humble way of view, that a GUI would facilitate and much more likely draw people to help. I filled my own and Mattias' data in the developers page. It is the organization chart that was requested: http://wiki.lazarus.freepascal.org/Developer_pages Do not see any i saying as a request. Then there is the roadmap page. It already contains tasks and people responsible for them. It is not up to date but can be updated: http://wiki.lazarus.freepascal.org/Roadmap Everton, could you please explain the problems you face in a more detailed way. Now this is all very abstract, like everything becomes easy with a project management system. That is, if you still want to learn and contribute. If you don't, it's OK, too. This is not about me. Why make this about me? This is about the group. From where i came from we have this saying: one andorinha bird doesn`t make summer. How can i tell this better. This meant that one can not make much, is the group that can make much. And of course i never said that: everything becomes easy with a project management system. Juha But i admit, maybe i`m wrong. That`s ok too. The project management in a open source environment, maybe is bad idea. Who never make some mistake? And of course is not in this struggling path that we can make a community that really cooperates. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] Class const of array of record.
I was trying to make this construction:

end;
function mTRec(Numero: Integer; Nome: String): TRec;
type
TTest = class
const Nomes: array[0..2] of TRec = (mTRec(1, 'everton'), mTRec(2,
'murilo'), mTRec(3, 'vieira'));

function mTRec(Numero: Integer; Nome: String): TRec;
begin
Result.Numero := Numero;
Result.Nome := Nome;
end;

i1: Integer;
begin
for i1 := 0 to Length(TTest.Nome) -1 do
ShowMessage(TTest.Nomes[i1].Nome);

In this constructions is that today is nice to use a function to create the

[Lazarus] Multiple views that are right.
We should always remember that are multiple views that are right. So, the better would be to find means that they could coexist. Like in this: http://bugs.freepascal.org/view.php?id=21263 I've said: But consider the idea to make some values property on dbcombobox. Luiz Americo said: TDBComboBox should keep as is, because not every one needs this feature. Then i replied: Isn`t better to put the values property in the dbcombobox and if is empty then is not used? This is an example, i'm not crazy about this feature, but in this example the new behavior doesn't affects the old one and can coexist peacefully with it and, of course, increase the functionality of the class. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

You do know shift-ctrl-space ?
Which opens a hint showing the possible parameter list(s). That also has the
advantage to work if there are overloaded versions.
I know. Thanks.
In 0.9.31 you can then insert the one you need, with the mouse (sorry no

Trim is bad example :) but if you wanted Ctrl+Shift+Alt+Space to expand, e.g.
AnsiReplaceString()
into
AnsiReplaceString('','','')
What would you put as 'empty' parameter for functions that have numeric
meaning,
and don't really tolerate 0 as input
As a code complementation suggestion theres no need to put 0 instead is better
only put the comma when the parameter is required.
(hypothetical: function Divide(A: integer; B: integer):Real;
if you expand Divide() to Divide(0,0) and forget to put some meaningful
constant into B
(or variable) you'll end up with executing div/0 and as such, an error)
As such such expansion IMO is futile.
This idea came when i had to type about ten times a function like this func('',
'', [], '', [] , []); wich time the parameters changed, of course i did ctrl+c
ctrl+v. This would be only a very subtle behavior. Like every one knows,
details are in the art of the elegancy.

Re: [Lazarus] Why the Java became so strong?
This discussion walked too much about the tech which i don`t think is the case.But JuhaManninen hadsaid sogoodly:"The fact is that FPC / Lazarus is an almost unknown niche language / environment. I am studying information technology and programming in a university of applied sciences and there nobody knows about FPC or Lazarus, not even the teachers. Everybody knows about C, C++, Java, Eclipse, .NET, C#, PHP, Python, sh scripts, Lisp, even Haskell, but not about FPC or Lazarus.If those people don't know, it means nobody knows.Comparing FPC / Lazarus directly with Java / Eclipse and saying they are equal is not a balanced comparison.

Re: [Lazarus] If TProcess.CommandLine is deprecated...
How about in the SetCommandLine, of the property CommandLine he does the split between exename and parameters. By this, the two options could be available. Of course, who puts a parameter with space and not set the will deal with some error, which is good to learn. About that, could be created some manner to offer hints and tips on code editor in how about to use de elements of the class. It's will be very good documentation and also very good IDE behavior.

Make sense. Thanks. But the previous idea of show the net development of the documentation with examples and tips of use it in the IDE is very good. The help of the delphi was always good, i remember the early days that i`ve successfully used. And the idea of keep multiple functionalities with different behaviors is also good, the problem in that is the rain of question that could came, and the solution of it is an good IDE help.

Yes, is some like it i`m already doing. But this mean to put a lot of DumpStacks in the code witch is not nice. How can the debugger know that a specific line is about to be executed.

btnAdd.Glyph is a TBitmap and therefore reads only bitmaps. But you

Try doing it like this:
