[Lazarus] Delphi wxWidget plugin for Lazarus
Hi, Someone had made an interesting project. You may see the screencast here: https://forums.codegear.com/thread.jspa?threadID=14612tstart=0 Nice work! It's good for both sides, Delphi and Lazarus. But, I'm personally not interested since it would double my work, one with it, another with Lazarus. Lazarus alone is more than enough to me, . What I don't understand is the responses to this project in Delphi forum, as you may read here: https://forums.codegear.com/thread.jspa?threadID=14612tstart=0 Everyone seemed to be surprise and happy. As you already knew, Delphi people are quite offensive to FPC/Lazarus with many arguments which are mostly wrong and non-sense. But, if there's a project that *indirectly* uses FPC/Lazarus through Delphi, as this one and CrossFPC, they could accept it. Can someone explain this phenomena? :D -- -Bee- has Bee.ography at: http://beeography.wordpress.com ___ Lazarus mailing list Lazarus@lazarus.freepascal.org http://www.lazarus.freepascal.org/mailman/listinfo/lazarus

Do they have to create them in C++ (because that is what wxWidgets is written in) and then create Object Pascal bindings for those components. Double work!!

Re: [Lazarus] Delphi wxWidget plugin for Lazarus
Well, being a wierd Delphi guy, I hope I provided at least some rationale for the desire to see some kind of CrossFPC utility in my previous response. I miss my addins in Lazarus. Call me lazy, I don't care. I'll use any tool that means I write one less line of code or helps me write it faster. I'm more productive in Delphi, simple as that. But I do all my regular computing in OS X, and working on learning how to develop in it as well, so Lazarus is of very keen interest to me. Downloaded QT 4.5 last night and will follow the Lazarus OS X QT version much more closely now. I'd offer to help, but I'm potentially the worst C++ developer in the history of mankind... I agree with the second part per my email on the same topic. Unless they've done way more than I expect a complex app will feel handcuffed quickly. -Ron On Mar 31, 2009, at 12:02 AM, Graeme Geldenhuys wrote: On Tue, Mar 31, 2009 at 7:59 AM, Bee bee.ogra...@gmail.com wrote: Everyone seemed to be surprise and happy.

Call me lazy, I don't care. I'll use any tool that means I write one less line of code or helps me write it faster. I'm just like that! Hence the reason I ported and modified my Lazarus to suite my needs. I have a lot of customized keyboard shortcuts and a ton of code templates that get triggered with just a few keys. It took a while to get to this point, but I can honestly say I am now more productive in Lazarus than in Delphi. But the last Delphi I used was v7, so I can't comment on any Delphi IDE after v7.

Re: [Lazarus] Delphi wxWidget plugin for Lazarus
I don't see anything in the video that prevented you from making edits in Lazarus. He copies files back and forth for some reason, not sure what's up with that. I don't have to do that because VMWare Fusion allows for pretty seamless file sharing. As for CodeGear benefitting from embracing FPC, I haven't bought the argument. FPC and Lazarus would make a Windows only Delphi completely superfluous if they had the same third party component support that Delphi does. It would suffer the same fate as most Java IDE vendors as the open source ones got feature parity. Not interested in starting a debate on it, but I only see them becoming irrelevant by embracing FPC. If they want to survive, they need to make themselves a more compelling product than FPC and Lazarus are. They were on the right path with Kylix and completely dropped the ball. Then they dropped it with a costly, misguided .NET strategy. They're fighting for existence my friend and FPC/Lazarus only highlight their past failures and future challenges IMHO. -Ron On Mar 31, 2009, at 12:56 AM, Graeme Geldenhuys wrote: On Tue, Mar 31, 2009 at 8:58 AM, Ron Grove ron.gr...@me.com wrote: Having posted on that thread already, I'm not sure I understand your comment.

From what I could see in the video, he had to export the Delphi project to a Lazarus project - which ended up in a separate directory. I'm not sure if Delphi and Lazarus can share the same wxWidget based project (the point I was trying to make). Without actually trying it myself, I have no real clue what is possible and what isn't. As for CodeGear benefitting from embracing FPC, I haven't bought the argument. FPC and Lazarus would make a Windows only Delphi completely As far as I see it, CodeGear is competing in the Developement Environment market. To me, that is the IDE and VCL framework - not so much the compiler. So by them embracing the Free Pascal compiler, they already get a x-platform compiler (more than just Windows+Linux kylix compiler). Now they simply need to tune the compiler for new language features (D2009 language features etc) and build there VCL to be truely x-platform like LCL does. It's a three step process (to simplify things a lot. 1) Use the FPC compiler and make the existing Delphi IDE work with it. So CodeGear still gives Delphi developers all the IDE benefits and plugins like ModelMaker support, UML designing etc which Lazarus IDE doesn't have. 2) Now they can start making VCL x-platform - similar to what LCL does. 3) Release a new x-platform IDE based on the new x-platform VCL. But yeah, this is all a pipe dream. CodeGear is fighting to stay alive in a very competitive market - especially seeing that they limiting themselves to targeting only the Windows market and trying to compete with Microsoft and their tools.

Besides this, I suppose gdb executable is nice beast as well. It is an acceptable price. I wish designing webs and writing javascript for cross-browser solution were as cheap.

It also provides several helper methods to control with fine granularity
what messages to send. Some of then can be seen at
That's what we do in tiOPF as well. We have various 'log severities'
defined. At compile time or runtime (via Visual Logger window) you can
change log severities to see more or less information come through.
In Multilog, additionally to the log severity that's another variable:
the classes. The class is user defined up to 32 (in fact each class is
defined by a byte value). Each message is attached to one or more
classes. You can control what will send by ActiveClasses and DefaultClasses.
Say you have two messages.
Logger.Send('XXX');
Logger.Send([1], 'YYY');
If you set ActiveClasses to [1,2] and DefaultClasses to [0] only 'YYY'
is sent
If you set ActiveClasses to [1,2] and DefaultClasses to [1] 'XXX' and
'YYY' is sent
If you set ActiveClasses to [0,2] and DefaultClasses to [0] only 'XXX'
is sent
This is useful in events where you want to avoid messages triggered by
system events.
As an example, you want to know what happens to in paint routines when
you do some action in a control.
Set the log messages with a 'paint' class inside that routines.
Around the action routine do
ActiveClasses := [paint]
do some action
ActiveClasses := []
You can also play with the DefaultClasses.
This will prevent to log when the paint routine is called by the system
(focus change etc)
I have planned to add another layer to filter that will allow to filter
by thread, by type of message and also buffer in memory before sending
to the channel.
As example, it's possible to restrict to send only the messages that are
called below a method/function call stack.
Can you explain this a bit more... Including the call stack.
Currently my major obsticle in event programming is debugging the call
stack. I often do the following as a quick fix...
When EnterMethod/ExitMethod is used, multilog keeps a track of the
callstack. You can use CalledBy method to know if you are inside that
stack. Also the text file and the messages tree are built using that
info, so you can see the stack structure.
Also there's SendCallStack method that shows the fpc provided callstack.
MaxStackCount controls the size of the stack
There's room to improvements: automatically detect if you are inside a
method in the stack without the need to call Enter/ExitMethod, hook
Lazarus IDE/GDB to automatically insert the log calls without need to
change the source file.
procedure TMyform.SomeCall;
begin
Log(' TMyForm.SomeCall');
{ some code here}
Log(' TMyForm.SomeCall');
end;
I have improved on this slightly by using Interfaces. Create a
interface variable that on creations writes the ...' line and when
the variable goes out of scope and gets destroyed, writes the ' ...'
line automatically.
eg:
procedure TMyform.SomeCall;
var
logger: ILogger;
begin
logger := gLog.GetLogger('TMyForm.SomeCall');
{ some code here}
end;
But as you can see, it's not much of an improvement, because I now
need a local variable. :-(
A constant view of the callstack (say the last 20 calls) would be
pretty awesome. Anybody know if this is possible with GDB or MultiLog
etc?
See above.
