If my source code only contains tab( #09) characters, and not spaces, it results in a much smaller file size. Does that also translate to FPC being able to parse that source code faster (less characters to parse), and does that also translate to the SynEdit component working faster (again, less characters to process)? Some form of speed test to compare the difference should be interesting. :-) Regards, - Graeme - -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://opensoft.homeip.net:8080/fpgui/ -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Onderwerp: [Lazarus] object type: strange behaviour
Hi all,
I'm converting a project from Delphi to FreePascal. It is a mathematical
application that uses records with methods. Since this is not possible in FPC
I
am trying to convert this base type from record to object:
TPoint = object
public
X,Y,Z: Double;
class function Create(const Ax, Ay, Az: Double): TPoint;static;
class function Distance(const P1, P2: TPoint): Double;static;
end;
class function TPoint.Create(const Ax, Ay, Az: Double): TPoint;static;
begin
Result.X := Ax;
Result.Y := Ay;
Result.Z := Az;
end;
class function TPoint.Distance(const P1, P2: TPoint): Double;static;
var
aX: Double;
begin
aX := Sqr(P1.X - P2.X) + Sqr(P1.Y - P2.Y) + Sqr(P1.Z - P2.Z);
Result := Sqrt(aX);
end;
So far so good, this works (compiles and produces the desired result):
var
P1, P2: TPoint;
d: Double;
begin
P1 := TPoint.Create(0,1,1);
P2 := TPoint.Create(1,0,0);
d := TPoint.Distance(P1, P2);
WriteLn(d);
ReadLn;
end.
Now there is a class type that has a TPoint field:
TNode = class(TObject)
public
FCoord: TPoint; { coords }
constructor Create(const X, Y, Z: Double);
end;
And a constructor that sets this point:
constructor TNode.Create(const X, Y, Z: Double);
begin
FCoord.X := X;
FCoord.Y := Y;
FCoord.Z := Z;
end;
This works, however this doesn't:
constructor TNode.Create(const X, Y, Z: Double);
begin
FCoord := TPoint.Create(X,Y,Z);
end;
It fails with an error: Class isn't a parent class of the current class. If I
set TNode.FCoord outside the constructor there is no problem at all. Also,
when
I try to access other methods of TPoint this fails (see UpdateCoord in the
full
source below).
Any idea what causes this behaviour? I included the complete code below for
your reference.
Kind regards,
Birger Jansen

[Lazarus] LazBuild does not create the target output directory

Re: [Lazarus] object type: strange behaviour
TP Objects were implemented as Records with methods years ago - but it wasn't really true OO. There was no concept of a class - and objects were literally nothing BUT a record with methods, only the barest concepts of virtual, private and public methods were present, inherittence was... shoddy at best... It was a poor man's OO before OP gave us proper class-based objects. The whole records-with-methods thing to me sounds like a cheap way of using code that was lying around to add an entry to a featurelist that was technically already there ages ago - and useless.

[Lazarus] Dual installation of FPC
I have FPC-2.4.0 (fpc.cfg is in /etc) installed on my Ubuntu 10.04 system, and use exclusively Lazarus SVN which I continuously update and build from within the IDE without any issue. I tried to install FPC SVN: I checked out the FPC trunk to ~/Programs/fpc/fpc-svn mkdir ~/Programs/fpc/fpc-2.5.1 cd ~/Programs/fpc/fpc-svn make clean all install INSTALL_PREFIX=~/Programs/fpc/fpc-2.5.1 It created in ~/Programs/fpc/fpc-2.5.1 the following directories: bin: fpc and fpcmkcfg executables are here lib/fpc/2.5.1 (contains ide, msg, and units directories as well as ppc386 executable) share (contains doc directory) cd ~/Programs/fpc/fpc-2.5.1/bin fpcmkcfg fpc.cfg I added to the new fpc.cfg: -Fu~/Programs/fpc/fpc-2.5.1/lib/fpc/$fpcversion/units/$fpctarget -Fu~/Programs/fpc/fpc-2.5.1/lib/fpc/$fpcversion/units/$fpctarget/* -Fu~/Programs/fpc/fpc-2.5.1/lib/fpc/$fpcversion/units/$fpctarget/rtl At this stage, I did not use the new fpc.cfg, but edited instead the old fpc.cfg commenting out the old 3 -Fu lines and adding the new ones. In terminal: export PATH=~/Programs/fpc/fpc-2.5.1/lib/fpc/2.5.1:$PATH export PATH=~/Programs/fpc/fpc-2.5.1/bin:$PATH At this stage, fpc -v shows 2.5.1 I launched Lazarus from the terminal (so that the exported paths persist): Lazarus env options: Compiler path: ~/Programs/fpc/fpc-2.5.1/bin/fpc FPC source directory: ~/Programs/fpc/fpc-svn/ I rebuilt the IDE which complained about lnet package not compiling and asking if I should remove it and showed 2 buttons: Remove and Yes!! (this is a bug). I removed the package manually, and the IDE was built successfully showing 2.5.1 in the About box. The question remains how to handle the paths and fpc.cfg so that Lazarus can use both FPC versions on demand (by changing the compiler path and FPC source directory entries).

The most obvious location is missing. That is between 2 and 3, the indented code after begin. Usually the codetools-based autoindent takes care of it when you press Enter, but not always. To make the tab smarted it could ask for info from codetools about good indentation spots. Another improvement would be to inspect the surrounding code instead of just preceding code. For example if I want to align comments: s1 := MyFunc1(); // Comment at the column I want it to be. s2 := MyFunc2();| -- cursor Now the tab is smart, good. But if I have: s1 := MyFunc1();| -- cursor s2 := MyFunc2(); // Comment at the column I want it to be. The tab became stupid again.

[Lazarus] Release schedule and policy
Hi I would like to suggest again a new release policy. It would have timely releases, meaning a new release after a fixed time period, at a predefined date. Some projects have a 3 months cycle but a 6 months would be enough for Lazarus because of more limited resources. Every release would be basically cut out from trunk. It would be verified to compile and to work with some big test projects. Nothing else. Then it could be called release x rc1. After one week testing and maybe applying fixes from trunk, it would become the release x (without rc1). After that there would be maintenance releases in a timely fashion (or when needed). The important point is that emphasis would move from the release itself to its maintenance. The challenge is to find all needed fixes for the maintenance and to apply them. Basically all commits in trunk could be classified as feature or bug-fix. Bug-fixes should be applied also to maintenance branches. The division is not always clear. Who classifies them, the author of the commit or the branch maintainer? To support this process, any new big feature should stay in its own branch first and be merged to trunk some time after a release (not just before a release). I could help somehow in this process. I believe that lack of resources is a problem when implementing such a model. The current situation is frustrating to everybody. Lazarus is evolving and most users must use the development version because it is better than the release version. Some people explain bugs in release version which are fixed over half a year ago. It is frustrating also to Lazarus developers because the release can happen only when all bugs are fixed. That is not realistic as we all know.

The directory specified in the environment variable PPC_CONFIG_PATH, and if it is not set, it will look in the etc directory above the compiler directory.

I believe that lack of resources is a problem when implementing such a model. I guess: yes, you hit the nail on the head. To support this process, any new big feature should stay in its own branch first and be merged to trunk some time after a release (not just before a release). I am not sure this is a goof idea. 1) Who defines what is a major feature? 2) we do not want 20 or 30 different branches? 3) New features would take longer, since they were no longer tested. Of course, the end-user a forced tester would anyway no longer be there (since they could stick to releases), but at least other developers would still use all new features. Personally, I don't mind the occasionally issue with the IDE caused by somone elses new work. I do the same sometimes, and I am always glad to get feedback as soon as possible, as it makes it much easier to fix the issue. I believe, trunk should stay open for all work (extremely experimental work can and should go into branches, as has in the past). Then you would have one or 2 maintained branches: a) the fixes branch as currently b) the next release branch, which is based on fixes, but also gets features merged as soon as they are deemed stable. Some end-users may even want to stick with this. And those 2 branches, are what will take a lot of work. If someone is willing to do that work, then I guess that's all it takes. Every release would be basically cut out from trunk. It would be verified to compile and to work with some big test projects. Nothing else. Then it could be called release x rc1. After one week testing and maybe applying fixes from trunk, it would become the release x (without rc1). After that there would be maintenance releases in a timely fashion (or when needed). See above. There are also some existing test cases. They could even be used on the b branch from above, on every merge..., but again: maintenance resources. The important point is that emphasis would move from the release itself to its maintenance. The challenge is to find all needed fixes for the maintenance and to apply them. Basically all commits in trunk could be classified as feature or bug-fix. Bug-fixes should be applied also to maintenance branches. The division is not always clear. Who classifies them, the author of the commit or the branch maintainer? Well I think, the commiter can flag them with some sort of hint, the maintainer decides. Depending on how much work the maintainer wants to spent, I would suggest, that each fix, should stay one or two weeks in trunk, before being merged anywhere else. That way, if it breaks something else we may spot it before merging it. Or it first merges into b-next-release, and if no complaints are received, then into fixes my 2.5 cents Martin -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

No, my idea was that only a new feature which is guaranteed to be broken at the time of next release date, is kept in a branch until the release. Then it can be merged and tested by all trunk users. It will make it into the next release. For example if you start a new Enhanced Smart Tabs feature a month before a release, and it will surely mess everybody's code at that moment, then it should go to a branch. There would not be very many such branches. It would just be a compromise between the current situation when everybody must use the development version and suffer from its broken stuff, and the goal to make a perfect release when all bugs are fixed.

I had a different idea here (if I understood your text right). The next release would be based on trunk only. It means it would not be stable and well tested. Later it would have maintenance-patches and -releases and would become more stable. Having a certainly broken feature in a branch and excluding it from release tries to make the initial release more stable than the trunk currently is. The release maintenance branches would get only bug fixes, no new features. This is all about finding a good compromise. The current situation is not good.

if Dir'' then begin
