Now in most case data modules expose interfaces that the GUI parts of the app call to get data. My problem now is the other way round, where the Data Module needs to connect with the GUI first, in that whether or not the GUI is running, the Data Module can make a call and send the data to it if it exists, but without having to compile in any GUI dependencies. In effect I need the GUI to register something the Data Module or console app can use to notify the GUI in some way because I need to move to a model in which the GUI and Data Module/Console Program are running as separate apps.

The data modules need to send the output to the GUI and I am now making the linking of the data modules with GUI conditional with preprocessor directives. I can't say I am familiar with the LCL structure, lazbuild etc, so I say let NoGUI remain to ease the reorganization of existing GUI apps. My main concern now is how the GUI part of an app can expose an interface to data modules that do not require the data module to link with GUI libraries. The first thing that comes to mind is to use internet sockets for the interprocess communication, but it feels rather awkward as the presence of the necessary ports cannot be guaranteed on any system.

It is clear that a number of them are developed for the programmers own needs. Even if they are capable enough to serve your needs, those features may not be well documented. They turn out to be 'useful enough' for many others and are included in the Lazarus package. If sqldb cannot serve your needs, or that aspect is not well documented or lacks examples, try zeoslib. I have used zeoslib, which has been around for a long time, and I suspect it will be capable of what you want. PS.

Sometimes you need to do a whole lot of processing, and if you have to drag all the data down a slow WAN link for processing, the app will fail miserably. When you need to poll the database every second for some events, it is much easier to do the processing server side and return the results. There is also the need to keep critical logic server side for security reasons. Have you ever viewed your apps strings at runtime to see how much of the programs SQL logic is exposed?

There is nothing better than going to the Repository page in Redmine, clicking on a file, selecting 2 commits and seeing the changes between them, and for a lone developer it is very useful and important especially on long term projects. I have used subversion in the past, not much though, but I have taken to git much better. I think the main problem here how much time it takes a newcomer to ease himself into using a new set of tools, and it applies as much to a person moving to git to subversion (God forbid!!

Are there some code examples which use this approach, especially the package based one? Will it also reduce the size of the debugging exe or speed up its creation? Sometimes I see only one file compiled, then it goes to the linking phase, but it doesn't seem to reduce the exe size or the speed of its creation. > ___ > Lazarus mailing list > Lazarus@lists.lazarus.freepascal.org > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] I desperately need some ideas of reducing edit, compile, debug cycle
One thing that has always gottem to me when using Delphi and now Lazarus is the tedious edit, compile, debug cycle. It has been growing worse of late that now I am beginning to dread the whole process any time I have to make some changes, especially when they are just minor GUI changes. I have to wait for what is now approaching 60Mb of debugging enabled exes to be generated every time before debugging can start and I'm afraid I am beginning to show signs of an ADD. I tend to approach development with what I can do in the mean time whilst stuff is cooking. The problem is the is duration too long to be staring at the screen, and too short to give something else your attention before coming back to it. I guess for compiled languages ObjectPascal isn't bad, I believe it is even worse for C++ programmers. I may have to get a hex core CPU with 24Gb of RAM, and the fastest SSDs to make the process tolerable. Some hosting providers are doing them for circa €100 a month. Quite simply I am thinking of a way to create the application in parts, so that the parts containing the new functionality can be developed separately as standalone programs, perhaps even console programs. This raises the question of how procedure parameters and results can be passed, and these are the options that have initially come to mind. 1. Find a way to automatically translate simple variables, record structures, or objects into text and pass them via the command line or pipes. Perhaps JSON, XML or simple name-value pairs can be used here. Designing the parameters as TPersistent objects that are streamed into text form may be a better option here. 2. Rather than using the command line, make them network services and pass the parameters that way, or may make them RESTful/XML-RPC with all the new webby stuff( I am getting into some of that stuff now) 3. Design them as DLLs initially - I suspect that will bring along a different set of problems. Once they are well tested I can incorporate them into the main executables.

[Lazarus] Should using frames result in duplicate name errors?
I am trying to use frames to create the same element repeatedly on a form, but when I copy them in the IDE or create them and set their parents at runtime, I get duplicate name errors. Isn't Lazarus supposed to give them different names. embFrame1 := TEmbBoothFrame.Create(self); embFrame1.Parent := Panel10; embFrame1.lblDestination.Caption := 'X'; embFrame2 := TEmbBoothFrame.Create(self); embFrame2.Parent := Panel11; embFrame2.lblDestination.Caption := 'Y'; The above code generates the error: Duplicate name: A component named EmbBoothFrame already exists. Is it possible to get it to set a new name at creation time? On closer look it looks like the use of self means it is being attached to the form, would Application work much better ie embFrame1 := TEmbBoothFrame.Create(Application)? I tested with Application and it works On the other hand it appears that when I add the frames from the IDE, the duplicate name issue exists. Is it possible to pass the desired name to the Create function in this case? Are frames the right thing for this or is it templates instead? But I can't find templates in the IDE menu or the palette (Lazarus 0.9.28.3). -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] How do you create some kind of type definition based on adding a set if identical functions to different objects with different ancestors?
I don't know whether interfaces are what I am looking for here. I am creating an object called TStateInfoSource which needs to display its state using different objects, mainly a TForm, a TFrame, some future TComponent based visual object and a web interface as yet undecided. eg, both the TForm, the TFrame and web object are to implement a function called DisplayState in their own way. Is there some way to create some kind of type definition called a TImplementsDisplayState so that TStateInfoSource can call the DisplayState function of TImplementsDisplayState object it is associated with at runtime? In effect the TImplementsDisplayState facility is added or associated with existing objects, rather then having TForm, TFrame etc as its sub properties or components. In this way the display code is implemented directly by the form or frame, rather than having the TImplementsDisplayState object manipulate the form or frame's elements directly. In effect is it possible to put a group of unrelated objects into the same type definition by adding to them a set of identically defined functions? -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Runtime source code can also be formatted properly or even have an order of generation so stuff don't get move around much. It can even be generated in separate files, or as Graeme said in some private section of the file. Eg. when you move components around sometimes for the sake of accessing other components properties to change them, it creates a lot of noise in the diffs, as positions in most cases are irrelevant to a lot of components. Setting properties in code is fine, and some design IDE component can be used to generate the source code to initialize them at runtime. To be honest it is something I noticed some time ago, but never realized how hard it could hit if you made some error or forgot about something. Perhaps Graeme will permit the inclusion of that kind of facility into Lazarus in some future version, and component designers can include it in their component design. -- > ___ > Lazarus mailing list > Lazarus@lists.lazarus.freepascal.org > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

Does TObject have all the capabilities of TComponent apart from things like streaming and being used from the IDE component palette? I want to create an object which has all the capabilities like getting and setting properties, and I want to know whether I need to inherit from TObject or from something further down the hierarchy. Another aspect is ownership. Does ownership require objects to be derived from TComponent? Is a TPersistent adequate if manipulating the object from the IDE isn't needed?

I don't even know whether I have a place in the FreePascal community that entitles me to make such criticisms, and in a way I may be guilty of what I am accusing you of. I don't know much about the private and working lives of the developers of FPC/Lazarus, and how much time they can afford to give the project, unless perhaps it impacts upon their own paid work, and probably neither do you, so I wouldn't criticize them in anyway. I am more of a taker than a giver here, as are a lot of FPC/Lazarus users. I also don't know the issues which go into what they prioritize so I wouldn't criticize them on that. It is clear from your output you are a talented and committed contributor to the FPC/Lazarus community and perhaps you feel that others do not have the commitment nor the vision that you do, but I don't think this is the way to express yourself. There shouldn't be any "you" or "you guys" in Lazarus or any other volunteer project, nor should they be addressed in a mocking manner - there should only be "we" or "us". I posted this article - Observations on FreePascal and Lazarus Development<http://devblog.brahmancreations.com/content/observations-on-freepascal-and-lazarus-development>on my blog a few days ago, but because I haven't started any concrete work on it, nor do I know when I can make time for it in the near future, I decided not to publicise it, unlike Build Scripts<http://devblog.brahmancreations.com/content/build-scripts-for-installing-freepascal-and-lazarus-from-source>. If others come across it because they like the blog that would be good. A similar issue came up in this thread on the forums - http://www.lazarus.freepascal.org/index.php/topic,10693.0.html - where I kind of inserted by observations in a sidewise manner. Perhaps this drupal.org <http://drupal.org/node/897616> link may be of interest to you, but as a seasoned open source developer you must be familiar with the issues it addresses. As an aside, I know the debugger issue you raised and it can be easily sidestepped by creating some simple variables and assigning the contents of the expressions you want so they can show in the debugger - a few judicious IFDEFs are an easy workaround. Many times I know the issue will hit and I am often too lazy to do it upfront (hint, hint), even though I know it will save me sometime in the edit,compile,debug cycle. Much easier than charged comments. You should also realize that Lazarus does not have a great deal of commercial support as a lot of Delphi using companies are quite happy with it, even Delphi 7, and are not ready or interested to focus on the Linux space, unlike Ruby, Python, Scala and the other new fangled kids on the block.

I spent a some hours trying to use the original fcl-web in 09.28 rather than the new one in svn, and I couldn't get a database entry form working quickly enough. I turned to FreeSpider at http://motaz.freevar.com/freespider.htm, which was developed on the 0.9.26 foundation and even managed to switch the database over to zeoslib in a couple hours. Yet I suspect that fcl-web, even the original in 0.9.28 has more depth than FreeSpider, and produces smaller executables. It only lacks the documentation and examples to ease people into it. A demo just like the one with FreeSpider, one more database oriented, even the basic version in 0.9.28, it would go a long way to its take up.

Compiling from svn may fail. How does the new user know which revision they are using? If some bugs creep into the packages and the new user has to recompile where will the knowledge of what revisions are okay come from? Compiling directly from svn without knowing which revisions are safe may only cause more confusion as errors will be hard to track down. Unless the Lazarus community keeps track of stable builds, and getting the installer to download only those, this approach will only cause problems for new users. You only have to read the forums and mailing list to see how a lot of users are afraid to upgrade from source because the methods described in the wikis and faqs overwrite their existing installations. I designed the script is with that issue in mind. The user can symlink to a 'safe' build if it proves 'stable' long enough for their purposes. > Marcos Douglas > > -- > ___ > Lazarus mailing list > Lazarus@lists.lazarus.freepascal.org > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

When I check the nginx, this is what I see. 1. At boot time, an fcgi launcher is loaded as part of the /etc/init.d sequence 2. This fcgi launcher is linked with an ip:port combination or unix socket, and specifies a program which launches the web developers cgi script. 3.

I'd say use a batch file or some other script, and create a GUI interface to it. This GUI business is rather over done. You could try Pascal Script, thus have your Pascal cat and eat as well With my bash script all you simply specify the variables at the top and run it. Building a different revision is a simple matter of changing $FPC_REVISION or $LAZARUS_REVISION and Bob's your uncle. None of the existing stuff gets touched. The only shortcoming as I see it now is I have omitted to restore the $SYSTEM_FPC_COMPILER's original fpc.cfg to the home directory as .fpc.cfg, when I rebuild the compiler with its self. . > Regards, > Kjow > > -- > ___ > Lazarus mailing list > Lazarus@lists.lazarus.freepascal.org > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

There is no real reason for that, I have created a visible symlink to it
now. It is just that Linux creates too many visible folders in $HOME and I
wanted it to be invisible. I realized the folly soon after and created the
symlink rather than rename it and break a whole lot of existing stuff.

A lot of howtos do not focus on structure, they operate on a very low level of abstraction. Howtos should be like functions or procedures. You state what the parameters or variables to the function are. The reader takes a look at the parameters to the function, and learns about the structure of that domain from the parameter names and the comments attached to them. A lot of the time those comments are not even necessary. The better parts of Lazarus and FPC are in subversion, and as the revisions constantly change it is important to label the builds properly and label the directories and settings locations properly which is why I created that script. It may appear to be overkill but I'd rather know where I am and what I am using at all times. Symlinks can be used to point the system's ie the one in /usr/lib,/usr/bin etc. In this case you still know what builds are being used by examining the symlinks. Building some of the revisions often fails which is why labelling them is so important. The reasons why Lazarus and FPC compilations fail, which is mostly due to incorrect fpc.cfg, lazarus executable, fpc/ppc386 executables, /fpcsrc directories, the settings etc are there reason why that script is the way it is. I spent hours unravelling them, and anyone who familiar with those issues will understand why I strove to get them right that way. I am also developing for Ubuntu 8.04, which is not up to date like later versions. I will probably comment it further to help newcomers understand its structure, and I would like those more familiar with the Lazarus/FPC compilation process to correct any errors or misunderstandings on my part. With respect to Win32 the buildfaq document has a sample batch file at 2.4.4 which illustrates my point, but does not go far enough. As an aside I think the noise level in howtos in the blogosphere and the internet in general is simply too high, and attention get's caught in trivia and boilerplate stuff. > Marcos Douglas > > -- > ___ > Lazarus mailing list > Lazarus@lists.lazarus.freepascal.org > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

You only have to look out for the Windows gotchas. I will have tackle in the near future, but I wouldn't want to keep you wating. Check Marco van de Voort's buildfaq<http://www.stack.nl/%7Emarcov/buildfaq.pdf>, Chapter 2.4. The wiki also has tips on compiling at http://wiki.lazarus.freepascal.org/Installing_Lazarus#Compiling.2Finstalling_FPC_and_Lazarus_from_Sources_of_SVN_.28Win32.29 It is the type of article I don't like because you can learn a lot more from a good well commented script with sensibly named variables (insert smug emoticon here) ;). There is some good information here too - Lazarus Support FAQ<http://www.lazarussupport.com/lazarus/Lazarus?section2=FAQ#How_do_I_compile_lazarus.3F> I think it can be translated straight as is to Windows, with some minor adjustment of path names. The important thing is to specify the actual location of the fpc compiler, rather than use the system installed on especially if you are going beyond the basic fpc 2.2.4/ lazarus 0.9.28 combo. Once you get an fpc 2.4.0 working, you can go on to an fpc 2.5.1 and things will be match easier then. Another important point is to make sure you have the fpc.cfg right for the compiler, which is why I always regenerate it for a compiler just before 'making' with it.

For instance I have just posted a blog article on FPC/Lazarus compilaton at http://devblog.brahmancreations.com/content/build-scripts-for-installing-freepascal-and-lazarus-from-source, and what I want to do is to have the build_name variable as available to the IDE. e.g if a lazarus build is named lazarus_0920_27001, I would like to use a macro based on the package name as well as the lazarus build name, so the compiler knows that units for zeoslib for instance go to directory /components/lazarus_0920_27001/zeoslib. Even if the package sources must be modified that should be a minor problem. Surely something like that must be possible. I think it would also solve the problem of backporting packages made for fpc 2.5.1/lazarus 0.9.29 to the 0.9.28 and even the 0.9.26 series as it is extremely unlikely that they depend on language features only present in fpc 2.5.1. Delphi developers are still producing code compatible with Delphi 7. Delphi 7 still appears to be the reference platform for Delphi development. > Mattias > > > -- > ___ > Lazarus mailing list > Lazarus@lists.lazarus.freepascal.org > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] How would you organize build directories for different versions?
If you are using different Lazarus versions but with same components and packages, how would you organize separate build directories for the different versions, but same source location. eg. say I am using fpc 2.2.4/ lazarus 0.9.28, fpc 2.4.0 / lazarus 0.9.29 and fpc 2.5.1/ lazarus 0.9.29 All though the package source files would be in one place (with necessary ifdefs for compiler and lazarus versions) I would like the units to go into say lazarus_0928_224/components/package_name_dir, lazarus0928240/components package_name_dir, lazarus0929251/components/package_name_dir.

I think I may have deleted the .o and.ppu file for contnrs because googling indicated that they may be corrupted or something.

I have tested this and it works but it does not accept the ~ . It needs the
full path name, it also rather odd because it does not allow the use of a
space between the option and the parameter.
Can this be set in the Lazarus environment as well, for all projectsm and

Does that mean that the I could also use make install INSTALL_PREFIX='~/LazarusInstalls/fpc240' command to install all the fpc versions into the same directory without their executable's clashing? I take it that the 'bin' folder in the INSTALL_PREFIX contains utilities which can be shared among the different installations, and that the 'share' folder will also have different docs for the versions. > Regards, > Sven > > -- > ___ > Lazarus mailing list > Lazarus@lists.lazarus.freepascal.org > http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus > -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
[Lazarus] How to pass path of fpc to make command, and some thoughts on Lazarus/FPC Installation.
I am trying to compile Lazarus from source using a different compiler and I have hit a snag. These are the steps followed so far, but I need to pass the path of the new fpc to the Lazarus make command. #create build and installation directories mkdir ~/LazarusBuilds mkdir ~/LazarusInstalls #fpc svn checkout http://svn.freepascal.org/svn/fpc/tags/release_2_4_0 fpc240 cd fpc240 make all PP=/usr/bin/fpc #use default fpc installed from Ubuntu package make install PP=/home/fchurch/LazarusBuilds/fpc240/compiler/ppc386 INSTALL_PREFIX=/home/fchurch/LazarusInstalls/fpc240 These are the issues I am having. 1. The fpc executable is installed in ~/LazarusInstalls/fpc240/bin/fpc When I execute ~/LazarusInstalls/fpc240/bin/fpc, the first 3 lines of output say: Free Pascal Compiler version 2.2.4-3 [2009/06/03] for i386 Copyright (c) 1993-2008 by Florian Klaempfl /usr/lib/fpc/2.2.4/ppc386 [options] [options] Obviously fpc calls ppc386 that is in the path, perhaps there is no fpc.cfg available. So how I can create an fpc.cfg and pass it the fpc I just compiled? Couldn't the install script create a suitable fpc.cfg to match the installation directory? 2. Onto Lazarus cd ~/LazarusBuilds svn checkout http://svn.freepascal.org/svn/lazarus/trunk lazarus27446 cd lazarus27446 make obviously fails here because I don't know the option of passing my shiny new fpc 2.4.0 to the make command. Is there an option for that, and are there other options to ensure that new compiler will only link with files from its subdirectories? There is also this hilarious bit in the README.txt that says. == Compilation: You don't need ./configure, just do []$ make clean all This will create the lazarus executable. Start it and enjoy. === What, doesn't even need FreePascal? There may be some legacy reasons why Lazarus/FPC doesn't use the ./configure approach, but at least a well documented bash script which allows you to set some variables before compilation would be very helpful. After all, the main idea of programming is never to use constants or literals where well documented variables will do /vfclists -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] Where does installer place files?
I have fixed that part, I was looking in the wrong directory. When I run fpc I get - Free Pascal Compiler version 2.2.4-3 [2009/06/03] for i386 Why is it still saying version 2.2.4-3? Did I get the wrong one from subversion?

[Lazarus] Where does installer place files?
I have just used the fpc package to install freepascal 2.4.0 from source in my home account, and I have done a make install PREFIX="" to install it to a folder of my choice, but I can't find locate the fpc executable there. There is a file named compiler/utils/fpc it gives a 2.2.4 version name, when I downloaded release_2.4.0 from svn. There doesn't appear to be a fpc.cfg file neither. -- Frank Church === http://devblog.brahmancreations.com -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
