Re: [lazarus] Compile fails on project with long pathname (MacOS X)
Tom Verhoeff wrote: I recently upgraded to 0.9.14 and started a project, whose code is in a deeply nested directory tree with fairly long directory names, where one of the directory names contains a space. When compiling from the ide, this fails at the assembler. It seems to report a cut off path (the part with the space is included), though this could only be in the message printed (and not in the argument that it received). Does anyone have an idea what is the problem here? Yes, I've had all sorts of path chopping issues. Especially it occurs if you specify the -o option to the compiler along with a -k option with some long paths involved. The FPC compiler uses almost all shortstrings to pass options to the linker. The problem does not occur until a total number of options add up to 255 - but it isn't as simple as just counting all your options and adding them up to 255 - rather some options are passed to the linker (such as -o) while others are sent other places, to for example the search functions that verify directory/file location of units in the uses clause. Some limits are not even 255 but rather 50. If you read the fpc-devel list you will see what I mean when I say that I've had the same issues. It generally occurs on computers that have several hundred projects, because when you have this many projects you do use long paths - while most people out there don't have hundreds/thousands of projects on their drive so the bug never pops up - or they just learn to live with it - I had these issues since day one when I was a newbie to FPC and I was blaming it on myself since I thought it was a newbie issue of my own. As more and more projects have been placed on my hard drive, the more the bug has popped up over and over again. Back when my hard drive was not as loaded, it didn't occur much, but did occur. It will require a lot of changes to the FPC source code since FPC source is heavily reliant on shortstrings, and the compiler will be slower. All testing for this bug should be done at the command line and the bug should be reported to FPC section rather than Lazarus section. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

You have to turn it around: Lazarus could have become so good because it's written in Object Pascal. Pascal which offers a good basic, structured language which makes it easy to implement an advanced, complex system with a group of programmers in a relative short time. Although readability is boosted I still find it takes years/months to make a complex project that does anything worthwhile in Pascal - or any language. And many C++ programmers are genius types - who could care less if the language is slightly more messy, because they have enough genius in them to understand it anyway. So it ends up being that a C++ program is just as easy to maintain if you are genius.

This way we can make those people and also also us happy. Of course I don't think those who don't pass by this situation should be forced to help implementing it. The biggest problem is that I cannot see the advantage of adding c++ for Lazarus for example, without allowing it to access LCL. This would make it just another text editor, and there is plenty already. Maybe a C++_to_pascal converter could help in this situation. The problem with mixing language is that you spend tons of time making workarounds for the difference between the languages. One or two similar languages like C and Pascal is not so bad but when you try and integrate a dynamically typed language and a strong typed language, and a few static and a few weak languages your IDE becomes one giant workaround instead of a solid dedicated product. For example, if the IDE was to handle PHP - would variables be declared in a strong typing fashion so that the IDE could parse the file and find the var declaration? No. There is no var declaration in PHP. So what good is the find declaration code tools item in the menu. So you'd have to remove that feature out of the IDE just for PHP - hence taking time out to make the IDE a workaround, instead of taking the time to do other things. And that bloats it up, with lots of workaround code. Unless you use a plug-in system which may be very very complicated and very well thought out - and even then, you still have to explain to the users how to download which plug-in for which language - instead of just shipping them one easy to install IDE dedicated to Pascal. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] Request for PR noise !
Being atheist means you beleive that he does not exist. Certainly not. Not seeing something where there is nothing and where it is not necessary that there is something is not a belief, it is a knowledge. I don't not to believe that there is a Rammstein CD in orbit around Pluto, I do know there is none (but don't ask me to prove it, I cannot). Does a dog have knowledge about colors? Can a dog imagine red, orange, blue, green, purple, violet, etc? A dog can only see certain shades - gray, some blue. So if you asked a dog whether he believed red/orange/yellow/purple existed, the dog would tell you that you are full of shit. Well, an agnostic dog, on the other hand would say I don't know - I'm not sure - maybe you are right, maybe you are wrong. Therefore you are agnostic, not atheist. Agnostic is not knowing, and let me tell you 100 percent of the world does not know anything about how or where the world was created, and how or where the thing that created that world was created, or whether it was a thing or not - or some figment of some thing's imagination. 100 percent of the world does not know anything - we are all agnostic. None of us are atheists, and none of us are religious. We all do not know. Otherwise, there wouldn't be so many different religions out there - if we KNEW what existed we would only have one religion. If KNEW that nothing existed, we would all be atheists. This is no the case. We know NOTHING, we are all agnostic. YOU don't know there are more colors out there than the ones we can see. If dogs cannot see certain colors, we ourselves may not be able to see certain colors. You do not know. We may or may not be the only being out there that can see as many colors as we can. But you do not know. Believing that we are the only being out there that can see all colors is like being atheist - you think you know something, but you are just as bad as those who believe in aliens or those who believe in god.

All of us who think this way should start a group/joint endeavor together because I am voting for the same thing, and I'm sick of all the folks out there who have real jobs and consider programming just a game that you play on the side. Or worse, the folks who are in school and participate in open source projects when they are at school, but then as soon as they get out of school and get a real job they ditch the open source project that seemed so right to them in school but so wrong to them once they found out that family requires a real job and a real living. Or the folks who work on an open source project but then Microsoft contacts them and immediately they go and work for Microsoft (hello, Gentoo founder - sorry to insult you).

Thanks for enlightening us. But this whole discussion has really nothing to do with lazarus/fpc/programming in any sense. I brought in a quote from Blaise Pascal for the basis of my posts. And you should familiarize yourself with Blaise Pascal as some of his quotes are very related to programming, if you look at them from a certain angle. Blaise Pascal has everything to do with the Pascal programming language since the language was named after him, didn't you know. And Wirth himself must have at least agreed with some of Blaise's points, otherwise he wouldn't have picked him for the language name. I wouldn't have brought the quote in, if it was from someone else other than Mr. Pascal. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] OT - Request for PR noise !
Upon your arrival for the final judgement you find yourself standing in front of Ra, the egiptian god. And he is pretty pissed that you were worshiping a false god. =) Wouldn´t that be funny?? Another quote from Blaise explains the answer to this.. I think Blaise says that no religions are wrong, they are all right. Personally, since I don't know - I don't know. And I stop there. I just don't know. So no point in choosing a specific religion if you do not know, and no point in choosing atheism if you do not know.. it just makes the most sense! Being agnostic still allows you to discover and look for reasons WHY and WHAT, it just allows you to not make a fool of yourself - because when someone asks you, you just say you don't know. Anyone intelligent can figure out that saying you DON'T know, when you don't know, makes the most sense. What's really funny is a lot of famous programmers claim to be atheist. (again, on topic). If you research Linus/RMS/And others.. But truly, I think they are agnostic - even Charles Darwin himself was calling himself an Atheist but then he changed later on in life - to agnostic. Some atheists don't discover that they are actually agnostic until further on in life - and this is okay. That's basically what I was saying - it is OKAY to not know, and it is OKAY to change your beliefs at some point in time too - for example I was under the belief that := was a stupid thing to use in a language since = is shorter when I first tried Pascal but my beliefs changed when I learned the reason why to use := and now = looks dumb when I see PHP or C code since it is not math-like at all. (again, ontopic - for the sensitive folks). If god exists, why doesn´t the other gods exist? What makes this god better or more probable? If you ask me, the most unprobably thing in the universe is life. How come out of Carbon, Hidrogen, Nitrogen and Oxigen, the essence of life be formed? Those are just 4 elements, unliving things by definition. Life comes from things not alive? Or is there soul? I beliave that we will have one of the most important answers we may have when we have a computer powerful enougth to simulate the brain. If it succeds and artifical life can be created, then most likely the soul does not exist. And we are just aglomerates of minerals. Computers can do lots of things that humans can't though - which is magical. Even cars seem like magic. Look at horses and compare them to cars. There are advantages to having things that are not like humans - you can't command a computer to do work - that would be slavery. But you can command a computer to do work and it won't feel any pain. So in some sense, we don't need to invent a human, we need to invent things that don't have feelings, so we can get stuff done with less human pain. We can only hack with existing matter so far, and we can't create the matter. So even if we make an artifical intelligence based robot, we still are only hacking with existing nature matter, and not actually creating anything. (and to stay on topic, for the sensitive folks, maybe the robot was powered by a Pascal program embedded into it's chips - although the lisp folks are probably thinking lisp, since Pascal is structured and mean to be commanded, while lisp is loose and meant to be expanded). _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] Lazarus Help System Requirements
Can anybody explain, why googling with: site:lazarus-ccr.sourceforge.net dynamicarray only gives two hits, but not http://lazarus-ccr.sourceforge.net/docs/lcl/dynamicarray/index.html It is a pity, that the most up to date docs are not completely indexed. I was just thinking along the same lines. Google is so busy, it takes a long while to keep indexes up-to-date against constant changing sites. This is going to be the only drawback of using Google to search docs. That's the catch22 - I deal with this problem every month with websites. Google indexes 200,000-500,000 pages one month and then next month it drops down to 1,000 or even 200. It's a roller coaster just like the stock market. This would be where having your own help doc indexing system would help. But to put less load on the freepascal/lazarus servers it is obviously wise to have a client side program indexing system like chm/local db/whatever. Still, more important than indexing the docs is writing them - if they weren't written, there wouldn't be anything to index - and Michael and others have done excellent job there.

Re: [lazarus] Lazarus Help System Requirements
As for the Websnap thing, I did not tought about it; but I once imagined that as we have support for gtk / qt / win32... we could have a layer for 'psp' so as to generate forms in web format. (And push it a little bit more and you can have a full AJAX application compiled with lazarus. But this kind of stuff is no more freepascal.) So a CGI that generate a perfect replresentation of a screen designed in lazarus could be done all from lazarus itself. Add the same features for reports,etc. That would be awesome. You switch from gtk destination to psp destination and the same project that was a stand-alone app becomes a cgi that can generate itself its visual representation and call back itself to process the commands. (That would require some javascrip... ajax crap). With CSS absolute pixel positioning (rather than relative positioning) to have things land on the screen at your desired destination using X/Y coordinates.. But as soon as you get into x/y coordinate positioning it means your app might be better off as a real thin client application anyway. But Ajax means no shipping of the application. At least it means that right now - in the future ajax might be able to read special config files in the form of cookies, or something - to me it seems sort of like reinventing thin clients.. but are there other advantages I'm missing of ajax, other than you don't have to ship it like you do a thin client (and you don't have to compile it). A good example of a thin client that works well, but is not ajax - AVG antivirus for windows. It is a real software application that connects to the internet every day to upgrade your virus definition. And it works perfectly. There was no need for AVG to become an ajax app because being a real app worked too - AVG could be an ajax app - you could log on to the AVG website and have it check your PC for viruses - but if it works well as a non-ajax app why not just ship it as a non-web program. Well I guess it means that AVG is stuck shipping their app, and that they could have used ajax if they didn't want to ship it - or they could have used VBScript based website. But is shipping really that hard of an effort? Shipping an app is a hard effort, but is it worth the effort? I think in many cases it's worth shipping an app - maybe in the cases where it is not worth shipping an app ajax is the solution? Well one advantage of AJAX is that no shipping or installing of the program is needed - but eventually if Ajax becomes complex enough that it can store data on your PC, such as config files, skins, etc, then I think it is essentially reinventing the thin client.. I mean let's say it uses cookies to store your skin or your configuration for the ajax app - well isn't this just a config file? So it really is just shipping a config file onto your computer in the form of a cookie - but if it gets complex enough that the cookie is to simplified and it needs to store other Lots of the work I do on the web actually requires my web pages to have tons of text on the pages so that my sites become popular on the search engines - so the whole AJAX thing is kind of wishy washy to me for those things.. but it is not always just about getting your thousands of text pages on the engines.. But I mean it also begs the question - if you are going to make an AJAX app why not just compile a lazarus application and send it to your users - have TCP/IP in the program connect to your web server, compile your lazarus app on all platforms and ship the EXE/ELF/BSDexe. I guess AJAX requires no shipping of the application, and no installation of the application. Right now my main focus with web development is building websites with 200,000-500,000 pages of content - or at least thousands of pages of content - so ajax doesn't help there much, but it could be useful for things like banking websites where people need to see a proper graph of their investments, and proper sessions on the website without sending an HTTP request for each little thing they do on the site (the whole point of ajax) Any-way this might not be the good place to talk about that. And this 'vision' is only mine. As far as I can see it, psp is actually a nice technology kit to build cgi apps for the web. You can join the mailing list if you like.. http://psp.furtopia.org/cgi-bin/psp/maillist.psp We have done some work with CSS/HTML to get direct positioning available on the screen - we try to use CSS whereever possibel and only use Javascript where absolutely needed Actually, Tony on our team has made a web application that is sort of like Ajax - it uses javascript and CSS/HTMl and is an mp3 player that works right inside the web browser, like a real software application works. In this case, Tony may have invented Ajax himself, but he just really wasn't calling it Ajax. I'm sort of a mix myself - I can see Ajax advantages but I also like building huge 200,000 page websites with

No PHP required really. A CGI program written in Pascal that calls some sort of database, and a desktop application that can call that database too. This keeps only one codebase needed for the entire help system - the same database is used for both the web docs and the desktop docs - just that the desktop doc is using an embedded database while the web application may use a real full fledged version of the database. But most websites will only need to use an embedded database because 99 percent of all Pascal applications are not going to have high traffic websites that require a database that can do complex queries fast. Especially on help documents which people will rarely be checking on the website, since they have a local copy - the online docs are mainly for promotional purposes to get a bunch of keyword heavy pages out on the net promoting your software. The reason I currently use Google to search for freepascal documentation on the RTL instead of using my local copy of my help documents, is because Google itself is my database that powers the search of the freepascal documentation. Some of you just use grep maybe - I laugh at those people. But if I had a proper local database there would be no need to search google. Whether the database is a CHM database or an embedded DBF or SQL database doesn't matter - the disadvantage of CHM is simply that I can't port CHM to the web database in one shot - since a CHM database won't work on a website. And for those special cases where you have a Windows CE computer, that can't run an embedded database? Think again, most likely someone has already ported the database to Windows CE. CHM format was never intended to work on Windows CE so CHM be an external dependency, as you'd have to have the user download an external CHM reader for Windows CE. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Implementing this with the FPC would probably be proof enough that Pascal isn't dead. This is very very hard to do. It could be done with a plug-in system - if you unload the Pascal parser then the IDE is no longer a Pascal IDE but now a C++ ide. For example, CodeTools/CodeInsight needs a parser to parse the text in the IDE window. You'd have to be able to unplug the Pascal CodeTools parser and plug another language CodeTools parser in. But this is much more man-power required than just focusing on one language. Look at Vim and Emacs - they are supposedly the tools which are supposed to handle multiple languages. But what good are they? Don't we have to build Emacs plug-ins in Lisp? Why not Emacs plug-ins in Pascal? There is always some language favor it seems. And Eclipse? It is favored for Java - even though it's supposed to be a multi language development tool. And as for BDS2006? It only handles C++/Pascal but why not Lisp, Perl, PHP? If Borland doesn't have the man power it is very slim chance that a small open source project can handle such a task. And then we have to beg the question - where do we draw the line? Which languages do we skip? Perl? Python? TCL? Algol? Right now it is easy to draw the line - Pascal. It's a very easy line to draw. If you let this line slip - it becomes very hard to draw.

Re: [lazarus] Suggestions for Improvement
2. Replace the delphi dfm with a real code init (java style). What are the advantages? Easier component creation control/management via ONE language. 1) Please do not forget, that then you will be able to Search / Replace on component properties if they are in code! Currently the Delphi (and Lazarus I believe) doesn't seach dfm or lfm files when you do a normal search. You can still search and replace - you just store all the design time components in an include file. Instead of design time components via an DFM object file, you use an include file with true Pascal code, not DFM object code. When you search for stuff in your code, the include file is not searched - just as the DFM file is not searched when you search in Delphi. The include file hides all the design time code so it does not bloat up your code logic with design code. There are real world examples out there that uses this exact system. KOL/MCK does it inside the Delphi IDE, and there is no difference between editing a property of a MCK component from editing a property with a DFM component - the only problem was that Delphi is designed highly around a DFM system - so KOL/MCK had to implement tricks to get it working in Delphi. But with an IDE that is not proprietory, no tricks would be needed. Back when I started using delphi, I wondered what black magic was creating my forms for me? Why couldn't I see and tap in to the code that created my forms? I guess curiosity kills the cat. 2) As anybody accidently deleted a component from a form. Afterwards, you don't have a clue as the what custom options where set and what other components it linked to. Have then is lines of code minimizes this issue (yes Source Control software does help in such cases, but not everybody uses source control software - poor folks). You still use a component pallette and visual design. You still delete and link components together. All components are still linked to each other the same way. You just link the components through the code instead of through an object format. Take Synedit for example: Synedit1.highlighter:= SynPasHighlighter; Your highligher is linked to your synedit component. Instead of unlinking it and linking it within the DFM file, you do so in the include file with real code in it. There's no difference from an end user perspective who is using the IDE - components being dropped on the forms will act just the same as if you were using a DFM file. There are advantages and disadvantages of using real code versus using DFM files. DFM files are a cleaner format than actual Pascal code. Real code is easier to peak into and copy/paste than DFM files (but a DFM to code converter can be made). DFM files make the exe bigger in size than run time code, generally speaking. Now the question is: what does Java do this in its Visual ide's? Does it create an include file with component properties stored as real Java code - or does Java dump all the code into your Java source files and not modularize it? I'm interested because I haven't tried any visual Java ide's.

Re: [lazarus] New help doc format?
Does Apache Server work on Windows CE? So I shouldn't use Apache for a webserver, just because it isn't truly cross-platform? Sometimes people get carried away with the whole cross platform advantage - when really there would be no advantage of having Dude, you are missing the point completely!! Apache run on Windows CE. I don't know why anyone would write or read documents on a small Windows CE computer. Maybe if you are on an airplane and you only have your GameBoy with you - how will you read the Docs? Windows CE is just like any other platform!! Windows, Linux or OS X. Just because it's a small form factor makes no difference. Loads of people make a living writing software for the PDA market. I have helped develop a Time Sheet software package for a 2000+ employees company in the UK, and yes the application needed a help file (as does any good software application)! Why may the PDA market not have help files? It is a software application that should be shipped with help. You are right - I thought we were purely talking about the documentation for the FP compiler and the Lazarus IDE itself. When I am a developer I usually have a LCD/CRT monitor and would never ever read freepascal compiler documentation on a Windows CE computer or Lazarus Documentation. If we are talking about a generic help system for applications that are generated with Lazarus - then it is a different story. Although, like I pointed out - SQLite does appear to be available for Windows CE - so my case doesn't change. But then again, I'm not really advocating SQLite - it would be nice to use a Pascal based help system. What I'm mainly trying to point out is that if we are going to be doing indexing and sorting, are we not reinventing the database - since databases do all these things for us? Why would we want to index XML files if we can dump the content into the database and have it indexed for us by the database? In otherwords - does the developer really want to spend time reinventing an indexing system when someone has already done that for us in the database? In some cases, we must reinvent a bit in order to have a nice custom solution. So would everyone please point out the reasons we cannot make use of a database and why we really need to invent our own help database - if there are plenty of databases out there. Also - will the custom database solution like CHM (I consider CHM basically a reinvention of a database - a custom one) be web ready? i.e. can I upload the CHM file to the internet and create a web program that allows users to search the documents on my website? With a real database you can upload your help documents to a web server and create a web program that searches your docs. Then your company will get much more promotion if your help files are online in addition to you offering an off-line doc system. So can CHM be searched, indexed, etc. online on the web, too - and not just offline? with several people querying it at once? I think CHM is mainly designed for one person querying it. With a real database I would ship a small embedded database to the user - which one user can query comfortably. But then use a full fledged firebird/mysql style database on the web server to serve the docs to hundreds of people. Can CHM some how be uploaded to the web and have multiple people querying it with reasonable speed? Or must a real database be used? If a real database must be used - it means that you will then have to convert that CHM file to a real database anyway - so you now have double the work instead of just using a database in the first place. Are there enough advantages of NOT using a database. That's what needs to be decided. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] New help doc format?
I think you are one of a selected few. CHM is basically compiled html files into one file. Why would I want to see the code of each help file I am viewing. All I want in the content. A single file is great for distribution (smaller and easier to copy) compared tho say a 1000 html pages with there external images in the mix. Well I like having the HTML available that I can edit in a source file in case I need to print the documents and the current format is not good for my printer. Sometimes I change the font size of the documents so I don't waste as much paper. I don't like having the file hidden in some CHM file that I can never have access to with my bare hands. If there is a CHM decompiler that is legal to use and not illegal then that would be good. Or if you offered HTML and CHM that would be good - can you extract all the HTML out of CHM legally? Because one time I tried to decompile a HLP file and it turned out to be a huge mess. Also the corruption comment makes no sence. How often does CHM files get corrupt? It's never happened to me (maybe I am just lucky) Why would any other single compressed file be any different? That would be like saying any .zip or .rar or tar.gz file is not a good idea. Well when I back up my hard drive I do not dare put it into one zip file. I've had 3GB zip files damaged before. Instead I use several zip files instead of one big one. But in the case of a CHM file corruption is not much of an issue since it probably won't be written to often, and the user can redownload the CHM file any time he wants. I've also had several microsoft formats go corrupted on me such as giant email files that are stored in binary form in one big file. Losing all your email is not fun. But for CHM format, again, it is not as big of an issue since you could always download the CHM file again. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] Suggestions for Improvement
Back when I started using delphi, I wondered what black magic was creating my forms for me? Why couldn't I see and tap in to the code that created my forms? I guess curiosity kills the cat. You can edit the .dfm. Just not the form and the dfm at the same time. The DFM never told me when the components were created and freed, was what I was getting at. I wondered, as a beginner, what black magic allocated and freed the memory to create those forms. Long ago I was learning about run-time component creation and I wanted to modify my design time forms to be run time, by finding the actual code that freed and allocated the design time forms. I was looking for the code so I could turn my components into run time ones without writing all the run time code myself. I wanted to peak into the code and find out where form1 was created and freed.. couldn't do it. (could have maybe if I knew about GEExperts component to code tool). 2) As anybody accidently deleted a component from a form. Afterwards, you don't have a clue as the what custom options where set and what other components it linked to. Have then is lines of code minimizes this issue (yes Source Control software does help in such cases, but not everybody uses source control software - poor folks). You still use a component pallette and visual design. You still delete and link components together. All components are still linked to each other the same way. You just link the components through the code instead of through an object format. Take Synedit for example: Synedit1.highlighter:= SynPasHighlighter; Your highligher is linked to your synedit component. Instead of unlinking it and linking it within the DFM file, you do so in the include file with real code in it. There's no difference from an end user perspective who is using the IDE - components being dropped on the forms will act just the same as if you were using a DFM file. Binary properties can be difficult to set in code. Like images/resources? There are advantages and disadvantages of using real code versus using DFM files. DFM files are a cleaner format than actual Pascal code. Real code is easier to peak into and copy/paste than DFM files (but a DFM to code converter can be made). DFM files make the exe bigger in size than run time code, generally speaking. DFM make the exe smaller. It is the streaming code, that needs quite a lot of code. But this is a rather fixed amount. So for big applications or if the library is in a .dll/.so the DFM mke the exe smaller. You say DFM make the exe smaller, period. But you should say - DFM make the exe smaller in some cases only. : Because I've never seen a DFM exe smaller than a non-DFM exe myself, but I'll take your word for it. All the applications on my hard drive are several small and only some medium size programs - I make a lot of small utilities with only 1-5 forms in them. I don't make many large applications that exist all inside one exe - most of the time I make a bunch of small programs - then if I have one large program where I think a small add-on would be useful, I make a plug in system. So it depends what the threshold is where the DFM does make the EXE smaller, I guess. If it requires that 5-10MB exe size exist before you start seeing gains in exe size - that doesn't really affect me.. with the work I do. I generally like to make the program have a plug-in system once it gets that large anyway, so it would actually be more advantageous for me to have a lower threshold. Do you know generally what the threshold is before you have seen the exe become smaller from using DFM? 5MB? 6MB? Lazarus is quite a nice and big application and is only 6MB. I would think lazarus would be maybe 10MB in size, but it is only 6MB.

Re: [lazarus] Lazarus Foundation pros
Hi. What they need is people. They (we?) don't need a foundation to make a better website, but we need someone to make a better website. Obviously the core developers don't care much about that. They have other interests. Your idea of, making some improvements to the community as an alternative of a foundation, sounds good... The problem here is that people disagree on what SHOULD run the website - some think current php used is fine to power the website. Some think it should be powered by perl. Some people feel it should be done in PEAR or phpnuke. Some feel it should be powered by websnap style lazarus website engine. Some people feel it could be done in PSP. If you had someone in charge to say listen Mr. we are paying you $400; If you want the $400 you build it the way we want based on our manager's instructions. But there are no structured rules or instructions, so no one will ever get it done - except the core folks when they have time. It's not as easy as just saying we need people - do the work now. You must discuss WHAT must be done and you must have some structure and management. Otherwise it's just an open can of worms with 50 guys battling (talking) about WHAT engine should be used for the site. It's not as simple as opening up lazarus and having some guy build the website.

I can answer that. It isn't taught in school at all. If you go to any school and I mean any school that teaches CompSci in any way they will tell you that, Pascal is a dead and useless language. Nobody uses Pascal anymore. This was almost the exact quotation I heard from people on a local linux mailing list community when I mentioned something about Pascal.. The best way to respond to people like this is to help them with their Perl problems once in a while.. they will respect that you helped them, then they might respect you more for what language you use. I know nothing about perl but I still answer some questions because the languages have something in common when it comes to a certain way to solve a problem, etc. It's sort of passive marketting, as opposed to active marketing.

Re: [lazarus] FPC/Lazarus Foundation would need people
In all of this talk about the need for a foundation it has been said how we could have these people doing this job instead of the developers. We could have others doing other jobs, etc. etc. etc. Well as the statements point out this needs people. It needs people that are involved and interested in FPC/Lazarus. That is where the problem starts. It's not just people doing work though - it is also communicating about the attitudes of the current people in charge too. The current attitude consensus is that it's just a hobby. On every single successful project, there is always lots of discussion and lots of code. Not just lots of code alone. Lots of code alone are the one man developer projects that become a selfish endeavor of one attitude from one developer (if two developers are on the project, it leads to two different code bases because of disagreement and no discussion on plans). Some of our attitudes our not in line. Some of us will and already are using FPC/Pascal for real work.. and pleasure too. But not just pleasure and not just hobby. What scares me most is the hobby attitude because I know FPC is much more than just hobby quality. It's not just as simple as gathering an army of programmers together and doing lots and lots of work. I've had conflicts of attitude before and it doesn't matter if you are both very hard workers, if your attitude isn't the same then you can code all you want but you might disagree on the goals of the project and start your own project. This is why OpenSource/Mozilla/OSI licenses spouted off from GNU - because people didn't agree on the same ideas. RMS is a good Lisp programmer and so is ESR, and they can pump out lots and lots of code - but that doesn't mean they will work good together. With FPC camp right now, we have two crowds or camps: 1. Those who want FPC to be successful for serious use, but hobby use is nice 2. Those who only want FPC to be hobby, serious - nahh - serious ruins the fun. I am part of camp 1 because I currently use FPC for serious use. I also use it for hobby too. Look, if we only use FPC for hobby and then we go off and use a real tool like MS VC or GCC for real work, how does that make FPC look? I feel that less of a hobby attitude is needed, otherwise people will get a feeling about this open source project they just work in their spare time, it's not a serious project - only a hobby for fun. But, this is all too common in many open source projects... On the other hand if it becomes too serious of a Business compiler it may end up being a corporate buzzword society. Have to balance it out - don't go too far as to making FPC a buzzword Borland style group - but please, at least admit that FPC is more than hobby quality. Some of you might be thinking will FPC split into two projects such as FreeBSD/NetBSD/EtcBSD split up? This would only happen, if some core developers had different views - right now I think ALL (Every Single One) of the core developers is part of camp 2, not camp 1. Yes, Camp 2 is doing more of the core compiler work - so it means they have more control. It could also be though that the core developers are just humble folks, and they do intend for these projects to be serious quality - and when they say hobby, they are just being really humble. I think this is true, because I know FPC is more than just hobby quality - and the documentation, and everything else about the project. As for Lazarus, it is more on the hobby quality side - being honest - since it is a huge project which isn't as near complete as FPC is.

Which is why those who can are switching to gas (which, lo and behold, farmers can produce that themselves) and hydrogen and trains anyways. The only problem is the lag of the infrastructure, that is, inertia. But that wasn't the point, I see. And as for hydrogen: how do you make hydrogen? By using energy to first get the hydrogen? I'm not familiar with the process. I know you can make hydrogen from water, by dissecting water into pieces through electrolysis. But this costs you energy - the electricity that it takes to make hydrogen may be more than what you are in fact getting OUT of the hydrogen that you produce. I'm not sure though. Then again, it does cost us money to run oil rigs and etc. - and we do get more oil out of the ground than it costs us to retrieve the oil. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Hi, the current copies of Lazarus that another developer and I are using do not seem to have a subfolder or subdirectory checkbox for refactoring. Do any lazarus versions contain that feature. Sort of like the search/replace tool in lazarus where you can recursively search subfolders. Do you mean, you want a fifth option in the refactoring dialog 'project directory and sub folders'?

You could split the file into pieces and rejoin it together later. I'd do it in 100MB splits, or 50MB splits.

Problem is a 10GB file won't fit on a CD, so you have to pause the splitting process and resume it later, after entering the second CD in the drive.

Anyway it was fun to build the program.. the real problem was my google skills weren't good enough. Some times I don't know what a certain feature is called. Resume splitting? I don't know. I needed to learn a bit about splitting files in Pascal, so I wrote a util to gain some pascal knowledge. Unfortunately I didn't come from the TurboPascal days where it was very common to split a file onto several floppies. I don't have that experience. :-) p.s. just buy EditPlus and skip Synedit. It's faster than most Synedit based editors. Just pay the $30 for EditPlus already and quit the Synedit nonsense. But of course, synedit is fun to learn about and can always do more then editplus will ever be able to do, due to extensibility.

Unless you have in depth knowledge about how every bit of ansistring memory management works, using getmem and freemem and pchars are simpler, no?

Now, if you are an expert in battling the automatic memory management maybe you can battle ansistrings enough to be almost or just as fast as pchars. Is this what we are doing in the fpc sources? I will have to look, and see. Yes. For example: The codetools use ansistrings. Less than 1% use PChars. Just avoid the + operator as you would avoid ReAllocMem and StrCopy. However, string[i] isn't so convenient as the '+' operator because you have to think about all your calculations quite a bit. Really string[i] is smart pchars. Stringbuffer type would allow you to use the + operator and eat your cake too, because every time you use the + operator the getmem() is not called. Further benefits of StringBuffer type will have to be explored - at this point it does'nt have enough benefits to be justified since you can just get along with string[i]. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

Re: Mozilla Plugin Panel component
Just wondering how exactly you are doing it ? Are you linking to gecko or embedding the window itself ? If the latter, the way under the linux is to I embed the window itself. No reference to Gecko at all, though that was my first attempt at the component. I found an article on the Borland Developer Network about how Borland managed to get Gecko embedded inside an application window for Kylix. It was a bit ugly though. It would have been nice though, because then I could use any plugin Mozilla supports or display fancy html (with CSS) inside the window. Even control it via Javascript would have been nice. :-) On Winblows you can embed any application inside a window with SetWindowPos, although I'm not sure how much CPU it takes to continually readjust a window with SetWindowPos. (setparent does not work because of the application belonging to a separate process space) Then send messages to the application's API. To make it look even more embedded, turn off the top window title bar with another API command. Of course with all the dumb Windows XP skins out there, each application probably won't match your parent application anyway. This trick is much easier to use if your applicaiton uses a generic skin. i.e. the standard OS skin default. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives
Re: [lazarus] Object pascal a Modern Language
I guess it's not so hugely useful or else someone would have contributed it already. Mmm... if that was the case I wouldn't be programming because everyone has already implemented what I'm trying to program :-) Seriously though - it would mean less calls to SetLength when doing big operations on strings. Ansistrings work fine when you are doing small random concatenations but when you do tons at once they are much slower and you must resort to the following: setlength(string, NewMaxValue); string[i]:= 'string I want to concatenate'; instead of string:= string + 'string I want to concatenate'; If it helps, we could add a function to TStrings: Function TStrings.Concatenate : String; begin end; Which would optimize the whole matter into a single 'getmem' call ? if there is interest, I can add it.

But I mean if you are doing things at different times in the program: for i := 1 to 1000 DoSomestuff s:= string + string; DoOtherStuff s:= string + string; in other words.. not one big concatenation at once such as: string.concatenate(string1, string2, string3, string4); The only way I saw it possible in my mind was through a special string buffer type (or hey, even a stringbuffer class if not a true system type).

Re: [lazarus] Object pascal a Modern Language
No, if you need pointer _arithmetic_ you are doing it wrong or using a language that is assembly in disguise. Pointers itself are fine and dandy, but don't *(x + 3 * i + 2) = *(y - 3);. Would you talk like that to a human? No? Why talk like that to a computer then? It's just a sign that something in the language is broken when you need to do stuff like that (except when writing a heap memory manager, I guess). But I mean when you need to do it like all the time, like for arrays (hello C :)). Also, by doing stuff like that you throw all bounds checking out of the window, so you could as well write it in assembly and spare yourself the hassle of using a compiler that brags all the time except where it matters. I've decided that C is now officially the learning language for universities. Students will now learn about all sorts of computer memory management in C, but C will never be used for any practical purpose. It serves as the teaching language of what language we should never use but teaches us a lot about the memory in a computer. It also serves as a language which makes a programmer feel happy I'm glad I learned C because it was 8 times harder just to create a string, and now I'm ahead 8 times by not using C. If I wouldn't have learned C I wouldn't have known I was 8 times ahead. As an aside, I remain adamant that anybody who writes a free software/open source program in Java is being foolish. What is the POINT of a free software program that REQUIRES a non-free program just to RUN ? I've also wondered about that.. I mean there is gcj and mono and such, but... why not do something that is better but our own thing... I've looked at parrot for a vm but it's tailored for interpreted languages only. sigh.

system. So a new feature could simply be added and totaly integrated to
the original application. It is important to note that the application
has no idea what is going to be added later.
Any ideas anyone?
Notes:
If you want people to build plug-ins in other languages than Pascal (visual
basic, C++, C, etc) then don't use ansistrings or objects since they are
specific to Pascal.
Who is your market? People who own copies of Delphi/FPC or people who own copies
of Visual Studio, Delphi, VB, FPC, and more?
If using a DLL system and you want to export ansistrings from a DLL you can use
a memory manager trick similar to the trick being used in Pascal Server Pages
1.6.X project.
The memory manager trick to export ansistrings from a DLL is:
program MySoftware;
// export memory manager from executable (software hosting the plug-ins)
procedure ExportMemMan(out MemMan: TMemoryManager); stdcall;
begin
GetMemoryManager(MemMan);
end;
function TestAPI: string;
begin
result:= 'hello, this is the API in the exe ';
end;
exports
ExportMemMan name 'GetSharedMemMan',
TestApi;
begin
end.
library MyPlugin;
var
GetExternalMemMan: procedure(MemMan: TMemoryManager);
TestApi: function: string;
MemMan: TMemoryManger; //storage of received mem manager
begin
// get handle of EXE
ExeHandle:= loadlibrary('yourprogram.exe');
// import exe memory manager into DLL plug-in
GetExternalMemMan:= getprocaddress(ExeHandle, 'GetSharedMemMan');
GetExternalMemMan(MemMan);
SetMemoryManager(MemMan);
// You can now use ansistrings in dll
TestApi:= getprocaddress(ExeHandle, 'TestApi');
showmessage( TestApi() );
end.
Above ansistring memory manager trick should work with FPC and Delphi plug-ins,
which means Delphi developers and FPC developers will be able to make plug-ins
for your program, not just fpc developers.
The most powerful plug in systems have communication systems both held inside
the exectuable and the dll. Many people make the mistake of thinking only the
DLL can export, when in fact the program itself can contain an API of it's own
that is exported which the DLL can talk to. A simple example plug-in system that
uses an API held inside the EXE is implemented in LazarusRB in plugger_api.pas
If it is objects that you need to export then you can make procedural wrappers
that export each and every procedure/variable from that class, then reimport
them with a wrapper again. Take a look at LazarusRB sources for an example of
that system in plugger_api.pas and PluggerWrapper.pas.
Or of course you also can wait until fpc is able to export BPL style packages,
which again will only work with FPC and not plug ins built with Delphi or other
languages like C/C++/VB. It depends on your needs and the type of program it is.

Re: [lazarus] win32 program icon
Recently, support for {R$ } directive on linux was added to the
compiler. I don´t know how this helps, however.
no idea what that's for in practise... Unix usually goes the other way,
separating everything, not stuffing everything and their brother into
one file.
I guess the advantage of having something in one file are that there is no
dependency
hell. That and you can move around the one single file in a file manager without
worrying whether 5 files need to be copied with it or just 2 with it. If you
copy
just 3 and you forgot the other 2 dependent files you run into dependency hell.
I guess there is a point in which the line shall be drawn - the Windows
registry is
one big file and it is a giant piece of hard to access dangerous un-recommended
crap.
I find as an application gets larger in size, more things need to be separated
out.
Same with websites - template files and CSS stylesheets are more and more
useful as
the site gets bigger. But for prototypes and quick RAD applications, it is
sometimes
better to have things in one single pack with the ability to expand outward
later
(bigger apps uses packages, dynamic libraries, settings files, resource files,
but
quick rad prototypes are easier to ship in one single executable).

Re: [lazarus] Who Discussed Linker Slowness?
What do PPU files contain? symbolic links or hard links? See below: - The .TPU format doesn't contain symbolic links to other units, it contains hard links to particular offsets in the interface part of other .TPU files. If those other units change their interface, the .TPU is made obsolete and needs to be recompiled. - Any reasonable update beyond a minor bug fix release is likely to change the interface of some commonly used units like SYSTEM. This makes everything obsolete. - Borland chose to do things this way because it leads to drastic speedups in linking. Essentially all the work involved in linking a unit to the units it uses gets done during compile time, and doesn't need to be repeated again when the program is linked.

So in short: The only way to get a major speedup in linking is to have an internal linker so the .o is not needed anymore and can be stored in the ppu. But i don't have the time to code such an internal linker so don't expect anything before 2007.

All those external references to DLLs are generated by the linker and don't need to be stored in the dcu. For FPC we can do the same since ld now also supports direct linking to DLL files.

Re: [lazarus] Help with DLL (using pchar, etc.)
Yes, this is my favourite. As you can imagine, on embedded nano-computers every single byte has to be checked if it does something useful, the other ones have to go home. ;) Do you think the PStrList will be useful, and some other fake (byte friendly) classes (objects) in CompactUtils? I know pure arrays and and simple variables without any objects at all, will save bytes, but hey wouldn't it be nice to have some of object oriented programming without the cost of bytes? Yes in your case embedded programming will not benefit from DLL programming of course - in fact dll programming is more inefficient than static linking because with static linking you don't have to load the entire DLL with wasted functions in it. I'm not one of those dudes who is anal about having Exe's small - it's just a matter of having a leading advantage of being able to upload a nice small 30kb powerful CGI program and of course being able to work with embedded systems. That is one advantage with FPC is being able to work with embedded systems, over say python or perl. I'm sure people would love working with Pascal rather than C for embedded systems, but in order for Pascal to have a chance in embedded systems we must have projects like this compactutils and system.ppu replacements, otherwise people will have to resort to C. Because the big 30kb hello world exe and the 90kb hello world exe with sysutils in the uses clause is not good for embedded systems. _ To unsubscribe: mail [EMAIL PROTECTED] with unsubscribe as the Subject archives at http://www.lazarus.freepascal.org/mailarchives

I know that maybe it is possible for fpc to create its own linker, but if the gnu linker speed can be improved we might as well make use of it. If anyone finds some mailing lists or internet sites that show discussion if the gcc/gnu linker speed being improved (or why it is slow) please post in this thread. If no one has even made a note to the gcc tool chain team that the linker is slow, maybe they won't improve it? Maybe they feel people are satisfied with the speed?

Re: [lazarus] Help with DLL (using pchar, etc.)
As an experiment for CompactSysUtils project I started a while ago, I have used this opportunity to demonstrate why FPC should reorganize the FPC sysutils unit for better smartlinking (i.e. create just one more unit than just sysutils to take care of smartlinking). Many functions in the FPC sysutils unit do not rely on any finalization or initialization code. By simple copy and pasting some of the sysutils functions into a unit of my own, called CompactSysUtils, I have gotten the DLL down to 40KB which was previously 91KB Project files showing 40KB DLL versus 91KB DLL is here: http://z505.com/pascal/MD5Hash/MD5Hash_COMPARE.zip CompactUtils and CompactSysUtils project is here: https://opensvn.csie.org/pspcgi/psp-lib-1.5.0-devel/src/extras/CompactUtils/ In order to compile the CompactUtils version in that zip file, you will need the latest copy of the compactutils.pas and compactsysutils.pas which is located on the SVN link above. Sometimes we don't worry so much about bloat like this since today's processors are getting faster, but this one is a no brainer. There is no work to be done other than copy/paste functions and reorganize them such as I have done with CompactSysUtils project. I have also made notes about this before on the mailing lists, such as mentioning how the findpart function can be cut copied and pasted right out of the StrUtils unit so that no sysutils initialization and finalization is hauled in. Maybe people can learn from this with the lazarus project too - as I'm guessing some (not all) the reason lazarus exe's are so big is because or simple initialization/finalization bloat. Sure there are abstraction bloat that is incurred for multi-platform programming in SOME CASES, but I've just proved with above CompactUtils project that abstraction has nothing to do with the majority of the bloat in this case. Rather simple reorganization in this case, to cut the EXE and DLL in half (actually, *more* than half). So either I continue to maintain this compactutils project with my elite cutting/copying/pasting skills or the FPC team decides to reorganize sysutils at the distribution level (i.e. kill the compactutils project and just do it in the RTL itself).
